　　3、There are many kinds of metals, ______.

　　C.one has its special properties D.each has its special properties

　　参考答案及解析：

　　1、D　此为固定语序，sb's not doing sth.

　　2、B　典型的表示与过去事实相反的虚拟语气句型，条件状语从句用if+主语+过去分词，主句用：主语+ would (not)/should(not)+过去分词，当省略if 时，条件从句中的had 提前。

　　3、A　本句考察独立主格结构。B没有主语;逗号不能连接两个独立完整的句子，因此排除C，D;只能选A。句意为“金属有很多种，每一种都有它的特性。”
