英语所有句型转换的方法
基本助动词只有三个:be, do, have, 他们没有词汇意义,只有语法作用,如协助构成进行体,完成体,被动态,否定句,疑问句等。
一、 肯定句改否定句的方法——一步法
1、 在be动词后加not。如:is not , are not , am not, was not, were not,etc.
2、 在情态动词等后加not。如:cannot, could not
3、 上述都没有的,在动词前加助动词否定形式do not, does not.
4、 some 改成any。
二、 肯定句改一般疑问句的方法——三步法
1、 把be动词放在句首,剩下的照抄,句点改成问号。
2、 把情态动词等放到句首,剩下的照抄,句点改成问号。
例如:陈述句: They are in the park. He can play the guitar..
一般疑问句: Are they in the park? Can he play the guitar?
把下列句子变成一般疑问句
1. I am listening to music.

3、 上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,句点改成问号。过去式往往动词还原动词原形,不用过去时
例如:陈述句: I like the ducks. He likes the dogs.
一般疑问句:Do you like the ducks? Does he like the dogs?
