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。
四、巩固练习
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?
2.【练习题目】
某些中学生为了显示自己成熟或表明自己醋而吸烟。请写一篇120词左右的短文,列举吸烟的危害,并提出建议。
【参考范文】
I am sorry to know that more and more middle school students begin to smoke. I think it is wrong to believe that smoking is cool and even think that smoking makes you appear to be mature. In fact, smoking is not cool but very dangerous.
First, smoking can do much damage to health. Scientific researches show that smoking can lead to heart diseases, cancers and other problems. It is reported that about 5 million people die of diseases related to smoking each year all over the world.
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.
What’s more, smoking can cause fires easily, which may do great damage to your life and your surroundings.
So give up smoking at once! Only in this way can you keep healthy forever.

【参考范文】
In recent years, studying abroad has been popular. Tens of thousands of Chinese middle school students have gone to foreign countries to study.Many people are trying their best to apply to go abroad.

Therefore, it is advisable to attend schools abroad.
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.
生物体的每一个细胞都包含着复制自身的全部信息,只是 除精卵细胞外的其他细胞中这些信息大都被关闭,这些细 胞都被特别化了,只能分裂成肝细胞、肾细胞或皮细胞等 。不过,一但这些信息被激发,任何一个细胞都能复制出 一个完整的个体,由於它的基因信息不变,它可不失真的 复制出原来的个体。1997年 2月23日,英国爱丁堡的罗斯 林研究所宣布了复制羊“波莉”的诞生。他们从一只雄性 绵羊身上抽取了乳腺细胞,将细胞核用显微手术植入一个 已用电击法除核的空卵泡内。在卵子环境中,该细胞核中 的遗传信习被唤醒,分裂成胚胎,再植入另一只母羊的子 宫,产出与原雄羊完全一样的复制体。主持该项研究的科 学家维尔穆特声称,如果去做的话,两年内可以培育出第 一个复制人。目前的复制技术,它需要卵细胞的环境来唤 醒细胞核,细胞核分裂成胚胎任需植入母体的子宫。但人 们早已认识到这些绝不是不可逾越的障碍。一但复制人降 临这个世界,必将引起数不清的道德法律问题,人类的独 特性、神秘性,人类对自身生命的敬畏及宗教的信仰,将 澈底瓦解。 8.DNA的生命 另一个值得探讨的生命保存问题,就是电影《侏罗纪公园》中秘密的时空胶囊,故事虽是虚构,但并非是信口开河 。已经在地面消失的古生物,能够使它们在现代复活,这 并不是痴人说梦,现在愈来愈有可能实现这个梦想,其中 的关键就是封闭在琥珀中的化石,琥珀是松树等植物的树 脂所变成的化石。其中有些会含有昆虫等小生物,并保有 完好形态。科学家打算从这些生物取出DNA〔去氧核糖 核酸〕,DNA被称为生命的设计图,若能取得古代生物 的DNA,便有可能藉由日益发展的基因工程与生物科技 ,在不久的将来使它们再度复活。
“追星”如今已成为一种时尚,成为年轻人的标志。其实“追星”并不是一种好现象,但如果适当的,选择好的“星”做为自己学习的榜样,这也不失为一件好事。但许多人却以夸张、疯狂的态度“追星”,不仅没有好处而且对社会也无益。
那些“明星”和我们一样,也是人,不是神。有些人疯狂到为了得到他们的东西,不惜一切代价。记得电视上报道过,有四个女生太喜欢自己的偶像,但却怕对他不够忠诚、热心,并决定要将那偶像永远留在她们“心中”,便活生生地吞掉了那偶像的照片。那样有什么用?这样就在“心中”了吗?到头来还不是一个个的被推进手术室!那照片有用吗?这样疯狂地崇拜有意义吗?有的甚至为了偶像而要轻生自己。这种做法实在太恐怖了,扰乱了社会秩序,增加了家人的负担。这样子追星到头来还不是一场空。
正因为那些Fans的太过热情,使那些原本和我们一样是工作者的“星”渐渐忘却了自己真正的价值。但有一件事情让我难以忘却。
一次,一个电影明星来到汽车检修站,一位女工接待了他,可那位女工却对他的到来没有任何惊讶和兴奋,这便引起了这位影星的注意,其实那位女工很喜欢他,也爱看他的电影但她却没有像别人那样疯狂、热情。她说:“您有您的成就,我有我的工作,您来修车就是我的顾客,我会热情的招待您,如果您不是明星了,再来修车,我还是一样热情的`招待您。”最后她说了一句发人深省的话:“人与人之间不应该是这样吗?”是啊!这就是明星的价值,真正的价值。他们就和我们一样,为什么我们要放弃掉自己所有的,去盲目的崇拜呢?
可是既然社会上有了“追星”这一现象,所以我们也可以适当的“追星”,选择品德好,有益于我们自己的人作为自己的榜样。其实“追星”有好有坏,但好与坏就在于我们自己的选择了。
像“追星”这一现象的流行,我们需要独立思考,了解它们所具有的意义所包含的价值,避免盲目效仿追随。
不久前爆发的“韩白骂战”闹得沸沸扬扬,在这里,我不谈事件根源,也不论孰是孰非。我不懂文学,当然也就不会争论什么文学不文学的,(这事儿恐怕不是文学争论那么简单咯)只说说从中看到的几个社会现象。
地球就像一个大温室,培育了千万种的动植物,依赖着大 气层的保护,内有充足的日光、空气、水及适宜的气候, 不断的适应各种环境而繁绵生长。如果离开这个温室,这 些生物还能生存吗?一般人总认为,离开地球在太空中或 月亮上,压力极低、温差又大,几乎没有空气与水份,而 且还充满各种宇宙线,在这种环境之下,应该没有任何生 物能够生存,而事实确证明我们错了! 其实在恶劣的环境中地球生物还能生存,这在地球上一些特殊而不适合生物 生存的环境中,却也常发现一些能适应的生物。例如在释出强烈辐射线的原子炉内,也可以发现有微生物。1977年 法国科学家在太平洋3000米深处,在水温高达 250度的热 泉口,发现红鱼、螃蟹、白蛤类等数种生物。而在南极极 冷的冰块中,也可以发现嗜寒菌。由此可见生命力是非常 的顽强,在各种恶劣环境之下,仍有能适应的生物。这给 我们很重要的启示,我们不能以狭隘的角度来观察所有的生命现象。
