Animals Can Sense Natural Disasters
Among the dead in South Asia’ s tsunami（海啸）were many tourists at Sri Lanka’ s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and run away to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound（次声）. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration（震动）. The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints（关节）, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears.Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?
| A．Because human beings cannot hear the infrasonic sound. |
| B．Because the animals were staying at a higher place in the park. |
| C．Because the animals were able to run much faster than human beings. |
| D．Because the animals might have picked up the danger signals and ran away. |
Which of the statements about “Rayleigh waves” is true?
| A．Rayleigh waves can be felt both by animals and human beings. |
| B．Rayleigh waves, just like infrasonic sound, can only be felt by animals. |
| C．Rayleigh waves are vibrational waves that usually cause quakes or tsunamis. |
| D．Rayleigh waves move on the ocean surface at a speed ten times that of sound waves. |
According to the passage, which of the statement is true?
| A．We can’t feel the infrasound so we can’t be informed of the danger. |
| B．We ignore the information of tsunami’s coming even though we can also get it. |
| C．We were so busy on our minds that we feel neither infrasound nor Rayleigh waves. |
| D．We can feel Rayleigh waves and infrasound so we can escape the danger like animals. |
A 69-year-old grandmother with no teeth of her own has eventually won a long legal battle to stop a Scottish regional council（政务委员会）adding fluoride（氟化物）chemical to the public water supply.
In a case which has already cost the taxpayer ￡1,000,000, the judge ruled that it was beyond the powers of the local authority to add the chemical to the water in order to reduce tooth decay.
At her home last night Mrs Catherine fluoride to public drinking water made it into some kind of dirty soup. “Where would it stop?” she asked. “They might come up with the idea of putting drugs into the water to keep the unemployed quiet.” It was a horrible poison, she said, that could have caused al kinds of diseases, including cancer.
The judge, however, concluded that there was no evidence to suggest that the inclusion of fluoride in the water supply would have had a negative effect on pulpier health. Although the chemical might serve as an efficient and convenient means of achieving a beneficial effect on the dental health of consumers generally, he said, and its use was greatly favored by the dental profession, he could also understand why some members of the public, Mrs McColl in particular, might be passionately opposed to the action of the Water Authority in assuming the right to improve public well-being without consulting t77he public in the first case. The Authority’s legal duty to provide “wholesome” water for public consumption which was both safe and pleasant to drink ,did not, he said, extend to their right to safeguard public health by chemical means.
72．Mrs McColll felt so strongly about the fluoride issue that she eventually .
A．took the local council to court
B．had a physical fight with the judge

73．According to what the judge said in the passage, adding fluoride to the water .
A．wasn’t proved to be harmful
B．was the duty of the local authority
C．was strongly poised by dentists

A．the improvement of their personal health
B．the problem of unemployment in their community
C．the chemicals to be used for the improvement of water quality
D．their right to be informed of the authorities’ decisions

All over the world, children in hospital are being treated with a new kind of medicine: laughter. Lucy is 23 and works for Theodora Children's Trust. She is one of many clown（小丑）doctors who bring a smile to the faces of sick children.
"I'm a Theodora clown doctor. I call myself Dr Looloo. I spend two days a week in children's hospitals, making funny faces, telling jokes, and doing magic tricks. As I walk into the wards I blow bubbles, shake hands with the kids, and make up nonsense songs for those children well enough to sing. I take special balloons to make 'balloon animals' and tell funny stories about them.
I'm naturally a very cheerful person. I've always been a clown. In fact my father's a clown a d I started working with him when I was eight year old. I knew it was just the job for me and I became a clown doctor because I think it's a great way to cheer up sick, frightened children in hospital.
Being a clown in hospital is very tiring both physically and emotionally. We have to learn not to show our feelings, otherwise we'd be useless. Clown doctors are sensitive but this is not a side most people see. To the children we're happy all the time. I'm still learning to allow myself to feel sad occasionally. There are special kids you get really close to. At the moment I'm working with a very sick little girl from Bosnia who speaks no English, so our only common language is laughter.
At weekends I participate in events to raise money for Theodora Children's Trust. It's a charity, so we are paid with the money people give. Being a clown doctor makes the worries of everyday life seem small. All in all, feel honoured to do this job. "

We spent a day in the country, picking wild flowers. With the car full of flowers we were going home. On our way back my wife noticed a cupboard outside a furniture shop. It was tall and narrow. “Buy it, ” my wife said at once. “We’ll carry it home on the roof rack. I’ve always wanted one like that.”
What could I do? Ten minutes later I was ￡20 poorer; and the cupboard was tied on the roof rack. It was six feet long and eighteen inches square, quite heavy too.
In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea.
After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake, I wonder?” In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me.
“Right, sir, ” he said. “Do you need any more help?”
I was a bit puzzled. “Thanks, officer, ” I said. “You have been very kind. I live just on the road.”
He was staring at our car, first at the flowers, then at the cupboard. “Well, well, ” he said, laughing. “It’s a cupboard you’ve got there! We thought it was something else.”
My wife began to laugh. The truth hit me like a stone between the eyes. I smiled at the officer. “Yes, it’s a cupboard, but thanks again.” I drove home as fast as I could.

三、阅读理解：
It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problems and that they have no sense of humor, at least in parent-child relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are superior, at least in a small way, and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they did approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog: you can’t win but at least you can keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself.
If you plan to control your life, co-operation can be part of that plan. You can charm others, especially parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.
