新一轮中考复习备考周期正式开始, 从结构上说,英语连词分两大类:并列连词和从属连词。并列连词连接两个或两个以上地位平等的字、词组或分句。而从属连词,连接两个或两个以上的分句,以此来形成复杂句中的从属分句。其引导的句子与主句的地位不平等,处在从属的地位,因此称之为从属连词。 从属连词主要用来引导名词性从句和状语从句。名词性从句主要有:主语从句、宾语从句、表语从句和同位语从句;而状语从句主要有时间、条件、目的、结果、原因、让步、方式、地点和比较状语从句。各种从句的连词主要如下表所示: 以上连词的用法主要如下: 1.名词性从句: (1)that,if和whether:that表示肯定、确定之意;if和whether译为“是否”,含有否定、不确定之意。 Whether he will come here is still unknown to us.我们还不知道他来不来。 I doubt(whether)if the answer is right.我怀疑这答案是否正确。 I don’t doubt that the answer is right.我不怀疑这答案是正确的。 (2)if和whether:引导宾语从句时,两者可互换;引导主语、同位语和表语从句时,只能用whether,不能用if。 宾从:He wanted to know whether(if)they could help him.他想知道他们能否帮他。 主从:Whether you will come or not doesn’t matter.你来不来都无所谓。 同从:They are discussing about the question whether it will rain tomorrow.他们在讨论明天会不会下雨这个问题。 表从:The question is whether he will come here.问题是他会不会来。 2.状语从句: (1)时间:We were about to leave when it began to rain.就在我们要离开时,天开始下雨。 (2)地点:Where there is a will,there is a way.有志者,事竟成。 (3)条件:If it rains tomorrow,we will not go out.明天若是下雨,我们就不出门了。 (4)目的:He read aloud in order to make everybody hear him.为了让所有人都听见,他大声地朗读。 (5)结果:He was so careless that he made many mistakes in his work.他太粗心了,以致于工作中出现了很多错误。 (6)原因:Because it is going to rain,the meeting is put off.由于天要下雨,所以会议取消了。 (7)让步:Although he was young,he knew a lot.尽管他年轻,他知道很多东西。 (8)方式:He behaves as if he were a child.他的举止就像个孩子。 (9)比较:He runs more quickly than his sister does.他比他妹妹跑得快。 (责任编辑:admin) |
