most of them還是most of whom

請先看題：

He wrote a lot of novels, most of _________ were popular.

A. them                   B. whom                  D. that                     D. which

【分析】此題最佳答案為D，但很容易誤選A。假若單獨看 He wrote a lot of novels 和 Most of them were popular 這兩句話，它們并不錯，但將它們放在一起用逗號連接就不甚妥當了。因為，英語句子按其結構來劃分，可分為簡單句、并列句、復合句和并列復合句四種，也就是說，一個規范的英語句子，從結構上說，它必須隸屬以上四類句型之一。但上面一題若選A，則它既不是簡單句(因為它有兩個主謂結構)，也不是并列句(因為它沒有并列連詞)，也不是復合句(因為它沒有主從句之分)，當然它更不是并列復合句，所以選A是錯誤的。可以選D，是因為空白處填了 which 之后，后一句即成了一個非限制性的定語從句，前一句即為主句，整個句子即為一個復合句。比較以下各句：

(1) He wrote a lot of books, and most of them were popular.

句中用了并列連詞，整個句子為并列句。

(2) He wrote a lot of books, most of which were popular.

后一句用了 which，使之成為定語從句，整個句子為復合句。

(3) He wrote a lot of books, most of them being popular.

后一句用了非謂語動詞 being，故逗號處不用并列連詞，整個句子為簡單句。
