?請看下面這道題：
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(dú)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(dāng)了。因?yàn)?，英語句子按其結(jié)構(gòu)來劃分，可分為簡單句、并列句、復(fù)合句和并列復(fù)合句四種，也就是說，一個規(guī)范的英語句子，從結(jié)構(gòu)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?yàn)樗袃蓚€主謂結(jié)構(gòu))，也不是并列句()，也不是并列句因?yàn)樗鼪]有并列連詞)，也不是復(fù)合句(因?yàn)樗鼪]有主從句之分)，當(dāng)然它更不是并列復(fù)合句，所以選A是錯誤的?？梢赃xD，是因?yàn)榭瞻滋幪盍?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(fù)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(fù)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。
