The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory (呼吸的) illnesses and led to calls for laws to control the pollution.
Pan Shiyi, a celebrity, said he is planning to propose a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents (应答者) , welcomed his proposal.
They have good reasons to stand alongside Pan. The latest round of haze(雾霾)reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide enough protection, so some people have turned to gas masks.
The causes of the frightening smog are rather mysterious, though experts blame too much emissions (排放) and the mountains around Beijing that trap pollution in winter, unless there is enough wind to clear it away. Some critics blamed China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of high-polluting gas fuel.
Meanwhile, some Beijingers have moved their brainstorming discussion to computers. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter limit to industrial and engine gas emissions, and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.Why did Pan Shiyi started an online survey?

“Indeed,” George Washington wrote in his diary in 1985, “some kind of fly, or bug, had begun to eat the leaves before I left home.” But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lighining-bug(萤火虫)。But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.
The American bug could also be a person, referring to someone who was crazy about a particular activity. Althoug fan became the usual term. sports fans used to be called racing bugs, baseballbugs, and the like.
Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, “to install (安装) an alarm”. Now it means a small piece of equipment that people use for listening secretly to others’ conversation. Since the 1840s, to bug has long meant “to cheat”, and since the 1940s it has been annoying.
We also know the bug as a flaw in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as “little problems and difficulties” that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering ‘a bug’ in his invented record player.”We learn from Paragraph 1 that ___________.
A.Americans had difficulty in learning to use the word bug |
B.George Washington was the first person to call an insect a bug |
C.the word bug was still popularly used in English in the nineteenth century |
D.both Englishmen and Americans used the word bug in the eighteenth century |

The passage is mainly concerned with__________.
A.the misunderstanding of the word bug |
B.the development of the word bug |
C.the public views of the word bug |
D.the special characteristics of the word bug |
LONDON --- A British judge on Thursday sentenced a businessman who sold fake(假冒的) bomb detectors(探测器) to 10 years in prison, saying the man hadn't cared about potentially deadly consequences.
It is believed that James McCormick got about $77.8 million from the sales of his detectors - which were based on a kind of golf ball finder - to countries including Iraq, Belgium and Saudi Arabia.
McCormick, 57, was convicted(判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.
"Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people," Judge Richard Hone told McCormick. "you have neither regret, nor shame, nor any sense of guilt."
The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they "lacked any grounding in science" and were of no use.
McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.
"I never had any bad results from customers," he said.Why was McCormick sentenced to prison?
A.He sold bombs. | B.He caused death of people. |
C.He made detectors. | D.He cheated in business |
According to the judge, what McCormick had done _______.
A.increased the cost of safeguarding |
B.lowered people's guard against danger |
C.changed people's idea of social security |
D.caused innocent people to commit crimes |
Which of the following is true of the detectors?
A.They have not been sold to Africa. |
B.They have caused many serious problems. |
C.They can find dangerous objects in water. |
D.They don't function on the basis of science. |
It can be inferred from the passage that McCormick _______.
A.sold the equipment at a low price |
B.was well-known in most countries |
C.did not think he had committed the crime |
D.had not got such huge profit as mentioned in the text |
Below is a selection from a popular science book.
If blood is red, why are veins (静脉) blue? Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker(超级油轮). But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Why do teeth fall out, and why don’t they grow back in grown-ups? Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed(腐烂)and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off. Do old people shrink(收缩)as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy)? Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not. Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system(边缘系统). All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet. If exercise wears you out, how can it be good for you? Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease. |

Jimmy is an automotive mechanic, but he lost his job a few months ago. He has good heart, but always feared applying for a new job.
One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 am and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre of his car. Obviously there was something wrong with the car. Jimmy immediately went up to lend him a hand. When Jimmy finished working on the car, the old man asked him how much he should pay for the service. Jimmy said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, “Well, I could take you to the office for your interview. It’s the least I could do. Please. I insist.” Jimmy agreed.
Upon arrival, Jimmy found a long line of applications waiting to be interviewed. Jimmy still had some grease (油腻物) on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer’s office with disappointed look on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, “Do you really need to be interviewed?” Jimmy’s heart sank. “With the way I look now, how could I possibly pass this interview?” he thought to himself.
Then the interviewer turned the chair and to Jimmy’s surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.
“Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office. I just know you’d be a trustworthy worker. Congratulations!” Jimmy sat down and they shared a cup of well-deserved coffee as he landed himself a new job.Why did Jimmy apply for a new job?

Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across Americas farmland. It has little to do with the usual challenges, such as flood, rising fuel prices and crop-eating insects. The country's farmers are getting older, and there are fewer people standing in line to take their place. National agricultural census (普查) figures show that the fastest-growing group of farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed.
Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of America's farmers, her work is made tougher by a recent blog posting that put agriculture at No.1 on a list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country.
“There couldn't be anything that's more incorrect," Merrigan said. "We know that there aren't enough qualified graduates to fill the jobs that are out there in American agriculture.
In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said.
“I truly believe we're at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm Bureau. "Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture”.
The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers' Coalition has also been pushing for state and federal policy changes to make it easier for new fermers.
Ryan Best, president of Future Fanners of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. The 21 -year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics.“Never before have we had the innovations (创新)in technology which have led to agriculture in this country being the most efficient it has ever been” he said. “There’s really a place for everybody to fit in”What is the new challenge to American agriculture?
A.Fewer and older farmers. | B.Higher fuel prices. |
C.More natural disasters. | D.Lower agricultural output. |
Why is Merrigan visiting universities across the country?
A.To draw federal agriculture officials' attention |
B.To select qualified agriculture graduates. |
C.To clarify a recent blog posting. |
D.To talk more students into farming careers |
According to Matt Rush, American agriculture will provide opportunities for younger people because__________.
A.the government will cover production costs |
B.global food supplies will be even lower |
C.investment in agriculture will be profitable |
D.America will increase its food export |
What do the underlined words "to turn around the statistics" in the last paragraph mean?
A.To re-analyze the result of the national census. |
B.To increase production. |
C.To bring down the average age of farmers. |
D.To invest more in agriculture. |
