一篇英语作文介绍一项发明【一】
在世界上有一种和人最亲近的文具，那就是“笔”。学生常用铅笔、原子笔、萤光笔；老师常用的`粉笔、白板笔等，走进文具店，就看到琳琅满目，五花八门，五彩缤纷，各式各样的笔。
我最常用的笔是：自动铅笔，原子笔，萤光笔。自动铅笔的笔芯是用石墨磨成粉和黏土製成的，然后再用木头包起来；而原子笔是用一支有颜色的笔管再用一个塑胶的外壳组合而成的。
记得有一次，我上课回答老师的问题，因此老师送我一支笔当奖赏，那时，心情真是乐不可支啊！那支笔是我的宝贝，也是一只幸运笔，每当考试前，我都告诉它：“要加油喔！今天就靠你让我我的好成绩了！”许愿完后就开始如行云流水般，快如闪电般，以飞快的速度将考卷写完了，真是一只幸运笔啊！
笔在生活中，是人类不可或缺的好朋友，文具，它带给我们便利。如果没有它，我们可能就要用绳结记事或是把字刻在石头上来沟通了，笔，真是人类伟大的发明啊！

一篇英语作文介绍一项发明【三】
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
