单选题In 2014, older Americans fell 29 million times, leading to 7 million injuries, according to a report published last week. About 2.8 million cases were treated in emergency departments, and approximately 800,000 seniors went on to be hospitalized. More than 27,000 falls led to death. (76) And the problem is getting more and more serious. "Older adult falls are increasing and, sadly, often indicate the end of independence," said Dr. Tom Frieden. The falls are preventable, Frieden stressed. He said individuals, families and health care providers can take steps to resist the trend. Dr. Wolf-Klein is a medical professor in New York. She said one concern is that seniors who have experienced a fall alone at home don"t tell anyone. When that happens, prevention efforts don"t begin and they"re at risk for additional falls that lead to broken bones and brain injuries. "Elderly patients tend not to report falls to their families, or even doctors. A fall is a very frightening thing that you keep quiet about. They think if they mention it, they are afraid that they will move to a nursing home or need assistants to help out in the house," said Wolf-Klein. It"s also a status issue and may make someone feel that they"re weaker than they really are, she explained. When someone does fall and hurt themselves, they"re often never the same, Wolf-Klein said. "You can develop chronic (慢性的) problems. After a fall, a percentage of the population will never return to walking around. People used to taking the subway, now they"re in a wheelchair, or they may need help going to the bathroom. They become frailer and lose independence," she said.

单选题In sport the sexes are separate. Women and men do not run or swim in the same races. Women are less strong than men. That at least is what people say. Women are called "the weaker sex", or, if men want to please them, "the fair sex". But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men. A European woman can expect to live until the age of 74, a man only until he is 68. Are women"s bodies really weaker? The fastest men can run a mile in 4 minutes. The best women need 4.5 minutes. Women"s speeds are always slower than men"s, but some facts are surprising. Some of the fastest women swimmers today are teenage girls. One of them swam 400 metres in 4 minutes 21.2 seconds when she was only 16. The first "Tarzan" in films was an Olympic swimmer, Johnny Weissmuller. His fastest 400 metres was 4 minutes 59.1 seconds, which is 37.9 seconds slower than a girl 50 years later! This does not mean that women are catching men up. Conditions are very different now, and sport is much more serious. It is so serious that some women athletes are given hormone(荷尔蒙) injections. At the Olympics a doctor has to check whether the women athletes are really women or not. It seems sad that sport has such problem. Life can be very complicated when there are two separate sexes!

单选题Jim"s job is to keep his boss ______ of the latest development of that product in Europe.

单选题It is the world's fourth-most-important food crop, after maize, wheat and rice. It provides more calories, more quickly, using less land and in a wider range of climates than any other plant. It is, of course, the potato. The United Nations has hoped that greater awareness of the merits of potatoes will contribute to the achievement of its Millennium Development Goals, by helping to reduce poverty and promote economic development. The potato promoted economic development by supporting the Industrial Revolution in England in the 19th century. It provided a cheap source of calories and was easy to cultivate, so it liberated workers from the land. Potatoes became popular in the north of England, as people there specialized in livestock farming and domestic industry, while farmers in the south concentrated on wheat production. By a happy accident, the concentrated industrial activity in the regions where coal was readily available, and a potato-driven population boom provided ample workers for the new factories. Friedrich Engels even declared that the potato was the equal of iron for its "historically revolutionary role". In the form of French fries, served alongside burgers and Coca-Cola, potatoes are now a symbol of globalization. This is quite a change given the skepticism which first greeted them on their arrival in the Old World in the 16th century. They were variously thought to be fit only for animals, to be associated with the devil or to be poisonous. They took hold in 18th- century Europe only when war and famine meant there was nothing else to eat; people then realized just how useful and reliable they were. As Adam Smith, one of the potato's many admirers, observed at the time, "The very general use which is made of potatoes in these kingdoms as food for man is a convincing proof that the prejudices of a nation, with regard to diet, however deeply rooted, are by no means unconquerable." Mashed, fried, boiled and roast, a humble potato changed the world, and people everywhere should celebrate it.
