化学品危险性标志:英语高手帮忙检查一下，这篇短文的错误！谢谢；啊

I am the graduate student(一般指研究生） of JIUJIANG（不用全部大写） university, majoring in an advertisement（广告专业不能这样说。楼上的“十三级”也跟着你犯错了） to learn profession（也不对）, can use PS etc. software masterly.The time in school, once held the post of a leader of class, and made use of summer vacation for period, to the advertising agency practice of Tienjin, everyone's impressions to me are all very good（这儿问题很多.....).
同时(这个“同时”汉语可能说的过去，翻译就没必要了），我的性格很外向，开朗(外向、开朗是一个意思，前者包含后者。这儿加点其他的，比如“正直、幽默等之类的更合适）！我喜欢与人交流，去过很多地方旅游，这次也是因为喜欢这个城市所以才来到这里找工作。
In the meantime, my personality is extroversive（全部都是日常词汇，突然冒一个“大词”出来吓人，不好！）, bright!I like to communicate with person, having been to a lot of place tours, is also because of liking this city this time so just arrive at to seek a work here（问题较多！）.

I am a graduate from Jiujiang University, majoring in advertisement. I am proficient in such softwares as MS Office and PS. During my university years, I once acted as the class representative and I worked part-time during the summer vocation in an advertising agency in Tianjin.

As a kindhearted，outgoing， and honest young man, I enjoy communicating with other people. I have travelled widely. Now I am in this city to find job opportunities because I like this city.
