Please, keep quiet , I am trying to study.

 

A:Lily, can you go to the mall this week?
B: Sure , I love to .

Sorry , I can’t go to your party , because I have to babysit my sister.

The whole world has changed in five years.

He will not be free till next weekend.

He can’t come to your party, because he has to study for the coming difficult test.

Think about that the next time you're waiting in line on a Friday afternoon.

 

He is going to have a piano lesson this weekend.

And then, frankly, I would go to the doctor and get a basic old blood test.

He will have a chance to see his idol the day after tomorrow.
