这道题涉及where从句,是一道极易错的题: When you read the book, you’d better make a mark __________ you have any questions. A. which B. at which C. where D. that http://yingyu.chazidian.com 分析:此题应选 C。容易误选 A,B,D,误认为这是定语从句。假若这是定语从句,A(which) 和 D (that) 应是关系代词,但它们却不能充当定语从句中的主语或宾语,故不成立。至于 B (at which),也不合语法,因为其中的介词at无法与从句中的任何一个词发生联系。 此题选 C,这里的 where 是引导地点状语从句的连词,意为“在……的地方”,全题意为:你读这本书时,最好在有问题的地方作一个记号。类似例子: There were lots of parks where I lived. 我住的地方有许多公园。 You should let your children play where you can see them. 你应该让你的孩子在你能看到的地方玩。 After the war, a new school building was put up where there had been a theatre. 战后人们在曾经是剧院的地方建了一幢新教学楼。 You can find your umbrella where you left it. 你可以在你放伞的地方找到你的伞。 在以下结构中,where 暗示一种条件(=if)。如: Where there is a will, there is a way. 有志者事竟成(http://yingyu.chazidian.com)。 Where you find high wages, you’ll generally find high prices. 工资高的地方通常物价就高。
