Answer 2

Answer in detail. Choose the right answer. In the affirmative and negative form, between the modal verb must and the main (meaningful) verb, the particle to _________________. never used always used sometimes used

The correct answer is never used. The modal verb must is followed by the main verb in the infinitive form without to. For example:

- You must study hard for the exam. (Утвердительная форма) - You must not smoke in the hospital. (Отрицательная форма)

The particle to is used with the modal verb have to, which can also express necessity or obligation. For example:

- I have to finish this project by tomorrow. (Утвердительная форма) - I don't have to work on weekends. (Отрицательная форма)

The difference between must and have to is that must expresses a personal or internal obligation, while have to expresses an external or objective obligation. For example:

- I must exercise more. (This is my personal decision or feeling) - I have to pay the rent. (This is a rule or a fact that I cannot change)
