1.
Where ..... (buy) this TV?
A) Did you bought.
B) Did you buy.
C) Were you buying.
D) None of the above.
Show Answer
Explanations:
Option B is correct because "Did you buy" uses the past tense auxiliary verb "did" with the base form of the modal verb "buy," which is appropriate for forming a question about a completed action in the past.
Option Analysis:
Option A:
Incorrect. The sentence should use "did" instead of "bought."
Option B:
Correct. Uses proper auxiliary and base form for asking about past purchase.
Option C:
Incorrect. This is a question about buying, not an ongoing action.
Option D:
Not applicable as Option B is correct.
2.
The road ..... (repair) for days before the rains came. (Past perfect continuous)
A) Was being repaired.
B) Had been being repaired.
C) Has been repaired.
D) Had been repairing.
Show Answer
Explanations:
The sentence requires the use of the past perfect continuous tense, which is formed with "had been + present participle". This tense is used to describe an action that started in the past and continued up to another time in the past. In this context, the road was being repaired for days before a specific event (the rains came) occurred in the past.
Option B ("Had been being repaired") correctly uses the past perfect continuous tense.
Option Analysis:
Option A:
"Was being repaired" is present perfect continuous, not suitable for describing an action that started and continued up to another time in the past.
Option B:
"Had been being repaired" correctly uses the past perfect continuous tense.
Option C:
"Has been repaired" is present perfect, indicating a completed action with current results, not suitable for describing an ongoing action up to another time in the past.
Option D:
"Had been repairing" is incorrect as it uses the gerund form instead of the correct participle form.
3.
The building ..... (finish) by next month. (Future perfect)
A) Will have finishing.
B) Will have been finished.
C) Will be finished.
D) Will have finished.
Show Answer
Explanations:
The future perfect tense is used to describe an action that will be completed at a point in the future. The correct form for "will have been finished" indicates that the building will be completely done by next month, which aligns with the future perfect construction.
Option Analysis:
Option A:
Incorrect. "Will have finishing" is not grammatically correct.
Option B:
Correct. "Will have been finished" accurately uses the future perfect tense to indicate completion by a future time.
Option C:
Incorrect. "Will be finished" uses simple future, indicating an action that will occur in the future but not completed by next month specifically.
Option D:
Incorrect. "Will have finished" implies the subject has already finished something and is about to do it again, which does not fit the context of a building being finished for the first time by next month.
4.
The meeting ..... (cancel) if everyone agrees. (modal verbs)
A) May cancel.
B) Should cancel.
C) May be canceled.
D) Could cancel.
Show Answer
Explanations:
The sentence "The meeting
may be canceled
if everyone agrees" uses the modal verb "may," which indicates a possibility. The passive voice "be canceled" is appropriate here, as it shows that the cancellation could happen without specifying who performs the action.
- **Option A: May cancel** - Incorrect because "cancel" should be in passive form to match the subject "The meeting."
- **Option B: Should cancel** - Incorrect because "should" implies a recommendation or obligation, not just possibility.
- **Option C: May be canceled** - Correct as it uses the modal verb "may" and is in passive voice.
- **Option D: Could cancel** - Incorrect for similar reasons to Option A; it should use passive form.
Option Analysis:
Option A:
Incorrect. Active voice without passive construction.
Option B:
Incorrect. Implies obligation or recommendation, not just possibility.
Option C:
Correct. Uses modal verb "may" and passive voice.
Option D:
Incorrect. Active voice without passive construction.
5.
When we ..... (come) to the concert the music started.
A) Were coming.
B) Came.
C) Come.
D) None of the above.
Show Answer
Explanations:
The sentence "When we came to the concert the music started" uses a simple past tense verb ("came") to describe an action that occurred in the past, which is appropriate for this context. The phrase "when we came" indicates a completed action in the past leading to another past event (the music starting). This structure does not require a continuous modal verb.
Option Analysis:
Option A:
"Were coming" suggests an ongoing action, which is incorrect for this context. The sentence describes actions that have already happened.
Option B:
"Came" correctly uses the simple past tense to describe a completed action in the past, making it the right choice.
Option C:
"Come" is in the base form and does not indicate a completed action, which makes it incorrect for this context.
Option D:
"None of the above" is not necessary since option B is correct.
6.
They ..... (drive) very fast when the car hit a tree.
A) Was driving.
B) Were driving.
C) Drove.
D) None of the above.
Show Answer
Explanations:
The sentence describes an action that was happening at the time of another event (the car hitting a tree). This is indicative of the past continuous tense, which is used to describe an ongoing action in the past when another action occurred. Therefore, "Were driving" correctly conveys this meaning.
Option Analysis:
Option A:
Was driving does not fit because it suggests a simple past tense, indicating a completed action rather than an ongoing one.
Option B:
Were driving is correct as it indicates the continuous nature of the action at the time of another event in the past.
Option C:
Drove implies a completed action and does not indicate that the action was ongoing when the car hit the tree.
Option D:
None of the above is incorrect because Option B is correct.
7.
Hw cut his finger while he ..... (cook) dinner.
A) Were cooking.
B) Cooked.
C) Was cooking.
D) None of the above.
Show Answer
Explanations:
The sentence "Hw cut his finger while he was cooking dinner" uses the continuous form of the verb "to cook," which is appropriate for describing an action that was happening at a particular moment in the past. The structure "was + verb-ing" indicates an ongoing action, fitting well with the context where Hw accidentally cut his finger during the process of cooking.
Option Analysis:
Option A:
Incorrect. "Were cooking" is plural and does not match the singular subject "he."
Option B:
Incorrect. "Cooked" is in simple past tense, which does not fit with the continuous nature of the action described.
Option C:
Correct. "Was cooking" properly conveys an ongoing action at a specific time in the past.
Option D:
Incorrect. There is a correct answer among the options provided.
8.
By the time she arrived, the presentation ..... (complete). (Past perfect)
A) Had been completed.
B) Had completed.
C) Has been completed.
D) Was completed.
Show Answer
Explanations:
The sentence "By the time she arrived, the presentation had been completed" uses the past perfect tense ("had been completed") to indicate an action that was finished before another past action (her arrival). This structure is appropriate for showing a sequence of events where one event occurred before another in the past.
Option Analysis:
Option A:
Correct. "Had been completed" accurately conveys that the presentation's completion happened before her arrival.
Option B:
Incorrect. "Had completed" uses the simple past perfect, which does not fit the context of a continuous action up to a point in the past.
Option C:
Incorrect. "Has been completed" is in the present perfect and refers to an action that started in the past and continues now or has just finished; it doesn't fit the context of a completed action before another event in the past.
Option D:
Incorrect. "Was completed" uses the simple past, which does not indicate the completion before another past event as required by the sentence structure.
9.
What is the form of continuous modals?
A) The verb + be + the modal ending in-ing.
B) The modal + be + verb ending in-ing.
C) The modal + ing + be + the verb.
D) None of the above.
Show Answer
Explanations:
Continuous modal verbs are formed by combining a modal verb with the present participle (verb ending in -ing) of another verb. The correct form is
the modal + be + verb ending in -ing.
Option Analysis:
Option A:
Incorrect. The continuous form involves the present participle, not a gerund (-ing) with 'be'.
Option B:
Correct. This accurately describes how to form continuous modals.
Option C:
Incorrect. The order of words is wrong; it should be modal + be + verb -ing, not ing + be + the verb.
Option D:
Incorrect. Option B is correct.
10.
Why should you learn English?
A) She should learns English because it can help her to meet new people.
B) They should learn English because they can help them to meet new people.
C) I should learn English because it can help me to meet new people.
D) I learn English because it help me to meet new people.
Show Answer
Explanations:
Option C is correct because it uses the present tense "should" and first-person singular "I," which are appropriate for a personal statement about learning English. The sentence structure is grammatically accurate, making it suitable as an answer to why one should learn English.
Option Analysis:
Option A:
Incorrect; uses the third-person singular "she" instead of first-person "I."
Option B:
Incorrect; uses plural "they" and lacks personal connection.
Option C:
Correct; uses appropriate modal verb "should" and first-person "I."
Option D:
Incorrect; missing auxiliary verb "should," which is necessary for the modal construction.
11.
She ..... talk right now, she's driving.
A) Should.
B) Can't.
C) Must.
D) None of the above.
Show Answer
Explanations:
She can't talk right now, she's driving.
This sentence uses the continuous modal verb "can't" to express a prohibition due to an ongoing action (driving). The other options are incorrect because:
-
Option A:
"Should" implies a recommendation or obligation, which doesn't fit the context.
-
Option C:
"Must" suggests necessity, but driving doesn't require silence.
-
Option D:
"None of the above" is incorrect as "can't" fits perfectly.
Option Analysis:
Option A:
Should - Implies a recommendation or obligation.
Option B:
Can't - Correct, expresses prohibition due to an ongoing action (driving).
Option C:
Must - Suggests necessity, but driving doesn't require silence.
Option D:
None of the above - Incorrect as "can't" fits perfectly.
12.
The letter ..... (deliver) before the holiday started. (Past perfect)
A) Had been delivered.
B) Has delivered.
C) Was delivered.
D) Is delivered.
Show Answer
Explanations:
The sentence requires the use of the past perfect tense to indicate an action that was completed before another past action. The correct form is "had been delivered," which matches Option A.
Option Analysis:
Option A:
Correct. Uses past perfect tense indicating an action completed before another in the past.
Option B:
Incorrect. Uses present tense, not suitable for a past event that occurred before another past event.
Option C:
Incorrect. Uses simple past tense, which does not indicate the sequence of events as required.
Option D:
Incorrect. Uses present tense, not appropriate for describing an action in the past relative to another past action.
13.
Person A:What's all that noise?Person B:The neighbour's son is in a rock band .....
A) They could be practiced.
B) They must practice.
C) They can't be practicing.
D) They must be practicing.
Show Answer
Explanations:
The sentence "They must be practicing" uses the continuous form of the modal verb "must," which indicates a strong belief that an action is currently happening. This aligns with the context where Person B mentions the neighbor's son being in a rock band, suggesting ongoing practice.
Option Analysis:
Option A:
They could be practiced - Incorrect; "could" suggests possibility but not certainty.
Option B:
They must practice - Incorrect; this is the base form of the modal verb, not continuous.
Option C:
They can't be practicing - Incorrect; negation does not fit the context of strong belief in current action.
Option D:
They must be practicing - Correct; uses continuous form to indicate certainty about ongoing action.
14.
Which type of verbs are not used in the continuous form?
A) Action verbs.
B) Transitive verbs.
C) Intransitive verbs.
D) Non-action verbs.
Show Answer
Explanations:
Non-action verbs are not used in the continuous form because they do not describe actions that can be ongoing. Continuous forms are typically used with action verbs to indicate an activity happening at a particular time. Intransitive and transitive verbs, as well as other action verbs, can be used in both simple and continuous tenses.
Option Analysis:
Option A:
Action verbs can be used in the continuous form.
Option B:
Transitive verbs can also be used in the continuous form.
Option C:
Intransitive verbs can be used in the continuous form, especially when describing ongoing states or actions without a direct object.
Option D:
Correct. Non-action verbs do not describe actions that can occur continuously and thus are not typically used with continuous forms.
15.
What do you look like?
A) I am honest.
B) I like apples.
C) I am tall and slender.
D) I am like apples.
Show Answer
Explanations:
Option C is correct because "I am tall and slender" directly describes a physical appearance, which aligns with the question asked about what you look like. Continuous modal verbs are not relevant to describing physical appearance; they are used to express ongoing ability or permission.
Option Analysis:
Option A:
Irrelevant to physical appearance.
Option B:
Irrelevant to physical appearance.
Option C:
Correctly describes physical appearance.
Option D:
Irrelevant to physical appearance.
16.
The project ..... (complete) before the deadline. (Future perfect)
A) Will have completed.
B) Will be completed.
C) Will have been completed.
D) Has been completed.
Show Answer
Explanations:
The future perfect continuous tense is used to describe an action that will have been ongoing up to a point in the future. The correct form for this is "will have been + verb-ing". In the given sentence, "The project" is the subject and "completed" is the main verb. Therefore, the correct answer is
C) Will have been completed.
Option Analysis:
Option A:
Incorrect as it uses the future perfect simple tense instead of continuous form.
Option B:
Incorrect as it uses the future simple tense, which does not indicate completion by a point in the future.
Option C:
Correct as it uses the future perfect continuous tense to describe an action that will have been ongoing up to a point in the future.
Option D:
Incorrect as it uses the present perfect continuous tense, which is used for actions that started in the past and continue up to now or are still happening.
17.
The rules ..... (follow) by everyone. (modal verbs)
A) Might be follow.
B) Should following.
C) Must be followed.
D) Could follow.
Show Answer
Explanations:
The correct answer is
C) Must be followed.
This option uses the modal verb "must" to indicate a strong obligation, which fits well with the context of rules that everyone should adhere to. The passive voice "be followed" correctly structures the sentence.
Option Analysis:
Option A:
Incorrect as "might be follow" is not grammatically correct.
Option B:
Incorrect as "should following" lacks proper verb form and structure.
Option C:
Correct for using the strong obligation of a rule with passive voice.
Option D:
Incorrect as "could follow" implies possibility rather than necessity.
18.
By the time you arrive, the meal ..... (prepare). (Future perfect)
A) Is prepared.
B) Will be prepared.
C) Has been prepared.
D) Will have been prepared.
Show Answer
Explanations:
By the time you arrive, the meal will have been prepared correctly uses future perfect tense to indicate an action completed before a future time. This matches the context of the sentence where the meal is being prepared by someone else and will be finished by the time the speaker arrives.
Option Analysis:
Option A:
Is prepared - Simple present, incorrect tense.
Option B:
Will be prepared - Future simple, does not indicate completion by a future time.
Option C:
Has been prepared - Present perfect, refers to an action completed in the past, not at a future time.
Option D:
Will have been prepared - Future perfect, correct tense indicating completion before a future time.
19.
Which novel was he ..... (write) when he died so suddenly?
A) Write.
B) Wrote.
C) Writing.
D) None of the above.
Show Answer
Explanations:
The sentence requires a verb form that indicates the action of writing was in progress at the time of his sudden death. "Writing" (Option C) is the present participle, which correctly conveys an ongoing action when used with continuous modal verbs like "was" or "were."
Option Analysis:
Option A:
"Write" is in base form and does not indicate an ongoing action.
Option B:
"Wrote" indicates a completed action, which doesn't fit the context of an action in progress.
Option C:
"Writing" correctly conveys an ongoing action at the time of his death.
Option D:
"None of the above" is not applicable since "Writing" fits the requirement.
20.
All the tickets ..... (sell) before we reached the counter. (Past perfect)
A) Had been sold.
B) Had sold.
C) Were sold.
D) Was sold.
Show Answer
Explanations:
The sentence requires the use of the past perfect tense to indicate an action that occurred before another past action. "Had been sold" correctly conveys this sequence of events, as it shows that all tickets were already sold by the time they reached the counter.
Option Analysis:
Option A:
Correct. Uses past perfect tense indicating a completed action before another past event.
Option B:
Incorrect. Past simple does not indicate sequence of events in the past.
Option C:
Incorrect. Simple past does not indicate sequence of events in the past.
Option D:
Incorrect. Simple past does not indicate sequence of events in the past.
21.
They aren't here yet and it's getting late. They .....
A) Must come.
B) Mightn't be coming.
C) Might not be coming.
D) Couldn't be coming.
Show Answer
Explanations:
The sentence "They aren't here yet and it's getting late. They might not be coming." uses the modal verb "might" in its negative form, indicating a possibility that is uncertain. This aligns with option C, which correctly conveys an uncertainty about whether they will arrive.
Option Analysis:
Option A:
Incorrect as it suggests certainty ("Must come") which contradicts the context of uncertainty.
Option B:
Incorrect as "Mightn't be coming" is less common and sounds awkward in this context compared to "might not be coming."
Option C:
Correct, uses modal verb "might" in negative form indicating an uncertain possibility.
Option D:
Incorrect as it suggests impossibility ("Couldn't be coming") which contradicts the context of uncertainty.
22.
Which verb type can be used in the continuous form?
A) Verbs that convey feelings.
B) Verbs of the senses.
C) Verbs of ownership.
D) Action verbs.
Show Answer
Explanations:
Continuous forms are used with action verbs to indicate an ongoing activity at a specific time in the past, present, or future. Verbs of feelings (Option A), senses (Option B), and ownership (Option C) do not typically use continuous forms as they describe states rather than actions.
Option Analysis:
Option A:
Verbs that convey feelings are generally in simple present tense or other tenses, not continuous.
Option B:
Verbs of the senses can be used with continuous forms but are not as common as action verbs for this purpose.
Option C:
Verbs of ownership do not use continuous forms.
Option D:
Action verbs, such as "run," "eat," or "write," can be used in the continuous form to indicate an ongoing action. This is correct.
23.
The painting ..... (sell) before the auction ended. (Past perfect)
A) Had sold.
B) Was sold.
C) Has been sold.
D) Had been sold.
Show Answer
Explanations:
The sentence requires the use of a past perfect continuous tense to indicate an action that was completed before another past action. "Had been sold" correctly conveys this meaning, as it indicates the painting had already undergone the process of being sold by the time the auction ended.
Option Analysis:
Option A:
"Had sold" is incorrect because it uses a simple past perfect form, which does not indicate an ongoing state.
Option B:
"Was sold" is in the simple past tense and does not convey the idea of something that had already happened before another action in the past.
Option C:
"Has been sold" is in the present perfect continuous tense, which refers to an action that started in the past and continues up to now. It is therefore incorrect for this context.
Option D:
"Had been sold" correctly uses a past perfect continuous form, indicating the painting had already undergone the process of being sold by the time the auction ended. This makes it the correct choice.
24.
Choose the right verb form to complete the sentence:Mariana ..... (jump) over the fence and ..... (escape) from home last night.
A) Jumpt-escaped.
B) Jumps-escapes.
C) Jumping-escaping.
D) Jumped-escaped.
Show Answer
Explanations:
The correct answer is
D) Jumped-escaped.
This option uses the past tense of the verb "jump" (jumped) to describe a completed action in the past, and the past tense of the verb "escape" (escaped) to indicate that Mariana successfully left her home last night. The sentence structure is appropriate for describing two distinct actions: jumping over the fence and then escaping from home.
Option Analysis:
Option A:
Incorrect as it uses present tense forms which do not fit in a past context.
Option B:
Incorrect as both verbs are in present tense, not suitable for describing completed actions in the past.
Option C:
Incorrect as "jumping-escaping" suggests ongoing actions rather than completed ones.
Option D:
Correct as it uses appropriate past tense forms to describe completed actions.
25.
I ..... take penicillin. I'm allergic.
A) Should.
B) Can't.
C) Must.
D) None of the above.
Show Answer
Explanations:
The sentence "I can't take penicillin. I'm allergic." uses the modal verb 'can't', which is a continuous modal verb indicating an inability due to a permanent condition (allergy in this case). This aligns with the correct answer B, as it properly conveys that taking penicillin is not possible for the speaker.
Option Analysis:
Option A:
Should - Incorrect. 'Should' implies a recommendation or obligation, which does not fit the context of an allergy.
Option B:
Can't - Correct. 'Can't' is used to express inability due to a permanent condition, fitting the scenario of being allergic.
Option C:
Must - Incorrect. 'Must' implies necessity or obligation, which does not fit the context of an allergy.
Option D:
None of the above - Incorrect. Option B is correct.
26.
It ..... raining in Japan right now.
A) Must rain.
B) Have to.
C) Could.
D) Might be.
Show Answer
Explanations:
The sentence "It might be raining in Japan right now" uses the modal verb "might," which indicates a possibility or uncertainty about the current weather condition. This aligns with option D, as it conveys that rain is a possible but not certain occurrence.
Option Analysis:
Option A:
Incorrect. "Must rain" implies certainty, which does not match the uncertain tone of the sentence.
Option B:
Incorrect. "Have to" suggests necessity rather than possibility or uncertainty.
Option C:
Incorrect. "Could" also indicates a possibility but is less formal and precise in this context compared to "might." However, both could be correct depending on the formality level required.
Option D:
Correct. "Might be" accurately reflects the uncertain nature of the statement about current weather conditions.
27.
Use past simple and past continuous to complete the sentences:My mom ..... (drink) a cup of tea at 7:00 o'clock when my sister ..... (come) home.
A) Was dranking-camed.
B) Was drinking-came.
C) Were drinking-comed.
D) Drank-was coming.
Show Answer
Explanations:
The correct answer is
B) Was drinking-came.
In this sentence, "was drinking" indicates an action that was ongoing in the past at a specific time (7:00 o'clock), while "came" shows another action that started during or after the first action. This structure correctly uses the past continuous tense for the ongoing action and the simple past tense for the completed action.
Option Analysis:
Option A:
Incorrect because "was dranking" is misspelled, and "camed" is not a proper form of the verb.
Option B:
Correct as explained above.
Option C:
Incorrect for the same reasons as Option A; "were drinking" should be singular with "my mom," and "comed" is incorrect.
Option D:
Incorrect because it reverses the tense, making the ongoing action in the past simple while the completed action uses the past continuous.
28.
Several reports ..... (submit) already this morning. (Present perfect)
A) Have been submitted.
B) Were submitted.
C) Are submitted.
D) Have submitted.
Show Answer
Explanations:
The sentence "Several reports have been submitted already this morning" uses the present perfect continuous tense, which is formed with "have/has + been + verb+ing". This structure indicates an action that started in the past and continues up to now. In this context, it suggests that the reports were being submitted at various points throughout the morning until they were all completed.
Option Analysis:
Option A:
Correct. "Have been submitted" matches the present perfect continuous tense.
Option B:
Incorrect. "Were submitted" is in the simple past tense, which does not fit the context of an ongoing action up to now.
Option C:
Incorrect. "Are submitted" is in the simple present tense and does not indicate a completed action involving a period that started in the past.
Option D:
Incorrect. "Have submitted" is in the present perfect tense, which indicates a completed action but lacks the continuous aspect required by the context.
29.
The assignment ..... (finish) just in time. (Present perfect)
A) Has finished.
B) Has been finished.
C) Was finished.
D) Is being finished.
Show Answer
Explanations:
The sentence "The assignment has been finished just in time" uses the present perfect continuous tense, which is formed with "has/have been + verb+ing". This tense emphasizes an action that started in the past and continued up to a point in the present. In this context, it indicates that the assignment was being worked on over a period of time until it was completed just in time.
Option Analysis:
Option A:
"Has finished" - This is incorrect because it uses simple present perfect instead of continuous.
Option B:
"Has been finished" - This is correct as it uses the present perfect continuous tense, indicating an action that started in the past and continued up to a point in the present.
Option C:
"Was finished" - This is incorrect because it uses simple past instead of present perfect continuous.
Option D:
"Is being finished" - This is incorrect as it uses present continuous, which does not fit the context of an action completed in the past.
30.

D) Possibility.
Show Answer
Explanations:
The modal 'might' in the sentence 'It might be raining in Japan right now.' indicates a possibility, not certainty. It suggests that there is a chance of rain but it is not certain.
Option Analysis:
Option A:
Impossibility - Incorrect. 'Might' does not suggest impossibility.
Option B:
Necessity - Incorrect. 'Might' does not imply that rain is necessary or required.
Option C:
Certainty - Incorrect. 'Might' suggests uncertainty, not certainty.
Option D:
Possibility - Correct. 'Might' indicates a possibility of the action (raining) occurring.
Frequently Asked Questions
What are continuous modal verbs?
Continuous modal verbs combine the concept of modality with a continuous aspect, indicating both permission or necessity and ongoing action. Examples include "must be" or "can be," where the verb expresses an ongoing state rather than a one-time occurrence.
How are continuous modal verbs used in prohibition?
Continuous modal verbs can be used to express prohibitions, such as "must not be" or "should not be," emphasizing that an ongoing action is forbidden. This construction highlights the current and persistent nature of the prohibition.
Can continuous modal verbs be used in passive voice?
Yes, continuous modal verbs can be employed in passive constructions. For example, "It must be being discussed" uses the present continuous tense with a modal verb in its passive form to indicate an ongoing state of something that is happening to or by someone else.
What are some common tenses associated with continuous modal verbs?
Continuous modal verbs can be used in various tenses, such as the present perfect continuous ("has been being"), past perfect continuous ("had been being"), and future perfect continuous ("will have been being"). These tenses help describe ongoing actions that are related to modality.
How do continuous modal verbs differ from simple present tense?
Continuous modal verbs often indicate an ongoing or habitual state of permission, necessity, or possibility, whereas the simple present tense typically describes general truths or repeated actions. For example, "You must be studying" suggests a current requirement, while "You study regularly" indicates a habit.
