In old times,  man considered lightning to be one of the great mysteries(神秘事物)of nature.  In fact a single flash of lightning 1. 6 kilometers long has enough electricity to light one million lamps.    
The American scientist, Benjamin Franklin, was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above. It happened in 1752. In the same year, he also built the first lightning rod(避雷針)to protect buildings from being struck by lightnings.    
Modern science has discovered that lightning is very strong and powerful. A lightning between a cloud and the earth may be as long as 13 kilometers, and travels at a speed of 30 million meters per second.  Scientists have the opinion that there are about 2, 000 million flashes of lightning per year. In the United States alone, it kills almost one person per day.     The safest place to be in during an electrical storm is a closed car. Outside, one should go close to low ground for cover and not stop under a tree. Also one should stay out of water and away from metal fences. Inside a house people should keep away from open doorways and windows and not touch wires or metal things.

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.
For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as danger. With good guides, some education, and a few precautions(預(yù)防 ), the wilds of the Internet can be safely navigated. “Kids have to be on-line. If we tell our kids they can’t be allowed to surf the Internet, we’re cutting them off from their future,” said an expert.
Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can’t be wholly reliable(可靠 ), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet.
A few other tips:
—Do not put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
—Ask your child what he or she has been doing and about any friends they make on-line.
―Tell your child not to give on-line strangers personal information, especially like address and phone number.
And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.
小題1:What is the best way to protect children from improper material?
A．To talk to the children and persuade them to tell right from wrong.
B．To be nearby when the children are surfing the Internet.
C．To fix a content screener on the computer.
D．To buy some search engines for children.
小題2:Which of the following statements is true according to the passage?
A．Surfing the Internet is the best way of educating children.
B．Using a content screener is most reliable for keeping children from having ways to the Internet.
C．Searching engines can help children to select materials fit for them.
D．Children’s not having chances to go to the Internet may have effect on their progress.
小題3:According to the passage, we can infer that ____.
A．softwares that are fit for children who want programming
B．the Internet contains a lot of harmful sites
C．the Internet will be protected by law
D．a(chǎn) child who is on-line is in danger
小題4:What does the passage tell us most?
A．EducationB．Good guidesC．PrecautionsD．Software

Whales live in the ocean, but they are not fish. They are warm-blooded mammals and must have air to breathe. The babies are born alive and drink milk from the mother's body. It took millions of years for the whale to develop as it is today.
Every spring groups of whales swim hundreds of kilometers to warm places to bear their young. Each group goes to the same place every year. The mothers take very good care of their babies. The fully grown whales are very gentle and playful with each other, and with humans. They “talk” to each other with a high noise that  sounds beautiful. This“talking” can be heard for more than 300 kilometers in open waters.
Yet humans kill over a hundred whales a day. They kill them to make whale oils and a lot of other things. Killing them is a modern business with modern machines and even harpoons( 魚叉炮) that explode( 爆炸) inside the whales. A whale dies very slowly and in great pain. Some ships kill every whale they can find, even the mothers and babies. Then there are no young whales to grow up or to bear more young.

Hi！Have you ever suddenly felt that someone you knew was in trouble—and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感覺知覺).
　　ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
　　Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.
　　There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example—one of hundreds of dreams that have come true.
　　A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more."
　　Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
　　Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
小題1:According to the passage, the author believes that the sixth sense is ________.
A．in existence B．imaginative C．not real D．impossible
小題2:ESP lets people know _________.
A．a(chǎn)bout events before they happen
B．a(chǎn)bout events after they happen
C．a(chǎn)bout events that are happening some distance away
D．A and C
小題3:In the last paragraph the underlined word "coincidences" probably means _______.
A．things that may not happen
B．things that happen in a dream
C．things that must happen
D．things that happen by accident
小題4:This article is mainly about ________.
A．the human dreamB．the sixth sense
C．the human mind D．a(chǎn) crowded bus

There is a lot of misunderstanding about studying. Most students have not been taught the principles behind really effective working. Imagine a graph showing the amount a person learns against the number of hours he works in a day. If he doesn’t do any work, he learns nothing (point 0). If he does an hour’s work he learns a certain amount (point 1). If he does two hours’ work he learns about twice as much (point 2). If he does more work he’ll learn still more (point 3). However, if he tries to do twenty-three and a half hours’ work in a day, he will be so tired that he’ll hardly remember anything: what he learns will be very little (point 4). If he did less work he’d learn more (point 5).
Now whatever the exact shape of the graph’s curve(曲線), made by joining these points, it must have a high point. Point “X” is the very maximum anyone can learn in the day. And this represents the optimum(最適度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(勞累). Fatigue is an absolutely real thing; one can’t escape it or ignore it. If you try to ignore it and press yourself to work past the optimum, you will only get on this downward slope and achieve less than the best – and then become very tired and lose your power of concentration.
The skill in being a student consists of getting one’s daily study as near the optimum point as possible. I cannot tell you what the optimum is. It differs with the type of work, it differs from person to person, and even in the same person it varies from week to week. You must try to find your own. Every day you study, bear this principle of the optimum in mind. When you feel yourself getting fatigued, if you find yourself reading the same paragraph over and over again and not taking it in, that’s a pretty good sign you’ve reached your highest point for the day and should stop. Most ordinary students find their optimum at five hours a day. Yours may be a little more or a little less – but if you get in five hours’ good work a day, you will be doing well.
Now, what are you doing with yourself when you aren’t working? Before examinations some students do nothing at all except sit in a chair and worry. Here is another misunderstanding. People often think that the mind works like the body; it does not. If one wanted to save one’s physical energy in order to cut the maximum amount of firewood, one would lie flat on a bed and rest when one wasn’t chopping. But the mind cannot rest. Even in sleep you dream, even if you forget your dreams. The mind is always turning. It gets its relaxation only by variety. That is what makes the mind rest.
When you’ve finished your optimum number of hours you must stop. You must not then sit around in the chair thinking about the work – that only tires without any learning. You must get out and do something. It doesn’t matter what – anything so long as you are actively doing something else but work.
小題1:According to the passage, _______.
A．the longer you study every day, the more you will learn
B．you’ll achieve better learning results if you work three hours every day
C．the less work you do, the better you will learn
D．your work efficiency will decrease once you exceed a certain point of work
小題2:Fatigue can result in ________.
A．loss of memoryB．a(chǎn) need for relaxation
C．a(chǎn) lot of anxietyD．loss of concentration
小題3:The passage tells us that a person’s optimum number of working hours _______.
A．follows a regular pattern with each individual
B．changes regularly from week to week
C．can be partly determined by the sort of work he is doing
D．should be determined before he gets too tired
小題4:The only way the mind can relax is by ________.
A．doing a variety of things in turn
B．not thinking about anything
C．turning continuously
D．getting oneself in a state of fatigue
小題5:After you have reached the optimum point of study in a day, you should ________.
A．lie in bed and rest
B．do something else actively
C．do some physical labor
D．stop thinking about your studies

Parents have widely different views on the problem of pocket money. Four new fathers were asked this question and this is how they answered. 
Ashish Khanna: Although many argue that pocket money helps develop children’s sense of value, I don’t agree. I wouldn’t give my child any pocket money. First of all, I never got pocket money and I seem to have a good value for money. If my child ever needed something and I felt it was a reasonable (合理的) request, I would buy it for him.
Sharad Sanghi: No, I wouldn’t give my child pocket money because I don’t want to create the perception (觀念) of “her” money and “my” money. Besides, if I refuse to buy her something that I think is bad for her, she may buy it with her pocket money on the sly. In this way, I would lose control over my child’s requests. I feel it also encourages children to care more about money than anything else. I don’t want my child to start judging other children by the amount of money or pocket money they have.
Rakesh Shah: Yes, I would give my child pocket money because I feel that children should learn to spend money properly. I will give him a fixed amount every month and if he spends the money before the month is over, he will learn a lesson and not spend money so freely. He will learn what his limitations (限制) are and feel the difficulty when he has to pay for something that is over his own pocket.
Rajiv Patel: Yes, I would give my child pocket money because it is important that he learns to manage money. But I would not give it to him on a weekly or monthly basis. He would have to earn it. If he helped me finish some of my jobs or helped his mother with housework, I would reward him. This helps him realize that “money does not grow on trees” and it requires hard work to earn money.
小題1:Ashish Khanna may agree that _____.
A．he was given too much pocket money when young
B．he can take much control of his child by money
C．he will buy anything he thinks his child really needs
D．pocket money helps children develop a good value for money
小題2:The underlined phrase “on the sly” in Paragraph 3 is the closest in meaning to “_____”.
A．for freeB．a(chǎn)t a lower price
C．happilyD．secretly
小題3:Who would give his child pocket money every month?
A．Ashish Khanna.B．Sharad Sanghi.
C．Rakesh Shah. D．Rajiv Patel.
小題4:What do Rakesh Shah and Rajiv Patel have in common?
A．They want their children to learn to manage money from an early age.
B．They ask their children to get pocket money by working.
C．They teach their children the difficulty of making money.
D．They allow their children to spend money freely.

When a Swedish ship that sank（沉） in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century.  In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.
Underwater archaeology(考古)-the study of ships, aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years.  The rapid growth of this new area of study has occurred because of the invention of better diving equipment. Besides the Swedish ship wreck(殘�。瑄nderwater archaeologists have made more exciting discoveries such as the  5000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts abut the past. In ancient ports all over the world are ships sunken in the past 6, 000 years.  There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world's knowledge of history, but they have to fight two enemies.  One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors.  Once sold, these objects are lost to experts.  The second enemy is dredging machines(挖掘機）often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.
小題1:What purpose does Paragraph 1 serve in the passage?
A．To provide background information of the topic
B．To attract readers' attention to the topic
C．To use an example to support the topic
D．To offer basic knowledge of the topic
小題2:The aim of underwater archaeology is to    .
A．exploit(開發(fā))water bodies B．search for underwater life
C．study underwater artifacts D．examine underwater environment
小題3:Underwater archaeologists are worried because_____.
A．sea hunters have better diving equipment　
B．their knowledge of world history is limited　
C．dredging machines cause damage to the ports　
D．sold artifacts can hardly be regained for research
小題4:What is the main purpose of the passage?
A．To introduce a young branch(分支) of learning.
B．To discuss the scientists’ problems. 　
C．To explain people’s way of life in the past. 　
D．To describe the sunken ships.

A volcanic eruption in Iceland has sent ash across northern Europe Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.
Grimsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier(冰川) of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer(層)of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava(巖漿) from the volcano then comes up to the surface. This is exactly what happened today.
