Unit 5 China and the World
核心语法:状语从句
一、核心概念
1. 什么是状语从句?
状语:修饰动词、形容词、副词或整个句子的成分
状语从句:用句子充当状语成分,说明主句动作的时间、地点、原因、条件、目的、结果、方式、比较、让步等
特点:由从属连词引导,不能独立成句
2. 状语从句在句中的位置:
句首:通常用逗号与主句隔开
句中:放在主句主语之后
句末:通常不用逗号
二、九种状语从句类型
1. 时间状语从句
表示主句动作发生的时间
引导词 含义 例句
when 当...时 When I got home, it was raining.
while 在...期间 While I was reading, he was sleeping.
as 一边...一边 As he walked, he sang a song.
before 在...之前 I must finish my work before I go home.
after 在...之后 After he left, I felt lonely.
since 自从...以来 I have lived here since I was born.
until/till 直到... I waited until he came back.
as soon as 一...就 As soon as the bell rang, we left.
once 一旦... Once you begin, you must continue.
重点:
when既可表示"时间点"也可表示"时间段"
while强调两个动作同时进行
时间状语从句中用现在时表示将来时间
2. 地点状语从句
表示主句动作发生的地点
引导词 含义 例句
where 在...地方 Please sit where you like.
wherever 无论在哪里 Wherever you go, I'll follow you.
3. 原因状语从句
表示主句动作发生的原因
引导词 含义 例句
because 因为(语气最强) I was late because I missed the bus.
since 既然(已知原因) Since you're busy, I won't trouble you.
as 由于(较正式) As it is raining, we'll stay at home.
for 因为(补充说明) It must have rained, for the ground is wet.
辨析:
because回答why的提问
since和as多放句首
for是并列连词,多放句末
4. 目的状语从句
表示主句动作的目的
引导词 含义 例句
so that 为了,以便 He got up early so that he could catch the train.
in order that 为了(更正式) Study hard in order that you can pass the exam.
lest 以免,唯恐 He spoke quietly lest he should be heard.
注意:
so that从句常用情态动词can/could, may/might, will/would等
5. 结果状语从句
表示主句动作的结果
引导词 含义 例句
so...that 如此...以致 He ran so fast that I couldn't catch up.
such...that 如此...以致 It was such a hot day that we stayed indoors.
so that 结果 He studied hard, so that he passed the exam.
辨析:
so + 形容词/副词 + that
such + (a/an) + 形容词 + 名词 + that
6. 条件状语从句
表示主句动作发生的条件
引导词 含义 例句
if 如果 If it rains, we'll stay at home.
unless 除非 You won't succeed unless you work hard.
as/so long as 只要 You can borrow it as long as you return it.
on condition that 条件是 I'll help you on condition that you try.
重点:
if从句中用现在时表示将来时间(主将从现)
unless = if not,本身含否定意义
7. 让步状语从句
表示尽管有某种情况,主句动作仍发生
引导词 含义 例句
although/though 虽然 Although it was raining, we went out.
even if/even though 即使 Even if I fail, I'll try again.
no matter + 疑问词 无论 No matter what happens, I'll support you.
whatever/whoever等 无论什么/谁 Whatever you say, I won't believe you.
注意:
although/though不能与but连用
no matter what = whatever
8. 比较状语从句

引导词 含义 例句

四、状语从句的省略
省略条件:
当状语从句的主语和主句主语一致,且从句谓语含有be动词时,可省略主语和be动词
完整句 省略句

37.C
【解析】句意:明天你想去爬鼓山吗?——如果我的母亲允许,我就和你一起去。不定式做宾语表示具体的将要进行的动作,结合语境可知上文用不定式做宾语。当主句描述将来动作时,英语条件状语从句中用一般现在时态表示将来动作,结合语境可知选C。
【点评】不定式作句子成分表示具体的将要进行的动作,一般不用于介词后面。动名词作句子成分往往表示抽象的,反复发生的动作。介词后面一般接动名词作宾语,也有部分动词后接动名词做宾语,注意和不定式作宾语表达含义的不同。英语状语从句的时态与主句有比较紧密的联系,若主句为一般将来时,时间和条件状语从句通常要用一般现在时表示将来,而不能直接使用将来时态。

40.C
【解析】句意:——你觉得罗伯特明天会去动物园吗?——如果他没有太多功课,我想他会去的。if引导的条件状语从句,主句是将来时,那么条件状语从句用一般现在时表将来,即主将从现。根据he will go,一般将来时,可知从句用一般现在时,主语是he,谓语动词是行为动词,否定句借助于助动词doesn't,故选C。
【点评】此题考查一般现在时的否定结构,注意助动词的使用。
41.A
【解析】句意:如果明天不下雨,我们就去野餐。A.将有,一般将来时;B.有,一般过去时;C.已经有,过去完成时;D.正在有,过去进行时。if引导的条件状语从句,从句用一般现在时,主句用will+动词原形,句子是主句,所以用will have,故选A。

43.D
【解析】句意:自从中国加入世贸组织,巨大的变化已经发生了。enter进入,及物动词,后面不加介词into,排除A、B。C.已经进入,现在完成时;D.进入,一般过去时。since引导的时间状语从句,从句用一般过去时,主句用现在完成时,since所在的句子是从句,所以用一般过去时,故选D。
【点评】考查since引导的时间状语从句,注意平时识记ince引导的时间状语从句,从句用一般过去时,主句用现在完成时和enter是及物动词。
44.D
【解析】句意:当Amy打电话时,我正在我的书房里读书。read动词原形,读;will read一般将来时;am reading现在进行时;was reading过去进行时。根据"when Amy called."可知,强调发生某事的时候,另一件事情正在发生,要用过去进行时。故选D。
【点评】考查过去进行时。掌握when引导的时间状语从句,结合语境,选择正确答案。
45.C
【解析】句意:无论你做什么,安全都是最重要的。A:What通常引导名词性从句(如主语从句、宾语从句);B:How表示方式或程度(如"如何");C:No matter what表示"无论什么",引导让步状语从句;D:No matter where表示地点("无论哪里")。No matter what 可引导让步状语从句,且 what 在从句中作 do 的宾语,故选C。
【点评】考查状语从句,本题涉及no matter what引导的让步状语从句。
46.C
47.A

【点评】考查连词辨析。注意since既可以引导时间状语从句,也可以引导原因状语从句。
49.A
【解析】句意:如果有人闯红灯,那真的是很危险的。if如果,unless除非,though虽然,until直到,根据前文"那真的是很危险的"和后文"有人闯红灯",可知此处应该是if引导的条件状语从句。故选:A。
【点评】考查状语从句的引导词,同学们需要根据前后语境选择合适的引导词。
50.B
【解析】句意:——你知道汤姆什么时候到这吗?——对不起,我不知道。当他到的时候,我会尽快打电话给你。根据When he ________, I'll call you as soon as possible。可知Tom还没有来,所以第一个空填will arrive。还可以看出这是一个时间状语从句,要遵守主将从现的原则,所以第二空填arrives。故选B。
【点评】考查宾语从句和状语从句。注意区分复合句的主句和从句。
