I will go as soon as I have finished my lesson.这里的从句为什么要用现在完成时而不用原形?

用as soon as I have finished my lesson和as soon as I finish my lesson两者都可以的.
再问：有什么区别
再答：因为finish本身就有完成的意思，所以用have finished和finish是一个意思，没有区别。
as soon as＋现在完成时表示一完成...就...，as soon as＋一般现在时表示一...就...
例：I will ring you up as soon as I get there.我一到那里就给你打电话。
I will go with you as soon as I have done my homework. 我一做完作业就和你出去。
