英语一般疑问句引导词怎么使用

更新时间2019-01-14 00:34:21

在一般疑问句中什么时候用do（其他时态）be（am，is，are）什么时候用have（其他时态！谢谢......

1. 一般疑问句中，如果原来的句子中只有实义动词，那么在改成一般疑问句的时候就要用助动词do,does或did，而原来的实义动词要用原形。如：

He likes playing basketball. 改成：Does he like playing baketball?

She went to the park yesterday. 改成： Did she go to the park yesterday?

2. 在含有am, is, are和have, has, had的句子中，直接把这些词放在句首即可，如：

I am mad. 改成： Am I mad? 或者：Are you mad?

She is from Canada. 改成： Is she from Canada?

They are interested in English. 改成： Are they interested in English?

They have arrived in Shanghai. 改成：Have they arrived in Shanghai?
