回答下面的题目:American SportsThe United States is a sports-loving nation. Sports in Americatake a variety of forms: organized competitive struggles, which draw hugecrowds to cheer their favorite team to victory; athletic games,played forrecreation anywhere sufficient space is found; and hunting and fishing. Mostsports are seasonal, so that what is happening in sports depends upon the timeof year. Some sports are called spectator sports, as the number of spectatorsgreatly exceeds the number playing in the game.Baseball is the most popular sport in the US. It is playedthroughout the spring and summer, and professional baseball teams play wellinto the fall. Although no other game is exactly like baseball, perhaps the onemost nearly like it is the English game of cricket.Football is the most popular sport in the fall. The gameoriginated as a college sport more than 75 years ago. It is still played byalmost every college and university in the country, and the football stadiumsof some of the largest universities seat as many as 80, 000 people. The game isnot the same as European football or soccer. In American football there are 11players on each team, and they are dressed in padded uniforms and helmetsbecause 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 othercountries. Many Americans prefer it to football because it is played indoorsthroughout the winter and because it is a faster game. It is a very populargame with high schools, and in more than 20 states, state-wide high schoolmatches are held yearly.Other spectator sports include wrestling, boxing, and horseracing. Although horse-racing fans call themselves sportsmen, the accuracy ofthe term is questionable, as only the jockeys who ride the horses in the racescan be considered athletes. The so-called sportsmen are the spectators, who do"not assemble" primarily to see the horses race, but to bet upon theoutcome of each race. Gambling is the attraction of horse racing.Hunting and fishing are mainly favored by men, young and old,in the US.
根据下列材料,请回答下面的题目Look After Your VoiceOften speakers, at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth. First gently bite the edges of your tongue with your teeth. Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flows. Or you can imagine that you are Slicing a big juicy lemon and sucking the juice.Before you begin your talk, be kind to your voice, Avoid milk or creamy drinks which dry your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that you are losing your voice, stop talking completely. In the meantime, do not even talk in a low voice. Save your voice for your health. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If it is necessary , perhaps you can get some advice from a professional singer.What about drinking alcohol to wet your throat? I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking.Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, "We learn to skate in the summer and swim in the winter". Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.To solve the problem of dry mouths, one is advised to take cool milk.
回答下面的题目:UndergrOund Coal Fires Coal burning deep underground in China, India and Indonesia is threatening the environment and human life, scientists have warned. These large scale 51 blazes ( 火焰 ) cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can 52 ignite ( 点燃) forest fires, a group of scientists told the annual meeting of the American Association for the Advancement of Science in Denver. The resulting 53 of poisonous elements like mercury can also pollute local water sources and soils, they warned."Coal fires are a global disaster," said Associate Professor Glenn Stracher of East Georgia Collage in Swainsboro, USA. But 54 few people know about them.Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to 55 and under the right combinations of sunlight and oxygen, can trigger spontaneous ( 自发的 ) catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. 56 fires in China consume up to 200 million tons of coal per year, delegates were told. In 57 , the U.S. economy consumes about one billion tons of coal annually, said Stracher, 58 analysis of the likely impact of coal fires has been accepted for publication in the International Joomal of Acoal Ecology.. 59 underway, coal fires can burn for decades, even centuries. In the process, they release large 60 of greenhouse gases, poisonous fumes and black particles into the atmosphere.The members of the panel discussed the 61 these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to 62Ultimately, the remote sensing and other techniques should allow scientists to 63 how much carbon dioxide these fires are emitting ( 释放 ). One suggested 64 of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout ( 灌浆 ), which is designed to be pumped into the coal fire to 65 the oxygen supply.第51题应选:
