4. Passage Twenty-ThreeWashington Irving was America’s first man of letters to be known internationally.His works were received enthusiastically both in England and in the United States.He was， in fact， one of the most successful writers of his time in the country， and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States.The respect in which he was held was partly owing to the man himself， with his warm friendliness， his good sense， his urbanity， his gay spirits， his artistic integrity， his love of both the Old World and the New.Thackery described Irving as “a gentleman， who， though himself born in no very high sphere， was most finished， polished， witty; socially the equal of the most refined Europeans.” In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young， uncultured nation—and he received the medal of the Royal Society of Literature.America made him ambassador to Spain.Irving’s background provides little to explain his literary achievements.A gifted but delicate child， he had little schooling.He studied law， but without zeal， and never did practice seriously.He was immune to his strict Presbyterian home environment， frequenting both social gatherings and the theatre.Which of the following best describes the effect of Irving’s personal qualities on his literary success?

2. Passage Thirty-TwoHave you ever heard of a pawpaw (木瓜)? If not， do not feel bad.Many Americans do not know of the fruit， although it is native to the U.S.Once， however， it was one of the most popular fruits in North America.Happily， those who love the pawpaw are trying to return it to its former position in American foods.A pawpaw is a tropical fruit that used to be grown along the East Coast from New York to Florida and all over the eastern U.S.At one time， it could be found as far west as Nebraska.The pawpaw was an important food for Native Americans and even early European settlers.Pawpaws reportedly were a favorite treat of George Washington， the first U.S.president， who especially liked them cold.Thomas Jefferson， the third U.S.president， was also a fan of the fruit.He planted pawpaws at his home in Virginia.He also sent pawpaw seeds to his friends in France.American explorers Lewis and Clark wrote in their journals about the pawpaw.The pawpaw is difficult to be sold commercially.The fruit requires a very special environment—low， wet areas that sometimes flood.It has a very short harvest season， from two to three weeks in September and October.In addition， the fruit is good to eat for only two to three days after harvesting.This makes it hard to sell anywhere distant from the pawpaw tree it comes from.Planters are again growing pawpaw trees and harvesting the fruit.In several states farmers have organized “pawpaw festivals” to reintroduce people to food.At such a festival in Maryland recently， farmers displayed different products made with pawpaws， like pawpaw jams， pies， ice-cream and beer.The pawpaw used to be found mainly ().

5. Passage TenNowadays， children heavily cling to digital devices such as computers and smart phones.Some spend up to six hours a day on their digital devices.They can be playing games online with people elsewhere， updating their status on social media， texting friends， or looking for the latest apps to download to their computers or smart phones.This worried Martin Strott.He is the headmaster of the Old Hall School in Wellington， England.He was so concerned that he challenged his students to take part in a week of (“digital detox”)， a program to reduce their reliance on digital devices.Mr.Strott told the local newspaper， the Shropshire Star， that too much screen time would affect the development of their social skills.At another interview with a magazine， he mentioned that this over-reliance on digital devices “takes away family time and reduces their chances of face-to-face communication”.The parents are happy with the program.But what about the children? Nine-year-old Fred usually spends around two hours on his digital devices at home after school and around 12 hours on weekends.For him， the digital detox experience was “really hard”.He said that he had been engaged in many interesting outdoor activities organized by the headmaster， but still missed his phone and online games.The idea of keeping children away from their digital devices for a while to prevent too much dependence on them is not particularly new.There have been similar practices in the United States.But are they effective in the long run? According to Mr.Strott， even if kids go back to their digital devices， the hope is that at least they will think about how they will use their time.What is the passage mainly about?

1. Passage Thirty-OneAdam Smith was the first person to see the importance of the division of labor.He gave us an example of the process by which pins were made in England.“One man draws out the wire， another strengthens it， a third cuts it， a fourth points it， and a fifth gives it a head.Just to make the head requires two or three different operations.The work of making pins is divided into about eighteen different operations， which in some factories are all performed by different people， though in others the same man will sometimes perform two or three of them.”Ten men， Smith said， in this way， turned out twelve pounds of pins a day or about 4，800 pins a worker.But if all of them had worked separately and independently without division of labor， they certainly could not have made twenty pins in a day and not even one.There can be no doubt that division of labor is an efficient way of organizing work.Fewer people can make more pins.Adam Smith saw this， but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still.But division of labor adds nothing new， it only enables people to produce more of what they already have.According to the passage， Adam Smith was the first person to ().

37. Questions 36 to 40 are based on the following passage.Recognizing when a friend or colleague feels sad， angry or surprised is key to getting along with others.But a new study suggests that being sensitive to people’s feelings may sometimes come with an extra dose of stress.This and other research challenge the prevailing view that emotional intelligence is uniformly beneficial to its bearer.In a study， Psychologist Myriam Bechtoldt of the Frankfurt School of Finance and Management in Germany asked 166 male university students a series of question to measure their emotional intelligence.For example， they showed the students photographs of people’s faces and ask them to what extent feelings such as happiness or disgust were being expressed.The students then had to give job talks in front of judges who displayed serious facial expressions.The scientists measured concentrations of stress hormones in the students’ saliva (唾液)before and after the talk.In students who were rated more emotionally intelligent， the stress measures increased more during the experiment and took longer to go back to baseline.The findings suggest that some people may be too emotionally clever for their own good， says Bechtoldt.“Sometimes you can be so good at something that it causes trouble，” she notes.Indeed， the study adds to previous research hinting at a dark side of emotional intelligence.A study published in 2002 in Personality and Individual Differences suggested that emotionally perceptive people might be particularly influenced by feelings of depression and hopelessness.Furthermore， several studies have implied that emotional intelligence can be used to manipulate others for personal gains.
More research is needed to see how exactly the relation between emotional intelligence and stress would play out in women and in people of different ages and education levels.Nevertheless， emotional intelligence is a useful skill to have， as long as you learn to also properly cope with emotions—both others’ and your own， says Bechtoldt.For example， some sensitive individuals may assume responsibility for other people’s sadness or anger， which ultimately stresses them out.Remember， as Bechtoldt says， “you are not responsible for how other people feel.”What was the purpose of psychologist Myriam Bechtoldt’s experiment?

A. 　To define different types of human feelings.

B. 　To assess the impacts of being emotionally clever.

C. 　To demonstrate how to distinguish different feelings.

D. 　To identify gender differences in emotional intelligence.
