2.________is known to everybody,the moon travels round the earth once every month.

　　 A.It B.As C.That D.What

　　 (NMET2001)

　　 命题意图：考查学生对定语从句中关系代词as的用法。属于五星级题目。

　　 知识依托：as引导非限制性定语从句。

　　 错解分析：A项迷惑性较大。但it是形式主语，后应用that从句作真正主语。如：It’s known to everybody that the moon travels round the earth once every month.

　　 解题方法与技巧：根据题干的逗号可以判断，空缺处应填关系代词as，引导非限制性定语从句。在这种用法中，as的意思是“正像”“像”“那样”，定语从句则表达了说话人的对某事的态度和看法。

　　 答案：B

　　 A.until B.that C.when D.where

　　 (NMET2001)

　　 命题意图：考查学生对定语从句的掌握，属于五星级题目。

　　 知识依托：先行词是表示时间的词，从句中缺少状语，通常用关系副词when。

　　 错解分析：本题有一定难度，主要是由于在先行词和定语从句之间有其他的词。

　　 解题方法与技巧：首先要找准先行词，先行词hours表示的是时间，当先行词是表示时间的词时，可能有2种情况：如果从句中缺少状语，通常用关系副词when，如题；如果在从句中缺少主语或宾语，通常用关系代词that或which。
