I am not an Chinese expert, but I will give it a try.
1.Time will not wait.
2. This is the best movie I have seen.
3. By the end of last year, I had already learned 1000 new vocabularies.
4. We are reading the textbook when the teacher enters.
5. Not really sure what you are saying there. Do you mean It is very important for us to learn English?
I hope this helps.
