改写句子

做题方法

一、先看有没有
b
e
的各种
形式、
have
的各种形式或情
态动词 ,
没有就说明这个句
子的助动词是
do


因为在
句子里助动词

置是:
be

谓语动
词的前面,变
否定
例子

be

have
的各种形式或情态动词在谓语动词的前面。

He

He
is not
going to see his uncle this afternoon.
Is he going to see his uncle this afternoon.
I have finished my homework.
I
have not
finished my homework.
Have you finished your homework.
Da Shan
can
speak Chinese well.
句:
只要在它们后面直接加
not,
而助动词
do
常隐藏在
谓语 动词里的。
这时要先把
助动词找出来,
提前,
再加
Da Shan
can not
speak Chinese well.
Can Da Shan speak Chinese well.
助动词
do
常隐藏在谓语动词 里的。
这时要先把助动词找出来,
提前,再加

(
当谓语动词是原形时,助动词就是
