1、高考英语语法总复习:原因和结果状语从句讲解<原因状语从句>原因状语从句是指在复合句中表示主句动作发生原因的句子。原因状语从句可置于句首,也可置于句尾。引导词有because, since,as,now(that)等。1.because引导的原因状语从句because引导的原因状语从句往往比主句显得更重要。表示动作发生的直接原因,表因果关系的语气最强,用来回答why引导的疑问句,所引出的原因往往是听话人所不知道或最感兴趣的。如:Why didn't you go with us today?你为什么今天没跟我们一起去?一 Because I was too tired.因为我
2、大累了。He is leaving because he is fed up with the boss.他离开是因为他厌烦老板。I did not go to school yesterday because I was ill.我昨天没去上学,因为我生病了。Because it was raining,I had to stay at home.因为下雨,我只好待在家里。汉语里我们习惯说“因为所以”,但使用英语时不能将 because与so连用。表示因果关系时只能二选一。如:Because my bike was broken,so I went to school by bus yest
3、erday. (误)I went to school by bus yesterday because my bike was broken. (正)My bike was broken,so I went to school by bus yesterday. (正)因为我的自行车坏了,所以我昨天坐公共汽车上学。Because my mother was ill, so I didn't go to your party(误)I didn't go to your party because my mother was ill. (正)My mother was ill, s
4、o I didn't go to your party. (正)因为我妈妈病了,所以我没去参加你的聚会。2. since 的用法since意思是“既然,由于,因为”,表示已知的、显然的理由,较正式,多位于句首。since引导的从句是次要的,重点强调主句的内容。Since tomorrow is LI Hong's birthday, lets give him party.既然明天是李宏的生日,咱们给他开一个派对吧。Since everyone is here, lets start our class.既然大家都来了,咱们就开始上课吧。since you are free,
5、you'd better tidy your bedroom.既然你有空,你最好把卧室整理一下。Since it is late, I shall go home right now.(由于)时间不早了,我得马上回家。3.as的用法as与since用法差不多,所引出的理由在说话人看来已经很明显,或已为听话人所熟悉而不需用 because加以强调。as引导的从句与主句同等重要。As you were not there, I left a message.因为你不在那里,所以我留了个信儿。because,since和as的用法区别:和 because相比, since和as的语气稍弱。1
6、)because语气最强,用来回答why引起的提问,可表示已知或未知的事实。它可和强调词only,merely,just及否定词not连用,所引导的从句常位于主句之后,只有强调时才置于主句之前。它还可用于强调结构。I did not go to school yesterday because I was ill.我昨天没去上学,因为我生病了。It was because I wanted to see my uncle that I wen to town yesterday.因为想去看叔叔我昨天才进城的。He was punished only because he broke the l
