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:用一个完整的句子充当状语,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. 状语从句的位置:
句首:从句在前,主句在后,用逗号隔开
句中:主句主语在前,从句在后,常不用逗号
句末:主句在前,从句在后,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 注意要点
when 当...时 When I got home, it was raining. 既可表示"时间点"也可表示"时间段"
while 在...期间 While I was reading, he was sleeping. 强调两个动作同时进行
as 一边...一边 As he walked, he sang a song. 强调伴随或同时发生
before 在...之前 I must finish my work before I go home. 主将从现:主句用将来时,从句用现在时
after 在...之后 After he left, I felt lonely. 时间先后关系明确
since 自从...以来 I have lived here since I was born. 主句常用现在完成时
until/till 直到... I waited until he came back. not...until表示"直到...才"
as soon as 一...就 As soon as the bell rang, we left. 强调动作的紧接性

wherever 无论在哪里 Wherever you go, I'll follow you.
3. 原因状语从句

because 因为(语气最强) I was late because I missed the bus. 回答why提问,不与so连用
since 既然(已知原因) Since you're busy, I won't trouble you. 多放句首,表示已知原因
as 由于(较正式) As it is raining, we'll stay at home. 多放句首,语气较弱
for 因为(补充说明) It must have rained, for the ground is wet. 是并列连词,放句末

表示主句动作发生的条件
引导词 含义 例句 时态要点
if 如果 If it rains, we'll stay at home. 主将从现:从句现在时,主句将来时

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 注意要点

参考答案及试题解析
1.C
【解析】这题考查让步状语从句的用法:wherever="no" matter where,“无论在哪”,句意是:无论这个电影明星到哪里,都有很多粉丝等着她。选C。
2.B
【解析】句意: 只要你少吃肉多吃蔬菜,你就会比以前更健康。as long as引导条件状语从句,时态是主将从现,故此处是一般现在时,故选B。
【点评】考查时态,注意as long as引导条件状语从句,时态是主将从现的用法。
3.C
【解析】句意:——我们的微信账号是安全的吗?——是的,没人能使用它,除非他们有密码。A. if 如果,是否;B. when 什么时候;C. unless 除非,如果不;D. since 自从。根据句意,不缺主谓宾,这道题使用翻译法较合适,把四个选项代入句子中理解即可得出答案,最符合文意的是unless。故选C。
【点评】考查条件状语从句的引导词。初中阶段考查的从句引导词较简单,一般选择代入法和翻译法即可得出答案,但也要注意要学会分析句子的主谓宾。本题中不缺少主谓宾,而是作为有前提条件的状语,所以是unless引导的条件状语从句。
4.D
【解析】句意:这位记者说得如此的快,以至于没有一个人听清楚她说了什么。分析:考查固定句型:"so…that"有"如此程度,以至于……"而 "too…to"则有"如此程度以致不能……"的意思。故此在 "too…to"后不须再有否定字眼,若不,就有双重否定的情况出现。联系句意:如此……以至于……故选D
【点评】考查固定短语的用法。
5.A
【解析】句意:别担心!我们经理一回来我就会联系你。A:comes 是动词come的一般现在时第三人称单数形式,用于描述习惯性、经常性或现在发生的动作。B:came 是动词come的过去式,用于描述过去发生的动作。C:has come 是动词come的现在完成时形式,用于描述从过去某一时间点开始到现在为止已经完成的动作。D:will come 是动词come的将来时形式,直接表示将来要发生的动作。因为这是一个as soon as引导的时间状语从句,从句中通常使用一般现在时来表示将来的动作。所以,A选项comes是正确的选择。故选A。
【点评】考查时间状语从句中的时态用法,特别是as soon as引导的从句中,当主句为将来时,从句应使用一般现在时来表示将来的动作。
6.B
【解析】句意:当我的爸爸到家时,我正在做作业。when引导的时间状语从句中,动词可以是非延续性动词,也可以是延续性动词,做作业,do homework,是延续性动词,用过去进行时,was doing,故选B。
【点评】考查过去进行时,注意从句中的时间状态。
7.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。
8.B
【解析】句意:我们想在毕业后开始工作,这样我们就不会依赖父母了。考查连词(短语)辨析。as soon as一……就……,表时间;so that以便,表目的;even though尽管,表让步;since由于,表原因。根据下文“we won't depend on our parents我们不会依赖父母”可知毕业后开始工作的目的是不依赖父母,故选B。

9.D
【解析】句意: 旧剧院很快就要关闭了,除非一些额外的捐款已经到位。A所以,B如果,C因为,D除非,根据The old theatre will close soon旧剧院很快就要关闭,和some extra donations are made,一些额外的捐款已经到位是假设,表示意外的用unless,故选D。
【点评】考查连词,注意unless的用法。
10.A
【解析】句意:——你觉得电影《功夫熊猫3》怎么样 ——它是如此令人兴奋以至于我想再看一遍。根据 题干可知该题考查so……that与such……that的用法区别;so与such的后面都可以跟that从句;但so的后面跟形容词或副词, so+ adj./adv.+that从句;such的后面跟名词;such+名词+that从句;根据句中的exciting是形容词, 可知该空应填so……that。故选A。
【点评】状语从句。

12.A
【解析】句意:陈家鹏在400米接力赛中一直跑到终点。till直到;since自从;before在……之前;when当……时候。根据 Chen Jiapeng kept running陈家鹏一直跑,可知应是一直跑直到终点,应用连词till"直到"。故选A。
【点评】考查连词辨析。注意首先查看选项四个连词意思,根据前后逻辑选择合适的连词。
13.D
【解析】句意:当我正在遛狗时,意外发生了。when引导的时间状语从句,两个动作同时发生,事故发生,happen,非延续性动词,因此用一般过去时,happened,故选D。

【点评】考查连词辨析。注意:1. 分析句子结构。首先,明确空缺处前后是分句、短语还是单词,判断是否需要连词(如并列连词and/or/but)或从属连词(because/although/when)。若连接两个独立分句,需确认是并列关系(用逗号+并列连词)还是主从关系(用从属连词)。2. 识别逻辑关系。根据上下文判断逻辑类型:因果关系(therefore、because/since/as),转折关系(but/yet,although/even though),条件关系(unless(=if not), provided that),时间关系(while, as soon as)3. 排除干扰项。以词性、逻辑关系以及固定搭配为根据一一排除错误选项。4. 验证答案。将所选连词代入,检查是否通顺。5.注意高频易错点。如,while可能表时间("当…时")或对比("尽管");as可表原因("由于")或时间("随着"),需结合语境;since时间状语从句用一般过去时,原因状语从句常用现在完成时。
15.D
【解析】句意:他们必须早起以便能赶上早班车。A:as soon as一......就......; B:because因为; C:if如果; D:so that以便。根据前后句的意思,可知后句是前句发生的目的,要用连词so that。故选D。
【点评】考查连词辨析。理解连词的词义和用法,根据前后句的关系,选择正确的连词。
16.B
【解析】句意:我爷爷经常告诉我,我们必须在年轻的时候努力工作以获取更多的知识。A.after及词义:在……之后;B.while及词义:当……时候;C.before及词义:在……之前;D.until及词义:直到。根据"we must work hard to get more knowledge ____ we are young"可知,此处表达的是在年轻的时候要努力获取知识,强调两个动作同时进行,用while表示"当……时候"符合语境,故答案为:B。
【点评】考查连词辨析。注意各个连词所表达的时间关系以及在语境中的运用,要根据句子的具体含义和逻辑关系来选择合适的连词。
17.C
18.B
【解析】句意:我不知道如何找到他们因为他们没告诉我他们住在哪个房间。状语从句,疑问词后句子半倒装。故选B。
【点评】本题考查状语从句,疑问词后句子半倒装。
19.C
【解析】句意:毫无疑问,如果学生得到老师更多的表扬,他们的学习就会取得进步。make progress取得进步,固定搭配,一般将来时是will make progress;get得到,实义动词,一般将来时是will get。if引导的条件状语从句从句用一般现在时,主句用一般将来时,结构是will+动词原形,if所在句子是一般现在时,主语是复数they,所以get用原形;主句用will make progress,故选C。
【点评】考查if引导的条件状语从句,首先识记选项区别,然后识记if引导的条件状语从句从句用一般现在时,主句用一般将来时,结构是will+动词原形,理解句意。
20.C
【解析】unless除非,如果不;whether是否;although 虽然,尽管;until直到。句意:每天我母亲都努力挤出时间来和我聊天,尽管她在一整天的工作之后非常累。——你有这样一位伟大的母亲,太幸运了。结合语境可知选C。
【点评】连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词。连词的用法都比较多,语义之间还有交叉,熟记其基本应用规则,了解其区别,注意固定搭配对象,是做好此类题型的关键。
21.A
【解析】 句意:我的英语老师总是告诉我,只要你每天都大声朗读英语,你的英语口语就会变得更好。 as long as 只要, 引导条件状语从句 ; whether 是否 , 引导名词性从句或让步状语从句 ; even though 即使, 引导让步状语从句 。根据句子语境分析可知,此处表示"只要你每天都大声朗读英语,你的英语口语就会变得更好。", 表示只要某个条件存在,结果就会发生 ,故选A。
