Theodore, manager of the Paradise Hotel,told a middle-aged couple that they would have to leave the hotel
after just one night.The couple,visiting from Texas,had booked a room for eight nights.
“They wanted a sterile (消毒了的) environment,”Theodore said,“They should have rented a room in a hospital,maybe an operating room.This hotel is clean,hut it isn't that clean.”

2.Maja Kazazic looked closely down into the aquarium(水族馆). For two years, she’d been watching the injured dolphin named Winter swim around the tank.. From a distance, the dolphin seemed approachable enough. Still,
as Kazazic prepared to jump into the water, a little panic gradually came into her excitement.
The young woman eased herself into the pool. Despite her fear, she felt strong wearing her new leg. She was ready to make good on a promise from long ago.
In second grade in M ostar, Yugoslavia, Kazazic’s five-year-old cousin, Jasmina, died of leukemia(白血病). Kazazic swore that she would honor the little girl by swimming with a dolphin, an animal they both adored. “Jasmina never got the chance to do it,” says Kazazic, 32, “so I decided that someday I’d do it for her.”
In 1993, during the Bosnian civil war, 16-year-old Kazazic was badly injured. Her left leg was cut off just below
the knee and was brought to the United States for treatment. A few months later, Kaz azic received her first artificial leg. Because her right leg was also damaged, walking was still very painful. Nonetheless, she managed
to graduate from a local high school.
After receiving a BA in psychology, she moved to Florida’s Gulf Coast. She liked wa tching the dolphins play at
the aquarium. A young dolphin, Winter, who had lost her tail in a crab trap, caught Kazazic’s eye: “She swam more like a shrimp(虾) than a dolphin.”
After one doctor’s visit, trainers fit Winter with a high-tech tail. When it was done, Winter swam away fast.
Kazazic was impressed. She approached the trainers, who put her in touch with the inventors. Within ten days, she had a new leg and she could walk without pain again.
Eight months later, Kazazic was ready to keep the promise s he had made in honor of Jasmina. “After being in a war zone, this should be a piece of cake,” Kazazic said as she lowered herself into the tank. She held out a hand to Winter, who approached cautiously, and then moved away. After a few minutes, the dolphin let Kazazic move her hand gently over her back. The two started an hour-long swim around the pool. When Kazazic climbed out, her parents hugged her. She would have shouted with joy had she not been aware of dolphins’ sensitivity to noise. Instead she quie tly said, “I felt I owed somebody something, and now I’ve paid my debt.” Out in the
parking lot, she got into her car and shouted loudly and happily all the way.
59. Which is the correct order of the following events?
a. Kazazic was brought to the USA for treatment.
b. Kazazic’s five-year-old cousin, Jasmina, died of leukemia.
c. Kazazic swam with a dolphin named Winter.
d. Kazazic’s left leg was cut off below the kne
e.
e. Kazazic had a new leg and could walk without pain.
A. b,d,c,a,e
B. b,d,a,e,c
C. d,a,e,c,b
D. b,a,d,e,c
60. Which of the following sentences BEST indicates Kazazic is a woman who keeps her word?
A. Despite her fear, she felt strong wearing her new leg. (Paragraph 2)
B. … “so I decided that someday I’d do it for her.” (Paragraph 3)
C. “I felt I owed somebody something, and now I’ve paid my debt.” (Paragraph 7)

3.You can love them or hate them, but no matter which tourist des tination you visit, chances are that you’ll see someone with their head buried in a Lonely Planet guidebook.
Lonely Planet is one of the world’s largest travel guide brands, publishing more than 500 different guides in eight languages. The popular brand also produces television shows, websites and podcasts(播客)all devoted to travel. Some people praise Lonely Planet books because they make traveling easy and affordable. They also save time and make sure you don’t miss the best things.
They also provide the reviews of hostels(旅店), hotels, restaurants and ticket information about your destination. This can be great if you’re a nervous traveler, or if you haven’t traveled by yourself before. If you’re in a country where you don’t speak the language, sometimes there’s nothing better than getting into a taxi and opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that’s cheap and clean, with friendly staff and cold beer.
But o thers criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take the fun and spontaneity(自发性)out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen. They also regret that if you follow a guidebook, you’ll end up doing the same thing and having the same experience as everyone else. You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.
Another criticism of travel guides is that they have a large impact on local communities. For example, some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.
63. The Lonely Planet guidebook can bring you the following advantages EXCEPT that __________.
A. you can speak a foreign language when opening a guidebook
B. you can easily find a nice place to stay in a strange city
C. it provides lots of useful information about your destination
D. it can help you save time and money when traveling
64. People criticize the guidebook because __________.
A. it is not as useful as most travelers expect
B. tourist destinations will be crowded if everyone follows the same route
C. travelers may not get the chance to have unexpected adventures
D. local people keep modern lifestyles under its influence
65. What do we know about the Lonely Planet guidebook from the text?
A. It’s a world-famous brand only producing guidebooks for travelers.
B. It’s very useful to a person who’s nervous about touring an unfamiliar place.
C. It’s very useful to a tourist who likes to repeat others’ experiences.
D. It is loved by all travelers because of the convenience it brings to travelers.
66. Which of the following best shows the structure of the text? (①—⑦ stand for Paragraph 1
—Paragraph 7 )
A. ①
B. ①
C. ①
D. ①

5.For some time past it has been widely accepted that babies----and other creatures----learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的) “drive” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
Paousek began his studies by u sing milk in the normal way to “reward” the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children’s response in situation where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “switched on a display of lights---- and indeed that they were able to learn quite complicated turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek’s light display was place d directly in front of the babies and he made the interesting observation that sometimes they would turn back to watch the lights closely although they would “smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a primary human urge to make sense of the world and bring it under intentional control.
72.According to the author, babies learn to do things which ____.
A. are directly related to pleasure
B. will meet their physical needs
C. will bring them a feeling of success
D. will satisfy their curiosity
73.Papousek noticed in the studies that a baby ____.
A. would make learned response when it saw the milk
B. would carry out learned movements when it had enough to drink
C. would continue the simple movements without being given milk
D. would turn its head to right or life when it had enough to drink
74.In Papousek’s experiment babies make learned movements of the head in order to ____.
A. have the lights turned on
B. be rewarded with milk
C. please their parents
D. be praised
75.According to Papousek, the pleasure babies get in achieving is a reflection of ____.
A. a basic human desire to understand and control the world
B. the satisfaction of certain physiological needs
C. their strong desire to solve complex problem
D. an important human urge to display their learned skills

More than a century after its discovery, Alzheimer’s disease is still destroying people’s brains. The cause remains unknown.
Alzheimer’s disease is the most common disability or mental sickness called dementia. Dementia i s the loss of thinking ability that is severe enough to interfere with daily activities.
About thirty million people around the world have Alzheimer’s disease. In the United States, more than five million people are said to suffer from this slowly increasing brain disorder (疾病).
Alzheimer’s disease generally develops differently in each person. Yet some early signs of the disease are common. The victims may not recognize changes in themselves. Others see the changes and struggle to hide them.
Probably the most common early sign is short-term memory loss. The victims cannot remember something that happened yesterday, for example. Also, the victims have increasing difficulty learning and storing new information. Slowly, thinking becomes much more difficult. The victims cannot understand a joke, or cannot cook a meal, or perform simple work.
Another sign of the disease is difficulty solving simple problems. The patients might not know what to do if food on a stove is burning. Also, people have trouble following directions or finding their way to places they have known all their lives.
Yet another sign is struggling to find the right words to express thoughts or understand what is being discussed. Finally, people with Alzheimer’s disease seem to change. Quiet pe ople may become noisy. They may easily become angry and lose their ability to trust others.
Alzheimer’s disease affects memory and personality. The victims slowly lose their ability to deal with everyday life.
Victims of Alzheimer’s disease do die from its effects or conditions linked to it. But death may not come for many years.
Patients cannot fully recover from the disease. But many can be helped by medicine. That is especially true if the disease is found early.
Title Alzheimer’s disease: The World’s Most Common Form of Dementia
★ Short-term memory loss.

★ The victims have difficulty in thinking.
