【语法感悟】1.句①介词during和关系代词which引导。2.句②介词among和关系代词whom引导。3.句③介词for和关系代词which引导。4.句④介词in和关系代词which引导。定语从句定语从句定语从句定语从句 语法精讲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。如果指人,用“介词+whom”;如果指物,用“介词+which”。1.“介词+关系代词”的几种常见结构(1)“介词+which”在定语从句中分别可作时间、地点和原因状语,代替相应的关系副词when,where和why。Ioftenthinkofthemomentatwhich(=when)IsawtheUFO.我常常想起我看见不明飞行物的那一刻。 Restaurantscanofferachoiceofmusicalongwiththevariousfoodchoicesonthemenu,givingcustomersabetteratmosphereinwhich(=where)theyaredining.餐厅可以在菜单上提供音乐选择和各种食物选择,给顾客更好的就餐气氛。Thereasonforwhich(=why)Youthisverypopularamongstudentsisthatitcarriesalargeamountofencouragingarticles.《青年报》在学生中很受欢迎的原因是它刊登了很多鼓舞人心的文章。 (2)“代词/数词+of+which/whom”引导定语从句。这个结构中,代词常常为all,each,one,many,much,most,some,none,both等,“代词+of+which/whom”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“of+which/whom”置于代词或数词前。Hehaslotsofhobbies,oneofwhichisswimming.他有很多爱好,其中之一是游泳。Theoldmanhasthreesons,allofwhomcareabouthim.那位老人有三个儿子,他们都很关心他。 (3)“the+名词+ofwhich/whom”引导定语从句。这个结构中,ofwhich/whom充当定语,修饰前面的名词,整个结构相当于“whose+名词”引导的定语从句。InancientChinalivedanartistthepaintingsofwhom(=whosepaintings)werealmostlifelike.中国古代有一位艺术家,他的画几乎栩栩如生。Ontheblackboardtheteacherwroteasentence,themeaningofwhich(=whosemeaning)Idon’tunderstand.老师在黑板上写了一个句子,句子的意思我不明白。 (4)“the+形容词比较级(最高级)+of+which/whom”引导定语从句。Therearetwobuildings,thelargerofwhichstandsnearlyahundredfeetinheight.这儿有两座建筑物,较大的那座几乎有100英尺高。 2.关系代词前介词选择的原则(1)根据定语从句中的谓语动词或形容词和介词的搭配关系选择。Chimpswillchecktoseeiftheyhavetheattentionoftheanimalwithwhichtheywishtocommunicate.黑猩猩会检查自己是否得到了想要与之交流的动物的注意。(2)根据定语从句中介词与先行词的搭配关系选择。Manylessonsarenowavailableonline,fromwhichstudentscanchooseforfree.许多课程现在都可以在网上找到,学生们可以从中免费选择。 (3)根据句子的意思选择。I’mwritingtoexpressmygratitudetoyou,withoutwhosehelpIwouldnothavegainedgreatadvanceinEnglish.我写这封信是为了表达我对你的感激之情,没有你的帮助,我的英语就不会有很大的进步。 学以致用•随堂检测全达标
