關(guān)系代詞引導(dǎo)的定語從句

關(guān)系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當(dāng)主語、賓語、定語等成分。關(guān)系代詞在定語 從句中作主語時(shí)，從句謂語動(dòng)詞的人稱和數(shù)要和先行詞保持一致。

狀語從句 （Adverbial Clause）

狀語從句指句子用作狀語時(shí)，起副詞作用的句子。它可以修飾謂語、非謂語動(dòng)詞、定語、狀語或整個(gè)句子。

根據(jù)其作用可分為時(shí)間、地點(diǎn)、原因、條件、目的、結(jié)果、讓步、方式和比較等從句。狀語從句一般由連詞(從屬連詞)引導(dǎo)，也可以由詞組引起。從句位于句首或句中時(shí)通常用逗號(hào)與主句隔開，位于句尾時(shí)可以不用逗號(hào)隔開。

時(shí)態(tài)特點(diǎn)

一般情況下，時(shí)間和條件狀語從句的謂語動(dòng)詞一般用“一般現(xiàn)在時(shí)”表示“一般將來時(shí)”，用“現(xiàn)在完成時(shí)”表示“將來完成時(shí)”。

例如：

I will call you as soon as I arrive in Beijing. 我到北京就將給你打電話。

(這是由as soon as引導(dǎo)的時(shí)間狀語從句，從句中的謂語動(dòng)詞arrive是一般現(xiàn)在時(shí)，表示一般將來時(shí)，絕不可用will arrive)

As soon as I have finished this work, I will have gone home. 我一完成此工作，就回家。

(從句中的謂語動(dòng)詞用現(xiàn)在完成時(shí)have finished，表示將來完成時(shí),絕不可用will have finished)

If he comes back, please let me know.如果他回來了，請(qǐng)通知我。

(從句中的謂語動(dòng)詞用comes back,表示一般將來時(shí)，絕不可用will come back)

從句通常結(jié)構(gòu)：主 do sth.\do sb.(條件)+ V.\結(jié)果

狀語從句同時(shí)具備下列兩個(gè)條件:①主句和從句的主語一致，或從句主語為it;②從句主要?jiǎng)釉~是be的某種形式。從句中的主語和be動(dòng)詞常可省略。例如：

就狀語從句而言,有時(shí)為了使語言言簡意賅,常常將狀語從句進(jìn)行"簡化"。狀語從句的"簡化"現(xiàn)象在口語中較為普遍,而且在高考中的復(fù)現(xiàn)率也較高。因此,有必要對(duì)其進(jìn)行全面、透徹的了解。

狀語從句的"簡化"現(xiàn)象常存在于以下五種狀語從句中:

①由if, unless等引導(dǎo)的條件狀語從句;

②由although, though, even if / though等引導(dǎo)的讓步狀語從句;

③由when, while, as, before, after, until / till等引導(dǎo)的時(shí)間狀語從句;

④由as, as if等引導(dǎo)的方式狀語從句;

⑤由as, than等引導(dǎo)的比較狀語從句。下面針對(duì)這五種情形作一歸納。

(1)當(dāng)狀語從句的主語是it,且謂語動(dòng)詞是be時(shí),it和be要完全簡化掉。

例如:

If (it is) possible, he will help you out of the difficulty.

如果可能的話,他會(huì)幫你擺脫困境。

You must attend the meeting unless (it is) inconvenient to you。

除非情況對(duì)你來說不方便,否則你必須出席這次會(huì)議。

(2)當(dāng)狀語從句的主語和主句的主語一致時(shí),從句可以將主語和be動(dòng)詞簡化掉。常用于以下幾種情形:

連詞+形容詞

As (he was) young, he learned how to ride a bike.

他小時(shí)候就學(xué)會(huì)了騎自行車。

Whenever (she is) free, she often goes shopping.

Although (he is) doing his best in maths these days, he has still got no good marks.

盡管近來他一直在學(xué)數(shù)學(xué),但他仍然沒有取得好成績。

連詞+過去分詞

除非受到邀請(qǐng),否則他不會(huì)和我們一道去那里。

.這場(chǎng)音樂會(huì)出乎意料地取得了巨大成功。

連詞+不定式

當(dāng)時(shí)他站起來好像要說什么。

He wouldn't solve the problem even if (he were) to take charge.

即使他來負(fù)責(zé),他也解決不了這個(gè)問題。

連詞+介詞短語

她看上去很焦急,好像遇到了麻煩。

他到美國之前就懂英語了。

注意:當(dāng)從句主語和主句主語不一致時(shí),從句部分要么用完全形式,要么用獨(dú)立主格結(jié)構(gòu)來表達(dá)。

例如:

When the meeting was over, all the people went out of the meeting-room.

當(dāng)會(huì)議結(jié)束時(shí),人們都走出了會(huì)議室。(=The meeting over)
