用there be 改写There are two cinemas in the town (next year)

为你解答.
There are two cinemas in the town. (用next year改写)
There will be two cinemas in the town next year.
明年城里会有两个电影院.
解释：要把句子改为将来时,加上助动词will与be动词的原形连用.拜托，还用there be结构没错，There will be ……（这是there be的将来时，意思为将会有。）也可以说成There are going to be two cinemas in the town next year.为什么是there are going to be 而不是there is going tobegoing这和后面的主语有关系吗？后面的主语选用的应该是going to 后面的be 吧？和前面有关系吗？请赐教，谢谢是和主语有关的。主语是两个影院，要算复数。后面的be动词是原来的there be结构的，要用原形。
