问题
选择题
The social worker asked Daniel ______________.
A．if did he have any problem
B．who he played football with the day before
C．how long he usually spent on his homework
D．what he will do this summer
答案
答案：C
题目分析：句意:这个工人问Daniel他通常花费多长时间做作业。本题考查的是宾语从句，宾语从句中应该用陈述语序，故Ａ不对；D选项中的时态不对，因为句中谓语动词用的是过去时态，所以宾语从句中也应该用过去时态才对。故选C。
