getting married costs a lot,getting devorced costs much more
2个回答

1.wonder if she has been invited.

has been 是什么时态,为什么不用be而用been呢?

答:虚拟语气

2.didn't tell me the truth,既然did都用过去式,tell为什么不用过去式?

答:这是最基本语法呀!一个句中出现两个动词只需将助动词按时态写,就像这句:他不喜欢我,he dosen't like me .而不是he dosen't likes me .一样.

3.getting married costs a lot,getting devorced里面的married 和devorced 所指的并不是动词.加上d其实是动词名用的一种方法.

4.What i appreciated 和was his friendliness很明显在表达一种过去的事情.所有前后一致都用过去式
