It will be hot—hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool.
Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(织物) designed with hot weather in mind.
“Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we're taking the warm out of warm up. It's like pre-cooling.”
Experts are predicting(预测) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).
Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures. Drinking lots of water will help athletes keep cool, but humidity(湿度) remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸发),resulting in dehydration(脱水) without the cooling.
“Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder,” said Sleivert.1.The passage mainly tells us that _______.A.why it is very hot in AthensB.the hot weather is a big problem for Olympic athletesC.how important science is to every athleteD.the Olympics will be put off because of the hot weather2.The underlined sentence “other competitors will be pushing their limits during high temperatures”in the fifth paragraph means _______.A.Olympic athletes will put off their competition timeB.some events in the Olympics will have to be put forwardC.competitors can't reach their limits in the hot weatherD.competitors will have to try their best to compete under any condition3.The following things will be likely to happen in the hot weather EXCEPT _______.A.dehydrationB.being sleepyC.that the blood in the body can become less and lessD.that the body's ability to cool down is weakened
