Today, the bicycle is the primary method of transportation for the human race. About 1.6 billion bicycles are in use around the world --- in big cities, along remote country lanes, and in the smallest villages ---and hundreds of millions of bikes are produced every year to meet the continuing demand for cheap wheeled transport.
Yet the bicycle is hardly a new vision of how humans move around. Historians speculate(猜测) about Leonardo da Vinci’s 1940s drawings and a 1580s stained glass window in England that appear to describe a two-wheeler. The first widely recognized two-wheeler in actual use, however, was the pedal-less Celerifere, a toy of the French upper class in the 1970s. The more famous Draisienne followed that toy in 1816, still without pedals. The front wheel could be steered, and this two-wheeler was eventually mass-produced in Europe, particularly in England. Ernest Michaux added cranks(曲轴) to the two-wheeler in 1855, which started a revolution in human transportation --- the Velocipede.
By 1870, complicated metal Velocipede were in production in Europe and the United States. Over time, they gave way to the “Ordinary” or high-wheeler. The Ordinary was the beginning of the heyday(全盛期) of bicycling. It was speedy and capable of long trips on poor roads, so it was soon in widespread use. At that time a skilled person might earn 25 cents an hour in wages, but a good Ordinary sold for $75 to $125, making it more expensive than building a house. Nevertheless, they sold at a furious pace.
Ordinaries had a big problem, however. When the front wheel came up against any obstacle that it could not roll over, the bike simply threw the rider headfirst onto the ground. Called a “header”, this characteristic problem inspired the “safety bicycle” in the 1980s. With two wheels of equal size, plus a roller chain(齿轮) transmission, the safety bicycle was with a slight adaptation, they attracted thousands of women to cycling. Many historians point to the safety bicycle as the beginning of women’s rights.
In England, in 1909, the Raleigh bicycle, equipped with a 3-speed hub, started to be produced. In the 1930s, British-built “lightweight” bicycles, suitable for the packed earth of country roads, were being imported into the United States. The early 1980s saw the creation of the “Freestyle” or trick bicycle. And in the late 1990s, the road bike and the mountain bike proved to be the dominant machines of the decade.
Today, the bicycle continues to be the most energy and cost-efficient transportation device in the world.What is the main idea of the first paragraph?

A sure way to destroy your chances of learning how to write skillfully is to believe that writing is a “natural gift” rather than a learned skill. People with such an attitude think that they are the only ones for whom writing is unbearably difficult. They feel that everyone else finds writing easy or at least tolerable. Such people often say, “I’m not any good at writing” or “English was not one of my good subjects.” They imply that they simply do not have a talent for writing while others do. The result of this attitude is that these people try to avoid writing, and when they do write, they don’t try their best. Their writing fails chiefly because they believe that they don’t have the “natural talent” needed to write. Unless their attitude changes, they probably will not learn how to write effectively.
A realistic attitude about writing must build on the idea that writing is a skill. It is a skill like driving, typing, or cooking; and, like any skill, it can be learned. If you have the determination to learn, you will develop your writing skills by practicing extensively.
Many people find it difficult to do the active thinking that clear writing demands. It is frustrating to discover how much of a challenge it is to transfer thoughts and feelings from one’s head onto a sheet of paper. But writing is not an automatic process: We will not get something for nothing — and we should not expect to. For almost everyone, skillful writing comes from hard work — from determination and sweat. The good news is that the skill of writing can be mastered, and if you are ready to work, you will learn what you need to know.Why do some people think writing is difficult?
| A．They have no time to practice writing. |
| B．They believe few people can write well. |

Scientists have discovered a special biological behavior in dolphins（海豚） that could lead to a treatment for late-onset diabetes（晚发的糖尿病） in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.
The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.
If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity（肥胖）.
The tissues of people with type 2 diabetes have become resistant to insulin（胰岛素）so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys（肾脏） and nerves and contribute to 5% of all deaths, according to the World Healthy Organization.
Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analyzed 1,000 blood samples（样本） from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism（新陈代谢）changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.
“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.What’s the main idea of the passage?
| A．Humans get some idea of treating diabetes from dolphins. |
| B．Dolphins can switch into a diabetic-like state overnight. |
| C．Humans can suffer the same disease as dolphins. |
| D．Dolphins should be fed regularly to avoid diabetes. |
The key to applying the finding to curing human diabetes lies in ____________.
| A．producing insulin in a larger amount |
| B．developing drugs from healthy dolphins |
| C．identifying a similar genetic pathway in human |
| D．analyzing more blood samples from hungry dolphins |
Which of the following statements is TRUE according to the passage?
| A．Scientists have found a similar genetic switch in humans. |
| B．More British people will suffer type 2 diabetes due to obesity. |
| C．2.2 million people with type 2 diabetes die in Britain every year. |
| D．Dolphins imitate diabetes to avoid a high blood sugar level. |
What will happen to dolphins if not fed for a night according to Venn-Watson?
| A．Their metabolism breaks down. |
| B．They become resistant to insulin. |
| C．Their heart and kidneys are damaged. |
| D．They keep high levels of blood sugar. |
Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries（传教士）built the church in 1791. It was the start of a special kind of neighborhood: the Mission District.
The area is a place with a long and varied history. One community member says that it’s important for people to understand the many levels of history in the neighborhood. He feels that this knowledge is a big part of understanding what it means to be a real San Franciscan.
One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. It’s easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music!
Juan Pedro Gaffney, the director of the Spanish Choir（唱诗班）of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively.
But it isn’t just its music that’s colorful and lively. Its art is full of life as well.
The local art community stays close to the area’s culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals （壁画）. Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, they’re something the community likes.
Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. “People see that they’re not so different from each other,” says one artist. “There are a lot of things that bind（捆绑）the immigrants through culture and tradition.”The underlined phrase “this knowledge” in Paragraph 2 refers to ____________.
| A．having memories of the Spanish missionaries |
| B．knowing the history of the Mission Dolores Basilica |
| C．realizing what it means to be a real San Franciscan |
| D．understanding the many levels of history in the neighborhood |
The author shows the multi-culture of the Mission District from the aspects of ____________.
| A．literature and sports |
| B．music and murals |
| C．buildings and clothes |
| D．customs and festivals |
It can be inferred from the passage that in the Mission District ____________.
| A．immigrants from different cultures live in harmony |
| B．Latin American music and foods are the most attractive |
| C．the Spanish Choir stands out in the competition of different cultures |
| D．new immigrants have to give up their own culture to be welcome |

The Great Gatsby is a 1925 novel written by American author F. Scott Fitzgerald that follows a cast of characters living in the fictional town of West Egg on Long Island in the summer of 1922.
Nick Carraway rents a small house in West Egg on Long Island, next door to the expensive house of Jay Gatsby, a mysterious millionaire who often holds extravagant（奢侈的）parties. Nick’s cousin, Daisy, and her husband, Tom, a college classmate of Nick’s, live in East Egg across the bay.
Nick later learns that Gatsby knew and fell in love with Daisy in 1917 and is still deeply in love with her. He spends many nights staring at her house across the bay from his house, hoping to recover their lost relationship one day. Gatsby’s extravagant lifestyle and wild parties are an attempt to impress Daisy in the hope that she will one day appear again at Gatsby’s doorstep. With the help of Nick, Gatsby and Daisy get in touch again. But after a short time, Tom forces the group to drive into New York City, saying that he and Daisy have a history that Gatsby could never understand. In addition, he announces that Gatsby is a criminal whose fortune comes from illegal activities. Daisy realizes that her allegiance（忠心）is to Tom, and Tom sends her back to East Egg with Gatsby, attempting to prove that Gatsby cannot hurt him.
When Nick and Tom drive home, they discover that Gatsby’s car has struck and killed Myrtle. Nick later learns from Gatsby that Daisy, not Gatsby himself, was driving the car at the time of the accident but Gatsby intends to take the blame anyway. Myrtle’s husband, George, arrives at Gatsby’s house and fatally（致命地）shoots both Gatsby and then himself.
Nick stages a small funeral for Gatsby with few coming to mourn the passing of his romantic dream. After that, Nick moves back to the Midwest, disillusioned（幻灭）with the Eastern lifestyle.
