The eagle, America’s national Symbol, had been shot and poisoned and deprived of its living space. Another reason for its decline lay in it nesting habits. Bald eagles do not bread until they are 3 to 5 years old, and then they normally produce only two ergs per year. The eagle often returns each year to the same nest so preservation of nesting areas is important.

Congress took action to protect the eagle in 1972. Criminal penalties for killing a bald eagle may be as much as a $ 20000 fine and one year in prison or one year in prison. Healthy eagle eggs have also been transplanted from unpolluted areas to another ones where eggshells are very thin, and young birds with a high survival rate have been brought in from Canada.

One reason for the bald eagle’s low number is

A. Its early breeding period.

B. The small number of eggs it produces every year

C. That it only nests in preservation areas

D. The fact that it returns to similar nesting areas every year

Animals have an intuitive awareness of quantities. They know without analysis the difference between a number of objects and a smaller number. In his book "The Natural History of Selboure" (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a plover's nest, and how the mother laid another egg each day to make up for the missing one. He noted that other species of birds ignore the absence of a single egg but abandon their nest if more than one egg has been removed. It has also been noted by naturalists that a certain type of wasp always provides five - never four, never six - caterpillars for each of their eggs so that their young have something to eat when the eggs hatch. Research has also shown that both mice and pigeons can be taught to distinguish between odd and even numbers of food pieces.

These and similar accounts have led some people to infer that creatures other than humans can actually count. They also point to dogs that have been taught to respond to numerical questions with the correct number of banks, or to horses that seem to solve arithmetic problems by stomping their hooves the proper number of times.

Animals respond to quantities only when they are connected to survival as a species - as in the case of the eggs - or survival as individuals - as in the case of food. There is no transfer to other situations of from concrete reality to the abstract notion of numbers. Animals can "count" only when the objects are present and only when the numbers involved are small - not more than seven or eight. In lab experiments, animals trained to "count" one kind of object were unable to count any other type. The object, not the numbers, are what interest them. Animals' admittedly remarkable achievements simply do not amount to evidence of counting, nor do they reveal more than innate instincts, refined by the genes of successive generations, or the results of clever, careful conditioning by trainers.

The word "surreptitiously" is closest in meaning to ________.

A. stubbornly

B. secretly

C. quickly

D. occasionally

The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and anaesthetics. Patients do riot often believe they really need surgery- cutting into a part of the body as opposed to treatment with drugs.

In the early year of the 20^th century, there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Cloyed blood vessels can be clean out, and broken ones mended and replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.

The scope of surgery has increase remarkable in the past decades. Its safety has increased, too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example, to certain types of birth defects in new born babies, and at the other end of the scale, to life-saving operation for the octogenarian .The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.

One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few decades ago, no person, except an identical twins, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.

“Spare parts” surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if the doctors say to you: “Yes, l think it is possible to operate on you for this condition”.

Surgeons in the early 20^th century compared with modern ones ______.

A. had less to learn about surgery.

B. needed more knowledge.

C. were more trusted by their patients.

D. could perform every operation known today.

Read-the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

THE SAVANNAH

The tourist looking at the African savannah on a summer afternoon might be excused for thinking that the wide yellow grass plain was completely deserted of life, almost a desert. With only a few small thorn trees sticking out through the veldt, there seems to be almost no place for a living creature to hide.

However, under those trees you might find small steenbok, sleeping in the shade, and waiting for the night to fall. There may even be a small group of lions somewhere, their bodies exactly the same shade as the tall grass around them. In the holes in the ground a host of tiny creatures, from rabbits and badgers to rats and' snakes are waiting for the heat to finish.

The tall grass also hides the fact that there may be a small stream running across the middle of the plain. One clue that there may be water here is the sight of a majestic Marshall eagle circling slowly over the grassland. When he drops, he may come up with a small fish, or maybe a grass snake that has been waiting at the edge of a pool in the hope of catching a frog.

The best time to see the animals then, is in the evening, just as the sun is setting. The best time of the year to come is in late September, or early August, just before the rains. Then the animals must come to the waterholes, as there is no other place for them to drink. And they like to come while it is still light; so they can see if any dangers are creeping up on them.

So it is at sunset, and after the night falls, that the creatures of the African veld rise and go about their business.

The phrase "be excused for" in paragraph 1 is closest in meaning to

A. easily make a mistake of

B. feel sorry for

C. be regretting for

D. be actually forgiven for

A. Of all animals, dogs and horses can count best

B. Careful training is required to teach animals to perform tricks involving numbers

C. Although animals may be aware of quantities, they cannot actually count

D. Animals cannot "count" more than one kind of object
