1.
We hope to ..... the entire living room before the family reunion next month.
A) Have run.
B) Aim.
C) Have redecorated.
D) Hopes.
Show Answer
Explanations:
"Have redecorated" is the correct answer because it uses the perfect infinitive form, which indicates an action that has been completed and its effects are still relevant now. In this context, redecorating the living room before a family reunion suggests that the action of redecorating is finished and the results will be seen during the reunion.
Option Analysis:
Option A:
"Have run" does not fit grammatically or contextually. Running cannot be used to describe decorating an entire living room.
Option B:
"Aim" is a verb and does not form the perfect infinitive with 'to'.
Option C:
"Have redecorated" correctly uses the perfect infinitive, indicating a completed action with ongoing results.
Option D:
"Hopes" is a present tense verb and does not form the perfect infinitive with 'to'.
2.
The fridge is empty! You ..... grocery shopping like you said.
A) Must have gone.
B) Can't have gone.
C) Must go.
D) None of the above.
Show Answer
Explanations:
The sentence "The fridge is empty! You can't have gone grocery shopping like you said." uses the perfect infinitive construction "can't have gone" to express a strong belief that something did not happen in the past, despite an expectation or previous indication. This structure implies a contradiction between what was expected and the current situation.
Option Analysis:
Option A:
Must have gone - Incorrect as it suggests certainty of going, contradicting the fridge's emptiness.
Option B:
Can't have gone - Correct as it expresses a strong belief that grocery shopping did not occur despite expectations.
Option C:
Must go - Incorrect as it implies future action, not addressing the past situation of the fridge's emptiness.
Option D:
None of the above - Incorrect as Option B is correct.
3.
Which sentence demonstrates the correct use of a perfect infinitive after a modal verb expressing past possibility?
A) They might to have finished the project by now.
B) They might have finished the project by now.
C) They might had finished the project by now.
D) They might finish the project by now.
Show Answer
Explanations:
The correct answer is
B) They might have finished the project by now.
This sentence correctly uses a perfect infinitive after the modal verb "might" to express past possibility. The structure "modal verb + have + past participle" (in this case, "have finished") is necessary for forming the perfect infinitive in English.
Option Analysis:
Option A:
Incorrect; "to have" should not be used with a modal verb.
Option B:
Correct; uses the proper structure for a perfect infinitive after a modal verb expressing past possibility.
Option C:
Incorrect; "had" is unnecessary and changes the tense to simple past, not perfect.
Option D:

4.
They look very happy in the photos. They ..... their vacation.
A) Must have enjoyed.
B) Can't have enjoyed.
C) Must be enjoying.
D) None of the above.
Show Answer
Explanations:
The sentence "They look very happy in the photos. They must have enjoyed their vacation." uses the perfect infinitive "must have enjoyed" to express a strong inference about a past event based on current evidence (their happiness in the photos). This construction is appropriate here because it indicates that the speakers are making an educated guess or deduction about what happened in the past.
Option Analysis:
Option A:
Correct. Uses perfect infinitive to infer a past event based on current evidence.
Option B:
Incorrect. "Can't have enjoyed" suggests an impossibility, which is not indicated by the context of the sentence.
Option C:
Incorrect. "Must be enjoying" refers to a present state, but the context is about a past vacation.

Incorrect. There is a correct answer among the options provided.

Option Analysis:
Option A:
Correct. Uses "having finished," a perfect participle.
Option B:
Incorrect. Uses present participle "finishing" without "having."
Option C:
Incorrect. Uses past participle "finished" without "having," and lacks proper structure for a participial phrase.

B) Being warned, he proceeded with caution.
C) To be warned, he proceeded with caution.

Option Analysis:
Option A:
Contains a past participle but not in a perfect form.
Option B:
Uses a present participle, which does not indicate a completed action before the main verb.

7.
Hearing the noise the boy woke up. [Here 'hearing' is ..... ]
A) Present Participle.
B) Past Participle.
C) Infinitive.
D) None of the above.
Show Answer
Explanations:
The phrase "Hearing the noise" functions as an adjective modifying "the boy," describing a condition under which he woke up. In English grammar, this is known as a present participle functioning as an adjective. The -ing form of the verb (hearing) acts as an adjective here.
Option Analysis:
Option A:
Correct. "Hearing" is a present participle acting as an adjective.
Option B:
Incorrect. Past participles are typically used with auxiliary verbs and do not directly modify nouns in this way.
Option C:
Incorrect. Infinitives begin with "to" (e.g., to hear) and do not function as adjectives here.
Option D:
Incorrect. There is a correct answer among the options provided.
8.
They ..... about the meeting because they arrived exactly on time.
A) Can't have forgotten.
B) Must have forgotten.
C) Could forget.
D) None of the above.
Show Answer
Explanations:
The sentence indicates that the individuals arrived on time, which suggests they did not forget about the meeting. The perfect infinitive "can't have forgotten" is used to express a strong inference based on evidence (arriving on time). This construction implies a high level of certainty that the action (forgetting) did not occur in the past.
Option Analysis:
Option A:
Correct. Indicates strong inference from evidence.
Option B:
Incorrect. "Must have forgotten" suggests certainty about an action, which contradicts arriving on time.
Option C:
Incorrect. "Could forget" is a possibility and does not align with the given context of being on time for the meeting.
Option D:
Incorrect. There is a correct answer among the options provided.
9.
By the time they graduate, they hope to ..... at top-tier companies.
A) Have passed.
B) Have interned.
C) Finished.
D) Aim.
Show Answer
Explanations:
The perfect infinitive is formed with "have" + past participle, indicating an action completed before another in the past. In this context, "have interned" fits perfectly as it shows a completed action (interning) that they hope to have done by the time of their graduation.
Option Analysis:
Option A:
Have passed - Incorrect; 'passed' is not relevant here.
Option B:
Have interned - Correct; it uses perfect infinitive correctly, indicating a completed action before the time of graduation.
Option C:
Finished - Incorrect; while close, "have finished" would be more appropriate in this context to match the perfect infinitive structure.
Option D:
Aim - Incorrect; 'aim' is a base form verb and does not fit the perfect infinitive construction required here.
10.
What is the perfect infinitive form of 'to go'?
A) To be gone.
B) To go.
C) To have gone.
D) To have been gone.
Show Answer
Explanations:
The perfect infinitive form of 'to go' is
To have gone.
This construction indicates an action that was completed before another past action and is formed by combining the auxiliary verb "have" with the past participle "gone."
Option Analysis:
Option A:
Incorrect. "To be gone" is a passive form indicating a state of being absent.
Option B:
Incorrect. This is the simple infinitive, not the perfect infinitive.
Option C:
Correct. "To have gone" uses the auxiliary verb "have" with the past participle "gone," forming the perfect infinitive.
Option D:
Incorrect. This is a form used to express a completed action in the past, not an infinitive form.
11.
My wife made me go shopping with her last Saturday, but I ..... gone fishing instead.
A) Could have.
B) Must have.
C) Might have.
D) Would rather have.
Show Answer
Explanations:
"Would rather have" is used to express a preference for one action over another in the past, which fits the context of the sentence where the speaker preferred fishing over going shopping with his wife. This option correctly conveys the sense of regret or preference for an alternative action.
Option Analysis:
Option A:
Could have - implies a possibility but not necessarily a preference, which is not what the sentence expresses.
Option B:
Must have - suggests necessity rather than preference, and does not fit the context of the speaker's choice.
Option C:
Might have - indicates uncertainty or possibility without expressing a clear preference, which is not appropriate here.
Option D:
Would rather have - correctly expresses the speaker’s preference for fishing over going shopping with his wife in the past.
12.
..... the car, he went to a restaurant.
A) Parking.
B) Having park.
C) Parked.
D) Having parked.
Show Answer
Explanations:
The sentence uses the perfect infinitive "Having parked" to indicate that the action of parking was completed before going to the restaurant. This structure is used to show a sequence of events where one event (parking) happened before another (going to the restaurant).
Option Analysis:
Option A:
"Parking" is in base form and does not indicate that the action was completed before going to the restaurant.
Option B:
"Having park" is grammatically incorrect; it should be "parked" for correct tense usage.
Option C:
"Parked" alone does not show the sequence of events as well as "Having parked" does.
Option D:
"Having parked" correctly uses the perfect infinitive to indicate that parking was completed before going to the restaurant, making it the correct choice.
13.
These flowers are dried out. You ..... them regularly.
A) Can't have watered.
B) Shouldn't have watered.
C) Mustn' have watered.
D) Needn't have watered.
Show Answer
Explanations:
The sentence "These flowers are dried out. You ... them regularly." implies a situation where the flowers should have been watered but were not, leading to their current state of being dried out. The perfect infinitive form "Shouldn't have watered" (Option B) is used here to express a past action that led to an undesirable result in the present.
Option Analysis:
Option A:
Can't have watered - This implies the flowers were never watered, which doesn't fit the context of the sentence.
Option B:
Shouldn't have watered - Correct. It expresses a past action that led to an undesirable result in the present.
Option C:
Mustn't have watered - This implies a rule or obligation, which is not indicated by the sentence context.
Option D:
Needn't have watered - This suggests the action was unnecessary, but the flowers being dried out indicates it was needed.
14.
Which sentence uses a perfect gerund?
A) To see the movie was my goal.
B) I will see the movie tomorrow.
C) Seeing the movie was fun.
D) Having seen the movie, I can discuss it now.
Show Answer
Explanations:
Option D uses a perfect gerund, "Having seen the movie," which indicates an action completed before another in the past and is used to introduce a clause that modifies the main verb "can discuss."
Option Analysis:
Option A:
Uses a bare infinitive "To see" as part of a sentence structure indicating purpose.
Option B:
Uses a simple future tense, not involving any gerund form.
Option C:
Uses a present participle "Seeing," which is not perfect and does not indicate an action completed before another in the past.
Option D:
Correct. Perfect gerund used to show that the movie was seen before discussing it.
15.

A) Impossibility.
B) Hope.
C) Past obligation was not carried out.
D) None of the above.
Show Answer
Explanations:
The sentence "You should have locked the door before leaving the house" expresses a past obligation that was not fulfilled, which aligns with Option C: Past obligation was not carried out. This is an example of the perfect infinitive construction in English, where "should have" (a modal verb) + past participle ("locked") indicates a recommendation or duty that was missed in the past.
Option Analysis:
Option A:
Impossibility - Incorrect. The sentence does not imply anything about impossibility.
Option B:
Hope - Incorrect. There is no expression of hope in this sentence.
Option C:

The glass might be broken.
A) True.
B) False.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "The glass might be broken" uses the perfect infinitive form "might have been," which is implied in the modal verb "might."

Since the question does not provide any context to deny this possibility, it can be considered true.
Option Analysis:
Option A:
True - The sentence uses a modal verb indicating a possible past event.
Option B:
False - Incorrect as there is no information provided that negates the possibility of the glass being broken.
Option C:
All the above - Not applicable since only one option (A) is correct based on the sentence structure and context.

None of the above - Incorrect as Option A is true.

Option A:
Might feel - Incorrect, as it refers to a possible future state.
Option B:
Must have felt - Correct, as it expresses certainty about a past action based on evidence or context.

This structure is appropriate for expressing an action that has been completed before another in the future. The use of "have earned" indicates a past action with present relevance, fitting well within the context of expecting to achieve a goal.
Option Analysis:

Completed - Incorrect; does not fit grammatically or semantically.
Option B:
Earned - Correct; uses perfect infinitive "to have earned" appropriately.

20.
In 'The witness appears ..... the crime happen, ' which form creates the most logical temporal relationship?
A) To be seeing.
B) To have seen.
C) Seeing.
D) To see.
Show Answer
Explanations:
The perfect infinitive "to have seen" (Option B) creates the most logical temporal relationship in the sentence because it indicates that the act of seeing occurred before the crime happened, establishing a clear sequence of events: the witness saw something or someone prior to the crime taking place.
Option Analysis:
Option A:
"To be seeing" is incorrect as it implies an ongoing action at the time of the crime, not before.
Option B:
"To have seen" correctly indicates a past action that occurred prior to another event (the crime).
Option C:
"Seeing" is in present participle form and does not indicate completion or sequence of events.
Option D:
"To see" implies an action that has not yet happened, which does not fit the temporal relationship required by the sentence.
21.

B) She regrets leave the party early.
C) She regrets having left the party early.

Show Answer
Explanations:

Option Analysis:
Option A:
Incorrect as it suggests Martha should have done the action, which contradicts the intended meaning.

D) She said having completed the assignment last week.
Show Answer

This sentence correctly uses a perfect infinitive "to have completed" in reported speech about a past event, where the action of completing the assignment has been fully accomplished before another past time (last week).
Option Analysis:
Option A:
Incorrect. The phrase "is said to complete" is not a perfect infinitive and does not accurately represent reported speech about a completed past event.

Frequently Asked Questions
What is a perfect infinitive?
A perfect infinitive is formed by using "to have" followed by the past participle of a verb. For example, in "to have eaten," "have eaten" is the past participle used with "to" to form this construction.
How does a perfect infinitive differ from a simple infinitive?
A simple infinitive is just the base form of a verb preceded by "to," such as "to walk." A perfect infinitive, on the other hand, uses the past participle with "have" to indicate an action completed before another action or time. For example, "to have walked" indicates an action that happened in the past and is relevant to a present context.
Can perfect infinitives be used with adjectives?
Yes, perfect infinitives can function as adjectives. For example, in the sentence "The book to have read is on the shelf," "to have read" modifies "book" and indicates that the book has already been read.
What are some common uses of perfect infinitives?
Perfect infinitives are often used to express past actions with relevance to the present, such as in sentences like "I am happy to have met you," where the action of meeting is relevant to the current state of happiness.
How do perfect infinitives relate to other verb forms?
Perfect infinitives are closely related to perfect participles, which are used in the same way. For example, "having eaten" and "to have eaten" both indicate a completed action that is relevant to another context or time.
