Dear Family,
You must be greatly surprised when you get this letter, not from anyone else but from your dearest son, since I have never written a letter for ages in such a traditional way. The purpose of my writing is not so much to express my gratitude for bringing me up, as it is to tell you something about my college life.
It has been more than two years since I started my college life and I have adapted myself to the new environment here, even though at the very beginning, I was not quite used to it. My classmates are pretty friendly and they offer to help me whenever need be, which is really precious for me. My teachers tell me the differences between college life and high school life and give me some necessary advice on how to learn in college. Because of their kind-hearted help, I learn to know the importance of cooperation and communications between each other, especially when in Group work.
In the past several months, I have been busy preparing for TEM 4.Therefore, most of the time, I stayed at school and seldom kept in touch with you; I should have been ashamed of this. But now it is completely finished, and I will never do that again. In my spare time, I usually go to play basketball to keep fit since you always ask me to practice more to keep healthy. What is more, I like to go to the English Corner to practice my spoken English in order to improve my oral English level, which is of importance as English major.
Finally, I would like to specially thank you for providing me the best education and experience. Without your support and understanding, it wouldn't be the same. In regard to the future, I will make every effort to study for my degree and make the dreams I had envisioned come true.
Take good care of yourselves as you have asked me to.
Best regards,
Jay

1. 举例子:使文章更加具体,更有说服力,更客观的说明了事物。
2. 作比较:说明某些抽象的或者是人们比较陌生的事物,可以用具体的或者大家已经熟悉的事物和它比较,使读者通过比较得到具体而鲜明的印象。
3. 列数字:具体准确为说明对象服务。
1、时间顺序:有明确时间词。
2、空间顺序:上---下,左---右,前---后,一般适用于参观游览类或介绍事物类说明文。
3、逻辑顺序:现象---本质,主---次,远---近,简单---复杂,原因---结果。
1、说明文语言的根本要求是具体,科学性(内容),准确性(语言),简练明确;文学性说明文还要求生动性、形象性。
例:①“人口剧增,资源短缺,这是当今人类面临的最严重的环境问题之一。”
第①段中加点的词“之一”能否去掉?为什么?
答:不能去掉。因为当今人类面临的最严重的环境问题,除了人口剧增,资源短缺外,还有水质污染,大气污染等,所以使用了“之一”一词,就使表达更严密、更准确。
例:②、??目前,研制一颗大型卫星的.周期为10年左右,而一颗纳米卫星的研制仅仅需要两三年即可,这样更始应快速发展的科技时代。比较文中划线句和下面的改句,哪个句子更好?
原句:而一颗纳米卫星的研制仅仅需要两三年即可。
改句:而一颗纳米卫星的研制需要两三年即可。
答:原句好,因为原句中“仅仅”一词,更进一步强调了研制一颗纳米卫星的时间短。
答题步骤:1 能否删(能否换)
2 解释词意
3 代入文本
4 删去后的影响
5 总结(体现准确性,科学性等)
