New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”（体重指数） or BMI. This is a measurement of body fat as a ratio（比率） of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes（糖尿病）.According to the new findings, the researchers found that __________ .
| A．People with high obesity have a lower risk of early death than people with low obesity |
| B．People with overweight have a greater risk of early death than people of normal weight. |
| C．People with mild obesity are less likely to die than people of normal weight. |
| D．People with obesity live much longer than people of normal weight. |

It is true that good writers rewrite and rewrite and then rewrite some more. But in order to work up the desire to rewrite, it is important to learn to like what you write at the early stage.
I am surprised at the number of famous writers I know who say that they so dislike reading their own writing later that they even hate to look over the publishers’ opinions. One reason we may dislike reading our own work is that we’re often disappointed that the rich ideas in our minds seem very thin and plain when first written down. Jerry Fodor and Steven Pinker suggest that this fact may be a result of how our minds work.
Different from popular belief, we do not usually think in the works and sentences of ordinary language but in symbols for ideas (known as ‘mentalese’ ), and writing our ideas down is an act of translation from that symbolic language. But while mentalese contains our thoughts in the form of a complex tapestry (织锦)，writing can only be composed one thread at a time. Therefore it should not be surprising that our first attempt at expressing ideas should look so simple. It is only by repeatedly rewriting that we produce new threads and connect them to get closer to the ideas formed in our minds.
When people write as if some strict critics (批评家) are looking over their shoulder, they are so worried about what this critic might say that they get stuck before they even start. Peter Elbow makes an excellent suggestion to deal with this problem. When writing we should have two different minds. At the first stage, we should see every idea, as well as the words we use to express it, as wonderful and worth putting down. It is only during rewrites that we should examine what we excitedly wrote in the first stage and check for weaknesses.What do we learn from the text about those famous writers?
| A．They often regret writing poor works. |
| B．Some of them write surprisingly much. |
| C．Many of them hate reading their own works. |
| D．They are happy to review the publishers’ opinions. |
What do people generally believe about the way human minds work?
| A．People think in words and sentences. |
| B．Human ideas are translated into symbols. |
| C．People think by connecting threads of ideas. |
| D．Human thoughts are expressed through pictures. |
What can we conclude from the text?
| A．Most people believe we think in symbols. |
| B．Loving our own writing is scientifically reasonable. |
| C．The writers and critics can never reach an agreement. |
| D．Thinking and writing are different stages of mind at work. |
A volcanic eruption in Iceland has sent ash across northern Europe Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.
Grimsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier(冰川) of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer(层)of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava(岩浆) from the volcano then comes up to the surface. This is exactly what happened today.
Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. according to KLM, one of Europe’s biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane’s engines, causing damage to the plane.
The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp. Glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them from eating ash—covered grass to the sharp object.What makes Grimsvom different from other volcanoes?
| A．It is below ice. |
| B．It lies under the sea |
| C．It is the largest volcano |
| D．It is lava affects the airlines |
What keeps Grimsvom still?
| A．The slow flow of water. |
| B．The low water temperature. |
| C．The thick glacier. |
| D．The water pressure. |
Which of the following is the result of the volcanic eruption?
| A．People stop traveling in Europe. |
| B．Airlines suffer from the loss of planes. |
| C．It becomes dangerous for animals to eat outside. |
| D．Farmers have lost many of their animals. |

Listen to her. When people feel sad, they often have the feeling of needing to be heard. So, listen carefully to what she is saying and do nothing else. Your friend will surely thank you for being the shoulder she can cry on.
Once you are done with listening, you can offer some advice or remain silent and let her feel everything and let it all out by crying. As a friend, you might think you should give her some advice. But if you have no idea about what to say, just remain silent and be there for her.

The Eiffel Tower was built in 1889, in memory of the 100th birthday of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 suggestions that were handed in, Gustave Eiffel’s was chosen.
However, at first, it was not well accepted by all and a group of people — including many well-known writers and painters at that time — were fiercely against its design.
Being about 300 meters in height, and 7,000 tons in weight, it was the world’s tallest building until 1930. It was a great project for France. 300 workers took two years to build it. It isn’t an ordinary building, since it is almost made of steel. For example, its body moves around at most 12 cm in heavy wind. Moreover, its height changes up to 15 cm according to the temperature.
It was almost destroyed in 1909, but was saved because of its antenna(天线), which is used for communication at that time. Beginning in 1910 it became part of the International Time Service. French radio and French television have also made good use of its height.
The Eiffel Tower has also seen a few strange things. In 1923, a journalist rode a bicycle down from the first level of it. And in 1954, a mountain climber climbed on top of it and tried to measure its exact height.
Anyway, although its birth was difficult, it is now well accepted all over the world. It has been considered as one of the symbols of Paris. The passage mainly tells us ________.
| A．the history of the Eiffel Tower |
| B．some information about its design |
| C．what the Eiffel Tower was used for |
| D．how it became one of the symbols of Paris |

| A．Many people couldn’t accept the Eiffel Tower at the beginning. |
| B．It was the world’s tallest building for hundreds of years. |
| C．A journalist rode down from the Eiffel Tower in 1954. |
| D．The Eiffel Tower was saved because of its height. |
The French Revolution took place in _______.
| A．1889 | B．1923 | C．1789 | D．1930 |
When students and parents are asked to rate subjects according to their importance, the arts are unavoidably at the bottom of the list. Music is nice, people seem to say, but not important. Too often it is viewed as mere entertainment, but certainly not an education priority(优先). This view is shortsighted. In fact, music education is beneficial and important for all students.
Music tells us who we are because music is an expression of the beings who create it, it reflects their thinking and values as well as the social environment it comes from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity as a society.
Music provides a kind of perception (感知) that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts explore the emotive (情感的) meaning of the same phenomenon. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.
The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other .They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses.
Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebrations, the meaning and value of peace and love.
So music education is far more necessary than people seem to realize.According to paragraph 1, students.
| A．regard music as a way of entertainment |
| B．disagree with their parents on education |
| C．view music as an overlooked subject |
| D．prefer the arts to science |
In Paragraph 2, the author uses jazz an example to.
| A．compare it with rock music |
| B．show music identifies a society |
| C．introduce American musical traditions |
| D．prove music influences people’s lifestyles |
According to the passage, the arts and science.
| A．approach the world from different angles |
| B．explore different phenomena of the world |
| C．express people’s feeling in different ways |
| D．explain what it means to be human differently |
What is the main idea of the passage?
| A．Music education deserves more attention. |
| B．Music should be of top education priority. |
| C．Music is an effective communication tool. |
| D．Music education makes students more imaginative. |
