fluenzalike cases. Influenza is sometimes called "flu" or a "bad cold". He took samples from the throats of patients and in his hospital was able to find the virus of this influenza.

There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he didn't know the sub-group. He reported the outbreak to the World Health Organization in Geneva. WHO published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%～20% of the population had become ill.

As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs used against all the known sub-groups of type A virus. None of them gave any protection. This then, was something new; a new influenza virus against which the people of the world had no ready help whatsoever.

Having isolated the virus they were working with, the doctors now conducted tests on some specially selected animals, which contracted influenza in the same way as human beings did. In a short time the usual sign of the disease disappeared. Theses experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply "Asian" flu.

The influenza discovered by a doctor in Singapore is caused by ______.

A．a new type of virus

B．type A virus

C．a sub-group of type B virus

D．a virus only existing in Asia

of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual the sort of environment in which he is reared (抚养). If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster (收养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

any different ways throughout the history.

For example, it is recorded in many history books that people who lived over 3000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve the dead.

In some periods of history, a person who stole salt was thought to have broken the law. Take the eighteenth century for example, if a person was caught stealing salt, he would be thrown into prison. History also records that only in England about ten thousand people were put into prison during that century for stealing salt! About 450 years ago, in the year 1553, if a man took more than his share of salt, he would be thought to have broken the law and would be seriously punished. The offender's ear was cut off.

Salt was an important item on the dinner table of a king. It was always put in front of the king when he sat down to eat. Important guests at the king's table were seated near the salt. Less important guests were given seats farther away from it.

Thousands of years ago in Egypt salt was used ______.

A．to punish people who had broken the law

lowers were his main joy in life. He grew flowers of every color under the sun. He grew these flowers in order to enter them for competition. His greatest hope in life was to grow a rose of an entirely new color that would win him the silver cup for the Rose of the Year.

Mr. Flowers' glasshouse was close to a public path, which was always used by children walking to and from school. Boys were often attracted to throw a stone or two at his glasshouse. So Mr. Flowers did his best to be in or close by his glasshouse at the beginning and end of the school day.

However, it was not convenient or possible to be on guard all the time. Mr. Flowers had tried in many ways to prevent harm to his glass; but nothing that he had done had been successful.

Then, just as he was giving up hope of ever winning the battle, and of growing the Rose of the Year, he had a truly wonderful idea. He put up a large notice made of good, strong wood, some metres away from the glasshouse, where it could be' clearly seen from the path. He had painted on the board the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble. The boys were much more attracted to throw stones at the notice than at the glasshouse.

Mr. Flowers' great hope is ______.

A．to grow beautiful flowers

B．to grow the Rose of the Year and win a prize

C．to grow all kinds of flowers in the world

D．to take part in the competition

To a philosopher, wisdom is not the same as knowledge. Facts may be known in enormous numbers without the knower of them loving wisdom. Indeed, the person who possesses encyclopedic (学识渊博的) information may actually have a genuine contempt (轻视) for those who love and seek wisdom. The philosopher is not content with a mere knowledge of facts. He desires to combine and evaluate facts, and to examine beneath the obvious to the deeper orderliness behind the immediately given facts. Insight into the hidden depths of reality, perspective (洞察) on human life and nature in their entirety, in the words of Plato, to be a spectator of time and existence--these are the philosopher's objectives. Too great an interest in the small details of science, may, and often does, obscure these basic objectives.

Philosophers assume that the love of wisdom is a natural gift of the human being. Potentially every man is a philosopher because in the depths of his being there is an intense longing to penetrate to the meaning of the mysteries of existence. The inner deep longing expresses itself in various ways prior to any actual study of philosophy as a technical branch of human culture. Consequently every human being in so far as he has ever been or is a lover of wisdom has, to that extent, a philosophy of life.

The title below that best expresses the idea of this passage is ______.

A．The Potential Philosopher

B．The Philosophy of Plato

C．The Philosopher Versus the Scientist

lass in driver's education.

The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.

After a student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver's test. The person must pass all three tests in order to be given a driver's license. If the person does well in his or her driver's education class, he or she will pass the test with flying colors and get a driver's license.

In America, the driver's course mentioned above______.

A．is considered as part of the advanced education

B．is given to anyone wanting to get a driver's license

C．is carried on after students graduate from high school

D．is offered to all the students of Grade 2 in high school
