选择题
It is convenient for people to work by subway. It’s said that The Line 4 subway in Chengdu _______by the time of 2018.
A．will be built
B．would be built
C．will have been built
D．would have been built
答案
答案：C
题目分析：句意：人们乘坐地铁上班很方便。据说在成都地铁4号线将在2018年以前建成。由时间状语by the time of 2018可知该用将来完成时态，又The Line 4 subway是build这一动作的承受着，该用被动语态，所以选C。
