To complete this sentence, we need to use the base form of the verb "do" after the word "make" because "make" is a causative verb that is followed by another verb in its base form without the "to" particle. So, the correct form is "do" instead of "doing" or "to do."
2. The kitchen windows need cleaning.
In this sentence, we need to use the gerund form of the verb "clean" after the word "need." When we talk about the necessity to do something, we use the structure "need + verb" with the verb in its gerund form. So, the correct form is "cleaning" instead of "to clean" or "cleans."
3. They have begun making predictions for the party.
To form the present perfect tense in this sentence, we need to use the auxiliary verb "have" followed by the past participle of the verb "begin." After that, we need to use the base form of the verb "make" because it is used as an infinitive after "have begun." So, the correct form is "making" instead of "to make" or "makes."
4. He advised her to speak to her boss.
In this sentence, we need to use the base form of the verb "speak" after the word "advised" because "advise" is followed by an infinitive verb with "to." So, the correct form is "to speak" instead of "speaking" or "speaks."
5. I dislike going to the theatre alone.
In this sentence, we need to use the gerund form of the verb "go" after the word "dislike." When we express our feelings or opinions about an activity, we use the structure "dislike + verb" with the verb in its gerund form. So, the correct form is "going" instead of "to go" or "goes."
6. Mr Roberts was seen leaving his house at 12:15 last night.
To form the past continuous tense in this sentence, we need to use the past continuous form of the verb "see" (was/were + present participle) followed by the present participle of the verb "leave" (leaving). So, the correct form is "leaving" instead of "to leave" or "leaves."
7. My sister can't stand watching horror films.
In this sentence, we need to use the gerund form of the verb "watch" after the word "can't stand." When we talk about someone's strong dislike or intolerance for an activity, we use the structure "can't stand + verb" with the verb in its gerund form. So, the correct form is "watching" instead of "to watch" or "watches."
8. Can you imagine spending your holidays on the moon?
To form a question in this sentence, we need to use the auxiliary verb "can" followed by the base form of the verb "imagine" and the gerund form of the verb "spend." So, the correct form is "spending" instead of "to spend" or "spends."
9. There's no point in calling again. There's no one at home.
In this sentence, we use the gerund form of the verb "call" after the phrase "no point in." When we want to say that an action is pointless or has no purpose, we use "no point in + verb" with the verb in its gerund form. So, the correct form is "calling" instead of "to call" or "calls."
10. I don't allow people to smoke in my house.
In this sentence, we need to use the base form of the verb "smoke" after the word "allow" because "allow" is followed by an infinitive verb with "to." So, the correct form is "to smoke" instead of "smoking" or "smokes."
11. It was silly of you to forget to lock the door.
In this sentence, we need to use the base form of the verb "forget" after the word "to" because "to" is used to indicate purpose or result. So, the correct form is "to forget" instead of "forgetting" or "forgets."
12. He risks losing his wallet when he leaves it on his desk.
In this sentence, we need to use the gerund form of the verb "lose" after the word "risks." When we talk about the possibility of a negative consequence or potential danger, we use the structure "risk + verb" with the verb in its gerund form. So, the correct form is "losing" instead of "to lose" or "loses."
