九年级英语(人教新目标)全一册 复合句期末专项 复习课件
展开一、宾语从句 当一个句子在复合句中充当宾语时,该句叫宾语从句。其考点主要是宾语从句的引导词、语序及时态等。 1.宾语从句的语序 无论引导词是that, if, whether 还是特殊疑问词,宾语从句的语序必须用陈述句语序。如: D yu knw what he is ding? 你知道他正在做什么吗?
2.宾语从句的引导词(1)由 that 引导的宾语从句这种宾语从句一般为陈述句,that 在句中不充当任何成分,一般可省略。如:I didn’t knw (that) he had cme back frm Shanghai.我不知道他已经从上海回来了。
(2) 由 if 或 whether 引导的宾语从句 if 和 whether 表示“是否”,在句中不作任何成分,通常可以互换。(从句中有 r nt 时,只能用 whether)。如: I wnder whether r nt he has cme back. 我想知道他是不是回来了。
(3)由疑问代词或疑问副词引导的宾语从句疑问代词 wh, what, which, whm 在从句中作主语或宾语等。疑问副词 when, where, why, hw 等在从句中作状语。如: D yu knw where he lives? 你知道他住哪儿吗?
3.宾语从句的时态 (1) 主句时态是一般现在时,从句谓语动词根据具体情况使用任何一种时态。如: He says that he’ll pass the exam. 他说他会通过考试的。 He says that he came back yesterday. 他说他昨天回来的。
(2)主句谓语动词是一般过去时,从句谓语动词用相应的过去时态。如: She said that there were many bks n the desk. 她说桌上有很多书。 He tld me (that) he had finished his wrk. 他告诉我他已经完成了工作。
(3)如果从句是客观真理,从句时态不受主句时态影响,用一般现在时。如: The teacher tld his students that the earth ges arund the sun. 老师告诉学生地球围绕太阳转。
二、状语从句 一个句子在复合句中作状语时,该句叫状语从句。其考点是从句引导词及主从句时态一致问题。 1.时间状语从句 由when, befre, after, until, as sn as, while, as, since等引导的状语从句叫时间状语从句。如: I’ll call yu as sn as he cmes back. 他一回来我就给你打电话。 He didn’t g t bed until he finished his hmewrk. 他直到做完作业才睡觉。
2.条件状语从句由 if (如果)引导的状语从句叫条件状语从句。如:We’ll g there by bike if it desn’t rain tmrrw.如果明天不下雨,我们就骑自行车去那里。
3.其他状语从句及引导词
●主句与从句时态一致问题在时间状语从句和条件状语从句中,主从复合句时态一般有三种情况: (1)主现从现:若主句是祈使句或主句中有情态动词时,从句用一般现在时表示将来。如: Be careful when yu crss the rad. 过马路时要小心。
(2)主将从现: 主句用一般将来时,而从句用一般现在时。如:I will visit my gd friend when I have time.我有时间时,我将去看望我的好友。(3)过去时态: 若主从句都是在叙述过去的事情,主从句可以用一般过去时或过去进行时。如:Mther was cking when I gt hme yesterday. 昨天我到家时,妈妈正在做饭。
三、定语从句 在复合句中,修饰某一名词或代词的从句叫定语从句。其考点在关系词that, which, wh的选用。1.that既可指人,也可指物。在定语从句中作主语或宾语,作主语时不可省略,作宾语时可省略。如:The train that has just left is fr Shanghai. (that 指物,作主语,不可省略)刚刚离开的那列火车是开往上海的。
2.which 指物,在定语从句中作主语或宾语,作主语时不可省略,作宾语时可省略。which和 that一般可互换。如: The cmputer which/that I wanted t buy was sld ut. 我想买的那台电脑卖光了。
3.wh, whm指人。wh在定语从句中作主语或宾语,whm在定语从句中作宾语。在口语中,有时可用wh或 that代替 whm, whm 也可省略。如:The girl wh plays the pian very well is his daughter. (作主语)那位钢琴弹得很好的女孩是他女儿。 Where is the girl (wh/whm) yu met last night? 你昨晚遇到的女孩在哪儿?
●当关系代词指物时,下列情况只能用 that而不能用which:(1)先行词被序数词或形容词最高级修饰时。如:It is the largest map that I have ever seen.它是我见过的最大的地图。(2)当先行词被 the nly, any, n, all, little, few, the very等词修饰时。如:This is the nly thing that yu shuld care abut. 这是你应该关心的唯一的事情。
(3)当先行词为all, smething, everything, nne, much, n ne, the ne等代词时。如:There is nthing that belngs t yu in the rm. 这个房间没有属于你的东西。(4)当先行词同时含有人和物时。如:We talked abut the persns and things that we remembered at schl.我们谈到了我们还记得的学校中的人或事。
(5)主句是以wh或which引导的特殊疑问句。如:Which f the bks that yu bught yesterday was written by M Yan? 你昨天买的哪本书是莫言写的?
