Running like the wind, roaring （咆哮） 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 （栖息地） 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．
【小题1】What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?

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 （区域排放上限） 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 （能见度） 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．
【小题1】It will not be enough to reduce air pollution in a single city because ______.

A．air pollution has been becoming more and more serious in recent years

B．air pollution like acid rain and smog is threatening people's health

C．air pollutants in a city can travel in the sky and affect nearby areas

D．air pollutants stay in fixed places over the cities

How much can environment affect intelligence? In one study, striking increases in IQ occurred in 25 children who were moved from an orphanage(孤儿院) to more stimulating（使人兴奋的，使人振奋的） environments．The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults．Later, these supposedly retarded children were adopted by parents who gave them love, a family ,and a stimulating home environment．The children gained an average of 29 IQ points．For one child, the increase was an amazing 58 points．A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points.
Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children．In one study, children from low-income families were given enriched environments from early infancy(婴儿期) through preschool．By age 2 their IQ scores were already higher than those in a control group．More important, they were still 5 points higher seven years later．High-quality enrichment programs such as Head Start can prevent children from falling behind in school.
A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years．These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them．It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society.

What does fizz (气泡) taste like? In Bubbly (多泡的)drinks such as sodas, tiny bubbles give the drink a lift--- and have a distinct taste, In a new study on mice, scientists have connected that fizzy-taste feeling to the ability to taste sourness, such as that of oranges or vinegar.
Scientists first thought the taste of bubbles came from the bubbles bursting on the tongue, but now ate starting to think differently. Charles Zuker, of Columbia University, and his team studied the nervous system of mice to understand how the tongue tastes carbon dioxide, which is the gas that makes up the bubbles.
Animals, including human beings, are able to detect different tastes by using taste buds(味蕾) which pick up tastes in the mouth, and then send them to the brain. In the experiment, different groups of mice were genetically engineered to be missing one of the senses involved in taste. “Genetically engineered” means the researchers were able to turn off the switches for certain senses by changing the genes responsible for taste. The mice in one group could not taste sweet; another, sour; the third, bitter, and the fourth, salt. When the scientists gave carbon dioxide to the mice, the nervous systems of all the mice responded to the gas, except those of the mice that could not taste sour.
This shows that the taste of the bubbles must be sour, and that by turning off the ability of the mice to taste sour, the scientists also turned off their ability to taste carbon dioxide. When they studied the cells that detect sourness, the researchers found a protein attached to the cells that is important to the process of tasting carbon dioxide. When carbon dioxide comes into contact with this protein, the protein knocks off particles called protons. These protons(质子), in turn, travel to the brain, which says ,” Hey! That’s a taste!”
It may seem like a lot of work to get from a can of soda to a taste, but the science of the senses is anything but simple, “  Taste is a challenging system to study,” one researcher says.
【小题1】 What is the most important function of the bubbles?

A．Nervous Systems Understand How the Tongue Tastes.

B．The Process of Taste

C．The taste of Bubbles.

D．Different Animals Detect Different Tastes.

We hear with our ears, right? Yes, but scientists have known for years that we also hear with our eyes. In a study published in 1976, researchers found that people combined both auditory cues(听力提示) and visual ones，like mouth and face movements, when they heard speech.
A new study that looks at a different set of sensory cues adds to a growing body of evidence that suggests such combination is natural. In a paper, Bryan Gick and Donald Derrick report that people can hear with their skin.
The researchers had volunteers listen to spoken syllables. Meanwhile, they connected the volunteers to a device that would blow a tiny puff (气流) of air onto the skin of their hands or necks. The syllables included “ba” and “pa”, which produce brief puffs from the mouth when spoken, and “da” and “ta,” which do not produce puffs. They found that when listeners heard “da” or “ta” while a puff of air was blown onto their skin, they considered the sounds as “ba” or “pa”.
Dr. Gick said the findings were similar to those from the 1976 study, in which visual cues defeated auditory ones — volunteers listened to one syllable but thought it another because they were watching a video of mouth movements corresponding to the second syllable. In his study，he said，cues from sensory receivers on the skin defeated the ears as well. “Our skin is doing the hearing for us,” he said.
Dr. Gick noted that it would normally be rare that someone actually sensed a puff of air produced by another, although people might occasionally sense their own puffs. “What’s so persuasive about this particular effect,” he added. “is that people are picking up on this information that they don’t know they are using.” That supports the idea that combining different sensory cues is natural.
Dr. Gick said the finding also suggested that other sensory cues might be at work in speech perception(知觉) — that, as he put it, “we are these fantastic perception machines that take in all the information available to us and combine it faultlessly.”
【小题1】“Da” or “ta” were considered as “ba” or “pa” when __________.

China is going green．In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market．Toyota’s hybrid car Prius will be ready to drive in China this week．Let’s have a look at the new car．
Any vehicle is a hybrid run on a rechargeable battery and gas．Hybrid cars have special engines, which are smaller than traditional gas engines．The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up．
Step into a Prius, and turn on the engine．The first thing you notice is that it is quieter than a traditional car．At this point, the car’s gas engine is at rest．The electric motor will provide power until the car reaches about 24km/h．If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off．
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two．If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go．
The electric motor recharges automatically using a set of batteries．And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries．When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries．As a result, the car’s batteries will last for around 200,000 miles．
66．The underlined sentence probably means ________.
A．there will be more and more green land in China  
B．China’s new cars are combinations of different green models
C．China is still young and lacking in experience
D．the environment is getting better in China
67. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gas.
B. They have smaller engines than traditional gas ones.
C. They only use 99 percent of their power to run up hill.
D. They are much quieter than traditional cars.
68. We can know from the story that ________.
A. the gas engine recharges the batteries as well as powering the car
B. using the brake suggests that the gas engine should work
C. the car’s batteries will last for around 200,000 miles without being recharged
D. the batteries can be recharged at any time you want
69. The author writes the passage mainly to________.
A. announce plans to develop hybrid vehicles for the Chinese market
B. let people know how to save their gas when driving a car
C. teach people how to drive a hybrid car

70．Which of the following statements is TRUE according to the text?
A．The hybrid car is environmentally friendly．
B．The hybrid car is unable to get itself recharged．
C．The hybrid car has been made in mass．
D．The hybrid car can decide what power to use

John Denver has got international fame as a pop star, songwriter, actor and environmental activist ( 环境保护者). Songs like Take Me Home, Country Road, Rocky
Mountain High and Annie's Song have become very popular. But less than thirty years ago, John Denver was a young man with little more than a fine voice, a guitar, and a dream. Growing up in conservative (保守的) family, he was not believed to drop out of college and head to Los Angeles, where the music scene was flowering. Nor was he believed to succeed.
In Take Me Home, John Denver talked about the story that shaped his life, with the story of the rich inner journey of a shy Midwestern boy. With honesty and cleverness, he wrote about his childhood, the feeling of moving to Los Angeles as the 60s came, his first lucky breaks, his first songwriting success with leaving on a Jet Plane and finally got a world fame.
He also wrote about his relationship with his first and second wife, as well as his parents, his children, his partners through his life and his friends.
Honest and rich in the book that only a natural-born storyteller could write so well, Take Me Home is very good from the beginning to the end. It's like spending a few days with a good friend.

A solar pump(太阳能水泵 ) was built in a desert small village. The pump used the deserts most common resource – sunlight, to increase its greatest need, water. Solar collectors were used to collect the sun’s rays. Flat collectors were used instead of concave (凹的) collectors. Flat collectors can be still and do not have moving parts, which can be broken in sandstorms. The system used the 20C temperature difference between the solar collectors and the ground water to work a steam engine which pumped water from under the ground.
Some of the social effects of the new pump were planed for. Children aged 6—15 used to meet the old men to receive the informal education there. In order to replace this, a school was also included in the project. But the project had not considered the traditional power structure of the village. As soon as the foreign experts left, the two richest men in the village took control of the pump and started selling water to everyone else. The result was that the majority of the people were poorer than before.

Computer programmer David Jones earned $ 150,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a check card (信用卡). Instead, he has been told to wait another two years until he is 18.
He works for a small firm in Liverpool, where most young people of his age are finding jobs. David”s biggest headache is what to do with his money. Though he has high payment, he cannot drive a car, or get credit cards.(信用卡)
David got his job four months ago, a year after leaving school with six O-Levels(普通成绩) and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.
“I suppose $150,000 sounds a lot but I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother $20 a week as he lives with his parents. But most of his spare time is spent working.
“Unfortunately, computing was not part of our studies at school,” he said. “ But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway. I would like to earn a million and I suppose early retirement(退休) is a possibility. You never know when the market might disappear.
11. why is David so different from other young people of his age?
A .He has got a job.                                   B. He lives at home with his parents
C .He does not get out much.               D. He earns a high payment
12. David’s greatest problem is that _____.
A. he can’t be treated as an adult (grown-up) by the bank
B. he can’t make as many games as he wishes
C .he doesn’t know what to buy with the money

C. One has to be young to write computer programs
D. He thinks his firm might close down.

Soaring divorce rates around the globe are affecting the environment, American researchers suggested in a study released Monday.
Michigan State University researcher Jianguo “Jack” Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy. They said housing units require space, construction materials and fuel to heat and cool, regardless of the number of inhabitants.
For example, in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water. An additional 38 million extra rooms required heating and lighting that same year due to divorced households.
“A married household actually uses resources more efficiently than a divorced household”, Liu said. He said that in cohabitating households, people will watch the same television, share the air conditioning and heat and use the same refrigerator, all things that use energy at a regularly stable rate regardless of the number of users.
Liu said he was not condemning divorce, “Some people really need to get divorces.” He said that cohabitation was simply a more environmentally friendly option. Additionally, the researchers noted that trends other than divorce are also changing family living structures, such as the end of multiple generations of a family sharing a home and people remaining single longer.
“People’s first reaction to this research is surprise, and then it seems simple.” Liu said in a release, “But a lot of things become simple after research is done. Our challenges were to connect the dots and quantify their relationships. People have been talking about how to protect the environment and refuse climate change, but divorce is an overlooked factor that needs to be considered.”
He said the increasing energy demands caused by divorce should be considered by governments when they are creating environmental policies.
This passage is mainly meant to ____.
A. inform the reader of the increasing divorce in America
B. emphasize the importance of protecting the environment
C. tell people the effect divorce has on the environment
D. appeal to married people to keep their households
According to the passage, what’s the attitude of Mr. Liu towards divorce?
A. Supportive       B. Objective.       C. Indifferent.       D. Unclear.
It can be inferred from the passage that ____.
A. divorced households will promote the sales of products
B. married households are more willing to protect the environment
C. divorced households contribute more to the society’s development
D. divorce is not taken into account when people are protecting the environment
From this passage we can find that ____.
A. divorce rates are quickly rising globally these years
B. cohabiting households will increase consumption of water and energy
C. to divorce is a wise option according to the passage
D. the end of multi-generations of a family will save energy
