It has been two years since China Daily last interviewed 31-year-old Zhang Chao．The micrograph enthusiast still wears the same hair style, even the same coat．
But one thing is very different: He's become a celebrity in cyberspace almost overnight, after his pictures, which show what the smog in Beijing looks like under his microscope, spread like a virus on China's major micro-blogging site Sina Weibo, since he posted them last Friday．Now the media is always interviewing him．
Zhang's apartment is on the eighth floor, which he says is perfect for capturing the thickest levels of smog．
As a Beijing native, Zhang explains his original purpose is to deconstruct Beijing's smog and expose its mystery．" People have higher and higher standards for the environment," he says," When I was a child, I was annoyed by the frequent sandstorms, so I feel Beijing's air seems much better now all in all because there are hardly any sandstorms in recent years．Now, we've noticed PM2.5, which has long been neglected．"
Although he graduated as a science major from Beijing Normal University, Zhang says it is difficult for him to give an exact definition of what smog is in Beijing. Under his scope, which magnifies（放大）the sample 1,000 times, the smog is found to contain minerals, fragments of animal fur and insects, seeds and burnt dust．But many are compounds, he says, which are more difficult to identify．
Zhang realizes that he may have disappointed the public because he can't show the inner construction of PM2.5 , today's most notorious(.臭名昭著的) element in smog. It is beyond the capacity of his microscope and camera to explore such tiny grains, " You cannot imagine how splendid the micro world is" ! says Zhang Chao.Zhang Chao has become a celebrity in cyberspace because_________.
| A．he has taken many pictures of smog |
| B．he is a micrograph enthusiast |
| C．he graduated from Beijing Normal University |

| B．give a detailed analysis of the smog |
| C．observe the smog carefully |
| D．emphasize the importance of the smog |
According to the text, which of the following is wrong?
| A．PM2.5 has long been ignored． |
| B．PM2.5 is an element in smog． |
| C．Under the scope the smog can be identified clearly． |
| D．In recent years there are less sandstorms in Beijing． |
From the passage we can infer that _____．
| A．Zhang Chao is interested in the micro world very much |
| B．Zhang Chao can't show the inner construction of PM2.5 |
| C．Zhang Chao was annoyed by the frequent sandstorms when he was a child |

The summer I was ten, my mother decided to bring us to the world of art. My brother and I were not very excited when we realized what my mother meant. What she meant was that we would have to spend one afternoon a week with her at the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting styles. It was almost as bad as being in school. Who wants to spend the summer thinking about artists when you could be with your friends at the swimming pool?
First we had to read about ancient Egyptians and their strange way of painting faces and then go to look at them at the museum. My 12-year-old brother thought this was so funny, but I was not interested. Later we had to learn about artists in the Middle Ages who painted people wearing strange long clothing. We had to look at pictures of fat babies with wings and curly (鬈曲的) hair and with no clothes on flying around the edges of paintings. I certainly couldn't see what was so great about art.
On our last visit to the museum, something happened when I saw a painting by a woman called Mary. In it, a woman was reading to a child. The colors were soft and gentle, and you could tell by the mother' s expression how happy she was just to be with the child. I couldn't stop looking at this painting ! I wanted to see every painting Mary had ever made! It was really worth looking at so many paintings to find a painter who could interest me so much.The aim of the mother' s plan was to _________.
| A．take them to visit the museum | B．introduce them to the world of art |
| C．ask them to read about artists | D．show them different painting styles |
What was the writer' s experience in the museum before the last visit?
| A．She came to feel her mother' s love. | B．She liked many paintings. |
| C．She hardly enjoyed herself. | D．She could understand the pictures of fat babies. |
What made the writer go through a change that summer?
| A．One of Mary's paintings. | B．A strange way of painting. |
| C．Artists in the Middle Ages. | D．Her mother' s instruction. |
From the text, we can see _________.
| A．the importance of curiosity | B．the effect of art |
| C．the value of learning | D．the power of family education |
Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined (限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic(器官的) disease that destroys brain cells.
Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking. Then the patient's memory begins to fail. He may forget dates, telephone numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Some of the scientists think a virus causes Alzheimer's disease. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.Alzheimer's disease ____________.
| A．a terrible part of the aging process | B．is an organic disease that affects young and old |
| C．can be cured by physical treatment | D．causes high fever |
All of the following are symptoms of Alzheimer's disease EXCEPT ____________.
| A．brain damage | B．difficulty in speaking | C．loss of sight | D．loss of the ability to walk |
According to the passage, which of the following may be a cause of Alzheimer's disease?
| A．Poisons produced by the brain. | B．Getting old. | C．A virus. | D．Lack of exercise. |
Going home for Christmas is a tradition of the holiday season. No matter where you may be the rest of the years, being at “home” with your family and friends for Christmas is a “must”. The Thanksgiving and Christmas holidays are the busiest times of the year at airports, train stations and bus stations. It seems that all America is on the move and Americans are on their way to spend the holidays with their loved ones.
This means that the house will be full of cousins, aunts and uncles that might not see each other during the year. Everyone joins in to help in the preparation of the festival. Some family members get to choose a Christmas tree to buy and bring home. Others decorate the house or wrap presents. And of course, each household needs to make lots of food!
At Christmas Eve gatherings adults have eggnog, which is made of cream, milk, sugar, eggs and brandy. Plenty ofeggnog or hot cocoa is on hand in colder climates for carolers, or people who go from house to house sing Christmas carols to their neighbors.
Long ago, each child hung a stocking, or sock, over the fireplace. Santa entered down the chimney and left candy and presents inside the socks for the children. Today the tradition is carried on, but the socks are now large red sock-shaped fabric bags still called stockings. Each child can’t wait to open his or her eyes to see what Santa has left in the stocking.
Giving gifts is a Christmas tradition. However, in recent years, more and more people have complained that Christmas is too commercialized(商业化) especially in large cities. Store owners begin advertising and decorating very early in hopes of selling more goods. Some people believe that the origin of Christmas has been lost.It is a traditional custom for Americans ____________.
| A．to buy Christmas trees and bring them to churches for Christmas |
| B．to drink beer on Christmas Eve |

Each child hung a stocking over the fireplace in order to____________.
| A．get some eggnog | B．have a look at Santa |
| C．get some candy and presents | D．get some money from his/ her parents |
The last paragraph wants to tell us that____________.
| A．giving gifts is a Christmas tradition | B．giving gifts is getting more and more commercialized |
| C．store owners hope to get more presents | D．people think there will be no Christmas in the future |

First the ground shook in Haiti, then Chile and Turkey. The earthquakes keep coming hard and fast this year, causing people to wonder if something evil (邪恶的) is happening underfoot.
It’s not.
While it may seem as if there are more earthquakes occurring, there really aren’t. the problem is what’s happening above ground, not underground, experts say.
More people are moving into big cities that happen to be built in quake zones, and they’re rapidly putting up buildings that can’t withstand (经受) earthquakes, scientists believe.
And around-the-clock news coverage (报道) and better earthquake monitoring make it seem as if earthquakes are ever-present.
“I can definitely tell you that the world is not coming to an end,” said Bob Holdsworth, an expert in tectonics (筑造学) at Durharn University in the UK.
A 7.0 magnitude quake in January killed more than 230,000 people in Haiti. Last month, an 8.8 magnitude quake--- the fifth-strongest since 1900—killed more than 900 people in Chile. And two weeks ago, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9, according to the US Geological Survey. This year is off to a fast start with 40 so far—more than in most years for that time period.
But that’s because the 8.8 quake in Chile generated a large number of strong aftershocks, and so many quakes this early in the year skews (扭曲) the picture, said Paul Earle, a US seismologist (地震学家).
Also, it’s not the number of quakes, but their devastating (破坏性的) impacts that gain attention, with the death tolls (死亡人数) largely due to construction standards and crowding, Earle added. “The standard mantra (咒语) is earthquakes don’t kill people, buildings do, ” he said.
There have been more deaths over the past decades from earthquakes, said University of Colorado geologist Roger Bilham. In an opinion column last month in the journal Nature, Bilham called for better construction standards in the world’s big cities.
Of the 130 cities worldwide with populations of more than 1 million, more than half are prone (倾向于) to earthquakes, Bilham said.
Developing nations, where populations are booming, don’t pay attention to earthquake preparedness, Bilham said.” If you have a problem feeding yourself, you’re not really going to worry about earthquakes.”
Another reason quakes seem worse is that we’re paying attention more. The Haiti earthquake quickly followed by the 8.8 in Chile made everyone start to think.
But it won’t last, said US disaster researcher Deniis Mileti. “People are paying attention to the violent planet we’ve always lived on,” Mileti said.” Come back in another six months if there has been no earthquakes, most people will have forgotten it again. ”

Being considered a leader in our society is indeed of high praise. Leadership means power, commands, respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can’t be easily swallowed down. They must be carefully cultivated.
Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you ) get others to follow?
Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that’s never forgotten.
Giving credit is more effective than even the most constructive criticism (批评), which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees. “Catch people doing something right!” he says. Then tell everyone about it.
Take informed risk. (冒险). “The best leaders know that taking a risk is not a thoughtless exercise,” says management adviser Marilyn Machlowitz. “Sky divers don’t go up in an airplane without checking the parachutes beforehand.”
Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail --- and not die a thousand deaths. Pick yourself up and start all over again.
Encourage enthusiasm.（热情） “When people understand the importance of work, they lend their mental strengths,” says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That’s a great force! Is this the best way to create excitement? Be enthusiastic yourself - You will be followed by everyone.
