状语从句与宾语从句考点归纳2009-08-19 来源： 网络 字号：大 中 小热点一对引导词的考查引导状语从句的连接词1. 引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/ until, as soon as等。如：When I got home, he was having supper.2. 引导原因状语从句的连词有because, since, as, for等。如：I missed the train because I got up late.3. 引导结果状语从句的连词主要有so/ such.that., so that等。如：She is so short that she cant reach the buttons of the lift.4. 引导让步状语从句的连接词有though, although, even if, even though, however/ no matter how, whatever/ no matter what等。如：Although its raining, they are still working in the field.5. 引导条件状语从句的连接词有if, unless, as long as等。如：You wont pass the exam unless you work hard on it.引导宾语从句的连接词一般来说，宾语从句的引导词是根据从句的原句句式而定：原句是陈述句时，用引导词that;原句是一般疑问句时，引导词用if或whether;原句是特殊疑问句时，引导词用原疑问词。如：I am glad(that)youve passed the exam.I dont know if/ whether it will rain tomorrow.I wonder where he got so much money.热点二对主、从句时态呼应的考查状语从句的时态以when, as soon as, before, after, until等引导的时间状语从句和if引导的条件状语从句，当主句用一般将来时，从句要用一般将在时表示将来。如：Ill tell you as soon as he comes back tomorrow.宾语从句的时态1. 宾语从句的时态要和主句时态相呼应。当主句谓语动词是过去时态时，宾语从句也要用相应的过去时态(即一般过去时、过去进行时、过去将来时或过去完成时)。如：Li Lei told me that he was getting ready for the exam these days.2. 若主句是现在时或将来时，宾语从句可根据情况选用恰当的时态。如：The radio reports that its going to rain this afternoon.3. 若从句表示自然现象或客观真理时，其时态常用一般现在时，而不受主句限制。如：Yesterday Tom said that the earth goes round the sun.热点三对复合句简化的考查含有状语从句的复合句转化为简单句so.that.引导的结果状语从句有两种情况：1)表示肯定的结果，可与“enough to”结构互换;2)表示否定的结果，它既可以与“too.to”结构互换，也可以改为“not + adj./ adv. + enough to”。如：The room is so large that it can hold 1,000 people. The room is large enough to hold 1,000 people.含有宾语从句的复合句转化为简单句1. 主句谓语动词为hope, wish, agree, decide, choose等，其后带(that)宾语从句，若主从句主语一致时，从句可以简化成不定式结构。如：He decides that he will visit our school.He decides to visit our school.2. 主句的谓语动词为感官动词see, hear, watch或find等时，宾语从句常简化成“感官动词find+宾语+宾语补足语”结构，此时宾语由从句的主语转化而来，而宾语补足语多为不带to的不定式或V-ing形式。如：I saw that some children were playing in the park.I saw some children playing in the park.3. 由特殊疑问词引导的宾语从句，当主从句主语一致时，宾语从句可简化成“疑问词+不定式”结构。如：I dont know how I can get there. I dont know how to get there.热点四对两类从句综合起来考查1. 从引导词看，if充当宾语从句的连接词时，相当于whether，意为“是否”;充当从属连词，引导条件状语从句时，意为“如果”。when充当宾语从句的连接词时，意为“什么时候”;充当从属连词，引导时间状语从句时，意为“当的时候”。2. 从时态看，if和w
