英语作文素材介绍一位科学家【一】
在一个五彩斑斓的世界里，有一位对未来充满憧憬少女……那就是我，一位在非常发达的世界里杰出的科学家。
随着生活水平的提高，越来越重视孩子们的学习。家长害怕孩子们不好好学习，就把所有的书本都放在了书包里。孩子们背上了这种负重的书包，给他们自身也带来了很多危害。例如，背负重的书包过久，会让孩子们骨骼变形，生长速度慢，发育不良等等。假如我是一位科学家，我会发明一种书包。这种书包可以缩小，也可以变回原来的样子。把书本放在这种书包里，按变小的按钮，书包会按10：1的形状变小，重量也变轻，非常适合携带。当用的时候再按变大按钮，书包和书本又回原貌了。这样学生不会担负超重的书包，得各种疾病。
我会发明一种橡皮一样大小的仪器。这个仪器通全世界的每个角落，当哪里要发生灾害时，它会提前一天发出预告。拿手指一按这个地区，仪器便通过电向每家每户告诉消息，仪器的速度最多5秒钟就可以告诉所住在这个地区的人。
人们觉得噪音太多，让人们难以清静。我会发明像铅笔一样大小的收集噪音器。这个收集噪音器从世界各地收集到这里，从铅笔的尾端进去，人们只会听到缩小10倍后的噪音。当收集100分贝的噪音时就从铅笔的前端出来一棵茂盛的树，这样树也会逐渐增多。这种树有一种功能：可以从海水中汲取盐水再通过树的根向人们提供水资源，在提供水时，只会吸取其中的一小部分。这种树的寿命长达好几百岁。
假如我真成一位科学家，我用我的全部人生来发明一切对人类有用的东西，在我和你们共同的努力下，明天一定比今天更美好、更繁荣、更发达！
英语作文素材介绍一位科学家【二】
Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University
