the diversity of my university life
Look! There is a rainbow! On the first day of my university life, when I walked into the campus, there was a rainbow bridging over the fountain, I hadn’t seen rainbow for a long time. I was so excited, and leaped high with joy. My ponytail danced with my happiness. It was a propitious sign indicated that my life in university would be colorful, and actually it is!
After my entry into university, I found my life so busy. What I should do is not only gaining the scholarship but also being a good monitor and leader of shanghai university percussion band. I got the 1st and 2nd price of scholarship in my 2 years of study. I organized charity donations for schoolmates with financial difficulty or disease. Every week, I give drum lesson to new members of our percussion band. And there are always a lot of non-business performances, such as entertaining guests, celebrating party, cultural exchange with foreign students delegations and their bands. Of course, part-time job is indispensable in my vacations. I ask for no payment but aim at getting accustomed to the society.
Sometimes, my friends advise me not to tire myself out with such a tight schele. I wake up before the rooster crow, and continue working till very late when others are enjoying their sweet dreams. Every time I come back from the rehearsal of percussion band, I have to finish my homework with the help of my own charged light because of the blackout in out dormitory. Ma ...
㈡ 关于医学史上重大的突破的英语作文
五项能改变医学史的生物科技重大突破
据美国大众机械杂志报道，随着科学技术的日新月益，近年来生物医学技术也得到快速发展，比如：从唾液可检测出癌症，打一针即能沿着身体脊髓生长出新的神经组织等。目前这些世界上最新的生物医学技术已模糊了生物学和科学技术之间的界线，它们共同的目标是帮助恢复、提高人类的生活质量，以及延长人类的寿命。
1、抗腐微生物细菌
生存在牙齿上的细菌能够将糖转化为乳酸，而乳酸可以腐蚀牙釉质导致牙齿被蛀坏腐蚀。位于美国佛罗里达州的ONI BioPharma公司最新研制一种新型菌株，叫做“SMaRT”。它不会产生乳酸，却会释放出一抗菌素，可以杀死这些自然导致腐蚀的细菌。牙医只需在牙齿上涂上一层SmaRT，即能实现避免牙齿被蛀蚀。目前在临床测试阶段，牙齿涂抹这种抗腐微生物细菌后便能够永远保持健康。
2、人造淋巴结
来自日本RIKEN研究院的科学家已成功研制出人造淋巴结，它可以生成免疫细胞用于对抗感染，虽然人造淋巴结有朝一日可以代替患病淋巴结，但目前人造淋巴结只能当成特意定制的免疫促进剂。医师用特殊的细胞填充淋巴结能够很好地治疗某些疾病，比如：癌症和艾滋病。
3、哮喘传感器
据统计，哮喘病患者占美国急诊患者的四分之一，但目前由美国匹兹堡大学科学家最新研制的一种哮喘传感器能够将哮喘就治人群数量直线下降。该传感器是一个手持型设备，外层是涂有一层聚合物的碳纳米管，该纳米管比人体头发直径还要细10万倍。它能够在短短1分钟内直接分析出人体呼出的一氧化氮气体数量，据悉，一氧化氮气体是哮喘发作之前在肺部形成的一种气体。
4、唾液即能检测出癌症
之前医生所采用的活组织检查已过时，目前由美国加利福尼亚州大学洛杉矶分校的研究人员最新设计一种检测装置，仅需要提取患者的唾液样本即能探测出该患者是否患有癌症，十分便捷有效。与癌细胞相关的蛋白质能够对这种检测装置的色样产生响应，一旦该装置发现有癌细胞存在，便释放出荧光线，可用显微镜进行探测到。加利福尼亚州大学洛杉矶分校工程师Chih-Ming Ho强调称，我们可以使用类似的方法，通过唾液便能对多种疾病进行有效诊断分析。
5、生物起搏器
电子起搏器能够挽救人的生命，但是长期使用电子起搏器会导致其硬件磨损最终使该仪器无法使用。目前，多家大学的研究人员正在致力研制一种不需要电池的起搏器，这种生物起搏器注入心脏受损区域，可实现在干细胞中基因表达。该起搏器能够更好地适应患者的生理状况。经过实验这种生物起搏器能够减缓实验狗的心脏跳动速率，直至达到正常跳动速率，而且并不出现任何并发症现象。
㈢ 关于对转基因食物的优点和缺点及自己看法的英语作文
这就是关于转基因食品优缺点的作文：Genetically modified food is science brings us the proct, now of cultivated land area of less, genetically modified food will play more and more important role, if the use of transgenic technology can solve the world food shortage problem, it is not quite good? Genetically modified food in the world now is a kind of new things, new things, people need time to promote its accept also need some time, we cannot put new things in the cradle, a stick to it from the beginning, that cannot be eaten of genetically modified food. You think we don't of hybrid rice is a genetically modified food? But we can open it from? And if they can pass the soybeans genetically modified technique using atmospheric nitrogen inside his proces fertilizers to other crops gene transfer in the mankind, it is. Everything is both sides, especially technology, science and technology is a double-edged sword? Genetically modified food has its disadvantages, like some worry, because it will not change, will destroy genetic evolution, etc. Genetically modified food and nutrition inside it isn't like that, the propaganda of people worry is understandable, after accepting a new things take time. But we also should see the benefits of them, I think as time slowly past, genetically modified foods will be accepted by people. 希望会对你有帮助吧，谢谢！
