The modern age is an age of electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to imagine what life would be like without them. When there is a power failure, people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights to guide them, and food spoils in silent refrigerators.
Yet, people began to understand how electricity works only a little more than two centuries ago. Nature has apparently been experimenting in this field for million of years. Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.
All living cells send out tiny pulses of electricity. As the heart beats, it sends out pulses of record; they form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends our brain waves of electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small,often so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all. When large numbers of these cells are linked together, the effects can be astonishing.
The electric eel is an amazing storage battery. It can send a jolt of as much as eight hundred volts of electricity through the water in which it lives. ( An electric house current is only one hundred and twenty volts, but two hundred and twenty volts in China.) As many as four-fifths of all the cells in the electric eel's body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body
56. Electricity was invented ______.
A. when man had no candles
B. about 200 years ago

D. by Thomse Edison

B. Electrical generators and animal muscle.
C. Stones and dry wood.
D. human brain and living cells.
58. The electric current send out by an eel can be
A. as much as 800 volts. B. about one hundred and twenty volts.
C. as high as the house current in China. D. stored in the water where it lives.
59. From this shot passage we can infer _____.
A. the shorter an eel is, the stronger electricity it produces.
B. we can always feel the electricity produced by living cells.
C. human beings get their knowledge about electricity from nature.
D. people learn about electricity from eels.

The “Sepik Spirit”, constructed in 1989, is built specially to suit the demands of a shallow riverboat for guiding inland waterways. Its shallow draft allows passengers into distant corners of the Sepik Region and areas not otherwise accessible to larger boats. It was refurbished(装修) in early 2006 to ensure that the Sepik Spirit meets the expectations of the modern travellers. The refurbishment includes new interior and improved noise resistance.
The Sepik Spirit holds 18 passengers in 9 twin bedrooms each with private bathroom. Onboard facilities include a dining room, living room, bar, video and covered upper observatory deck(甲板). The entire boat is air-conditioned. Because the Sepik Spirit is designed to operate in this unique environment, she is the ideal size for exploration. This, combined with small passenger numbers, allows the travellers an excellent experience to little visited areas.
Day trips from the Sepik Spirit are done in an 18-seater riverboat, also designed for the operation. Their open-air design gives the travellers a sense of place, a feeling for the river and its people.
Areas that the Sepik Spirit and her guests may visit are the Karawari River, Blackwater Lakes, Chambri Lakes, the Middle Sepik and the Upper Sepik. The river banks where the boat operates are dotted with many large traditional villages each with its own unique “Haus Tambaran” or spirit house decorated with ancestral figures.

In many homes, divorce is caused by the “battle between the sexes.” To understand the problem, one must remember that the modern American woman is freed. During childhood and adolescence(青少年期), the American girl is given freedom and education which is equal to a boy's. After completing school, she is able to get a job and support herself. She doesn't have to marry for financial security. She considers herself an independent, self-sufficient person. She wants a husband whom she can respect, but she doesn't want to be dominated(控制) by him. She wants a democratic household in which she has a voice in making decisions. When a husband and wife are able to share decisionmaking, their marriage is probably closer, stronger, and more satisfying. Otherwise, the couple is likely to wind up in the divorce court.
When a couple gets divorced, the court usually requires the man to pay his former wife a monthly sum of money. If the couple has children, they usually remain with the mother, and the father is expected to pay for their support.
Although divorce is quite common in the United States, 80 percent of those who get divorced remarry. The remarriages allow thousands of people, especially children, to enjoy family life again, but at the same time many troubles have arisen. A well-known American joke tells of a wife calling to her second husband, “Quick, John! Come here and help me! Your children are beating up our chidlren!”

Prague is an ancient European city, featuring one of the most magnificent Old Towns in Europe, along with delicious food, inexpensive shopping and friendly people. Prague is also famous as being home to one of the most famous 20th century writers, Franz Kafka. The famous Czech beer is also one of the reasons to visit Prague.

B
People tend to become more personal and hide less of themselves when using email. Researchers from Open University in Britain have found in a recent study that there are good reasons for this.
The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: If only five people in the world could be saved from a world disaster, who should they be? The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with cameras so that students could see each other, this limited the personal side of the conversation.”
Generally the information was not extremely personal. It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.
Dr Johnson believes that emailing encourages people to focus on themselves. And when they do this, they become more open, especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself. This is because you are not thinking what the other person is thinking of you. So emailing has become the modern way of talking,” said Dr. Johnson. However, this style of talking is not entirely new. “In the 19th century people started to use the ‘telegraph’ to communicate. Now the same kind of thing has happened and people ended up speaking more freely.”
Dr. Johnson thinks that emailers need to know about these effects of emailing, especially when they start work in a company. “ If you don’t know about it, you could find yourself saying more about yourself than you wanted to.”
60. The subject discussed in this passage is _______.
A. how people open up when emailing B. how people do research studies
C. how to communicate at work D. how to discuss and solve a problem
61. The reason that some couples talked freely about themselves is that _______.
A. they didn’t talk about very personal things B. they couldn’t see each other
C. the cameras on the computers were turned on D. they had to discuss a question
62. What does the underlined sentence refer to?
A. The telegraph. B. The computer. C. Emailing. D. Face-to-face talk.
63. In the writer’s opinion, one should ______.
A. focus on oneself when emailing B. talk more freely in emails than usual
C. discuss any subject that one wants to D. consider how one uses email at work
