Step4：语法复习

一般疑问句

一、在be动词（am/is/are）和情态动词(can, may, must...)提前，其它照写。some变成any.

例如：陈述句: They are in the park. He can play the guitar..

一般疑问句: Are they not in the park？ Can he not play the guitar？

二、借助动词do/does,第三人称单数用does，其余人称用do，助动词提前，动词变为原形。特别记住：前面用does, 后面的动词一定还原成原形。Some变成any，I变成you.

例如：陈述句: I like the ducks. He likes the dogs.

否定句： Do you the ducks. Dose he like the dogs?
