4. Passage Eight Wisdom teeth are normally the last teeth to appear. This usually happens when people are in their late teen years or early twenties—in other words， when they are older and wiser. Wisdom teeth are chewing teeth， at the back of the mouth. They can grow into place normally and never cause a problem. But often there is not enough room for them in the mouth. They might crowd other teeth. Sometimes they even push sideways through the gums (牙床). An impacted wisdom tooth is one that fails to completely rise through the gum—the term is 【erupt】. Wisdom teeth that only partially erupt can leave space for bacteria to enter around the tooth. Infection is a risk in these cases. Wisdom teeth that are not well in place and become impacted are often removed. People should have the placement of their wisdom teeth examined between the ages of sixteen and twenty. X-rays can show wisdom teeth that are below the gums. The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. Removal is also advised if there is a chance that poorly placed wisdom teeth will damage other teeth. And removal is called for in cases where fluid collects around a wisdom tooth that is partly or fully below the gum. But why do we have wisdom teeth if we often need to get them removed? One theory has to do with our diets. Scientists say the diet of prehistoric humans probably required more chewing teeth. Life was probably alittle rougher on the teeth back then， too. So it was good to have extras. The American Association of Oral and Maxillofacial (上颌面的) Surgeons says young adults are the best candidates for wisdom teeth removal. The group says older patients may be at greater risk for disease in the tissue surrounding the teeth. After surgery， there can be swelling of the gums and face and some pain. Both can be treated with cold wraps and medication (药物治疗). Humans have wisdom teeth probably because ( ) .

A. our ancestors needed to chew more when they grew up

B. our ancestors’ teeth grew at late teens or early twenties

C. our ancestors ate foods without cooking

D. our ancestors had very tough lives

2. Passage Twenty-Seven Out of all the students who enroll in a massive open online course 【MOOC】， only about 5 percent complete the course and receive a certificate of accomplishment. This statistic is often cited as evidence that MOOCs are fatally flawed (有缺陷的) and offer little educational value to most students. Yet more than 80 percent of students who fill out a post-course survey say they met their primary objective. How do we look at these two facts? We’re used to focusing on completion rates in higher education， but they’re not the only—or even the most meaningful—indicator of engagement in open online courses. With no cost to enroll， no punishment for dropping out， and little reward for actually earning a certificate， MOOCs are fundamentally different from traditional classes—and students use them in fundamentally different ways. Data from more than 1.8 million students enrolled in 36 MOOCs offered by the University of Pennsylvania show that students treat MOOCs like a buffet (自助餐)， sampling the material according to their interests and career goals. Some are curious about the subject matter and just watch one or two video lectures; others use the discussion forums to connect with their intellectual peers around the world. Of all enrolled students， nearly 60 percent watch at least one video， complete at least one assignment， or post at least once in a forum. So focusing on the tiny fraction of students who complete a MOOC is misguided. The more important number is the 60 percent engagement rate. Students may not finish a MOOC with a certificate of accomplishment， but the courses nonetheless meet the educational goals of millions. In Para. 2， the author stresses ( ) .

A. the primary objective of MOOC students

B. the significance of completion rates in education

C. the strengths and weaknesses of open online courses

D. the differences between MOOCs and traditional classes

1. Passage Twenty-Three Washington 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. The main point of the first paragraph is that Washington Irving was ( ) .

A. America’s first man of letters

B. a writer who had great success both in and outside his own country

C. a man who was able to move from literature to politics

D. a man whose personal charm enabled him to get by with basically inferior work

1. Passage Four Did your mum and dad go to university， or did they leave school and go straight to the Job Centre? The educational experience of parents is still important when it comes to how today’s students choose an area of study and what to do after graduation， according to the Future-track research in the UK. The research was done by the Higher Education Careers Service Unit. It plans to follow university applicants for six years from 2006 through their early careers. The first year’s findings come from a study of 130，000 university applicants. They show significant differences in prospective students’ approach to higher education， depending on whether their parents got degrees 【second-generation applicants】 or didn’t 【first-generation applicants】. First-generation applicants were more likely to say that their career and employment prospects were uppermost in their minds in deciding to go to university. About one-fifth of this group gave “to enable me to get a good job” as their main reason for choosing high education. And 37 percent said that a degree was “part of my career plan” . A young person coming from a non-professional household where finances are stretched may find the idea of learning for its own sake to be a luxury. This explains the explosion in vocational course. At Portsmouth University， first-year student Kim Burnett， 19， says that she specifically chose her degree in health research management and psychology to get a secure， well-paid job. Harriet Edge， 20， studying medicine at Manchester University， also wanted job security. Her parents lacked college degrees， though the fact that her uncle is a doctor appears to have influenced her choice. “Medicine is one of those fields where it’s pretty likely you’ll get a job at the end. That’s a big plus， as the debt levels after five years of study are going to be frightening，” she says. Many experts believe that this situation affects those with no family tradition of higher education far more keenly. The fact that 26 percent of respondents said that they needed more advice implies that some students may end up feeling that their higher education investment was not worthwhile. For those with graduate parents， this lack of guidance may， the researchers suggest， be less of a problem. “But， for those without the advantages， lack of access to career guidance before applying for higher education leaves them exposed to making poorer choices，” the survey concludes. The main idea of the passage is that ( ) .

A. parents’ experiences are more important for their children’s education

B. parents’ careers are vitally important for their children’s degrees

C. students’ approach to higher education correlates with their parents’ educational experience

D. students’ career and employment prospects are decided by their parents

3. Passage Fifteen Big data can be defined as information that is too big or complex to be contained or processed by any one machine or person. As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy. When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology. Now， he is part of the big data industry that includes Google and Facebook. Dailly’s research company， Morar Consulting， started three years ago with five employees. The company’s earnings have increased by 25% each year. It now employs 90 people. “What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said. He noted the importance of working with people with different skills. “We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and salespeople，” Dailly said. Companies like Dailly’s employ recent college graduates. The industry profits from the ideas of these young men and women. New forms of data also make it possible for some observers to predict the future. They are more valuable to companies than the traditional forms of data recording or reporting. “We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done. That helps people take proper action in advance. This makes it much more useful for strategy.” Julian Dailly dismisses concerns that computers have finally taken control of our daily lives. “Some may worry that humans will be allowed to be replaced by machines. I think it’s a fantasy.” The company’s staff is characterized by all the following EXCEPT ( ) .

A. fresh ideas

B. young age

C. mixed education backgrounds

D. rich experience in the field

1. Passage Two When older people can no longer remember names at a cocktail party， they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong. Instead，the research finds， the aging brain is simply taking in more data and trying to examine carefully a lot of information， often to its long-term benefit. Some brains do deteriorate with age. But for most aging adults， researchers say， much of what occurs is a gradually widening focus of attention that makes it more difficult to get hold of just one fact. Although that can be frustrating， it is often useful. “It may be that distractibility is not， in fact， a bad thing，” said Shelley H. Carson， a psychology researcher at Harvard. “It may increase the amount of information available to the conscious mind. ” For example， in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases， adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean， older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling (结结巴巴地念) over the extra information， but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers， the older adults responded much better than the students. “For the young people， it’s as if the distraction never happened，” said a researcher of the review， Lynn Hasher， a professor of psychology at the University of Toronto. “But for older adults， because they’ve retained all this extra data， they’re now suddenly the better problem solvers. They can transfer the information they’ve soaked up from one situation to another.” Such tendencies can yield big advantages in the real world， where it is not always clear what information is important， or will become important. For instance， a seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. According to the first paragraph， it can be inferred that ( ) .

A. the brainpower does not always decline with age

B. older people feel sad for they can’t remember names

C. cocktail parties are popular among older people

D. there are a growing number of people studying the aging brain
