英语中常见的省略动词有三种情况：省略be动词（如am、is、are等）、省略情态动词（如can、could、may等）和省略动词短语（主语和动词的组合）。这是英语口语中的常见现象，需要多加练习和熟练掌握。
1. 省略 be 动词
在英语中，be 动词包括 am、is、are、was、were 等，有时候在句子中可以省略，特别是在口语中更加常见。例如：
- Are you going to the party? → You going to the party?
- She is a teacher. → She a teacher.
2. 省略情态动词
情态动词包括 can、could、may、might、will、would、shall、should、must 等，也可以在句子中省略。例如：
- You should finish your homework before watching TV. → You finish your homework before watching TV.
- He may come to the meeting tomorrow. → He come to the meeting tomorrow.
3. 省略动词短语
动词短语包括主语和动词的组合，也可以在句子中省略。例如：
- I am watching TV while my sister is doing her homework. → I watching TV while my sister doing her homework.
- She is going to the store to buy some milk. → She going to the store to buy some milk.
