英语翻译I am a 14 years OLD student,the daily learningtasks are

第一句：太长了也就是英文中的run-on sentence.不如把第一句变成两个句子?句子最后有句号
第二句：playing 不是 paying.并且我发现你在列举事物的时候没有标点（逗号）.so on 后面有句号.
第三句：each color IS like 不是 Each color just like.elf的复数是elves.并且是i think they are LIKE little elves.
第四句：each song THAT contains many stories 结束.
错误太多了.我把你的文章都给改对了.如下：
I am a 14 years old student,the daily learning tasks are heavy,but life after school life is full of joy.It brings me a lot of fun and takes away my sadness.
I have many hobbies,such as playing the piano,drawing,do some sports and so on.I Iike art because I think each color is like expressing different feelings to others.I think they are little elf elves
At first,I do not like playing the piano,but as As I grew older,I found the charm of the music.Behind each song contains a story,I can not help playing the piano but want to understand the implication of its secret.
I m happy when ,I m playing the piano,Feeling very relaxed.I also like listening to pop music,I think they are great,warm and fast songs and feeling the slow songs' tenderness.
I have to cram in extra-curricular,in which I learned a lot of knowledge,but also make friends.
My extra curricular life is full and happy,although a bit busy,but rewarding.
One cannot make an omelet without breaking eggs.
顺便说一句.你这文章主题不明确.开头说跟主题没有太大关联,并且内容也不着边.
