问题补充:
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
答案:
(答案→)A. What; that
B. What; what
C. That; what
D. That; where
解析: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。
