5．The hottest continent，Africa has a lot of resources，______ are still undeveloped．（ ）| A． | many of them | B． | many of whom | C． | many of it | D． | many of which |
分析 最热的大洲---非洲有很多资源，大部分资源都没有被开发．
解答 答案：D
分析句子结构，Africa has a lot of resources为主句，空白处句子为非限制性定语从句，缺少主语；先行词为resources，指物，故用which．另外，定语从句引导词which和whom前可以用限制词修饰，如：many of/both/none of/+which/whom．本题需注意的是，如果是and连接两个并列句，则选A．
点评 本题考查非限制性定语从句．考生需先对句子结构进行分析，判断缺少什么成分，在结合先行词做出判断．
