我不喜欢血

我非常怕血，但是我想成为医生。

5岁的时候我跌落（跌倒了，1），把我头割(磕破了，2)。我出血了得很多(我出了很多血，3)。15岁的时候我看了（看到了，4）我的弟弟打针，我晕(晕倒了，5)。从15岁的时候我每年晕(从15岁开始，我每年都会晕血，6)。所以，我怕看血(看到血，7)。

最近我看看(看，8)关于医学的电视节目，那个节目叫House。现在，我学工程。因为我喜欢拼图。但是，工程比身体(人体学，9)简单。

我希望不怕血(我不怕血10)。我想医生是我完美的工作。

1.跌落：Maybe"跌倒了"is more better.

Simply put,"跌落" emphasize on action,such as"fall",and"跌倒了"empasize on result,such as"fall down"

2.割：磕破了

For one thing,it's a verb,what you wanna to express is a result,you need the adj. after the verb.For another,"割" usually means cut off by something like knife,so it's inapproprite here.

3.出血了得很多：出了很多血

the word order should be "predicate(出了)+object（很多血）"

4.看了：看到了

the same mistake as the second one(empasis on action or result)

5.晕：晕倒了
ditto,empasis on action or result

6.从15岁的时候我每年晕:从15岁开始，我每年都会晕血（Since I was 15,I faint at sight of blood every year)

“15岁的时候”means at the age of ten,just a year.but"每年"means every year 

7.看：看到

empasis on action or result

8.看看：看

Wu~~~how to explain it,I found Chinese is difficult already.

9.身体：人体学？

I guess you wanna say somatology?

10.我希望不怕血：我希望我不怕血

lack of subject in clause

Bye the way ,In China,we often say "晕血" instead of "怕血",which means "faint at sight of blood "

And  which TV serious you mentioned is Doctor House?I love it as well.
