选C
1.since与完成时连用,不与将来时连用
2.after如果用在这里,这句话的意思就是：在我回来之后时间就不长了...很诡异啊
3.用before的意思就是：不用担心我,我很快就会回来的.（直到我回来之前的时间不会很长）
4.when一般不会同时引导短暂性动词和延续性动词,就算有也不是这种情况,更何况还是主将从现句.come 就是短暂性动词,be就看做是延续性动词.
另外,老师应该会和你们讲not long before 和It won't be long before.这个句型,是一种固定用法,还有其他几种句型联合对比一下记忆.等到都掌握以后,再见这种题就直接选,不管意思就行.

C，这个句子的意思应该是，“不要担心我，我很快回来。”也就是说在我回来之前不会太久，所以用before。

c

你好。答案是BEFORE
语法原理------主将从现

Don't worry about me.It won't be long（主将 before (时间状语从句的连接词)I come back（从现）.

before
可以理解为：在我回来前（这段时间）不会很长了。it代替从现在到我回来前的时间

C
