What is red but green, open but closed and old but new?
The answer is: London’s new double-decker（双层）buses.
Red double-deckers are a symbol of the city. Their status was sealed (确定) in 2008 when one bus made the longer-than-usual trip to Beijing to collect a special passenger: the Olympic Flame.
On November 11, a life-size model of the new bus was shown to the media. The Guardian reported that the new design shares some of the features of the much-missed double-decker Routemaster bus. The original Routemaster was introduced in 1956 but December 2005 saw the end of the old bus’s general service. It was because the bus was difficult for some passengers to use and not environmentally friendly. But it can still be seen on two heritage routes in the city.
Its replacements —boxy, modern double—deckers—have failed to win Londoners’ affection.
London mayor Boris Johnson told the BBC that the new buses were “a combination of nostalgia（怀旧）and the latest technology”. “Standing on the back platform of this bus brings a sense of nostalgia but also shows the best part of the latest technology and design, making this bus fit for the 21st Century,” he said.
The new bus also returns to the driver—and—conductor model—a key feature of the original version. It will be quieter than the old type and have a platform offering passengers the traditional hop—on hop—off service.
The first five new buses will be seen on the roads by early 2012.

Harry’s father bought a magazine which gave its readers information about all kinds of products and helped them make the best choice while buying.
Harry borrowed his father’s magazine when he needed a new computer. “I’ll read it and choose the best one.” He said.
The magazine described these computers.

The DGT PC450	The BNK 975XF: AT $3,200	The CGP 8PT
This computer comes with lots of good software. However it does not have much memory and is rather slow. At $2,850 it’s not very good value for money.	This is the most expensive computer we tested. However it is also the most reliable (可靠的). It is very fast and has lots of memory. It is worth the extra money if you can afford it.	At only $1,900. It has lots of memory and is quite fast. However it broke down twice while we were testing it and we cannot recommend (建议) it for reliability.

Three years ago I listened to a lecture on cognition (认知) that changed the way I think about intelligence. There are two types of cognition. The first is normal cognition: the ability to regain knowledge from memory. The second type of cognition is metacognition: the ability to know whether or not you know.
Does this affect intelligence? In traditional education, intelligence is measured by cognitive ability. Some people can easily produce everything they know on a test. But others are awarded with poor grades and considered inferior. But does this inability make them any less intelligent? If the question came up on a task, they could refer to a book or a quick Google search. In reality they’re just as effective as the people that ace a test. They just can’t prove it as easily.
Metacognition is more important to success than cognition. A person with poor cognitive ability, but great metacognitive ability might do poorly in school, but when faced with a challenge, they understand their abilities and take the best course of action. For example, when faced with a question, a person with strong metacognitive ability will deal with it like this. If he knows the answer, but can’t come up with it, he can always do a bit of research. If he knows for sure that he doesn’t know, then he can start educating himself. Because he’s aware of his ignorance, he doesn’t act with foolish confidence. These people might not seem intelligent at first glance, but because they know what they know, they make better decisions and learn the most important things.
However, people with great cognitive ability but poor metacognitive ability may be considered excellent at a young age for acing every test and getting great SAT scores. Unfortunately, they’ve been ruined by poor metacognition: they think they know everything but they really don’t. They are overconfident, fail to learn from mistakes, and don’t understand the slight differences of personal relationships, showing disregard for persons with lower cognitive ability. They may make the worst decisions.
The most important mental power is the ability to know what you don’t know. The recognition of a fault is the first step to improvement. Don’t try to hide a lack of knowledge. For intelligent people this is the toughest lesson to learn.
【小题1】People with great cognitive ability tend to _________.

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.
【小题1】The author’s attitude towards the use of natural resources is _________.

What will we be eating in the future? Here are the top factors that will be affecting the food that ends up on our tables in the new century.
Genetically engineered food Many crops are already genetically engineered, often to produce more food, fight against pests or improve nutrition. But concern is growing over the lasting effects of changing nature. While existing research has found little harm in genetic engineering, a recent study found the flower powder of a genetically engineered corn can kill the normal butterfly. This finding made many people nervous and brought attention to the topic.
Dining out Americans are increasingly eating meals away from home, both in sit-down restaurants and in fast food outlets. In the last decade alone there was a 14 percent decrease in the number of meals eaten at home. At the same time, restaurants are just beginning to really open their doors on the Internet. Websites exist to make restaurant reservations (预约), view menus, and get tips from your favorite chefs. The dining out trend and the demand for high-quality, chef-prepared food have encouraged chefs to spend time out of the kitchen — teaching classes, appearing on TV, and writing cookbooks.
Eating in Eating in doesn’t always mean cooking. Ready-made meals and frozen food sold in supermarkets taste better all the time. Restaurants are offering neatly packaged “food to go”, and meals can be ordered over the Internet. Cooking is not as much as a necessity, as it is a hobby or a special treat.
Agriculture Although American farmers have been hit hard recently by bad weather, low prices and decreasing government help, they can increase grain production not using old farming methods.
【小题1】Which of the following is the main reason for genetically engineered crops?

“Who needs a shopping mall if you have Taobao?” says Wang Lin,28,a writer in Beijing.

Parking has long been a major headache for drivers in Shanghai. The Transportation Department is mapping out a new plan for the city’s parking system. There are one million cars on the road in Shanghai but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses, the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than in February. Industry experts say this suggests that local people have a strong, active interest in buying cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building more parking lots in downtown areas is not practical and doesn’t provide an ideal solution. The idea of “ Park & Ride” system has been suggested. This means that drivers can leave their vehicles in car parks nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will limit the number of parking lots in downtown areas and demand higher parking fees but build more parking areas near main subway and bus stops.
【小题1】The underlined phrase “mapping out” in the first paragraph means __________.

Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world．But last week a report said that there are no more than 30 wild tigers left in south China．
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund．
The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950's, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species．
Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．
"Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能）and can hunt wild animals by themselves at the African base．
" South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物链） and there was a lack of space．"
The tigers should return to China in 2007 when the reservations in Fujian are ready．
1．What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
A．Because it has lost its natural instincts．        B．Because there is not a complete eco-chain．
C．Because there is no space for it．                 D．Because uncontrolled hunting has destroyed its natural living conditions．
2．How is the programme of sending several tigers to South Africa getting on?
A．Its effect still remains to be seen．
B．Two tigers can already compete with their wild cousins．
C．Some of the tigers are already on the road to recovering their natural skills．
D．The tigers should be able to recover their instincts completely by 2007．
3．By saying " but they are nothing like their wild cousins", the writer means that ______．
A．they are no longer feared by other wild animals
B．they don't know how to hunt or kill
C．a complete change has resulted in the species because of breeding
D．to reintroduce them into the wild has become an urgent task
4．What is the purpose of sending young tigers to South Africa?
A．To help the tigers recover their ability to live in the wild．
B．To provide them with a better environment．
C．To get the tigers to go on a tour．
D．To find a complete eco-chain for them．
5．Which one is not the reason for South Africa being chosen as the training place?
A．Because the tigers can hunt wild animals by themselves at the African base．
B．Because South Africans are skilled at dealing with the tigers．
C．Because there is a complete eco-chain and enough space there．
D．Because the country has good natural conditions for the tigers to learn in． 

It is the first report that home-grown food has been contaminated by radioactivity, largely Iodine(碘)-131, since the ministry ordered radiation( powerful and harmful rays that are sent out from radioactive substances) tests on food and water at the end of March in 14 mainland regions including Beijing, Tianjin, and some coastal provinces.
Sample inspections conducted on Tuesday found low levels of radioactive iodine in spinach( a kind of green vegetables) planted in Beijing, Tianjin and Henan province --- about 1-3 becquerels per kilogram (Bq/kg), the statement said.
"The contamination level detected is too low to be harmful to public health," it said.
According to health experts, radioactive iodine can accumulate in humans once ingested in high concentrations and increases the risk of thyroid cancer. But it decays naturally within weeks.
Leafy vegetables grown in the open like spinach, lettuce and leek are among the first foods to be tainted by radioactive deposits.
Raw milk is also susceptible to radioactive contamination as livestock feed on grass.
Tests carried out in March showed spinach and milk taken from farms near Japan's nuclear-stricken area had exceeded(go beyond) government-set safety limits for radiation.
No cases of tainted water or milk have been reported in China but the ministry vowed to further strengthen monitoring.
Wang Zhongwen, a researcher at the China Institute of Atomic Energy's radiation safety department, told China Daily on Wednesday that currently China only had the means to conduct food radiation tests in a few regions.
The statement also said that recent rain in Beijing and Tianjin meant radioactive substances could have fallen on vegetables.
Chen Jicang, a vegetable dealer in Beijing, said on Wednesday that concerns are growing among consumers, businesses and governments across the world.
"We have yet to see any impact on our business from the radiation, but we will keep a close eye on how the issue develops," he said.
He added that most vegetables consumed in Beijing are produced locally, and he might switch to other varieties if spinach sales suffer.
Yang Guoshan, a researcher of radiation medical science at the Academy of Military Medical Sciences, said people could safely eat products that contain low levels of Iodine-131.
"The radiation level is so low that residents don't need to spend any extra effort on cleaning them," he said.
Gao Jie, a 52-year-old resident in Tianjin said she is deeply worried because spinach is a staple part of her family's diet.
"If spinach is radioactive, is there any possibility that other types of vegetables are safe?"
Trace levels of radioactive isotope cesium-137 and -134 were detected in the air in 21 provinces and regions on Wednesday, up from 17 on Tuesday, according to China's National Nuclear Emergency Coordination Committee.

Forget Twitter and Facebook, Google and the Kindle. Television is still the most influential medium around. Indeed ,for many of the poorest regions of the world, it remains the next big thing——finally becomes globally available. And that is a good thing, because the TV revolution is changing lives for the better.
Across the developing world, around 45% of families had a TV in 1995; by 2005 the number had climbed above 60%. That is some way behind the U.S. , where are more TVs than people, and where people now easily get access to the Internet. Five million more families in sub-Saharan Africa will get a TV over the next five years. In 2005 , after the fall of the Taliban（塔利班）,which had outlawed TV, 1 in 5 Afghans had one. The global total is another 150 million by 2013——pushing the numbers to well beyond two thirds of families.
Television’s most powerful effect will be on the lives of women. In India, researchers Robert Jensen and Emily Oster found that when TVs reached villages, women were more likely to go to the market without their husbands’ approval and less likely to want a boy rather than a girl. They were more likely to make decisions over child health care. TV is also a powerful medium for adult education. In the Indian state of Gujarat, Chitrageet is a popular show that plays Bollywood songs with words in Gujarati on the screen. Within six months, viewers had made a small but significant improvement in their reading skills.
Too much TV has been associated with violence, overweight and loneliness. However, TV is having a positive influence on the lives of billions worldwide. _K^S*5U.C
