小学英语肯定句变否定句特殊疑问句详解
小学英语肯定变否定 及特殊疑问句解析
一 肯定句变否定句 1. 谓语动词是系动词 be 、情态动词或助动词时,直接在这些词的后面加上否定词(当谓语动词为be动词时,变否定句看到some变any)。 如:
I am a teacher. → I am not a teacher.
Li Lei can swim. → Li Lei can not ( can't ) swim.
There are some books on the table.---- There are not any books on the table.
2. 谓语动词是一般动词时,要根据时态选用 do 的相应形式,即 do / does / did not ,并把该谓语动词恢复原形。如:
I get up at six o'clock every day. → I don't get up at six o'clock every day. Mr Wang works in a factory. → Mr Wang doesn't work in a factory.
Xia Lin visited our friends last night. → Xia Lin didn't visit our friends last night.
二 肯定句变一般疑问句
1.将肯定句变为一般疑问句时,如句中有be 动词(am is are …)时,可直接将它们提至主语前(如主语为第一人称,应将其改为第二人称。看到some变any。)如:We're watching TV. → Are you watching TV﹖
2.肯定句中有情态动词(can may must …)时,也可直接将它们提至主语前,即可成为一般疑问句。如:
The children may come with us. → May the children come with us﹖
3. 谓语动词是一般动词时,根据do相应的时态在句首加do,does,did.动词用原形。 She wants to go to the park → Does she want to go to the park﹖
