My plans for summer break:

This summer break is very important to me, because it may be my last summer break in China. So,  I must do something significant that I can't do in America, like getting my driver's lincense and spending time with my family. Quite a few of my classmates have their driver's linceses already. That makes me feel bad.   I must (or, have to) get mine ASAP. Besides, my cousin has just gone through a really difficult time  in GAO KAO.   We both want to  spend some time together while we are still young, and I know this summer may be the last chance we get . Getting my  lincense and playing with my cousin- that is my summer break plan.

(I had to guess what you meant in a few of these sentences.  I hope I guessed correctly!)
