When a magazine for high school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate(旋转)so they could follow the sun to take maximum advantage of its light and heat. Walls would “give light” and “change color with the push of a button.” Food would be replaced by pills. School would be taught by electrical impulse(电脉冲)while we sleep. Cars would have radar(雷达). Does this sound like the year 2000? Actually, this article was written in 1958 and the question was, “what will life be like in 1978?

The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accuately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on Cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in “airbuses”, large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents “almost unheard of”. Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was “The city of 1982”.

If the professionals sometimes sound like high school students, it’s probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accuate, and generally it is. But there have been some big mistakes in the field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers.

One forecaster knew that predictions about the future would always be subject to significant error. In 1957, H.J. Rand of the Rad corporation was asked about the year 2000, “Only one thing is certain,” he answered. “Children born today will have reached the age of 43.”

1.How many examples does the author offer to describe the future life?

A. Three B. Four C. Five D. Six

2.The high school students’ answers to “What would life be like in 1978?” sound __________.

A. accurate B. imaginative C. correct D. foolish

A. economy forecasting is rather a new field

B. experts began economy forecasting in 1929

C. the predictions about economic situation caused the investors to lose lots of money

5.H.J.Rand’s prediction about the year 2000 shows that ________.

A. it is easy to figure out in advance what will happen

B. it is difficult to figure out in advance what will happen

C. only professionals can figure out in advance what will happen

D. very few professionals figure out in advance what will happen

 

I lost my sight when I was four years old by falling off a box car in a freight yard in Atlantic City and landing on my head.Now I am thirty two.I can slightly remember the brightness of sunshine and what color red is.It would be wonderful to see again, but a calamity(灾难) can do strange things to people.It occurred to me the other day that I might not have come to love life as I do if I hadn't been blind.I believe in life now.I am not so sure that I would have believed in it so deeply, otherwise.I don't mean that I would prefer to go without my eyes.I simply mean that the loss of them made me appreciate the more what I had left.

The hardest lesson I had to learn was to believe in myself.That was basic.If I hadn't been able to do that, I would have collapsed and become a chair rocker on the front porch for the rest of my life.When I say belief in myself I am not talking about simply the kind of self confidence that helps me down an unfamiliar staircase alone.That is part of it.But I mean something bigger than that: an assurance that I am, despite imperfections, a real, positive person; that somewhere in the sweeping, intricate(错综复杂的) pattern of people there is a special place where I can make myself fit.

It took me years to discover and strengthen this assurance.It had to start with the simplest things.Once a man gave me an indoor baseball.I thought he was making fun of me and I was hurt."I can't use this." I said."Take it with you," he urged me, "and roll it around." The words stuck in my head."Roll it around! "By rolling the ball I could hear where it went.This gave me an idea how to achieve a goal I had thought impossible: playing baseball.At Philadelphia's Overbrook School for the Blind I invented a successful variation of baseball.We called it ground ball.

All my life I have set ahead of me a series of goals and then tried to reach them, one at a time.I had to learn my limitations.It was no good trying for something that I knew at the start was wildly out of reach because that only invited the bitterness of failure.I would fail sometimes anyway but on the average I made progress.

Our body clock,or natural body rhythm,influences our energy and alertness.Paying attention to it can help us choose the suitable time of day when we best perform specific tasks.

The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society.

But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor.

When the body clock can synchronize(使……同步)the rhythms of its natural processes,it “gives us an advantage in daily life”,says Key.

According to him,when it comes to cognitive(认知的)work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve.

However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted(分心)between noon and 4 pm.

Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap.

Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.

When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering.

Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans.

1.If we know our natural body rhythm well, we can .

A.find out the suitable time to do specific tasks

B.organize our time around work demands

3.According to Steve Key,which of the following is NOT true?

A.When our body clock synchronizes the rhythms of its natural processes,we can do better.

B.When it comes to cognitive(认知的)work,most people perform best in the late morning.

C.As body temperature rises before awakening in the morning,our concentration gradually improves.

D.We concentrate better in the late morning than between noon and 4 pm.

4.Inspiration(灵感)to solve a difficult problem will most probably come to us .

A.when we get up in the morning

B.when we are tired in the evening

If you are not any kind of a longtime A-list New Yorker celebrity like Woody Allen,chances are that you have never experienced,and will never experience-a meal in a legendary(神奇) Italian-American restaurant called Rao’s.

Rao’s,the East Harlem restaurant with a history of more than l00 years,is simply the toughest restaurant to get a reservation in the US, if not the world.Michelin three-star restaurants like elBulli in Spain,often ranked the world’s top restaurant,would sell out the second phone lines opened.But in the case of Rao’s,the phone lines never open.

There are about a dozen tables in the tiny restaurant, and each is spoken for, semi-permanently, as regulars have had their reservations for years, and when they can't use them,they often gift them to friends. The place is so small that the owners rarely have the flexibility to do favors even for people they know.

Since it is always busy,there has never been a need for publicity.The last remarkable national review of the restaurant came from The New York Times more than 35 years ago.It was already tough to get a table at Rao’s but reservations have been non-existent ever sincce the magic review.

According to a critic who is “very, very lucky to have dined at Rao’s a few times,”the experience rivals(堪比)the tasty food.There are no menus at Rao’s, and one of the owners will pull up a chair and run through the massive list of options, allowing people to have diner by mixing and matching nearly any ingredient(原料)with any classical Italian style of cooking. The place doesn’t take credit cards, isn’t open on weekends or for 1unch, and “at some point during your meal the one-room restaurant will almost unavoidably break out in song.” It is truly one of a kind,”the critic wrote.

When another old cave is discovered in the south of France,it is not usual news.Rather,it is art ordinary event.Such discoveries are so frequent these days that hardly anybody pays heed to them.However,when the Lascaux cave complex was discovered in 1940,the world was amazed.Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago.The scenes show people hunting animals,such as bison or wild cats.Other images show birds and,most noticeably,horses,which appear in more than 300 wall images,by far outnumbering all other animals.

Early artists drawing these animals accomplished a monumental and difficult task.They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex.

Unfortunately,the paintings have been exposed to the destructive action of water and temperature changes,which easily wear the images away.Because the Lascaux caves have many entrances,air movement has also damaged the images inside.

Although they are not out in the open air, where natural light would have destroyed them long ago,many of the images have been destroyed and are barely recognizable.To prevent further damage,the site was closed to tourists in 1963,23 years after it was discovered.
