語法篇:狀語從句用法解析

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


(資料圖片)

一、in case引導的狀語從句

根據語境的不同,in case既可表示“如果”“萬一”,引導條件狀語從句;也可表示“以防(萬一)”,引導目的狀語從句。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】兩道題都選in case,均表示“以防萬一”。

二、before引導的狀語從句

尤其要注意“it+be+一段時間+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】兩道題均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……”;第2題涉及的句式為:it was some time before…,意思是“在……之前過了一段時間”,通??赊D譯為“要過一段時間才會……”。

三、while引導的狀語從句

尤其要注意while表示“盡管”“雖然”時的用法(此時它引導的不是時間狀語從句,而是讓步狀語從句——此用法許多同學并不熟悉,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表示對比的用法也值得注意(此時它表示“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引導的狀語從句

對于when的`用法,同學們最熟悉的是表示“當……的時候”。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。將四個選項逐一填入空格處,只有填when時,意思最通順。句意為:當你昨天在布萊克先生辦公室時我就帶給你了。

但是when還有一個用法,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

還有一點也需注意,就是when表示“這時(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",表示同級的比較。使用時要注意第一個as為副詞,第二個as為連詞。例如:

我們要盡量少犯錯誤

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~~

他不再是我認識的那個花花公子。

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.

as引導讓步狀語從句

結構: n./ v.原型 / adj. / adv. + as + 其他

1. adv. 提前:

Although he failed in doing his experiment again, he didn’t lose heart.

Again as he failed in doing his experiment, he didn’t lose heart.

2. adj. 提前:

Although the necklace was beautiful, we thought it was over-priced.

Beautiful as the necklace was, we thought it was over-priced.

3. n. 提前:

Although she is a child, she is knowledgeable.

Child as she is, she is knowledgeable.

單數可數名詞前一般不帶冠詞

4. v. 提前:

Although I failed, I would never stop trying.

Fail as I did, I would never stop trying.

Try as I may, I could never explain what I hear when you don’t say a thing.

Although we may dislike him, we have to acknowledge his greatness.

Dislike him as we may, we have to acknowledge his greatness.

動賓短語同時提前
