as的用法小結(jié)

  英語(yǔ)是按照分布面積而言最流行的語(yǔ)言,但母語(yǔ)者數(shù)量是世界第三,僅次于漢語(yǔ)、西班牙語(yǔ)。它是學(xué)習(xí)最廣泛的第二語(yǔ)言,是近60個(gè)主權(quán)國(guó)家的官方語(yǔ)言或官方語(yǔ)言之一。下面為大家?guī)?lái)as的用法小結(jié),快來(lái)看看吧。

  as的用法小結(jié)

  1.Child as[though]he was, he did quite well. 他雖是個(gè)孩子,但已干得很不錯(cuò)。

  2. 用作關(guān)系代詞,主要用法有二。如:

  (1) 用在such, same, as等之后,引導(dǎo)限制性定語(yǔ)從句。如:

  This is thesame watch as I lost. 這塊表跟我丟失的那塊一樣。

  Such men as (=Those men who) heard of him praised him. 聽(tīng)說(shuō)過(guò)他的人都贊揚(yáng)他。

  (2) 單獨(dú)用作關(guān)系代詞,引導(dǎo)非限制性定語(yǔ)從句,可放在主句之前 (常譯為:正如)或之后 (常譯為:這一點(diǎn)),且主從句之間一般要用逗號(hào)隔開(kāi)。如:

  He was absent, as is often the case. 他缺席了,這是常有的事。

  As was expected, he succeeded at last. 正如我們所料,他終于成功了。

  3. 用來(lái)表示目的,下面兩種句子結(jié)構(gòu)都可以。如:

  仔細(xì)寫(xiě)以便把每句話都寫(xiě)清楚。

  正:Write carefully so as to make every sentence clear.

  正:Write so carefully as to make every sentence clear.

  4. 在正式文體 (尤其是文學(xué)體裁)中,as后可用倒裝語(yǔ)序表示“…也一樣”這類(lèi)意思 (現(xiàn)代英語(yǔ)通常so表示這一用法)。如:

  He travelled agreat deal, as did most of his friends. 他去過(guò)許多地方旅游,他的多數(shù)朋友也是一樣。

  He plays the piano, as does his mother. 他會(huì)彈鋼琴,他母親也會(huì)。

  注:用作連詞,表示原因 (參見(jiàn)because),表示時(shí)間 (參見(jiàn)when)。

  5. 用于 as if

  as though, 意為“仿佛”、“似乎”。兩者一般可通用 (但注意不能說(shuō) as although)。用法上注意幾點(diǎn):

  (1) as if [though] 可引導(dǎo)狀語(yǔ)從句和表語(yǔ)從句,從句謂語(yǔ)根據(jù)語(yǔ)義的要求,可用陳述語(yǔ)氣 (若可能為事實(shí))或虛擬語(yǔ)氣 (若為假設(shè)或不太可能是事實(shí))。如:

  It looks as if it is going to rain. 天似乎要下雨了。

  It seems as if you’re right. 似乎你是對(duì)的。

  He talks asthough he knew everything. 他夸夸其談,好像無(wú)所不知。

  When apencil is partly in a glass of water, it looks as if it werebroken. 當(dāng)把一支鉛筆的一部分放在一杯水里時(shí),它看起來(lái)好像折斷了似的。

  當(dāng)主句謂語(yǔ)是過(guò)去時(shí)態(tài)時(shí),從句謂語(yǔ)?捎藐愂稣Z(yǔ)氣。如:

  He pausedas though he found a difficulty. 他停了下來(lái),似乎遇到了一個(gè)難題。

  She felt as if she lost something. 他覺(jué)得似乎丟了什么東西。

  (2) 當(dāng)從句主語(yǔ)與主句主語(yǔ)一致,且從句謂語(yǔ)中又包括有動(dòng)詞be時(shí),從句主語(yǔ)及其謂語(yǔ)中的動(dòng)詞be通?梢允∪。如:

  From time to time heturned round as though (he was) searching for someone. 他不時(shí)地四下張望,好像在找人。

  He opened his mouth as if (he was)to speak. 他張開(kāi)口,好像要說(shuō)話似的。

  6. 關(guān)于 as…as, 用法注意:

  (1) 中間只能用形容詞或副詞的原級(jí),不能用比較級(jí)或最高級(jí)。如果在第二個(gè)as之后使用獨(dú)立的人稱(chēng)代詞,一般說(shuō)來(lái)用主格 (較正式)或賓格 (非正式)均可。如:

  He’s as old as she

  her. 他年紀(jì)跟她一樣大。

  注意:

  要是第二個(gè)as之后的人稱(chēng)代詞跟有謂語(yǔ)動(dòng)詞,則該人稱(chēng)代詞只能用主格。如:

  He is as old as she is.

  但是有時(shí)用主格或賓格含義差別很大。如:

  You love him as much as I (=as I love him). 你愛(ài)他像我愛(ài)他一樣。

  You love him as much as me (=as you love me). 你愛(ài)他像愛(ài)我一樣。

  (2) 在肯定句中用as…as, 在否定句中用not as…as或not so…as 均可。如:

  He doesn’t study as [so] hard as his brother. 他學(xué)習(xí)不如他弟弟努力。

  (3) 要注意比較對(duì)象的一致性,即比較的雙方必須是可以比較的的同類(lèi)人或物,否則會(huì)出錯(cuò)。如:

  正:The population of China is much larger than that of Japan. 中國(guó)人口比日本人口多得多。

  誤:The population of China is much larger than Japan.

  (此句錯(cuò)在將 the population of China 與 Japan 來(lái)比較,比較對(duì)象不一致)

  (4) 如果涉及數(shù)量或程度,可用以下兩個(gè)結(jié)構(gòu)。如:

 、賏s much+ (不可數(shù)名詞+) as

 、赼s many+ (可數(shù)名詞復(fù)數(shù)+) as

  You must speak English as much as possible. 你必須盡可能地多說(shuō)英語(yǔ)。

  You’ve made as many mistakes as I have. 你犯的錯(cuò)誤和我犯的一樣多。

  (5) 請(qǐng)注意下列結(jié)構(gòu)的詞序。如:

  她和她媽媽一樣是位好廚師。

  正:She is a cook as good as her mother.

  正:She is as good a cook as her mother.

  誤:She is as a good cook as her mother.

  (6) 修飾as…as結(jié)構(gòu)的常見(jiàn)詞語(yǔ)有nearly, almost, just, exactly, half, quite, twice, three times等,請(qǐng)注意這些修飾語(yǔ)都只能放在as…as 結(jié)構(gòu)之前 (而不能置于其中或其后。如:

  This rope is twice aslong as that one. 這根繩子比那根長(zhǎng)一倍。

  (7) as…as結(jié)構(gòu)的下列用法,屬于“異質(zhì)比較” (注:主、從句的主語(yǔ)和謂語(yǔ)一致時(shí),從句的主語(yǔ)和謂語(yǔ)有時(shí)可以省略)。如:

  The room is aslong as (it is) wide. 這房間的長(zhǎng)寬尺寸一樣。

  The news was asunexpected as (it was) welcome. 這消息來(lái)得突然,但受人歡迎。

  She is as clever as (she is) beautiful. 她既聰明又漂亮。

  Oneis as light as the other is heavy. 一個(gè)輕,另一個(gè)重。

  (8) as…as結(jié)構(gòu)在一定的上下文中可以用其省略結(jié)構(gòu) (即省去其中的一個(gè) as)。如:

  She’s clever, but her brother is just as clever. 她很聰明,但她兄弟也一樣聰明。

  The woman married a man pooras herself. 這個(gè)女人嫁給了一個(gè)與她一樣窮的男人。
