Question

My uncle has a lot of books, _______ are about computer science and technology.

A．most of them	B．most of that
C．most of which	D．a(chǎn)nd most of which

Answer 1

C

試題分析：考查定語從句。本題定語從句的先行詞是a lot of books，定語從句中which指代先行詞作為of的賓語。That不能放在介詞的后面，them不能引導(dǎo)定語從句。D項(xiàng)中因?yàn)橛辛薬nd說明是一個并列結(jié)構(gòu)。which應(yīng)該改為them。故C正確。
點(diǎn)評：定語從句的解題關(guān)鍵是分析句子成分，關(guān)系代詞that, which, whose, whom, as， who在句中做主語，賓語，表語或者定語；where, why, how在句中做狀語。要分析句子成分，看缺少什么成分，就選用相應(yīng)的關(guān)系詞。
