The concept is being used to deal with one possibly dangerous form of waste – electronic junk (电子垃圾), such as old computers, cell-phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.
“A lot of these materials are being sent to developing nations under the excuse of reuse – to bridge the digital divide,” said Richard Gutierrez, a policy researcher.
One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.
Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”
China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial, is finally beginning to take the lead.

Psychologists(心理学家) have succeeded in weakening parents confidence in their own authority. And it hasn’t taken children long to get wind of the fact. In addition to the great modern classics on child care, there are countless articles in magazines and newspapers. With so much advice flying about, mum and dad just don’t know what to do any more. In the end, they do nothing at all. So, from early childhood, the kids are in charge and parents’ lives are regulated according to the needs of their kids. When the little dears develop into teenagers, they take complete control. Lack of authority over the years makes teenagers rebellion against parents all the more violent. If the young people are going to have a party, for example, parents are asked to leave the house. Their presence merely spoils the fun. What else can the poor parents do but obey?
小题1:The author says that today’s parents _______.
A.are bombarded with excessive amounts of child-care literature. |
B.draw a distinction between permissiveness and carelessness. |
C.are only towards children from happy home backgrounds. |
D.weigh their children’s knowledge rather than intelligence. |
A.become used to | B.try to avoid |
C.realize | D.become puzzled of |
A.Victorian child rearing is a model for parents to follow. |
B.Psychologists have much to answer for today’s problems on child care. |
C.With the help of so much advice, raising children is easier than ever. |
D.Parents like to enjoy the freedom when there is a party in the house. |
A.The excessive permissiveness of today’s parents is harmful to children. |
B.Psychologists shouldn’t interfere so much with child care. |
C.Parents should hold the Victorian attitudes towards children. |
D.Children are too sensitive to be hurt. |
There are various kinds of apples, but a very few make up the majority of those grown for sale. The three most common kinds grown in the United States are Delicious, golden Delicious, and McIntosh.
Apples are different in colour, size, and taste. The colour of the skin may be red, green, or yellow. They have various sizes, with Delicious apples being among the largest. The taste may be sweet or tart (酸的). Generally, sweet apples are eaten fresh while tart apples are used to make applesauce (苹果酱).
Apple trees may grow as tall as twelve metres. They do best in areas that have very cold winters. Although no fruit is yielded during the winter, this cold period is good for the tree.
小题1:It can be learned from the text that Delicious apples are _______________
A.grown in France. | B.sold everywhere. |
C.very big. | D.quite sweet. |
A.the growth of apple trees. |
B.producing large apples. |
C.improving the taste of apples. |
D.the increase of water in apples. |
A.be large producers of apples. |
B.be large producers of applesauce. |
C.have the longest history in apple production. |
D.have the coldest winter among apple producing countries. |
A.improved. | B.increased. |
C.produced. | D.sold. |
In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world’s problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential(潜能) of the earth’s resources.
What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.
More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.
All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.
Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world’s needs, using less of the raw materials that are becoming short.
小题1:Which of the following would the author probably agree with?
A.The environment crisis will not be solved unless we stop using virgin(原始)materials. |
B.In scientific research, a higher priority(优先)should be given to understanding all living systems. |
C.Exploration of outer space will finally lead to an improvement on human living conditions. |
D.U. S. high-technology companies are welcoming this new change in scientific research. |
A.a growing number of Americans are doubtful about what high technology can do in solving the world’s problems. |
B.Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world’s problems. |
C.More and more young scientists are trying their best to find new ways to solve the world’s problems. |
D.Technological creativity will still play a very important part in solving the world’s problems. |
A.existing products be improved. |
B.more complex machines and electronic equipment be designed. |
C.ways be found to produce better goods using fewer raw materials. |
D.any new invention and innovation be encouraged in technology |
A.global food shortage | B.resources depletion(耗尽) |
C.environmental pollution | D.all of the above |
A.the development of present techniques cannot provide any answers to today’s problems. |
B.an increasing number of young scientists are taking a great interest in biological and social sciences. |
C.many scientists have come to understand the limits of natural resources. |
D.many scientists argue that high technology is something but not everything. |
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak” with their teachers, their classmates, and their families. however, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”
小题1:The main purpose of the laptop program is to give each student a laptop to _______.
A.use for their schoolwork | B.access the Internet |
C.work at home | D.connect them to libraries |
A.They don’t really talk. | B.They use the computer language. |
C.Laptops have speakers. | D.None of the above reasons is correct. |
A.All teachers use computers. | B.1500 students have laptops. |
C.It is an old college in America. | D.Students there can do everything. |
A.attend lectures on information technology |
B.travel around the world |
C.get information from around the world |
D.have free laptops |
A.The program is successful. | B.The program is not workable. |
C.The program is too expensive. | D.We don’t know the result yet. |
Climate change experts from the Tyndall Climate Research Centre in Britain have said urgent action is needed to curb the rapid growth in air travel if the government is to meet its commitments on tackling global warming. This report from Stephen Evans:
Falling ticket prices and rising incomes are leading to rapid growth in global air travel. According to the British government, the number of British air passengers, for example, will more than double in the next quarter of a century. Increases of such an order would mean much more aviation fuel being burned and aviation fuel may be more harmful to the environment than other fuels because the resulting smoke is emitted at high altitudes.
A group of scientists at the environmental research group, the Tyndall Centre, says that if Britain is to meet its overall target for cutting damaging emissions, other uses of fuel like for heating homes or driving cars would have to be cut dramatically.
The British government wants the use of aviation fuel covered by international agreement on the environment. The difficulty for any individual government is that taxing fuel used at its own airports might push airlines to move their operations to competing airports in other countries.
小题1:Which statement is TRUE?
A.A lot of people around the world have recently stopped flying because they have less money to spend and the price of plane tickets is going up |
B.Half as many people as today will fly in the next 25 years. |
C.Because more planes are suing more flight petrol and more pollution is being produced in the sky. |
D.The British government would like all countries to agree not to tax airline fuel. |
A.The increase of incomes and the decrease of ticket prices. |
B.The growth of the number of good planes. |
C.The falling of the oil price. |
D.The encouragement of the governments. |
A.the number of British air passengers will more than double in the next quarter of a century. |
B.Britain will have to use less energy at home and on the roads to meet the goal of cutting pollution. |
C.If airports are taxed for using fuel by each country’s government, then airlines might use other airports with cheaper fuel taxes. |
D.Only the use of aviation fuel needs to be cut down to meet the overall target for cutting damaging emissions. |
A.Falling Ticket Prices and Rising Incomes |
B.Growth in Air Travel Harms Environment |
C.Rapid Growth in Global Air Travel |
D.More Flight Petrol, More smoke |
