    中考语法专题十三 从句 第二部分 语法复习 中考语法专题十三 从句 在复合句中,由时间连接词引导的状语从句叫做时间状语从句。 1.时间状语从句 (1)引导词:when, while, as, before, after, as soon as, until, since. 如:Mozart started writing music when he was four years old. He visited a lot of places while he was traveling . He left the classroom after he had finished his homework the other day. (2)一般情况下主句是将来时,从句要用一般现在时。 如:I will tell him as soon as he comes back tomorrow. I will not leave the classroom until my teacher checks my homework. 中考语法专题十三 从句 (3) not...until…. / not… before…/ … after… 的同义替换。 如: I will not go to bed until my mother comes back. =I will not go to bed before my mother comes back. =I will go to bed after my mother comes back. 2.条件状语从句 (1)引导词:if, unless. (2)if...not与unless及or的同义句转换。 (3)主句为将来时 / 一般现在时,从句用一般现在时代替。 如: If it doesn''t rain tomorrow, we will go fishing . = Unless it rains tomorrow , we will go fishing.

(= in order that ) I opened the window so that fresh air might come in. (= in order that ) 中考语法专题十三 从句 5.结果状语 (1) 引导词:so...that, such...that. (2) so与such的区别 so 形 a/an 名 such a/an 形 名 so many / much / few / little 形 名 such 形 不可数名词/可数名词复数 一个如此小的男孩 so young a boy( 只能用于单数名词) = such a young boy 一些如此有趣的书 such interesting books (3) so adj. (adv) that与too. adj.(adv) to do 和ad j. (adv) enough to间转换 中考语法专题十三 从句 他是如此小的男孩以至于不能去上学。 He is so young a boy that he can’t go to school. = He is such a young boy that he can’t go to school. = The boy is so young that he can’t go to school. = The boy is too young to go to school. = The boy is not old enough to go to school . 6.比较状语从句 (1)引导词:as...as, not as (so)...as, than ★(2)not as (so)...as与than的同义句替换。 ★(3)as...as, not as (so)...as中间用形容词 或 副词的原形。 中考语法专题十三 从句 7.让步状语从句 (1)引导词:though, even though. ★(2)though不能与but连用。 如:Sam did quite well in the exam although he was unprepared. = Sam was unprepared , but he did quite well in the exam. 8.地点状语从句 (1)引导词where, wherever. ★(2)wherever=no matter where 中考语法专题十三 从句 9.方式状语从句 :引导词:好像as if, as though. ★定语从句 定语从句是用来修饰限定名词或代词的从句, 1.关系代词作主语 (1)关系代词在定语从句中作主语时 , 往往用who, that 和 which 引导定语从句。 先行词指“人”时,用who 或that;先行词(被修饰词)指“物”时,用 that 或 which.

She asked me what was the matter with me ? ( what was the trouble with me / what was wrong with me ) She asks me what happened to me? She asks me which is the way to the post office ? 考点三:考查时态 主句 从句 一般现在时 该用什么时态就用什么时态 一般过去时 用过去的时态: 一般去时 was / were 或 V ed(过去式) 过去进行时 was / were V ing 过去将来 would V原 过去完成时 had P.P. ( 过去分词) ★★注意 if when If/ When 从句的时态 条件/时间 状语从句 如果,假如 当……的时候 一般现在时 宾语从句 是否 什么时候 一般将来时 考点四:其他常见考点 “Could you tell me...?”是用来征询对方意见,并不表示过去,所以此时宾语从句的时态可根据具体语境而定。 Could you please tell me where the post office is ? 请问邮局在哪儿? 如果宾语从句说的是客观真理、自然现象等,无论主句的时态是什么,从句都要用一般现在时。 Tom told me New York is the largest city in America. 汤姆告诉我纽约是美国最大的城市。
