　　復(fù)雜句中as用法總結(jié)

　　一、as作為從屬連詞，引導(dǎo)讓步狀語(yǔ)從句

　　as引導(dǎo)讓步狀語(yǔ)從句比較特別，它要求將主語(yǔ)和謂語(yǔ)或謂語(yǔ)的一部分倒裝。如：Old as he is, he is still full of energy. 盡管年紀(jì)大了，但他依然精力充沛。Try as she may, she never succeeds. 盡管她很努力，但總是不成功。Try as she may, she never succeeds. Much as I admire Mr. Wang as a poet, I don’t like him as a man. 盡管我喜歡王先生的詩(shī)歌，但我不喜歡他的為人。注：當(dāng)?shù)寡b后置于句首的名詞為單數(shù)可數(shù)名詞時(shí)，習(xí)慣上不帶冠詞。如：Boy as he was, he was made king. 盡管他還是個(gè)孩子，卻被立為國(guó)王了。

　　二、as作為從屬連詞引導(dǎo)時(shí)間狀語(yǔ)從句

　　表示“當(dāng)……的時(shí)候”或“>一邊……一邊”，強(qiáng)調(diào)主句的動(dòng)作和從句的動(dòng)作同時(shí)發(fā)生。如：I saw him as he was getting off the bus. 當(dāng)他下公共汽車的時(shí)候我看見了他。The boy was singing a popular song as he was bicycling. 這男孩邊騎車邊唱歌。As she grew older, she became less active. 當(dāng)她長(zhǎng)大一點(diǎn)的時(shí)候，就變得不那么活潑了。As she grew older, she became less active.

　　三、as作為從屬連詞引導(dǎo)原因狀語(yǔ)從句

　　as 引導(dǎo)的原因狀語(yǔ)從句常放在主句前，表示“因?yàn)?，由?rdquo;。如：As she is a model teacher, she gives a good example to others. 因?yàn)樗且幻７督處煟o其他人樹立了一個(gè)好的典范。As he wasn’t ready in time, we went to the cinema without him. 由于他沒(méi)有及時(shí)準(zhǔn)備好，我們就去看電影了，沒(méi)有等他。

　　三、as用作關(guān)系代詞引導(dǎo)定語(yǔ)從句

　　1. as 引導(dǎo)非限制性定語(yǔ)從句，一般不指代某個(gè)具體的名詞或代詞，而是代表整個(gè)主句或主句的一部分。這種從句可放在主句之前，也可以放在主句之后，有時(shí)還可以放在主句的中間。如：As is reported in the newspapers, talks between the two countries are making progress. 正如在報(bào)紙上所報(bào)道的，兩國(guó)間的談判有所進(jìn)展。Grammar is not a set of dead rules, as has been said above. 如上所說(shuō)，語(yǔ)法不是一套死條文。Spiders are not insects, as many people think, nor even nearly related to them.蜘蛛不是昆蟲，盡管許多人都這樣認(rèn)為，它甚至與昆蟲幾乎沒(méi)有聯(lián)系。2. as 引導(dǎo)限制性定語(yǔ)從句，主要用于the same…as(與……相同)，such…as(像……一樣)，as…as(與……一樣)。如：(與She knew he felt just the same as she did. 她知道他的感受和她一樣。Such a man with a good temper as Mr. Li is easy to get along with. 像李先生這樣好脾氣的人是容易相處的。He smokes as expensive a cigarette as he can afford. 他抽一種他買得起的最貴的煙。

　　四、與其他詞搭配使用構(gòu)成從屬連詞引導(dǎo)從句

　　1. as if / as though。表示 “好像，仿佛”，引導(dǎo)表語(yǔ)從句或方式狀語(yǔ)從句。如：It looks as if / as though it is going to snow. 看起來(lái)要下雪啦。He looks as if / as though he had seen a ghost. 他的臉色看起來(lái)好像他看見了鬼。He talks as if /as though he knew everything about it. 他說(shuō)話的口氣好像他已經(jīng)全部都知道了。< it. about everything>

　　2. as [so] long as。“只要”，引導(dǎo)條件狀語(yǔ)從句。如：< it. about everything>As [So] long as you can keep away from them, you will be safe. 只要你能遠(yuǎn)離他們，你就安全了。I’m happy as long as you are happy. 只要你幸福，我就感到幸福了。I’m happy as long as you are happy.

　　3. as [so] far as。表示“在……的范圍內(nèi)”，引導(dǎo)限制狀語(yǔ)從句。多用于下列結(jié)構(gòu)：as [so] far as I know(據(jù)我所知)，as [so] far as I can see, as [so] far as I’m concerned(依我看)。如：(依我看)。如：As [So] far as I know, the couple have been abroad for about five years. 據(jù)我所知，這對(duì)夫婦已經(jīng)出國(guó)約五年了。There’s only one thing to be done now, as far as I can see. 依我看?，F(xiàn)在只有一件事情要做。

　　4. as soon as。表示“一……就”，引導(dǎo)時(shí)間狀語(yǔ)從句。如：As soon as he got off the plane, he telephoned her girl friend. 他一下飛機(jī)就給他的女朋友打了個(gè)電話。He started as soon as he received the news. 他一得到消息就出發(fā)了。

　　總之，由于as的用法復(fù)雜，同學(xué)們?cè)趯W(xué)習(xí)時(shí)一定要注意比較其在不同句子中的作用，判斷其連接的是什么樣的從句，多做一些關(guān)于相關(guān)練習(xí)，這樣便可掌握其用法了。
