Cities need to put efforts to deal with pollution and clear the air.

       Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council.

       Besides the existing pollution control program for S02, regional emission caps (區(qū)域排放上限) for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region.Coal-consumption caps will also be tried out in some areas, according to the plan.

       The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people's health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.

       The air quality in a city affects the regions nearby because pollutants (污染物)can travel through the atmosphere, said Chai Fahe, vice-director of Chinese Research Academy of Environmental Sciences.

       “So efforts to reduce air pollution in a single city, targeting a certain pollutant will not oe enough," Chai said.

       Zhang said the country's major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years.

       These three regions, home to at least 200 million people, occupy only 6.3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures.

       Studies also show that the visibility (能見度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution.

       Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan.

       The new plan also requires an improved air quality system, which will measure the pollution levels."The current system, which only measures some major pollutants, cannot reflect the true picture." said Chai.

It will not be enough to reduce air pollution in a single city because ______.

       A.a(chǎn)ir pollution has been becoming more and more serious in recent years

       B.a(chǎn)ir pollution like acid rain and smog is threatening people's health

       C.a(chǎn)ir pollutants in a city can travel in the sky and affect nearby areas

       D.a(chǎn)ir pollutants stay in fixed places over the cities

Suppose the visibility in eastern regions of China was 130 km in the early 1960s, the visibility there nowadays is            .

       A.123 to 115 km             

       B.137 to 145 km

       C.123 to 145 km                   

       D.115 to 137 km

The main purpose of the passage is         .

       A.to inform readers of the damage caused by air pollution

       B.to introduce the new plan to control air pollution

       C.to provide official figures of air pollution levels

       D.to point out the regions affected by air pollution

What does the underlined phrase "the true picture" in the last paragraph mean?

       A.The major pollutants.  

       B.The key polluted areas.

       C.The major polluted cities.

       D.The pollution levels.

There are two main things that make aircraft engineering difficult: the need to make every part as reliable as possible and the need to build everything as light as possible. They are to be combined (結合).The fact that an aeroplane is up in the air and can't stop, if anything goes wrong, makes it perhaps a matter of life or death that its performance is completely dependable.

Given a certain power of engine, and so a certain amount of oil, there is a practical limit to the total weight of aircraft that can be made to fly. Out of that weight as much as possible is wanted for fuel radio instruments, passenger seats, or freight(貨物) room, and, of course, the passengers or freight themselves. So the aircraft has to be as small and light as safety will allow. The designer must work out the normal load that each part will bear. This specialist is called the "stress(壓力) man." He takes notice of any unusual stress that may be put on the part as a means against errors in production, accidental damage, etc.

The stress man's decisions go to the designer of the part, and he must make it as strong as the stress man says is necessary. One or two small parts are always tested to prove that they are as strong as the designer wanted. Each separate part is tested, then a whole one-for example, a complete wing, and finally the whole aeroplane. When a new type of aeroplane is being made, normally only one of the first three made will be flown. Two will be destroyed on the ground in strict tests. The third one will be tested in the air.

When a plane has passed all the tests it can get a government permission of flight, without which it is illegal(非法的) to fly, except for test flying.

The main difficulty of aircraft design lies in________.

A. the combination of lightness and reliability      B. the speed and cheapness

C. reliability and passenger comfort             D. its engine power and oil burning

The stress man's job is to work out ________.

A. how safe the plane is                         B. the load that each part bears

C. the possible errors made by designers        D. the amount of load the aircraft may carry Which of the following statements is NOT true?

A. The total weight of an aircraft depends on the power of the engine.

B. An aircraft has to pass all the tests.

C. Permission of flight can be got from the government.

D. It is necessary for all the first planes to be tested in the air.

C
Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(萬億)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid(易吸收的液體). No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen(腹部).
【小題1】Why is the warning in the small print?

A.They think people will not care about it.
B.There is not enough space for the warning.
C.They don’t want the users to pay attention to it.
D.The warning is not important at all.
【小題2】 What does the underlined word in sixth paragraph probably mean?
A.a(chǎn)cceptable B.valuableC.a(chǎn)ccessible D.easily affected
【小題3】What can we conclude from the last paragraph?
A.Pregnant women should keep cell phones away.
B.People should use cell phones in the correct way.
C.If you are a child, you’d better text than make phone calls.
D.When you use a cell phone, use a wired headset or the phone’s speaker.
【小題4】 What does the passage mainly talk about?
A.Be careful when using cell phones.
B.Don’t hold your cell phone against your ear.
C.Rats exposed to radiation have damaged DNA in their brains.
D.Low-energy radiation could damage cells that could lead to cancer.
