D
Are some people born clever, and others born stupid? Or is intelligence developed by our environment and experience? Strangely enough, the answer to these questions is yes. To some extent, person’s intelligence is fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随意地) from the population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We should soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
68. The writer is in favor of the view that man’s intelligence is given to him
A. at birth B. through education
C. both at birth and through education D. neither at birth nor through education
69. If a child is born with low intelligence, he is unlikely to
A. become a genius so long as he or she works hard enough
B. still become a genius if he should be given special education
C. go beyond his intelligence limits even in rich surroundings
D. never reaches his intelligence limits in his life
70. The example of the twins going to a university and to a factory separately shows
A. the importance of their intelligence
B. the role of environment on intelligence
C. the importance of their positions
D. the part that birth plays
71. What can be the best title for the text?
A. Surroundings B. Intelligence
C. Dependence on Environment D. Effect of Education

A mosquito is an insect that is found all over the world．There are thousands of different kinds of mosquitoes in many different sizes and colors．The female mosquito needs blood from vertebrates （脊椎动物）to lay eggs and produce more mosquitoes．She has a special part of her mouth that she uses to suck blood，and her saliva（spit）thins the blood so she can drink it．In fact．It’s the mosquito’s saliva that makes the bites itch（痒）!
A person who gets bitten by a mosquito will notice a wheal，which is a bump around the bite．
The wheal will be round，with pink or red around the edge and white in the middle．The wheal will
itch a lot．Soon the wheal will disappear, but the itch will stay．
If you’ve been bitten by a mosquito，wash the bite with soap and water．Put on some calamine lotion to help stop the itching，or an adult can find an anti-itch cream at the drugstore for you．Placing an ice pack on the bite may also help．Tell an adult you’ve been bitten by a mosquito，especially if you live in the eastern United States．But if you develop an allergic reaction and feel dizzy or sick，tell a doctor immediately．He can treat allergic reactions with sole medicine．
The best way to avoid mosquito bites is to wear an insect repellent．Repellents that include one of these ingredients are best：BEET and lemon eucalyptus．Ask a parent to help you apply them．
Since mosquitoes lay their eggs in water，it’s also a good idea to empty out buckets，flower pots，toys and other things in your yard that may have collected water during a rainstorm．And when it’s possible，you’d better wear long-sleeved shirts and long pants to keep mosquitoes away from your skin．
60．What makes you itch after the mosquitoes’bites?

D．Ask a parent for an insect repellent if you see mosquitoes laying their eggs in water．
Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body"s temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits (or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system(循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.
The main benefits(or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says. "When I go into the water, I pour my troubles into the ocean and let them float away."51. The members of the Polar Bear Club must meet the following requirements except that_____ .

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
