Something in the air tonight
Since the 1940s, southern California has had a reputation for smog. Things are not as bad as they once were but, according to the American Lung Association, Los Angeles is still the worst city in the United States for levels of 26. pollutants. Gazing down on the city from the Getty Centre, an art museum in the Santa Monica Mountains, one would find the view of the Pacific Ocean blurred by the haze (霾). Nor is the state’s bad air 27. restricted to its south. Fresno, in the central valley, comes top of the list in America for year-round pollution. Residents’ hearts and lungs are affected as a 28. consequence.
All of which, combined with California’s reputation as the home of technological 29. innovation, makes the place ideal for developing and testing systems designed to monitor pollution in 30. detail. And that is just what Aclima, a new firm in San Francisco, has been doing over the past few months. It has been trying out monitoring that are 31. intended to yield minute-to-minute maps of 32. outdoor air pollution. Such stations will also be able to keep an eye on what is happening inside buildings, including offices.
To this end, Aclima has been 33. collaborating with Google’s Street View system. Davida Herzl, Aclima’s boss, says they have revealed pollution highs on days when San Francisco’s transit workers went on strike and the city’s 34. inhabitants were forced to use their cars. Conversely, “cycle to work” days have done their job by 35. creating pollution lows.

Questions 46 to 50 are based on the following passage.
Losing your ability to think and remember is pretty scary. We know the risk of dementia （癡呆） increases with age. But if you have memory slips， you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.
After age 50， it’s quite common to have trouble remembering the names of people， places and thing quickly， says Dr. Kirk Daffner of Brigham and Woman’s Hospital in Boston.
The brain ages just like the rest of the body. Certain parts shrink， especially areas in the brain that are important to learning， memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.
Forgetting the name of an actor in a favorite movie， for example， is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it， that’s far more concerning， Daffner says.
When you forget entire experiences， he says， that’s “a red flag that something more serious may be involved.” Forgetting how to operate a familiar object like a microwave oven， or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong.
But even then， Daffner says， people shouldn’t panic. There are many things that can cause confusion and memory loss， including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications like antidepressants.
You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory.And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive （認知的） reserve， Daffner says.
“Read books， go to movies， take on new hobbies or activities that force one to think in novel ways，” he says. In other words， keep your brain busy and working. And also get physically active， because exercise is a known brain booster.

A） Not all of them are symptoms of dementia.
B） They occur only among certain groups of people.
C） Not all of them are related to one’s age.

49. What should people do when signs of serious memory loss show up？
A） Check the brain’s cognitive reserve.
B） Turn to a professional for assistance.
C） Stop medications affecting memory.
D） Exercise to improve their well-being.
50. What is Dr Daffner’s advice for combating memory loss？

A letter written by Charles Darwin in 1875 has been returned to the Smithsonian Institution Archives（檔案館） by the FBI after being stolen twice.
“We realized in the mid-1970s that it was missing,” says Effie Kapsalis, head of the Smithsonian Institution Archives. “It was noted as missing and likely taken by an intern, from what the FBI is telling us. Word got out that it was missing when someone asked to see the letter for research purposes,” and the intern put the letter back. “The intern likely took the letter again once nobody was watching it.”
Decades passed. Finally the FBI received a tip that the stolen document was located very close to Washington, D.C. Their art crime team recovered the letter but were unable to press charges because the time of limitations had ended. The FBI worked closely with the Archives to determine that the letter was both authentic and definitely Smithsonian’s property.
The letter was written by Darwin to thank an American geologist, Dr. Ferdinand Vandeveer Hayden, for sending him copies of his research into the geology of the region that would become Yellowstone National Park.
The letter is in fairly good condition, in spite of being out of the care of trained museum staff for so long.“It was luckily in good shape,” says Kapsalis,“ and we just have to do some minor things in order to be able to unfold it. It has some glue on it that has colored it slightly, but nothing that will prevent us from using it. After it is repaired, we will take digital photos of it and that will be available online. One of our goals is to get items of high research value or interest to the public online.”
It would now be difficult for an intern, visitor or a thief to steal a document like this. “Archiving practices have changed greatly since the 1970s,”says Kapsalis. “and we keep our high value documents in a safe that I don’t even have access to.”
51.What happened to Darwin’s letter in the 1970s?
A. It was recovered by the FBI.
B. It was stolen more than once.
C. It was put in the archives for research purposes.
D. It was purchased by the Smithsonian Archives.
52. What did the FBI do after the recovery of the letter?
A. They proved its authenticity.
B. They kept it in a special safe.
C. They arrested the suspect immediately.
D. They pressed criminal charges in vain.
53.What is Darwin’s letter about?
A. The evolution of Yellowstone National Park.
B. His cooperation with an American geologist.
C. Some geological evidence supporting his theory.
D. His acknowledgement of help from a professional.
54. What will the Smithsonian Institution Archives do with the letter according to Kapsalis?
A. Reserve it for research purposes only.
B. Turn it into an object of high interest.
C. Keep it a permanent secret.
D. Make it available online.
55.What has the past half century witnessed according to Kapsalis?
A. Growing interest in rare art objects.
B. Radical changes in archiving practices.
C. Recovery of various missing documents.
D. Increases in the value of museum exhibits.

Passage One
Living in an urban area with green spaces has a long-lasting positive impact on people's mental well-being, a study has suggested. UK researchers found moving to a green space had a sustained positive effect, unlike pay rises or promotions, which only provided a short-term boost. Co-author Mathew White, from the European Centre for Environment and Human Health at the University of Exeter, UK, explained that the study showed people living in greener urban areas were displaying fewer signs of depression or anxiety. "There could be a number of reasons,” he said, “for example, people do many things to make themselves happier: they strive for promotion or pay rises, or they get married. But the trouble with all those things is that within six months to a year, people are back to their original baseline levels of well-being. So, these things are not sustainable; they don’t make us happy in the long term. We found that for some lottery（彩票）winners who had won more than £500,000 the positive effect was definitely there, but after six months to a year, they were back to the baseline."
Dr. White said his team wanted to see whether living in greener urban areas had a lasting positive effect on people's sense of well-being or whether the effect also disappeared after a period of time. To do this, the team used data from the British Household Panel Survey compiled by the University of Essex.
Explaining what the data revealed, he said: "What you see is that even after three years, mental health is still better, which is unlike many of the other things that we think will make us happy." He observed that people living in green spaces were less stressed, and less stressed people made more sensible decisions and communicated better.
46. According to one study, what do green spaces do to people?
A) Improve their work efficiency.
B) Add to their sustained happiness.
C) Help them build a positive attitude towards life.
D) Lessen their concerns about material well-being.
47. What does Dr. White say people usually do to make themselves happier?
A) Earn more money.
B) Gain fame and popularity.
C) Settle in an urban area.
D) Live in a green environment.
48. What does Dr. White try to find out about living in a greener urban area?
A) How it affects different people.
B) How strong its effect is.
C) How long its positive effect lasts.
D) How it benefits physically
49. What did Dr. White research reveal about people living in a green environment?
A) Their stress was more apparent than real.
B) Their decisions required less deliberation.
C) Their memories were greatly strengthened.
D) Their communication with others improved.
50. According to Dr. White, what should the government do to build more green spaces in cities?
A) Find financial support.
B) Improve urban planning.
C) Involve local residents in the effort.
D) Raise public awareness of the issue.
Passage Two
Questions 51 to 55 are based on the following passage.
You probably know about the Titanic, but it was actually just one of three state-of-the art(最先進的) ocean ships back in the day. The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company. The Olympic class included the Olympic, the Britannic and the Titanic. What you may not know is that the Titanic wasn’t even the flagship of this class. All in all, the Olympic class ships were marvels of sea engineering, but they seemed cursed to suffer disastrous fates.
The Olympic launched first in 1910, followed by the Titanic in 1911, and lastly the Britannic in 1914. The ships had nine decks, and White Star Line decided to focus on making them the most luxurious ships on the water.
Stretching 269.13 meters, the Olympic class ships were wonders of naval technology, and everyone thought that they would continue to be so for quite some time. However, all suffered terrible accidents on the open seas. The Olympic got wreaked before the Titanic did, but it was the only one to survive and maintain a successful career of 24 years. The Titanic was the first to sink after famously hitting a huge iceberg in 1912. Following this disaster, the Britannic hit a naval mine in 1916 and subsequently sank as well.
Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck. Most recognizable of the ship designs are the ship’s smoke stacks, but the fourth stack was actually just artistic in nature and served no functional purpose. While two of these ships sank, they were all designed with double hulls（船體） believed to make them “unsinkable”, perhaps a mistaken idea that led to the Titanic’s and the Britannic’s tragic end.
The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World War I. Eventually, she was taken out of service on 1935, ending the era of the luxurious Olympic class ocean liners.
51. What does the passage say about the three Olympic class ships?
A) They performed marvellously on the sea.
B) They could all break the ice in their way.
C) They all experienced terrible misfortunes.
D) They were models of modern engineering.
52. What did White Star Line have in mind when it purchased the three ships?
A) Their capacity of sailing across all waters.
B) The utmost comfort passengers could enjoy.
C) Their ability to survive disasters of any kind.
D) The long voyages they were able to undertake.
53. What is said about the fourth stack of the ships?
A) It was a mere piece of decoration.
B) It was the work of a famous artist.
C) It was designed to let out extra smoke.
D) It was easily identifiable from afar.
54. What might have led to the tragic end of theTitanic and the Britannic?
A) Their unscientific designs.
B) Their captains' misjudgment.
C) The assumption that they were built with the latest technology.
D) The belief that they could never sink with a double-layer body.
55. What happened to the ship Olympic in the end?
A) She was used to carry troops.
B) She was sunk in World War Ⅰ.
C) She was converted into a hospital ship.
D) She was retired after her naval service.

地鐵
近年來，中國有越來越多的城市開始建設地鐵。發展地鐵有助於減少城市的交通擁堵和空氣污染。地鐵具有安全、快捷和舒適的優點。越來越多的人選擇地鐵作爲每天上班或上學的主要交通工具。如今，在中國乘坐地鐵正變得越來越方便。在有些城市裏，乘客只需用卡或手機就可以乘坐地鐵。許多當地老年市民還可以乘坐地鐵。
In recent years, more and more cities in China begin to build the subway. Developing the subway helps to reduce traffic congestion and air pollution in cities. The subway has the advantages of being safe, fast and comfortable. More and more people choose the subway as the main means of transportation to work or school every day. Nowadays, it is becoming increasingly convenient to take the subway in China. In some cities, passengers can take the subway simply by using cards or mobile phones. Many local elderly people can also take the subway.
飛機
過去，乘飛機出行對大多數中國人來說是難以想象的。如今，隨着經濟的發展和生活水平的提高，越來越多的中國人包括許多農民和外出務工人員都能乘飛機出行。他們可以乘飛機到達所有大城市，還有很多城市也在籌建機場。航空服務不斷改進，而且經常會有廉價機票。近年來，節假日期間選擇乘飛機外出旅遊的人數在不斷增加。
In the past, traveling by plane was unimaginable to most Chinese people. Today, with the development of China’s economy and the improvement of its people’s living standards, an increasing number of Chinese people, including many farmers and migrant workers, can travel by air. They can fly to all major cities, and many cities are building airports. Air services continue to improve, and there are often cheap air tickets. In recent years, a growing number of Chinese people have chosen to travel by air during holidays.
公交車
公交車曾是中國人出行的主要交通工具。近年來，由於私家車數量不斷增多，城市的交通問題越來越嚴重。許多城市爲了鼓勵更多人乘坐公交車出行，一直在努力改善公交車的服務質量。車輛的設施不斷更新，車速也有了顯著提高。然而，公交車的票價卻依然相當低廉。現在，在大多數城市，許多當地老年市民都可以免費乘坐公交車。
Buses used to be the main means of transportation for the Chinese people. In recent years, traffic problems in cities are becoming increasingly severe due to the growing number of private cars. To encourage more people to take the bus, many cities have been making efforts to improve bus services. Bus facilities have been upgraded, and buses are now much faster.

任何時候，拿到寫作題目之後的第一件事，一定是審題，且應關注三個要素：體裁、話題、內容要求。本題要求寫的是“a short essay”，話題和內容要求是一個整體，即“the importance of reading ability and how to develop it” ，因此考生需要寫到兩點：一是閱讀能力的重要性；而是如何培養閱讀能力。
【思路】
首段：閱讀能力的重要性
二段：提升閱讀能力的方法
尾段：總結+號召
【範文】
Whether in history or in the present-day society, it is a common phenomenon for a host of people to regard reading ability as a vital quality in one’s work, life and study. Why? With excellent reading ability, one will find it easy to acquire knowledge from various books.
Then, how to cultivate one’s reading ability? I am convinced that there are at least two ways. Firstly, practice makes perfect. A typical example is me. During my first year in college, I had various difficulties or troubles in understanding either English or Chinese reading materials. Fortunately, my teacher told me “Knowledge is a treasure, but practice is the key to it.” It was through constant practice that I improved my ability to read. Secondly, based on a survey, a majority of successful learners acknowledge that they prefer writing reviews after reading. They deem that writing reviews brings them systematic knowledge, arouses their enthusiasm for further reading and helps them enhance their reading ability.
We, as college students, should bear in mind that knowledge originates from reading. Thus, I believe that if we try our utmost to practice reading and write reviews after reading every day, we are likely to be knowledgeable persons.
【參考譯文】
無論是在歷史上還是在當今社會，很多人普遍把閱讀能力當做工作、生活和學習中的一項重要素質。爲什麼？有了出色的閱讀能力，人們會發現很容易從各種圖書中獲取知識。
那麼，如何培養閱讀能力哪？我相信至少有兩種途徑。首先，熟能生巧。一個典型例子就是我自己。在大學的第一年，無論是在理解漢語閱讀材料還是英文閱讀材料方面，我都有不少麻煩或困難。幸運的是，我的老師告訴我“孰能生巧”。正是通過不斷訓練我提升自己閱讀能力。第二，根據一項調查，絕大部分成功的學習者都承認他們閱讀之後喜歡寫書評。他們認爲寫書評帶給他們系統的知識，喚起他們進一步閱讀的熱情，幫助他們提升閱讀能力。
作爲大學生，我們應該牢記的是知識源自閱讀。因此，我相信如果盡最大努力每天堅持閱讀實踐並在讀後寫書評，我們就可能成爲知識淵博的人。
