should be sure to do
1个回答

should和be能一起用.

后一种表达法更为确切.

Be sure意思是已经sure了:

I am sure you will do well on the exam if you study hard.

Are you sure he's the guy you were talking about?

Make sure强调过程,从不sure到sure或从sure到更sure的过程:

Make sure you will bring your umbrellas tomorrow in case it rains.

I will make sure that everyone gets a book.
