Company number:【WTUT-WT88Y-W8BBGB-BWYTT-19998】

一、陈述句改为一般疑问句:

1.当句子中含有be动词(am is are was were)或情态动词(can, could, may, should等)时,把be动词或情态动词提到句首。

如:①He is a he a docter ②They were in the house they in……

另外,为符合实际习惯

I am/We are..…------Are you… I was/We were…-----Were you….

I /We can…-----Can you…..

2.当句中含有实义动词时,也就是句子不含上面所提到那些be 动词或情态动词时,必须在句首加DO/Does/Did,具体情况分以下三方面:

㈠当句子中含有动词原型时,在句子前加Do, 其中,I + 动词。。。------Do you…

如:①I like you like music ②They work they work here

㈡当句子中含有的动词加S或es时,即句子是一般现在时,且主语为第三人称单数时,在句子前加Does.如: ①He likes he like music

②Tom comes from Tom come from China

( 注意 在此情况下,应把疑问句中的动词变原型。)

㈢当句子中的动词为过去式,在句子前加Did 再把动词变原型。如:

I went to the park you go to the….

He played football this he play……

二、陈述句改为否定句:

1.当句子中含有be动词(am is are was were)或情态动词(can, could , should等),在be动词或情态动词后加not.如:

①He is a docter. ----He is not a docter.

②They were in the house were not in……

③Tom can can not swim.

2.当句中含有实义动词时,也就是句子不含上面所提到的be动词或情态动词时,必须在原句动词前加don’t,或doesn ’t或didn’t:

㈠当句子中含有动词 原型时,在动词前加don’t:

如:I like music,-----I don’t like music. They go to school by don’t go to……

㈡当句子中含有的动词加s或es时,即句子是一般现在时,且主语为第三人称单数时,在句子中的动词前加doesn ‘t,再把动词变原型:

如:He likes doesn’t like music.
