电影侏罗纪公园的受欢迎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

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”。本题考查“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。A第三十页第三十一页，共64页。popular
