1.It is said that the old church (was build) from 1845 to 1848.
1845 to 1848限定了要用过去式,教堂应该是"被建",用被动态.
2.There (has not been) much rain in my hometown since the beginning of this month.
since要求用完成式.
3.The more careful you are ,the better you (do)in the next term.
4.Mike is 14 years old.David is 12 years old.(合并为一句)
Mike is 2 years (older than) David.

was being built 过去进行时，并且是被动
hasn't been 完成时因为后面是since
will do 因为是next time所以用过去时
older than Mike比david大两岁

1. built。 教堂是被人盖出来的。所以应该用被动。
2. has not been. 现在完成时可以表示一直持续的动作。
3. will do。 next说明还没有发生，应该用将来时。
4. older than.
