单选题 American Sports The United States is a sports-loving nation. Sports in America take a variety of forms: organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is found; and hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year. Some sports are called spectator sports, as the number of spectators greatly exceeds the number playing in the game. Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall. Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game of cricket. Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It is still played by almost every college and university in the country, and the football stadiums of some of the largest universities seat as many as 80000 people. The game is not the same as European football or soccer. In American football there are 11 players in each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. Basketball is the winter sport in American schools and colleges. Like football, basketball originated in the US and is not popular in other countries. Many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly. Other spectator sports include wrestling, boxing, and horse-racing. Although horse-racing fans call themselves sportsmen, the accuracy of the term is questionable, as only the jockeys who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do "not assemble" primarily to see the horses race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.

单选题Japanese Language Today If you want proof that the Japanese language is in decline, just Watch a few parliamentary debates and press conferences on Japanese TV. You won't see politicians talking about what can be done to improve language skills among the country's youth. Rather, you'll see government officials misusing their own language. Recently Prime Minister Keizo Obuchi(小泉纯一郎) called himself a person lacking vocabulay. It seems he's governing a nation of such people. Last May a group of university deans announced the results of a survey showing that a majority of Japanese college students have difficulty expressing themselves fully and clearly in their own language. Throughout Japan, ling juistic skills have been in a downward spiral for at least a decade. Young people who read less and watch more TV than ever before regularly stumble over old proverbs, miss the subtleties of polite expressions and even mistake one written character for another. Japanese is considered one of the world's most difficult languages. Grammar is complicated, and the meanings of words are multifarious (多种多样). There are also different kinds of written characters—ancient Chinese characters known as kanji (日文中的汉字) ,Japanese letters called hiragana and the characters used for foreign words. Many young people struggle with kanji, which are often used to express more ideas. Young people also lack familiarity with Western classics well known to their educated eiders. Many teachers blame video games and television for language problems. Others say that word processors are at fault. To use them, Japanese have to type in Roman letters, then select from a menu of written Japanese and Chinese characters. Since users aren't actually writing the words themselves, experts say it's easy to forget them. But technology is only part of the problem. Some say the real issue is an isolated generation. Young people nowadays don't seem to have conversion with elders who understand the language better. While Japanese educators haven't yet come up with a solution to the language problem, the public does seem ready to take action.

单选题Influenza (流感) Influenza has been with us a long time. According to some Greek writers (51) medical history,the outbreak of 41 2 B. C. was of influenza.
