Why does this phenomenon appear? I think there are several possible reasons for this. First, with a rapid growth of population (/as the human population expands), more and more people came to(逐渐开始) live where some wild species have been living. Then these species have to move to other places. Some of them probably cannot adapt to the new environment and die. Second, although many people look on the wildlife as their friends, some people may not think so. They catch a lot of wild animals and sell them in order to get more money. Third, with the development of industry, the natural balance and the ecological environment are destroyed. The deforestation(采伐森林) has become more and more serious. So(锁定这一段, 连接手段，必须有) some of the wild lives become homeless and extinct.
In order to protect the wildlife, I have some suggestions. First, the governments should make laws to prevent them from being caught and killed. Second, the governments should educate people to love nature and protect it. Third, as for ourselves, we should take practical actions to protect our living environment.
胡老师写的作文(写作的语言意识）
在写一些文章时，不可避免的会有一些核心概念，避免重复。
①人口增长 野生动物 灭绝 构成威胁
(背诵9)The two charts show that the ①increase in the U.S. population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to the ecological balance.
As the human population ②expands, more and more wild animals are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population ③growth and economic development. This makes us wonder if man is able to share this planet in harmony with other life forms.
In my opinion, it is imperative(迫切的) to take steps to reverse the disturbing(令人困惑的) trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more importantly, man must learn to stop polluting the environment, or he himself will become extinct.
举例时，有两种方式：
1． 举几个例子，每个例子都是高度浓缩，高度的提炼。
2． 举一个例子，把这个例子细化。
最后要有一个主题句，在后面锁定段落
范文十一
Statistics in People's Daily Expenses in Xi'an
YearItem 1995 1996 1997 1998 1999
Food 66 61 48 41 36
Clothing 9 10 12 15 18
Recreation 4 5 8 9 11
Others 21 24 32 35 35
Total 100 100 100 100 100
(背诵10)What is shown in the table above indicates that dramatic changes have taken place in the people's daily expenses in Xi'an from 1995 to 1999. The expenses on food have declined by 30% while those on clothing and recreation have increased respectively by 9% and 7%. The statistics of rise and fall seem to exist in isolation but closely related to one another.
There are two factors accounting for these changes. Development in economy is an essential one in the five years. The increased income resulting from economic growth plays an important part in the less expense on food. Hence, a small percentage of total income is enough to cover food expense. Another one is the changes in life style. When food presents no worry to the average, people begin to focus more of interest on handsome appearance and happy leisure time. As a result of
such a shift, spending on clothing and recreation increases year after year.
From the analyses made above, we may come to the conclusion that people's living standards in Xi'an have been constantly improved between 1995 and 1999. With the further growth in economy and more changes in life style, the tendency indicated in the table will continue in the better direction.

最新大纲样题（2001年）：情景+提纲+图表*图表语言*
Directions:
Widespread tobacco consumption has led to grave consequences, yet the tobacco companies still claim that they make a valuable contribution to the world economy. There is a discussion in a newspaper on the above two viewpoints. Write an essay(包含评论,议论) to the newspaper
1) criticizing(评论,不一定是批评) their view and
2) justify your stand.
In your essay, make full use of the information provided in the pictures printed below.
You should write about 200 words on ANSWER SHEET 2.
!!小心:把图看懂，图的导向是什么，以此明确你的立场。
(背诵11,重点)The majority of people would agree that cigarette smoking has caused serious problems. But the tobacco companies insist that they contribute greatly to the world economy by paying taxes to the government and employing hundreds of workers.
（当他的情景部分是两个观 点，而图表本身又暗示了一个观点，在第一段要点击对方的观点，但是绝对不展开。也不要写的太长。）
Personally, I believe that cigarette production and consumption threatens to do more harm than good. Firstly, smoking is responsible for（是造成什么原因） many fatal diseases such as lung cancer, heart diseases and so on. According to the survey, tobacco consumers account for about 20% of the world population, and among them, three million people die from smoking-related diseases every year. The fact that the output of tobacco production is reduced from 143.64 billion pounds
in 1994 to 142 billion pounds in 1995 also suggests that people have come to realize the negative effects of smoking. Secondly, tobacco consumption is extremely wasteful of money. As is indicated in the pictures, 200 billion US dollars is lost due to smoking each year. Obviously, the total loss of money around the globe substantially exceeds(大大超过) the gain in the industry.（*全部来源于数据*仅是描述）
(不能这么写:表层结构写出来，思考就生成观点。数据就变成论证。)
(!!特殊要求：图表语言!!)
In conclusion, as the economic development aims at making our life better, we cannot sacrifice our health for short-term financial benefits. If we have to spend more and more money providing medical services for those who suffer from smoking-related illnesses, the notion of promoting economy via tobacco production is not justifiable. It is high time that we fought for the total tobacco ban.(第一段和最后一段前后呼应)

Directions:
A. Write an essay discussing(讨论) the two opposite opinions given below, give both some reasons, and make your comments or suggestions.
There are two main opinions concerning the development of private cars in China: One maintains that their free development should be encouraged, while the other argues that it must be sternly restricted.
B. Time limit: 40 minutes
C. Word limit: about 200 words
D. Your essay must be written clearly on ANSWER SHEET Ⅱ.
(背诵12)Should the development of private cars be encouraged or restricted in China? To judge this issue, we should look at three aspects: What are the advantages of private cars; what are their disadvantages; and is China ready for the free development of private cars?
First of all, the private car is a symbol of freedom. It enables an individual or a family to travel anywhere and at any time, without relying on public transport. It is convenient for shopping and transporting children to and from school. Moreover, in the case of illness, it can carry its owner or other sick person to hospital without delay. However, too many private cars can lead to traffic jams, thus slowing down life and work rather than speeding it up. In addition, automobiles are major polluters of the atmosphere. And, last but not least, the more cars there are on the roads, the more traffic accidents occur.
It seems to me that China, at its present stage of development, should restrict the number of private cars. For one thing, it would be a waste of resources to build a huge automobile industry at a time
when only a few people can afford to buy cars. For another, the country must first bring pollution under control before adding to the problem with more cars.

目前我国高考竞争愈演愈烈。每年考生人数近300万，而录取率在40%以下，多数考生肯定要 落选。这给考生、考生的家庭和学校，乃至整个社会，都造成了很大压力，引发了一些社会 问题。此外，不同类型或特点的考生用同一模式和难度的试卷，有欠公允；三天的考试成绩 便决定一个人的未来命运，亦不够合理。如何解决这些问题，改革现行的高考制度?我的 意见是…。
（看成三点：1 现状 2原因 3建议措施）
背诵13
Statistics show that no more than 40% of people who take the college entrance exams pass. Because a college education is regarded as the key to a successful career, this puts enormous pressure on the applicants. It also causes social problems, as those who fail consider that they have disgraced their families.
It seems to me that the exams are unfair, for three reasons: First, applicants with different abilities are faced with the same type of exam paper, second, the results of a mere three days of examination affect the applicant's whole future; and third, applicants who can afford private tutors usually score higher marks than those who are poorer,
