1.I like volley ball very much, and I practice (to play) it very day.
动词后接不定式.
不过这句话感觉很怪,我很少听人说practice to play/playing it.通常口语会直接说practice volley/it.
2.Could you play the piano more (quietly)? We are all watching TV.
这里需要一个副词修饰play.
3. Next week is May day. I am (going to visit) Beijing.
be going to do表将来.
这句话的时间也很怪.下周是五月的一天,和在/去北京有什么联系?说不清,想来应该比被动和现在进行好吧.
4.Would you like to come here and watch TV?
- yes, I am glad (to watch) a basketball game with you on TV.
be to do
不定式做主语的补语,系动词作谓语时叫标语,本质相同,都是补充说明主语的状态、功能等.
