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. The passage mainly tells us that _______.
| A．why it is very hot in Athens |
| B．the hot weather is a big problem for Olympic athletes |
| C．how important science is to every athlete |
| D．the Olympics will be put off because of the hot weather |
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 time |
| B．some events in the Olympics will have to be put forward |
| C．competitors can't reach their limits in the hot weather |
| D．competitors will have to try their best to compete under any condition |
The following things will be likely to happen in the hot weather EXCEPT _______.
| A．dehydration |
| B．being sleepy |
| C．that the blood in the body can become less and less |
| D．that the body's ability to cool down is weakened |

None of our early ancestors could digest milk as adults because their bodies never had to ----milk drinking simply wasn’t an option. As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives.
Scientists now know of a milk-related mutation ( 变异) in our genes -- the chemical instructions for life that we carry in almost every cell in our bodies. People who have a mutated form of one particular gene can drink milk just fine. People without the mutation tend to get sick from milk.
To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation today. Patterns are striking.
Most adults in Northern and Central Europe are able to digest milk -- and they do. Cheese and butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England. Because European settlers dominated North America, most people here can handle milk just fine, as well. That may explain why ice cream is such a popular dessert in the United States.
In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea (腹泻) and other stomach problems. (That’s why you won’t typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native
Americans are also unable to digest milk.
Based on these genetic patterns, scientists have long thought that- milk drinking started inNorthern Europe, where dairy is an institution and the milk-digesting mutation is everywhere.
A recent study painted a different picture. With a computer medal, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factor. Working backward, the scientists concluded that the first milk-thinkers lived in Central Europe around what’s now Hungary about 7,500 years ago. The practice didn't start farther north, as scientists had thought before.

In the year 480 BC the Greek allies (联军) faced invasion by the King of Persia, Xerxes, who commanded a huge army of about half a million men. When the Persian army marched into northern Greece, the Greek states, led by Athens and Sparta, were ill equipped to deal with the threat. The Persians were well supplied with food and weapons. Their army included infantry, cavalry, and a large navy. It seemed that they would easily defeat the Greeks.
The Greek allies decided to send 10,000 men northwards to slow down the Persians, while the rest prepared to defend their homelands. A group of 300 best Spartan soldiers were chosen to lead the force going north, with Leonidas in command. Leonidas realized that the only hope of slowing the Persians would be to block the narrow passage of land at Thermopylae. The Pass of
Thermopylae was the route between the mountains and the sea, and was so narrow that only a few men could get through at a time.
When the Persian army arrived at Thermopylae, they found Leonidas' tiny army opposing them. The Persians attacked, but could not get through. They attacked again and again, but each time they were driven back by the Greeks, led by the fearless Spartans. Leonidas' plan worked well until a Greek traitor called Ephialtes went m Xerxes. He told the Persian king about a goat's path in the mountains that would take the Persian army past Thermopylae. When Leonidas saw the enemy crossing the mountains, he realized that he could no longer hold Thermopylae. He sent all the Greek soldiers except the 300 Spartans back to their homelands.
The Spartans waited for the 500,000 Persians at the goat’s path. Although hopelessly outnumbered, the Spartans fought bravely. They all died, but the other Greeks were able to get home to strengthen the defenses.

Nick Campbell sat at the side of the road and wondered what to do next. He looked at the second-hand Harley Davidson he’d bought from a back-street garage back home in Miami at the beginning of his trip six weeks before.
For years he had dreams of crossing the United States from east to west by motorbike and he’d finally decided that it was now or never. He’d given up his job, sold his car and set off for the journey of his dreams. He’d been lucky, or so he thought, to find this old Harley Davidson and had bought it for a very reasonable price------it had cost him just $600. But five kilometers from Atlanta, he had run out of luck. The motorbike had broken down.
He pushed the bike into town and found a garage. The young mechanic told him to leave the bike overnight and come back the next day. The following morning, to his surprise, the man asked if the bike was for sale. “Certainly not,” he replied, paid his bill and hit the road.
When he got to Kansas the old machine ran out of steam again. This time Nick thought about selling it and buying something more reliable, but decided to carry on. When the bike was going well, he loved it.
However, in Denver, Colorado the bike broke down again so he decided to take it to a garage and offer it for sale. The mechanic told him to come back in the morning.
The next day, to his amazement, the man offered him $2,000. Realizing the man must be soft in the head, but clearly not short of money, Nick asked for $ 3,000. The man agreed and they signed the papers. Then the mechanic started laughing. In fact it was several minutes before he could speak and when he could he said, “That’s the worst deal you’ll ever make, boy."
He removed the seat. On the underside was the inscription (铭文):
'To Elvis, love James Dean. '

A. clever B. crazy C. honest D. kind
60. At the end of the story, Nick must have felt very __________.
A. sorry B. delighted C. excited D. moved
Do you wake up in the morning dreading the moment that your feet have to hit the floor for you to get ready for work? If that’s the case, join most of Americans. Very few people wake up to that annoying alarm clock and spring out of bed excited about having to go to work.
As if that were not enough, most of us have to fight traffic getting there, usually an hour’s drive. Then, when we get to work, we have to fight with unruly co-workers or a nagging boss. And to make matters worse, you have to fight the same traffic going in the opposite direction just to get back home.
Making dinner, fixing plates, eating and then straightening up afterwards is a job within itself. If that sounds like your life, you probably have a J-O-B. you know what J-O-B stands for? Just Over Broke, that’s what! With a job, most Americans are living paycheck-to-paycheck and hating every minute of it. I know because I was doing the same thing: trading time for money. And, I came to a conclusion that it stinks (糟糕透了)! Big time!
Looking around at my co-workers, friends and relatives, I saw that they were all doing the same thing I was doing. They were complaining about the same things I was complaining about : not having enough time or money. And, I decided that I wanted to do something different.
So, I started a home-based business. There are several to choose from. The extra income has done so much for our family. We can vacation more. We have been able to give more. And, we’ve even been able to do something calling save! It’s been amazing.
Therefore, if you’re sick and tired of being sick and tired, it’s time you make a change, too. The definition of insanity (疯狂) is doing the same thing over and over and expecting different results. I know you aren’t stupid. If you continue to do what everyone else is doing: trading time for money, you’re going to keep getting what everyone else is getting: being broke and not having the time to do what is really important to you.
Do your due diligence. Find a home-based business that works well for you. Go to work, and live the life you’ve always imagined!According to Paragraph 1, which of the following statements is TRUE about most Americans?
| A．Most Americans are excited to go to work every day. |
| B．Most Americans are used to sleeping in the morning. |
| C．Most Americans are tired of having to go to work every morning. |
| D．Most Americans have alarm clocks to wake them up in the morning. |
By writing the first three paragraphs, what feeling does the writer express?
| A．Regret. | B．Joy. | C．Pride. | D．Dissatisfaction |
What does “something different” in Paragraph 4 refer to?
| A．To set up a business at home. | B．To complain about life and work. |
| C．To spend more time on holidays. | D．To resign from the former job and get a new one. |
