1、大学英语四级模拟试卷 875及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a short essay entitled Grammar or Communication. You should write at least 120 words following the outline given below: 1英语教学中出现了重交际轻语法的现象 2 这一现象发生的原因及其后果 3我的看法 Grammar or Communication 二、 Part I

2、I Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark： Y (for YES) if the statement agrees with the information given in the passage; N (

4、S The fact that these environmental and health issues do not respect national boundaries implies that solutions to these problems only be global in scope. Concern about the state of the worlds environment has grown domestically and internationally in the 1990s. The growth of Greenpeace as a movement

5、, the limited success of Green parties in Europe, and legislation to halt the destruction of the environment in most developed democracies are concrete indications of the importance of this policy field. The essential problem for the environment, and many other international issues such as health pr

6、otection, comes from the fact that it is a collective good. That such goods need to be preserved is often explained by what is called the “tragedy of the commons“. In villages and towns where there are “common lands“, they are invariably overgrazed (过度放牧 ) by individuals who choose to keep their own

7、 lands under-utilized while they use the common land extensively. In other words, short-term individual, company, or state interests tend to prevail over common concerns and issues. Collective goods are not considered as important as the selfish interests of states, corporations, and individuals. In

8、 the same manner oceans are over fished and parklands destroyed. The advance of scientific knowledge and technology has brought immeasurable good and bad consequences for humankind. It has been responsible for improvements in health, nourishment, and physical labor, but its side effects are often da

9、ngerous. Environmentalists have pointed out many ways that humans are destroying the planet. They have shown that state borders do not count for very much with regard to environmental issues. Policy must, therefore, be developed at a level above the stale-in other words, internationally. Here are so

10、me examples of environmental issues that call for global action: Ozone The release of harmful man-made gases is destroying the ozone layer that protects the earth from ultraviolet rays (紫外线 ). In the mid-1980s scientists discovered that this thin layer of ozone encircling the stratosphere was being

11、destroyed by the emission of chlorofluorocarbon (CFC) (含氯氟烃 ) gases and bromine from halons (哈龙 ) into the atmosphere. As the ozone layer is destroyed, it allows more ultraviolet light to reach the earth causing increased incidents of skin cancer, endangering marine life and possibly affecting the c

12、limate. In response the developed democracies signed and later amended a Montreal Protocol on Substances That Deplete the Ozone Layer, which freezes and eventually begins to decrease the use of CFCs and halon production. Global Warming Global warming is taking place at an alarming speed. This so-cal

13、led “greenhouse“ effect is caused by the release of pollutants-CFCs, methane, nitrous oxide, and ozone-into the atmosphere and by the destruction of the rain forests. The destruction of forests reduces the earths natural ability to extract carbon dioxide from the air. In other words, industrializati

14、on is causing the earths climatic conditions to change. The so-called First World countries contain only 25% of the worlds population yet consume 75% of its energy, 85% of its forest products, and are responsible for 75% of global warming. Country participants at the 1992 Earth Summit in Rio de Jane

15、iro drafted conventions of climate change, biological diversity, and forests. Although governments were satisfied with the enunciated (确切表明的 ) goals, environmentalists criticized the protocols because they contained no targets or timetables. Renewable Resources The earths vegetation (植被 ), too, is d

16、eteriorating. Forests are being destroyed and plant and animal species are becoming extinct. This waste of renewable resources is the subject of much controversy and is covered by a large variety of international treaties and protocols. Possibly the most important concept in this field is sustainabl

17、e development. In 1987, the authors of Our Common Future, published by the UN Commission on Environment and Development, called for a commitment to the idea of sustainable development. It asked states and individuals to understand that the environment must be protected at the same time as economic g

18、rowth takes place. The sustainable development concept calls for both values to be considered in tandem (合作地 ), not in opposition. Our Common Future stressed the need of the worlds poor and the necessity for limits to be imposed on technology and social organization. Nuclear Issues The breakdown of

19、nuclear plants may create deadly radioactivity as happened in the Chernobyl disaster in USSR. As well, states continue to prepare for the non-peaceful use of nuclear energy. Nuclear testing continues. In 1995-1996 France again tested underground nuclear explosions in the South Pacific. Greenpeace sh

20、ips tried to sail in the waters but were prevented by French military personnel. Rioting in Papeete, the capital of Tahiti, did not halt the tests, but world pressure finally caused French President Jacques Chirac to cancel the tests as of January 1996 after six explosions. Biology Biological resear

21、ch may lead to major international issues. One example is gene splicing (recombinant DNA), which could lead to the inadvertent development of new violent microbes. Questions about global health include such topics as poverty, food production, housing, and disease. However, one disease, acquired immu

22、ne-deficiency syndrome (AIDS) has become so widespread and dangerous that it belongs alongside environmental and population issues as being of world concern. As of 1992, 12 million adults and over 1 million children have been infected with human immune-deficiency virus (HIV), which is widely believe

23、d to be the cause of AIDS. And more than one out of four who had HIV has contracted the deadly disease. The AIDS epidemic is now widespread throughout the world. In all cases HIV damages ceils involved in the immune system, which then makes the body vulnerable to infections. AIDS is transmitted from

24、 person to person by an exchange of bodily fluids through sexual contact, blood transfusions, shared IV needles, and open sores. The highest rates of AIDS are found among homosexuals and even heterosexuals (异性恋者 ) who do not practice safer sex (i.e., use condoms) and drag abusers. These are only som

25、e of the international issues concerning the environment and health issue only governments can solve. But the issues are complex and values about them are often conflicting. Should one push up the cost of industrial production in order to eliminate toxic wastes? Should we preserve the Amazon rain fo

26、rest if it means a reduction of employment for poverty stricken Brazilians ?
