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(更換)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 (處理) 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 (過(guò)濾) 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."
What does the underlined word "retrieve" (paragraph 2) probably mean?
A. look into B. take apart C. get back D. throw away
What of the following statements is true according to the passage?
A. The U.S. has strict national laws for dealing with e-waste.
B. Third world countries import e-waste to get valuable parts, which is a safe and easy way to 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

While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(發(fā)射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA

“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.
