Peachey again had done a great correction job.  It would be a waste of time to correct you in a similar manner.  I shall correct it in a different manner so that you can compare different styles.  There are more than one way to express the same thing.

Don't use all these rubbish smileys in your formal essay.  No one is going to take you serious if you do so.  A lesson to be learnt before you become a boss of your company.

1.  Your use of the word, "emulate" is wrong.  Emulate means to copy, follow  or imitate someone who is better than you.  The correct word is "emulous".  My emulous heart can mean a heart with eagerness or ambition to equal or to surpass another or characterized or prompted by a spirit of rivalry. I prefer simpler but equivalent words that offer the same meaning.

Hi, friends！I am a Chinese girl. I hope I can become a translators in the future, and I will start up a translation company. Sometimes I hardly learning English, and sometimes I give it up. I always think I am so young that I have plenty of time to learn it. Maybe, my emulative(what do you mean??) heart is strong; in middle school my English is not better one (I was). (again, I don't understand what you mean) Dear pen pal, please give me encouragement and let me have some power to learn it well！(+﹏+)~

Good effort. One suggestion I have to make is to stop using the punctuation from the Chinese keyboard, (eg. ，。) because English punctuation functions slightly differently. I can see you making a pile of mistakes if you continue using Chinese punctuation.
