1、Keeping Cut Flowers
1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple fact.
2 An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.
4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.
5 Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day.

2、Arctic Melt
Earth's North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low.
Normally, ice builds in Arctic waters around the North Pole each winter and shrinks during the summer. But for many years, the amount of ice left by the end of summer has been declining.
Since 1979, each decade has seen an 11. 4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.
Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That's 38 percent less area than the average cover at that time of year. And it's a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has scientists concerned.
There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.
Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃ warmer than average and 1.5℃ warmer than the previous record high.
With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3. 3 meters thick at the beginning of the summer measured just 50 centimeters by season's end.
The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research and Engineering Laboratory in Hanover, N. H.
Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover.
Which of the following is closest in meaning to the word "build" in the first sentence of the second paragraph?
【单选题】

A.construct

B.extend

C.create

D.expand

正确答案:D

答案解析:本句意思为“每年冬天北极附近的北冰洋开始结冰”，build为“结冰”的意思，expand有“容积扩张”的意思，所以与build相符；而construct为“修筑、建筑”的意思，所以不能选。

3、An Intelligent Car
Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?
There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car's left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver's "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line for the intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car.
What is the virtual driver's best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world's best driver at least needs one second to react. Besides, when he takes action, he needs one more second.
The virtual driver is really wonderful. He can reduce the accident ______. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways.
【单选题】

A.count

B.amount

C.digit

D.rate

正确答案:D

答案解析:直接借助空白所在的局部搭配（事故……）判断答案是D（事故发生率）。

4、Budget
A budget is a spending plan. It can help you spend money wisely. It can do this by cutting out wasteful spending. Of course, preparing a budget takes planning, and following a budget takes will power. Your budget should meet your family's needs and income.
The first step in creating a budget is to set your goals. What does your family need and wants. You must know this to work out the details of the budget. Keep goals realistic, in terms of income available. Then decide which goals are the most important.
The next step is estimating family income. Before you can plan wisely, you need to know how much money you have to spend! Write down all the money you expect to receive (wages, savings, interest, etc.) during the planned budget period.
After you have calculated how much money will be available, it is time to estimate expenses. List all of your family expenses.
If you are not satisfied with what you got for your money, look carefully at your spending. Studying your records will show where overspending has occurred. It will also point out poor buying habits.
It is also a good idea to set aside a small amount of money for emergencies. Every family has small emergencies: a blown tire, a broken device, or the need for minor medical care.
According to the passage, what is the advantage of a budget?
【单选题】

A.It can help you set your goals clearly.

B.It can help you save a lot of money.

C.It can help you get rid of poor buying habits.

D.It can help you spend money in a reasonable way.

正确答案:D

答案解析:第1段第2句“It can help you spend money wisely”（预算帮助你聪明地花钱），也就是说理智地消费( spend money in a reasonable way)。

5、Will We Take Vacation in Spaces?
When Mike Kelly first set out to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."
According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits for a two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) set to actor by 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "
This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support or return trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. And that doesn't include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entire group of entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive for the little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space's prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can't be too prepared, for a trip to that galaxy far, far away.
For those who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite.
Space Adventure in Arlington has taken 130 deposits totaling $98,000 for a two-hour space tour.
【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:B

答案解析:第2段第2句的意思是：每人交100万美元的定金，而不是总共98 000美元，从这句话中可以看出历时两个小时的太空旅行计划在2005年，该旅行是试验性的，并且在一定程度上令人质疑。因此题干的说法是错误的。

6、Some Unusual Celebrations
Some holidays are well - known all around the world. Among them are New Year's Eve celebrations. Also common are days in honor of love and friendship, like Valentine's Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks and government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.
Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool's Day, for example. No one knows when or why it began. Today it is celebrated in many countries—France, England and Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?
Dyngus Day in Poland seems strange too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.
Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.
August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. They bring him back to town, put a crown on his head, and make him king for three days.
There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. _____
Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.
【单选题】

A.They bring him back to town, put a crown on his head, and make him king for three days.

B.Some of the days people celebrate, however, are less serious.

C.That is supposed to be Toothache Day.

D.Then begins the world-s biggest food fight.

E.Some people have fun imagining new holidays.

F.Jokes are supposed to be funny, but these jokes do not make everyone laugh.

7、A Great Quake Coming?
Everyone lives in San Francisco knows that earthquakes are common in the Bay Area and they can devastate. In 1906, for example, a major quake destroyed about 28000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It's bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth's crust (地壳) slide past each other. When these pieces slip, the ground shakes.
To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.
One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.
At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.
Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.
New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city's buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it's not a matter that whether "the Big One" will hit here. It's just a matter of when.
Earthquakes rarely happened in San Francisco before 1906.【单选题】

9、Sharing Silence
Deaf teenagers Orlando Chavez and German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.
Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten.
"We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn't know I was deaf and I was different."
"Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn't understand us and we didn't understand them. But we've all grown up together, and today, I'm popular because I'm deaf. Kids try to communicate with me."
Some things are very difficult for the two boys. "We can't talk on the phone, so if we need help, we can't call an emergency service," German signs. "And we can't order food in a drive - thru."
Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.
They got their jobs through a "workability" program, designed for teenagers from local schools with different types of learning disabilities.
German has worked in the supermarket since August, and Orlando started in November.
"The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we've learned a lot and we're getting better."
The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute for the Deaf in New York.
Both boys are happy to ______.【单选题】

A.design programs tor the deaf

B.work at the National Technical Institute for the Deaf

C.help students with learning disabilities

10、One Good Reason to Let Smallpox Live
It's now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?
In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). And the last "official" stocks of live Virus bred mistrust of the US and Russia, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines(疫苗). So once again there's a good reason to the virus, just in keep the disease puts in a reappearance.
How do we _____ with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that's open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn't mean the idea is rejects. If the virus is useful, then let's wrong it the servant of all humanity make not just a part of it.
