Each passage is followed by five questions. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice by writing the corresponding letter on the Answer Sheet(机读纸).7．Passage OnePeople have grown taller over the last century, with South Korean women shooting up by more than 20cm on average, and Iranian men gaining 16.5cm. A global study looked at the average height of 18-year-olds in 200 countries in 1914 and 2014.The results reveal that while Swedes were the tallest people in the world in 1914, Dutch men have risen from 12th place to claim top spot with an average height of 182.5cm. Larvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later, with an average height of 169.8cm.James Bentham, a co-author of the research from Imperial College, London, says the global trend is likely to be due primarily to improvements in nutrition and healthcare. “An individual's genetics has a big influence on their height, but once you average over whole populations, genetics plays a less key role” he added.A little extra height brings a number of advantages, says Elio Riboli of Imperial College. “Being taller is associated with longer life expectancy,” he said. “This is largely due to a lower risk ofdying of cardiovascular (心血管的) disease among taller people.”But while height has increased around the world, the trend in many countries of north and sub-Saharan Africa causes concern, says Riboli. While height increased in Uganda and Niger during the early 20th century, the trend has reversed in recent years, with height decreasing among 18-year-olds.“One reason for these decreases in height is the economic situation in the 1980s,” said Alexander Moradi of the University of Sussex. The nutritional and health crises that followed the policy of structural adjustment, he says, led to many children and teenagers failing to reach their full potential in terms of height.Bentham believe the global trend of increasing height has important implications. “How tall we are now is strongly influenced by the environment we grew up in,” he said. “If we give children the best possible start in life now, they will be healthier and more productive for decades to come.”（5分）(1)．What does the global study tell us about people’s height in the last hundred years?（1分）A．There is a remarkable difference across continents.B．There has been a marked increase in most countries.C．The increase in people’s height has been quickening.D．The increase in women’s height is bigger than in men’s.(2)．What does James Bentham say about genetics in the increase of people’s height?（1分）A．It counts less than generally thought.B．It outweighs nutrition and healthcare.C．It impacts more on an individual than on population.D．It plays a more significant role in females than in males.(3)．What does Elio Riboli say about taller people?（1分）A．They tend to live longer.B．They enjoy an easier life.C．They generally risk fewer fatal diseases.D．They have greater expectations in life.(4)．What do we learn about 18-year-olds in Uganda and Niger?（1分）A．They grow up slower than their peers in other countries.B．They are actually shorter than their earlier generations.C．They find it hard to bring their potential into full play.D．They have experienced many changes of government.(5)．What does James Bentham suggest we do?（1分）A．Watch closely the global trend in children's development.B．Make sure that our children grow up to their full height.C．Try every means possible to improve our environment.D．Ensure our children grow up in an ideal environment.8．Passage TwoIf you were like most children, you probably got upset when your mother called you by a sibling's (兄弟姐妹) name. How could she not know you? Did it mean she loved you less?Probably not. According to the first research to tackle this topic head-on, misnaming the most familiar people in our life is a common cognitive (认知的) error that has to do with how our memories classify and store familiar names.The study, published online in April in the journal Memory and Cognition, found that the “wrong” name is not random but is invariably fished out from the same relationship pond: children, siblings, friends. The study did not examine the possibility of deep psychological significance to the mistake, says psychologist David Rubin, “but it does tell us who’s in and who’s out of the group”. The study also found that within that group, misnamings occurred where the names shared initial or internal sounds, like Jimmy and Joanie or John and Bob. Physical resemblance between people was not a factor. Nor was gender.The researchers conducted five separate surveys of more than 1,700 people Some of the surveys included only college students; others were done with a mixed age population. Some asked subjects about incidents where someone close to them--- family or friend---had called them by another person’s name. The other surveys asked about times when subjects had themselves called someone close to them by the wrong name. All the surveys found that people mixed up names within relationship groups such as grandchildren, friends and siblings but hardly ever crossed these boundaries.In general, the study found that undergraduates were almost as likely as old people to make this mistake and men as likely as women. Older people and women made the mistake slightly more often, but that may be because grandparents have more grandchildren to mix up than parents have children. Also, mothers may call on their children more often than fathers, given traditional gender norms. There was no evidence that errors occurred more when the misnamer was frustrated, tired or angry.（5分）(1)．How might people often feel when they were misnamed?（1分）A．Unwanted.B．Unhappy.C．Confused.D．Indifferent.(2)．What did David Rubin's research find about misnaming?（1分）A．It is related to the way our memories work.B．It is a possible indicator of a faulty memory.C．It occurs mostly between kids and their friends.D．It often causes misunderstandings among people.(3)．What is most likely the cause of misnaming?（1分）A．Similar personality traits.B．Similar spellings of names.C．Similar physical appearance.D．Similar pronunciation of names.(4)．What did the surveys of more than 1,700 subjects find about misnaming?（1分）A．It more often than not hurts relationships.B．It hardly occurs across gender boundaries.C．It is most frequently found in extended families.D．It most often occurs within a relationship groups.(5)．Why do mothers misname their children more often than fathers?（1分）A．They suffer more frustrations.B．They become worn out more often.C．They communicate more with their children.D．They generally take on more work at home.得分阅卷人五、Part II Reading Comprehension Section B (共1题，共10分)9．Directions: In this section, you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Please write your answers on the Answer Sheet (机读纸).1.How you approach studying matters(A-C)2.Where you study is important(D-E)3. Bring everything you need, nothing you don’t(F-G)4. Outline and rewrite your notes(H)5. Practice by yourself or with friends(I)6.Make a schedule you can stick to(J)7. Take breaks (and rewards!)(K)8. Keep healthy and balanced(L)9. Know what the expectations are for the class(M-N)（10分）A．Students grapple with many issues in their lives, and because of all of the competingthings for your attention, it’s hard to concentrate on studying. And yet if you’re inschool, you have to do at least a little studying in order to progress from year to year.The key to effective studying isn't cramming or studying longer, but studying smarter.You can begin studying smarter with these nine proven and effective study habits.B．Too many people look at studying as a necessary task, not an enjoyment or anopportunity to learn. That's fine, but researchers have found that how you approachsomething matters almost as much as what you do. Being in the right mindset isimportant in order to study smarter,C．Sometimes you can’t “force” yourself to be in the right mindset, and it is during such times that you should simply avoid studying If you’re distracted by a relationship issue, an upcoming game, or finishing an important project, then studying is just going to be an exercise in frustration. Come back to it when you’re not preoccupied (or obsessed!) by something else going on in your life.D．A lot of people make the mistake of studying in a place that really isn’t conductive to concentrating. A place with a lot of distractions makes for a poor study area. If you try and study in your dorm room, for instance, you may find the computer, TV, or a roommate more interesting than the reading material you’ re trying to digest.E．The library, a corner in a student lounge or study hall are good places to check out. Make sure to choose the quiet areas in these places, not the loud, central gathering areas. Investigate multiple places on-campus and off-campus; don't just pick the first one you find as “good enough” for your needs and habits. Finding an ideal study place is important, because it’s one you can reliably count on for the next few years. F．Unfortunately, when you find an ideal place to study, sometimes people bring things they don’t need. For instance, while it may seem ideal to type notes into a computer to refer back to later, computers are a powerful distraction for many people because they can do so many different things. Playing games, going online, surfing the Web, and answering emails are all wonderful distractions that have nothing to do with studying. So ask yourself whether you really need a computer to take notes, or whether you can make do with the old fashioned paper and pen or pencil.G．Don’t forget the things you need to study for the class, exam or paper you’re focusing on for the study session. Nothing is more time consuming and wasteful than having to run back and forth regularly because you forget an important book, paper, or some other resource you need to be successful.H．Most people find that keeping to a standard outline format helps them boil information down to its most basic components. People find that connecting similar concepts together makes it easier to remember when the exam comes around. The important thing to remember in writing outlines is that an out-line only works as a learning tool when it is in your own words and structure. Every person is unique in how they put similar information together (called “chunking” by cognitive psychologists). So while you’re welcomed to copy other people’s notes or outlines, make sure you translate those notes and outlines into your own words and concepts. Failing to do this is what often causes many students to stumble in remembering important items. I．The old saying, practice makes perfect, is true. You can practice by yourself by testing yourself with either practice exams, past quizzes, or flash cards(depending on what kind of course it is and what's available). If a practice exam isn't available, you canmake one up for yourself and your classmates. If a practice or old exam from a course is available, use it as a guide ___do not study to the practice or old exam! Such exams help you understand the breadth of content and types of questions to expect, but are not the actual material to study for.J．Too many people treat studying as the thing to do when you get around to it or have some spare time. But if you schedule study time just as your class time is scheduled, you’ll find it becomes much less of a hassle in the long run. Instead of lastminute cramming sessions, you’ll be better prepared because you haven’t put off all the studying into one 12-hour marathon. Spending 30 or 60 minutes every day you have a class studying for that class before or after is a lot easier and will allow you to actually learn more of the material.K．Because so many people view studying as a chore or task, it’s human nature to avoid it. If, however, you find rewards to help reinforce what you’re doing, you may be pleasantly surprised by the change you may find in your attitude over time.Rewards start by chunking study time into manageable components. Studying for 4 hours at a time with no breaks is not realistic or fun for most people. Studying for 1 hour, and then taking a 5-minute break and grabbing a snack is usually more sustainable and enjoyable. Divide study time into segments that make sense and work for you. If you have to digest a whole textbook chapter, find sections in the chapter and commit to reading and taking notes on one section at a time. Maybe you only do one section in a sitting, maybe you do two. Find the limits that seem to work for you.L．It’s hard to live a balanced life while in school, I know. But the more balance you seek out in your life, the easier every component in your life becomes. If you spend all of your time focusing on a relationship or a game, you can see how easy it is to be out of balance. When you're out of balance, the things you’re not focusing on such as studying become that much harder. Don't spend all of your time studying ___ have friends, keep in touch with your family, and find interests outside of school that you can pursue and enjoy.M．Different professors and teachers have different expectations for their students. While taking good notes and listening in class are good starts, you can do better by spending some time with the instructor or professor's assistant. Talking to the instructor early on especially if you foresee a difficult course ahead ___ will help you understand the course requirements and the professor's expectations.If you get a particularly bad grade on a paper or exam, talk to the instructor. Try and understand where things went wrong, and what you can do in the future to help reduce it from happening again.Don’t forget to learn!N．Studying isn’t just about passing an exam, as most students look at it as. Studying isan effort to actually learn things, some of which you might actually care about. So whileyou’ll have to take your share of classes that have little or nothing to do with yourinterests, you should still look for interesting things to take away from every experience.(1)．___ There are always interesting things to be found in what you learn.（1分）(2)．___ You should space your work out over shorter periods of time and not try to cram all ofyour studying into just one or two sessions.（1分）(3)．___ Past test papers are only useful in that they give you a general idea of the subject areas tofocus on and help you identify the style of the questions.（1分）(4)．___ It is important to know what the professors will be expecting of you when you sign up fortheir courses.（1分）(5)．___ Studying can be a problem when you aren’t in the mood for it.（1分）(6)．___ Only bring the necessary study tools with you when you go to your ideal study place.（1分）(7)．___ Notes are only useful and helpful when they are written using your own words andconcepts.（1分）(8)．___ Finding a positive study environment is very important.（1分）(9)．___ In order to study efficiently, you have to have the right attitude.（1分）(10)．___ Information reviewed amid distractions is less likely to be remembered.（1分）得分阅卷人六、Part II Reading Comprehension Section C (共1题，共10分)10．Directions: In this section, there is a passage with ten blanks.
