1.
I come from a city ..... in the southern part of the country.
A) Locates.
B) Located.
C) Locating.
D) Which located.
Show Answer
Explanations:
The correct answer is
B) Located.
The sentence requires an infinitive clause to describe the location of the city, which should be in the past participle form "located" to function as a participial phrase modifying "city." This structure provides additional information about the city's position within the country.
Option Analysis:
Option A:
Incorrect. "Locates" is not in the correct form for describing a location.
Option B:
Correct. "Located" functions as an adjective to describe the city's position.
Option C:
Incorrect. "Locating" is a gerund and does not fit grammatically here.
Option D:
Incorrect. This option is not relevant to the sentence structure needed for describing location.
2.
The boy ..... in the accident was taken to hospital.
A) Injured.
B) Injuring.
C) Have injured.
D) Being injured.
Show Answer
Explanations:
The correct answer is
A) Injured.
The sentence requires an infinitive clause to describe the state of the boy, which is "to be injured." Since the boy has already been taken to the hospital due to being injured in the accident, using the past participle "injured" as a passive form fits grammatically and contextually.
Option Analysis:
Option A:
Correct. Uses the past participle "injured" which is appropriate for describing the state of the boy.
Option B:
Incorrect. Present participle "injuring" does not fit as it implies an ongoing action, not a completed one.
Option C:
Incorrect. This option uses a verb form that is not suitable for describing the state of the boy in this context.
Option D:
Incorrect. "Being injured" would imply an ongoing state and does not fit the passive voice required by the sentence structure.
3.
According to the latest issue of the journal of American Medical Association, ..... can reduce the risk of sudden cardiac death in men.
A) Fish being eaten every week.
B) To eat weekly fish.
C) Fish to he eaten weekly.
D) Eating fish just once a week.
E) If we eat fish once a week.
Show Answer
Explanations:
Option D, "Eating fish just once a week," is the correct answer because it correctly uses the infinitive form "eating" to introduce the clause and maintains proper subject-verb agreement with "can reduce." The phrase "just once a week" accurately conveys the frequency without altering the infinitive structure.
Option Analysis:
Option A:
Incorrect. "Fish being eaten every week" uses a gerund instead of an infinitive.
Option B:
Incorrect. "To eat weekly fish" is grammatically incorrect and does not use the proper infinitive form.
Option C:
Incorrect. "Fish to he eaten weekly" is awkward and incorrectly structured, using a gerund with an unnecessary pronoun.
Option D:
Correct. "Eating fish just once a week" uses the correct infinitive form and proper frequency phrase.
Option E:
Incorrect. "If we eat fish once a week" is a conditional clause, not an infinitive clause.
4.
Scientists ..... on the site found many ancient tools, tombs and pottery, and made some important archaeological discoveries.
A) Worked.
B) To work.
C) Working.
D) To be working.
Show Answer
Explanations:
"Scientists working on the site found many ancient tools, tombs and pottery, and made some important archaeological discoveries."
The correct answer is
C) Working.
This option uses an infinitive clause "working on the site" as a participial phrase that modifies "Scientists," indicating their ongoing activity at the location where the discoveries were made. The other options do not fit grammatically or semantically in this context.
Option Analysis:
Option A:
Incorrect; it uses a simple past tense which does not fit the context of an ongoing action.
Option B:
Incorrect; it uses a gerund form which is not appropriate for modifying "Scientists" in this sentence structure.
Option C:
Correct; it uses the present participle "working" as a participial phrase to describe the scientists' ongoing activity at the site.
Option D:
Incorrect; it uses an infinitive form with "to be," which is not suitable for this context.
5.
Almaida is looking for his wallet, she can't find it, She ..... her key since an hour ago. (lose)
A) Will lost.
B) Has lost.
C) Have lost.
D) Lost.
E) Is loosing.
Show Answer
Explanations:
The sentence requires a past perfect continuous tense to indicate an action that started in the past and continued up until another point in the past (in this case, the present). "Has lost" is the correct form of the past perfect continuous tense for the subject "she." It accurately conveys that she began losing her key at some time in the past and has not found it since then.
Option Analysis:
Option A:
Incorrect. Future tense does not fit the context.
Option B:
Correct. Past perfect continuous tense fits the context perfectly.
Option C:
Incorrect. Present perfect does not indicate a continuous action in the past.
Option D:
Incorrect. Simple past does not fit the context of an ongoing action up to the present.
Option E:
Incorrect. Present continuous does not fit the context of an event that started and ended in the past.
6.
..... is crucial to investigate more to do a good project
A) They.
B) It.
C) I.
D) He.
Show Answer
Explanations:
"It" is the correct answer because it functions as the subject of the infinitive clause "to investigate more to do a good project." The infinitive phrase "to investigate more" acts as a noun here, referring back to "it," making "it" the appropriate choice.
Option Analysis:
Option A:
They - Incorrect. "They" is plural and does not fit grammatically in this context.
Option B:
It - Correct. "It" serves as the subject of the infinitive clause, referring to the investigation or project.
Option C:
I - Incorrect. "I" is singular and does not fit grammatically in this context.
Option D:
He - Incorrect. "He" is singular and does not fit grammatically in this context.
7.
Sarah crashed into my car last night, .....
A) That was really annoying.
B) It was really annoying.
C) Which was really annoying.
D) Was really annoying.
Show Answer
Explanations:
Option C is correct because it uses a relative pronoun "which" to introduce the infinitive clause, making the sentence grammatically complete and clear in meaning. The use of "which" here connects the main clause with additional information about Sarah's action.
Option Analysis:
Option A:
This option starts with a subject pronoun "That," which is incorrect as it does not properly introduce the infinitive clause.
Option B:
This option lacks the relative pronoun "which" and thus does not connect the main clause effectively to the additional information about Sarah's action.
Option D:
This option is a question form, which is inappropriate in this context as it asks for something rather than stating a fact or providing an explanation.
8.
The house which was built over 150 years must be pulled down
A) The house built over 150 years must be pulled down.
B) The house was built over 150 years must be pulled down.
C) The house buidling over 150 years must be pulled down.
D) None of above.
Show Answer
Explanations:
The correct answer is
A) The house built over 150 years must be pulled down.
This option uses the past participle "built" as part of an infinitive clause, which correctly modifies "house." The other options are incorrect because they either use a different form of the verb (Option B and C), or both have grammatical errors that make them ungrammatical (Option D).
Option Analysis:
Option A:
Correct. Uses past participle "built" in an infinitive clause.
Option B:
Incorrect. Uses the wrong form of the verb "was built," which disrupts the infinitive structure.
Option C:
Incorrect. Misspells "built" as "buidling," disrupting the infinitive structure and grammatical correctness.
Option D:
Incorrect. States "None of above," but A is correct, making this option wrong.
9.
One way to reduce government corruption
A) Is provide education to all children.
B) Are to provide education to all children.
C) Is provides education to all children.
D) Is to provide education to all children.
Show Answer
Explanations:
The correct answer is
D) Is to provide education to all children.
This option uses the infinitive clause "to provide education to all children" correctly after the verb "is." In English, when using an infinitive clause as a subject complement following "is," "are," or "were," the infinitive begins with "to" and is followed by the base form of the verb.
Option Analysis:
Option A:
Incorrect; it lacks the necessary "to" before "provide."
Option B:
Incorrect; it repeats "are," which is redundant.
Option C:
Incorrect; it incorrectly uses "provides" instead of "to provide."
Option D:
Correct; it properly uses the infinitive clause starting with "to provide."
10.
Which sentence is wrong?
A) It's hard to understand Carol's handwriting.
B) Understanding Carol's handwriting is hard.
C) To understand Carol's handwriting is hard.
D) It's hard understanding Carol's handwriting.
Show Answer
Explanations:
Option A is grammatically correct and uses a subject-verb-object structure, making it the proper way to express the idea.
Option B correctly uses "understanding" as an infinitive clause acting as the subject of the sentence.
Option C also uses an infinitive clause properly by starting with "To understand," which functions as the subject complement.
Option D is incorrect because it omits the auxiliary verb "is" before "hard," making the infinitive phrase "understanding" a direct object without proper linking.
Option Analysis:
Option A:
Correct. Subject-verb-object structure.
Option B:
Correct. Infinitive clause as subject.
Option C:
Correct. Infinitive clause as subject complement.
Option D:
Incorrect. Missing auxiliary verb "is" before "hard."
11.
It's a good idea ..... medical attention if the injury is severe.
A) To get.
B) Getting.
C) To got.
D) Get.
Show Answer
Explanations:
The infinitive form "to get" is used after "it's a good idea," which introduces an infinitive clause. This structure indicates a recommendation or suggestion, making Option A the correct choice.
Option Analysis:
Option A:
Correct. The infinitive "to get" properly follows "it's a good idea."
Option B:
Incorrect. "Getting" is a gerund, not an infinitive and does not fit the sentence structure.
Option C:
Incorrect. "To got" is grammatically incorrect; "got" is past tense of "get," not part of the infinitive form.
Option D:
Incorrect. "Get" alone does not fit as it lacks the necessary infinitive structure introduced by "it's a good idea."
12.
A man ..... by everyone was killed last week in an accident.
A) Respects.
B) Respect.
C) Respeting.
D) Respected.
Show Answer
Explanations:
The sentence requires an infinitive clause introduced by "to be" as the subject complement, which is why "Respected" (Option D) is correct. The structure "was respected by everyone" indicates that the man was killed because he was respected by everyone.
Option Analysis:
Option A:
"Respects" does not fit grammatically as it is in present tense and doesn't match the past tense of the sentence.
Option B:
"Respect" lacks the infinitive form needed for the structure.
Option C:
"Respeting" is a misspelling and not grammatically correct in English.
Option D:
"Respected" correctly forms an infinitive clause with "to be" implied, fitting the sentence structure.
13.
Here are some of the things ..... when visiting a heritage site.
A) Avoided.
B) Avoiding.
C) To avoid.
D) Avoid.
Show Answer
Explanations:
The infinitive clause "To avoid" is the correct answer because it properly introduces a purpose for the actions that follow in the sentence. In English, infinitives often begin with "to" and are used to express purposes or reasons. Here, "To avoid" sets up what should be done when visiting a heritage site.
Option Analysis:
Option A:
"Avoided" is in the past tense and does not introduce a purpose clause.
Option B:
"Avoiding" is a gerund form, which cannot introduce an infinitive clause.
Option C:
"To avoid" correctly introduces the purpose of actions when visiting a heritage site.
Option D:
"Avoid" lacks the necessary "to" and does not function as a complete infinitive form.
14.
They live in a house ..... in 1890.
A) Was built.
B) Build.
C) That built.
D) Built.
Show Answer
Explanations:
The correct answer is
D) Built.
In this sentence, the infinitive clause "in a house built in 1890" functions as an adjective modifying "house." The past participle "built" correctly describes the state of the house without requiring an auxiliary verb like "was" or "is."
Option Analysis:
Option A:
Incorrect. Using "Was built" would require a subject and auxiliary verb, making it a full clause rather than an infinitive phrase.
Option B:
Incorrect. "Build" is the base form of the verb and does not fit grammatically in this context as an adjective modifying "house."
Option C:
Incorrect. "That built" would imply a relative clause, which is not appropriate here.
Option D:
Correct. "Built" functions as the past participle form of the verb in this infinitive phrase, describing the state of the house.
15.
The best way ..... London is by taking a guided tour.
A) In which you see.
B) To see.
C) Seeing.
D) Seen.
Show Answer
Explanations:
The infinitive clause "To see" is the correct answer because it functions as an infinitival purpose clause modifying "the best way." In English, when we want to express a purpose or intention for doing something, we use the infinitive form of the verb. Here, "to see" indicates the purpose of taking a guided tour.
Option Analysis:
Option A:
"In which you see" is a relative clause and does not fit grammatically in this context.
Option B:
"To see" correctly functions as an infinitive purpose clause, making it the best choice.
Option C:
"Seeing" is a gerund and cannot be used to express purpose here.
Option D:
"Seen" is a past participle and does not fit grammatically in this context.
16.
That's the church ..... my grandparents were married.
A) In where.
B) Which.
C) In that.
D) In which.
Show Answer
Explanations:
The correct answer is
D) In which.
The sentence "That's the church in which my grandparents were married." uses an infinitive clause introduced by "in which" to specify where the event of marriage took place. This construction indicates a location where something happened.
Option Analysis:
Option A:
"In where" is not grammatically correct.
Option B:
"Which" alone would imply a question or a choice, not a specific location.
Option C:
"In that" does not fit the context of specifying a location for an event.
Option D:
"In which" correctly introduces the infinitive clause to specify where the marriage took place.
17.
Mike and Jill, ..... had ever eaten asparagus before, thought it was delicious.
A) Neither of who.
B) Both of whom.
C) Neither of whom.
D) Whom.
Show Answer
Explanations:
The correct answer is
C) Neither of whom.
This option correctly uses the infinitive clause "had ever eaten" with "neither," which indicates that neither Mike nor Jill had any experience with asparagus before, but they both found it delicious. The phrase "of whom" properly refers to both individuals.
Option Analysis:
Option A:
Incorrect because "Neither of who" is not a proper construction in English.
Option B:
Incorrect as "Both of whom" would imply that both had experience with asparagus, which contradicts the sentence structure and meaning.
Option C:
Correct for reasons explained above.
Option D:
Incorrect because "Whom" alone does not properly introduce an infinitive clause in this context.
18.
I was the only one who realized him
A) I was the only one to realize him.
B) I was the only one realized him.
C) I was the only one realizing him.
D) None of above.
Show Answer
Explanations:
The correct answer is
A) I was the only one to realize him.
This sentence uses an infinitive clause "to realize him" as a complement, which correctly modifies the subject "I." The infinitive phrase functions as an adverbial of purpose or result.
Option Analysis:
Option A:
Correct. Uses "to realize him," an infinitive clause functioning as a complement.
Option B:
Incorrect. "Realized" is in the past tense, not an infinitive and does not function correctly here.
Option C:
Incorrect. "Realizing" is a gerund, which cannot be used to modify the subject as it stands.
Option D:
Incorrect. At least one option (A) is correct.
19.
The boy ..... the piano is Ben.
A) Is playing.
B) Played.
C) Who playing.
D) Playing.
Show Answer
Explanations:
The correct answer is
D) Playing.
This option correctly uses the infinitive clause "playing" to describe Ben's action, which fits naturally in the sentence structure provided.
Option Analysis:
Option A:
Is playing. - Incorrect as it should be an infinitive form without 'to'.
Option B:
Played. - Incorrect as past tense does not fit the context of describing current action.
Option C:
Who playing. - Incorrect grammatical structure, missing 'is' and 'the piano'.
Option D:
Playing. - Correct infinitive form used to describe Ben's ongoing action.
20.
..... a small company ..... profitable, it should have a good marketing plan.
A) In order / for.
B) To be / for.
C) For / in order.
D) For / to be.
Show Answer
Explanations:
The sentence requires a preposition "for" to introduce the purpose of having a good marketing plan, which is indicated by "in order to be profitable." The phrase "to be profitable" is an infinitive clause functioning as the object of the preposition "for."
Option Analysis:
Option A:
In order / for. - Incorrect because it uses "In order" instead of a preposition.
Option B:
To be / for. - Incorrect because it lacks the necessary preposition "for."
Option C:
For / in order. - Incorrect because it uses "in order" instead of "to be" and "for."
Option D:
For / to be. - Correct as it properly introduces the purpose with "for" and uses the infinitive "to be" for the desired outcome.
21.
The team has had a disastrous season so far, ..... only three of its last sixteen games.
A) Which has won.
B) Having won.
C) To win.
D) While winning.
Show Answer
Explanations:
"Having won" is the correct answer because it uses a present perfect participle clause to indicate an action that occurred before another action (the disastrous season). This structure effectively conveys that despite winning only three of its last sixteen games, the team still had a good record or performance in other games.
Option Analysis:
Option A:
"Which has won" is incorrect because it uses an unnecessary relative clause and does not fit grammatically with the sentence.
Option B:
"Having won" correctly uses a present perfect participle to show that winning occurred before the disastrous season, making it the right choice.
Option C:
"To win" is incorrect because it uses an infinitive form which does not fit the context of describing past actions.
Option D:
"While winning" suggests simultaneous action and does not fit the sequence implied by the sentence structure.
22.
It's important ..... after sustaining an injury.
A) Rest.
B) To rest.
C) Rested.
D) Resting.
Show Answer
Explanations:
The infinitive clause "To rest" is the correct answer because it correctly functions as an important element after the verb "It's important." In English, when expressing necessity or importance, using the infinitive form (to + base verb) is appropriate. This structure emphasizes that resting is what should be done.
Option Analysis:
Option A:
"Rest" alone does not fit grammatically in this context.
Option B:
"To rest" correctly uses the infinitive form to express importance.
Option C:
"Rested" is a past participle and does not fit here as it doesn't indicate necessity or importance.
Option D:
"Resting" is a gerund and would imply an ongoing action, which is not the intended meaning in this sentence.
23.
Most houses in Hoi An are of ..... architecture dating fron the 17th to the 19th century.
A) Tradition.
B) Customary.
C) Traditional.
D) Ancient.
Show Answer
Explanations:
The correct answer is
D) Ancient.
The term "ancient" refers to something that dates back a long time, which fits the description of houses from the 17th to the 19th century. However, it's important to note that "traditional" (C) would also be a correct choice as it implies the style or method has been passed down over generations, aligning with historical architecture.
Option Analysis:
Option A:
Tradition refers to the passing of customs and beliefs from generation to generation but does not specifically indicate the age of the houses.
Option B:
Customary means following or adhering to a custom, which is not directly related to the architectural dating.
Option C:
Traditional implies the style has been passed down over time but does not specify the historical period as accurately as "ancient" or "traditional" would in this context.
Option D:
Ancient correctly indicates that the houses date from a long time ago, fitting the 17th to 19th century timeframe well.
24.
Tiago and Toni ..... to Jakarta since yesterday.
A) Went.
B) Has gone.
C) Is going.
D) Have gone.
E) Will go.
Show Answer
Explanations:
The sentence "Tiago and Toni have gone to Jakarta since yesterday" uses the present perfect tense, which is used to describe an action that started in the past but continues up to now. The phrase "since yesterday" indicates a period starting from the past that extends to the present.
Option Analysis:
Option A:
Went - Simple past tense; does not indicate ongoing effect or connection to current time.
Option B:
Has gone - Correct form, indicating an action started in the past and continuing up to now.
Option C:
Is going - Present continuous tense; describes an action happening at present, not a completed action with ongoing effect.
Option D:
Have gone - Correct form for plural subjects (Tiago and Toni) indicating an action started in the past and continuing up to now.
Option E:
Will go - Future tense; describes an action that will happen, not one that has already occurred and continues.
25.
Andy and Karen, ..... are unemployed, have offered to look after my house next summer.
A) Both of whom.
B) Who are both.
C) Both of who.
D) Both two.
Show Answer
Explanations:
Both of whom is the correct answer because it properly introduces an infinitive clause that modifies "Andy and Karen." The phrase "both of whom" correctly refers to two people, Andy and Karen, who are unemployed and have offered to look after your house next summer.
Option Analysis:
Option A:
Correct. Introduces an infinitive clause with "are unemployed" following.
Option B:
Incorrect. Who are both is not a proper construction for introducing the clause.
Option C:
Incorrect. Both of who is grammatically incorrect.
Option D:
Incorrect. Both two is redundant and not grammatically correct in this context.
26.
The woman ..... next door is a famous singer.
A) That living.
B) Lives.
C) Who live.
D) Living.
Show Answer
Explanations:
The correct answer is
D) Living.
This option correctly uses the present participle "living" to describe the woman next door, indicating that she resides there. The sentence structure implies a descriptive clause where "living next door" functions as an adjective modifying "the woman," which is more concise and grammatically appropriate than using a relative pronoun like "that" or "who."
Option Analysis:
Option A:
Incorrect. Using "That living" does not form a proper clause and lacks clarity.
Option B:
Incorrect. "Lives" is in the simple present tense, which doesn't fit the descriptive nature of the sentence.
Option C:
Incorrect. "Who live" implies more than one person, which contradicts the singular subject "the woman."
Option D:
Correct. "Living" is a present participle that properly modifies "the woman," providing a concise and clear description.
27.
Do you know the woman ..... toward us?
A) Who come.
B) Coming.
C) Comes.
D) Who coming.
Show Answer
Explanations:
Option B "Coming" is correct because it properly introduces the infinitive clause in this sentence. The phrase "toward us" acts as a prepositional phrase modifying "woman," and "coming" functions as an adjective describing her action or state.
Option Analysis:
Option A:
Incorrect; "Who come" is not the correct form for an infinitive clause.
Option B:
Correct; "Coming" properly introduces the infinitive clause.
Option C:
Incorrect; "Comes" is a verb and does not fit grammatically in this context.
Option D:
Incorrect; "Who coming" is not the correct form for an infinitive clause.
28.
You can definitely wear ..... you like.
A) Whatever dress.
B) Any of dress.
C) Whichever dress.
D) Which dress.
Show Answer
Explanations:
"Whichever dress" is the correct answer because it introduces an infinitive clause that allows for a choice between multiple dresses, fitting the context of the sentence where you have the freedom to choose any dress you like.
Option Analysis:
Option A:
"Whatever dress" does not fit grammatically in this context as it lacks the necessary structure to introduce an infinitive clause.
Option B:
"Any of dress" is incorrect because "any of" requires a plural noun and does not properly introduce an infinitive clause.
Option C:
"Whichever dress" correctly introduces the choice between multiple dresses, fitting the context of making a selection based on preference or suitability.
Option D:
"Which dress" is interrogative and does not fit in this declarative sentence structure to express a choice.
29.
Which of the following sentences uses an infinitive clause with impersonal "it" related to injuries correctly?
A) It's important to take care of your injuries.
B) It's better to not to ice a sprained ankle.
C) It was hurting to lift weights yesterday.
D) It's hurting to lift weights yesterday.
Show Answer
Explanations:
Option A correctly uses an infinitive clause with the impersonal "it" related to injuries. The sentence structure is proper, and it conveys that taking care of one's injuries is important in a general sense.
Option Analysis:
Option A:
Correct. Uses "It's + adjective + infinitive clause." Proper grammar.
Option B:
Incorrect. The double negative ("not to") makes the sentence grammatically incorrect and confusing.
Option C:
Incorrect. "Hurting" is a present participle, not an infinitive clause with impersonal "it."
Option D:
Incorrect. "Hurting" is a present participle, not an infinitive clause with impersonal "it," and the sentence structure is incorrect.
30.
Despite criticisms from political opponents, the new president continues his ..... abroad to appeal to foreign countries to invest in Indonesia.
A) To travel.
B) Traveled.
C) Traveling.
D) To he traveled.
E) He traveling.
Show Answer
Explanations:
The sentence requires an -ing form to function as a gerund, which acts as the object of the preposition "to." The correct answer is
C) Traveling.
This infinitive clause "to traveling" functions as the direct object of the verb "continues," making it the most appropriate choice.
Option Analysis:
Option A:
Incorrect. "To travel" is not a gerund and cannot function as the object of a preposition in this context.
Option B:
Incorrect. "Traveled" is a past tense verb, which does not fit grammatically here.
Option C:
Correct. "Traveling" is an -ing form that functions as the object of the preposition "to."
Option D:
Incorrect. "To he traveled" is grammatically incorrect and does not make sense in this context.
Option E:
Incorrect. "He traveling" is a fragment and does not fit grammatically here.
Frequently Asked Questions
What are infinitive clauses, and how do they function in sentences?
Infinitive clauses begin with the word "to" followed by a verb. They can act as subjects, objects of prepositions, or subject complements, among other functions. For example, in "To walk is good for health," "To walk" serves as the subject.
Can infinitive clauses express purpose?
Yes, infinitive clauses can indicate purpose. For instance, in "I went to the store to buy milk," the clause "to buy milk" expresses why you went to the store.
How do infinitive clauses modify nouns?
Infinitive clauses can modify nouns by providing additional information about them. For example, in "The decision to resign was difficult," the clause "to resign" modifies "decision."
What is an impersonal "it" used for in infinitive clauses?
An impersonal "it" can be used as the subject of an infinitive clause to avoid repetition. For example, instead of saying "It is important to study hard," one might say "To study hard is important."
How do past perfect continuous tense infinitive clauses differ from other tenses?
Past perfect continuous tense in infinitive clauses, such as "to have been studying," indicates an action that was ongoing up to a certain point in the past. This is distinct from simple past ("to study") or present perfect continuous ("to have been studying").
