Be Brave With New Things

The old advertising slogan, “so simple a child can do it ,” has taken on new meaning to me. A few weeks ago I got a computer, but I an mechanically illiterate. I knew that children had no fear of the future, so that seemed a good place to seek help. I asked my nephew, twelve years old, at an elementary school, to help me.

My nephew took the machine for granted and has simply accepted the fact that computers are now a way of life. He plays with them and does his homework on them and even creates programs for them. I , on the other hand, are terrified by what this equipment can do. It can interchange paragraphs, switch words around and even correct my spelling. It informs me of Its limitations, takes commands and asks questions. It even seems to have a sense of communication. Rather than accusing me of making an error, it prints “One of us has made a mistake!” It never gets tired and is always patient and ready to go when I am.

I think it was somewhat normal for me to be suspicious of computers. They represent a break with some very familiar habits and traditions. It is only human to instinctively avoid anything that shifts thoroughly from the acceptable, comfortable past. But the world is governed by ceaseless change and we must therefore establish links with the present and future as well as the past. Computer technology is an excellent case in point, as the newest systems grow out of date in only a few years, or even months.

This ability to see, experience and accept the new is one of our saving characteristics. To be fearful of tomorrow, to close ourselves to possibilities, to resist the inevitable, to advocate standing still when all else is moving forward, is to lose touch. If we accept the new with joy and wonder, we can move gracefully into each tomorrow. More often than not, the children shall lead us.

7．According to the second paragraph, which of the following statements is true?

C．computers are not only used to communicate, but also to remove their limitations.

D．It is a fact that both adults and children have accepted computers as a way of life.

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of comet(彗星).When the fragments(碎片)landed in the southern part of the giant planet, the explosions were watched by scientist here on earth. But what if our own planet was hit by a comet?

The year is 2094. It has been announced that a comet is heading towards the earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the earth. The news has caused panic.

On 17 July, a fragment four kilometers wide enters the earth’s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The waves moves into the Indian Ocean and heads towards Asia.

Millions of people are already dead in the southern part of the earth, but the north won’t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.

Could it really happen? In fact, it has already happened more than once in the history of the earth. The dinosaurs(恐龙)were on the earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believed that the earth was hit by a space fragment. The dinosaurs couldn’t survive in the cold climate that followed and they became extinct. Will we meet the same end?

Salt plays an important role in our daily diet. Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict -how just three grams less a day would affect heart disease in the United States.

The result: Thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings. Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．

The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams,or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University. Each gram of salt contains four hundred milligrams of sodiu(钠), which is how foods may list their salt content．

The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.

New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative.The idea is to put pressure on food companies and restaurants. Critics call it government interference.

Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows that the calorie information on the menu can influence what parents order for their children. Ninety-nine parents of three to six year olds took part. Half had calories between the two groups for foods that the parents would have chosen for themselves. McDonald's menus clearly showing how many calories were in each food. Parents given the counts chose an average of one hundred two fewer calories when asked what they would order for their children. Yet there was no difference in calories between the two groups for foods that the parents would have chosen for themselves.

Study leader Pooja Tandon says even small calorie reductions on a regular basis can prevent weight gain over time.The study was published in the journal Pediatrics．

1.Which of the following benefits does less salt diet in the passage NOT cover?

A．The decrease of strokes B．The prevention of weight gain

C．Fewer heart attacks D．The drop in medical care cost

2.It can be inferred from the passage that _______.

3.The National Salt Reduction Initiative aims to_______.
