表格说明。即在说明事物或知识时,把与之有关的数字列成表格,插于说明文字之中。表中所列项目,根据说明需要而定。这样说明,既清晰集中,又能进行比较,便于理解和记忆。例如《万紫千红的花》这篇说明文第七自然节,在说明花的颜色时,就列出了表格:
这个表格里的项目有花的颜色和种数两类,共有9种花色,从而形成比较,有力地说明了花色之中白色最多黑色最少的`特点,将被说明的对象介绍得一清 二楚。至于花的姿态,花的开放时间以及花呈不同色彩的原因,表中均末列项,这就既紧扣了课题万紫千红,又突出了说明的重点。
插图说明。有些事物须用图示才能说得清楚,如某种新产品的介绍,某种科学知识的解说,某种复杂的事物的说明等,就常常在文学中配上插图或示意 图,以助文字说明。例如《统筹方法》,在介绍统筹方法时,就先后列举了三个示意图,一是相互关系箭头图,二是工作合并图,三是数字表示任务图,分别如下:
这三幅示意图,形象地再现了统筹方法的主要内容,通过图示不难看出,关系清楚,顺序明了,谁优谁劣不言而喻,从而使这种复杂的科学方法简单化了,给人以鲜明直观的深刻印象,是语言文字所无法比拟的。
运用图表助示法说明事物,表格的项目不可设计过繁,将可比的几个事物或几种知识的主要比项列出即可。图表应放在文中与被说明文字密切相关之处。 图表虽是全文的有机组成部分,但不可过多运用,它只是为文字服务的,起助说作用,图表一多,令人眼花缭乱,容易给人以厌烦和累赘之感。
在家乡 My Hometown’>我的.家乡有一个小湖,那是我最喜欢的地方之一。我总是和我的朋友一起去湖边,我们经常游泳、玩耍。有时我们会去划船,享受安静的时刻。现在的湖因为污染已经不那么干净了。我意识到保护环境的重要性。
Emerging from the cartoon is an eye-catching scene that the parents are willing to have a second child, while their only child do not agree because of his worry that he doesn't want to have another child, even his own sibling, share toys with him. Simple as it is, the symbolic meaning revealed is profound and thought-provoking.
We are supposed to place our attention on, instead of its funny appearance, the implied meaning of the cartoon: as the overall second-child policy expands throughout China, some only children are so selfish that they cannot accept the second child in their family. What can account for this undesirable situation? For one thing, they, as the only child at home all the time, have no awareness of sharing what they like with others due to the fact that all the family members give their love to the only child. As a result, when faced with the problem of whether they are willing to have a sibling, their first response is to refuse it. For another reason, some couples are eager to have a second child as soon as possible, which makes them neglect to communicate with their only child to let them realize the advantage of having a sibling companion in their childhood.
From what has been discussed above, it's safe for me to conclude that it is urgent to take some immediate and effective measures. What I recommend is that parents should let child know the importance of sharing with others, which is beneficial for them in future life. In addition, it's better for parents to have more communication with their only child once they want to have a second child.
To Whom It May Concern,
I am a student in this university who regularly comes to the library to spend my spare time. Generally speaking, the services you offer here is quite good; however, I have some suggestions for you to adopt.
To begin with, will you please prolong the time for reading? In the daytime, most of the students are having class, so they can’t come to the library. Moreover, some of the books on shelves are out of date. If you are so kind as to provide us some books such as the latest magazines, we will be greatly honored.
I really wish to have a more comfortable library. I would like to extend my greatest appreciation if you are so kind to take my suggestions into consideration. /Thank you for your time and consideration.
Sincerely yours,
Li Ming

Dear Friends,
On behalf of the Students’ Union of Beijing Foreign Studies University, I would like to extend our heartfelt welcome to all of the overseas students from all over the world to study in our university.
It is my great pleasure to propose several practical suggestions to you. In the first place, life in this prestigious university perhaps is not as satisfactory as what you expected. You may be tightly bound by continual classes, excessive homework and exams. In the second place, in spite of all these adversities, you will still enjoy your life in this esteemed institution. All types of extracurricular activities such as sports meets, speech contests, different social gatherings and dancing parties provide ample opportunities to make friends.
All in all, although there are a host of pressure, life in our campus is a worthwhile period in your whole lifetime. Wish you enjoy your life here!
Yours sincerely,
