有關(guān)“疑問(wèn)詞”的語(yǔ)法陷阱題

一、“疑問(wèn)詞”用于介詞后

【經(jīng)典實(shí)例】

Children rarely show any appreciation for _________ their parents do for them.

A. which                     B. how                     C. what                      D. why

【解析】選C。what引導(dǎo)的賓語(yǔ)從句用作介詞for的賓語(yǔ)，同時(shí)what在賓語(yǔ)從句中用作動(dòng)詞do的賓語(yǔ)。

【類似例句】

With whom did you go? 你和誰(shuí)一起去的?

To whom were you speaking? 你剛才在跟誰(shuí)說(shuō)話?

Since when have you became active? 你什么時(shí)候開(kāi)始變得積極了?

For what purpose did you invite me to come here? 你們請(qǐng)我到這里來(lái)是為了什么目的?

What was her explanation for why she was late? 她對(duì)她的遲到有何解釋？

二、省略后只保留“疑問(wèn)詞”

【經(jīng)典實(shí)例】

Dr. Black comes from either Oxford or Cambridge, I can’t remember _________.

A. where                     B. there                     C. which                     D. that

【解析】選C。I can’t remember which為I can’t remember which city he comes from之省略。

【類似例句】

I have seen you before, but I can’t remember where. 我以前見(jiàn)過(guò)你，但是不記得在哪里了。

He would have preferred to put her idea aside together, if he had known how. 如果他已經(jīng)知道情況，他寧愿把她一古腦兒拋到一邊。

Become a successful writer. This book shows you how. 要想成為一名成功的作家。這本書告訴你如何實(shí)現(xiàn)你的理想。

Something is the matter, but I don’t know what. 總有點(diǎn)不對(duì)勁，但我不知道是什么。

He has turned against his wife. He himself doesn’t know why. 他和妻子作對(duì)。他自己也不知為什么。

She’s got a down on me; I don’t know why. 她很討厭我，我不知道為什么。

三、兩個(gè)或多個(gè)“疑問(wèn)詞”連用

【經(jīng)典實(shí)例】

Professor James will give us a lecture on the Western culture, but when and where _________ yet.

A. hasn’t been decided    B. haven’t decided       C. isn’t being decided     D. aren’t decided

【解析】A。根據(jù)句意，此處應(yīng)用被動(dòng)語(yǔ)態(tài)，不用主動(dòng)語(yǔ)態(tài)，故排除B；又因?yàn)?/FONT>when and where表示單數(shù)意義，故排除D；再根據(jù)句末的yet可知，最好用現(xiàn)在完成時(shí)，故選A最佳。
