SECTION A  10 points

Directions: Read the following passage. Fill in the numbered blanks by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.

Many people believe they are supposed to drink eight glasses of water a day, or about two liters(升). Why? Because that is the amount of water they have been told all their life. But a recent report offers some different advice. Experts suggest people should obey their bodies: they should drink as much water as they feel like drinking.

The report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, which provides scientific and technical advice to the government and the public. The report contains some general suggestions. It says women should get about 2.7 liters of water daily and men about 3.7 liters. But wait-in each case, that is more than eight glasses.

There is one important difference. The report does not tell people how many glasses of water are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods.

As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need twice as much water as others do.

All this, however, does not answer one question. No one seems sure why people have the idea that good health requires eight glasses of water daily. It may have started with a misunderstanding.

SECTION B  4 points

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit.

Write your answers on your answer sheet.

It's one of the world's greatest mysteries - how did the ancient Egyptians build the pyramids? It's as worrying as the riddle of the Sphinx. And the truth is, no one really knows how they built the pyramids.

But amateur Egyptologist Maureen Clemmons has a theory. She thinks that kites may have been used to build the pyramids.

"If you look at the top center of every monument , you see wings," Clemmons said. "I think the Egyptians have been trying to tell us in pictures for 3000 years that this is how they built the pyramids."

Her idea - to build a pyramid, you control the desert wind using kites to lift the stones. She got a team of aeronautic engineers from Caltech to help her test the theory.

"At the beginning, we were very critical of her ideas but then we started to think more about it and we said, 'why not? let's try it,'" said Mary Gharid of Caltech.

The engineers worked out the math and designed a system of nylon ropes and pulleys (滑轮). Each pulley is four times the amount of weight a single kite can pull.

"So, we're using one kite in 15 mile per hour winds to lift up a three and half ton block," said Caltech student Emilio Castano.

Yesterday, in the Mojave Desert, they put their theory to the test using a nylon kite, three pulleys and an obelisk(方尖塔) that weighs nearly four tons. The wind speed had to be just right. And unimaginably, it worked. There was more than enough force to raise the obelisk. The total airtime is only twenty-five seconds. But the fact that it can be done doesn't necessarily mean that's how the ancient Egyptians did it. "There's absolutely no evidence (证据) for kites in ancient Egypt," said Professor Carol Redmount of UC Berkeley. "There's no evidence of pulleys as we know them today."
