Answer 1

Ответ:

1 We went to the supermarket to buy some food.

2 The teacher thinks you are clever enough to understand it.

3 Young people can volunteer if they want.

4 Bruno won’t let me take his car.

5 I heard them quarrel yesterday.

6 She didn’t know why go there.​

Объяснение:

Bare infinitive - инфинитив без частицы to - употребляется в следующих случаях:

- после модальных глаголов must, may (might), can (could), needn't, shall, should, will, would (кроме ought, после которого следует инфинитив с частицей to)

- после глаголов to make (заставлять), to let (позволять), to have (заставлять), а также иногда после глагола to help (помогать)

- в сложном дополнении с инфинитивом после глаголов to see, to hear, to feel, to watch, to notice

- после вопросительного местоимения why, если за ним следует инфинитив

Full infinitive - инфинитив с частицей to - употребляется в следующих случаях:
- при выражении цели, определенной глаголом-инфинитивом (предложение 1)

- после таких глаголов, как advise, agree, appear, decide, expect, hope, manage, offer, promise, refuse, seem, want, afford, pretend и т. д.

- после таких прилагательных, как glad, nice, happy, sorry, willing, afraid, ashamed и др.

- когда инфинитиву предшествуют наречия too и enough (как в пункте 2)

Answer 2

Sure, in the sentences you've provided, the phrases in parentheses indicate the use of infinitives. Whether to use full infinitives or bare infinitives depends on the structure of the sentence and the verb tense or construction used. Here's how the sentences should be structured:

1. We went to the supermarket to buy some food. (Full infinitive: "to buy") 2. The teacher thinks you are clever enough to understand it. (Full infinitive: "to understand") 3. Young people can volunteer if they want. (Bare infinitive: "volunteer") 4. Bruno won’t let me take his car. (Bare infinitive: "take") 5. I heard them quarrel yesterday. (Bare infinitive: "quarrel") 6. She didn’t know why to go there. (Full infinitive: "to go")

In sentence construction, sometimes the infinitive is used in its full form ("to" + base verb), and sometimes it's used in its bare form (base verb without "to"). The choice depends on the structure of the sentence and the specific verb or construction used.
