英语5B句型转换练习（二）

否定句

一、在be动词（am
is
are）和情态动词(can, may, must...)后面加not，其它照写。some变成any.

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

否定句:
They are not in the park.

He can  not play the guitar.

或：
They aren’t in the park.

He can’t play the guitar.

am not 不能缩写
is not=isn’t
are not=aren’t
can not=can’t

把下列句子变成否定句

1.       I
am
listening
to
music.

_______________________________________

2.       Mike
is
a

_______________________________________

3.       Sarah

4.       They

the
vase.

6.This

my
sister.
_________________________________________
7.We

the
floor.

二、借助动词don’t/doesn’t,第三人称单数用doesn’t,其余人称用don’t，放到人称后面，动词前面其他照写。特别记住：前面用doesn’t, 后面的动词一定还原成原形。Some变成any.

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

否定句：I don’t
like the ducks.
He doesn’tlike the dogs?

把下列句子改为否定句。
4.
We need some masks.
