If you are interested in animals, you probably heard about the tragedy at Seaworld Orlando. On February 24, Tillicum, a six-ton orca(虎鲸)，was performing with his trainer, Dawn Brancheau, who stood on a platform by his pool.
They had done the same show together many times before, without incident. This time, though, events took a terrible turn. Without warning, Tillicum leaped from the water, took hold of Branchcheau by her hair, and dragged her deep below the water’s surface. Before other trainers could react, Brancheau drowned.
Although known as killer whales, orcas are the largest member of the dolphin family. They are easy to train, and performances like Tillicum’s have been done safely thousands of times. Yet Dawn Brancheau’s death was a shocking reminder of what can happen when human being act together with wild animals. People began to ask, “Should orcas be kept in captivity(囚禁)”
Yes
Worldwide, only 42 orcas are being kept by humans. Scientists know very little about these huge sea animals, which are difficult to study in the wild. However, they do know that orcas are easily harmed by pollution. As our oceans become ever more damaged by human activity, observing orcas up close helps us understand them and do a better job of protecting them in nature.
“I think that some dangerous animals, such as killer whales, should be kept in captivity because it raises awareness about them and educates people about wild animals,” says Lauren, 12, a 6-grader from Colorado. “Keeping some in captivity will help protect their species.”
No
Enclosed habitats can be painful to wild animals, and make them act in unpredictable even harmful ways.
“It is wrong to keep these animals in captivity”, says Prathm, 12 The 7th grader from New Jersey, adds, “They should live in their own habitats, not be used as entertainment slaves.”
Richard Ellis, a marine conservationist in New York, agrees. “It is part of human nature to keep wild animals in small spaces and train them to do tricks,” he says. “I’m against it because I think it humiliates the animals.”Why does the author tell the tragedy of Dawn Brancheau ?

Edgar felt quite excited at the thought of his first swim of the summer. With the sun shining down so strongly, the sea was certain to be warm enough. He walked quickly along the sea-front towards the steps that led on to the sands. He smiled cheerfully at the passersby. He had just smiled and raised his hat to an elderly lady when a man with a camera caught his arm and stopped him. Edgar heard a little buzzing noise from the camera.
“Your photograph, sir, in glorious colour in just one moment if you please,” said the man in one breath. Then the buzzing stopped, and he held the photograph in his hand and was waving it to and fro. In a
moment he handed it over, and Edgar saw the bright blue splash of his shirt half filling the picture.
“Seventy pence, sir,” the man said. “It’s the bargain of your holiday.”
“Seventy pence,” Edgar repeated, mildly. “For this?” He stared at the photographer.
“They’re normally eighty-five, sir, but for a single subject I make a cut-price offer. It’s the best value you’ll get in Chadwell.”
“You’ll have to make a better offer,” Edgar said. It was a good photo though, he thought, so bright and clear. His hat was held high, and he was smiling broadly at the old lady, whose arm and handbag came into a lower corner. He had had no idea that he was being snapped. He thought he was really quite a good-looking chap.
“That’s as good as any studio job that would cost you pounds,” said the cameraman. “It’s better in a way because it’s so natural. Only seventy pence, sir.”
“I’ve never paid so much for a snap in my life. It simply isn’t worth that kind of money. It’s not as if I need the thing. Look, I’ll give you twenty-five.”
“No, I can’t do that. Each of these instant colour shots costs me 50p — that’s the price of the blank frame, so you see…”
“Criminal, criminal,” Edgar broke in. “You want a profit of forty per cent. Well, not at my expense, I’m afraid. I’ll give you your 50p and that’s that.”
“Let me see, then.” The man suddenly took the photograph out of Edgar’s hand. “I can’t waste any more time with you. It’s 70p or I keep it.”

LONDON (Reuters) — Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine.
More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters.
The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions.
In the case of HIV/AIDS, the few existing pediatric therapies（儿科的疗法）developed for children generally cost three times more than adult ones.
As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose.
Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children.
“But a lot remains to be done. There are priority medicines that have not been adapted for children’s use or are not available when needed,” said Dr Hans, the U.N. agency’s director of medicines policy and standards.
Medicines that need to be adapted to children’s needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria.
The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year.
Testing medicines on children has always been a controversial issue, since good ethical（伦理的）practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children.
As a result, research-based drug companies have been wary of developing child-friendly medicines and general companies have been slow to produce them at lower cost.
In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children.Which of the following is the best title of the passage?
| A．A Global Campaign to Promote Research into AIDS Medicine |
| B．WHO Says Children are Dying for Lack of Child-sized Drugs |
| C．Many People are Concerned about Children’s Drugs |
| D．Measures Taken to Develop Child-friendly Medicine Quickly |
Which of the following medicine is not needed to be adapted to children’s need according to the passage?
| A．Pain killers. | B．Tuberculosis. | C．AID pills. | D．Flu pills. |
Why has testing medicines on children always been a controversial issue?
| A．It is against good ethical practice |
| B．Children shouldn’t take part in clinical trials. |
| C．It is hard to get informed agreement from children tested. |
| D．Parents don’t allow their children to be tested on medicine. |
The underlined word “wary” in the last but one paragraph means _________.
| A．fast | B．fond | C．cautious | D．uninterested |
What can be inferred from the passage?
| A．There is still a long way to go on children’s medicine. |
| B．An Internet entrance is being built to link to clinical trials carried out in children. |
| C．Both Europe and the United States now have special rules offering extended patent protection for adults’ drugs. |
| D．Less than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters |
Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢)becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
It can be inferred from Para. 2 that __________.
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |

Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various species in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.
Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.
All domestic animals need proper food. It must be suitable for them, sufficient inquantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps(剩饭), and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.
Even well-cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.What main idea does the author want to convey in the first paragraph?
| A．There exists thousands of species of animals in the world. |
| B．Man came to establish a close relationship with a number of animals. |

Looking back on my childhood. I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental maths.
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together .This has resulted in my publishing 300 papers and books. Which some may light honor, with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist? One of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.According to the author, a born naturalist should first of all be _____
