As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is important for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not such a bad thing as it is often supposed to be. A certain amount of stress is vital（important）to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can stand depends very much on the individual. Some people are not afraid of stress; others lose heart at the first sign of unusual difficulties. When faced with stress, in whatever form, we react both chemically and physically. In fact we make choice between “flight or fight ” and in more primitive（原始的）days the choices made the difference between life or death. The crises（危机）we meet today are unlikely to be so extreme, but however little the stress, it involves the same reaction. It is when such a reaction lasts long, through continued suffering from stress, that health becomes endangered. Since we cannot remove stress from our lives （it would be unwise to do so even if we could）, we need to find ways to deal with it. According to the passage, the most important character of a good manager is ______.
| A．strong will to hold out stress | B．having control over performance |
| C．high sense of responsibility | D．knowing the art of relaxation |

| B．Stress is always harmful to people’s health. |
| C．We can find quite a few ways to avoid stress. |
| D．Different people can bear different amount of stress. |
According to the passage, the right attitude towards stress is to______.
| A．find some relaxation | B．regard it as a vital motivation |
| C．face it and overcome it | D．avoid it |
The greatest artistic creative geniuses I've ever seen, have been those who can turn garbage into art. Not just gluing together junk, but really making waste into something unique, cool, and well, something you, d put into your home for instance. There's something to be said about recycling of those items we commonly throw away.
The ability to take trash and garbage and turn it into art, or something intriguing that is fascinating to look at is a skill all of its own. I have often said that the true geniuses of our time, that is to say the creative genius artists of our era, are those who can do this-creating art that can command a high price tag from junk. 0ver the years while traveling through the United States I had stopped into museums in many parts of the country.
Some of the best art I've ever seen in my life has come from garbage, trash, or junk that has been reworked and recycled into something spectacular. Best of all the artists don't spend much on material costs, therefore it is mostly profitable. In fact they are using their minds to do a lot with very little. Just think if we all used our minds to do this, how little we might actually throw away, and how more efficiently we could run our factories, production, and even households.
After all, anything that is not used is waste, and it is thrown away. It ends up in a landfill, or a dump somewhere, and eventually it decays in the soil, causing perhaps ground water pollution. However, if we can rework these items for a couple of more rounds, and waste less, then we are providing efficiency for our civilization, and that's a good thing. Any artist who can do this is not only one caring the environment, but also one with humanity, and using his brain power and creative genius to make us all better. What would be the best title for the passage?
| A．Garbage in art out |

Twelve years ago, a young traveler named Rhett Butler from San Francisco, California, visited the Sabah rain forest on Malaysian Borneo. In one area of the rain forest, he watched a bird flying through the trees. The beautiful sight left quite an impression on him. But weeks later, back home, Rhett Butler got the news that trees had been cut down in the area he visited.
That experience led Rhett Butler to begin writing a book about rainforests and the threats to their existence. But he did not publish the book. Instead, in 1999，he used his research for the book to create a website. The site is Mongabay, com. His purpose was to inform the public about tropical rain forests. But the subject quickly developed. As a former businessman , he became a respected writer of science and environmental stories.
The popularity of Mongabay. com attracted advertisers. Small ads on the site pay for its operations. Mongabay. com has grown and led to other sites. For example, there is a site for children which is called kids, Mongabay. com. Another one, Wild Madangascar. org, is also about the island nation that Rhett Butler calls his favorite place.
To keep his website going, he travels around the world on several major trips each year. His working tools are a laptop computer, cameras and sometimes diving equipment. He often calls on experts for information. For example, he interviewed Alison Jolly, a top experts on lemurs (狐猴）. He interviewed Rodney Jackson, a biologist who established the Snow Leopard Conservancy.

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 in Northern 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 factors. Working back-ward, the scientists concluded that the first milk-drinkers 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 be-fore. Which of the following is the proper order of events according to the passage?
a. Their children were able to digest milk as adults.
b. They got sick from the milk.
c. Some people got a mutation in their genes.
d. Some people tried drinking milk from animals.
e. Some people started to drink milk from animals on a regular basis.
| A．c→d→b→e→a | B．d→e→b→c→a |
| C．d→b→e→c→a | D．e→d→b→c→a |

Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist's nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats.
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after eating is still the best way to fight cavities. What is the main purpose of this passage?
| A．To discuss how cavities can be treated. |
| B．To point out the problems with Halloween celebrations. |
| C．To tell parents what sweets are less damaging to their children's teeth. |
| D．To teach parents the meaning of Halloween candies for their children. |
Why are hard candies especially bad for teeth?
| A．They may break the child's teeth. |
| B．They contain too much sugar. |
| C．They help bacteria to produce tannins， |
| D．They stay in the mouth for a long time. |
According to the passage, which of the following is a better choice for Halloween treats?
A. Chocolate. B. Crackers.
C, Raisins. D. Potato chips. According to the passage, which of the following is true of tannins?
| A．They are produced when the bacteria digest the food. |
| B．They help to get rid of some bacteria in the mouth. |
| C．They help chocolate to dissolve more quickly. |
| D．They destroy the surface of the teeth. |
