We can make all the jokes we want about taking baths ourselves, but if we are ill in bed and can't get up, we'll be thankful to the nurses who help us get clean. While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy (同情) and patience to do so.
Yet those who attended the International Conference on Intelligent Robots and Systems last month were introduced to Cody, a robot that can bathe human beings.
The robot has a base that can be turned to all directions, two humanlike arms, and movable wrists (腕). It uses a camera to locate parts of the human body. It then uses bath gloves to clean with a little pressure.
The robot was designed at the Georgia Institute of Technology. Charles Kemp of the Healthcare Robotics Lab is the senior researcher for the project. In a test run, Cody was able to remove 96% of a test subject's dirt—not bad for a robot.
But don't go asking for Cody yet—he's still a model. Yet researchers believe that one day Cody may take the place of nurses for this task. Researchers say that Cody will give patients dignity and protect their personal information. I suppose that would depend on the patient. I'm not sure whether a robot using a camera would make me feel very dignified.
Even so, I can appreciate the need. We don't have enough nurses to go around, and those places that are the most shorthanded, for example, nursing homes, are those that have the most patients who are unable to bathe themselves. Still, before I get there, I hope they think of a better way to solve the problem.The writer thinks bathing others must ________.
| A.be a lot of fun |
| B.make you feel thankful |
| C.take a lot of patience |
| D.make you feel dignified |

| A.Why and where Cody was designed. |
| B.What Cody looks like and who designed it. |
| C.What Cody can do and where it will work soon. |

| A.Cody can bathe patients better than a real nurse can |
| B.robots like Cody are being produced in large numbers right now |
| C.Cody can take the place of nurses completely in hospitals |
| D.researchers think Cody can protect patients' personal information |
There is a need for Cody because ________.
| A.people are becoming lazier |
| B.it can bring down the cost of nursing |
| C.there are not enough nurses |
| D.there are too many nursing homes |
In the writer's opinion, Cody is ________.
| A.acceptable but not perfect |

If your idea of a good time is to sleep in a hut, carry your own rubbish, and eat insects and wild animals, then ecotourism may be just for you. But is it also for people who want to fly over a rainforest sky before checking into a comfortable and expensive hotel in the middle of a national park? Whatever ecotourism is, it is hot--perhaps too hot for its own good.
The World Tourism Organization claims that the industry looked after 592 million travelers last year who spent $423 billion, and of all the types of tourism, ecotourism seems to be the fastest growing. By the broadest measure -- a trip with some sort of nature or wilderness element -- ecotourism already accounts for perhaps a third of these travelers. On a stricter definition favored by the Ecotourism Society, it is “responsible travel that preserves natural environments and keeps up the well-being of local people,” which accounts for no more than 5% of tourism.
Ideally, ecotourism helps both people and nature. Before the disastrous civil war, Rwanda’s Mountain Gorilla Project was one such model. Visits to the gorillas were limited, local guides ensured good behavior or on the part of the humans, and the high admission charge - $170 a day -- paid for salaries and presentation of the gorillas’ living areas. As this made the gorillas worth more alive than dead, poaching (偷猎) decreased. As another example, preservation Cooperation, Africa’s largest ecotour operator, uses only local labor, buys products 5om local farmers, and supports building projects: such as clinics and schools. This contribution to social advance is also good business sense. Projects from which local people benefit directly are less likely to be affected by poaching and theft.
Ecotourism’s biggest problem is labeling. Going on an eco-tour is no guarantee of good ecology. So far, only Australia has an official system to grade tour operators and tourist attractions on the basis of their “greenness”. Another issue is how eco-tourists damage the environment. Dolphin-feeding, for instance, is innocent and enjoyable, but after too many free meals, the dolphins forget how to catch their own dinners.
Keeping prices high is one way to limit enthusiasm. But measuring the effect of ecotourism on human environments is trickier. It is common, for villagers to see ecotourism as a source of new income. Hence, the very tourists who venture in search of traditional cultures end up breaking them up. As ecotourism becomes more popular, it will finally threaten the very things that are good for business.According to the passage, ecotourism may _________.
| A.harm its own purpose by becoming too popular |
| B.save the environment by becoming more popular |
| C.harm its own purpose by becoming less popular |
| D.save the environment by becoming less popular |
Within the tourism industry as a whole, ecotourism _____________.
| A.has no single, clear definition that would satisfy everybody |
| B.has expanded less rapidly than other types of tourism |
| C.claims that no comfortable hotels should be used by tourists |
| D.most often has a negative effect on local culture |
Rwanda’s Mountain Gorilla Project is a good example because ___________.
| A.tourists were free to visit the gorillas whenever they wanted to |
| B.local people’s attitudes toward animals were not affected |
| C.the gorillas were protected from both tourists and local people |
| D.the gorillas’ living area was modernized because of the high admission |
_________ most directly benefits the local community.
| A.Rwanda’s Mountain Gorilla Project | B.Preservation Corporation |
| C.Australia’s grading system | D.Dolphin-feeding |
It was the afternoon of December 24, the day before Christmas; and as the newest doctor in our office, I had to work. The only thing that brightened my day was the beautifully decorated Christmas tree in our waiting room and a gift sent to me by a fellow I was dating — a dozen long-stemmed red roses.
As I was cleaning my office, I was told a lady urgently needed to speak with me. As I stepped out, I noticed a young, tired-looking woman with a baby in her arms. Nervously, she explained that her husband — a prisoner in a nearby prison — was my next patient. She told me she wasn’t allowed to visit her husband in prison and that he had never seen his son. Her request was for me to let the boy’s father sit in the waiting room with her as long as possible before I called him for his appointment. Since my schedule wasn’t full, I agreed. After all, it was Christmas Eve.
A short time later, her husband arrived — with chains on his feet and hands, and two armed guards as bodyguards. The woman’s tired face lit up like our little Christmas tree when her husband took a seat beside her. I kept glancing out to watch them laugh, cry and share their child. After almost an hour, I called the prisoner back to my office. The patient seemed like a gentle and modest man. I wondered what he possibly could have done to be held under such conditions. I tried to make him as comfortable as possible.
At the end of the appointment, I wished him a Merry Christmas-a difficult thing to say to a man headed back to prison. He smiled and thanked me. He also said he felt saddened by the fact he hadn’t been able to get his wife anything for Christmas. On hearing this, I was inspired with a wonderful idea.
I’ll never forget the look on both their faces as the prisoner gave his wife the beautiful, long-stemmed roses. I’m not sure who experienced the most joy — the husband in giving, the wife in receiving, or myself in having the opportunity to share in this special moment.What can be inferred from the first paragraph?
| A.The writer was a newcomer to her office. |
| B.A fellow sent her a dozen red roses as Christmas present. |
| C.She was in low spirits because she had to work before Christmas. |
| D.She was at work with a light heart. |
The young woman came to the writer’s office for the purpose of .
| A.having her baby examined |
| B.giving her husband a chance to make his escape |
| C.having her husband examined |
| D.getting a chance for her family to get together |
The underlined part in paragraph 3 most probably means “”
| A.to be sent to hospital | B.to be separated from his family |
| C.to be comfortable | D.to become a prisoner |
What does the writer learn from the story?
| A.The wife experienced the most joy in receiving |
| B.An act of kindness can mean a lot |
| C.The prisoner was treated with mercy |
| D.Whoever breaks the law should be punished |
In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods.
Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries, Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many “sales” in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to “get your money’s worth” when you shop? Perhaps the best advice is: Don’t hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices.
There is a great variety of shops in the United States, ranging from very large stores called “department stores” to very small shops. There are “discount houses” offering goods at low prices, and “dime stores” specializing in a wide range of inexpensive items.
Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products.
If convenience isn’t as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don’t offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn’t deliver purchases.
Another popular shop is the “dime store”. No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.Where can we most probably read this passage?
| A.In a research paper. | B.In a science report. |
| C.In a geography book. | D.In a travel magazine. |
Why can discount houses offer goods at lower prices compared with department stores?
a. They have fewer employees.
b. They have larger quantities of goods.
c. They offer fewer services.
d. They don’t provide delivery service.
| A.a b c | B.a b d | C.a c d | D.b c d |
What’s special about dime stores?
| A.They sell lots of goods at a small profit. |
| B.They make big profits by selling some goods. |
| C.They provide goods with a price lower than 50 cents. |
| D.They provide goods ranging from bargains to expensive ones. |
Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis(绿洲), from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.
When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.
Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.
Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________________.Ken Levin asked Argutel to walk to the north in order to ________.
| A.prove that people could walk out of the desert see |
| B.how far away Bissel was to the edge of the desert |
| C.tell people not to walk in circles |
| D.show Argutel was a great person |
According to the passage, Ken Levin ________.
| A.knew Argutel before he came to the village |
| B.came to Bissel to do experiments on behalf of his college |
| C.became the first man to walk out of the desert from Bissel Village |
| D.taught Bissel villagers knowledge of the North Star when he first arrived |
It can be inferred from the passage that ________.
| A.Ken Levin didn’t walk south because it would take more days |
| B.the use of a compass was necessary to walk out of the desert |
| C.tourism in Bissel has been greatly developed and improved |
| D.Argutel became the leader of Bissel after his return |
Which of the following can most probably be found at the base of Argutel’s statue?
| A.A new life starts from the fixed direction. |
| B.Where there is a will, there is a way. |
| C.A long journey starts with the first step. |
| D.Two heads are better than one. |
