54单元语法
55v.-ing形式作主语或宾语1.Peoplespendmanyyearslearningaboutfavoritesportsand________(practice)howtodothemwell.答案:practicing考查非谓语动词。spend...(in)doingsth.表示“花费……做某事”,根据and可知,空处应与learning并列,作省略了的介词in的宾语。
562.________(bring)upinthecountrysidemadeMr.Wilsonveryhardworkingwhenhewasveryyoung.答案:Beingbrought考查非谓语动词。句意:Mr.Wilson在乡下被抚养长大,这使他在很小的时候就很勤劳。分析句意及句子结构可知,bringup与Mr.Wilson为逻辑上的动宾关系,又因为句子缺主语,故用Beingbroughtup。
573.________(examine)twiceayear,whetheritisacar,abusoratruck,isarulethateverydrivermustobeyinthiscity.答案:Beingexamined考查非谓语动词。句意:无论是汽车,公交车还是卡车,每年检查两次是这个城市的每个司机都要遵守的规则。根据句意可知此处应用examine的现在分词的被动式Beingexamined作句子的主语。
584.Tothisday,Ihaveahardtime________(let)othersbefondofme.答案:letting在句中haveahardtime(in)doingsth.为固定结构,表示“做某事有困难”。5.Shecan'thelp________(clean)thehousebecauseshe'sbusymakingacakeinthekitchen.答案:toclean考查固定用法。句意:她不能帮忙打扫房间,因为她正在厨房忙着做蛋糕。help(to)dosth.“帮忙做某事”,是固定短语,符合句意。注意:此处不是can'thelpdoingsth.“禁不住做某事”这个固定词组。

601.(2014·安徽改编)It'sourhopethatwewillplayagreaterroleinthemarketplaceand________,supplymorejobs.答案:therefore考查副词。句意:我们希望我们会在工作市场上起更大的作用,因此提供更多的工作。

623.(2014·陕西改编)Wewouldratherourdaughter________(stay)athomewithus,butitisherchoice,andsheisnotachildanylonger.答案:stayed本题考查虚拟语气。句意:我们宁愿我们的女儿和我们一起待在家里,但是那是她的选择,她已经不再是一个小孩子了。wouldrather后接that从句时,要用虚拟语气,如果与现在或将来事实相反,从句用一般过去时态;如果与过去事实相反,从句用过去完成时。根据后面的itisherchoice可以判断这件事情还没发生,因而从句用一般过去时。
634.(2013·浙江改编)Bearsbuild________fatstoresthroughoutthesummerandfalltohaveenergyenoughtolastthemthroughtheirwintersleep.答案:up句意:狗熊在夏天和秋天开始脂肪的储存以使他们有足够的能量来度过冬眠。5.(2011·江苏改编)Itsoundslikesomethingiswrongwiththecar'sengine.If________,we'dbettertakeittothegarageimmediately.答案:so本题考查省略。句意:听起来好像是车的发动机出毛病了。如果这样的话,我们最好立刻把它带到修车厂去。ifso“如果这样的话”。
