Answer 1

B. Я не должен лечь поздно сегодня ночью или ты не сможешь проснуться рано на работу.
Must-должен, обязан. То есть употребляется в предложениях повелительного наклонения

Answer 2

The correct answer is E) had better not.

The sentence is expressing a warning or advice about staying up late tonight. The phrase "had better not" is used to suggest that it would be a good idea not to do something in order to avoid a negative consequence. In this case, the negative consequence is not being able to get up early for work.

Here's a breakdown of the different options:

A) should not: This option implies a general recommendation or suggestion, but it doesn't convey a strong sense of urgency or consequence. It's not as strong as the warning given in the sentence.

B) must not: This option implies a prohibition or requirement, but it doesn't convey the same sense of advice or warning. It suggests that it is necessary not to stay up late, but it doesn't emphasize the potential negative consequence.

C) need not: This option suggests that it is not necessary to stay up late, but it doesn't convey the urgency or warning about the potential negative consequence.

D) ought not to: This option is similar to "had better not" and could also be considered correct. It suggests that it would be advisable not to stay up late, similar to "had better not."

E) had better not: This option is the best fit for the sentence because it conveys a strong sense of advice and warning. It suggests that it would be in the person's best interest not to stay up late in order to avoid the negative consequence of not being able to get up early for work.

So, in conclusion, the correct answer is E) had better not.
