分不清何时使用系动词,何时使用DO
还有一个：助动词和它后面接的动词到底什么关系?
He is beautiful ,beautiful 是表语把?
系动词后面还能接什么?
在说话的时候什么时候直接用动词,什么时候要加助动词?什么时候用系动词?

1，系动词+形容词（做表语）You look nice. She is tall.
2，系动词+副词（表状态）The TV is always on at my home.里的on是副词，表示持续。
3，系动词+动名词（表示进行时）My favourite activity is reading.
4，系动词+名词性短语或者从句 That is why I like you. This is what I have ever said.
5，系动词+代词. You just look like me , behave like me, but the fact is I am myself.
应该还有，欢迎补充。本回答被网友采纳

在用一般现在时和一般过去时时,如果这句话里没有实义动词,就要用系动词,反之,就要用实义动词,用了实义动词后,如果该句表示强调、否定和疑问,就要再加助动词.
