A
Maker of Great Violins

  Hundreds of violins are made every day. However, the finest and most sought-after violins were handcrafted by an Italian violin maker over 300 years ago. The craftsman’s name was Antonius Stradivarius, and any one of his violins is worth over $ 100,000 today.
Stradivarius, who was born in 1644,began his career as a violin maker’s apprentice(徒弟).Working on his own by 1680,he became determined to make instruments that could reproduce tones(音调)as rich as those produced by the human voice. He tested several shapes and styles for his violins until he arrived at a design that pleased him. During his career he crafted over 1,100 violins. Those still in existence have become treasured possessions.
  Unfortunately, the secret of Stradivarius’ violin died with its maker. During his lifetime Stradivarius kept his notes safely hidden; even his two sons, who helped him in his workshop, did not know all the steps in each violin’s construction.
  Through the years, many experts have offered possible explanations for the unique tone of a “Strad”. Some say it is the instrument’s shape and the combination of its parts. Others suggest that the secret lies in the special wood, which Stradivarius obtained from native Italian trees. The most widely accepted supposition is that the beautiful tone of the violins is created by the liquid that the old master used to coat his instruments. Chemists have studied and reproduced the liquid as closely as possible, and it has improved the sound of many violins. Still, no violin maker has been able to fully reproduce the tone of Stradivarius’ violins.
56.According to the passage, Stradivarius made _________.
A. hundreds of violins every day
B. over 100,000 violins during career
C. only one violin
D. more than a thousand violins during his career
57.We can conclude from the passage that Stradivarius’________.
A. notes were found by chemists
B. notes were never found
C. secrets were learned when he was an apprentice
D. notes were left to his sons
58.In this passage the word rich means ________.
 A. wealthy   B. highly amusing    C. full and pleasant   D. high and sharp
59.Another food title for the passage would be _________.
 A. how to Make Violins         B. Expensive Violins
 C. What Was Stradivarius’ Secret     D. Italian Violin Makers

  The family is larger and more varied than most people realize. It includes some animals that we normally think of as camels and some that we don’t usually recognize as camels. Everybody knows about the one-humped camel, or dromedary. And many people have heard of the Bactrian camel, which has two humps. But did you know that llamas and some other animals without humps are also camels?
  Camels have played an important role in the lives of many people for at least four thousand years. And this is mainly because camels have the ability to live in places where other large animals could never survive. In huge deserts like the Sahara, the climate can be too hot and dry for most animals. There are places where rain doesn’t fall for months, or even years. The sand may stretch for hundreds of miles, and animals may have to walk for days to reach water. The deserts of Africa and Arabia are not the only places where camels live.
  Desert winds often blow sand into the air. To protect their eyes, camels have long eyelashes that catch most of the sand. If sand gets onto an eye, a camel has a third eyelid to get it out. Like a windshield wiper on a car, this extra eyelid moves from side to side and wipes the sand away. The eyelid is very thin, so a camel can see through it. In sandstorms camels often close their third eyelid and keep walking. You might say that a camel can find its way through a sandstorm with its eyes closed.
64.We understand from the passage that_________.
A. the variety of camels is limited
B. camels refer to those animals with one or two humps
C. the camel family includes a large variety of species without humps
D. some animals without humps are also included in the camel family
65.Camels have been important to human beings for long in history mainly because__________.
A. they can go without water for a long time
B. they have special structure in their eyes
C. they can stand the heat and dryness of the desert
D. they can carry heavy loads
66.Camels can protect their eyes from the desert wind because________.
A. their eyes are specially structured
B. they have two eyelids
C. their eyelids are specially long
D. their third eyelid functions as a windshield wiper

D

  There is a range of activities which require movements of about one to four or five miles. These might be leisure activities, such as moving from home to swimming pool, tennis club, the theater or other cultural centers, or to a secondary or more advanced school; or they might be movements related with work and shopping in the central areas of cities. The use of cars which are able to carry five people at 80 mph for satisfying these needs is wasteful of space and most productive of disturbance to other road users.
  The use of the bicycle, or some more modern derivative of it, is probably worth more consideration than has recently been given to it. The bicycle itself is a remarkably efficient and simple device for using human muscular energy for transportation. In pure energy terms, it is four to five times as efficient as walking, even though human walking itself is twice as efficient as the movement of effective animals such as dogs. It is still widely used, no only in some developing countries where bicycles are major means of people and goods, but in a few richer towns such as Amsterdam in Holland and Cambridge in England.
  The bicycle neither gives enough protection from the weather nor is very suitable for carrying goods, and demands considerable muscular work to make progress against wind or uphill. It also offers its rider no protection against collisions(碰撞)with other vehicles. All these difficulties could, however, be greatly got rid of with relatively small changes in design. The whole machine could be enclosed in a plastic bubble(气泡)which would provide some protection in case of accidents.
  It would be easy to add a small petrol or electric motor. A wide variety of designs would be possible. As in rowing, we might employ the power of the arms or the general body musculature, as well as those of the legs; more muscular exercise would be good for the health of many people in cities, and a wide use of bicycle like muscle-powered vehicles would be a useful way to ensure this. It could also provide opportunities for showing-off by the young and vigorous.
67.The main idea of the first paragraph is that the car________.
A. can satisfy the demand for speed
B. causes waste of space
C. produces disturbance to other road users
D. is far from prefect for short range movements
68.More attention should be given to the bicycle as a means of transport because it is______________.
 A. a very efficient and simple device
 B. much cheaper than a car
 C. widely used in Amsterdam and Cambridge
 D. still used by rich people
69.Enclosing the bicycle in a plastic bubble would______.
A. make it easier to use
B. save muscular energy
C. provide protection from the weather
D. prevent it from colliding with other vehicles
70.Which of these is UNTRUE for the present bicycle?
A. It is far more efficient than the movement of animals.
B. It offers its rider no protection.
C. It is not very suitable for carrying goods.
D. It can hardly be improved on.

  The girls in this sixth grade class in East Pato Alto, California, all have the same access to computers as boys. But researchers say, by the time they get to high school ,they are victims of what the researchers call a major new gender(性别)gap in technology. Janice Weinman of the American Association of University Women says,“Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new way in which to understand information.
  After re-examining a thousand studies, the American Association of University Women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they used computers less often than boys outside the classroom.
   An instructor of a computer lab says he’s already noticed some difference. Charles Cheadle of Cesar Chavez School says, “Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow.”
 Six years ago, the software company Purple Moon noticed that girl’s computer usage was falling behind boys. Karen Gould says, “The number one reason girls told us they don’t like computer games is not that they’re too violent, or too competitive, Girls just said they’re incredibly boring.”
   Purple Moon says it found what girls want—characters they can relate to and story lines relative to what’s going on in their own lives. Karen Gould of Purple Moon Software says, “What we definitely found from girls is that there is no intrinsic(固有的)reason why they wouldn’t want to play on a computer; it was just a content thing.”
   The sponsor of the study says it all boils down to this: the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21st century.
71.According to the passage, girls are victims of the gender gap in technology because______.
A. they can not discover new ways to use computers
B. they have the same access to computers as boys
C. they are likely to be less comfortable with computers
D. they can only use computers for word processing
72.Girls often feel ____________.
A. bored with computer games
B. comfortable using computers
C. it hard to use computers in word processing
D. worried about using computers
73.The research on girls and computers is________.
A. based on a few recent articles
B. based on thousands of studies
C. presented by one person
D. not considered well grounded
74.The software company seems to think__________.
A. if girls had an equal chance of playing games, they would like computers
B. if the software content was changed, girls would be more interested
C. if the software was more violent, girls would like it better
D. if the characters were funny, girls would like them better
75.The gender gap needs to be closed because__________.
A. it isn’t fair that boys are allowed to use computers all the time
B. there isn’t enough money for upgrading computers
C. most of the causes may boil down to a question of money
D. the ability to use computers is important in today’s world

One Possible Version:
  I think the Five Friendlies, which will serve as the Official Mascots of Beijing 2008 Olympic Games, are all very lovely, but I really like Yingying, the Tibetan Antelope best because it is strong and runs fast. That’s what the Olympics represent and encourage. Also, Yingying comes from Tibet and it reminds us of the beauty of nature with wild animals and plants. Finally, it’s a symbol of Tibetan culture. Through this mascot we can let foreign friends know more about this part of Chinese culture.

W: Sure. Say, Randy, can you help me with the shopping? We need to get a turkey.
M: Right. Let’s get a nice big one, so we’ll have plenty of left-over to make sandwiches with.

W: Look! It’s snowing.
M: Yes, but it’s terribly cold today. I’m glad I have my overcoat on.
W: There is ice on the lake, too. We’ll be able to go skating this weekend.
M: Not if it’s too windy. Come on! Let’s go back. I’m freezing.
W: You’ll just have to learn to like it. The weather in Ottawa will be like this for the next three months.
M: Yes, I know, but I wish it were shorter here.

W: Hi, Tim. Come in. As you know, I’m meeting with all the students to talk about their class research projects. Can you tell me what you’re planning to write about?
M: Yes, at this point I’m thinking about the Indian civilization in the Southeast desert states. When I traveled there last summer, I got really interested in these people, and I’ve found some good sources of information about them. Maybe I will focus on why their civilization suddenly ended in about the year 1400.
W: That sounds very interesting, and it looks like you’ve got a good start.
M: Yes, I think I’m OK so far.
W: Good, if you need any help, come in and let’s talk about it.

W: Why weren’t you at the German class last night, Tom? Have you given up?
M: Well, no…I came back late yesterday and found John sleeping in the chair. He’d been writing report all day long and he was too tired to go out again, so we gave the lesson a miss.
W: You’ve missed quite a lot of the lessons lately, haven’t you? Are you losing interest?
M: Yes, I’m afraid so. Neither John nor I have a gift for language. People just laugh at us when we try to speak German. How did you and Jane pick it up so quickly and easily? You’ve hardly been in Germany a month.
W: It was neither quick nor easy. We’d both studied the language before we came, and we only needed to revise it.
M: Anyway, all our friends here speak English very well, so we don’t really need to learn German.

Villages in developing countries often lack many things. Books. Clean water. Electricity. These shortages are easy to see. But a different kind of shortage is not easy to see. That is the shortage of experts. Many villages have no doctors, engineers or scientists. They have no one who knows how to treat unusual medical problems or design a new energy system. There is a way to ease this problem. You can do it with computers. In the past few years, computer scientists around the world have developed what they call “expert systems”. An expert system is a special kind of commuter program. In some situations, it can take the place of a human expert.
For example, an expert medical system can help to take care of a sick person. After asking a few questions of the patient, it can tell what medicine or other treatment is needed
