展开Sectin Ⅱ Discvering Useful Structures
语法点拨一、定语从句的概述
This is the family which is planning t mve t the city.(which引导的定语从句)这是要搬进城里的一家。世界上最长的跨海大桥港珠澳大桥,在星期三的九点开始通车。I grew up in a small village where everybdy knew me.(where引导的定语从句)我在一个小镇上长大,那里的每一个人都认识我。
先行词与关系词1.先行词:被定语从句修饰的词叫先行词。2.关系词:引导定语从句的词叫关系词。3.关系词通常有下列三个作用:(1)引导定语从句;(2)代替先行词;(3)在定语从句中担当一个成分。4.关系代词在从句中作主语、宾语、定语或表语;关系副词在从句中作状语。
单句语法填空①(2019·全国卷Ⅲ)They were well trained by their masters ______ had great experience with caring fr these animals.②(2019·浙江高考)On the edge f the jacket, there is a piece f clth _____________ gives ff light in the dark.③(2019·北京高考)The students benefiting mst frm cllege are thse ______ are ttally engaged (参与) in academic life.
that/which
④(2018·天津高考)Kate, ________ sister I shared a rm with when we were at cllege, has gne t wrk in Australia.⑤(2019·江苏高考)We have entered int an age _______ dreams have the best chance f cming true.⑥(2019·天津高考)Their child is at the stage ________ she can say individual wrds but nt full sentences.
二、关系代词和关系副词的区别定语从句中关系代词和关系副词的判断方法:
I visited the village where many children culdn’t g t schl because f pverty.(作状语)我参观了因为贫困很多孩子不能上学的村庄。I visited the village which/that is famus fr its beautiful scenery.(作主语)我参观了因美丽的景色而闻名的村庄。
单句语法填空①(2019·全国卷Ⅰ)One afternn _______ I was in primary schl, I was walking by the schl playgrund.②(北京高考)The little prblems _____________ we meet in ur daily lives may be inspiratins fr great inventins.③The reasn ______ he resigned was that he didn’t get n well with the bss.
④(2018·全国卷Ⅱ)Thursday sees us make the shrt jurney t Paris ________ we will visit Disneyland Paris park.⑤Picass painted many pictures ________ the main clrs are blue and pink.
三、介词+关系代词当关系代词在定语从句中作介词的宾语时,我们通常用“介词+关系代词”引导定语从句。关系代词可用which、whm或whse。先行词指物时,用which;先行词指人时,用whm;定语从句中缺少定语时用whse。在这个结构中,介词的确定的原则是:(1)依据定语从句中动词或形容词等所需要的某种习惯搭配来确定。He is the man n whm yu can rely.他是你可以信赖的人。Jack intrduced t me his friend with whm I was nt very familiar.杰克向我介绍了我不很熟悉的那个朋友。
(2)依据与先行词搭配的具体意义而定。I’ll never frget the day n which we wrked tgether in the cuntryside.我不会忘记我们一起在乡下工作的日子。(3)根据所表达的意思来确定。The clever by made a hle in the wall, thrugh which we culd see what was happening inside the huse.这个聪明的孩子在墙上挖了一个洞,透过它我们可以看到屋里发生的事情。
(4)表示“所有”关系或“整体中的一部分”时,通常用介词f。Julie was gd at German, French and Russian, all f which she spke fluently.朱莉擅长德语、法语和俄语,这三样她都说得流利。
在定语从句中,有一些含介词的动词短语不可拆开使用,如lk after,lk fr等。The babies whm the nurses are lking after are very healthy.(正确)The babies after whm the nurses are lking are very healthy.(错误)
介词+关系代词的常见句型(1)“代词+f+which/whm”引导非限制性定语从句这个结构中,代词常常为all,each,ne,many,much,mst,sme,nne,bth等,“代词+f+which/whm”通常在定语从句中作主语,说明整体中的一部分。有时候也可把“f+which/whm”置于代词前。It is reprted that tw schls, bth f which are being built in my hmetwn, will pen next year.据报道,在我的家乡两所学校都正在建设中,将于明年投入使用。
(2)“数词+f+which/whm”引导定语从句这种结构常用来引导非限制性定语从句,有时候也可以把“f+which/whm”置于数词前。数词包括百分数和基数词。(3)“the+名词+f which/whm”引导非限制性定语从句这个结构中, f which/whm充当定语,修饰前面的名词,整个结构相当于“whse+名词”引导的定语从句。
(4)“the+形容词比较级(最高级)+f+which/whm”引导非限制性定语从句There are tw buildings, the larger f which stands nearly a hundred feet high.这儿有两座建筑物,较大的那座几乎有100英尺高。
用“介词+关系代词”填空①He wrte many children’s bks, nearly half ___________ were published in the 1990s.②I wish t thank Smith, ________________ help I wuld never have gt this far.③English is a language shared by several cultures, each ___________ uses it differently.④The children, all __________ had played the whle day lng, were wrn ut.
withut whse
四、定语从句中关系词的省略关系词可以省略的几种情况(1)定语从句的关系词在定语从句中作宾语或表语时,关系词通常可省略。I have taken with me the tw bks (that/which) yu asked me t return t the City Library.我把你要我送还给市图书馆的那两本书带走了。
(2)先行词是way,reasn,time,place等且它们在定语从句中分别作方式、原因、时间和地点状语时,其后定语从句的相应关系词that/in which,why/that,when,where等可以省略。The way (that/in which) yu lk at the prblem is wrng.你看待问题的方式是错误的。
(3)由and,but,r等并列连词连接两个或两个以上的定语从句修饰同一个先行词时,第一个关系词可以省略,但第二及以后的关系词一般不可以省略。I want a gift (that/which) my friend has put sme thught int and that I d need.我想要一个我朋友花费心思的礼物,并且是我确实需要的礼物。
划掉可以省略的关系词①I dn’t knw the exact time when the sprts meet takes place.when②That was the way that she wrked the prblem ut.that③The man whm yu spke t just nw is ur English teacher.whm
④The exact year which Angela and her family spent tgether in China was 2008.which⑤I believe the reasn that Mary gave fr her absence frm the schl.that
