题目内容
5.___ is mentioned above,the number of violent crimes will increase this year about 15.( )A. | Which | B. | As | C. | That | D. | It |
分析 正如上文提及到的,暴力犯罪的数量今年会增长15%.
解答 答案是B;本题考查as引导的非限制性定语从句;根据句子结构判断,逗号前后的两个句子为主从句关系,前面从句中缺少的是代替主句的引导词,引导定语从句的关系词可以起着替代的作用;故判断本题为非限制性定语从句;that不引导非限制性定语从句;it 不引导从句,故排除C和D;as引导的非限制性定语从句指代的是整个主句的内容,可以放在主句前、主句中或主句之后;which也可以引导非限制性定语从句指代整个主句的内容,但是which从句只能放在主句之后,故答案用B.
点评 选择定语从句中的关系词,首先要理解各关系词的用法;然后找准先行词,将先行词带入到定语从句;最后根据先行词在定语从句中的作用判断关系词.
