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.

A.positive | B.uninterested | C.optimistic | D.critical |
A.they had no idea about scientific forestry |
B.they had little or no sense of environmental protection |
C.they were not aware of the importance of nature study |
D.they had no idea of how to make good use of raw materials |
A.we plant more trees |
B.natural sciences be taught to everybody |
C.environmental education be directed toward everyone |
D.we return to nature |
A.Our living space on the earth is getting smaller and smaller. |
B.Our living space should be measured in cubic volume. |
C.We need to take some measures to protect space. |
D.We must preserve good living conditions for both birds and animals. |

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 _________.
A.do well in tests | B.be considered inferior |
C.be more effective than others | D.do research when faced with a task |
A.starting educating himself | B.taking action during the course |
C.making the right decision | D.coming up with many ideas |
A.lack basic moral values | B.have improper self-evaluation |
C.fail to communicate with others | D.show little respect for others |
A.intelligence is measured by cognitive ability |
B.cognition is the most important mental power |
C.the toughest lesson is to distinguish the two types of cognition |
D.the awareness of one’s ignorance contributes to one’s improvement |
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 |

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.
小题1:Which of the following shows that red double—deckers are a symbol of London?
A.They have a long history and are seen everywhere in London. |
B.They have nothing in common with the traditional Routemaster bus. |
C.One such bus went from London to Beijing to collect the Olympic Flame. |
D.They carried British athletes from London to attend the Beijing Olympics. |
A.The bus came into use in the 1960s. |
B.The bus was banned because it was harmful to the environment. |
C.Passengers didn’t like the bus because it was slow. |
D.Visitors to London cannot see such buses on the roads any more. |
A.has not been as well received as was expected |
B.will be widely used in London in 2012 |
C.is the most environmentally friendly bus in the UK |
D.combines the latest technology with key traditional features |
A.The buses will make no noises. |
B.The buses will have no conductors. |
C.They will be equipped with air – conditioning. |
D.The bus platform will offer passengers a traditional service. |
Earthquakes, heat waves, floods, volcanoes, super typhoons, snow storms, landslides and droughts killed at least a quarter of a million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
"It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.
And we have ourselves to blame most of the time, scientists and disaster experts say.
Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird(古怪的) year for everything from wild weather to earthquakes.
Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable(脆弱的) buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.
Disasters from the Earth, such as earthquakes and volcanoes "are pretty much constant," said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. "All the change that"s made is man-made."
The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people - many of them living in poverty - and more poorly built shanties than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
In February, an earthquake that was more than 500 times stronger than the one that struck Haiti hit an area of Chile that was less populated, better constructed, and not as poor. Chile"s bigger quake caused fewer than 1,000 deaths.
Climate scientists say Earth"s climate also is changing, bringing extreme weather, such as heat waves and flooding.
In the summer, one weather system caused oppressive heat in Russia, while farther south it caused flooding in Pakistan that inundated 161,200 square kilometers, about the size of Wisconsin. That single heat-and-storm system killed almost 17,000 people, more people than all the worldwide airplane crashes in the past 15 years.
Scientists have calculated that the killer Russian heat wave—setting a national record of 43.9℃—would happen once every 100,000 years without global warming.

A.list the natural disasters that occurred in 2010 |
B.give the details of some natural disasters of 2010 |
C.warn that more natural disasters are to strike |
D.blame humanity for not helping those affected by the disasters |
First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (肿大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.
Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.
Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.
Follow these steps when treating minor burns at home:
1) If the skin is not broken, run cool water over the burn for several minutes.
2) Cover the burn with a sterile (消过毒的) bandage or clean cloth.
3) Take aspirin to relieve any swelling or pain.
Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:
1) Remove the person from the source of the burn (fire, electrical current, etc.).
2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.
3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.
4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments (药膏) or ice on the burned area or break blisters.
5) Monitor the patient for signs of shock, and treat accordingly.
小题1:The underlined sentence in the first paragraph probably means “______”.
A. They can be dangerous if you don’t treat them seriously
B. They range from slight burns to deadly ones
C. They seldom cause deaths even if not treated properly
D. They usually cause deaths if not treated properly

A.what kind of treatment they need |
B.what kind of tissue of the body is damaged |
C.whether there is pain and what degree of pain there is |
D.which layer of skin is burned |
A.if there is severe pain, then you need medical treatment |
B.first-degree burns don’t require medical treatment |
C.burns without pains can be treated at home |
D.the larger the swelling is, the more serious it is |
A.you shouldn’t cover the burn with a bandage or cloth if it is severe |
B.you shouldn’t move the person unless you know how to do first aid |
C.you shouldn’t run cool water over the burn if the skin is broken |
D.you shouldn’t place any wet towels on the burned area |
