题目内容
The way we get about has a deep influence on the way we live－affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演员) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.

A quarrel at home may result in you falling ill. Don’t laugh, it’s true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.
Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.
“We don’t get sick or stay well by ourselves,” says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research. The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA.
Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too. Ferrer’s research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick.
We may never fully understand all the effects that families have on our health. But just as individual (个别的) problems can have effects on others, a small improvement can have big benefits, Ferrer said.
【小题1】Which of the following can best explain why Wang Xiaoyu fainted in class?
| A．Because her classmates often quarreled in class. |
| B．Because her parents used to quarrel. |
| C．Because of her depression caused by bad family relations. |
| D．Because her classmates shouted loudly at her. |
| A．We get sick or stay well by ourselves. |
| B．Only the genes we get from our family have a big effect on our health. |
| C．Our health has nothing to do with diet, lifestyle and environment. |
| D．Teenagers who are ignored at home get sick more easily than those who are not. |
| A．surprise | B．faint | C．tiredness | D．sadness |
| A．Family relations. | B．The reasons why we get sick. |
| C．Family---- another cause to health | D．A research about health. |
I came to live here where I am now between Wounded Knee Greek and Grass Greek。Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power.
This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves.
Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the “white people” have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to grow up.
