1 . We often hear friends ask why they should read fiction. There is so much to learn from history, from what is going on at the frontiers of science, and from contemporary studies of human behavior. Why should they spend their scarce "free time" reading fiction, the purpose of which, at best, is only entertainment?
We are disappointed about such comments. Yes, we respond, we do find pleasure in reading fiction. But we also learn much about how to best live our lives in ways that can only be captured by fiction. We recognize that some novels are entertaining, but leave no lasting impression. What makes a novel more than entertainment?
Our answer is that we don't just read great books - they read us as well. The human condition is complex and contradictory, layered like an ice-cream dessert, with flavors mixed among the layers. A great novel reflects that complexity. We may read it several times, as we do with our favorites, and each time it is like finding an old friend and gaining new insights from that friend. We put it down with new understandings of the world around us and, most important, of ourselves.
Let's look at the novel Frankenstein, written in 1818 by Mary Shelley. Frankenstein is not the monster, but a young man seeking out the secrets of the universe. He collects body parts and charges it with life. When the dull yellow eyes open, however, Frankenstein, shocked by what he has done, abandons the creature, which ultimately kills Frankenstein's brother, his bride, and his best friend.
On one level, Frankenstein is entertaining - a good horror story, though a little dated. But Shelley writes more than just that. On a deeper level, her book forces us to ask whether humans reach too far to gain knowledge that is as forbidden as the fruit of the Garden of Eden. This theme, as old as the legend of Prometheus （普罗米修斯），dominates Frankenstein. Shelley, of course, knew nothing of genetic （遗传的）engineering that happens today. She was deeply troubled by what human beings might discover about themselves, and the effects of those discoveries on society. Our reading of great literature can also be enriched by understanding the author's personal interests and anxieties.

3 . Israeli researchers say they have created the world's first three-dimensional, or 3D-printed heart using a patient's own cells. They described the experiment as "a major medical breakthrough." Tal Dvir, the lead researcher on the project, said in a statement that it was the first time that human cells had been used with 3D printing technology to successfully create a whole heart. Dvir added that the "printed" heart contains blood vessels which are needed to pump blood. The development marks a step forward for 3D printing in the medical field.
The researchers took samples of fatty tissue from patients. This material was then used to develop “ink” for the 3D printing process. First, the researchers created patches of tissue from the patient’s own cells. Later, they used that same process to create a small version of a whole heart. Using the patient’s own cells is important to reduce the risk that the body’s system to fight infection will reject a transplanted organ.
The goal, the researchers said, is to treat heart disease. The World Health Organization reports that heart disease is by far the leading cause of death worldwide. For patients with severe heart disease, a heart transplant is currently the main treatment available. The researchers hope their invention can help ease the demand for heart transplant donors.
Dvir says that the newly-created heart represents great progress. However, more research and development is needed to produce a fully operating, transplantable organ. One of the biggest challenges for the engineering team will be finding a way to create a human-sized heart.
Dvir said his team planned to transplant heart models designed for animals, possibly within the next year. He added that, for human use, “simpler organs” will likely be produced before hearts. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world,” Dvir said. He hopes such methods will be used “routinely” to produce organs in the future.

4 . While flatmates can bring about stress and difficulty, they can also be great company and develop into wonderful, lifelong friends. Before making the decision to live with a flatmate or to live alone, consider carefully all the accompanying advantages and disadvantages.
Most people join forces with a flatmate primarily due to financial problem. A shared living space also means you're responsible for only half of the rent or shared bills. Additionally, when you're splitting costs, you can afford a better apartment than you could alone. However, money can become a point of argument for flatmates as well. If your flatmate gets laid off or quits his job, you may have to pick up his bill until he's back on his feet. Your flatmate may also insist he owe less because he doesn't use the shower too often.
In addition to bills and the rent, flatmates also typically share responsibility for unpleasant tasks, such as cleaning or doing the dishes. Without a flatmate, cleaning and tidying responsibilities are yours alone. However, flatmates also frequently end up sharing plenty of other things many people would rather not: use of the TV, the bathroom, food and even clothing, for example. You may have to wake up earlier than you'd like to get a hot shower before work or give up watching your favorite show because your flatmate beat you to it.
When you live alone, you get to determine the terms of your social life, and you go home to an empty house or apartment at the end of the day. That can be preferable if you're a serious student or professional, someone who needs to work and rest in the quiet of an apartment. With a flatmate, there are unexpected guests and your social options can expand sharply. Keep in mind, however, that having a flatmate means that he may feel social when you do not, and you may have to deal with wanted house guests.
1. What's the main reason for most people to share a flat?| A．Ensuring safety. | B．Saving money. |
| C．Sharing housework. | D．Reducing loneliness. |
| A．He likes a peaceful life. |
| B．He has excellent social manners. |
| C．He keeps everything in the room tidy. |
| D．He often turns away unexpected guests. |
| A．By describing the process. | B．By stating an argument. |
| C．By making comparisons. | D．By analyzing the outcome. |

5 . With the infection being brought under control, more and more galleries and museums are reopening. While many museums have been putting exhibitions online, visitors still prefer to enjoy works of art in person. Here are four major art exhibitions that are held offline.
The Palace Museum (Dec. 10—Feb. 15)
The exhibition, Everlasting Splendor which is being held in the Meridian Gate Galleries, marks the 600th anniversary of China’s imperial palace. Over 400 cultural relics are displayed at the exhibition, reflecting the history of the Forbidden City’s construction, the development of its layout, and how it has been protected and restored in the past decades.
The National Museum of China (Jan. 4—Mar. 29)
The exhibition, A Sail Over Miles, offers a brief review of the ancient Silk Road in ceramics (陶瓷). It guides visitors through the manufacturing, export and shipping routes from the Tang Dynasty to the Qing Dynasty with over 300 ceramic relies, including a pot dug from Nanhai No 1, a Chinese cargo ship dating back more than 800 years. The exhibition also shows Japanese, Korean and British ceramics, reflecting the influence of China’s porcelain-making techniques in local industries.
The Capital Museum (Jan. 1—Mar. 30)
The Capital Museum is to host Man of Infinite Refinement: Special Exhibition on the Paintings and Calligraphy of Su Shi, a calligraphy and painting exhibition on the legacy of Su Shi, an iconic figure of ancient Chinese literature and fine arts. The 78 exhibits on display spans from the Northern Song Dynasty through recent history and cover a range of media, including calligraphy, paintings, documents and rarely seen books.
The National Art Museum of China (Nov. 30—Feb. 10)
On show are nearly 300 objects, including paintings, calligraphy works, carved seals, manuscripts, letters and books. Donation of Rong Geng not only reflects his academic accumulation over the years, but forms the basis for his becoming such a well-rounded scholar in the area of Chinese cultural traditions.
Rong Geng (1894—1983), a scholar of Chinese paleography, educator and connoisseur of antiquities, is little known to the general public. However, his extensive studies of ancient Chinese writings and his former collection of archaic oracle bones and bronzes continue to enrich people’s cultural life. In his lifetime, Rong donated to the State nearly 200 bronze objects, all of which are now housed at numerous public museums and universities.

6 . When whales die and sink to the ocean floor, their bodies -known as whale falls -provide rich nutrients for other creatures of the deep.
Chinese scientists found a whale fall in the South China Sea during a recent scientific research voyage. It was the first time that Chinese researchers had run across this rare type of ecosystem. It was an important finding, showing China's progress in deep-sea exploration technology, Xie said, a professor at Sun Yat-sen University.
During the 22-day deep-sea exploration from March 10 to April 2. 60 scientists conducted 22 dives and successfully completed a number of scientific tasks. The research aimed to gather information about the key processes of typical seamount ecosystems in the Western Pacific: Ocean. The whale fall was found in a seamount 1,600 meters deep in the central South China Sea. Though the whale fall was only about 3 meters long, it was of great importance in understanding the sea ecosystems, Xie said.
There were dozens of white armored shrimp, red shrimp and several eels found near the whale fall. The eels were eating the tail muscles of the whale fall. This shows that the whale died not long ago and that the whale fall was still in the first stage of decomposition and thus had rare value for long-term observation, Xie said.
Like cold springs, whale falls are homes for creatures of the deep. In the northern Pacific Ocean, they have supported the survival of at least 12,490 kinds of organisms—classed in 43 species—and promote prosperity far beneath the surface, according to data from the university.

7 . A new study on the link between chili and dementia(老年痴呆) may bring bad news for spicy food addicts. Researchers have found that eating lots of chili may cause an increased risk of dementia.
The study, led by Zumin Shi, analyzed 4,582 Chinese adults aged 55 and above between 1991 and 2006 and found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. “Chili consumption was found to be beneficial to body weight and blood pressure in our previous studies. However, in this study, we found negative effects on cognition among older adults,” Shi said in a press release published Tuesday.
“Chili is one of the most commonly used spices in the world and particularly popular in Asia compared to European countries,” Ming Li from the University of Southern Australia said in the press release. “In certain regions of China, such as Sichuan and Hunan, almost one in three adults consumes spicy food every day.”
The researchers said people of normal body weight may be more sensitive to chili intake and hence their memory and weight suffer a bigger impact. Worldwide, around 50 million people have dementia, and Alzheimer’s disease is the most common form that may contribute to 60 percent to 70 percent of the cases, according to the World Health Organization. At present, no treatment can cure dementia or change its progressive course.

8 . Sharks are amazing creatures. They are known as the deadliest hunters in the sea. Fortunately most are not, but there are some kinds of sharks that can be extremely dangerous. Look at these short descriptions of four kinds of sharks.
The Great White Shark
Great Whites are one of the most frightening creatures in the sea. They live in tropical and subtropical waters, and they can grow up to 9 meters long. Most Great Whites are actually grey, blue or brown with a white belly, and their powerful teeth are triangles with edges like saws.
The Whale Shark
Whale Sharks are the largest kind of shark in the world-up to 11 meters in length. They live in tropical waters all around the world, but they are not dangerous. Whale Sharks are brown or grey with white or yellow stripes. They often travel near the surface of the sea.
The Mako Shark
Mako Sharks are fierce predators. They come from the same family of sharks as the Great White and they are especially fast-they can swim at speeds of up to 65 kilometers per hour. They are large bluish sharks found in the Atlantic, Pacific and Indian oceans. Mako Sharks can grow up to 3 meters long.
The Great Hammerhead Shark
The Great Hammerheads' most striking feature is its wide thick head which looks like a hammer. The average size of a Great Hammerhead is approximately 3.5 meters, but can grow up to 6 meters long. These sharks average over 500 pounds but can weigh as much as 1,000 pounds. Like most sharks the females are larger than the males. They have several rows of teeth that have 24 to 37 teeth per row. The Great Hammerhead has a very keen sense of smell, which helps find its prey.
1. What can we learn from the text?| A．Sharks usually live in icy waters. |
| B．Mako Sharks are fast but not dangerous. |
| C．Great Whites have at least 24 to 37 sharp teeth. |
| D．Whale Sharks are bigger than other sharks in the sea. |
| A．The size of its body. | B．The waters it lives in. |

9 . Vaccines(疫苗) may soon make their first film appearance. Led by expert Maria A. Croyle, researchers have developed a thin sheet that preserves vaccines for long periods without refrigeration. This means the carefully cooled small bottles now used to ship vaccines could potentially be replaced by lightweight films that can be mailed in an envelope and stored on a shelf.
Croyle’s laboratory began developing the technology in 2007. Inspired by amber’s ability to preserve the DNA of insects, the researchers set out to create their own version of the substance by mixing “a lot of sugar and a little bit of salt, much like hard candy,” Croyle explains. The vaccine-containing film is administered by mouth—sweet news for many who dislike needles.
The film is tailored to suit each specific vaccine candidate and provide a protective coating. “We’ve learned over time that the key to really stabilizing whatever the film holds is to have it intermixed with all the components,” Croyle says, adding that the process is quick and uses affordable, standard equipment. “We really wanted to come up with something that would be transferable to developing countries.”
Immunization(免疫) programs depend heavily on keeping vaccines cold(2℃-8℃) as they are transported, sometimes over thousands of kilometers to far-away locations. Delivery can be difficult and costly, and transport disruptions can cause the vaccines to be ineffective.
But this new product can store live viruses, bacteria and antibodies for several months at 20℃. In a paper published in Science Advances, the scientists show that the live viruses in one vaccine were preserved in the film even after 36 months. They also find that a flu vaccine suspended in their film compares favourably with a traditional flu shot(流感预防针). “The study demonstrates early proof of concept for an exciting platform for vaccine product development,” says Lisa Rohan, a pharmacologist, who was not involved in the study. She also notes that each vaccine type would need a custom formulation(配方) for future stages of development.
Finding partners to mass-produce for clinical trials is the researchers’ most pressing problem, Croyle says. They are also exploring packaging methods to keep their films stable up to 40℃.
Size is a major advantage—a letter-sized sheet of the film can carry more than 500 doses(剂) of vaccine, about 1⁄900 the weight of the same amount of traditional doses. By making it easier and cheaper to ship and preserve vaccines efficiently, Croyle says, the technology could vastly improve immunization rates the world over, particularly in middle- to low- income countries.

10 . Remember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be more salutary to your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.
Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds that provide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more effectively than fluoride.
Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), and protects against tooth decay.
Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.
1. The word “salutary” in paragraph 1 means?| A．Beneficial. | B．Harmful. | C．Familiar. | D．Useless. |
| A．It can help chocolate cure tooth decay. |
| B．It can effectively stop teeth from decaying. |
| C．It may protect teeth better than toothpastes do. |
