2015年職稱英語考試常用語法詳解:狀語從句

來源:本站原創(chuàng) 更新:2014/8/13 職稱英語考試論壇

狀語從句

  所謂狀語從句,是指用來說明主句行為(或狀態(tài))發(fā)生的時(shí)間、原因、條件、地點(diǎn)、目的、結(jié)果及方式等。

  1) 時(shí)間狀語從句:記住以下連接詞的意思和重點(diǎn):

  (1)when / while / as (當(dāng)…時(shí)侯)

  注意:while除了做時(shí)間狀語的連接詞外,還解釋為"雖然…","而…".

  例如:He is very diligent, while she is very lazy. (他很勤奮,而她卻很懶。)

  (2)before (after) 在…之前(后)

  (3)until / not until(直到)注意:not until放在句首時(shí),往往要求倒裝(詳見"第七講")

  (4)as soon as / once (一…就…)

  (5)immediately / instantly / directly 原本是副詞,這里作連接詞,表示"一…就…",

  例如: I knew I had made a mistake directly (或用immediately / as soon as) I had done it. (剛做完這件事,我就知道我做錯(cuò)了。醫(yī),學(xué).全.在.線.提供)

  (6)the moment / each time / every time / next time / the first time / the instant / the year原本是名詞或副詞,這里作連接詞用。

  (7)hardly (scarcely)…when… / no sooner…than…"一…就…"

  注意:這是時(shí)間狀語考試的重點(diǎn)句型,一是不要把兩個(gè)句型中的when和than的搭配搞錯(cuò)了,二是要用倒裝語序(詳見"第七講")。

  例如:

  Hardly had I sat down when the telephone rang. (我剛坐下,電話鈴就響了。)

  重點(diǎn):在時(shí)間(和條件)狀語中,用一般時(shí)代替將來時(shí)。

  例如:

  We'll start as soon as the leader ______. (領(lǐng)導(dǎo)一來就開始。)

  A.comes   B.is coming  C.will come   D.came

  根據(jù)英語"時(shí)態(tài)一致性"原則,主句與從句的時(shí)態(tài)應(yīng)一致,答案似乎應(yīng)該是B或C,但是正確答案是A,因?yàn)樵跁r(shí)間狀語中,用一般時(shí)代替將來時(shí)。將上句改為過去時(shí),道理也一樣:

  He said (that) we would start as soon as the leader _____.

  A.came   B.was coming   C.would come   D.comes

  答案應(yīng)為A

  2) 條件狀語從句:分真實(shí)條件句和非真實(shí)條件句(虛擬語氣)

  重點(diǎn):在條件(時(shí)間)狀語中,用一般時(shí)代替將來時(shí)(可參見時(shí)間狀語從句例子)

  虛擬語氣(見"第六講")

  主要連接詞:

  (1)if / unless (除非 = if not 如果不)

  例如:

  Children should not be taken into the room of a very sick person ______ there is some special reason for it.

  A.except   B. besides   C. unless  D.whereas

  解題思路:根據(jù)上面說過的連接原則,這里必須是一個(gè)"連接詞",而A,B都是介詞,因此正確答案只能在C,D中選。"whereas"意為"而",故正確答案為C.(不應(yīng)把兒童帶到重病人房間,除非有某種特殊原因。)

  (2)provided / on condition that (跟句子) (如果…)知道這也是連接詞就可以了,一般說,當(dāng)考題中出現(xiàn)這種詞時(shí),應(yīng)傾向選擇。

  3) 原因狀語從句:

  主要連接詞:because/ since / as

  要點(diǎn):不要把連接詞 because與介詞短語because of ( + 名詞或-ing形式) 相混淆;

  不要把表示原因的since與表示時(shí)間的since"自從…"相混淆;

  不要把表示原因的as與表示時(shí)間的as"隨著…"相混淆;

  順便提一下, because表示直接"因果關(guān)系",而since, as 是對(duì)事實(shí)的說明,主句和從句之間并不一定具有"因果關(guān)系".

  例如:

  As you are already 18 years old, you should know what to do and what not to do. (你已經(jīng)18歲了,應(yīng)該知道什么該干什么不該干。)

  這個(gè)句子用because連接就不太合適。好在軍隊(duì)職稱考試中并不要求作這種分辨。

  …for 注意:一般只能放在主句后面,即主句 + for從句,例如:

  He must have gone to bed, for it is too late. (他肯定已經(jīng)睡了;現(xiàn)在已經(jīng)很晚了。)—— 該句不能用because

  now that / seeing that / considering that (由于…)

  Seeing that this problem was settled, they proceeded to the next one.(鑒于這個(gè)問題已經(jīng)解決,他們開始進(jìn)行下一個(gè)問題。) n

  …in that(在于…)一般放在主句后面,例如:

  Humans are superior to animals in that they can use languages as a tool to communicate. (人比動(dòng)物高等,因?yàn)槿四芤哉Z言作為工具進(jìn)行交際。)
 4) 讓步狀語從句:

  主要連接詞:although (雖然)/ even if (though) (即使)/ while (盡管)后兩個(gè)是考試的重點(diǎn)。no matter what… (= whatever無論…什么…) / no matter how… (=however, 無論怎樣…) / whether…or not (不論…還是…)這是讓步句考試的重點(diǎn)。

  例如:

  No matter what (或Whatever) may happen, we will not change our plan. (無論可能發(fā)生什么,我們決不改變計(jì)劃。)

  No matter how difficult (或However difficult) the journey may be, we will not change our plan. (不管路程有多難,我們決不改變計(jì)劃。)

  We should not worry her whether she is well or ill (或whether she is ill or not).(無論她身體好壞,我們都不應(yīng)使她煩惱。)

  注意:no matter what后面跟名詞或名詞性結(jié)構(gòu);no matter how后面跟形容詞或副詞,不要搞錯(cuò);用了no matter what / no matter how就不能再用whatever / however.

  5) 比較狀語從句:

  這是英語語法必考內(nèi)容,要特別加以重視。

  基本概念:兩個(gè)比較級(jí),三個(gè)或三個(gè)以上最高級(jí)。要對(duì)數(shù)字"2"特別敏感,試選擇:

  Of Mary and Jane, who is ______?

  A. smart          B.the smartest

  C. more smarter      D.the smarter

  解題思路:很顯然這是一道考形容詞比較級(jí)的題目,從句子結(jié)構(gòu)和選題A可以判斷smart是個(gè)形容詞原級(jí),因此可以斷定C的形式錯(cuò)了(重復(fù)比較,如不能說more happier 一樣的道理)。B是最高級(jí),但句中只有兩個(gè)人Mary 和Jane,因此正確答案只能是D,這是一個(gè)較特殊的比較級(jí)句型,即the + 形容詞比較級(jí) + of (兩個(gè))。

  比較級(jí)的主要句型:

  (1) 原級(jí)比較:as +形容詞或副詞原級(jí)+ as, 否定式:not so (或as) +形容詞或副詞原級(jí)+ as

  注意問題:as…as 之間的形容詞或副詞是否采用了原級(jí);as…as 之間該用形容詞還是副詞;用as much as 還是用as many as

  表示倍數(shù)時(shí)用下面結(jié)構(gòu), 如3倍:three times as …as…

  例如:

  The size of the island is about ______ that of this one.

  A.three times as much as    B.as three times much as

  C.as three times greater than   D.three times as big as

  解題思路:B、C違反了上述句型規(guī)定,A、D的區(qū)別是size(大小 / 尺寸)是與much搭配還是與big搭配,D是對(duì)的。

  (2) 比較級(jí):more …than…

  注意:

  1) 比較形式是否正確,如是否有類似"more better"這樣重復(fù)比較的錯(cuò)誤;

  2)兩者之間是比較級(jí),三者以上是最高級(jí),看看是"兩者"還是"三者或三者以上;

  3)只有同類的人或物才能比較(可比性);比較不能包括"自己", 常用other表示排除。

  例如不能說:

  He is taller than any students in this class.

  而應(yīng)說:

  He is taller than any other student(s) in this class.

  4)修飾比較級(jí)的詞有:much, even, far, by far, still, a lot, a bit 等,例如:

  John did badly in the sports meet. I did even worse (than John did).

  你能看出下句的問題嗎?

  His salary as a bus driver is more higher than a teacher. ( 他是個(gè)公共汽車司機(jī),他的工資要比教師高。)

  該句有兩個(gè)大錯(cuò)1)high的比較級(jí)為higher,2)主語his salary(他的工資)而比較對(duì)象是a teacher,兩者不可比,怎樣的表達(dá)才是對(duì)的呢?請(qǐng)選擇:

  His salary as a bus driver is much higher ______.

  A.in comparison with a teacher  B.than a teacher

  C.than a teacher's        D.than that of a teacher's

  正確答案是C,也可以寫成than that of a teacher(請(qǐng)聯(lián)系名詞格的概念想一想)

  最高級(jí)the most of +比較范圍 / 最高級(jí)+名詞+that (不是which)定語從句,例如:

  This is the most interesting film that I have ever seen. (這是我看過的最有趣的電影。)

  the more…the more…

  The longer you wear glasses, the more you depend on them. (眼鏡戴的時(shí)間越長越有依賴性。)

  考試時(shí),一般只要認(rèn)準(zhǔn)"the" 和比較級(jí)形式就不難判別。

  其他表示比較意思的形式

  A is superior / inferior to B(A 比B高級(jí) / 低級(jí))

  注意:superior/ inferior前不能再加 more 或者less; 用to不是用 than.

  例如:

  Humans are superior to animals in that they can use languages to communicate.(人比動(dòng)物高級(jí)在于人能用語言進(jìn)行交際。)

  prefer… rather than (寧可…而不…)

  例如:

  I preferred to stay out in the cold rather than spend the night there. (我寧可呆在外面受冷,也不在那兒過夜。)

  Would rather…than… ……(用法和意思與上句型差不多)

  6) 地點(diǎn)狀語從句:

  主要連接詞:where / wherever / everywhere

  注意地點(diǎn)狀語從句中where與定語從句中關(guān)系副詞where的區(qū)別與聯(lián)系:

  Put the book where it is. (把書放好,即"把書放在該放的地方。)

  Put the book in the place where it is.

  以上兩個(gè)句子的意思是一樣的,第一個(gè)句子是"地點(diǎn)狀語從句",第二個(gè)句子是"定語從句"(詳見"第四講"),where作關(guān)系副詞修飾the place

  7) 方式狀語從句:

  as按時(shí)(正如…/ 就象…)

  Air is to man as water is to fish.

  要點(diǎn):不要把a(bǔ)s 與like 混淆,like是介詞,不是連接詞, 如不能說:All plants need air like they need water,應(yīng)為:All plants need air as they need water. (所有的植物需要空氣,正如他們需要水一樣。)

  as if / as though(好象…)可以是真實(shí)的,也可以是"虛擬"的,如:

  The meat tastes as if (though) it has already gone bad.(這肉吃起來好象變質(zhì)了。—— 確實(shí)壞了)

  He speaks English as though (if) he were an Englishman. (他說起英語來好象英國人。—— 他不是英國人,動(dòng)詞用的是were)

  8)目的 / 結(jié)果狀語從句

  目的狀語從句:

  so that / in order that

  lest / for fear that (惟恐… / 一以免…) 注意:該句型一般使用"should型"虛擬式(見"第六講")

  結(jié)果狀語從句:

  so…that / such…that…/ so that / that / so

  The professor speaks so fast that we find it difficult to follow him. (這位教授講話很快,我們感到很難理解他講話的意思。要點(diǎn):so + 形容詞或副詞)

  He give me such good advice that I finished the task smoothly. (他給了我很好的建議,因此我順利地完成了任務(wù)。要點(diǎn):such + 名詞)

  The film was such that everyone was deeply moved. (這部電影如此精彩,每個(gè)觀眾都被深深打動(dòng)了。要點(diǎn):such在這里做代詞,可以理解為:The film is such a good film that…)

  順便提一下,"…,only to do…" 雖不屬于從句,但是是一個(gè)重要的表 (意想不到的) 結(jié)果的句型,請(qǐng)記住, 例如:

  For nearly three hours we waited for the decision, only to be told to return the next day. (為這個(gè)決定我們幾乎等了三個(gè)小時(shí),可結(jié)果被告知第二天返回。)

  從考試角度看,狀語從句的重點(diǎn)是:時(shí)間、原因、條件、讓步和比較

  注:如前所述,本講座不是經(jīng)典語法書,有些講法從廣義上說是不完整的,甚至是不確切的,如:"逗號(hào)","不能連接兩個(gè)句子"的提法,但這些概念對(duì)于理解英語的某些語法現(xiàn)象,特別是解題是實(shí)用的。"相信我,沒錯(cuò)的".
