1.ThepopularityofthefilmJurassicPark,inwhichascientistclonesseveraldifferentkindsofextinctdinosaurs,proveshowtheideastruckamixtureoffearandexcitementintopeople’sheart.电影侏罗纪公园的受欢送证实了普通人对这一话题是多么感兴趣,在该电影中一位科学家克隆了几种不同的绝种恐龙。本句是一个复合句,inwhich引导非限制性定语从句,修饰“thefilm〞;how引导宾语从句,作prove的宾语。Language

PointsManypeoplewhohadseenthefilmwereafraidtogototheforestwhentheyrememberedthescenes_____peoplewereeatenbythetiger.(05,广东)

A.inwhich

B.bywhich

C.which

D.that解析:答案A。题意为“很多看过这部电影的人,当回想到人被老虎吃掉的情景时,就不敢去森林了〞。此题考查“介词+关系代词〞引导的定语从句。“peoplewereeatenbythetiger〞是定语从句,先行词thescenes在定语从句中作地点状语,表示“在这种场景中〞,所以选A。popular

adj.

popularity

n.strike

v.打;撞击;罢工strike…intoone’sheart

使……刻骨铭心Hestruckaknifeintothetraitor'sheart.

他将刀戳入卖国贼的心脏。2.Do/make/carryout/performanexperimenton/in/with…

Basedonwhatweknownow是过去分词短语作状语,其逻辑主语一般和句子的主语相一致。_____byagreaterdemandforvegetables,farmershavebuiltmoregreenhouses.(07,浙江)

A.Driven

B.Beingdriven

C.Todrive

D.Havingdriven解析:答案A。题意为“由于受到更大的蔬菜量需求的推动,农民修建了更多的温室〞。根据by,应用被动,排除C和D。根据后边的完成时态,驱动力已经有了,不是正在推动,应选A。Fillintheblankswiththewordsgiven.
