(九) 复合句——状语从句
完整版英语语法状语从句的归纳总结

在复合句中修饰主句或主句中的某一成分的从句叫状语从句。
状语从句通常由从属连词或起连词作用的词组引导,有时甚至不需要连词直接和主句连接起来。
状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。
一、时间状语从句时间状语从句是表示时间关系的从句。
可以引导时间状语从句的连词很多,根据意义和主从句之间的时间关系,通常可分为以下几种情况:A.when, while, as, wheneverwhen, while, as表示主句谓语作和从句的谓语动作同时发生或几乎同时发生。
1.when①when表示点时间时,从句中用短暂性动词;表示段时间时,用持续性动词。
When I got home, my family were already having dinner.我到家的时候,全家已在吃晚饭。
(when表示点时间)When they were still talking and laughing, the teacher came in.当他们还在说笑的时候,老师进来了。
(when表示段时间)He waved a hello when he saw her.当他看见她的时候,就挥手打了个招呼。
(when表示点时间)When you think you know nothing, you begin to know something.当你认为自己一无所知的时候,就开始知道一些事情了。
(when表示段时间)注意:当when意思是正当……时候(and at that moment)时,when只能跟在前一分句之后。
He was about to go to bed when the doorbel rang. 他正要上床,忽然门铃响了。
They were watching the World Cup when suddenly the lights went out.他们正看着世界杯比赛,突然灯灭了。
复合句(状语从句、定语从句、名词性从句)

4. while从句的谓语动词不可以是短暂性的。
考点归纳2:时间、条件状语从句的时态一致性 1. 句型“It will be+段时间+before从句”,表示 “不久 …… 就 ……”。从句用一般现在时代替一般将来 时。
2. 句型“It is+段时间+since+一般过去时。”主 句常用现在完成时,从句常用一般过去时。若从句谓语 动词是延续性的,表示动作的终止;若从句谓语动词是 短暂性的,则表示动作的开始。
【解析】B 题意:2011年4月29日,威廉王子和凯特· 米德尔顿步入了他们的婚礼殿堂。先行词是表示时间 的名词,定语从句缺少状语,所以用 when 引导。 that 在从句中不能作状语; since 与 before 不能引导定语从 句。
例 2 : (2011· 江 西 卷 )Please call my secretary to arrange a meeting this afternoon, or ______ it is convenient to you. A. whenever C. whichever B. however D. wherever
【解析】D 他的字迹模糊不清,以至于很难弄清他 到底在试图表达什么。所选项引导 make out后的宾语 从句,并在从句中作表语,故用what。
【小结】
状语从句是近几年高考常考的内容之一。主要考 查时间状语从句,地点状语从句,原因状语从句,结 果状语从句,目的状语从句,条件状语从句和让步状 语从句。很少考查方式状语从句。
考点归纳2:关系代词与关系副词的选用 如果先行词是时间、地点或理由,而引导词在从 句中作时间、地点、原因等状语时,引导词用 when, where, why;有时尽管先行词是时间、地点或 理由,但是引导词在从句中不作状语,而是作主语、 宾语或表语,引导词则用that或which。

1、时间状语从句
2、until/ till 引导词: ① until和till意为“直到”,很多时候可以互换,但是用于句首的时候,常用until。 Until you get back, I will sit here.
3、让步状语从句
(表示主句中的某一动作或状态与从句中的某一动作或状态在意义上有部分矛盾。) 1、although/though 引导词: although/though意为“尽管,虽然”,不与but连用,但可用yet/ still. Although/ though he works hard, yet he makes slow porgress.
③ She is such a beautiful girl that everybody loves her.
4、结果状语从句

(4) for 也常引导表示原因的分句,但 for是并列连词,因此不能用于句首;for 提供的理由是一种补充性的说明,且 for 前常有逗号:
The days are short, for it is now December. 白天短了,因为已是12月了。 (四) 目的状语从句
引导目的状语从句的连词:in order that, so that(为了);for fear that, in case, lest(以免)等。

As he was reading(或read), he was listening(或listened) to the radio. 他边看书边听广播。

(九)复合句——状语从句(九) 复合句——状语从句说明: 所有相关复合句的综合练习将出现在“从句综合练习”章节❖ 考点归纳1. 状语从句的类型: 时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、方式状语从句2. 时间状语从句:⑴ 连接词及固定搭配: when, while, as, since, after, before, until / till, once, each time, everytime, any time, whenever, as soon as, the moment, the minute, the instant, hardly / scarcely / barely / rarely … when / before, no sooner … than, just as, directly, immediately, instantly, shortly after, soon after, it won ’t be long before, by the time, it ’s the first time that, it ’s … since, the first time, the last time⑵ as soon as 与hardly … when 等结构都能表示“一……就……”,但两者的时态不同;前者一般主从句均为一般时态,表示一般情形遵从主将从现原则;后者一般主句为过去完成时,从句为一般过去时,且在句首引起倒装⑶ 特殊地,可用the minute, each time, the first time 等名词或名词短语充当连接词引导时间状语从句,该类词称为边际从属连词 3. 地点状语从句可由where, wherever 引导,前者指特定地点,后者为无特定地点4. 原因状语从句:⑴ 可由because, since, now that, as, in that 引导,注意for, so, with + n . + 宾补结构⑵ 现代英语中,because 与for 都可引导原因状语从句,且都能表示“直接理由”与“间接理由”,如It must be very late, for the streets are quite deserted. (间接理由)上句中的for 实也可替换为because ,只是在两者同时存在时,使用for 语势较弱,更显出说话人的推断的不确定性,说明说话人的推断略显主观臆断⑶ 在表述直接理由时,because, since, as 从句位置既可在主句前,也可在句尾;而for 则只能位于主句后;此外,because 可回答why 问句,because 前可加入诸如simply 的修饰语,because 从句也可作为强调句的强调部分,这些场合下because 不能替换为for ;若because 也表述的是间接理由,则其位置只能在主句后 5. 条件状语从句的连接词及相关搭配: if, unless ( if … not), on condition that, given that, as / solong as, suppose that, even if, even though, provided that, in case, lest, given that, considering that, since, now that 等6. 目的状语从句可由that, in order that, so that, for the purpose that, in the hope that 等作连接词或固定搭配,常与情态动词连用7. 结果状语从句:⑴ 连接词及固定搭配: that, so … that, such … that, so that 等 ⑵ such 修饰名词,so 修饰形容词或副词,such / so 结构类似于what / how 的固定结构;当such 修饰可数名词单数时可将其与so 结构互换;若such 修饰不可数名词或可数名词复数时则无法互换⑶ 当many, few, little, much 表多少修饰名词时只能用so ;若little 不表多少,且修饰可数名词单数时只能用such 8. 让步状语从句:⑴ although, though, as, while, even if, even though, however, whatever, no matter 系列等 ⑵ though 引导的让步状语从句可以倒装(也可不倒装),作用相当于as (必须倒装),此时though不能与although 替换;though 与although 都不能与but 并存,却能与yet 并存;as 引导让步状语从句时,倒装形容词、副词及无冠词的名词;只存在even though ,而无 *even although ;though 也可作连接性状语,而although 不可,如He said he would come; he didn ’t, though .⑶ -ever 系列与no matter 系列的区别(见前) 9. 比较状语从句(见第一章,此略)10. 方式状语从句可由as, as if, as though 引导❖ 考前巩固I.
