The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which heis capable. The importance of environment in determining an individual’s intelligence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark’ s IQ was 125 , twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.31．This selection can best be titled______.A．Measuring Your IntelligenceB．Intelligence and EnvironmentC．The Case of Peter and MarkD．How theBrain Influences Intelligence正确答案：B32．The best statement of the main idea of this passage is that______.A．human brains differ considerablyB．the brain a person is born with is important in determining his intelligence C．environment is crucial in determining a person’ s intelligenceD．persons having identical brains will have roughly the same intelligence正确答案：C33．According to the passage, the average IQ is______.A．85B．100C．110D．125正确答案：B34．The case history of the twins appears to support the conclusion that______.A．individual with identical brains seldom test at same levelB．an individual’s intelligence is determined only by his environmentC．lack of opportunity blocks the growth of intelligenceD．changes of environment produce changes in the structure of the brain正确答案：C35．This passage suggests that an individual’ s IQ______.A．can be predicted at birthB．stays the same throughout his lifeC．can be increased by educationD．is determined by his childhood正确答案：CSelling Expertise on the Internet for Extra Cash Teresa Estes, a licensed mental-health counselor, watched as business at her private practice decreased last year. Then the single mother turned to her keyboard to boost her income. Ms. Estes applied to become an “expert” on Live Person Inc., a Web site where clients pay for online chat time with professionals and advisers of all fields. For $ 1.89 a minute —a rate she set —the 39-year-old from Marianna, Fla., dispenses advice to clients around the globe. She spends about four hours a day online, often at night, when her daughter has gone to bed. “It was the economy,” she says of her move to take her skills online. “Live Person is more profitable than my private practice.” Ms. Estes had charged her private clients up to $ 75 an hour. As the recession(经济衰退)deepens, a small but growing number of people are taking their skills online, offering expertise or performing specified tasks for a fee. Labor-at-the-keyboard sites are gaining popularity as people increasingly turn to the Web in search of work. Internet job-search sites saw a 51% rise in traffic from January 2008 to January 2009, according to comscore Media Metrix, to 26.7 million unique visitors. Among the many fee-for-service Web sites out there, at least three are attracting a significant number of users —though consumers should exercise a healthy degree of skepticism(怀疑态度)when consulting any of these sites. Live Person seeks out experts on a slew of topics, including mental health, financial services, shopping and fashion, as well as psychics and spiritual advisers. Mechanical Turk, a Web service run by Inc., pays workers to perform tasks, such as cataloging products online. Associated Content pays contributors to write articles on a wide range of subjects, from organic flower gardening to how to apply for financial aid. Live Person went public in 2001, and the current version of the site was launched in late 2007. Today, the site has 30,000 registered experts, attracting an average of 100,000 people a year who pay for the offered services, says Chief Executive Officer Robert Locascio. Roughly 3,500 people have made contributing to the site their full-time job, he says. Associated Content reviews submissions in house and then decides how much to pay for them. The site, which specializes in how-to pieces and feature stories on news topics, had 237, 000 registered contributors and more than one million content pieces as of February, both about double from the same month a year ago. Sabah Karimi, a 26-year-old fromOrlando, Fla., left a career in marketing to become a full-time freelance writer and now spends between 8 and 10 hours a week writing forAssociated Content. She has been at it for about three years and says she earns roughly $ 1,000 a month from her past and current submissions. Mechanical Turk is based on “crowd sourcing” , or breaking a task into lots of tiny pieces and giving it to a big group of people to complete quickly. Most of these jobs —which the site calls HITs, for human intelligence tasks —pay just a few cents. Efficient Mturkers, as they call themselves, can make more than $ 100 a week doing things such as finding someone ‘s email address or labeling images of a particular animal in a photograph.36．What is the passage mainly talking about?A．The economic recession will last a few years.B．More people are taking their skills online to make money.C．Asking for advice through the Internet is a good way to solve your problems.D．People shouldn’t release their financial and personal details online.正确答案：B37．Live Person Inc. is a website where .A．people chat with each other and make friends freelyB．professionals and advisers help others for freeC．people pay money for applying to become an expertD．clients pay for online chat time with professionals and advisers正确答案：D38．Why are labor-at-the-keyboard sites gaining popularity?A．Because people love to work on the Internet.B．Because more people are finding jobs on the Internet.C．Because working on the Internet is easier than other ways of working.D．Because people are being asked to work on the Internet.正确答案：B39．What is Sabah Karimi’ s job?A．She is a part-time freelance writer.B．She is a news writer.C．She submits articles to Associated Content.D．She reviews articles for Associated Content.正确答案：C40．Mechanical Turk originated as a method to______.A．label images of a particular animal in a photographB．serve a variety of companies who need Web tasks performedC．help Amazon manage its product databaseD．find someone’ s email address正确答案：BThe greatest contribution to civilization in the century may well be the air-conditioning- and American leads just as amazing is the speed with which this situation came to be. Air-conditioning began to spread in industries as a production aid during World War II. Today most Americans need to take air-conditioning for granted to homes, offices, factories, theatres, shops, studios, schools, hotels, and restaurants. But not everybody is aware that high cost and easy comfort are merely two of the effects of the vast cooling of American. In fact, air conditioning has substantially altered the country’s character and customs. Many of the byproducts are so conspicuous that they are scarcely noticed. To begin with, air-conditioning transformed the face of America by making possible those glassy, boxy, sealed-in skyscrapers. It has been indispensable, no less, to the functioning of sensitive advanced computers, whose high operating temperatures require that they be constantly cooled. It has, at will, forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life. It is really surprising that the public ‘s often noted withdrawal into self-pursuit and privacy has coincided with the historic spread of air-conditioning. Though science has little studied how habitual air-conditioning affects mind and body, some medical experts suggest that, like other technical avoidance of natural variations in climate, air-conditioning may damage the human capacity to adapt to stress. If so, air-conditioning is only like many other greatly useful technical developments that liberate man from nature by increasing his productivity and power in some way - while indirectly weakening him in others.41．According to this selection, which of the following constitutes the unique character ofU.S.?A．Its excessive use of air-conditioning.B．Its advanced computerized civilization.C．Its public’ s retreating into self-pursuit.D．Its greatest contribution to human civilization.正确答案：A42．According to the author, the chief consequence brought about by the wide application of air-conditioning is______.A．the loss of human capacity to adapt to changes in climateB．the reduction of social communications of neighborhood lifeC．the active life style of all its usersD．the decreased human production and power正确答案：B43．The tone of this selection reveals that air-conditioning______.A．has little effect on its usersB．has more effect on body than on mindC．brings more benefits than damage to its usersD．does harm as well as good to its users正确答案：C44．Who benefits the least from air-conditioning according to the author?A．Medical experts.B．Manufacturers.C．Factory laborers.D．Consumers.正确答案：D45．What is the author’ s overall attitude towards air-conditioning?A．NeutralB．ObjectiveC．CriticalD．Compromising正确答案：CIn the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. equal. Some of them decided to “drop out” of American society and form their own societies. They formed Utopian communities , which they called “ communes,” where they could follow their philosophy of “do your own thing.” A group of artists founded a commune in southern Colorado called “Drop City.” Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey’s Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old schoolbuses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin’s followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the group were arrested for growing marijuana. Not all communes believed in the philosophy of “ do you own thing,” however . Twin Oaks , a commune founded inVirginia in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefullycontrolled by Skinner’s “conditioning” techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a Utopian city Arizsona where 2500 people will live closely together in one large building called an “archology” Soleri believes that people must live closely together so that they will all become one.46．Why did some young Americans decide to “drop out” of society during the 1960s?A．They were not satisfied with American society.B．They wanted to grow marijuana.C．They wanted to go to the Vietnam War.D．They did not want all people to be equal.正确答案：A47．Where did the members of the Hog Farm commune live?A．In dome-shaped houseB．In old school busesC．On a farm in TennesseeD．In an archology in Arizona正确答案：B48．Who gave the people of Drop City the idea to build dome-shaped house?A．Paolo SoleriB．B.G.SkinnerC．Steve GaskinD．Buckminster Fuller正确答案：D49．What was the Twin Oaks commune base on ?A．The philosophy of “do your own thing”B．Virginaia in the late 1960sC．The ideas of psychologistD．The belief that people must live closely together.正确答案：C50．What is an “archology”?A．A person who studies archaeologyB．A large building where people live closely togetherC．A city in ArizonaD．A technique to control people正确答案：BClozeWho won the World Cup 1994 football game?
