Given that many people's moods (情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drug store of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates.its founder is Chris Lee who grew up at his parents' corner store with one hand almost always in the jar of sweets.
If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored(味道)chocolates.
The CRF's produce is "green". made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The Exotic Series一with Sichuan pepper, red bean (豆).cheese and other flavors一also does well and is fun to taste. And for chocolate snobs，who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.What is good about chocolate?
| A．It serves as a suitable gift. |
| B．It works as an effective medicine. |
| C．It helps improve the state of mind. |
| D．It strengthens business relations. |
Why is Chris Lee able to develop his idea of the CRF?
| A．He knows the importance of research. |
| B．He learns form shops of similar types. |
| C．He has the support of many big names |
| D．He has a lot of marketing experience. |
Which line of the CRF produce sells best?
| A．The Connoisseur Series. |
| B．The Exotic Series. |
| C．The Alcohol Series. |
| D．The Sichuan Series. |
The words "chocolate snobs" in Paragraph 3 probably refer to people who
| A．are particular about chocolate |
| B．know little about cocoa beans |
| C．look down upon others |
| D．like to try new flavors |
【原创】Writing a children’s story requires a vivid imagination, good writing, creativity and the ability to put yourself into the mind of a child. For many writers, writing children’s books successfully will require some effort to step back into the shoes of the very young and to see the world from a very fresh and curious perspective. For those who are always young-at-heart, writing children’s stories can be a very satisfying job. And if you are a child author reading this article, these characteristics will be second nature to you but you will still benefit from these steps on how to write a children’s story.
Brainstorm story ideas. The story is perhaps the most important aspect of a good book. Consult some of your favorite books(children’s or not) for an example. Choose a story that fits your interests and talents, such as action, fantasy, or mystery. Smaller children enjoy stories with a play on words or a repeated phrase.
Develop your characters. In order to have a good story, you need some interesting characters. Who is the main character in the story? Is there more than one? Are the characters humans, animals or fantasy creatures, or do they include elements of all three? Before you begin, it is best to make an outline of the characters and how they fit into the story.
Add some pictures. Everyone loves pictures. They can add to the interest level of the story and make it easier to follow. You may like to include a few funny cartoons or pictures in your story. Make sure that you use bright, happy colors or dark, sad colors, depending on the mood of a story.
A children’s story doesn’t need to be realistic! That is the difference between children’s and adult books. Of course you can write about a talking goose. Sure you can write about a human with a dog’s head and three legs. While children can enjoy this, adults cannot very often just let the story flow over them.What is the text mainly about?

【原创】The first theories and experiments with cloning began in the late 1880s as scientist sought to prove their theories about how the genetic material inside cells worked. Discoveries about the nature of DNA in the 1940s made it possible for cloning experiments to progress. In 1944 it was discovered that genetic information for each cell was kept in the cell’s DNA. When Oswald Avery found this genetic information, it gave scientists new ways to try to clone animals by using that genetic blueprint（生物细胞的模型）.
The first cloned animals were northern leopard frogs that were cloned by Thomas J. King and Robert Briggs in 1952. King and Briggs believed, based on their clones, that young cells were more practical for the cloning process. Cells that were taken from adults resulted in abnormally developed tadpoles(蝌蚪). The next successful cloning experiments also resulted in cloned frogs. John Gurdon cloned South African frogs in 1962. His use of adult cells disproved the previous theory that only young cells could be used in the cloning process with success.
While animal cloning had been the focus of cloning experiments, the 1960s also saw other types of cloning. In 1964, F. C. Steward took an adult root cell from a carrot plant and successfully cloned the plant. Throughout the rest of the 1960s, scientists continued to clone frogs and to discover more about DNA. The first gene was discovered in 1969.
In 1977, the first cloned mice embryos were created. The first mammal was cloned in 1984. The cloned sheep was quickly followed in 1985 with cloned cattle embryos. A cow clone was created in 1986 and several calves in 1993. That same year, human embryos were cloned for the first time. In 1995 and 1996, sheep were cloned, including the famous Dolly.The first paragraph serves as a(n) __________________________.

【原创】“Will I be able to work until I’m 70?” Those were my first words when I learned in 2014, at the age of 50, that I had Parkinson’s disease. I had not planned for that question to pop out of my mouth, but it did. Perhaps I was worried about my money. The size of my retirement account makes early retirement seem impossible. But mainly I think I asked that question because work, for better or worse, has become central to my identity. The idea that my career as a historian would end soon felt truly disturbing.
As professors, we often complain about our jobs: we teach too much, we are paid too little, and the library needs more books. But I can’t imagine a better career. We teach young people, and we find the time to read and write about topics we love. We receive a degree of respect. Even my doctor calls me “Professor”.
And, most importantly, we have relative job security. When I received my diagnosis, my question about keeping my job was not ridiculous. In a market-based social system, the threat of job loss is terrifying. Imagine the pressure faced by a Parkinson’s sufferer with no job security. It could be disastrous for someone who needs manual dexterity at work, such as a construction worker.
In contrast, I am lucky: I have tenure(终身职位), which gives me a feeling of security that even popular entertainers may lack. Tenure does not guarantee me a job as long as I can perform y duties.
Will I be able to work until I’m 70? I think so. I know that my family and I will face new challenges, but I don’t expect a decline in my job performance. My students may find my appearance a bit odd, but if they do, then that will be a “teachable moment”.What did the author worry about first when he learned he was ill?
| A．He didn’t have enough money for an operation. |
| B．The disease would ruin his career. |
| C．He wouldn’t live until the age of 70. |
| D．He would be forced to retire early. |
According to the passage, which of the following statements is TRUE?
| A．Professors always complain about their jobs. |
| B．Professors have no time to do anything else but teach. |
| C．The author doesn’t know what he would do if he were not a professor. |
| D．The author thinks he is respected by others because of his work. |
The underlined phrase in the third paragraph, “manual dexterity” probably means _____________.
| A．the ability to use one’s hands |
| B．the ability to see clearly |
| C．the ability to use one’s mind |
| D．the ability to solve problems |
The best title for this passage is _________________________.
| A．Losing My Career to Illness |
| B．The Threat of Job Loss |

【原创】Children whose mothers were exposed to higher levels of phthalates(酞酸盐), common chemicals in consumer products, in late pregnancy tend to score lower than other kids on intelligence tests at age seven, according to a new study.
Some soaps, nail polish, hairspray, shower curtains, raincoats, car interiors and dryer sheets contain phthalates, which are used as so-called plasticizers, or softening agents.
At present, the Food and Drug Administration does not have evidence that phthalates as used in cosmetics pose a safety risk, but six types of phthalates are currently banned from children’s toys.
Researchers followed 328 New York women in low-income communities from pregnancy until the child was seven years old. When the children were seven, they completed an intelligence test measuring four areas of mental functioning. The mothers’ levels of two of the phthalates - DnBP and DiBP - during pregnancy were associated with childhood intelligence: As phthalate levels went up, child IQ tended to go down.
“With observational studies, there is always the chance that the results may be in part explained by an unmeasured factor that we haven’t yet considered,” said Stephanie Engel, associate professor of epidemiology（流行病）from the University of North Carolina.
“I would characterize this study as thorough and high quality, and the results concerning,” said Engel, who was not involved in the work. “But there needs to be more research in this area before firm conclusions can be drawn.”
“Nevertheless, It is clear that there needs to be a serious discussion in the scientific and policy communities about whether the evidence is strong enough yet to warrant widespread policy changes, not just on the basis of this study, but also including a range of childhood health outcomes that have already been reported in the literature,” Engel said.
“Although there are no regulations on phthalate exposure during pregnancy, it would be wise for expectant mothers to avoid microwaving food in plastic, avoid scented products, and as much as possible store foods in glass instead of plastic,” she said.According to the passage, the new study is about ___________________________.
| A．the interaction between a pregnant woman and her unborn baby |
| B．how phthalates taken in by a pregnant woman affect her baby |
| C．why children’s IQ is different at the age of seven |
| D．the usage of common chemical in consumer products |
Which of the following statements is TRUE?
| A．Researchers chose 328 pregnant women at random to do the research |
| B．The FDA doesn’t think phthalates have any risks |
| C．There are two types of phthalates that may affect childhood intelligence |
| D．The researchers are very confident about their conclusions |
What can you learn from the last but one paragraph?
| A．The evidence is not strong enough to change the policy |
| B．The policy should be stricter |
| C．A serious discussion is needed based on this study |
| D．All studies about childhood health should be involved |
This passage has probably been taken from _________.
| A．a children’s book |
| B．a science report |
| C．a nutrition guidebook |
| D．a health notice board |
【原创】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?
