句型转换的方法
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；
2、 在can，should， will等后加not。如：cannot， should not， will not；
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。
把下面的句子变成否定句。

5.The cat runs fast.

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，（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。
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

3、 上述都没有的，在句首请助动词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。
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? 把下列句子改为一般疑问句。

三、 肯定句改特殊疑问句的方法——四步法
1、在一般疑问句的基础上，句首添加一个疑问词即可，可根据划线部分确定是什么疑问词。
2、接着找be动词或can，shall， will等放在疑问词后面，若没有则请助动词do/does/did帮忙，写在疑问词后面，how many除外，必须先写物品，再写be动词等。
3、划线部分去掉后剩下的内容照抄，（some 改成any，my改成your等）
4、句点改成问号。
