As the circus packed up and left, circus officials said the show would go on, even without tigers. However, the officials cann't simply turn a blind eye to the ethical problems left behind. Even before this tragedy , animal rights activists protested against keeping wild animals in unnatural conditions and forcing them to suffer for the profit of circus organizers. It is now time for us to take effective steps to make sure that circus animals are treated properly. ******************************* Circus Safe for Animals Our circus recently suffered a most tragic event in its history. While we are thankful for the pity from the public, we are also astonished by the opinion expressed in "Tragedy at the Circus. " First, our performing animals are not taken from the wild. As to the ethical problems. we always believe humans and animals can--and should--live together nicely. To us, the performing animals are representatives of their species , and our circus is one of the only places left willing to support this special role of performing animals in the existence of the species. Those who argue that circus life is harmful to animals show little knowledge of these facts. Life in the "wild" is unsafe, but a continuous struggle for existence. To overlook these realities is the greatest fault against the animal kingdom. This circus has proven that animals are stronger and smarter than we could imagine. Within the circus is a joyful atmosphere for both animals and humans: people are educated, and species saved. Question: What does the circus think of its performing animals? - They are as clever as human beings. - They struggle continuously with human beings for existence. - They are helpful in saving their species. - They have equally natural living conditions as wild animals.
They are helpful in saving their species.

Article: "Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity," researchers recently reported in the journal Hypertension. "Sugar-sweetened soft drinks are a significant source of calorie intake in children," said Feng J. He, a researcher at St George's University of London, England. "It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people." They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption. Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. "We found that children eating a lower-salt diet drank less fluid," said He. "From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day." The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. "If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week," Dr He said. In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. "Both high blood pressure and obesity increase the risk of having strokes and heart attacks," Dr He said. Dr He recommends that parents check labels and choose low-salt food products. "Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors and do not cause any technological or safety problems," Dr He said. Question: Which of the following statements would Dr He agree to? - The less salt people eat, the healthier people become. - Children should reduce fluid intake in their daily life. - No high-salt food products will be available in shops. - A low-salt diet may prevent both high blood pressure and obesity.
A low-salt diet may prevent both high blood pressure and obesity.

(Question)
Read the following article and select the best answer. Article: The food we eat seems to have profound effects on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet. Therefore, that food is connected with illness is not a new discovery. In 1940's scientists realized that nitrates , which are often used to keep color1 of meat, and other additives caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example, farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this. Question: According to the passage, what has science done to mankind? - Because of science there is no polluted food any more. - Science makes food have less value. - As a result of scientific invention, some things that may be harmful have been added to our food. - Now the scientists can keep the color1 of meat but not that of vegetable.
(Answer)
As a result of scientific invention, some things that may be harmful have been added to our food.
