语法与词汇

The office, laboratory, and museum are situated at the top of the hill in which they command a fine view.

【正确答案】 C
【答案解析】

本题重点考查引导定语从句的关系代词及关系副词的用法。画线部分是定语从句修饰hill,在本句中的意思是从山顶往下看,应该用from which才对。四个选项中首先可以排除B和D,因为which是关系代词,由于先行词是表示地点的hill,所以引导从句的应该是关系副词或介词+关系代词。A项中从句的主语是单数,不能指代主句中的office,laboratory和museum。故选C,主语是代词they,指代前面二个名词。
[参考译文]办公室,实验室和博物馆都在山顶上,从这里向下看视野很不错。
[语法拓展]关系副词where在定语从句中必须作状语。也就是说,用关系副词where引导定语从句需要满足两个前提条件:一是先行词是表示地点的名词;二是关系词在定语从句中作状语。
e.g. Literature is the place where the past meets the present to contemplate the future.在文学作品里,过去与现实交汇,以思考未来。
注意:很多情况下,where所指代的先行词并不表示地点,可以把这类名词解释成“含 有抽象地点意义的名词” 。 
e.g. Remember that the best relationship is one where your love for each other is greater than your need for each other.请记住,最深的感情关系表现为彼此间的爱超过彼此间需要的爱。
