An altimeter(高度计) is an instrument used in an airplane to tell the pilot how high he is flying. The altimeter used in most airplanes is a kind of barometer(气压计), which, like barometer found in ordinary homes, is a measuring instrument for air pressure. The weight of the atmosphere presses downwards everywhere. At sea level this pressure is more than 14 pounds on every square inch of the surface. The higher you go into the air, the lower the air pressure is. An altimeter measures this air pressure to show the altitude of the airplane, or, how high it is above sea level.
But the altimeter does not show how high the plane is above the ground. A plane might be flying at an altitude of 15,000 feet, but it would be only a thousand feet or so above the ground if the land in that area happened to be 14,000 feet above sea level. The pilot adjusts his altimeter to the actual sea-level pressure before leaving the airport and then corrects it in flight by new information given to him by radio. He flies high enough to be above any mountain he may pass on his course .The barometer altimeter is correct within about 300 feet.
Another kind of altimeter, the radio altimeter, makes use of radio reflection. It calculates the height of the flying plane by sending out electrical signals to the surface below and measuring the time required for them to bounce back(反弹). It is correct within 15 feet over water, but is not reliable over land. Big planes usually have both kinds of altimeter.
67. Which of the following diagrams gives the correct relationship between altimeters and barometers? (a----altimeters, b----barometers)
68. The following drawing shows a plane flying over a mountain. Which of the heights given in the drawing is given by the barometer altimeter in the plane at this moment?
69. Suppose a plane using a radio altimeter is flying 10,000 meters above highland which is 4,000 meters above sea level. What reading will be given by the altimeter?
A.10,000meters. B. 4,000meters. C.14,000meters. D. 6,000 meters.
70. Suppose a plane using both kinds of altimeters is flying over a mountainous area where the land rises and falls very abruptly (迅速地). The pilot keeps his plane steady at the same height. What kind of reading will you get on each of the altimeters?
A. The readings on both altimeters will remain steady.
B. The readings on both altimeters will rise and fall abruptly.
C. The readings on the barometer altimeter will rise and fall abruptly, while that on the radio altimeter will remain steady.
D. The readings on the radio altimeter will rise and fall abruptly, while that on the barometer altimeter will remain steady.
Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."

LONDON, England（CNN）--- The youngest person to sail solo around the world returned home Thursday from his 30,000-mile, 282-day ocean journey.
Mike Perham, 17, sailed into Lizard Point in Cornwall, the southernmost point in Britain, at 9:47 a.m., his race team said.
“It feels absolutely brilliant,” Mike told CNN by phone hours before crossing the finish line. “I'm really, really excited to be going across the line at last. It doesn't feel like long since I crossed it first.”
Mike set off on his round-the-world trip on November 18, 2008. He has been sailing his yacht single-handedly, though a support team has been sailing next to him along the way.
The teen has now achieved the title of Youngest Sailor to Circumnavigate the Globe Solo, according to the Guinness World Records.
Mike learned how to sail when he was seven years old from his father, Peter and at age 14, he sailed across the Atlantic alone.
The teenager's school --- which Mike describes as “highly supportive” of his trip --- has redesigned his coursework to fit in with his trip. It also gave him some coursework to do during “quiet moments,” according to Mike's Web site.
There haven't been many of those quiet moments. Repeated autopilot failures forced him to stop for repairs in Portugal, the Canary Islands, South Africa, and twice in Australia, according to his Web site.
Bad weather in the Southern Ocean --- between Australia and Antarctica --- forced Mike to battle 50ft waves and 57 mph winds. He said at one point, a “freak wave” picked up the boat and turned it on its side.
“My feet were on the ceiling at the time,” he told CNN. “That was a really hairy moment, and I was certainly thinking, ‘Why am I here?’ But we took the sails off and the day after I thought, ‘This is brilliant!’”
Mike describes his father as his biggest hero, always supportive of what he wanted to achieve. Peter Perham said he wasn't too worried about his son facing dangerous situations at sea, as long as he knew what to do and stayed safe.
49. Mike Perham returned to Britain in ________.
A. August B. November C. October D. September

第二部分．阅读理解（共25小题。第一节每小题2分，第二节每小题1分；满分45分）
第一节阅读下面五篇短文，从每题后所给的四个选项中选出最佳答案。
Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving. There are some aspects(方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
For those who do not particularly enjoy competitive sports — and it is especially difficult to do so if you are not good at them — there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity — physical effort on the one hand and relaxation on the other — which were the natural way of life of our forefathers.
41. Pollution, noise and stress are examples of _____.
A. the causes of unfitness B. unavoidable things in town
C. the things we can completely do away with D. bad features of modern living
42. We don’t get much out of separate sports because we _____.
A. don’t do them very often B. don’t do them actively enough
C. find it hard to get out of our armchairs D. don’t find them interesting
43. To be healthy we must _____.
A. keep fit and active B. have a sound mind
C. be active and practise Yoga D. keep fit and learn to relax
44. Our forefathers were healthy because______.
A. their way of life closely connected with both exercise and relaxation
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted
Just how far does the euro(欧元) have to fall before Europe actually becomes reasonable?
Anyone traveling to the old continent from the U.S. in recent years has learned the hard way how expensive it is. The situation has improved in the last couple of months, thanks to the Greek financial crisis. But it still has a way to go.
Alarm about Greece—and other financially unstable countries in Europe—has dragged down the euro sharply. In November, before the crisis struck, you needed about $1.49 to buy one euro. Today you need only about $1.36. That's a 9% cut.
What does that mean for you, the would-be traveler? It's a big sale.
As recently as November, when the euro was flying high, the OECD estimated that countries like France, Italy and Germany were about a third more expensive than the U.S. Not all European countries were quite as expensive for the American visitor: Greece only cost about 17% more than the US, while the Czech Republic (which is not part of the eurozone) was actually about 15% cheaper than back home.
Fast-forward two months, and the situation looks somewhat better.
At current exchange rates, places like France will still cost you about 23% more than the U.S., but cheaper countries such as Spain and Greece are now only about 6% more expensive. The Czech Republic's a fifth cheaper than the U.S.
European prices will only break even(持平) with the U.S. if the euro falls to about $1.10, says the OECD. But is it going to get there?
Greece's financial crisis may or may not be over. Members of a labor union just occupied part of the finance ministry to protest against the planned austerity(紧缩) measures. No, it doesn't inspire confidence!
Julian Jessop, chief international economist at the Capital Economics consultancy in London, sees the euro falling to $1.25 by year-end. “We still think the euro should be a lot lower,” he says. “We think the outlook for the European economy is a lot worse than for the U.S. And Greece is only a symptom of a wider problem: Does the eurozone make sense as a currency union?” If he's right, you may want to wait to change your money or book a trip.
67. In the passage the writer offers some suggestions to the travellers from______.
A．USA B．Europe C．Greece D．China
68. The underlined word “it” in the passage refers to ______.
A.the planned austerity measures
B.Greece’s financial crisis
C.the protest from a labor union
D.the decline of the euro in value
69. Julian Jessop has a negative attitude toward the euro because he thinks ______.
A.Greece’s financial crisis may not be over
B.the euro will drop to $ 1.25 by the end of the year
C.the European economy is a lot worse than the US’
D.the other European countries have a similar problem like Greece
70. The purpose of the author writing the passage is to tell the readers that ______.
A.the euro shall be further reasonably lowered
B.travelers to Europe will save less in the future
C.the economic situation in Europe is worsening
D.the Greek financial crisis influences the whole Europe
