答案与解题思路
1.D.
解题思路：有逗号是非限制性定语从句，在句首，故选D.注意句型
Itisexpected that+……中间没有逗号，如果What isexpected引导主语从句，则后
面缺少谓语， which引导非限制性定语从句指代整个主句时不能放在句首。
2.A.
解题思路：虽然 as与which引导非限制性定语从句都指代整个主句，都可
在主句后，但是as is known (to all)是固定搭配。故选A.
2.D.
解题思路：as引导的非限制性定语从句 在主句前，指代后面整个主句，注
意it引导形式主语的结构是It is known to all that+从句……,句中没有逗号。
