怎么改错？

It was raining hardly(heavily) + (in the) afternoon。On My （my）way to (去掉to)home,I saw a boy fall（felt） off the bike.
I run（ran） to the boy and then + （sent）him to the Hospital （hospital）at once.After that,I return（returned） back home.
When I got home,it was nine o'clock on（in） the evening.

回复补充： 那就是It was raining hardly(heavily) yesterday afternoon.
形容雨下的大用heavily

It was raining hardly yesterday afternoon。
（hardly改为hard，hardly意为“几乎不”，hard表程度，形容词和副词同形，表示雨下得大可以hard或heavily，如“下倾盆大雨”可译为：To rain hard.或To rain heavily.)

On My way to home,
(去掉to，home是副词，前面不带to,类似用法的词还有here\there等,"去那里"只能说go there,而不是 go to there）

I saw a boy fall off the bike.
（改为felt，首先我们来看一下动词see 的用法,see sb.do sth.或者see sb.doing sth.这里的意思是看到一个男孩从车上摔了下来,看到的时候已经摔下来了,表一种状态，不强调动作，故不用falling.因为前面动词是saw，这里"fall"应改为"fell",保持句子前后动词语态一致,)

I run to the boy and then him to the Hospital at once.
(run改为ran；
