这就是我。

第一，对不起，我的中文不好。我刚学了六个月的中文。
我叫Sarah, 中文名字叫莉莉。今年秋天我会去加州理工学院。主修物理，副修中文。我很高兴，但是我也有一点紧张。因为，我家离加洲很远。
我家有四口人。妈妈，爸爸，妹妹，和我。我妈妈是美国人，我爸爸是加拿大人（他从加拿大来美国上大学。）我妹妹是从长沙领养的（她一岁到我家，所以她不会说中文。）
我是基督徒。我非常喜欢音乐（如：唱歌，弹琴，打木琴， 我最喜欢的是听音乐。）我也喜欢长跑。
如果你想学英文，我很高兴跟你一起Skype。

我想学英文，练口语。

A cover letter for postdoctoral job

      I am writing to apply for the postdoctoral position advertised on the website of the scholarship-positions.
      My experience and enthusiasm makes me an excellent candidate for the position you are seeking to fill. My 5 years experiences in our institute allowed me to develop several professional skills, such as composites molding technology, 3D weaving technology and mechanical property testing. And I skilled in using the software of ANSYS, CATIA, LabVIEW, AutoCAD, ect. I also have the knowledge of automatic control, for I have made an automatic molding machine used to produce composite z-pins. The machine has been applied for a patent. In addition, I have leaded other 4 students to participate the 3rd SAMPE China super lightweight composite wing contest sponsored by Boeing Co.. We achieved very good results in each of the item in the contest. We got the 1st prize for the appearance quality, the 2nd for the mechanical property and 1st for the poster.
        I am confident that I can perform the job effectively. I am a quick learner who pays attention to detail, and I am also highly motivated. Thank you for your consideration. I look forward to the opportunity of meeting you.
