问题
选择题
___has recently been done to provide more buses for the people ,a shortage of public vehicles remains a serious problem .
A．That
B．What
C．In spite of what
D．Though what
答案
答案：C
C “___has recently been done to provide more buses for the people”在句中做让步状语,而D. Though what错误,因为,一个单一的从句不能用两个连词引导.句意:尽管在为人们提供更多公交车这件事上,投入了很多,但是公交工具的缺乏,仍然是个问题.
