Question

By the end of next month,the students__middle school.

之前有人问过 但没有让我信服的回答……
A.finished B.had finished C.will finish D.have finished
老师说选C 但是我觉得没有一个正确 应该用将来完成时will be finished

Answer 1

By the end of next month 到下个月末

这个时间状语就可以看住事情还没有发生，用将来时态
By the end of next month,the students wll finish middle school

到下个月末，学生们将完成中学的学业
满意请采纳。

追问

那么用将来完成时对吗？如果对的话will finish和will be finished哪个更正确？
