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.
小题1:The underlined word “unscrupulous” in Paragraph 1 probably means ________.
| A．unsafe | B．tricky | C．wrong | D．immoral |
| A．Old computers and TVs still work before they are sent abroad. |
| B．Poor people break up e-waste to collect some valuable materials. |
| C．A lot of e-waste is dumped in developing countries. |
| D．The problem of e-waste is growing in developing countries. |
| A．exporting countries should mainly be responsible for this problem. |
| B．neither rich nor poor countries should be blamed for this problem |
| C．developing countries should be responsible for this problem |
| D．poor countries should blamed for this problem |
| A．China has hidden a large amount of e-waste in many secret places |
| B．China has greatly changed hre idea about the problem of e-waste |
| C．China has prevented poisonous materials from entering China for a long time |
| D．China is falling behind other countries in dealing with e-wast |
| A．developing countries are facing serious environmental problems |
| B．e-waste is a growing problem in developed countries |
| C．e-waste is sent to developing countries under the excuse of reuse |
| D．developing countries are making full use of e-waste |
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. |

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. |
