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."
【小题1】What does the underlined word "retrieve" (paragraph 2) probably mean?

A.look intoB.take apartC.get backD.throw away
【小题2】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.
【小题3】 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.
【小题4】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

C
Still want a laptop? That was so yesterday. Get ready for the next stage in the personal computer revolution: It's the ultrathin (超薄的), cheap netbook.
According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards. The netbook is a kind of portable computer with learner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow keyboard, and no ODD.
Currently, some of the devices look more like a toy than a full-feature computer. That's because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company's standard laptop chip, so they have trouble running demanding software like games and photo-editing programs.
This year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expert skill to PCs. That means they will break Atom's netbook dominance (统治地位) and reduce the size while letting it run complicated programs.
The big winner in the rise of netbooks will be the consumer. AT&T announced last week that customers in Atlanta, Georgia, US, could get a netbook for just $50 (342 yuan) if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
University campuses are a major target of Shanzhai netbooks—uncopyrighted (无版权的) domestic copies of foreign brands. These products are usually sold at less than 2,000 yuan. But industry insiders suggest students not use these nameless products because many of them don't provide good after-safes services.
49.The following are all advantages of netbooks EXCEPT that      .
A.people can easily edit photographs with them
B.they cost less than other personal computers
C.they are very thin and easy to carry
D.they save power
50.Why are students advised not to use Shanzhai netbooks?
A.Because they are of poor quality.
B.Because they are not easy to operate.
C.Because they will soon be out of date.
D.Because they lack good after-sales services.
51.What can be inferred from the passage?
A.Laptops are becoming more and more popular.
B.University students seldom buy Shanzhai netbooks.
C.Shanzhai netbooks are sold better than those of famous foreign brands.
D.Atom's netbooks make up the largest part of the sales of portable computers at present.
52.What is the general idea of this passage?
A.Shanzhai netbooks are taking control of laptop market.
B.Netbooks have advantages over laptops in everything.
C.Netbooks are becoming the trend of personal computers.
D.Most of the netbooks sold today run on an Intel chip called Atom.

A sandstorm, also known as a dust storm, is exactly what it sounds like. A very strong windstorm especially in the desert carries clouds of sand or dust that greatly reduces visibility. This wind is usually caused by convection currents (对流气流), which are created by intense heating of the ground, and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause higher winds to mix with winds in the lower atmosphere, producing strong surface winds.
Sandstorms can disturb people’s travel, and can sometimes destroy whole roads, and dry flat areas. Similar dust storms can be found on the planet Mars, and are thought to be seasonal. Today, the destruction of forests and too much farming of farmland can lead to sandstorms. Too much use of water resources can also cause sandstorms.
In the United States of America, sandstorms are rare because of the lack of large deserts and more importantly the development of proper agricultural techniques. The last recorded destructive sandstorm in American history was the Dust Bowl, which occurred on July 16, 1971 and was widely recorded by meteorologists (气象学家).
To protect themselves from sandstorms, some people wear protective suits. Special equipment can be fixed in some cars to prevent sand from getting into the engine. Sandstorms can cause coughs, and the sand and dust has also been known to carry “infectious diseases”. Sand particles, unlike dust ones, will block air passages, and cause a person who breathes them in to choke. Dust particles may cause an allergic (过敏的) reaction.
【小题1】Which of the following plays the first part in forming sandstorms?

A.The instability of the sand.
B.The instability of the wind.
C.The intense heating of the ground.
D.The speed of the wind.
【小题2】From the second paragraph, we can learn that at present _______.
A.sandstorms are more often seen on Mars than on Earth
B.sandstorms have led to the lack of clean water resources
C.farming brings more harm than benefits to humans
D.human activities are a major cause of sandstorms
【小题3】The author will most probably agree that ________.
A.there will soon be no sandstorms in the USA
B.humans haven’t thought of any way to deal with sandstorms
C.death caused by sandstorms is increasing all the time
D.humans should make more efforts to stop soil turning into desert
