Question

He抯 a doctor, _______ was his wife before she had children .

[　　]

A． it　　B． as　　 C． that　　　 D． which

Answer 1

答案：B
解析：

测试语言点 ：As is…的用法 ，及其与it， that， what用法的区别。　 　要吸取的经验 ： as is known … , it is known … , that is known , what is known …显然都是书面英语。这四个词，都可以用在此题 ，表达大同小异的句义： As is known to everybody, the moon travels round the earth once every month. It is known to everybody that the moon travels round the earth once every month. The moon travels round the earth once every month. That_is known to everybody. What_is known to everybody is（the fact） that the moon travels round the earth once every month .

提示：

此题与2001年之（34）题相似 　　________ is known to everybody, the moon travels round the earth once every month . A . It　　B． As　　 C． That　　　 D． What 　　该试题答案 ：B 　　※※2004年北京卷（34）题和江苏卷（33）题都测试了As的用法。
