Many people believe they are supposed to drink eight glasses of water a day, or about two liters. 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.

Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.
But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out or need to be pulled, an older person might need dentures.
Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.
Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked（浸泡） in denture solution when not in the mouth.
Dentures are important for the old because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.
People usually lose their permanent teeth due to periodontal disease（牙周炎）, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth problems.If one of your baby teeth falls out, you ________.
| A．should have a false tooth fixed in its place |
| B．have to put it under your pillow at once |
| C．will gain a permanent tooth in future |
| D．can exchange it for some money |
A person wearing dentures ________.
| A．should brush them with a special denture brush every few days |
| B．will take a very long time to adjust himself or herself to them |
| C．will experience unpleasant feelings at the beginning of fixing them |
| D．should use denture solution to soak them in his or her mouth |
Which of the following is NOT true according to the passage?
| A．Partial dentures can prevent the remaining teeth from changing position. |
| B．Old people will find it hard to smile, talk, and eat properly without teeth. |
| C．A person’s teeth will possibly get loose if diseases strike his gums. |
| D．It is hard for a person to wear dentures if all his teeth have fallen out. |
What does the underlined word “weird” mean in the fifth paragraph?

Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Eco-passages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals like salamanders(火蜥蜴) and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass!The writer uses the example of “ocelots” to show that _______.
| A．wild animals have become more dangerous |
| B．the driving condition has improved greatly |
| C．the measure for protecting wildlife fails to work |
| D．an increasing number of animals are killed in road accidents |
From the story, we know an eco-passage is ________.
| A．an underground path for cars |
| B．a path for animals to cross the road |
| C．a bridge for animals to get over a river |
| D．a fence built for the safety of the area |
When the writer says that “animals seem to be catching on”(Para. 6), he means ________.
| A．animals begin to learn to use eco-passages |
| B．animals begin to realize the dangers on the road |
| C．animals are crossing the road in groups |
| D．animals are increasing in number |
The writer asks visitors and drivers to look around when traveling because ________.
| A．they may see wild animals in the park |
| B．wild animals may jam the road |
| C．they may see wild animals on eco-passages |
| D．wild animals may attack cars |

In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he discovered that some of his wheat was lying flat on the ground. The flattened (变平的) wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots (点). During the following years, farmers in England found the strange circles in their fields more and more often.
The circles are called “crop circles” because they appear in the fields of grain—usually wheat or corn. The grain in the circles lies flat on the ground but is never broken; it continues to grow, and farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September.
At first, people thought that the circles were a hoax. Probably young people were making them as a joke, or farmers were making them to attract tourists. To prove that the circles were a hoax, people tried to make circles exactly like the ones that farmers had found. They could not do it. They couldn’t enter a field of grain without leaving tracks, and they couldn’t flatten the grain without breaking it.
Many people believe that beings from outer space are making the circles to communicate（交流）with us from far away and that the crop circles are messages from them.
Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a downward rush of wind leads to the formation of the circles—the same downward rush of air that sometimes causes an airplane to crash (坠毁). Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations: crop circles often appear in formations, like the five-dot formation. It is hard to believe that any natural force could form those.In the summer of 1978, an English farmer discovered in his field that ________.
| A．some of his wheat had been damaged |
| B．his grain was growing up in circles |
| C．his grain was moved into several circles |
| D．some of his wheat had fallen onto the ground |
According to the text, the underlined part “a hoax” (line 1, para. 3 ) probably means ________.
| A．an action made to fool people |
| B．a special way to plant crops |
| C．a research on the force of winds |
| D．an experiment for the protection of crops |
Which of the following may prove that the crop circles are not made by man？
| A．The farmers couldn’t step out of the field. |
| B．The farmers couldn’t make the circles round. |
| C．The farmers couldn’t leave without footprints. |
| D．The farmers couldn’t keep the wheat straight up. |
