是none of them还是none of which

是 none of them 还是 none of whichnone of which? 是考查定语从句还是考查……？请看仔细了！

He wrote a lot of novels, none of _________ translated into a foreign language.

A. them                        B. which                        C. it                        D. what

同学们看了上面一题的分析后，也许会毫不犹豫地认为此题应选 B，理由是none前没有并列连词 and 或 but，其实这次又错了。此题的最佳选项应是A，注意此句与上面一句有着本质的不同，即此句的 translated 不是谓语，而是一个非谓语动词（过去分词），所以逗号后面其实不是一个完整的句子，而是一个独立结构。假若在 translated 前加一个助动词 was，则此题应选 B(which)，构成一个非限制性定语从句。所以做这类题要特别小心，千万不要想当然，更不要受定势思维的影响。又如：

(1) I met several people there, two of _________ were foreigners. （选A）

(2) I met several people there, two of _________ being foreigners. （选B）

A. whom                        B. them                        C. who                        D. which

补充例句：

We’ve tested three hundred types of boot, none of which is completely waterproof. 我们已经测试过300种靴子，没有一种是完全防水的。

She wrote a lot of novels, none of which were popular. 她写过许多书，但没有一本是受欢迎的。
