Task 1. Choose all sentences where it's necessary to use particle "to" with infinitives. Отметьте все предложения, в которых необходимо использовать частицу "to"с инфинитивом. I went to the library (study) last night. I’d like (dance). Don’t let your children (swim) in the river. Would you like (join) us?

Answer 1

To используем для:

• выражения цели
• выражения предпочтения с would like, would rather...
• выражения эмоции с happy, glad...

и кое-чего ещё.

I went to the library to study last night — цель.

I'd like to dance — предпочтение.

Would you like to join us? — предпочтение.

Answer 2

Here are the sentences where it's necessary to use the particle "to" with infinitives:

1. I’d like (to dance).
2. Don’t let your children (to swim) in the river.
3. Would you like (to join) us?

The sentence "I went to the library (study) last night." is not in need of the particle "to" before the infinitive "study."
