不是因为英语

It is the reason of my doing sth that...... instead of......It is the reason of my getting up late that I've had a bad cold instead of staying up yesterday.例句：我晚起的原因不是昨天熬夜，而是得了重感冒用it is句型，不会头重脚轻，且强调了某事发生的真正原因，符合英语重点在前的习惯望采纳

The reason is not of you.

The reason I do it is for some other thing instead of this one

IT'S NOT YOUR FAULT.

I have reason to do sth not because of something, but because of sth.
