小学英语句型转换的方法
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。
它们因此也被称为功能词。
一、肯定句改否定句的方法
1、在be动词后加not。
如:is not ,are not ,am not,was not,were not;
2、在情态动词can,may, must, shall ,should,will, would , need 等后加not。
如:cannot,should not,will not;(won’t, can’t, shan’t)
3、上述都没有的,在动词前加助动词否定形式don’t/ doesn’t/ didn’t。
4、some 改成any, too 改成either, already 改成yet等。
二、肯定句改一般疑问句的方法(一提二改三问号/ 一加二改三问号)
1、把be动词放在句首,剩下的照抄,(some 改成any,my改成your等)句点改成问号。
2、把can,shall,will等放到句首,剩下的照抄,(some 改成any,my改成your等)句点改成问号。
3、上述都没有的,在句首加助动词Do/Does/Did帮忙,剩下的照抄,(some 改成any,my改成your 等)句点改成问号。
把下列句子变成一般疑问句
1. I am listening to music.
