A study of more than five million books, both fiction and non-fiction, has found a marked _ in the use of emotional words over time.The researchers form the University of Bristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise. They found that almost all of the categories showed a drop in these "mood words" over time.Only in the category of fear was there an increase in usage. "It is a steady and continuous decrease," said Dr Alberto Acerbi.He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape."One thing could be that in parallel to books the 20th century saw the start of other media.Maybe these media -- movies, radio, drama, had more emotional content than books." Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour:the ratio   between the two varied greatly, apparently mirroring historical events. During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash.But the ratio plunged at the height of the Second World War.Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends.In the paper, they even argue that the reverse could be true. "It has been suggested, for example, that it was the suppression   of desire in ordinary Elizabethan English life that increased demand for writing 'filled with romance and sex'... perhaps," they conclude, "songs and books may not reflect the real population any more than catwalk models reflect the average body." A study of more than five million books indicated a decrease in "mood words" over time except  _  . A) in the use of the words of historical events B) in the category of fear C) in the category of literature D) in the category of joy

My passion started decades ago as a kid on a flight to India. I was attracted by how such a large airplane was able to glide smoothly above the clouds. I made it a goal to become a pilot. I am now a pilot for American airlines. Though being a pilot consumes my life,it is a job worth doing. My job is slightly different compared to that of a typical pilot. Most pilots have their routes they fly. They then familiarize(...)themselves with the routes. However, in my case,I participate in any job where a pilot is immediately required. It is true that some days I might have a workday from nine in the morning to five in the afternoon. In fact,some days,I might even begin my work at three in the morning when I am needed to fly. Sometimes, as for the typical day,I do not have one. Having been on the job for over two decades,I have learned some important life lessons. As I greet passengers boarding the airplane,I realize I,along with other airline pilots, have enhanced the lives of those who we are serving. In fact, there is one particular experience that I will never forget. A family was walking in from the gate, explaining that their beloved one was ill and had to be taken to a big hospital in another city immediately. It was at this point that I realized just how important my job was. Therefore, my life as an airline pilot is definitely not for everyone. However,my job is something I enjoy thoroughly and will continue to do till I am old enough. As a pilot, I have been able to experience so many different types of situations in different places throughout the world. For anyone interested in piloting, I would recommend going for it. What is the main difference between the author's job and a typical pilot's? A) The author's working time is not regular. B) The author has his regular route he flies. C) The author has to get up very early every day. D) The daily working time of the author is longer.

Q: Six Chinese surveillance ships have entered waters near islands claimed by both China and Japan. China said the ships were carrying out "law enforcement" to demonstrate its jurisdiction over the islands, known as Diaoyu in China and Senkaku in Japan. At least two of the vessels left after the Japanese coast guard issued a warning, Japanese officials say. The move came after Japan sealed a deal to buy three of the islands from their private Japanese owner. Japan controls the uninhabited but resource-rich East China Sea islands, which are also claimed by Taiwan. The Japanese Coast Guard said the first two Chinese boats entered Japan's territorial waters at 06:18 local time (21:18 GMT Thursday), followed by another fleet of four other ships just after 07:00. The first two ships then left the area. A third ship left later on Friday morning, one report said. No force was used, Japanese officials added. "Our patrol vessels are currently telling them to leave our country's territorial waters," the coastguard said in a statement. The Chinese foreign ministry confirmed that its ships were there. "These law enforcement and patrol activities are aimed to demonstrate China's jurisdiction over the Diaoyu Islands and its affiliated islets and ensure the country's maritime interests," a statement said. The US has called for ''cooler heads to prevail'' as tension intensifies between China and Japan over the islands, which lie south of Okinawa and north of Taiwan. US Defense Secretary Leon Panetta is due to visit both Japan and China from this weekend as part of a tour of the region that also includes New Zealand.  The dispute has seriously marred diplomatic relations between China and Japan and threatens to damage the strong trading relationship, says the BBC's John Sudworth in Beijing. The row has also generated strong nationalist sentiment on both sides that observers say now makes it very difficult to be seen to be backing down, says our correspondent. The Japanese government says it is buying the islands to promote their... This news report is most likely to be selected from the   _  newspaper. A) British B) Chinese C) Japanese D) American
