A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate. The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1 ,000 taxis per month. They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year. Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million. “We are eager to continue to validate (证实）the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors” explained Prof Ho. 21. What do Prof Ho’s words in the last paragraph suggest? A. School buses should be painted yellow. B. Their study will be furthered. C. Their findings are worth popularizing. D. Yellow should be widely used in public transport. 22. What’ s Prof Ho’s study based on? A. Physical risks taxi passengers experience. B. The economic effect of changing taxi color. C. Personal reports from taxi drivers worldwide. D. Data from Singapore’s largest taxi company. 23. Why do yellow taxis result in fewer accidents? A. Because yellow signals a warning of danger. B. Because yellow can be seen more easily. C. Because drivers tend to he more careful in yellow taxis. D. Because people act more quickly in yellow surroundings. 24.What can be the best title for the text? A. Safer to Ride in Yellow Taxis. B. Caution: Yellow Taxis ahead. C. Why Are Yellow Taxis Preferred? D. How Can Colors Help Prevent Accidents? |

B vitamins（维生素）may offer some protection against the effect of air pollution, a new study suggests. The scientists say the effect is real but stress the limitations of their work. Follow-up studies are urgently needed, they say, in heavily polluted cities like Mexico. According to the World Health Organization (WHO), over 90% of the world’s population live in heavily-polluted areas. One of the pollutants that is considered the most dangerous is particulate matter, referred to as PM2.5. At around 1/30 the width of a human hair, PM2.5 can go deep into the human lung and contribute to lung and heart health problems in the young and old. Scientists have long suspected that PM2.5 causes what are termed epigenetic（表观遗传）changes in our cells that can damage our health. Now in this new human trial, an international team of scientists wanted to see if exposure to concentrations of PM2.5 could be mitigated by daily B vitamins. Ten volunteers were tested initially exposed to clean air and their basic responses were measured. The same volunteers were later tested with large doses（剂量）of B vitamins while exposed to air containing high levels of PM2.5. The researchers found that a four-week B vitamin intake limited the PM2.5 effect by between 28-76% at ten gene locations. They found a similar reduction in effect on the mitochondrial DNA, the parts of cells that produce energy. However, the researchers caution that their study, while observing a real effect, has limitations. As well as the small number of participants, there was little information on the size of the B vitamin dose that caused the response. 25. What is the main idea of the text? A. Exposure to PM2.5 is more and more serious. B. PM2.5 can lead to epigenetic changes. C. Further studies should be done on PM2.5. D. B vitamins may fight against PM2.5. 26. How many limitations does the text mention about the new study? A. 2. B. 3. C. 4. D. 5. 27. Which can replace the underlined word "mitigated" in Paragraph 4? A. measured B. ignored C. reduced D. observed 28. How does the writer of the text like the new study? A. He believes it deeply. B. He criticizes it strongly. C. He thinks it needs testing again. D. He shows no opinion about it. |

In James Cameron’s fantasy films, such as Avatar and The Abyss, the unexplored is decorated in color and filled with alien danger. But on his dive to the deepest place on Earth, which took place on a Sunday last month, reality proved far different: white, deserted, and dull. “I felt like I literally had gone to another planet and come back,” Cameron said after returning from the cold, dark place in the western Pacific Ocean, nearly 7 miles (11km) below the surface. “It was a very fantastic day.” Cameron is the first person to explore the deepest valley in the ocean since two men made a 20-minute trip there in 1960. He spent about three hours gliding (滑行) through the icy darkness, brightened only by lights on the one-man sub (潜水艇). This deepest section of the Mariana Trench is so untouched that at first it appeared dull. But there’s something strangely interesting about the first pieces of video that Cameron shot — a sense of aloneness. “It’s really the sense of isolation (孤立，隔离), realizing how tiny you are down in this big, black and unexplored place,” the Titanic director said. The wordless minute-long video, released by sponsor National Geographic, shows Cameron’s sub gliding across what he calls “the very soft, almost gelatinous (胶状的) flat plain.” To Cameron, the main thing was to appreciate being there. “There had to be a moment where I just stopped, and took it in, and said, ‘This is where I am; I’m at the bottom of the ocean, the deepest place on Earth. What does that mean?’” Cameron told reporters during a conference call. The trip was only about half as long as planned because Cameron’s battery ran low. He said he would return and film it in 3D for later viewing. “I see this as the beginning,” Cameron said. “It’s not a one-time deal and then moving on. This is the beginning of opening up this new frontier.” 29. Why did Cameron dive to the deepest place on Earth? A. To study ocean creatures in the deepest valley. B. To prove his strong will and perseverance. C. To get support from National Geographic. D. To open up a new frontier. 30. Which of the following statements is TRUE according to the passage? A. Cameron’s fantasy film, Avatar was inspired by his dive to the deepest place on Earth. B. Cameron glided through the icy darkness alone by lights of the one-man sub. C. Cameron didn’t stay at the bottom of the ocean as planned because he was worn out. D. Cameron felt bored when he went to the deepest valley in the ocean. 31. The underlined sentence in the passage means that ______. A. he appreciated and took pride in being at the bottom of the ocean B. he was disappointed because the trip was only about half as long as planned C. Cameron wanted to show the public he had been to the deepest place on Earth D. he wouldn’t stop exploring the deepest place in the future 32. According to the passage, which of the following words best describes Cameron? A. Generous. B. Diligent. C. Self-centered. D. Adventurous. |

When one hitchhikes — travelling by getting lifts from passing vehicles without paying, one 41 long hours either waiting at a likely intersection (岔路口) or 42 heavily down the road, and when I was so engaged, I found 43 in singing songs or in reciting the many poems I had memorized, or 44 the latest postcards I had added to my art collection. I was in many ways the 45 boy on the road, in other ways the richest, and I was always happy to be on the road meeting new people, hearing new stories and seeing new 46 . I have 47 been clever enough to analyze （分析） the motivation or drive for my hitchhiking, but I doubt that it was related to any 48 weakness. I have never been out of mind. Home was not exciting enough to keep me 49 to it.

When I was 52 , hiking with very little money and a thousand miles from home, I was convinced （相信）that I would 53 my journey safely, for I was quite optimistic as a boy then with 54 life before me. So it was with me when I was at sixty — I was still optimistic with so many 55 before me. It seems that I was born to 56 at the world, and such men do not write tragedies. (悲剧) The simple fact seems that whenever I saw that 57 road outside my house, I was 58 to explore what it was like. What Walt Whitman once said would always push me to go on : “Afoot and light-hearted I take to（走向）the open 59 , healthy, free, the world before me, the long brown path before me leading wherever I 60 .” That makes a difference to my life. 41.
