Nowadays many people are concerned about the problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment.
Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers so they throw them in the trash.
National Solid Waste Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected.
The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills (垃圾填埋场) and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore says, “There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components there are some materials that should not really be in the landfill.”
Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in order to keep e-waste poisons like lead (铅) and mercury (汞) out of garbage dumps.
This year several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted bans on e-waste in landfills. Chaz Miller says more can be done to boost electronic waste recycling.
“We can do much better,” noted Miller. “I think clearly our goal should be to do as well as we do recycling newspapers.”
1.Which of the following does NOT belong to e-waste?
A. Old televisions. B. Old computers.
C. Old cell phones. D. Old newspapers.
2.Why is e-waste banned from landfills in many states?
A. Because it can not be recycled.
B. Because the landfills are already full.
C. Because it might damage the environment.
D. Because it can be shipped to other countries.
3.According to Mike Fannon, what might be the best way of dealing with e-waste?
A. Recycling it. B. Selling it.
C. Burying it. D. Breaking it.
4.What can we learn from the passage?
A. Chaz Miller works for EPA.
B. Miller is optimistic about the future of e-waste.
C. At present, less than 10 percent of e-waste is recycled.
D. All states in the US have banned e-waste from landfills.

Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a nonspecific but stable change. For many people, the hightech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.
In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic genie is out of the bottle.
However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fastgrowing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?
The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.
How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.
1.The passage mainly talks about________.
A. the world's food problem
B. the development in biotech
C. the genetically modified foods
D. the way to solve food shortages
2.According to the passage, GM foods________.
A. will replace naturally grown foods
B. are far better than naturally grown foods
C. may help to solve the problem of poor nutrition
D. can cause serious trouble in developing countries
3.The underlined sentence “The genetic genie is out of the bottle.” in Paragraph 2 probably means that________.
A. GM foods are available everywhere
B. the technology in producing GM foods is advanced
C. genetic technology may have uncontrollable powers
D. genetic technology has come out of laboratories into markets
4.What's the writer's attitude towards GM foods?
A. Enthusiastic. B. Cautious.
C. Disapproving. D. Unbelievable.
