The United States is the world's largest consumer of energy. We use electricity, gas and oil to light and heat our buildings and run our cars. The demand for power is growing. But we may not need to build new power plants or find more oil. The best way to increase our supply of energy is to be more efficient.
Did you know that when you leave your video-game console (游戲機(jī)操縱臺(tái)) on, it consumes more electricity than two refrigerators? Or that those funny-looking, twisty bulbs (燈泡) use 75％ less power than traditional light bulbs? We have the tools to save money, reduce pollution and even help our planet, simply by wasting less energy.
As President, Barack Obama plans to make energy efficiency in American a major goal. He has promised to cut 15% of all energy used by the Federal Government. In a speech, he called for 75% of government office buildings to be updated for better efficiency. He pointed out that energy-efficient buildings and homes will save consumers billions of dollars on energy bills. An “extra benefit”, he added, will be “a cleaner, safer planet.”
Gas, coal and oil are called fossil fuels. Fossil fuels have been the world's main source of energy for hundreds of years. But burning them releases dirty gases, which cause pollution.
There are two main ways to save energy. The first is to use more efficient machines. Hybrid cars use less gas. New appliances are designed to use less electricity. Today's refrigerators are three times more efficient than those before 1973. Laptop computers consume much less energy than desktop computers.
The second is to use machines more productively. According to the US Department of Energy, in the average home, 75％ of the electricity used to power electronic equipment is standby power (備用電源) . That means power flowing to plugged-in appliances whether or not they are being used.
Homeowners can avoid wasting power by pulling the plug on appliances when they are not in use. Efficiency experts argue that today's best techniques could cut US oil and gas use in half, and reduce our electricity use by three-fourths.
小題1:By referring to Obama's plan, the author mainly intended to say that _______
A．the US government office buildings have wasted the most energy
B．Obama has decided to take the lead to cut down the use of electricity
C．it is time for the US to shoulder the responsibility for a cleaner planet
D．the US is determined to improve energy efficiency in the whole America
小題2:It can be inferred from the text that ________.
A．to build new power plants or find more oil is no longer useful
B．burning fossil fuels can lead to a growing demand for power
C．everyone can make a difference by wasting less energy
D．most of the electricity is wasted with appliances plugged-in
小題3:What would be the best title for the text?
A．The world's largest consumer of energy
B．The world's energy efficiency movement
C．We need to find new energy
D．We have to be more energy efficient

小題1:D

By 2050
Futurologists（未來(lái)學(xué)家）predict that life will probably be very different in 2050.
TV channels（頻道）will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big computers prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices（設(shè)備）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones（克�。﹐f animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
小題1:According to the passage, the following can be realized today EXCEPT __________.
A．reading newspapers on a computer
B．making a space shuttle go into space and land on Earth again

小題2:We can learn from the passage that some big companies prefer robots to human workers, because human workers __________.
A．can work 24 hours a day
B．often ask for more pay
C．a(chǎn)re not clever enough
D．a(chǎn)re often late for work
小題3:From Paragraph 5 we can infer that __________.
A．there will be no blind and deaf people by 2050
B．few diseases will attack people by 2050
C．devices are connected directly to the brain to help people hear
D．medical technology will be more effective by 2050
小題4:What is the author’s attitude towards the cloning technology?
A．The author does not support the use of cloning technology.
B．The author thinks human cloning is impossible.
C．The author does not really support the idea of human cloning.
D．The author is quite excited about human cloning.

Not everyone goes to university after high school graduation. Some work, others join the army and an increasing number worldwide are taking a “gap year” to travel or do community service in their own countries or abroad. They are studying sharks off the Australian coast, building schools in Mexico and learning Spanish or Italian.
The concept of a gap year may not be new, but the recent surge (涌現(xiàn)) of interest certainly is.  Some students are putting off admissions. Others, who don’t get into the college of their choice, are taking a year to explore new frontiers before reapplying.
Students are choosing to take a breather; they are thinking. They are not sure what they are going to do. They are going and exploring some of their interests. They are getting experience they can take to the school they finally go to.
It is an idea actively encouraged by colleges. Princeton University has just launched a “bridge year” program that will send 10 percent of its incoming class to do volunteer work abroad, starting in 2009. And the Harvard has spent the last 30 years urging incoming students to take a gap year.
“Many speak of their year away as a ‘life-changing’ experience or a ‘turning point’” says Harvard admissions director Marlin Lewis. “Many come to college with new opinions about their academic plans, their extracurricular interests and the career possibilities they observed in their year away.”
小題1:The reasons why some take a gap year are the following EXCEPT that ________.
A．they hate studying
B．they don’t know what to do
C．they want to get experience
D．they want to know their real interests
小題2:A student won’t ________ in a gap year.
A．travelB．join the army
C．do community serviceD．learn a foreign language
小題3:After a gap year, one would probably _________.
A．take another year off
B．earn a lot of money
C．be refused by his college
D．have new ideas about their future career
小題4:From the passage we know that ________.
A．more and more students will take a gap year
B．fewer and fewer colleges will encourage his students to take a gap year
C．the gap year can only give one some experience about society
D．nobody will change his own interests after the gap year

If you are looking for an animal to take the title of “most violent fish in the sea”, then the tiger puffer (河豚) fish would have to be a strong contestant. Not only is it deadly poisonous --- though that doesn’t stop people trying to eat it --- but it is also able to scare off enemies by inflating itself to become much larger than normal, when it is young it even chews on its own brothers and sisters.
Tiger puffer fish attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. Then the larvae (幼魚(yú)) move to the entries of rivers and lakes once they have grown a little. Then, having put on a lot of weight, they head out to sea. There’s no innocent childhood for the puffer fish, as Shin Oikawa of Kyushu University in Japan and his colleagues found out when they put the larvae of tiger puffer fish in the lab and monitored them for two months. They found that the larvae went through three steps in which their metabolic(新陳代謝) rates increased dramatically when they reached body weights of 0.002g, 0.01g, and 0.1g. When a larva went through one of these steps, its behavior also changed. For instance, once a larva had passed the first level it would have grown its first tooth and could start attacking larvae that had not yet reached that stage. Similarly, any larva that had reached the 0.01g or 0.1g levels would start attacking lighter larvae.
The researchers noted that the baby fish had a “relatively small mouth”, so rather than swallowing their brothers and sisters whole, they would bite pieces out of them. Despite this limitation, the fish caused plenty of deaths --- up to 12 per cent of the deaths that happened in the lab each day.
Those fish that grew fast enough to be able to chew on their fellows had an advantage. The extra food accelerated their growth and development. Tiger puffer fish are likely to be faster and swifter, so they can deal better with enemies.
As the name suggests, puffer fish can inflate to make themselves seem much larger than they really are, thus scaring off enemies. They do this by filling their stomachs, which are extremely elastic(彈性的), with water. If that’s not enough of a threat, the tiger puffer fish --- like most of the other puffer fish in the family --- carries a deadly toxin(毒素). Eat one puffer fish and the poison will paralyze (癱瘓) your muscles, including the muscles responsible for breathing, so death is usually caused by a lack of oxygen. Famously, the fish is a delicacy in Japan, where highly qualified chefs produce dishes that contain the safe level of the poison. Interestingly, the puffer fish does not go to the trouble of producing the poison itself. Instead, it hosts bacteria (細(xì)菌) that produce the stuff. It obtains these bacteria from its diet, so the youngest adult fish are not poisonous.
小題1:All of the following statements account for the violence of puffer fish except that_____.
A．they are very difficult to catch
B．they can become larger to threaten enemies away
C．they kill their younger companions as they grow up
D．they are deadly poisonous
小題2:We can learn from the second paragraph that puffer fish _____.
A．can only grow to a weight of 0.1g
B．do not change their behavior as they grow up
C．like to find a safe place to hatch the next generation
D．begin to grow teeth when they reach the third level
小題3:Where does the poison in the puffer fish’s body come from?
A．Its inner organs.B．The air it breathes in.
C．The diet it eats.D．The bacteria around it.
小題4:Which of the following statements is TRUE according to the passage?
A．Puffer fish can only produce poison when they face danger.
B．People like eating puffer fish even though they are poisonous.
C．The larvae are more aggressive than adult puffer fish.
D．Young puffer fish taste better than adult puffer fish.

The common cold is the world’s most widespread illness, which is plagues(疫病) that people receive.
The most widespread fallacy(謬誤) of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the Auschwitz Concentration Camp(奧斯維辛集中營(yíng)), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet（濕透）in drafty（通風(fēng)的）room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other time, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.
小題1:The writer offered _______ examples to support his argument.
A．4B．5C．6D．3
小題2:Arctic explorers may catch colds when _______.
A．they are working in the isolated arctic regions
B．they are writing reports in terribly cold weather
C．they are free from work in the isolated arctic regions
D．they are coming into touch again with the outside world
小題3:Volunteers taking part in the experiments in the Common Cold Research Unit probably _______.
A．suffered a lotB．never caught colds
C．often caught coldsD．became very strong
小題4:The passage mainly discusses _______.
A．the experiments on the common cold
B．the fallacy about the common cold
C．the reason and the way people catch colds
D．the continued spread of common colds

Following some of the tips for green living helps save our planet. All of these involve just a few changes to our daily habits.
Just walk and limit the use of your car. One of the poster images of pollution is our vehicles. It burns fuel. It is not as efficient as we hope it could be, and we use it every single day. To lessen the effects of the air pollution caused by our vehicles, we should limit their use. If we can walk to our destination then just let us go. Not only do we lessen our carbon dioxide emissions, but we also get a good exercise out of it.
Use a laptop instead of a computer desktop. Laptops are more energy efficient compared to their bigger counterparts. A laptop is generally 50 percent more efficient in using electricity. Aside from that there are other benefits of a laptop. It is portable so you can work anywhere you like and that you get powerful features without the large size of desktop units.
Turn off the faucet while you are brushing your teeth. It is always a better idea to use a glass when we are brushing our teeth and not to just let the faucet keep on running. Therefore，there is less water to waste while we are cleaning our pearly whites. Simply turn off the faucet when you are not using it.
Make good use of natural light. We have a great and natural lamp --- the sun, and we should learn how to take full advantage of it during daytime. So instead of turning on our lights or lamps even if it is still not evening, we should pull up the drapes and let the natural light come in from the windows.
These are just some of the best tips for green living, but of course there are still many of these tips if you just search for them. But you can do your own variation any time just always prioritize how you can use less energy and produce even lesser trash and pollution.
小題1:What’s the best title for the passage?
A．How to Save Our Planet
B．How to Change Our Daily Habits
C．Tips for Green Living Today
D．Green Living and Serious Pollution
小題2:Compared with a computer desktop, a laptop __________. 
A．less energy efficientB．faster at workC．easy to repairD．easy to carry
小題3:How many tips does the passage mention for green living today?
A．ThreeB．FourC．FiveD．Six

In 1953, the New Zealander Edmund Hillary, then 33, joined a British Qomolangma expedition led by Colonel John Hunt. Tom Bourdillon and Charles Evans were the first team to attempt the summit (頂峰). Despite a violent storm, they reached the South Summit — at 28,700 feet (8,748 meters) — by 1 p.m. on May 26. But both men knew they would run out of oxygen if they went on. They agreed to turn back.
Two days later, Hillary and Norgay, set out from Camp IX at 25,900 feet to make the next attempt. At 27,900 feet they made a temporary camp on a six foot wide rock to spend the night. At 6:30 the next morning, cheered by clearing skies, the team moved out. Roped together, cutting steps with their ice axes, they inched up a steep, knife-edged ridge (山脊) southeast of the summit. They reached the South Summit by 9:00 a.m.
Farther up, they met a 40-foot icy rock face, which was later named the Hillary Step. “…looking up at the rock step at 29,000 feet, it really did look extremely difficult to overcome,” said Hillary. But they found a narrow crack on the surface of the rock, just large enough to move inside on hands and knees, and managed to climb it by supporting feet against one side and backs against the other. Hillary said, “That was really the first moment during the whole of the expedition that I was confident that we were going to get to the top.” 
The last few yards to the summit were relatively easy. “Then I realized that the ridge, instead of rising ahead, now dropped sharply away,” Hillary said. “I looked upward to see a narrow ridge running up to a sharp point. …and we stood on the summit.” It was 11:30 a.m. on May 29, 1953.
小題1:What is the passage mainly about? 
A．The climbing history of Qomolangma.
B．The life and achievements of Edmund Hillary.
C．How Hillary and Norgay conquered Qomolangma.
D．How the Hillary Step got its name.
小題2:At what height did Hillary and Norgay set out on May 29? 
A．25,900 feet. B．27,900 feet.
C．28,700 feet. D．29,000 feet.
小題3:According to Paragraph 2, one of the main advantages to Hillary and Norgay was        .
A．fine weather conditionsB．good rest the night before
C．enough food suppliesD．good climbing skills
小題4:When looking back, Hillary described the Hillary Step as        .
A．much easier to climb than she expected

Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學(xué)) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(電磁場(chǎng)) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.
小題1:From the passage we can learn that some people are worried because   .
A．they have evidence the use of cellphone can lead to cancer.
B．they make a fuss over cellphone use.
C．some expert has given a warning.
D．cellphones are responsible for brain tumors.
小題2:By saying “I don’t support warning labels for cellphones,” Dr Martha Linet has the idea that   .
A．the worrying is unnecessary.
B．cancer-warning labels should be on cellphones.
C．there is a link between cellphones and cancer.
D．cellphones have nothing to do with cancer.
小題3:The underlined word “underway” is closest in meaning to   .
A．started.B．kept on.C．gone on.D．in progress.
小題4:Which of the following best describes the attitude of the author towards the debate?
A．Optimistic.B．Objective.C．Disapproving.D．Casual.

Flying over a desert in an airplane, two scientists looked down with trained eyes at trees and bushes．After an hour’s flight, one of the scientists wrote in his notebook, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium".
None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth’s surface．They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a mineral search group gathered bags of tree seeds．Boxes were filled with small branches from the trees．Roots were dug and put into boxes．Each bag and box was carefully marked．In a scientific laboratory the parts of the forest trees were burned to ashes and tested．Each small part was examined to learn whether there were minerals in it.
Study of the roots, branches and seeds showed no silver．But there were small amounts of gold in the roots and a little less gold in the branches and seeds．The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.
If the trees indicated that there was no gold in the ground, the scientists wouldn’t spare money to pay for digging into the ground.
小題1:Scientists were flying over a desert or a hilly wasteland or a mountain region to _____.
A．train their eyesB．study the trees
C．look for goldD．search for minerals
小題2:The study of trees, branches and roots indicated that ______.
A．there were larger amounts of gold in the branches far from the tree trunk than in the seeds
B．there were smaller amounts of gold in the tree roots deep in the ground than in the branches
C．there were larger amounts of gold in the seeds growing closer to the tree trunk than in the seeds farther from it
D．there were larger amounts of gold in the branches than in the leaves on the ends of the branches
小題3:Which of the following is NOT mentioned as part of a tree that can help the searchers?
A．leavesB．rootsC．branchesD．seeds
小題4:Which of the following might be the best title for this passage?
A．Scientists searching for treasure with special equipment.
B．New methods of doing geological study.
C．Gold could be found in trees and plants.
D．A new method of searching for minerals.
