It was not yet eight oclock _ 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 B2.(典型例题 )That was really a splendid evening,Its 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 D3.(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 D4.(典型例题北) Its no wonder youve 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 C5.(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，Whenas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,lets 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.

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, youd 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 wont 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 wont 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 A2.(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 C3.(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 C4.(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 B5.(典型例题) I will come _ Mary is invited too.A. unless B. tillC. 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 + manyfewlittle/much + 名词 + that. 此处manyfewlittlemuch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 cant go to school.He is such a young boy that he cant go to school.He is so young a boy that he cant go to school.He made such rapid progress that he was praised by his mother.Soon there were so many deer that they ate up all the wild roses.考场思维训练1 China can get more benifit it is a member of WTO.A. because B. on condition that C. though D. when答案: B解析:on condition that 引导条件状语从句，意为“在前条件之下”。2 Tom is _ a young boy he cant earn money.A. such/that B. so/thatC. 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。3 He will not leave it is fine tomorrow.A. if B. unless C. as long as D. in case答案: B解析:这是一个真实条件句，unless意为“除非”，即“除非明天天气好转，否则他不会离开的。”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 B2. (经典题)We should finish the important job,_ .A. long it takes howeverB. it takes however longC. long however it takesD. 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 D3.(典型例题建)English and French are taught here.
