Houses fall down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That’s what some villagers in Alaska have been asking themselves recently and scientists think they know why. Warmer temperatures may be causing Alaska’s frozen ground to thaw (解冻).
About 85 percent of Alaska’s land surface has permafrost (永久冻结带). Permafrost supports the ground above it—including trees, houses, and roads. But why is the permafrost thawing?
Some scientists say that human-caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals.
The collapsing (倒塌) is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost.
The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house-moving companies have been very busy.
“Melting permafrost can also destroy trees and forests,” Walters said. “When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp (沼泽), and animals which need the forests will have to move elsewhere.”
“The melting could cause severe problems.” Walters says, “This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now.”
1.The main reason why permafrost is thawing is that ______.
A. the temperature in Alaska is rising
B. people in Alaska don’t take care of permafrost
C. too many houses are built on permafrost
D. people in Alaska polluted permafrost
2.The following are the results of melting permafrost EXCEPT ______.
A. holes form in the ground
B. a forest will be turned into a swamp
C. some animals have to go elsewhere
D. more water will be needed by people and animals
3.Which of the following is NOT true according to the passage?
A. When permafrost melts, houses will fall down.
B. House-moving companies are busy because their houses are in danger.
C. To stop permafrost melting is a very difficult problem.
D. Most of Alaska’s land surface has permafrost.
4.Which of the following can be used as the best title of the passage?
A. Alaska—A Frozen Land B. Pollution and Global Warming
C. Is Alaska Sinking? D. Alaska Is Polluted

Valcamonica has one of the largest collections of rock drawings in the world. There have been about 200,000 figures and symbols carved into the rocks over a time period of approximately 8,000 years. Valcamonica's pictures show various scenes and are connected through common themes like magic, war, navigation and agriculture.
The rock drawings discovered in Valcamonica were the first prehistoric symbols of their kind recognized anywhere in the world. UNESCO first recognized the drawings in 1979 when about 140,000 were discovered, however, since then many more have been uncovered.
These drawings are spread all across the valley. The carvings began to taper off during the Iron Age and fewer appeared after that. The last period has been attributed to (归功于……) the Camunni people. Still there are drawings that have been identified as being from the 19th century. Many of these were created using the technique of engraving (雕刻).
Some of the figures discovered in Valcamonica have been superimposed (叠印) without any order, but in most cases they appear in logical orders and also explain the relationship between each picture or symbol to tell a story.
The first known modern report of the rock carvings was in 1909 when Walther Laeng happened upon two decorated rocks in Capo di Ponte. Scholars only took interest in the drawings in the 1920s. More rocks with engravings were soon found in the areas nearby and research into their history began. In the 1930s comprehensive study campaigns were undertaken.
It was after the Second World War that the cataloging and mapping of the engravings began. This task was taken up by various teams of experts from Italy and other countries that were led by Laeng. In 1955 preservation work on the rocks began.
In 1968, a large series of conferences were held where scholars from all over the world met to discuss the rock drawings, which give us some idea of what various societies of the past might have been like.
1.What do we know about Valcamonica's pictures?
A. They tell a long whole story.
B. They are interrelated in some ways.
C. They were carved 8,000 years ago.
D. They were first discovered in 1979.
2.The underlined part “taper off” in Paragraph 3 can best be replaced by “_____”.
A. turn up B. go up C. die out D. stand out
3.What is Paragraph 5 mainly about?
A. The history of the rock drawings.
B. The features of the rock drawings.
C. The discovery of the rock drawings.
D. The formation of the rock drawings.
4.Studies of the rock drawings _____.
A. show us the development of art
B. started after the Second World War
C. were conducted by scholars from UNESCO
D. help us know something about societies of the past

One day, a patient came to see me. He worked as a waiter in a restaurant and his problem was acid reflux (胃酸倒流), a disease that influences as many as 40 percent of Americans, a marked increase in recent years. Reflux can lead to esophageal (食道的) cancer, which has increased by about 500 percent since the 1970s. The drugs we use to treat reflux don’t always work and may even increase the risk of developing cancer when used long term.
What is responsible for these worrying developments? For one, our poor diet, with its huge increases in the intake of sugar, fat, soft drinks, and unhealthy foods. But another important fact has been overlooked: dinnertime. Over the past twenty years, the time of my patients’ evening meals has become later and later. Dinner — already pushed back by longer work hours — is often further delayed by activities such as shopping and exercise.
In my experience, the single most important treatment for reflux is to avoid late eating. A patient with reflux came to see me because her father and uncle died of esophageal cancer, and she was afraid of getting it too. Her nightly routine (常规) included a 9 p.m. dinner with at least two bottles of red wine. The reflux was serious, and changes were needed.
She listened, then did not come back to see me for a year. “For the first two months, I just hated you,” she told me, “and for the next two months, I was having some trouble eating. I guessed I was going to die of esophageal cancer.” Then she added, “You know, we’re the reason that it’s not so easy to get 6 p.m. reservations (预约) at the good restaurants anymore.”
To stop the increase in reflux disease, we have to stop eating at least three hours before bed. As for my waiter patient? I told him to eat dinner before 7 p.m. Within six weeks, his reflux was gone.
1.The disease the waiter caught is _____.
A. on the rise
B. easy to control
C. unusual in America
D. the most dangerous cancer
2.What does the underlined word “overlooked” in Paragraph 2 mean?
A. Talked about a lot.
B. Paid no attention to.
C. Carefully looked into.
D. Taken into consideration.
3.Why did the woman patient hate the author?
A. He spoke of her dead father and uncle.
B. He asked her to change her eating habits.
C. He couldn’t find a way to deal with her problem.
D. He couldn’t make her healthy again within a year.
4.The author writes the text to tell us _____.
A. not to work late at night
B. to avoid eating at restaurants
C. unhealthy foods cause cancer
D. the danger of eating late at night
