Question

____ we want to know is whether we must finish the work ____ you assigned last week.

A．What; that

B．What; what

C．That; what

D．That; where

Answer 1

A

试题分析：句意：我们要知道的是是否我们必须完成这项你上周分配的工作。这里第一空是what引导的主语从句，它在从句中做主语；that在主语从句中不作成分，故排除CD；第二空是that引导的定语从句，先行词是work，关系词在从句中作宾语，what不能引导定语从句，故排除B。故选A。
点评：本题难度适中。定语从句和连词是高考常考的知识点，判断用哪个连词或关系词除了必须要分析句子成分外，还需理解句子的语境，只有正确理解句子的语意才能做出正确的判断。
即学即练：He has lots of friends, only a few of  ______ invited to his wedding.
A. whom          B. them            C. which          D. who
解析：B。句意：考查定语从句和其他结构的区别。only a few of them invited to his wedding是独立主格结构，此结构不是完整句子，因此不能选其他引导词。
