命题角度 1 时间状语从句和原因状语从句的运用
1.(典型例题)—Did Jack come back early last night?
—Yes. It was not yet eight o’clock __ he arrived home.
A. before B. when C. that D. until
[考场错解] C
[专家把脉] 本题很多考生都以为是强调句，选that.事实上本题是一个when引导的时间状语从句，句意为“他回家的时候不是八点钟”。
[对症下药] B
2.(典型例题 )That was really a splendid evening,It’s years I enjoyed myself so much.
A. when B. that C. before D. since
[考场错解] A
[专家把脉] 很多考生都选A，认为是由when引导的一个时间状态语从句。本句是状语从句，但并不能用 when引导，而应该用since引导，此时since译为“从……起”，整句应该理解为“我多年未这么快乐过了”。
[对症下药] D
3.(典型例题苏)__ they heard the shout for help, they rushed out.
A. Immediately B. The moment C. The while D. All the above
[考场错解] A或B
[专家把脉] 考生往往对the moment可以用来引导时间状语从句较熟悉，而忽略其他。事实上，immediately和while也可引导时间状语从句，此时immediately = as soon as.
[对症下药] D
4.(典型例题北) It’s no wonder you’ve got a headache __ you drank so much last night.
A. though B. in case C. when D. while
[考场错解] D
[专家把脉] 很多考生都选D项，把while理解成“然而”或“当……时候”，仔细分析本句就会发现空格处应填一个能引导原因状语的词，此时只有when合适，其意义相当于since，seeing that或consldering that.
[对症下药] C
5.(典型例题京) He did not get up __ his mother came in.
A. till B. until C. not until D. before
[考场错解] B
[专家把脉] till(until)表示“一直到……”时，主句和从句都用肯定式；表示“直到……才”时，主句用否定式，从句用肯定式。
[对症下药] A
专家会诊
1.时间状语从句的引导词有:when，while，as， every time，the moment，hardly...when，no sooner...than等。
2.使用时间状语从句时要注意下列几个词:
as，while，When
as强调两个动作同时进行，动作通常是延续性的，且表示“一边……一边”；还可表示“随着时叵的推移”。例:
He always sings as he walks.
As time went on,his theory proved to be correct.
when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，有时还表示“就在那时”。例:
When the teacher came in, the students were reading aloud.
When he stayed in America, he learned a lot of English.
We were about to set out when it began to rain.
while在……期间，引导的从句的动作是延续性的，并侧重主从句的动作同时发生；有时while还表示转折关系“而”。例:
While his mother was cooking in the kitchen, the little boy fell asleep in the chair.
He is a worker,while his sister is a doctor.
原因状语从句的引导词有:as because,since,now that 等。
如:Now that you are all here,let’s reach a decision.
注意，for是并列连词，引导的是并列句，对前述内容作补充性说明。
考场思维训练
1 He always sings __ he walks.
A. when B. while C. as D. and
答案: C
解析:as强调动作同时进行。
2 __ the teacher came in, the students were fighting with each other.
A. While B. When C. As D. Since
答案: B
解析:when在本句中意为“当……时候”。
3 __ many boys were playing basketball on the playground, the gins were singing and dancing in the room.
A. When B. While C. Before D. As
答案: B
解析:while在本句中指主从句的动作几乎同时发生。
4 __ he walked along the street, he sang happily.
A. When B. While C. As D. That
答案: C
解析:when，while和as都表示“当…时候”讲，但when引导的从句的动作可同时发生，也可先后发生。 用as和while时则表示动作同时发生。
5 __ a lot of people make mistakes in life, you’d better give him a chance.
A. Because B. Since C. As D. Because of
答案: B
解析:because表明直接或明确的原因。since和as 引导的从句强调的是结果，不是原因。另外，since在语气上比as要强。
命题角度 2 条件状语从句和结果状语从句的正确运用
1.(典型例题) It is known to all that __ you exercise regularly, you won’t keep good health.
A. unless B. whenever C. although D. if
[考场错解] B
[专家把脉] 很多考生认为本题应该用whenever来引导时间状语从句，事实上分析本句结构和句意可知，it实际上是替代后面从句的，句子的真正结构为:_ you exercise regularly，you won’t keep good health。因此，应该用unless，句意为“除非你经常有规则地锻炼，否则不会有好身体的”。
[对症下药] A
2.(典型例题)—Shall Brown come and play computer games?
—No,__ he has finished his homework.
A. when B. if C. unless D. once
[考场错解] A或B
[专家把脉] 本题若选A、B没有完全领会本题含义。在答语中实际上是一个省略句，引出一个条件“除非他先完成作业，否则不会来的”。
[对症下药] C
3.(典型例题)The scientists made __ rapid progress __ they were praised by their leader.
A. so... that B./,that C. such... that D. much... that
[考场错解] A
[专家把脉] so...that和such...that均可引导结果状语从句，但so后一般接形容词，构成so + adj/ adv + that结构，而such后接由形容词所修饰的名词，构成such + adj + 可数名词复数或不可数名词 + that结构。
[对症下药] C
4.(典型例题京) They worked hard __ they finished their work ahead of time.
A. so B. so that C. such that D. so as to
[考场错解] D
[专家把脉] 考生忽略了so as to后应接动词或动词短语，此句句意为“他们拼命干活，结果提前完成了工作”，应该用so that来引导结果状语从句，作“结果…”讲。
[对症下药] B
5.(典型例题) I will come __ Mary is invited too.
A. unless B. till
C. when D. on condition that
[考场错解] A
[专家把脉] unless意为“除非”，本句句意明显，即’若Marg来的话，我也来”，故用on condltlon that引导。
[对症下药] D
专家会诊
1.条件状语从句的引导词有:if，unless，as long as，so long as，on condtion that等。
2.结果状语从句的引导词有:so...that，such...that应该正确使用so和such
(1)so + adj.／adv.／分词 + that...
(2)so + adj + a + 可数名词单数 + that...
(3)so + many／few／little/much + 名词 + that... 此处many／few／little／much是表示数量的形容词。
(4)such + a + adj. + 单数可数名词 + that...
(5)such + adj.+ 可数名词复数或不可数名词 + that...例:
The boy is so young that he can’t go to school.
He is such a young boy that he can’t go to school.
He is so young a boy that he can’t go to school.
He made such rapid progress that he was praised by his mother.

考场思维训练
1 China can get more benifit it is a member of WTO.

C. 不填/that D. such/when
答案: A
解析:构成such + a + adj + 可数名词单数+that… 结构。

4 If it __ not raining now, I would not be staying at home.
A. is B. was C. will D. were
答案: D
解析:这是一个非真实条件句，即与现在事实相反，此时应用虚拟语气，be动词一律用were.
命题角度 3 让步状语从句和方式状语从句的运用
1.( 典型例题) Allow children the space to voice their opinions, they are different from your own.
A. until B. even if C. unless D. as though
[考场错解] D
[专家把脉] as though = as if，用在本句中明显不合语境，本句意为“请给孩子们发言的机会，即使他们的意见和你们的不统一”。even if 意为“即使”，符合语境。
[对症下药] B
2. (经典题)We should finish the important job,_ .
A. long it takes however
B. it takes however long
C. long however it takes
D. however long it takes
[考场错解] C
[专家把脉] 当however引导让步状语从句时，however可以用no matter how的替换，因此how ever后要接形容词，此外，however还应置于从句句首。
[对症下药] D
3.(典型例题建)English and French are taught here. You can choose __ you like.
A. no matter which B. whichever C. which D. whatever
[考场错解] A
[专家把脉] 在让步状语从句中，“no matter + 疑问词”结构和“疑问词 + ever”结构可互换，若选A，则B也可。本题实际上是一个名词性从句，whichever既引导宾语从句，又做like的宾语。
[对症下药] B
4.(典型例题) __ he is, he will be thinking of you.
A. Wherever B. Where C. Now that D. As soon as
[考场错解) B
[专家把脉] Where不能置于句首构成独立的分句。 wherever用来引导让步状语从句，相当于no matter where。
[对症下药] A
5.(典型例题) it rained heavily, they still went out.
A. If B. Unless C. Although D. Before
[考场错解] B
[专家把脉] unless意为“除非……”；A、D两项明显不合句意；although用在此句中用来引导让步状语从句，意为“尽管……”
[对症下药] C
专家会诊
1.让步状语从句的引导词有:though，although， as，even if，even though，疑问词 + ever，no matter + 疑问词，方式状语从句的引导词有：as，as if，as though。
2.由“no matter+疑问词”和“疑问词+ever”引 导的让步状语从句可互换。例:
No matter what happened, he wouldn’t mind.
= Whatever happened, he wouldn’t mind.
注意:“on matter+疑问词”结构只能引导让步状语从句，而“疑问词+ever”还可以引导名词性从句。例:
Whoever comes will be welcomed.
考场思维训练

命题角度 4 比较状语从句和目的状语从句的运用
1.(典型例题) As far as I am concerned, education is about learning and the more you learn, .
A. the more for life are you equipped
B. the more epuipped for life you are
C. the more life you are equipped for
D. you are equipped the more for life
[考场错解] C
[专家把脉] 本句实际上是"the more．．．the more.结构，第二个比较级修饰形容词equipped.
[对症下药]B
2.(典型例题)John shut everybody out of the kkitchen __ he could prepare his grand surprise for the party.
A. which B. when C. so that D. as if
[考场错解] D
[专家把脉] as if意思是“好像”，用来引导方式状语从句。分析本句不难看出，本句句意为“John的目的是能够为使参加聚会的人大吃一惊作准备”，因此应该用 so that引导目的状语从句。
[对症下药] C
3.(经典题)The population of China is larger that of India.
A. as B. than C. more than D. much as
[考场错解] C
[专家把脉] more than意为“超过”，在本句中，larger为比较级结构，本句意为“中国人口比印度人口多”，故应该用than引导比较状语从句。
[对症下药] B
4.(经典题)We must hurry up __ catch up with the last train.
A. that B. so that to C. in order that D. in order to
[考场错解] C
[专家把脉] 考生认为应该用in order that来引导目的状语从句，值得注意的是，in order that引导目的状语从勾时，真后接从句。本句中catch up with为动词短语，故不能选C项。
[对症下药] C
5.(典型例题东) we can do for you, we will be.
A. The more; the happier B. More; happier
C. The more; happier D. The more; happy
[考场错解] C

目的状语从句的引导词有：so that，in order that.
