初一生物励志作文【二】

Dear Sir or Madam:

In my capacity as the chairman of Biochemistry and Molecular Biology Department, the School of Life Science, Nankai University, I deem it a pleasure to recommend Mr. Bruce Liu as a worthy candidate for graduate studies at the Department of Cell and Molecular Biology of your esteemed university.

Over the past four years, I delivered two important courses Genetics and Cell Engineering to the Mr. Liu‘s class and his performance was impressive. He is endowed with a strong curiosity in the quest for new knowledge. Before attending each class, he would make full preparations so that he could quickly assimilate what was being taught. Sometimes he could come up with some surprisingly thought-provocative questions and he had a habit of discussing important problems with me in great detail. During those discussions, he often brought with him valuable materials that he obtained from a large quantity of technical literature. Such an initiative enabled him to broaden his ken of knowledge extensively and to cultivate and significantly improve his ability in reading technical literature in English and to follow the latest scientific and technological development in the world. Therefore, even before he graduated, he had already distinguished himself from the rest of his classmates in his English proficiency. Furthermore, his indefatigable spirit of reading large amount of technical materials was not simply intended to secure high scores in his coursework, but more importantly, to satisfy his almost insatiable interest in biology.

Apart from this, I was also very impressed by Mr. Liu‘s hands-on ability in conducting experiments. For many complicated experiments, he undertook them with a rigorous and conscientious attitude and would always complete them satisfactorily. In dealing with crucial steps involved in the experiments, he tended to make bold hypotheses and conduct substantial observations, ultimately achieving remarkable results. All those testify to Mr. Liu‘s tremendous potential in academic research, especially in his analytical skills and in the execution of experimental procedures.

In addition to his scholastic aptitudes, Mr. Liu can be described as trustworthy in personality. His kind-hearted nature and his integrity have created many friends for him. By no means a bookworm, Mr. Liu took an active part in extracurricular activities in which he enhanced his group spirit and the sense of collectivism. His willingness to assist his classmates has brought him a very high reputation.

To summarize, Mr. Liu has been an outstanding student in our department and he is fully qualified to undertake high-level studies in a more challenging environment. His excellent qualities will undoubtedly facilitate him in achieving satisfactory results in his future academic pursuit and in his career.

Yours Sincerely

Professor and Chairman of Biochemistry and Molecular Biology Department

Nankai University

初一生物励志作文【六】

学习生物的感触自打初一开始,我们便有了生物这门课程,直到初二的学习,我对他有了很深的情感,我也产生了许多的感触。

生物学系非常奇妙的学科,他介绍了万物的发展和规律,尤其我喜欢“自然界的动物”这一节,他为我们介绍了自然界各种各样的动物,让我感受到了动物的丰富性与多样性,富有趣味!比如生物书中我最喜欢的一个问题:为什么大鯢叫做娃娃鱼呢?原因很简单,因为他在叫的时候声音很像娃娃在哭泣时发出来的,所以把它叫做娃娃鱼,这是多么有趣的自然现象啊!

在上学期的课本中,我们学习了人的人体,这一节让我感受到了人体内部的精密,这是机器人,是现代机器人无法比拟的,同时,这也是现代机器人将要进步的方向和发展的前景。有一个问题是这样问的:为什么手上有这么多的褶皱呢?原因是因为在远古时期,人类需要打磨器具,所以弄了这些褶皱,才使我们有了摩擦力,更好的来生产和工作。更令我惊奇的是,如果把一个人的小肠平铺开来,它的表面积,也将会有一个足球场那么大!

生物是自然界中的最有趣的一门学科,它教我懂得自然现象的神奇,以及我们生活生态圈的生物的多样性。
