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

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.

A small piece of fish each, day may keep the heart doctor away. That’s the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce(英两) of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long-held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption average more than 3 ounces.
F or 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol levels.What is the author’s attitude towards the topic?
| A．Disappointed. | B．Sad. | C．Concerned. | D．Satisfied. |
We can infer from the passage that there are fewer heart disease deaths in the countries .
| A．that are highly developed | B．with a lot of fish |
| C．with high consumption of fish | D．where it is very cold |
The underlined words “This relationship” refers to the connection between and deaths from heart disease.
| A．the amount of fish | B．regular fish – eating |
| C．the kind of fish eaten | D．people of different areas |
The passage is mainly about .
| A．the changes in people’s diet |
| B．the effect of fish – eating on people’s health |
| C．the high percentage of heart disease in some countries |
| D．the daily fish consumption of people in different cultures |
Do you want to have a mobile phone? Have you had a mobile phone already? Nowadays more and more students have their own mobile phones, and mobile phone use has become a problem for middle schools. Some middle schools in China have banned students from carrying mobile phones during school hours.
Mobile phone use among children has become a big problem for the school this year. Some children have got mobile phones as birthday gifts, and more students want them.
Wang Pi, an official, said, “Mobile phone use is a distraction (分散注意力的东西) to students during school hours and it also gives teachers so much trouble in their classrooms.” Teachers were also saying that sometimes students might use phone messages to cheat during exams.
Wang Pialso said some schools had tried to ban mobile phones, but some parents felt unhappy because they couldn’t get in touch with their children.
Many teachers said students should not have mobile phones at school, but if their was a good reason, they could leave their phones at school offices. They also said there were many reasons why the students should not have mobile phones at school. They were easy to lose and were a distraction from studies.
Many people say that they understand why parents would want their children to have phones, but they think schools should let the students know when they can use their mobile phones.Some middle schools have banned students from carrying mobile phones .

For several days I saw little of Mr. Rochester. In the morning he seemed very busy with business, and in the afternoon gentlemen from the neighborhood called and sometimes stayed to dine with him. When his foot was well enough, he rode out a great deal.
During this time, all my knowledge of him was limited to occasional meetings about the house, when he would sometimes pass me coldly, and sometimes bow and smile. His changes of manner did not offend me, because I had nothing to do with the cause of them.
One evening, several days later, I was invited to talk to Mr. Rochester after dinner. He was sitting in his armchair, and looked not quite so severe, and much less gloomy. There was a smile on his lips, and his eyes were bright, probably with wine. As I was looking at him, he suddenly turned, and asked me, “Do you think I am handsome, Miss Eyre?”
The answer somehow slipped from my tongue before I realized it: “No，sir.” “Ah，you really are unusual! You are a quiet, serious little person, but you can be almost rude.” “Sir, I'm sorry. I should have said that beauty doesn't matter, or something like that.” “No, you shouldn't! I see, you criticize my appearance, and then you stab (刺) me in the back! You have honesty and feeling. There are not many girls like you. But perhaps I go too fast. Perhaps you have awful faults to counterbalance your few good points.”
I thought to myself that he might have too. He seemed to read my mind, and said quickly, “Yes, you're right. I have plenty of faults. I went the wrong way when I was twenty-one, and have never found the right path again. I might have been very different. I might have been as good as you, and perhaps wiser. I am not a bad man, take my word for it, but I have done wrong. It wasn't my character, but circumstances which were to blame. Why do I tell you all this? Because you're the sort of person people tell their problems and secrets to, because you're sympathetic and give them hope.”
It seemed he had quite a lot to talk to me. He didn't seem to like to finish the talk quickly, as was the case for the first time.
“Don't be afraid of me, Miss. Eyre,” he continued. “You don't relax or laugh very much, perhaps because of the effect Lowood school has had on you. But in time you will be more natural with me, and laugh, and speak freely. You're like a bird in a cage. When you get out of the cage, you'll fly very high. Good night.”

The effects of rapid travel on the body are actually far more disturbing than we realize. Jet Lag is not a psychological consequence of having to readjust to a different time zone. It is due to changes in the body’s physiological regulatory mechanisms, specifically the hormonal systems, in a different environment.
Now that we understand what Jet Lag is, we can go some way to overcome it. A great number of the body’s events are scheduled to occur at a certain time of day. Naturally these have to be regulated, and there are two regulatory systems which interact.
One timing system comes from the evidence of our senses and stomachs, and the periodicity we experience when living in a particular time zone. The other belongs in our internal clocks (the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus) which, left alone, would tie the body to a 25-hour rhythm. Normally the two timers are in step, and the surroundings tend to regularize the internal clocks to the more convenient 24-hour period.
If, however, you move the whole body to a time zone which is four hours different, the two clocks will be out of step, like two alarm clocks which are normally set together, but which have been reset a few hours apart. Whereas the two clocks would normally sound their alarms together, now they ring at different times. Similarly, the body can be set for evening while the sun is rising.
In time the physiological system will reset itself, but it does take time. One easily monitored rhythm is palm sweating. A man flown to a time zone different by 10 hours will take eight days to readjust his palm sweat. Blood pressure, which is also rhythmical, takes four days to readjust.
What can we do about it? It is not feasible to wait four days until the body is used to the new time zone. Fortunately there is a short cut. It relies on two things-the power of the stomach to regulate the timing of other events, and the pharmacological actions of coffee. The basic assumptions are:
Coffee 
delays the body clock in the morning, and advances it at night. Coffee at mid-afternoon is neutral. Protein in meals stimulates wakefulness, while carbohydrates promote sleep. Putting food into an empty stomach helps synchronize the body clock.
46. What is jet lag associated with?
A. Psychological change.B. Physiological change.
C. Inexperience of rapid travel.D. Unfamiliar environment.
47. What helps us to adjust to a 24-hour rhythm?
A. Alarm clock.B. Suprachiasmatic nucleus in our brain.
C. Signals from outside of the body. D. Our senses and stomachs.
48. What do we know from the fifth paragraph?
A. A person moving to a different time zone will suffer from high blood pressure.
B. A person moving to a different time zone will sweat a lot.
C. Moving to a different time zone will affect both palm sweat and blood pressure.
D. If the rhythm of blood pressure and palm sweat are not in step, there will be jet lag.
49. What should we do if we want to stay awake?
A. To take coffee at three o’clock in the afternoon.
B. To have meals that contain lots of protein.
C. To have some carbohydrate drinks.
D. To stop putting food into our stomach.
50. How can we cure jet lag?
A. To sleep for days. B. To wait for self-recovery.
C. To drink tea.D. To get something to eat.

Anyone who is addicted to reading bus tickets or cereal packets will understand the appeal of poems on the underground. Some years ago, a few acquaintances who lived and worked in London , who used the Tube and loved poetry, decided that it would be pleasant to read a few lines by their favorite poets as they traveled around by Tube, instead of just glancing upwards at the tiresome advertisements. The underground had a surplus (剩余的)of advertising space on the trains. They suggested filling the blank space on the trains, for the entertainment of the traveling public.
The poems took on a new life when they were removed from books and placed alongside the adverts. Commuters enjoyed the idea of reading Keats’“Much have I traveled in the realms of gold” on a crowded Central Line train, or trying to learn by heart a sonnet between Hammersmith and Piccadilly. The choice of poems wasn’t arbitrary （随机的）but specially chosen. It catered for all tastes including living and dead poems from the homeland and from all over the English-speaking world, and especially poems which have association with London.
The success of the poems on the underground enterprises confirmed that Britain was a nation of poetry lovers. Hundreds of people corresponded with London Underground suggesting poems, or just to say thank you. In January 1989, on the third anniversary after the first poems on the Underground, London Underground promised to donate all the spaces free, to increase the number available (at least one poem in each train carriage), and to pay for the production costs as well. They also updated the poems every few months. Posters of the poems decorated the British Council libraries throughout the world, but th
e best way to view the poems is to see them by yourselves, on whichever train you choose, in every zone of the network—for the price of an underground ticket.
41.Which of the following is the best title for the passage?
A. Shelly and Keat’s Poems
