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don’t或doesn’t ；
① 句中动词为原形的，加don’t .如： I like apples. ?I don’t like apples.②句中动词为三单式的，加doesn’t，并将三单式的动词还原成原形。
如：He likes apples.? He doesn’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.
2.I play computer games every night.
3.I have a TV.
三.陈述句变一般疑问句应注意的事项
陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点：
1.如果陈述句中有第一人称，则变问句时最好要变为第二人称。 例：I usually have lunch at school.
→Do you usually have lunch at school?
My father is playing soccer.
→Is your father playing soccer?
2.如果陈述句中有some, 则变问句时往往要变成any 。
例： There is →Is there3．如果句中含有实义动词have且表示“有”时,除借do外，也可将其直接提到句首。
例：I have some friends in America.
→Have you any friends in America?/Do you have any friends in America? 综合练习：
1. His father is an English teacher.
2. These cats are crying.
3. They can swim.
4. I like to read English.
