题目内容
9.Living in the central Australian desert has its problems,_____obtaining water is not the least.( )A. | of which | B. | for what | C. | as | D. | whose |
分析 生活在澳大利亚中部沙漠本身存在问题,获得水不是最小的问题.
解答 答案为A.本题考查定语从句中关系词的选择.题干中空格后面是修饰和限制名词problems的非限制性定语从句,把先行词problems带入到定语从句,完整的定语从句是"obtaining water is not the least of the problems",可见从句中需要补充介词of故答案选A;what不引导定语从句,排除B;as引导非限制性定语从句必须以整个主句为先行词,排除C;whose表示"…的",不合题意,因此排除D.
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.
