初中英语语法:连接词辨析
对于连接词辨析知识的讲解内容,同学们好好学习吧。
(1) because、as、since、for 的用法:because(因为)表示原
因的语气最强,常表示必然的因果关系,从句一般 a fine day next Sunday is still a question. (下个星期天是不是
个好天还是个问题)(引导主语从句)/ Please ask him whether to go there with a raincoat or not. (请问一下带不带雨衣去那
儿)(作动词的宾语)/ Hainan is the place to be, whether
it ' s summer or winter. (海南是个该去的地方无论冬夏)(引导
让步状语从句)/ Please let me know whether you need my help.
(请告诉我你是否需要我的帮助)(引导宾语从句)(如果换成if那 么还可能表示“如果你需要我的帮助请告知”)
(3) while、when as的用法区别:while常表示一个较长的动
作,它引导的从句动作与主句的动作是同时发生的、是平行的; when
可以表示较短的动作也可以表示较长的动作,主句和从句的'动作可 以同时发生也可以先后发生;as与上两词同义,可替换while和 when,表示主句和从句的动作同时发生,常译为“一边 一
边 ”。如: Please do not trouble me while I am writing
my homework.(我写作业时请不要打搅我)/ I ll go home when
I have finished my job. (我干完了活儿就回去) / They were
running quickly across the road when they heard the sound of a truck ing. (他们正快速地穿过马路突然听到了卡车开来的声
音)/ As we walked in the dark street, we sang songs and talked loudly. (当我们在黑洞洞的街上走路时我们高声地唱歌说
话)
(4) till/until 与not • till/until 的区别:前者表示一个延
续性的动作,后者表示一个才开始的动作。如:I will stay here
and watch the baby until you return. (我会呆在这里看着娃娃
直到你回来)(stay这个动作一直进行到你return) / They won t go on working until they get what they think is reasonable.
(他们要到获得了他们认为合理的东西时才会继续干下去的)
另外till与until根本可以互换,但是在句首时只能用until, 不能用 till. 如:Until the last minute of the match we kept playing.(我们坚持到比赛的最后一分钟)/ Not until he had finished his work di
