In the past,we also issue letters before students' final year began to let them know what they needed to take in the final year to be OK,but we don't do that anymore.
这句话里面的issue 怎么不是过去式啊?began 是把前面的整句话当成是主语么?可以分析下这句话语法么?

in the past,是状语
we是主语 also issue是谓语貌似前面省略了 should
letters是宾语
before students' final year began 是时间状语从句修饰 issue
to let them know是目的状语从句修饰issue
what they needed to take in the final year to be OK,是宾语从句作 know的宾语
but we don't do that anymore是并列句.
句子意思
过去,在学生的最后一学年开始之前我们将给学生发函让他们知道为了顺利毕业他们在最后一年需要做什么,但我们现在不这样做了.
再问： began为什么不能用begin呢？
再答： began不能用begin因为主语是 students' final year 这是指以前的情况你的意思是前面为什么可以用issue 我认为是省略了 should 而 before 从句是时间状语从句这里时态只能用一般过去时与主将从现的道理一样。也就是主句用过去将来时时间状语从句用一般过去时
