Dolphins are not fish; they’re mammals. They are warm-blooded like man and give birth to one baby called a calf at a time. At birth a calf is about 90—130cm long and grows to about 4m. They live up to 40 years. They are highly sociable animals.

Their teeth are interlocking rows of hooks, suitable for holding slippery fish. They eat fish whole starting with head first. When they go wild they keep their mouth open and sometimes keep it nodding to express their aggression. Greater aggression is shown by violent jaw clapping. Dolphins breathe through their blowhole(呼吸孔) located at the top of their head. The dolphin’s eyes produce a special slippery secretion(分泌物) which protects the eyes from foreign objects and water friction.

Dolphins use their powerful tail to move through the water. They also use their tail while hunting. They slap their tail rapidly when they get annoyed or when they want to indicate the sign of danger to alert other dolphins.

The dolphin’s skin is completely smooth allowing the dolphin to move easily through the water, and also reduce heat loss. Their skin may bear rake marks from other dolphin’s teeth during play or mating, and can easily become badly sunburned if they strand(搁浅).

Their bodies are very streamlined so they may swim at high speed through the water, and an example of this is their ears. Dolphin’s ears are barely noticeable marked only by a small hole just behind the eyes.

While sleeping, it shuts down only half of its brain, as its breathing is under voluntary control. Dolphins take short catnaps, floating just below the surface, and then slowly rising to breathe. Often dolphins are very active during night time, for some this is their main feeding time. Dolphins are able to dive to great depths, and also leap to great heights. They may leap to avoid predators or to show how powerful they are to females at mating time.

The church seems cold this morning, even after all the people, friends and family, fill the benches. I sit here in silence, in shock and denial. This was not supposed to happen. What about our dreams, or our plans? We were going to raise our children, travel the world, and grow old together. I’m only 37, a typical housewife. I don’t know if I can do all this alone—two children, no father. What do I do or say?

The faces of so many people confuse me as they come to pay their last respects. Some have real sorrow; I can see it in their eyes. The others seem to just say, “I told you so.” Those famous last words: I-told-you-so. How I can’t stand them. And the pointing fingers as so-called family and so-called friends pick me out of the crowd for others to see. I want to scream and wake up but I can’t do anything but sit there. How can they be so blind? I fell in love with a man. Love knows no boundaries .

He was a good man, hardworking, caring and kind. He was retired from the Navy and a gentleman. He was sensitive to others’ needs, the kind of man that knew what to do or say, how to humor any situation and calm everyone’s fears. I remember our first child was a big surprise to both of us. I remember when I told him the news. He fell off his chair, saying over and over in disbelief, “But I’m almost sixty.” After a few months he started planning our next and even doing his famous little dance whenever he discussed the idea.

A man, thirty years older than I, lies in a coffin. Flowers, the American flag and his VFW comrades surround him, paying tribute（颂词）to him as the man he really was. And I sit alone here, with our two children, in silence, praying that this cold morning at church is only a nightmare and I will awake to his loving arms again.

How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces, They are taller, to reach higher branches. They have shorter tusks（象牙）, and most importantly, longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families. They drink only every 3 –4 days, and can store water in a  “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders – they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage.

During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine（尿液）to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.

The underlined part in Paragraph 2 means “            ”.

A．remains in the African countries

B．drinks 120 liters of water a day

C．manages to live in desert areas

D．eats 150 kilograms of food daily

Desert elephants are called careful feeders because they _________.

A．rarely ruin trees

B．drink only every 3-4 days

C．search for food in large groups

D．protect food sources for their young

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
