初中英语语法梳理和提高20状语从句讲解试题状语从句在复合句中作状语,修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理:提纲挈领,抓住重点和难点! 各类状语从句连接词(短语)一览表: 时间 when,while,as,assoonas,since,until,after,before 条件 If,unless 原因 As,because,since 地点 Where 目的 Sothat,inorderthat 结果 Sothat,so…that,such…that 让步 though,although,evenif,however 方式 As 比较 than,(not)as…as, 时间状语从句: Wheneverhecomes,hebringsafriend.他每次来都带个朋友。 条件状语从句: AslongasIamalive,Iwillgoonstudying.只要我活着,我就要学习。 原因状语从句: Sincewelivenearthesea,weenjoyniceweather.由于我们住在海边,能享受到好的天气。 地点状语从句: Putitwherewecanallseeit.把它放在我们都能看到的位置。 目的状语从句:\n Finishthissothatyoucanstartanother.把这个做完,你可以开始另一个。 结果状语从句: Hewassoangrythathecouldn'tsayaword.他气得说不出话了。 让步状语从句: Thoughheisinpoorhealth,heworkshard.虽然他身体不好,但是他工作很努力。 方式状语从句: Studentsdoastheteacherssay.学生们按照老师说的去做。 比较状语从句: Theworkisn'taseasyasIthought.这项工作比我想象得难。 例题解析:举一反三,学的更轻松! 易混引导词while,when,as的区别: when既可以指"时间点",与瞬间动词连用,也可以指"时间段",与延续性动词连用(=while)。如: Whenhecamein,hismotherwascooking. When(While)wewereatschool,wewenttothelibraryeveryday. While表示时间段,因此,while从句的谓语动词要用延续性动词。如: Pleasedon'ttalksoloudwhileothersareworking. As与when用法相似,但着重强调主句动作与从句动作同时发生,有"随着……"或"一边……一边……"之意。如: Asyougetolder,yougetmoreknowledge.随着年龄的增长,你获得的知识就越多。 2.Because,as,since的区别: Because用于表示直接原因,回答why提出的问题,语气最强;As用于说明原因,着重点在主句,常译成"由于";since表示显然的或已知的理由或事实,常译成"既然"。如: Waterisveryimportantbecausewecan'tlivewithoutit. Hedidn'tcomeyesterdayashismotherwasill.\n I'lldoitforyousinceyouarebusy. 3.such…that,so…that,sothat引导结果状语从句的区别: such是形容词,修饰名词;so是副词,修饰形容词或副词。其结构如下: 1)such+a(n)+形容词+单数可数名词+that…… 2)such+形容词+复数可数名词+that…… 3)such+形容词+不可数名词+that……。如: ThiswassuchagoodfilmthatIwenttoseeitseveraltimes. Itwassuchgoodbooksthattheysellwell. ItwassuchbadweatherthatIhadtostayathome. HespokesofastthatIcouldn'tfollowhim. Heissuchalovelyboythatwealllikehim. =Heissolovelyaboythatwealllikehim. 注:在"形容词+可数名词复数/不可数名词"结构中,当名词前有many,much,few,little表示数量的多少时,名词前用so。如: Shemadesomanymistakesthatshedidn'tpasstheexam. 练习与巩固:熟能生巧,取得好成绩! 选择合适的连接词,完成下列句子。 1.Jimspendsalotofmoneyonbooks______heisnotrich. 2.Katefellintosleep______shewaslisteningtothemusic. 3.----IsDavidatschooltoday? ----No.Heisathome______hehasabadcold. 4.Wewon'thavesupper______mymothercomesback. 5.Speaktohimslowly______hemayunderstandyoubetter. 6.______shedoesn'tcomeonSunday,I'llgofishingbymyself. 7.Itisfouryears______Ihadleftthatsmallvillage.\n 8.______theairmoves,itiscalledwind. 9.Wewillgotothepark______itdoesn'traintomorrow. 10.______littleboysdid______muchwork. 11.Therearefewnewwordsinthepassage______wecan'tunderstandit. 12.Goback______youcomefrom. 13.Hereachedthestation______thetrainhadleft. 14.----Doyouhaveaswimmingpool? ----No,wedon't.Atleast,not______big______yours. 15.Givemeyourpaper______youhavefinishedit. 16.Itisraininghard,______wehavetostayathome. 17.______youworkharder,you'llneverpassthefinalexam. 18.Lookaftertechildren______Iamout. 19.Thevillageis______faraway______Ican'tgetthereonfoot. 20.Thatis______aninterestingbook______Ican'tstopreadingit.
