一、 肯定句变否定句
1> 看肯定句中有没有be动词（am、is、 are、 was、 were）或情态动词（can），如果有，直接在其后加not，其余照抄就可以。
1、在be动词后加not。如：is not ， are not ， am not， was not， were not；
2、在can，等后加not。如：can not(缩写 can’t)
2> 如果句中没有be动词或情态动词，变否定要找助动词do的相应形式（do、does、did）帮忙，且原句的谓语动词要变回原形。
否定句中and，some与any的用法 1. 否定句中and要变为or 2. 否定句中some要变为any |
二、一般疑问句
1、定义: 以be动词/助动词/情态动词开头的句子叫一般疑问句。
2、特点：用yes/no回答。
例：Is your father a teacher? 翻译：你的父亲是一名老师吗？ 结构：Be动词 主语 其他
Does Tom like apples? 翻译：汤姆喜欢苹果吗？ 结构：助动词 主语 动词原形 其他
Can Jenny speak English? 翻译：珍妮会说英语吗？ 结构：情态动词 主语 动词原形 其他
3、陈述句变成一般疑问句的方法：
1）看陈述句中有没有be动词（am/is/are/was/were）或情态动词（can），如果有，将其提到句首，其余照抄，句末打上“？”即可。
例：It was rainy yesterday.
变一般疑问句→
Tom's father can play the piano.
变一般疑问句→
2）如果句中没有be动词或情态动词，句首加do的相应形式（do、does、did），其余照抄，且原句的谓语动词要变回原形。
例：They go to school by bike. →
Bill gets up at 6:30 every day. →
The students saw a film yesterday. →
注： 1.如果陈述句中有第一人称，则变问句时要变为第二人称。 I usually have lunch at school. 2.如果陈述句中有some, 则变问句时往往要变成 any 。 There is some water on the playground. |
4、一般疑问句的回答。
例：---Does she clean her room every day? ---Yes, ________.
---Is Anna′s father a doctor? ---No，________.
---Can she dance? ---Yes,________.
如果问句主语是 this that,回答时用____代替；若问句主语是these, those,回答时用 _____代替。
--Is this your bag? --Yes, ________ ./ No,________ .
--Are those your books? --Yes, ________. / No, ________.

三、特殊疑问句

2、结构：特殊疑问句=特殊疑问词 一般疑问句

如：1)Who is singing in the room﹖ 2)Where is he?
２>．如疑问词作其他成分，即对其他成分提问，其语序是：疑问词 助/be/情 主语 其他
