There are three separate sources of danger in supplying energy by nuclear power.
First, the radioactive material must travel from its form of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even though, heavily populated areas.
Secondly, there is the problem of waste. All nuclear power stations produce waste that in most cases will remain radioactive for thousands of years. It is impossible to make these waste radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.
小题1:Which of the following is FALSE ?| A．It is possible that a leak or an explosion occurs at a power station. | | B．It is unusual for radioactive materials to be transported across land. | | C．The containers are likely to be broken by an earthquake. | | D．Nuclear wastes remain dangerous in most cases for many years. |
小题2:The author thinks that the ways to store nuclear wastes are ____________. | A．easy | B．impossible | C．reasonable | D．ineffective |
小题3:What do we learn from the last paragraph ? | A．The power station is a safe place. | | B．The dangers of nuclear energy can be prepared. | | C．The general public are strongly against the nuclear program. | | D．Itself, none of the three dangers is very likely to cause much worry. |
小题4: What is this passage mainly about ? | A．uses of nuclear power | | B．Dangers from nuclear power | | C．Public anger at nuclear power | | D．Accidents caused by nuclear power. |

How to improve our life? Many people think that they have to accept whatever life throws at them. They"ll say，“my destiny(命运). I cannot change it. ”
Of course not! You don"t have to suffer needlessly. Your life depends on you, not on any other external(外部的) factor.
I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is. She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, and then goes to sleep. Next day, the same routine cycle follows.
Huh! Is this what she calls “doing her best”？ She believes she has tried her best and just accepts for her heart that this is the life that has been intended for her, and that her luck can only change if God wills it. She hasn"t realized that we have to do our share of making the effort to live the life of our dreams.
Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone(unless it contributes to your success), and get your mind and body to work! Don"t expect your luck to change, unless you do something about it. If something goes wrong, don"t just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It"s not enough to think positively; you also have to act positively.
If someone"s life is in trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don"t just stand(or sit) there, do something to improve your life.
小题1:According to the woman mentioned in Para. 3, her life ________.| A．doesn"t need improving | | B．couldn"t be improved | | C．will be better some day | | D．will be worse in the future |
小题2:What does the author think of the woman"s life?| A．Passive. | B．Positive. | | C．Colorful. | D．Boring. |
小题3:Which of the following statements is the author"s opinion?| A．Your temporary problem is not discouraging. | | B．Your luck can be changed by your efforts. | | C．You can only achieve success when God wills it. | | D．You should treat yourself in the way you treat friends. |
小题4:In Para. 5, the author emphasized the importance of ________.| A．hope for the best | | B．intention to succeed | | C．positive thinking | | D．positive action |

Which animal has the fastest snapping jaw (颚)? If you"re guessing a shark or perhaps a larger animal, you"ll have to think smaller. The trapjaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second. Another way to think about this is that the ant"s jaws close at 125 to 233 kilometers per hour. That"s 2, 300 times faster than the blink of an eye.
Scientists were able to measure the amazing jaw speed using highspeed video techniques. Sheila Patek, a biologist, says the key is that the jaws have a springy (有弹性的) system, which is critical in getting explosive (爆发性的) speeds.
Consider a bow and arrow. If you try to throw an arrow with your arm, it won"t go very far. If you use a bow, elastic energy stored in the bow is released almost instantly when you release the arrow with your finger or a latch. The combination of the springy bow and latch mechanism is what makes the arrow zoom through the air.
Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move. As the ant closes its jaws, it uses them to push off the ground—all faster than the eye can see without slow motion video. A snap of the jaw can send an ant up to 8.3 centimeters into the air. That"s like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once. It would be hard for their enemies to grab just one.
People have suspected the ants used their jaws to jump for over a century, but could only prove it with today"s modern video equipment.
小题1:The fast speed of the trapjaw ant"s jaw lies in ________.| A．its light body | | B．its springy system | | C．its living environment | | D．the length of its jaw |
小题2:The passage uses “a bow and arrow” as an example to show ________.| A．how an arrow gets so much energy to fly | | B．why the trapjaw ants have springy system | | C．why the trapjaw ants jaws move so fast | | D．how a bow and arrow works |
小题3:Which of the following may amaze the scientists most?| A．How high the ants can leap by using their jaws. | | B．How quickly the trapjaw ants can move on the ground. | | C．How wonderfully the springy system in the trapjaw ants" jaws works. | | D．How quickly the trapjaw ants can grab food or enemies. |
小题4:According to the passage, the trapjaw ants" jaws keep them safe because ________.| A．they can catch their enemies easily with their jaws | | B．their jaws make them difficult to recognize | | C．their jaws help them find food easily | | D．their jaws help them escape from their enemies |

Is there something that you"ve always wanted to try but just never had the time? Well, make plans to try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos of famous landmarks. Some vacations allow you plenty of opportunities to learn.
The most difficult aspect of a learning vacation may be choosing one because the possibilities are endless. If you enjoy cooking, various companies can take you to Italy, France, Spain, Mexico or even Peru. Once there, you can learn to prepare the local cuisine(烹饪). Trips are often planned to fit in with local food festivals or special events.
The term “learning vacation” often brings language to mind. The best way to learn a language is in an environment where it"s spoken. Study Spanish, French or English. Or attempt a more unusual language like Polish, Estonian or Thai. You"ll be able to learn about the country and absorb the culture at the same time.
If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars. It"s even possible to learn the art and techniques of bull fighting while on vacation!
You can also discover our inner artist. Many places offer painting classes in different mediums. The scenic locations, of the schools offer plenty of subjects that provide inspiration for practice.
If you prefer capturing the world on film, take a photography vacation. Travel with a small group to photograph beautiful animals or scenery. You can also practise your technique on people or at historical sights.
Once you decide on a vacation, choose a company carefully. Request names of recent customers you can contact, and then ask them for an evaluation. The more you know before you go, the better prepared you"ll be. Then go out and learn something!
小题1:Why is it hard for you to decide on a learning vacation?| A．Because it is hard for you to make plans. | | B．Because the possibilities are unlimited. | | C．Because there are many good foods from abroad. | | D．Because there"re too many food festivals or events. |

Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman Empire. But when the empire broke down，this kind of tourism stopped.
In the early 17th century, the idea of the “Grand Tour” was born. Rich young English people sailed across the English Channel（英吉利海峡）.They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice（威尼斯）in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The “Grand Tour” was an important part of young people’s education—but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to” take the waters”. They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.
Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far away countries.
The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food—and tourists pay for it all before they leave home. The package tour and modern tourist industry was born.
The first travel agency in China was set up as early as 1949.But tourism did not take off until 1978.In 2002,the industry was worth 500 billion yuan and became an important part of China’s social development.
小题1:In the early times, the travelers ________.| A．all came from Roman | | B．were very young and strong | | C．had lots of money | | D．traveled by boat |
小题2:________ played the most important role in the tourism development.| A．Education | B．Money | C．Transportation | D．People’s ideas |
小题3:Modern tourism was born ________.| A．in 1949 | B．in Roman times | | C．in the early 17th century | D．in the 19th century |
小题4:The underlined phrase “take off” means ________.| A．a plane rising into the air | | B．develop very fast | | C．remove hats and clothes | | D．bring down the prices |

While football fans feel strongly angry about mistakes made by referees (裁判) because they cannot see clearly what has happened, a small German company is quietly pleased.
For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip(芯片) that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field. The world football organization, FIFA, has shown interest in the technology. It is very possible that the new technology will be used in the 2006 World Cup in Germany.
"We"ve been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The technology has performed well, and we"re pretty optimistic that it will be used at the games in Germany next year."
The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a second to a receiver network of 12 antennas(天线), placed around the field. The receivers then send information about the ball"s location to a central computer, and because it works in real time, it can immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports.
FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Germany for next year"s World Cup.
小题1:Carlos Technologies is pleased because ________.| A．football fans are angry with referees | | B．their new product can satisfy football fans | | C．their new product will have a good market | | D．they can sell a lot of football in the future |
小题2: In the first sentence in Paragraph 2,"... mistakes made by referees are the kind of advertising that money cannot buy" means ___________.| A．Carios Technologies can"t afford the high price for advertising their product | | B．Mistakes in production are also a kind of advertisement | | C．Carios Technologies has already spent a lot of money on advertising their product | | D．Referees" mistakes will be of great help for the sale of Carlos Technologies" new product |
小题3:The underlined word "feedback" probably means ___________.| A．information given back by a user | | B．advice given by someone | | C．supplying food to customers | | D．food given back by consumers |
