2021届高考二轮英语备考专项冲刺学案：专题14【状语从句】 (原卷版+解析版)

2021届高考二轮英语备考专项冲刺 专题14 【状语从句】语法增分攻略原题版 解题指导·触类旁通 寻方法，求策略，掌握“套路” 1．确定是状语从句 设空前后两个句子之间含有一定的逻辑关系时，应用状语从句的引导词。 2．两个关键点突破状语从句 (1)重点关注几组引导词用法 原因状语从句 as, because, since, now that 地点状语从句 where, wherever 目的状语从句 so that, in order that, for fear that, in case 结果状语从句 so that, so ... that ..., such ... that ... 条件状语从句 if, unless, so/as long as, in case 让步状语从句 though/although/while, as, even if/though, however, whether ... or ..., whatever, whoever, no matter how/what/which (2)利用时间先后法巧定时间状语从句引导词 ①动作同时发生： when、 whenever、 while、 as等。 ②动作接连发生： as soon as、 the minute、 immediately、 once等。 ③先后发生： before、 after等。 ④动作的延续： since。 ⑤动作的终止或开始： till/until。 3．状语从句易错点： ①such ... that ... 结构中such修饰名词；so ... that ...结构中so修饰形容词或副词。 ②so＋many/much/few/little(少)＋名词＋that ... ③the moment/the instant/every time/immediately 等相当于连词，引导时间状语从句，不能与when连用。 ④not ... until中的not可能换为never, no等表否定的词构成陷阱。 4.析三大从句，辨七大易混点 易混点(一)　定语从句和并列句 1．She has many novels, some of _____ are interesting. 2．She has many novels, and some of _____ are interesting. [分析]　 1.which　which引导定语从句，修饰先行词novels, “some of which”在从句中作主语。 2．them　此句为and引导的并列句。 [点拨]　定语从句与并列句的主要区别：句中若有and, but, so等并列连词或分号则为并列句，此时不需要再填引导词。 易混点(二)　定语从句和状语从句 1.①We young people should go to the place _____ is in need of help. ②We young people should go _____ we’re most needed. [分析] ①which/that　关系代词which/that引导定语从句，修饰先行词“the place”，且在从句中作主语。 ②where　where引导地点状语从句，修饰主句谓语动词go。 [点拨]　定语从句与地点状语从句的主要区别：定语从句有表示地点的先行词，而地点状语从句则没有；定语从句修饰的是先行词，地点状语从句修饰的是谓语动词。 2.①I will always remember the days _____ I lived with my grandparents in the countryside. ②I always remember the days in the countryside _____ I see the photo of my grandparents. [分析] ①when　when引导定语从句，修饰先行词“the days”，且在从句中作状语。 ②when　when引导时间状语从句，修饰谓语动词remember。 [点拨]　定语从句与时间状语从句的主要区别：定语从句有表示时间的先行词，而时间状语从句则没有；定语从句修饰的是先行词，时间状语从句修饰的是谓语动词。 3.①This is such an interesting work of art _____ all of us like. ②This is such an interesting work of art _____ all of us like it. [分析] ①as　such...as引导定语从句，as在定语从句中作like的宾语。 ②that　such...that引导结果状语从句。 [点拨]　定语从句与结果状语从句的主要区别：the same...as与such...as引导定语从句， as在从句中充当一定的成分；such/so...that...引导结果状语从句，that在从句中不作成分。 易混点(三)　定语从句和名词性从句 1. ①_____ is known to everybody, the moon travels round the earth once every month. ②__ ... ...
