C
Can you imagine a catfish bigger than a boy? There are more than 1，000 kinds of catfish；28 species are found in the United States" lakes and rivers． This huge family has some mighty strange members. Let"s meet a few.
Walking catfish．Nature"s feisty little catfish，found in southern Florida，has an extra lung for breathing on dry land. When its swimming hole dries up，the walking catfish waddles on stiff forward fins in search of another lake or stream．If an enemy attacks，the fish flares（展开）its top and front fins and leaps at the attacker to scare it off．
Armored catfish．This catfish has heavy，bony plates protecting its body. The shell makes the fish difficult to bone. To cook it，throw the fish whole into a fire. When it is done，break it open for eating．Some armored catfish are found in Florida，but the 100-pounders live in South America．
Rounding out the family of strange catfish are talking catfish，which make growing sound when you pull them from the water；climbing catfish，which move quickly up shore brush in search of food；electric catfish，which can deliver a mild shock；and blind catfish，which settle in the inky blackness of underwater caves．Blind catfish find food through taste buds in their eight whiskers（须）．
Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water．The United States does not have catfish anywhere near the size of those in South America．But in some large U.S，rivers，blue and flathead catties do top 100 pounds．
Most of the catfish you are likely to catch will be much smaller，about frying pan size．When you catch one，remember that the top fins and the forward fins have poison glands（腺）at their bases. They can give you painful wounds （…）

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man"s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea．
The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.
Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused． This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.
45．The underlined phrase “disposed of ”in the second paragraph means_______.
A． dealt with              B． exposed
C． disapproved of          D． collected
46． In the writer’s view ,the more new goods, _______.
A． the less pollution
B． the harder pollution can be prevented
C． the more pollution there will be
D． the more easily pollution can be controlled
47．What can we learn from the last paragraph?
A． We can do much to reduce pollution.
B． The government is trying hard to stop pollution.
C． Individuals know how to get rid of the habit of littering everywhere.
D． We can’t stop buying unnecessary things.
48． People can help solve the problem of pollution by _______.
A． urging their governments to control litter and waste
B． making anti-pollution advertisements
C． cutting down the use of oil and other oil products
D． reducing unnecessary buying, over-consumption and careless disposal of wastes

What is a good education? The question is far from being answered. Once more, colleges and universities are changing their programs: they drop "fun courses" and restart some of the traditional subjects neglected (忽视) since the 1960s. Many great schools are again requiring the students to take a number of classes in English, history, literature, the social sciences, philosophy, the natural sciences, and art if they want to get a degree. Meanwhile, the experts are trying to describe the good education of our time. Obviously the purely vocational training once favored is not enough. But neither is the gentleman"s education of the nineteenth century. Educational programs must meet the demands of a modern world where men and women have to work and to deal with big problems.
What, then, is a good education of this century? Some educators suggest that it should include foreign languages and the study of foreign cultures; a mastery of English, including the ability to write and speak well, because communications have become all-important in the modern world, and also because "a person who doesn"t speak and write clearly doesn"t reason clearly either"; some knowledge of the social sciences (sociology, psychology) that deal with human relations and human problems; some basic knowledge of modern science, which would enable future voters to be better informed about current problems like nuclear. Finally, many educators insist that all college graduates should be familiar with computers and modern information system since the educated professionals of tomorrow will have to understand their machines. Is that all? "No, of course not." answer the educators. "We have not mentioned the two great building blocks of education: history and literature!"
71．The best title for this passage might be _______.
A．Education           B．A Mastery of English
C．A Good Education   D．Something About Study
72．The underlined word "drop" in the first paragraph means _______.
A．desert       B．dislike      C．decline     D．neglect
73．The author thinks that the question about what a good education is _______.
A．has been answered fairly well
B．hasn"t been put forward yet
C．has been dealt with successfully
D．has not been answered satisfactorily
74．Some educational experts believe a mastery of English should include the ability _______.
A．to read fast                        B．to write and speak well
C．to write clearly and accurately    D．to listen and speak skillfully
75．Which of the following statements is not mentioned in the passage?
A．Educational programs must meet the demand of a modern world.
B．The students will not get a degree unless they take a number of classes in English, history,
literature, the social sciences, philosophy, the natural sciences and art.
C．A good education should include foreign language and the study of foreign culture.
D．Every student ought to take part in military training.

Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could．Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas．And right here on Earth, we"ve learned how to warm a planet: just add greenhouse gases to its atmosphere．Much of the CO₂ that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water．
Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself． "You don"t build Mars," Mackay says．"You just warm it up and throw some seeds．" Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO₂, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow．Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession （系列） of ecosystems ?first bacteria and lichens （地衣）, which survive in Antarctica, later mosses （苔藓）, and after one thousand years or so, redwoods．Getting breathable oxygen levels out of those forests, though, could take thousands of years．
However, Mars is in no immediate danger．Some space scientists recently recommended going to the moon or an asteroid （小行星） first, and pointed out the space agency lacks the funds to go anywhere．It didn"t estimate the cost of gardening a dead planet．
72．What is the most essential to make Mars fit for living?
A．Turn ice into flowing water．          B．Clean the dirty atmosphere．
C．Make the atmosphere more suitable．    D．Go to the moon or an asteroid first．
73．What does the author think of the idea ofterraforming Mars?
A．We could do it．                            B．We couldn"t do it．
C．We should do it．                           D．We shouldn"t do it．
74．In the botanist"s opinion, man needs to __________.
A．enable Mars to clean its atmosphere
B．build a greenhouse on Mars
C．send some people to settle on Mars
D．cultivate ecosystems from lower to higher life form
75．What is the best title for the passage?
A．Making Mars the New Earth．           B．A Good Way to Change the Universe
C．Humans" Great Power．                     D．Terrible Science and Technology．

The other day in school, we were discussing jobs. Our teacher, Mrs. Bolt said that career was very important and that it was never too early to think about your life’s work. Most of the young boys really were not too sure about what they wanted to be. But I knew exactly what I wanted to be, and when Mrs. Bolt asked me, I replied “A truck driver.”
“A truck driver?” repeated Mrs. Blot. “Why do you want to be one, Tom?”
“Because truck drivers are always on the move. They do not have to sit at desks all day. They are out on the road and they see a lot of the country. The pay is good, too. And you never have any homework.”
The class laughed.
“Well, Tom.” answered Mrs. Bolt. “You certainly sound quite enthusiastic (热情的). I guess that you don’t like sitting at a desk or doing homework. Is that correct, Tom?”
“Yes, I guess so, ” I said.
“Well, since you are so interested in becoming a truck driver, I think you should look into the field a little further. I want you to go to the library and take out a book on truck driving. And I want you to write a paper on it and hand it in at the end of the month.”

On a good night when there is no Moon and the air is clear, only up to 4,000 or so stars can be seen by the unaided eye. From ancient times star – watchers have tried to bring some order into the sky by fitting the stars into patterns. The constellations (星座) to which names were given.
Observation of the night sky every few hours shows that in the northern hemisphere(半球) the stars appear to turn anticlockwise (逆时针方向) about a point near the Pole Star. As they turn, the stars keep the same positions in relation to each other, and in fact the appearance of the constellations has changed very little over the centuries. Like the Sun and Moon, the stars have a daily journey across the sky, rising upwards in the east and setting in the west – due to the Earth’s daily spin. The Circumpolar Stars, those near the Pole Star, are an exception to this; they are so close to the pole that they never disappear below the horizon (地平线) Although the stars always rise in the same places they do not do so at the same time every day. They rise about 4 minutes earlier each day since the Earth is progressing in its orbit around the Sun; in almost but not exactly a year they again rise and set at the same time. If a certain star is seen to rise in the east exactly when the Sun sets on a particular day, a few weeks later it will be seen well above the eastern horizon at sunset.
58．Which do you think is the best title of the passage above?
A．The Earth, the Moon and the Stars. B．Motion of the Stars.
C．How to Watch the Stars. D．Appearance of the Stars.

59．Which of the following descriptions cannot be shown in the picture?
A．The Circumpolar stars never disappear below the horizon.
B．The relative position of the stars in a constellation remains more or less the same as they move.
C．Stars appear to turn about a point near the Pole Star.
D．Stars appear to turn anticlockwise in the northern hemisphere.
60．From the passage we can learn that __________.
A．scientists can observe only up to 4,000 stars on a clear night
B．every day the stars always rise in the same place at the same time
C．thousands of years later, people may have to rename the constellations as the positions of the stars in them have changed
D．since the earth spins from the west to the east every day, most stars rise in the east and set in the west
61．Where is the passage probably taken from?
A．A fashion magazine B．A newspaper advertisement.
C．A science textbook. D．A collection of science fiction stories.
