各位尊敬的评委老师：
大家早上/下午好!
我叫**，是**大学环境科学专业的应届毕业生。
今天能在这里参加教师资格试讲面试，有机会向各位评委老师请教学习，我感到十分的荣幸，我从小就对老师万分的钦佩，梦想长大后能够成为一名合格的人名教师，但我深知要成为一名合格的人民教师不仅要有丰富的知识，还要有出众的能力，为了完成自己的理想，我严格要求自己，并努力学习，以期待着将来可以走上这三尺讲台。
可遗憾的是在2012年的\'高考中，我并没有顺利的考上师范大学，那时的我很失落很迷茫，一心渴望当老师的梦想就这样破灭了，进入大学后在大学的学习生活中我了解到可以报考教师资格证，得知这一消息让我兴奋不已，内心想成为一名教师的梦想再次被点亮，我又找回了奋斗目标，并为之努力拼搏!
试讲的科目各有特色，我却独爱生物，因为生物学(Biology是一门研究生命系统各个层次的种类、结构、功能、行为、发育和起源进化以及生物与周围环境的关系等的科学。它是农学、林学、医学和环境科学的基础。它是21世纪的主导科目。社会的发展，人类文明的进步，个人生活质量的提高，都要靠生物学的发展和应用。对人类来说，生物太重要了，人们的生活处处离不开生物。
所以我想成为一名生物老师，与学生一同学习，为学生解惑答疑。今天站在这里，恳请给位考官能够给我一次成为教师的机会，或许我不是最优秀的，但是我知道经过磨练，我一定是最有潜力的，如果我能有幸成为一名人民教师，我将全力以赴，以自己的爱心，热心和敬业之心去实现我儿时的梦想，我将用我的激情，热情和感恩之情去延续今生的奋斗目标!
我的介绍完毕。谢谢!

胞间 连丝：是连接相邻两个植物细胞的跨细胞的细胞器，是植物细胞间物质和信息交流的直接通道，行使水分、营养物质、小信号分子以及大分子的胞间运输功能。
初生纹孔场：初生壁的厚度往往是不均匀的，常有一些凹陷区域，其内有许多胞间连丝通过，这个区域称为初生纹孔场。
纹 孔：次生壁形成时，往往在原有的初生纹孔场处不形成次生壁，这种只有中层和初生壁隔，而没有次生壁的较薄的区域为纹孔。

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

生物课是我在小学没有接触过的科目，生物老师把生物课的内容讲的既新鲜又生动，让我对生物产生的好奇心。
生物老师首先讲了生物的定义，（有生命现象的物体）及生物的特征（进行呼吸，获得氧气，排出二氧化碳，需要营养生存和繁殖，生物对外界刺激反应，应刺激，排废物，新陈代谢）
生物老师滔滔不绝生动的课堂给我带来对生物界的惊喜，物种种类大约有200万种，其中，植物40万种，动物150万种，地球真是个大家庭。
应刺激特征，以含羞草为例，含羞草身上有一个液体袋囊，袋囊里充满了液体，当有在界碰触它的叶子时，叶子就会合拢，这一现象，叫应刺激特征。
还有一种非生物类型，以珊瑚为例，珊瑚是有珊瑚虫一代代死去的外壳经年深日久的堆积在一起，慢慢形成了千资百态的珊瑚，珊瑚的聚多形成了珊瑚礁，珊瑚礁是珊瑚虫和藻类植物生活场地，藻类植物给珊瑚虫提供了氧气，珊瑚堆积的越高，附在珊瑚的藻类植物所的到的阳光和氧气越充足，藻类就越茂盛，这就说明珊瑚喜欢生活在温暖的浅水区，和藻类植物互为利用。
神奇的大自然里创造出形形色色的生物，它们的奥妙等待我们去探索，去解答。
