中考英语状语从句考点归纳与例析

中考英语状语从句考点归纳与例析 【重点讲解】 中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的 “引导词”及其相关意义。 考点一：引导状语从句的连词的选择。 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。其中when，while和as都可表示"当……时候"，但用法有区别: when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。例如: When I got home, he was having supper. as意为"边……边……"或"与……同时",重在表示两个动作同时发生。伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如: They sang as they danced. while只可表示"段时间",从句谓语只限于延续性动词。例如: While I was sleeping, my father came in. 注意：从句谓语是持续性动词时,when，while和as可以互换。主、从句谓语都是终止性动词时，when与as可互换。从句谓语表示状态时，通常用while。 2、引导地点状语从句的常用连词是where。例如： Where there is a will there ia a way. 3、引导原因状语从句的连接词主要有because, as, since, for。例如： Tom was late for school this morning because he didn’t catch the early bus. As he was not well,I decided to go there without him. Since this method doesn't work, let's try another. for表示所说的理由是一种补充说明，因此, for引导的从句一般不放在句子的开头。例如: I decided to stop and have lunch, for I was feeling quite hungry. 注意：because语气最强，as, since, for次之。对于以why开头的问句，一般要用because引导的从句来回答。 4、引导条件状语从句的连接词主要有if, unless, as long as。例如： If I am not busy tomorrow, I will play football with you. Unless you tried it, you can’t imagine how pleasant it is. 5、引导让步状语从句的连接词有although, though, even if, even though。例如： Although (though) I gave him some advice, he didn’t take them. 6、引导方式状语从句的连接词有as, as if, as though。例如： You should do your homework as Tom did. 7、引导目的状语从句的连接词有so that, in order that。例如： Cherry was walking quickly so that (in order that) she could arrived at the cinema in time. 8、引导结果状语从句的连接词有so…that, such…that。例如： He ran so fast that we couldn’t keep up with him. She spoke English so clearly that all of us could understand her. 1）so…that（“如此…以致于”）表结果，其结构为： so+形／副＋that； so+形＋a(an)＋单数名词＋that； so＋many/much＋复数名词（不可数名词）+that 2）such…that（“如此…以致于”）表结果，其结构为： such＋a(an)＋形＋名词＋that； such＋形＋复数名词／不可数名词＋that 考点二：状语从句的时态。 1、在时间、条件、让步等状语从句中用一般现在时表示将来。例如： If he has time, he will come to see you. 2、before, after引导时间状语从句时，本身已能表达动作的先后关系，所以主从句都可用一般过去时代替过去完成时。
