The following are all bad reading habits EXCEPT __________.

For many people today, reading is no longer relaxation. To keep up their work they must read letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In getting a job or advancing in one, the ability to read and comprehend quickly can mean the difference between success and failure. Yet the unfortunate fact is that most of us are poor readers. Most of us develop poor reading habits at an early age, and never get over them. The main problem lies in language itself—words. Single words have little meaning until they are combined into phrases, sentences and paragraphs. Unfortunately, however, the untrained reader does not read groups of words. He reads one word at a time, often regressing to reread words or passages. Regression, or looking back over what you have just read, is a common bad habit in reading. Another habit which slows down the speed of reading is vocalization—sounding each word either orally or mentally as one reads.To overcome these bad habits, some reading clinics use a device called accelerator (加速器), which moves a bar down the page at a predetermined speed. The bar is set at a slightly faster rate than the reader finds comfortable, in order to “stretch” him. The accelerator forces the reader to read fast, making word-by-word reading, regression and vocalization virtually impossible. At first, comprehension is sacrificed for speed. But when you learn to read ideas, you will not only read faster, but your comprehension will improve. Many people have found their reading skills improved a lot after some training.

A、regression

B、reading for ideas only

C、vocalization

D、word-by-word reading

Something big is happening to the human race—something that could be called The Great Tran

sformation.

The Transformation consists of all the changes that are occurring m human life due to advancing technology. For thousands of years such progress occurred slowly. Now, everything is changing so fast that you may find yourself wondering where all this progress is really leading.

Nobody knows what all these changes really will mean in the long run. But this mysterious Transformation is the biggest story of all time. It is the story of the human race itself.

Some people worry about what will happen when the deposits of petroleum are gone, but already researchers are finding all kinds of new ways to obtain energy. Someday, solar power collected by satellites circling the earth of fission power manufactured by mankind may give us all the energy we need for an expanding civilization. Space exploration promises to open up many new territories for human settlement, as well as leading to the harvest of mineral resources like the asteroids.

Scientific research continues to open up previously undreamed-of possibilities. Fifty years ago, few people could even imagine things like computers, lasers, and holography. Today, a host of newly emerging technologies such as artificial intelligence and genetic engineering are opening up all kinds of new paths for technologists.

Like it or not, our advancing technology has made us masters of the earth. We not only dominate all the other animals, but we are reshaping the world's plant life and even its soil and rocks, its waters and surrounding air. Mountains are being dug up to provide minerals and stone for buildings. The very ground under our feet is washing away as we chop down the forests, plow up the fields, and excavate foundations for our buildings.

Human junk is cluttering up not only the land but even the bottom of the sea. And so many chemicals are being released into the air by human activities that scientists worry that the entire globe may warm, causing the polar icecaps to melt and ocean waters to flood vast areas of the land.

During the twentieth century, advancing technology has enabled man to reach thousands of feet into the ocean depths and to climb the highest mountains. Mount Everest, the highest mountain of all, resisted all climbers until the 1950's. Now man is reaching beyond Earth to the moon, Mars, and the stars.

No one knows what the Great Transformation means or where it will ultimately lead. But one thing is sure: Human life 50 years from now will be very different from what it is today.

It's also worth noting that our wondrous technology is posing an increasingly insistent question: When we can do so many things, how can we possibly decide what we really should do？ When humans were relatively powerless, they didn't have to make the choices they have to make today.

Technology gives us the power to build a magnificent new civilization—if we can just agree on what we want it to be. But today, there is little global agreement on goals and how we should achieve them.

So it remains to be seen what will happen as a result of our technology. Pessimists worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown—but we can continue to hope.

The Great Transformation is caused by______.

A．artificial intelligence and genetic engineering

B．the shortage of natural resources

C．the development of practical science

D．unknown reasons

第5题

‘I. Q.' stands for Intelligence Quotient which is a measure of a person's intelligence fou

nd by means of an intelligence test. Before marks gained in such a test can be useful as information about a person, they must be compared with some standard, or norm. It is not enough simply to know that a boy of thirteen has scored, say, ninety marks in a particular test. To know whether he is clever, average or dull, his marks must be Compared with the average achieved by boys of thirteen in that test.

In 1906 the psychologist, Alfred Binet(1857—1911), devised the standard in relation to which intelligence has since been assessed. Binet was asked to find a method of selecting all children in the schools of Paris who should be taken out of ordinary classes and put in special classes for defectives. The problem brought home to him the need for a atandard of intelligence, and he hit upon the very simple concept of "mental age".

First of all, he invented a variety of tests and put large numbers of children of different ages through them. He then found at what age each test was passed by the average child. For instance, he found that the average child of seven could count backwards from 20 to 1 and the average child of three could repeat the sentence: "We are going to have a good time in the country." Binet arranged the various tests in order of difficulty, and used them as a scale against which he could measure every individual. If, for example, a boy aged twelve could only do tests that were passed by the average boy of nine, Binet held that he was three years below ave rage, and that he had a mental age of nine.

The concept of mental age provided Binet, and through him, other psychologists, with the required standard. It enabled him to state scores in intelligence tests in terms of a norm. At first, it was usual to express the result of a test by the difference between the "mental" and the "chronological" age. Then the boy in the example given would be "three years retarded". Soon, however, the "mental ratio" was introduced; that is to say, the ratio of the mental age to the chronological age. Thus a boy of twelve with a mental age of nine has a mental ratio of 0.75.

The mental age was replaced by the "intelligence quotient" or "I. Q. '. The "I. Q." is the mental ratio multiplied by 100. For example, a boy of twelve with a mental age of nine has an "I. Q." of 75. Clearly, since the mental age of the average child is equal to the chronological age, the average 'I. Q.' is 100.

In order to judge a child' s intelligence, his marks in a test must be compared with marks gained by

A．thirteen-year-old children

B．children of different ages

C．the same child at different ages

D．other children of the same age

第6题

Opinion polls are now beginning to show an unwilling general agreement that, whoever is to

blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely.

But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm？ Should we not create conditions in which many of us can work for ourselves, rather than for an employer？ Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work？

The industrial age has been the only period of human history in which most people's work has taken the form. of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought about may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom.

Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people's homes. Later, as transport improved, first by rail and then by road, people travelled longer distances to their places of employment until eventually, many people's work lost all connection with their home lives and places in which they lived.

Meanwhile, employment put women at a disadvantage. It became customary for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife.

All this may now have to change. The time has certainly come to switch some effort and resources away from the impractical goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.

What idea did the author derive from the recent opinion polls？

A．New jobs must be created in order to rectify high unemployment figures.

B．Available employment should be restricted to a small percentage of the population.

C．The present high unemployment figures are a fact of life.

D．Jobs available must be distributed among more people.

When a German couple noticed a man's head and shoulder sticking out of a glacier i

n the Austrian Alps recently, they made history.The frozen corpse was about five feet 11 and scientists who helicoptered to the site determined that it was 4,000 years old-the first 12 body ever found from the Bronze Age.Mummified by the wind and snow, he came 13 with skin, bones, internal organs, and fingernails.He was 14 in leather shoes and finely stitched leather suit, insulated with hay.An array of weapons and equipment was found alongside him 15 a leather quiver with fourteen arrows, a stone necklace, a fire flint, a knife, and a ax with a crude bronze head.

“The find is of 16 scientific meaning,” said Konrad Spindler, professor of Early and Primeval History at the University of Innsbruck, who is investigating the 17 .Skeletal remains of buried corpses have been excavated before in Bronze Age graves.But “the iceman,” as Austrian newspapers dubbed him, was going about the normal course of life when he died 18 the ages of 20 and 40, which means he should yield a treasure-trove of information about conditions 4,000 years ago.Scientists plan to 19 the contents of his stomach and intestine for clues to the Bronze Age diet, illnesses, and parasites.They also hoped to 20 the glacier site further for companions.

第10题

Why don't birds get lost on their long flights from one place to another？ Scientists have

puzzled over this question for many years. Now they're beginning to fill in the blanks.

Not long age, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long - distance flights.

A dove (鸽子) had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star - filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.

(77) But the stars are apparently their principal means of navigation (航行) only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.

The reason why birds don't get lost on long flights ______.

A．have been known to scientists for many years

B．have only recently been discovered

C．are known by us

D．will probably remain a mystery
