第五讲 状语从句.doc

1．在时间状语或条件状语从句中，通常用一般现在时代替一般将来时，用现在完成时代替将来完成时。

2．辨析：when，while，as引导时间状语从句。while必须与延续性动词连用，强调主句动作延续到从句所指的整个时间时，只能用while；表示“随着”只能用as；表示有规律的“每当”时或主句动作与从句动作有先后时，只能用when。 3．辨析：because，since，as引导原因状语从句。because语气最强，表示直接的原因，是说话人认为对方不知道的原因，它引导的从句通常位于主句之后；在回答why时，或者在强调结构中，只能用because。since和as是对大家已知的事实提供理由或背景，它们引导的从句多位于主句前，有时也位于主句后。 4．as引导让步状语从句时，从句中的状语、表语或动词必须置于句首；though引导让步状语从句时，这些成分可置于句首也可用正常语序；但although等其他词引导的让步状语从句不能将这些成分前置。

5．表示“虽然”的连词though/although不能与表示“但是”的连词but连用；表示“原因”的because等连词不可与表示结果的连词so等同时使用。

读语篇，悟语法。反复朗读下列短文，领悟画线黑体部分。思考：有多少种状语从句？下面的状语从句各属于哪一种？有哪些特殊的用法？

My mother was cooking in the kitchen while[1] I was doing my school assignments.As__soon__as[2] I finished my homework, I went to get some water to drink.Then the doorbell rang.However, my sister unlocked the door before[3] I could open it.We were surprised the__moment[4] we saw her because[5] her clothes and face were terribly dirty.She looked much poorer than[6] we expected.Since[7] we didn’t know what had happened to her, we stood there and waited for my sister’s story.We wouldn’t leave unless[8] my sister told us all about it.After[9] my sister got changed, she told us that she fell into a ditch when[10] she walked on a path on her way to my uncle’s home in the countryside.She couldn’t get out of the ditch.Although[11] she cried for help, no one could hear her.She tried to climb out of it, but, however[12] hard she tried, she failed to escape from it.As[13] time went by, she got worried.After several vain attempts she had to stand where[14] she was and waited until[15] a boy student passed by and gave her a hand.The boy reached her a long rope and told her to climb with the rope.She did as[16] the boy told, so__that[17] she came out.My sister also warned us to be careful when[18] walking on a path even__though/if [19] we are in a great hurry.That’s true.We should mind our step so__that[20] we can ensure our safety.

1.用于对比两件事，意思是“而……”用while，不能用when/as代替。 2．as soon as引导时间状语从句，表示“一……就……”。 3．before表示“还没来得及就……”。

4．名词词组如the moment/the second/the day/the first time/next time...等可以用来引导时间状语从句。

5．引导表示原因的从句时用because，其引导的原因状语从句一般放在主句之后，而如果只是名词性短语表示原因，则用because of引导。

6．在表示比较时，用than来引导比较状语从句，than也可以作介词。 7．对大家已知的事实提供理由或背景时，常用since引导，意思是“既然”。其

引导的从句多在主句之前。

8．引导条件状语从句，unless＝if...not，是“除非，如果不”之意。 9．after/before引导表示时间先后的状语从句，根据实际表达需要选用其一。 10．when引导表示“当……时”的时间状语从句。

11．引导让步状语从句时，可以用although或though，主句可以与副词still连用，但不能再与连词but连用了，一个复合句只需一个连词。当是as引导让步状语从句时，从句中的状语、表语或动词置于句首。

12．however引导让步状语从句时，其后常接形容词或副词，用于修饰该形容词或副词，wherever，whenever也可以引导让步状语从句，在从句中作状语，相当于no matter how/where/when；另外whatever，whoever，whichever也可以引导让步状语从句。

13．表示“随着”时，只能用as引导。

14．引导地点状语从句时，用where/wherever，表示“在……的地方”。 15．固定用法“直到……才……”可以用两种表达形式：“延续性动词＋until＋句子”(用肯定形式)；“not＋短暂性动词＋until＋句子”(用否定形式)。 16．引导方式状语从句时，可以用as，意思是“按照，像……那样”。 17．so that引导结果状语从句，从句表示的通常是某件事的结果。

18．when引导表示“当……时”的时间状语从句时，如果主句的主语和从句的主语是一致的，可以省略when从句的主语和be动词，用分词来表示。 19．表示“即使，尽管”的even though/if引导让步状语从句。

20．so that除了引导结果状语从句外，还可以引导目的状语从句，常与情态动词can/could等连用。
