　　152. What natural resource that is disappearing needs to be saved?

　　Many parts of the world are losing important natural resources, such as forests, animals, or clean water.

　　Choose one resource that is disappearing and explain why it needs to be saved. Use specific reasons and examples to support your opinion.

　　『分析』

　　很容易的选择，以森林为例：

　　用一段陈述中国的森林被怎样破坏，又是怎样需要大量的树木……

　　然后再说如果破坏了森林，会导致很多自然灾害，进而产生经济损失……

　　树木的好处[155]有详细地说明。

　　『范文』

　　The world's resources are incredibly important, and as the world's population grows higher and faster, it is difficult to hold on to these precious assets. While all resources have their own important uses, I believe that forests are the resource that we should be most concerned about preserving.

　　Trees provide three important functions in the ecosystem. First, they transpire water into the air, creating clouds, and therefore, rain. Without trees, this cycle is interrupted, and rainfall is drastically reduced to minimal levels. Second, trees hold topsoil in place and soften the impact of water on the ground. This is of utmost importance in rain forests, where decomposition is rapid and because of this, the layer of topsoil might only be five to ten centimeters deep. Finally, trees are important to the ecosystem because they protect streams from debris and silt. If the trees were all removed, there would be nothing holding back this dirt from our rivers, destroying the aquatic environment.

　　Trees also, of course, provide natural beauty to a country. This is very important for tourism, as many visitors enjoy going on long hikes through wooded areas, and taking in the beautiful scenery. If a country has no natural beauty, there will be little draw for tourists to come and visit. While cities can be exciting, most people are drawn to these natural jewels.

　　Forested area is also the main habitat for a plethora of animal species. In fact, most of the extinction and endangerment of animals today can be attributed to habitat destruction. If we continue our trend in deforesting the world, we will soon find ourselves living in a barren wasteland, with no wildlife to keep us company. The effects of the extinction of even one species of animal is yet unknown. Breaking the food chain on even one level might have profound ripples through all life on earth.

　　153. Does a zoo have no useful purpose?

　　Do you agree or disagree with the following statement? A zoo has no useful purpose. Use specific reasons and examples to explain your answer.

　　『分析』

　　不能同意，no是绝对修饰词。但是要指出确实有一些动物园不值得保留下去。

　　『范文』

　　Perhaps one of the most blameworthy factors that make some people raise the eyebrow to zoos and criticize that "A zoo has no useful purpose" is its exorbitant price to maintain. However, it is too hasty to say so, since most zoos have their significance, both educational and scientific. Modern zoos act as centers of education and are designed to make learning about animals an interesting and enjoyable experience. They provide visitors with the chance to see rare creatures, such as tigers, zebras, penguins, and giant pandas, which come from many different parts of the globe. Zoos also introduce people to their own local wildlife, offering a valuable learning experience in an increasingly urban world. At the same time, most zoos provide educational programs aimed at a wide range of ages. A visit to a zoo provides children an opportunity to see and touch animals other than household pets. For older schoolchildren, many zoos conduct classes or day trips that focus on different aspects of animal biology and the impact of humans on animal life.

　　Modern zoos also have their scientific imports and can function as a sanctuary for endangered animals and therefore help maintaining ecosystems. In zoos scientists can create an animal population that can become self-sustaining in the wild. An example of a successful reintroduction to the wild is the David's deer. This Asian deer was native to marshlands in northeast China before its habitat was destroyed more than 800 years ago and it became extinct in the wild. Since that time the species has been bred in zoos in China and later in Europe. In 1985 four David's deer were released to the wild in a protected animal reserve in China, where they are now breeding successfully.

　　On the other hand, some experts warn against placing too much reliance on zoos as biological "arks," where species can be protected regardless of environmental changes outside. Critics warn that zoos, like all human institutions, are vulnerable to unforeseen events, such as disease, fires, and financial or social upheaval. More significantly, the number of species that zoos can protect is strictly limited. Today's zoos are home to no more than a few thousand species—only a fraction of the world's animal life. Zoos already have to perform a delicate balancing act between large, crowd-attracting animals and threatened animals that have less visitor appeal. During the 21st century, zoo experts will face even harder decisions about which species they can afford to save.
