1、大学英语四级模拟试卷 268及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write an essay entitled Advantages of Five-day Week. You should write at least 120 words following the outline given below in Chinese: 1. 对家庭的好处; 2. 对社会的好处; 3. 对个人的好处。 二、 Part II Reading Comprehension
2、(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 (for NO) if the statement
3、 contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Energy crisis The year 1973 brought an end to the era of secure, cheap oil. In October, as a result of the Arab Israeli War, the Arab oil-producing countries cut back oil productio
4、n and embargoed (禁运 ) oil shipments to the United States and the Netherlands. Although the Arab cutbacks represented a loss of less than 7 percent in world supply, they created panic on the part of oil companies, consumers, oil traders, and some governments. Wild bidding (出价 ) for crude oil ensued w
5、hen a few producing nations began to auction (拍卖 ) off some of their oil. This bidding encouraged the OPEC nations, which now numbered 13, to raise the price of all their crude oil to a level as high as eight times that of a few years earlier. The world oil scene gradually calmed, as a worldwide rec
6、ession brought on in part by the higher oil prices cut the demand for oil. In the meantime, most OPEC governments took over ownership of the oil fields in their countries. In 1978 a second oil crisis began when, as a result of the revolution that eventually drove the Shah of Iran from his throne, Ir
7、anian oil production and exports dropped drastically. Because Iran had been a major exporter, consumers again panicked. A replay of 1973 events, complete with wild bidding, again forced up oil prices during 1979. The outbreak of wax between Iran and Iraq in 1980 gave a further boost to oil prices. B
8、y the end of 1980 the price of crude oil stood at 19 times what it had been just ten years earlier. The very high oil prices again contributed to a worldwide recession and gave energy conservation a big push. As oil demand reduced and suppliers increased, the world oil market went down. Significant
9、increases in non-OPEC oil supplies, such as those in the North Sea, Mexico, Brazil, Egypt, China, and India, pushed oil prices even lower. Production in the Soviet Union reached 11.42 million barrels per day by 1989, accounting for 19.2 percent of world production in that year. Despite the low world
10、 oil prices that have prevailed since 1986, concern over disruption (分裂,瓦解 ) has continued to be a major focus of energy policy in the industrialized countries. The short-term increases in prices following Iraqs invasion of Kuwait in 1990 reinforced this concern. Owing to its vast reserves, the Midd
11、le East will continue to be the major source of oil for the foreseeable future. However, new discoveries in the Caspian Sea region suggest that countries such as Kazakhstan may become major sources of petroleum in the 21st century. Current state In the 1990s, oil production by non-OPEC countries rem
12、ained strong and production by OPEC countries rebounded (回弹 ). The result at the end of the 20th century was a world oil surplus and prices (when adjusted for inflation) that were. lower than in 1972. Experts are uncertain about future oil supplies and prices. Low prices have spurred greater oil con
13、sumption, and experts question how long world petroleum reserves can keep pace with increased demand. Many of the worlds leading petroleum geologists believe the world oil supply will peak around 80 million barrels per day between 2010 and 2020. (In 1998 world consumption was approximately 70 millio
14、n barrels per day.) On the other hand, many economists believe that even modestly higher oil prices might lead to greater supply, since the oil companies would then have the economic incentive to exploit less accessible oil deposits. Natural gas may be increasingly used in place of oil for applicati
15、ons such as power generation and transportation. One reason is that world reserves of natural gas have doubled since 1976, in part because of the discovery of major deposits of natural gas in Russia and in the Middle East. New facilities and pipelines are being constructed to help process and transp
16、ort this natural gas from production wells to consumers. In addition to developing alternative sources of energy, energy supplies can be extended by the conservation (the planned management) of currently available resources. Three types of possible energy conservation practices may be described. The
17、 first type is curtailment, that is, doing withoutfor example, closing factories to reduce the amount of power consumed or cutting back on travel to reduce the amount of gasoline burned. The second type is overhaul (检查 ), that is, changing the way people live and the way goods and services are produ
18、ced. For example, slowing further suburbanization of society, using less energy-intensive materials in production processes, and decreasing the amount of energy consumed by certain products (such as automobiles). The third type involves the mare efficient use of energy, that is, adjusting to higher
19、energy costsfor example, investing in cars that go farther per unit of fuel, capturing waste heat in factories and reusing it, and insulating (绝缘的 ) houses. This third option requires less drastic changes in lifestyle, so governments and societies most commonly adopt it over the other two options. B
20、y 1980 many people had come to recognize that increased energy efficiency could help the world energy balance in the short and middle term, and that productive conservation should be considered as no less an energy alternative than the energy sources themselves. Substantial energy savings began to o
21、ccur in the United States in the 1970s, when, for example, the federal government imposed a nationwide automobile efficiency standard and offered tax deductions for insulating houses and installing solar energy panels. Substantial additional energy savings from conservation measures appear possible
22、without dramatically affecting the way people live. A number of obstacles stand in the way, however. For example, productive conservation requires hundreds of millions of people to do ordinary things such as turning off lights and keeping fires properly inflated. Another barrier has been the price o
23、f energy. Low energy prices make it difficult to convince people to invest in energy efficiency. From 1973 to the mid-1980s, when oil prices increased in the United States, energy consumption per person dropped about 14 percent, in large part due to conservation measures. Over time, improvements in
24、energy efficiency are mere than pay for themselves. However, they require large capital investments, which are not attractive when energy prices are low. 2 After the Arab-Israeli War, the cutbacks in oil production in Arab oil-producing countries led to serious shortage of oil supply in the world be
