Scientists find that hard-working people live longer than average men and women. Career wo

men are healthier than housewives. Evidence shows that the jobless are in poorer health than jobholders. An investigation shows that whenever the unemployment rate increases by 1%, the death rate increases by 2%. All this comes down to one point: work is helpful to health.

Why is work good for health？ It is because work keeps people busy away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest are those who are busy. (76) Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality. By work people come into with each other. By collective activity they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man spiritually and makes him ill.

Besides, work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.

(77) From the above we can come to the conclusion that the more you work the happier and healthier you will be. Let us work hard and study and live a happy and healthy life.

The underlined word "average" in Paragraph 1 means ______.

A．healthy

B．lazy

C．ordinary

D．poor

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

The majority of the grains—about 80%—were from cereal cropslike barley (大麦), andabout 10% were bits of roots, 32 lily,which would have sweetened the brew, the scientists say.

Futurists love computers. After all, 40 years ago electronic digital computers didn't exis

t; today microchips (微型集成电路片) as tiny as a baby's fingernail are making all sorts of tasks faster and easier. Surely the future hold still more miracles.

Some of the computer experiments now going inspire imagination of the future. For example, scientists are working in devices that can electronically perform. some sight and hearing functions, which could make easier for the blind and deaf. They are also working on artificial arms and legs that respond to the electric impulses (脉冲) produced by the human brain. Scientists hope that someday a person who has lost an arm could still have near-normal brain control over an artificial arm.

Video games, computerized effects in movies, and real-life training machines now being used by the U. S. Army are causing some people to predict new educational uses for computers. Computers could someday be used to imitate travel to other planets, to explore the ocean floor or to look inside an atom.

Experiment with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals (终端) . Cars, too, might be equipped with computers to help drivers find their way around or to communicate with home and office computers.

Many people, including handicapped (残废的) workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work—they'll just turn on a terminal.

Which of the following would be the most appropriate title for the passage？

A．Futurists and Computers

B．A Look at Future Uses of Computers

C．Computer Experiments

D．Scientists and Computers

Have you everheard Robot fish？ Scientistswill put some robot fishes into the seas nearSpai

n. These robot fishes will help people detect(探测) the pollution in the water. Ifthe robotfishes are able to finish their work successfully, the team of scientists hopes to putthefishesinto rivers,lakes and seas around the world.

The fishes are about 1.5 meters long and look like carps(鲤鱼). There will be a detector intheir bodies. They canfind the sources of pollutionin the water, and then the robot fisheswilleat part of it. Unlike other robots, they don’t need to be controlled by people faraway. Therobots all have an eight-hour battery. They can “swim” in the sea freely and send backinformation to people on the beach. After their batteries die, they will return by themselves.

There are five robot fishes altogether now.Each costs about 29,000 dollars. They are partof a three-year project between engineering company BMT Group and Essex University insoutheastern England.

“We designed the fishes creatively. We hopethe robot fishes can find the changes in the seawater and report back the information,” said Professor Huof Essex University. His team isdeveloping the fishes.

What will the robots do if they find the pollution in the water？

A.They will eat part of it.

B.They will stop working.

C.They will tell people where they are.

D.They will take it out to the beach.

How longcan a battery in their bodies work each time？A.For five hours

B.For eight hours.

C.For twelve hours.

D.For one day.

How much do the five robot fishes cost altogether？ A.$14, 500.

B.$29,000.

C.$145,000.

D.$1,450, 000.

Which of the following is TRUE？ The robot fishes ____.A.can eat anything in the water

第10题

In the opinion of many Americans and Europeans, we only began to really explore our world

in the sixteenth century. According to them, the sailors of the ancient world did not explore distant parts of the world; they did not have the necessary knowledge or skills for long sea journeys. However, the people who have this opinion are forgetting two important facts of history.

First, sometimes early scientists have an idea which is correct, but scientists in later centuries do not believe it. For example, about 270 B. C., a Greek scientist had an idea which we all believe today: The earth moves around the sun. But for the following 1,600 years scientists did not believe this. In their opinion, the sun clearly moved around the earth. They discovered the truth again only in the fifteenth century!

The second fact of history that many people forget is this: Ancient does not mean primitive. For example, the ancient Egyptians knew a great deal about the stars; they used this knowledge to find their way across the oceans. Two thousand years ago a Greek scientist who lived in Egypt calculated the distance around the earth. The results of his calculations were close to the real distance we know today! So the ancients had a great deal of scientific knowledge. They also had skills which equaled the skills of to- day. For example, 1,300 years ago and before, fishermen in Ireland built their boats of wood and leather. Today some fishermen in Ireland still make boats of the same de- sign. They use tools and materials which are not very different from the tools and materitals which their ancestors used. Why？ The ancient design of the boats was good, and with skillful sailors, these boats can sail in all kinds of weather.

Clearly long before the sixteenth century, people had the skill, the knowledge and the equipment which were necessary for long journeys by sea. The world did not have to wait until the sixteenth century for its first explorers!

Which of the following statements is consistent with the passage？

A．According to the writer, we only began to really explore the world in the sixteenth century.

B．In the history of science, people sometimes have to discover a fact a second time.

C．The ancient Egyptians had very little knowledge about the stars.

D．The writer agrees with many Americans and Europeans except for the two facts mentioned in the passage.
