Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更换）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.
The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."
Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.
At present , the U.S. has no federal law for the disposal (处理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (过滤) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."
Which of the following is most likely not to be a form of e-waste?
A. A mobile phone B. A radio C. An e-bike D. A table
What does the underlined word "retrieve" (paragraph 2) probably mean?
A. look into B. take apart C. get back D. throw away

make money.
C. The way uneducated workers deal with old computers does great harm to the environment as well as to their own health.
D. More and more electronic waste is being wasted and thrown away mainly because of
people's bad habits.
What is the purpose of writing the passage?
A. To attract more people's attention to e-waste.
B. To call on people not to throw away e-waste anywhere.
C. To tell people what e-waste is and how to deal with it well.
D. To warn people to break away from the electronic industry.
The next paragraph probably concerns_______.
A. how to deal with e-waste properly
B. how to protect ourselves from harm by e-waste
C. How to slow down the development in the electronic industry
D. how to make full use of e-waste
"Reduce, reuse and recycle, this familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways.
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.
The underlined word “unscrupulous” in Paragraph 1 probably means ________.
A. unsafe B. tricky C. wrong D. immoral
What does the fourth paragraph mainly discuss?
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.
From what Gutierrez said we can learn that ________.
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
It can be inferred from the last paragraph that _______.
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
The passage mainly tells us that _______.
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
I have been consistently opposed to feeding a baby regularly. As a doctor, mother and scientist in child development I believe there is nothing to recommend it, from the baby’s point of view.
Mothers, doctors and nurse alike have no idea of where a baby’s blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.
It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I’ve never heard anything so ridiculous. Baby feeding shouldn’t follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks.
Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding. The research finds out that babies who are fed on demand do better at school at age 5, 7, 11 and 14, than babies fed according to the clock. By the age of 8, their IQ （智商）scores are four to five percent higher than babies fed by a rigid timetable. This research comes from Oxford and Essex University using a sample （样本）of 10,419 children born in the early 1990s,taking account of parental education, family income, a child’s sex and age, the mother’s health and feeling style. These results don’t surprise me. Feeling according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.
I hope this research will put an end to advocating strictly timed baby feeling practices.

When Paul was a boy growing up in Utah, he happened to live near a copper smelter(炼铜厂), and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.
Years later Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was “No.”
Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn’t get his idea accepted.
Paul later got married and had some kids. But his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, “It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges.” Under the cover of darkness, he went secretly into the wasteland and started planting.
And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against the plain common sense. Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.
Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.
1. When Paul was a boy, _____.
A. he had decided never to leave his hometown
B. the economy of Utah depended wholly on the copper smelter
C. no laws were made to protect the environment against pollution
D. he determined to stop the copper smelter polluting the area
2. Why did Paul go to college to study the science of plants?
A. He wanted to find out the best way to save the area himself.
B. He was interested in planting trees since he was young.
C. He wanted to get more knowledgeable people to help him.
D. He thought his knowledge would make his advice more persuasive.
3. What does the underlined phrase “the plain common sense” probably refer to?
A. That it was impossible for trees to grow on the wasteland.
B. That his normal work and life would be greatly affected.
C. That no one would like to join him in the efforts.
D. That he had to keep everything he did secret.
4. The main idea of the passage is that _____.

B. perseverance will work wonders
C. God helps those who help themselves
D. many hands make light work
For over one hundred and fifty years, Americans of all social classes have worn blue jeans． 71 Whether they are worn for work or for fashion today．Strauss' invention continues to be popular not only among Americans but also among people around the world．
