The age of space science began less than thirty years ago. But already people have mad

e great discoveries and have done exciting things. They have walked in space, visited the moon, and lived in space laboratories for long periods of time. Some scientists are now working on ways to make it possible for people to live on other planets. They are trying to solve problems of living in space, even though they don’t yet know what all of the problems will be. For example, they don’t’ yet know what problems people would have if they loved being weightless for several years.

If you were a space traveler you might have to spend several months, or even years, in a spaceship. While you were in the ship you wouldn’t live as you usually do. You might have to find new ways to spend your time. Your body would have to adjust to different conditions. And you would have some problems that you never think about here on earth. For example, you would have to have a huge supply of food with you because you can’t go to the supermarket when you’re halfway to another planet. You also would need fresh water and a way to get rid of waste. In fact, there would be many problems to solve in order to live in space.

A. people who were light had many problems

B. many problems people would face in space

C. many people who loved to be very light

D. weightless people who loved to have problems

3. The phrase “a huge supple of food” (Para.2) means ________.

A. a huge piece of food

B. the food that is largely supplied on the market

C. a large amount of food

D. the food at the supermarket

4. While you were in the spaceship, you would NOT _______.

A. need fresh water and a way to get rid of waste

B. have some unusual problems

C. go to the supermarket when you were halfway to another planet

D. find new ways to spend your time

5. It can be concluded from the passage that _________.

The space age officially began on October 4, 1957,【B1】the Soviet Union launched the modest
185-pound Sputnik I, the first【B2】satellite to orbit the earth. The following month, Russians successfully launched the 1100 pound Sputnik II,【B3】carried into space the globe, a female dog【B4】Laika, who suffocated(窒息) on the sixth day of the【B5】because of a failure【B6】the internal temperature of the craft. But the satellite itself orbited the earth for 162 days and【B7】on re-entering the earth's atmosphere. The United States,【B8】second fiddle(小提琴) to its superpower【B9】, orbited its first satellite, Explorer 1, on January 31, 1958. It was a lightweight, 18-pound craft, carrying not animals but【B10】instruments to study the【B11】hands of energy in space【B12】the Van Allen radiation belts.

第4题

With a tremendous roar from its rocket engine, the satellite is sent up into the sky. Minu
tes later, at an altitude of 300 miles, this tiny electronic moon begins to orbit about the earth. Its radio begins to transmit a staggering amount of information about the satellite's orbital path, the amount of radiation it detects, and the presence of meteorites. Information of all kinds races back to the earth. No human being could possibly copy down all these facts, much less remember and organize them. But an electronic computer can.

The marvel of the machine age, the electronic computer has been in use only since 1946. It can do simple computations—add, subtract, multiply, and divide—with lightning speed and perfect accuracy. It can multiply two 10-digit numbers in 1/1, 000 second, a problem that would take an average person five minutes to do with pencil and paper. Some computers can work 500, 000 times faster than any person can.

Once it is given a program, that is, a carefully worked-out set of instructions devised by a technician trained in computer language, a computer can gather a wide range of information for many purposes. For the scientist it can get information from outer space or from the depths of the ocean. In business and industry the computer prepares factory inventories, keeps track of sales trends and production needs, mails dividend checks, and makes out company payrolls. It can keep bank accounts up to date and make out electric bills. If you are planning a trip by plane, the computer will find out what route to take and what space is available.

Why does the author regard the electronic computer as the marvel of the machine age？

A．Because electronic computers are rare.

B．Because people know little about electronic computers.

C．Because electronic computers can do much more kinds of work that human beings can't.

D．Because electronic computers have been widely suspected.

In a study of the effect of color on productivity, 50 of 100 factory workers were moved fr
om their drab workroom to a brightly colored workroom. Both these workers and the 50 who remained in the drab workroom increased their productivity, probably as a result of the interest taken by researchers in the work of both groups during the study. Which of the following, if true, would cast most doubt upon the authors interpretation of the study results given above？

A．The 50 workers moved to the brightly colored room performed precisely the same manufacturing task as the workers who remained in the drab workroom.

B．The drab workroom was designed to provide adequate space for at most 65 workers.

C．The 50 workers who moved to the brightly colored workroom were matched as closely as possible in age and level of training to the 50 workers who remained in the drab workroom.

D．Nearly all the workers in both groups had volunteered to move to the brightly colored workroom.

E．Many of the workers who moved to the brightly colored workroom reported that they liked the drab workroom as well as or better than they liked the brightly colored workroom.

Star birth, which transformed primordial gas into the countless starry galaxies of the pre
sent day universe, surged to high levels much earlier than astronomers had thought. Two teams of observers have looked into the early universe for the longwavelength radiation that signal star formation in dusty young galaxies. In tomorrow’s Nature, they report seeing galaxies rapidly spawning stars when the universe was less than a third of its present age.

Astronomers have been searching at great distance -- which correspond to earlier times -- to find the heyday of star birth. But interstellar dust is thick in star-forming regions hiding the light of hot young stars and reradiating it in the infra red. Observations by infrared satellites have already revealed large number of star-forming galaxies as much as halfway back to the big bang. But for even older, more distant stars and galaxies, the expansion of the universe stretches the infrared radiation into the submillimeter waveband, a twilight region of the spectrum between infrared and radio.

Earlier this year, a U. K. team led by Michael Rowan -- Robinson of London’s Imperial College pointed a submillimeter telescope on Mauna Kea, Hawaii, at the Hubble Deep Field, the small patch of sky where the Hubble Space Tele scope captured optical images of some of the most distant galaxies ever. Five of the brightest submillimeter sources they found match up with faint, old galaxies in the Hubble image, and four of the five date from when the universe was between a third and a fifth of its present age -- up to 9 billion years ago. Their submillimeter brilliance indicates that these galaxies are spawning stars perhaps 100 times faster than our own galaxy, says team member James Dunlop of the University of Ed inburgh. A U. S. -Japanese group has made other submillimeter images that support this picture of frenzied star birth in the early universe.

The observations are "a very exciting new development," says Max Pettini, an astrophysicist at Britain’s Royal Green wich Observatory. Star formation, he says, is "part and parcel of the broader question of how the universe evolved from the smooth conditions of the big hang into the galaxies we see today. "However, Charles Steidel of the California Institute of Technology cautions that the distance and hence the age of these submillimeter sources is "somewhat ambiguous, "because of the submillimeter camera’s coarse resolution.

From the third paragraph we know that ______.

A．an American team pointed a submillimeter telescope in Hawaii

B．the team used Hubble space Telescope and captured optical images of some galaxies

C．they found five faint old galaxies

D．there are several galaxies in the universe

根据下面内容，回答题：

Scientists in the UK have announced that the piranhafish"s reputation 21 a fearsome 22 may well not be deserved. The fish， which is found in the Amazon in Brazil， have been 23 as deadly carnivores（食肉动物 ） that work in shoals to overwhelm their prey and strip it of its flesh in seconds.

However， experts 24 St Andrews University say that piranhas are omnivores（杂食动物） that mainly eat fish， plants and insects. They form. big groups not to hunt but to defend 25 against other predators， according to the team.

"Previously it was thought piranhas shoaled as it 26 them to form. a cooperative hunting group，" said Professor Anne Magurran. " 27， we have found that it is primarily a defensive behavior. "

Piranhas can be attacked by animals 28 dolphins， caimans and large fish， so forming a shoal is a good way of 29 being killed. Piranhas of 30 age stay in the middle of the group for 31 and the 32 of the shoal differs according to the level of 33 When the water level is 34， the fish form. small groups as there is space to escape， but when the water level drops， they form. large groups as protection 35 predators.

第10题

The human brain contains 10 thousand million cells and each of these may have a thousand c
onnections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human - like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long 6me to render it intelligent by loading in the right software(软件)or by altering the architecture but that too will happen.

I think it certain that in decades, not centuries, machines of silicon(硅)will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

As the intelligence of robots increased to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on each through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further a head, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man - created world in space, home to thousands or millions of people, will be within our power.

In what way can we make a machine intelligent？

A．By making it work in such environments as deserts, oceans or space.

B．By working hard for 10 or 20 years.

C．By either properly programming it or changing its structure.

D．By reproducing it.
