一般疑问句、否定句的变法 学案（无答案）

陈述句变一般疑问句的方法 1. 当句子中含有be动词时，如am, is, are, was, were，将be动词提前。如：

He is sleeping. → Is he sleeping?

They are very busy. → Are they very busy ? She was very nice. → Was she very nice ?

They were at home yesterday. → Were they at home yesterday ? ※ I am a boy. → Are you a boy ? 注意：am变are， I 变you. 2. 当句子中含有have got 或has got 时，直接将Have 或has 提前。如：

They have got lots of books. → Have they got lots of books ? She has got a bike. → Has she got a bike ?

3. 当句子中含有can或will时，直接将can或will提前。如：

He can speak Chinese. → Can he speak Chinese ? She will go to Beijing. → Will she go to Beijing ?

4. 当句子中不含有以上词汇时，则根据主语、时态在句子前加助动词，如do，does，did，句子后面的动词要改为原形。

如：

They go to school by bike. → Do they go to school by bike ? She goes to school by bike. → Does she go to school by bike ?

He went to school by bike yesterday. → Did he go to school by bike yesterday ? 陈述句变否定句的方法 1. 当句子中含有be动词时，如am, is, are, was, were，在be动词后加not。如：

He is sleeping. → He is not sleeping. ( is not = isn’t )

They are very busy. → They are not very busy. ( are not = aren’t ) She was very nice. → She was not very nice. ( was not = wasn’t )

They were at home yesterday. → They were not at home yesterday. ( weren’t ) I am a boy. → I am not a boy.

2. 当句子中含有have got 或has got 时，在have或has后加not。如：

They have got lots of books. → They have not got lots of books. ( have not = haven’t ) She has got a bike. → She has not got a boke. ( has not = hasn’t ) 3. 当句子中含有can, will, must时，直接在can, will, must后加not。如：

He can speak Chinese. → He can not speak Chinese. ( can not = can’t ) She will go to Beijing. → She will not to to Beijing. ( will not = won’t ) She must go to school. → She must not go to school. ( must not = mustn’t )

4. 当句子中不含有以上词汇时，则根据主语、时态在主语后面加don’t , doesn’t, didn’t，句子后面的动词要改为原形。

如：

They go to school by bike. → They don’t go to school by bike. She goes to school by bike. → She doesn’t go to school by bike.

He went to school by bike yesterday. → He didn’t go to school by bike yesterday. ※ 陈述句中如果含有some时，不管是变一般疑问句还是否定句，都要变成any。
