题目内容
2.The Antarctic _____ we know very little is covered with thick ice all the year round.( )A. | which | B. | where | C. | that | D. | about which |
分析 我们知之甚少的南极洲终年覆盖着厚厚的冰.
解答 答案为D.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the Antarctic的定语从句,把先行词the Antarctic带入到定语从句,完整的定语从句是"we know very little about the Antarctic";可见the Antarctic在从句中充当about的宾语.所以该题答案是D.A项which和C项that是关系代词,带入定语从句句子不完整,缺少介词,所以排除.B项where在从句中做状语,所以排除.
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.
