D.has been finished
【精析】B A. will finish 是一般将来时主动语态;B. will be finished 是一般将来时被动语态;C. have been finished 现在完成时被动语态;D. has been finished 是主语是单数第三人称的现在完成时被动语态。本句的主语 work 和finish 是被动关系;根据后面的时间 in two days(两天后)，可知用一般将来时被动语态，故选 B。
2.A new shoe factory will_____in this part of the city.
A.be building
B.be built
C.build
D.being built
【精析】B 根据句中有will，所以用将来时的被动，结构是will be done。故选 B。
3.As a new kind of transport service, shared bikes_____in more Chinese cities in the following years.
A.use
B.are used
C.will use
D.will be used
【精析】D use:使用,动词原形;are used:一般现在时的被动语态;will use: 一般将来时;will be used:一般将来时的被动语态。根据句中的时间状语 in the following years 可知,这里表示将来的事情，应用一般将来时态，并且句子的主语 shared bikes 和动词 use 构成被动关系，应用被动语态,故应选 D。
4.—What if I have to go there and know nothing about it?
—If I _____you, I would try to find some information about it on the Internet.
A.am
B.was
C.will be
D.were
【精析】D 根据 I would try to find可知主句用的是 would+do，可知这是对现在事实的假设的虚拟语气，因此 if 引导的条件状语从句用一般过去时，根据虚拟语气的用法 be 动词在从句中用 were，故选 D
5.It is reported that half of the China's population ___________ famers in 2015.
A.are

【精析】D population 作主语用时,谓语动词常用第三人称单数形式。当主语是表示人口百分之几时，谓语用复数。再由 in 2015 可知应用一般过去时。故选 D。
