英语否定句改肯定句

Question

如题所述

Answer 1

否定句变肯定句，1、一般情况下就是直接去掉not即可：He isn’t a good friend—He is a good friend.类似这样的词有：am is are can could may should might will shall have和has用在现在完成时中。
2、有时，需要去掉not和与其结合的助动词，还要改变动词的形式：He didn’t have a chance.—-He had a chance.
这种情况一般为一般过去时、一般现在时。
3含有any的要变为some，句末有either的要变为too。

Answer 2

中把否定句改成肯定句，如果距句中有情态动词be动词助动词的否定形式直接去掉not就可以，如果，行为动词做谓语的否定句，变肯定句直接去掉助动词don't ，doesn't和didn't，动词要根据句子语法变型
如
He isn't a student.
肯定句是 He is a student.

He doesn't work hard .
肯定句是，He works hard.

Answer 3

句中有以下词的,直接在这些词后面加NOT:

1.BE动词(am/is/are/was/were)2.情态动词(can/may/must/need/should....)3.的在其后加NOT，构成时态和语态的助动词(has/have/will/be...)
如:
I can swim.-------I can't swim.
She will come to see me next week.-----She (will not)(或won't) come to see me next week.

如果没有以上的词,则句子为一般现在时或一般过去时的肯定形式,变否定句时,先将动词变为原形,在动词前面助动词DO(DOES/DID),并在助动词之后加否定词NOT.助动词要根据时态和人称选用相应的.一般现在时用DO/DOES,其中DOES用于第三人称单数主语,DO用于除第三人称单数之外的其它主语.DID用于一般过去时,不论人称.

例如:
He goes to school on weekdays.-----He (doesn't go) to school on weekdays.
We went shopping last Monday.-------We (didn't go) shopping last Monday.
We like watching TV.------We (don't like) watching TV.

另外,除了NOT ,还有一些具有否定意义的词,以上是基本的,先记住这些.以上这些词变疑问也是要提前的

英语很简单又直白，例如否定句为This is not a book ，肯定句就是 This is a book.
