一种事物或现象（负面意义倾向）
关于A的话题,早已引起了广泛的社会关注。如今在电视、报纸、日常生活的很多角落，都有越来越多的关于A的议论。
给A一个精确恒定的定义并非易事，因为它的概念涉及了科学、人性、思想、经济、社会、自然等广阔的领域。一般而言，我们可以这样描述A…
A能成为公众关注的焦点，主要是由于它对个人、集体乃至整个世界都有着不容忽视的不良影响。
认真分析后我们可以看到，A对社会/世界 /健康的不利有很多。首先，从最直观的角度来看，A的出现直接损害了（这里加入一句针对性的话，如人类的身体健康和环境的平衡） 。（举例）。其次，从更深一层次上讲，它为人类的精神文明蒙上了一层阴影。更可怕的是，由于A所产生微小利益，却促成了许多可悲的人们为其忘乎所以，破坏了人类生存的法则和空间。
事实上，A的出现是社会发展和人类进步的产物，A所带来的危害是人类进化过程中付出的代价。同时，A的产生来源于部分人们的自私和趋利性，他们看到的是肤浅和片面的'利益，而从未从整个全局和人类整体的利益出发去认识和分析它。这使得A始终挥之不去。对此，我奉劝他们，跳出狭小的角落，用长远和全局的眼光去重新审视A。
而如今，我们已深受其害，要想消除它的危害，我们必须从根源上杜绝它的产生，我们每一个人都应给予A高度的重视，用系统的和科学的方法去解决，唯有这样，避免它带来更多损失，我们人类前进的脚步才会更加平稳，更加欢快的迈向辉煌的明天。

For example,you shouldn’t forget to wash your hands before meals.Besides,don’t spit everywhere and try to cover your mouth or nose with paper or hankerchiefs when you have to cough or sneeze.What’s more, remember to wear the mouth-cover if you have to go to the public places, such as the crowded cinemas,supermarkets, buses,where the A flu may spread easily.
Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
Last but not the least, if you are unlucky to be infected with the slight flu cold, try to stay at home,and take some medicine. Do pay attention to your daily body temperature. If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.
Only by doing like this can you prevent or defeat the A flu in the end.

当今社会，追星也成了一种时尚。;追星就像社会生活给青少年出的选择题，是随波逐流、人云亦云，还是独立思考、理性行动，需要我们找出正确答案。其实，追星不一定是坏事，它也有好的一面。明星们哪个没有坚强的意志?没有优点?主要还是在于我们如何抉择。明星们对我们是有积极的促进作用的，有的人会梦想着将来能成为明星，这就需要有件事的文化功底。更何况台上一分钟，台下十年功。明星的前提条件便是能吃苦耐劳、有坚强的意志。
看过这样一则故事：刚刚卸任的联合国秘书长安南，在庄园举办了一场慈善晚宴，旨在为非洲贫困儿童募捐，应邀者都是富商和名流。晚宴即将开始时，小露西来到庄园门口，她手里捧着瓷罐。抱歉!除了工作人员，没有请柬的人不能进去。保安说。叔叔，慈善不是钱是心，对吗？小露西问保安，保安愣住了。我知道收到邀请得人有很多钱，他们会拿出很多钱，我没有那么多，但这是我所有的钱，如果我真的.不能进去，请帮我把这个带进去吧!”说完，她把储蓄罐递给保安。巴菲特被她深深感动了，把她带进了庄园。当晚，巴菲特捐出了300万美元，比尔盖茨捐出800万美元，而仅捐出30美元25美分的小露西却成为了当晚的明星!显然，我们对明星的理解始终停留在华丽的外表、排场等方面。真正的明星，需要的更是一颗博爱之心，需要以自己的吸引力来感染其他人奉献出爱心。再如;壹基金的创始人李连杰，他说演戏是我的职业，而公益慈善是我终生的事业。我们真正应该崇拜的、追随的，应该是他们身上这种奉献精神，是他们无私的爱心。
追星不应该用盲目之类的词来形容，只是得自己把握好分寸，寻找到适当的目标。这样的追星才有意义、有价值，才是我们应推崇的!
英语4级作文如何解释现象【五】
Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先，提纯范文 “谋篇布局”及结构模板。
第一段：提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段：正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段：摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次，提纯范文“段落写作”。
段落写作分为统一性，连贯性和完整性三方面。
统一性(unity：段落开头的主题句应该做到不可太宽泛，也不可太具体，做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明，另一方面从坏的方面说明。
连贯性(coherence：关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰，层层展开。
完整性(completeness：以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头，这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次，提纯范文“句子写作”。
1. It has been shown that … …
类似句型：It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单，注意练习并接句的使用，会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as，如：
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头，句式简单，我们可以通过把since提前改变句式，如：
Since the boy was ill, he was absent. 句式多样化。
最后，提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法：millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论，辩论”的意思，而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.，相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略：使用最近所学的单词，如intellectual > intelligent > bright > clever
在分析并掌握范文之后，我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文，以供参考：
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.

分析范文或优秀作文是我们学好写作的第一步。不要小看任何的优秀小短文，那其中一定有需要你掌握的内容。To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界，
一花一天堂，
手中即无限，
永恒亦短暂。
英语4级作文如何解释现象【七】
生活中有很多的物理现象，许多简单的现象可以用所学知识去解答。
现象一：飞快的火车有一个安全距离，当我们在公路上步行时，不宜靠中太近，除了害怕离线的车会撞到之外。还有一个意料之外的`原因，对此本文将作出解答。
现象二：取两片很薄的纸，将他们贴近，用力的吹，我们并不能将纸吹开，反而出现被“吹拢”的情况。
现象三：对于相同流量的水而言，口径大的水龙头，水的流速很慢，但是对于口径小的水龙头，可以明显的看到流速加快了。这是什么原因呢？
总结来看，空气和水都是流体，在两者之间有着一定的共同点，都遵循流体的基本性质，在流体的学习中有两个很重要的方程叫：伯努利方程和连续性方程。用它们就可以很简单的解释上面三个现象。首先，伯努里方程的基本表达式为：P+1/2pv+pgh=恒量。P指流体周围的压强大小，p指流体本身的密度，v指流体的速度。在上述但现象中，可把水和空气近似的看作理想流体，且它们作常流动。在以上前两种情况中，都可以将pgh看作是不变的，所以我们很容易的就得到P+1/2pv=恒量。容易得出压强和速度成反相关。下面将对三个现象作出具体的解释。
解释现象一：其中提到一个意外的原因就是很有可能身边的空气将我们“推”向汽车而发生意外。为什么这么说？当车飞快的从我们身边开过的时候，对周围的空气造成了影响：使它们的速度加快，在这样的情况下，根据上面的推倒易知：速度过快造成周围空气的压强减小，在汽车周围形成一个压强差，在车周围的事物就容易被“压”到车下。这是相当危险的，所以步行要尽量的靠边走。
解释现象二：当两片薄纸靠近，我们将它们看成和外面的空气分开，当我们吹气时，使得两纸间少量的空气流速加大，压强减小，外围的空气使得纸片贴在一起。
解释现象三：同流量即体积相同，所以易知SV=S V。这就是理想流体的连续性方程。它表示理想流体作定常流动时，流体的速率与流管截面积的乘积是一个恒量。由此可知，当我们将口径边小时，必然导致流速加快。根据个原理在科技上也有很大的运用，比如切割水枪，对于一样的出水量，这种水枪的口径很微小，使得出水的速度极快，所含动能极大，在生产上有很大的运用。
最后，要介绍一个很实用的方法：取水。在家中，看到大人用一根管子插到水里，用嘴在管口吸气，水就会自己流出来，我也试过，但没有成功，现在我目标了原因：必须保证吸气的一端低于出水的一端，为什么呢？这是利用了大气压的原理。当吸气后管子里成为真空，水就被外界大气压压倒了出水端。
物理在我们的生活中有很大的作用，我们可以借着生活来学习物理，再利用物理来服务生活。
