All right. This is a holiday. I have many choices: I like the Romans; I watch American movies; I like to exercise to build up my physique. ...

Summer vacation is coming. I have a lot of things to do: reading novels, watching movies, exercising, and so on.

I am interested in navigators from other parts of China, such as Europe, Southeast Asia and Australia.

I am most interested in traveling around, even going abroad: Europe, Southeast Asia, Australia.

I don't doubt whether I have prepared for a year's course.

I must preview my lessons for the next school year.
