Gerund And Infinitive

Why A is correct:
"Love" is the base form of the verb needed here. The sentence structure "I ___ playing" requires a simple present tense verb without "to," so "love" fits perfectly: "I love playing the piano."

Why the others are wrong:
- B (to love): You don't use the infinitive "to" after "I" in this position; that would be grammatically incorrect.
- C (loves): This is third person singular (he/she/it loves), but the subject is "I," which needs the base form.
- D (loved): This is past tense, but nothing in the sentence indicates the action happened in the past.

Correct answer: A. wants

• This sentence needs a present-tense verb after the subject "He." The structure is "He [verb] to eat..." and "wants" is the correct conjugated form.
• B (to want) - The infinitive "to" is already in "to eat," so we don't need another one here.
• C (wanted) - This is past tense, but nothing in the sentence indicates a past action.
• D (wanting) - This is a gerund/participle form, but we need a main verb in the simple present tense to match the meaning "every day" (habitual action).

# Explanation

A. enjoys ✓ Correct
The sentence needs a present-tense verb after "She." "Enjoys" is the right form—it's the third-person singular present tense that matches the subject "she."

B. enjoying ✗
This is a gerund (verb + -ing), which can't be the main verb here. You'd need an auxiliary verb first, like "is enjoying."

C. to enjoy ✗
This is an infinitive. It's used after certain verbs (like "want to enjoy") but doesn't work as the main verb on its own.

D. enjoyed ✗
This is past tense. Nothing in the sentence indicates we're talking about something that already happened, so present tense is correct.

A. like ✓

After "they" (a plural subject), use the base verb form "like" without any additions. This is the correct present tense form.

Why the others are wrong:
- B. liking — This is a gerund/present participle; you'd need "are liking" (with a helping verb) for continuous tense
- C. to like — This infinitive form doesn't work here; you'd only use it after certain verbs like "want to like"
- D. liked — This is past tense, but the sentence describes a current habit ("in their free time" = present)

A. want ✓

After "do you," we use the base form of the verb. "Do you want to go shopping?" is the correct structure for forming a question in present tense.

Why the others are wrong:
- B. to want – The infinitive form (to + verb) doesn't work here; we need just the base verb after "do"
- C. wanted – This is past tense, but the question asks about now, not the past
- D. wanting – The -ing form doesn't fit with "do you"; that would need "are you"

A. would like ✓
This is correct because "would like" is the proper verb form to express a future wish or desire. It follows the pattern: subject + "would like" + infinitive verb.

B. to would like ✗
This has incorrect word order. You don't put "to" before "would like"—"to" comes after "like" if you're using an infinitive (e.g., "I would like *to* visit").

C. likes ✗
This is present tense and doesn't match the meaning. "Likes" describes something you enjoy now, not a future goal or polite desire.

D. liked ✗
This is past tense. "Liked" refers to something you enjoyed in the past, not a future aspiration.

Why A is correct:
"Likes" is the base form verb needed after the subject "he." It matches the present tense and follows the simple pattern: subject + verb + infinitive (to watch).

Why the others are wrong:
- B (to like): You don't use "to like" after the subject—that's the infinitive form, which comes after certain verbs like "want" or "try," not as the main verb here.
- C (liked): Past tense doesn't fit—there's no indication this is about the past.
- D (liking): The gerund (-ing form) doesn't work as the main verb in a simple present sentence like this.

Correct Answer: A. want

After "I," you need the base form of the verb (infinitive without "to"). "Want" is the correct simple present form that agrees with the subject "I."

Why the others are wrong:
- B. to want — Using "to" creates an infinitive phrase, which doesn't work after "I" in this sentence structure
- C. wanted — Past tense doesn't fit the context; there's no indication this is about the past
- D. wanting — The "-ing" form (gerund) doesn't work here; you need a conjugated verb to match the subject

A. likes ✓
This is correct because "likes" is the simple present tense verb that matches the subject "she" and fits the sentence structure "She [verb] to [infinitive]."

B. to like ✗
This is an infinitive form, but you need a conjugated verb after the subject "she," not another infinitive.

C. liked ✗
This is past tense, but there's no time marker suggesting the past (like "yesterday" or "last week"), so present tense is appropriate here.

D. liking ✗
This is a gerund/present participle, but it doesn't fit the structure—you'd need "She likes listening..." or just "She [verb]" without the infinitive "to music."

A. enjoys ✓
After "He," you need a conjugated verb in the correct tense. "Enjoys" is the simple present tense, which matches the ongoing habit described ("on weekends").

B. enjoying ✗
This is a gerund (verb form ending in -ing). It can't follow "He" directly without a helping verb like "is" (He is enjoying).

C. to enjoy ✗
The infinitive form doesn't work here. You'd need it after certain verbs like "wants" (He wants to enjoy).

D. enjoyed ✗
This is past tense, but the sentence describes a regular, present-day habit, not something that already happened.

Why A is correct:
After "enjoys," you need a gerund (verb + -ing). "Enjoys watching" is the correct pattern.

Why the others are wrong:
- B (to watch): This is an infinitive. "Enjoys" doesn't take infinitives—it takes gerunds.
- C (watch): Base verbs don't work here; you need the -ing form.
- D (watches): This is present tense, but you need a gerund after "enjoys."

A. to buy ✓

After the verb "promise," you need an infinitive (to + verb). "They promised to buy me a gift" is correct.

• B. buying — This is a gerund (noun form). "Promise buying" doesn't work in English.
• C. buy — This is a bare infinitive without "to." After "promise," you must include "to."
• D. buys — This is present tense. "Promise buys" doesn't make grammatical sense here.

Correct answer: A. waking up

After the verb "hates," you need a gerund (verb + -ing), not other verb forms. "Waking up" is a gerund that works as a noun object of the verb "hates."

Why the others are wrong:
- B. woke up — This is past tense; you can't use a simple past tense form after "hates"
- C. wake up — This is the base form; it doesn't function as a noun that can follow "hates"
- D. wakes up — This is present tense with a subject; it's a complete clause, not a noun object

Correct answer: A. eating

After "can't stand," you need a gerund (verb + -ing form), not a base verb or past tense. "Can't stand" is a phrasal verb that requires a gerund object, so "eating seafood" works perfectly.

Why the others are wrong:
- B (ate): Past tense doesn't fit here; you'd need "I can't stand that I ate seafood" with extra words.
- C (eat): Base verb doesn't work after "can't stand"—you need the gerund form.
- D (eats): Present tense with -s is for third-person subjects ("he/she eats"), not after "can't stand."

A. to become ✓

After "wants," you need the infinitive form (to + verb). "She wants to become fluent" is correct.

• B. become — Missing "to"; grammatically incorrect after "wants"
• C. becomes — This is present tense, but we need the infinitive here
• D. becoming — This is a gerund/participle form; "wants becoming" doesn't work in English

A. playing ✓

After the verb "loves," you need a gerund (verb + -ing). Gerunds act as nouns and follow certain verbs like "love," "enjoy," and "hate."

• B. played — Wrong tense; "played" is past tense, but you need the -ing form after "loves."
• C. play — Wrong form; bare infinitive doesn't work after "loves" (you'd need "to play" if using an infinitive).
• D. plays — Wrong; this is present tense, but "loves" already shows the main action. You can't have two present verbs in this structure.

Why A is correct:
After the verb "enjoys," you need a gerund (the -ing form of a verb). "Enjoys taking" is the correct phrase.

Why the others are wrong:
- B (took): Past tense doesn't fit here; you don't "enjoy took."
- C (take): Base form doesn't work after "enjoys"; you'd say "enjoys to take" (awkward) or "enjoys taking" (correct).
- D (takes): Present tense form doesn't fit; you don't "enjoy takes."

A. to lose ✓

After "want," you must use the infinitive form (to + base verb). "She wants to lose her book" follows the pattern "want + infinitive."

Why others are wrong:
- B (lose) – Missing "to"; bare verbs don't work after "want"
- C (loses) – This is third-person present tense, not an infinitive
- D (losed) – Not a real word; "lose" doesn't form past tense this way

A. to go ✓

After "would like," you need the infinitive form of the verb (to + verb). "Would like to go" is the correct structure.

• B. go — Missing "to"; the infinitive requires "to" after "would like"
• C. goes — This is present tense, but "would like" requires an infinitive, not a conjugated verb
• D. went — This is past tense and doesn't fit the structure of "would like"; it also lacks "to"

A. sunbathing ✓

After "like," you need a gerund (verb + -ing) to show an activity or hobby. "Sunbathing" is the gerund form and correctly completes the sentence.

Why the others don't work:
- B. sunbathed — This is past tense, but the sentence is about what they like to do in general, not something they already did.
- C. sunbathe — This is the base verb form, which doesn't work after "like" (we don't say "like to sunbathe" without "to").
- D. sunbathes — This is third-person singular present tense, used for he/she/it, but we need a gerund here, not a conjugated verb.
