Students Grading of Their Teachers
Nowadays, a lot of schools ask their students to contribute to grading their teachers. As a teacher, it is their responsibility to satisfy their students in all aspects. Meanwhile, it is admirable that school teachers prefer to expose themselves to their students.
If the system of grading of teachers by students is introduced, it will benefit students, teachers and the administration of the school for a number of reasons. For one thing, the system will give teachers and the administration of the school an insight into the minds of the students and show whether the teachers are successful in getting their lessons understood by the students; for another, it will also encourage the good teachers to continue their efforts and motivate themselves. What is more, it will expose those who are not doing enough and will lead them to correct their teaching methods as well as their attitude towards students. Thus the quality of teaching will certainly improve.
In a word, it is a promising concept and will bring surprisingly good results if applied with the right conditions.
【习作点评】
作者观点明确，赞成学生给老师打分。作为老师，就要做一个让学生满意的老师。这样，不仅对学生、学校有利，而且对老师本人也有利。这样，老师就会从另一个角度重新审视自己，看自己是否是一个成功的老师。如果得到学生的认可，这将是对自己的一次鼓励，为继续前行增添动力。如果学生的认可度不高，老师就应进行反思，调控教学方法和教学态度。这样，教学质量肯定会提高。作
者用简洁、明快的语言以及自己的经历列举了充分的论据，内容充实，贴近生活。For one thing, for another, what is more, in a word等过渡词的使用，是短文结构清晰，层次分明。最后，最值得一提的是，文中多次正确运用的高级词汇和复杂句式，给文章增添了不少文采。综上所述，这是一篇不可多得的佳作，值得向大家推荐。
二、写作模板
此模板适用于社会现象类议论文。参考模式如下：
Nowadays, there exists an increasingly serious social/economic/environmental There are a couple of reasons behind this problem/phenomenon. For one ；Based on the above discussions, I can easily forecast that more and more people
Nowadays, there exists a common phenomenon—with the development of the Internet, more and more people tend to send electronic cards instead of paper ones to their friends and relatives when an important holiday comes.
There are a couple of reasons behind this phenomenon. For one thing, compared with the traditional cards, electronic cards are more lively and interesting. They can give not only pictures but also sound and animation. For another, there are many websites online which offer varieties of cards for you to choose from. What is more, with the popularity of the electronic cards, less paper is used in making paper cards, which does good to our environment.
Based on the above discussions, I can easily forecast that sending greetings by using electronic cards will be accepted by more and more people, not only the young ones.
三、写作指导
写作思路是先列出一个具体的社会问题或者现象，然后分析产生的原因和产生的影响，最后提出解决问题的办法，或者得出结论，或者提出个人看法，或者预测前景。
论点、论据、论证是议论文的三要素。论点是作者对所议论问题所持有的见解和主张，论据是用来证明论点的事实和道理的根据；论证是用论据来证明论点的方法和过程。一般来说，议论文每段都有主题句来确定论点。论证的方法很多，但最常用的是因果分析法。即：分析事实与论点的因果关系，指出取得结果的原因是所要证明的论点，从而达到论证的目的。
在近几年的高考中，议论文的比重占得越来越多，议论文的.出题形式可以多种多样，有看图写作、图表、表格、书信等各种类型，但文体实际是议论文，而有时是夹叙的议论文。议论文的写作要点是：
1. 观点鲜明，文章一定有一个明确的中心论点。
2. 层次分明，一个中心论点通常有几个分论点支持，不同层次之间要分明，过渡清晰自然。
3. 最后一段一般要总结全文，得出一个符合逻辑的结论，突出中心思想。
4. 一般采用一般现在时。
5. 语言简洁有力，一般不采用口语。

1.【练习题目】
2010年上海世界博览会期间，上万的青年志愿者参加志愿工作，请你谈谈对此现象的看法。
【参考范文】
During the period of holding the 2010 World Expo in Shanghai, tens of thousands of young citizens are participating in volunteer work, hoping to devote themselves to the grand occasion. As far as I am concerned, everyone ought to enter for it. Here are the reasons I want to mention.
It can be argued that the advantages of doing unpaid volunteer work are enormous, because volunteer work is actually a two-way street. First of all, volunteer work should always benefit people who need help. Those who need help will feel happier due to our immediate help. On the other hand, as far as the young people ourselves are concerned, we have more opportunities to develop the sense of responsibility, independence as well as interpersonal skills in the process of helping others.
Through this kind of work, we become confident and mature. In addition, we can make many friends and increase our chances of getting the jobs of our dreams. Furthermore, volunteer work plays an active role in building up a harmonious society.
In a word, it is of great value for the young adults to offer volunteer work. The youth volunteers do make a difference by the voluntary work! Why not join them and do something for our country?

Second, it is a waste of money to smoke cigarettes. Smoking can cost a great deal of money. Once you are addicted to it, it is difficult to give it up.

4.【练习题目】随着经济和社会的发展，道路上的私人小汽车越来越多。请根据自己的观察和理解，谈谈自己的观点。
【参考范文】
With the fantastic development both in economy and in society in China, the number of people who own private cars is on the rise. Some people have bought cars of their own, and others are planning to buy cars. But I strongly object to the increase in developing private cars.
I hold that automobiles will give rise to a series of problems. In the first place, as more and more cars are produced and run on the road, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people. Next, private cars contribute to traffic jams so greatly that the advantages gained in comfort and freedom are often cancelled out by the frustration caused by traffic jams. The last problem is the increasing number of car accidents that have killed and will kill a lot of people in a friction of a second.
In a word, although automobiles have been playing a vital part in the daily activities of our society, they also bring us numerous troubles such as more serious environmental pollution, more traffic accidents and more energy consumption. They drink up huge amounts of fuel and throw out huge amounts of pollutants. Jams waste our precious time. Therefore, I am against developing private cars.

引出问题：如何处理工厂(甲对居民(乙的烟尘污染问题?庇古，《福利经济学》：赔偿、征税或责令工厂迁出。科斯认为这些办法并不合适，这类问题有待分析。
社会热点类作文400字【六】
假期的心情特别好，今天吃过早餐，哼着歌，随着轻快的拍子，走到阳台的摇椅上看起了新闻。
我看到其中的一侧新闻是这样说的：有一个人假期带着年老的母亲去看冰灯，开心地给老母亲拍照片，拍完了，在那检查是否照片虚了时，老母亲要下台阶，她对身边的女孩说：“闺女，能搭把手给我扶着你下这个台阶吗？”女孩伸出胳膊支持老母亲下那个台阶。老母亲谢过后，身后马上传来了女孩的妈妈教育女孩的声音：“老人要是摔倒，我们家就赔惨了。”
看完了这侧新闻我心都寒了，一个个字硬生生地敲着我的好心情。要知道我们中华传统文化就是尊老爱幼，要是没有人帮助老人，就连扶一下老人也怕成那个样子，怕要承担责任，我们现在谁也不敢扶，以后谁还会扶我们呢？
想了一天，我也想不明白，难道一个老人也扶不起吗？正是：爱吾爱，以及人之爱；老吾老，以及人之老；幼吾幼，以及人之幼。
