Sports All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer. Sports change with the season. People play different games in winter and summer. Games and sports often grow out of people's work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too. Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. Some sports or games go back to thousands of years, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Both of them are just about a hundred years old. People are inventing new sports or games all the time. People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person's character. One learns to fight hard but fight fair, to win without pride and to lose with _ . From the passage we know that _ .

The largest campaign of killing rats in history is set to poison millions of rats on the sub-Antarctic island of South Georgia. Scientists say the campaign planned for 2013 and 2014 will restore beautiful South Georgia to the position it once held as the world's most important nesting sites for seabirds. It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment. "If we can destroy the rats, at least 100 million birds will return to their home on South Georgia," says Tony Martin, a biology professor at the University of Dundee who was invited to lead the project. South Georgia is by far the largest island to get rid of animals that destroy native wildlife after being introduced deliberately or accidentally by people. Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world. South Georgia is seven times the size of New Zealand's Campbell Island, currently the largest area ever killing rats. The successful war against Campbell Island rats was carried out in 2001 with 132 tons of poison dropped from five helicopters. "New Zealand pioneered the techniques for ridding islands of rats and in fact our operation on South Georgia is based on New Zealand's technology." Says Martin. "Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, in the Aleutian chain of the north Pacific." The second and third stages in 2013 and 2014 will involve dropping as much as 300 tons of poison from the air onto every part of the island where rats might live. It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months. "Ideally we'd do in winter but the weather makes that too risky," Martin says. The ecological payback will be priceless. But Martin says,... According to the passage, how did the rats appear on the sub-Antarctic island of South Georgia? A) They were attracted there by wildlife. B) They escaped there from Campbell Island. C) They were introduced there by sailors accidently. D) They were brought in by people deliberately.

Recently, another study has been carried out about who is the greatest American president. Sixty-five presidential historians took part in it and they judged the past forty-two American leaders based on ten qualities of leadership, which include public persuasion, crisis leadership, the management of economy, moral leadership and international relations. The historians also looked at administrative ability, relations with Congress, goal setting and pursuit of equal justice for all. Finally, the experts considered performance based on the historical period in which the president lived. The historians chose Abraham Lincoln as America's greatest president. He had also been named best president in a similar study in 2000. Abraham Lincoln was the only president in American history to lead the nation during the Civil War in the 1860s. He united the nation at last. And he took the first steps that destroyed the institution of slavery in America. Edna Medford is a professor of history at Howard University in Washington, D.C. She was an adviser on this study and the earlier one. She says Abraham Lincoln is seen to represent the values that the nation most honors like truthfulness, moderation and respect for human rights. The historians named America's first president, George Washington, as second on the list of greatest presidents. Franklin D. Roosevelt, Theodore Roosevelt and Harry Truman are next in that order. John F. Kennedy, the country's first Roman Catholic president, is sixth on the list. Like Abraham Lincoln, John F. Kennedy was murdered while in office. Among recent presidents, Ronald Reagan was named the tenth best president. Bill Clinton was rated fifteenth. And the historians rated former president George W. Bush as number thirty-six. His father, George H.W. Bush, did much better. He was rated as number eighteen. According to the recent study, a good president wouldn't _ . A) persuade the public to follow some rules B) take measures to deal with an economic crisis C) start a war between countries D) run after equal justice for the people

Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean. Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal. Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans. People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth. If too many sharks in one area are killed, that group of sharks may never return to normal population levels. . Which of the following words best describes the situation sharks are in? A) Good. B) Endangered. C) Powerful. D) Expensive.
