—They went to the summer camp.

A. Where they did go on vacation B. What did they go on vacation C. What they did go on vacation 答案:D

思路分析:浏览题干可知问句是特殊疑问句,由“特殊疑问词+一般疑问句”构成,故排除 A,C 两项;据答语“他们去参加夏令营了”知问句询问“他们去哪儿度假了?”,排除 B 项,what 和 go 不搭配。

巧学一般过去时:

动词一般过去时,表示过去发生的事; be 用 was 或用 were,have 和 has 变 had; 谓语动词过去式,过去时间作标志;

一般动词加-ed,如是特殊得硬记。否定句很简单,主语之后 didn’t 添; 疑问句也不难,did 放在主语前; 谓语之前有 did,谓语动词需还原;

动词若是 was 和 were,否定就把 not 添。

D. Where did they go on vacation

二、难点聚焦

句式转换规则: 1.肯定句变为否定句时:

A.当句中含有情态动词 could,would,should 等时,可直接在其后加 not 构成否定句。

【例句】

I could get you a concert ticket. → I could not / couldn’t get you a concert ticket.

我不能给你弄到音乐会入场券。

B.当句中含有系动词 was,were 时,可直接在其后加 not 构成否定句。 【例句】

I was on the Internet when you called me. → I was not / wasn’t on the Internet when you called me.

当你给我打电话时,我没在上网。

C.当句中谓语是除情态动词、系动词 was, were 以外的动词时,在该动词之前加 did not / didn’t,动词还原,构成否定句。

【例句】

The famous singer sang some Chinese songs. → The famous singer did not / didn’t sing any Chinese songs. 那位著名的歌唱家没有唱中国歌曲。

2.陈述句变为一般疑问句时

A.移动词语的位置。将 was,were, could,would,should 等移到句首。 【例句】

He could pack his things himself. → Could he pack his things himself ? 他自己能整理东西吗?

B.添加助动词 did,谓语是除情态动词、系动词 was, were 以外的动词时,在主语之前加 did,动词还原。

【例句】

Mr. Li looked very old. → Did Mr. Li look very old? 李老师看起来很老吗?

3.陈述句变为特殊疑问句时

A.确定疑问词:人 who / whom,物 what,地点 where,时间 when / what time, 原因 why,频率 how often,长度 how long,距离 how far 等。

【例句】

They gave a speech last night. → When did they give a speech? 他们什么时候做的演讲?

B.辨认结构形式:疑问词+情态动词/助动词 did/ was / were +主语+...? 【例句】

The accident happened near the station. → Where did the accident happen?

事故在哪儿发生?

三、笔记整理

1.在变换句型时,首先确定句中的谓语动词是否含有 could/ should/ would/ was/ were,如果有,将其提到句首变为一般疑问句;其后加 not 构成否定句。

2.如果没有上述动词,就应借助于助动词 did,将其放在句首,动词用原形

构成一般疑问句;借助于助动词 didn’t,后接动词原形构成否定句。

3.特殊疑问句就是在分清上述情况后,前面加上特殊疑问词即可。

1.(浙江杭州) The last time I to the cinema was two years ago. A. go B. have gone C. have been D. went 答案:D

思路分析:根据句意“上次我去电影院的时间是两年前”可知时态用一般过去时。在本句中,I went to the cinema 作 last time 的定语。

2.(浙江金华) —Have you ever been to Canada?

—Yes, I there last year with my parents. A.have been B.have gone 答案:C

思路分析:根据答语中的过去时间状语 last year 可知时态用一般过去时。故选 C 项。句意为“—你曾去过加拿大吗?—是的。我是去年和我父母一块去的”。

3.(重庆) I called you, but nobody answered. Where you? A.is B.are C.was D.were 答案:D

思路分析:根据题干的前半句可知本题用一般过去时;you 是第二人称,故用 were。句意为“—我给你打电话,但是没人接。你在哪儿?”。

C.went

D.go
