Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
68. What is mainly talked about in this passage?
A. The melting of glaciers. B. Global warming.
C. The world’s weather. D. The earth’s temperature.
69. What causes global warming according to scientists?
A. Human activities. B. The nature itself.
C. The earth’s atmosphere. D. New discoveries
70. How can greenhouse gases make the globe warm?
A. They keep heat in the atmosphere
B. They let the heat go out into space.
C. They release heat into the air.
D. They can make the other gases warm.
71. From the passage we can see that global warming will bring about _________.
A. the pollution in the atmosphere B. natural disasters
C. population pollution D. the rise of glaciers

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(消费者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.
56. Most people usually use the GPS system for ______.
A. driving their cars B. telling the position C. mending the car D. supplying the sunshine
57. The farmers in Ohio use GPS to ______.
A. check if the soil is fertile in some areas B. control the rain of the place
C. water the crops if the weather is dry D. draw the map of all the crops
58. Why did Ohio farmers produce more corn?
A. Because they expanded more land to grow corn
B. Because they turned to technological advances
C. Because they used more and more fertilizer.
D. Because they supplies themselves with more money.
59. From the passage, we can know _____.
A. John Davis hadn’t expected a good harvest.
B. farmers grew less land than in the 1930s
C. improved seeds cost much more money
D. the output of corn in the same field is increased.
More perhaps than any other European nation, the Swiss have got used to looking after foreign travelers. As early as the 18th century, wealthy French, Germans and Italians were treating the country as an amusement center while, in the 19th century, it became the major holiday playground for the British nobles. Today, it attracts visitors from all over the world.
The Swiss are clear about the importance of tourism to their economy, which makes up about eight percent of the Gross Domestic Product, and helps industry greatly. Managers of hotels from all over the world go to Switzerland to learn how to do the job, and a high standard can be expected from the great majority of the country’s hotels, most of which are small and pride themselves on personalized service. Public transport is the best in Europe. Both the Swiss Federal railways and the private railways are fully electric-powered, and the total network consists of about 5,000 kilometers of track.
Under the Fly Baggage system passengers can check luggage in at 116 railway stations and have it automatically transferred to their flight. The national highway system is equally well planned, and the mountain roads offer views of some of the country’s most breathtaking scenery. Also serving the mountains is an effective system of railways and cable ways, while more than 160 passenger cars cross the lakes and rivers. Hiking in the mountains is equally popular with Swiss nationals and foreign visitors. For those who want to view the country from a great height without having to climb the mountain themselves, it is always possible to take in the view from a balloon.
６１. Compared with other European countries, Switzerland ________.
A. places more importance on entertainment
B. thinks more about foreign travelers
C. has more convenient public transport
D. has more five-star hotels

Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.
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.
５６. 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
５７. Burns are divided into different degrees according to _______.
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
５８. From the passage we learn that _______.
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
５９. It can be inferred from the passage that ______.
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

A.a fashion magazine B.a guide book
C.a book on first aid D.a section about culture in the newspaper
31st October —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.
Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.
They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.
Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”
New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.
“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”
The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.
Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”
If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.
７１ What would be the best title for the text?

7３. What is the purpose of the exploration?
A. To measure the ice cap’s thickness.
B. To study whether ice will disappear in the Arctic.
C. To make a film about the Arctic exploration.
D. To make people interested in what they are doing.
7４. It can be inferred from the passage that ________.
A. ice in the Arctic will disappear in ten years
B. the exploration will last for half a year
C. Hadow spent two years developing a kind of radar, which is about 100 kilograms
D. if there is snow on ice, satellites can’t measure the ice thickness accurately enough
7５. From the passage, we learn that ________.
A. the explorers will measure ice density every other centimeter
B. people will be able to follow the explorers and see what they are doing
C. people could go through the Northwest Passage in the 2007 Arctic summer
D. the equipment that Hadow’s team use will be tested in the United States
Sometime in the next century, the familiar early-newspaper on the front porch (门廊) will disappear. And instead of reading your newspaper, it will read to you. You’ll get up and turn on the computer newspaper just like switching on the TV. An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You’ll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events.
Most of the technology is available now, but convincing more people that they don’t need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of traditional newspapers unavoidable.
Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 to 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry.
6６. Which of the following is NOT an advantage of computer newspapers?
A. They are cheaper than traditional newspapers.
B. They are more convenient to read.
C. You can choose the kind of voice you want to hear.
D. You can easily save information for future use.
6７. Which of the following is a reason why it will take a long time to complete the changeover?
A. The technology is impossible now.
B. Computer newspapers are too expensive.
C. The popularization of computers needs a long time.
D. Traditional newspapers are easier to read.
６８. It can be inferred that journalists are against computer newspapers because _______.
A. they don’t know how to use computers
B. they think computer newspapers take too much time to read
C. they think the new technology is bad
D. they have been trained to write for traditional newspapers
６９. We can infer from the passage that _______.
A. all technological changes are good
B. new technologies don’t always replace old ones
C. new technologies will eventually replace old ones
D. traditional newspapers are here to stay for another century
７０. What is the best title of the passage?
A. Computer newspapers are well liked.
B. Newspapers of the future will be on the computer.
C. Newspapers are out of fashion.
D. New communications technology.
