大一新生么？其實高中的時候的性格完全可以在大一的時候就拋棄掉。我同樣是在大學(xué)開始學(xué)者讓自己大方起來。而且這不需要很多的篇幅，一般就是老師和同學(xué)之間一個了解的機會。建議：個人姓名，省份，愛好。Good morning/afternoon/evening, my name is XXX.（姓名你可以選擇你姓名的亮點進行介紹，給老師一個比較深的印象，比如你的姓名和哪個名人一樣）It is really a great honor to have this opportunity/chance to introduce myself.Generally speaking ,I am a hard working student especially do the thing I am interested in.（性格，你沒有必要說自己是一個內(nèi)向的人，自我介紹，就是為了和別人更好交流，說自己的優(yōu)點） I will try my best to finish it no matter how difficult it is. Furthermore,I am a person with great perserverence. during the days preparing for the colledge-entrance examination,I insist on running every day, no matter what the weather was like.and just owning to this,i could concentrate on my study and succeeded in the end.（這些你可以換成自己的情況，只是一個借鑒，至于有不會的英語，可以查閱字典或者可以補充提問）well ,in my spare time ,i like basketball, tennis and chinese chess. And English is my favorate subject.I often go to English corner to practise my oral English on every thursday,and write compositions to improve my witten ability .but I know my English is not good enough ,I will continue studying hard. （個人愛好）還可以加上一些諸如希望和大家友好相處，幫助別人之類的。然后就是結(jié)尾，這個是必須有的。Ok, that is all,thank you for your attention.希望能夠有所幫助。
