同学你好~
e After the crash, two angry drivers got out of their cars.
The first driver asked sarcastically whether the other man always
slept when he was driving. He was on the wrong side of the road.
Shouting angrily, the second driver asked the first one whether
he had noticed that the road was being repaired. He was driving
on the wrong side of the road when the first man hit him because
the other side was full of holes. He asked him if he had seen the
traffic sign. The first driver then asked whether he had ever driven
a car before. He said that he had been driving a car for twenty
years. There were, he added, good driving schools for people like
the other driver. There they taught you lots of things ---- how to
drive a car, for instance. Grateful for this information, the
second man angrily informed the first one that he happened to be
a driving instructor.  这部分完成得很好。

f 1 If you hadn't been more careful, you might have been knocked down by a car.  
If you hadn't played on phone, you might have been knocked down by a car. 如果你没有玩手机，你可能会被一辆车撞倒。这个句子不通顺。

2 If she hears anything, she will let you know.  第二句后半句是将来时，说明这是真实条件句，前面应该是If she is in trouble
3 If you were in my position, what would you do?

祝同学学习进步~
