狀語從句讓很多同學(xué)感到頭疼，不知如何下手。以下是小編整理的狀語從句用法解析，希望對(duì)你有所幫助

一、in case引導(dǎo)的狀語從句

根據(jù)語境的不同，in case既可表示“如果”“萬一”，引導(dǎo)條件狀語從句;也可表示“以防(萬一)”，引導(dǎo)目的狀語從句。下面兩道真題均選in case：

1. Leave your key with a neighbor ______ you lock yourself out one day. (北京卷)

A. ever since B. even if C. soon after D. in case

2. My parents live in a small village. They always keep candles in the house ______ there is a power cut. (重慶卷)

A. if B. unless C. in case D. so that

【解析】?jī)傻李}都選in case，均表示“以防萬一”。

二、before引導(dǎo)的狀語從句

尤其要注意“it+be+一段時(shí)間+before…”這一句型。如：

1. The field research will take Joan and Paul about five months; it will be a long time ______ we meet them again. (安徽卷)

A. after B. before C. since D. when

2. He was told that it would be at least three more months ______ he could recover and return to work. (江西卷)

A. when B. before C. since D. that

【解析】?jī)傻李}均before。第1題涉及的句式為：It will be a long time before…，意思是“要過很久才會(huì)……”;第2題涉及的句式為：it was some time before…，意思是“在……之前過了一段時(shí)間”，通?？赊D(zhuǎn)譯為“要過一段時(shí)間才會(huì)……”。

三、while引導(dǎo)的狀語從句

尤其要注意while表示“盡管”“雖然”時(shí)的用法(此時(shí)它引導(dǎo)的不是時(shí)間狀語從句，而是讓步狀語從句——此用法許多同學(xué)并不熟悉，值得特別注意!)。如：

______ I really don’t like art, I find his work impressive. (山東卷)

A. As B. Since C. If D. While

【解析】答案選D。while在此表示“盡管”“雖然”，又如：While the work was difficult, it was interesting. 盡管工作有難度，但很有趣。/While I understand what you say, I can’t agree with you. 雖然我理解你的意思，但我還是不同意。

另外，while表示對(duì)比的用法也值得注意(此時(shí)它表示“而”)。如：

The cost of living in Glasgow is among the lowest in Britain, ______ the quality of life is probably one of the highest. (天津卷)

A. since B. when C. as D. while

四、when引導(dǎo)的狀語從句

對(duì)于when的`用法，同學(xué)們最熟悉的是表示“當(dāng)……的時(shí)候”。如：

—Where’s that report?

—I brought it to you ______ you were in Mr. Black’s office yesterday. (北京卷)

A. if B. when C. because D. before

【解析】答案選B。將四個(gè)選項(xiàng)逐一填入空格處，只有填when時(shí)，意思最通順。句意為：當(dāng)你昨天在布萊克先生辦公室時(shí)我就帶給你了。

但是when還有一個(gè)用法，就是表示“既然”。如：

Why do you want a new job ___D___ you’ve got such a good one already?

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

還有一點(diǎn)也需注意，就是when表示“這時(shí)(突然)”的用法。如：

1. I had just stepped out of the bathroom and was busily drying myself with a towel ___B___ I heard the steps. (湖南卷)

A. while B. when C. since D. after

2. He was about halfway through his meal ___C___ a familiar voice came to his ears. (遼寧卷)

A. why B. where C. when D. while

AS在定語從句中的用法

as...as意為"和……一樣"，表示同級(jí)的比較。使用時(shí)要注意第一個(gè)as為副詞，第二個(gè)as為連詞。例如：

我們要盡量少犯錯(cuò)誤

1.we should make a few mistakes.

2.we should avoid mistakes.

3.we should make (as) a few mistakes.

4.(as) we should (avoid mistakes)

5.we should make as a few mistakes as we should.

我們要盡量多吃蔬菜

1.we should eat much vegetable food.

2.we should eat the food.

3.we should eat (as ) vegetable food.

4.(as) we should (eat the food).

5.we should eat as vegetable food as we should.

the same~~as~~

他不再是我認(rèn)識(shí)的那個(gè)花花公子。

1.he is not the playboy.

2.i know the boy years ago.

3.he is not the (same) playboy.

3.(as) I know (the boy) years ago.

5.he is not the same playboy as i know.
