专题: 把肯定句改成否定句
把肯定句改成否定句分以下情况:
1、句中有be动词的,在be动词后加not;
2、句中有情态动词的(can ,should,must ,would),在情态动词后面加not;
3、句中没有be动词和情态动词的,在动词前加d on’t或doesn’t ;
①句中动词为原形的,加d on’t.如: I like apples. →I do n’t like apples.
②句中动词为三单式的,加does n’t,并将三单式的动词还原成原形。
如:He likes apples.→ He does n’t like apples.
③时态为过去时的,要加didn’t 而且动词过去式要改为原形,
例:I went to school yesterday .→I didn’t go to school yeaterday .
4.肯定句中的some在否定句中应改为any
如:There are some students in the classroom.→ There are not any students in the classroom.

一般疑问句
一般疑问句
在英语的学习中,一般疑问句的转换及回答是经常碰到的问题,现在我们就来探讨一下有关一般疑问句的问题。
一、什么是一般疑问句
用Yes或No作答的疑问句叫一般疑问句。一般疑问句还有下列特点:1、以be动词、助动词或情态动词开头;例:Is your father a teacher? Does she like animals? Can Jenny speak Chinese?2、往往读升调;3、译成汉语,都可以带上“吗”,例如上面三句可分别译为:你父亲是老师吗?她喜欢动物吗?Jenny会说英语吗?
二、例何将陈述句变成一般疑问句?
要将陈述句变成一般疑问句,可以遵循下列步骤:
1.看句中有没有be动词(am、is、are、was、were)、和情态动词(can、must、will、may等),如果有,将其提到句首,句末打上问号即可。
例:She is a girl.
→Is she a girl?
Tom's father can play the piano.
→Can Tom's father play the piano?
练习:
1.This is a boy
2.It is a cat .
3.This is your sister.
4.Those are my books.
5.These are apples.
2.如果句中没有be动词、助动词或情态动词,则根据谓语动词的形式借助do
的相应形式放在句首。具体方法是:如果谓语动词是原形或者主语是第一人称、第二人称、第三人称复数则借do;如果谓语动词是一般现在时第三人称单数形式,则借does;需要注意的是,借does后,原句的谓语动词要变回原形。
例:They go to school by bike.
→Do they go to school by bike?
Bill gets up at 6:30 every day.
→Does bill get up at 6:30 every day?
练习:
1.I love my parents.
