精講精練——狀語從句

【知識點】

考查狀語從句中連詞的選擇，特殊句式，從句的時態(tài)語態(tài)，以及狀語從句的省略。

【高考考向】

狀語從句是中學(xué)英語教學(xué)的重點，也是學(xué)生學(xué)習(xí)的難點，狀語從句是一個較大的語法項目，也是近幾年高考試題中常見的一個重要考點。完形填空，語法填空，書面表達都可考察此項語法。

準確掌握每一個連詞的含義是掌握狀語從句的關(guān)鍵，同時要注意主從句的時態(tài)呼應(yīng)。

概念以及句型特點

(1)概念：狀語從句在復(fù)合句中作狀語，修飾主句中的動詞、形容詞、副詞等。

(2)句型特點：

狀語從句可以放在主句之前，也可以放在主句之后。放在主句之前時，常用逗號與主句分開；放在主句之后時，不用逗號。

一、時間狀語從句

1. when，while和as引導(dǎo)的時間狀語從句

While some people are motivated by a need for success，others are motivated by a fear of failure.

盡管有些人被成功的渴望所激勵，但也有一些人卻被失敗的恐懼所激發(fā)。

2. 表示“一……就……”的連詞引導(dǎo)的時間狀語從句

(1)as soon as，the moment，the minute，the instant，immediately，directly, each time, every time, the first time

The moment my aunt gained her diploma after four years of hard work，she was filled with joy.我阿姨苦讀四年之后獲得了文憑，那一刻她欣喜萬分。

(2)在hardly...when...，no sooner...than...結(jié)構(gòu)中，主句用過去完成時，than或when所在的從句用一般過去時。

I had hardly got to the office when my wife phoned me to go back home at once.

3. before，since引導(dǎo)的時間狀語從句

(1)before表示“在……之前；還未……就……；還沒有來得及……就……”。常用句式：①It will be/was＋一段時間＋before...過了……時間才……；②It won't be/wasn't＋一段時間＋before...沒過多久就……。

We need to get to the root of the problem before we can solve it.

(2)since意為“自從……以來”，常用句式：It is/has been＋一段時間＋since從句(常用過去時)。since從句的時態(tài)若是一般過去時，主句的時態(tài)常用現(xiàn)在完成時或現(xiàn)在完成進行時。

4. till/until引導(dǎo)的時間狀語從句

She didn't start the lesson until the pupils settled down.

5. every time，each time，next time，the first time，by the time等引導(dǎo)的時狀

By the time you have finished this book，your meal will get cold.

二、讓步狀語從句

1. although，though，as和while引導(dǎo)的讓步狀語從句

(1)though引導(dǎo)的從句可用倒裝語序，也可不倒裝；although引導(dǎo)的從句不倒裝；as引導(dǎo)的從句必須用倒裝語序。

Although these measures are not effective forever，they are vital for now.

雖然這些措施并不能永遠有效，但它們目前是至關(guān)重要的。

Hot as/though the night air was，we slept deeply because we were so tired after the long journey.

夜晚的空氣雖然很熱，但因為長途旅行之后很累，我們睡得很沉。

(2)though可用作副詞，意為“然而”，表轉(zhuǎn)折，置于句末。

(3)while引導(dǎo)讓步狀語從句，只能置于句首。

(4)as、though引導(dǎo)讓步狀語從句時采用倒裝的兩種特殊情況：

①如果是單數(shù)名詞或形容詞的最高級作表語，不再用冠詞。

Youngest as/though he is in our class，he speaks English best.

②行為動詞前置時，從句主語后面要用may，might，can，could，will，would等情態(tài)動詞，若沒有情態(tài)動詞，則需加上一個do(does或did)。若前置的行為動詞是及物動詞，則其賓語也隨其后一并提前。

Search as they would here and there，they could find nothing in the room.

2. even if與even though 引導(dǎo)的讓步狀語從句

even if/even though引導(dǎo)讓步狀語從句時，表示語氣更強的讓步，意為“即使，即便”。

Tim is in good shape physically even though/even if he doesn't get much exercise.

3. “疑問詞＋-ever”引導(dǎo)的讓步狀語從句

where(what，who，whom，when，which，how)＋-ever表示“無論……”，引導(dǎo)讓步狀語從句時，相當(dāng)于no matter where(what，who，whom，when，which，how)。

It is generally considered unwise to give a child whatever he or she wants.

4. whether...or...引導(dǎo)的讓步狀語從句

whether...or...意為“無論……還是……”，提供兩種對比情況。

All people，whether they are old or young，rich or poor，have been trying their best to help those in need since the disaster.

三、其他狀語從句

【技法點撥】

在語法填空中, 狀語從句的考查集中在連詞的使用上。解題時要認真分析主、從句之間的邏輯關(guān)系，明確從句表示時間、地點、條件、原因、讓步、方式、比較等，再根據(jù)各種從句固定使用的連接詞確定正確答案。

【學(xué)生學(xué)情分析】

學(xué)生在近期的學(xué)習(xí)中暴露的主要問題是不能精準識別狀語從句，分不清幾大從句的區(qū)別，說明對句式定義把握不準，翻譯能力還不夠，固定搭配和短語記不牢，需要多加練習(xí)。

【建議變式練習(xí)】
