上海高考六选四练习

2019上海高考英语六选四试题适合中等程度偏上分题材针对高考中等程度偏上（A）Getting dressed for the officeIt’s clear that business wear has changed in the last few years--for both men and women. Even traditional business such as law companies have altered their dress codes from “smart” to “smart-casual”. ___1___. What is less clear, however, is what “smart-casual” actually means. I hope to give you a few basic tips here. There are many factors involved: for example, the particular industry you work in, how much contact you have with the public and your position in the company. The seasons even have a part to play--what is acceptable in the summer might not be in the autumn or winter.So, does “smart-casual” mean you can come to work in tracksuit bottoms andsandal s, or does it just mean that you don’t have to wear a tie? ___2___. Fashionable colors for suits for both men and women this season are still the traditional grey, dark blue and black. You see someone wearing grey and it indicates a conservative, professio nal image; dark blue says you’re trustworthy; and black always looks smart and classy. These colors don’t have to look boring, however. Try wearing a shirt or blouse with a splash of color. Pale blue, pink or lilac are better than loud colors like bright pink and dark red.____3__. Men can go for a sports-type jacket, with a shirt or smart jumper. You can wear well-cut trousers made of wool, or a good pair of chinos. Women can wear trouser suits or skirt suits. You can also wear more fashionable trousers and a blouse, or a skirt and top. But be careful; avoid wearing baggy, loose clothes, very short skirts and lots of logos and patterns. If in doubt, go back to the suit. You need a similar attitude to jewelry, bags and other accessories; you should try to resist large earrings and huge, colorful bags. ___4___.答案: DFAC（B）If women are mercilessly exploited(利用) year after year, they have only themselves to blame. Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. ___1__ When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.Changing fashions are nothing more than the intentional creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. ___2__No one can claim that the fashion industry contributes any thing really important to society. Fashion designers are rarely concerned with vital things like warmth, comfort and durability. ___3__There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or delicately picking her way through deep snow in high- heeled shoes.When comparing men and women in the matter of fashion，the conclusions to be drawn are obvious. Do the constantly changing fashions of women's clothes, onewonders, reflect basic qualities of inconstancy and instability? ___4__ Do their unchanging styles of dress reflect basic qualities of stability (稳定)and reliability (可靠)? That is for you to decide.答案:AB, C, A, AC（C）Charity—Humanity’s most kind and generous desire—is a timeless and borderless virtue, dating at least to the dawn of religious teaching. Philanthropy（慈善行为）as we understand it today, however, is a distinctly American phenomenon, inseparable from the nation that shaped it. From colonial leaders to modern billionaires like Buffett, Gates and Zuckerberg, the tradition of giving is woven into the national DNA.____1____ Benjamin Franklin, an icon of individual industry and frugality（节俭）even in his own day, understood that with the privilege of doing well came the price of doing good. When he died in 1790, Franklin thought to future generations, leaving in trust two gifts of 1,000 Ib. of sterling silver—one to the city of Boston, the other to Philadelphia. According to his instruction, a portion of the money could not be used for 200 years.While Franklin’s gifts lay in wait, the tradition he es tablished evolved alongside the young nation. ____2____ Often far less famed men and women have played a critical role in philanthropy’s evolution. One of my pe rsonal heroes is Julius Rosenwald, who helped construct more than 5,300 schools across the segregated（种族隔离）South and opened classroom doors to a generation of African-American students.____3____ The answer is not just to benefit others. Tax reduction, for one, encourages the rich people to give. And philanthropy has long helped improve the public image of everyone from immoral capitalists to the new tech elite. More troubling, however, are the foundational problems that make philanthropy so necessary. Jus t before his death, Dr. Martin Luther King Jr. wrote, “Philanthropy is praise-worthy, but it must not cause the philanthropist to overlook the circumstances of economic injustice which make philanthropy necessary.”Franklin’s gifts represent a broader pri nciple. We are guardians of a public trust, even if our capital came from private enterprise, and our most important obligation is ensuring that the system works more equally and more justly for more people. ____4____ America’s greatest strength is not th e fact of perfection, but rather the act of perfecting.答案: AC, AB, A, C（D）Sex difference in sports interest: What does evolution say?Sports are enormously popular, and one striking pattern is that boys and men are typically much more involved than are girls and women. This sex difference has policy implications, and it raises fundamental questions about the nature of sex differences. A recent review article by Deaner, Balish, and Lombardo (2016), published in Evolutionary Behavioral Sciences, analyzes the relevant theoretical work.First, the authors demonstrated that females' under-representation in sport--both as participants and spectators--generally reflects their lesser sports interest, not merely fewer opportunities for involvement. Moreover, this sex difference occurs in all societies described thus far, from hunters and gatherers to large contemporary societies. _____1_____.Next, the authors explored adaptive, functional hypotheses（猜想）for sports. One hypothesis holds that individuals compete in sports to gain status and that non-participants monitor sports performances so they can evaluate potential competitors and allies（同盟）. _____2_____. Another hypothesis is that sports serve as courtship displays that advertise participant quality to the opposite sex. This hypothesis effectively explains some aspects of females' sports interest._____3_____. Although it is often assumed that socialization practices entirely cause this sex difference, the evidence that socialization plays a role remains doubtful. In particular, no systematic historical comparison has ever shown a decrease in the sex difference. Moreover, several studies indicate that inborn hormones contribute to males' greater sports interest.The points from this review are that the sex difference in sports interest is widespread, partly due to evolutionary pressures that differentially affected males and females, and unlikely to be fully overturned by socialization. _____4_____. Most notably, Title IX is a U.S. law that prohibits sexual discrimination in educational opportunities, including sports, and Title IX is generally implemented under the assumption that females' sports interest is inherently equal to that of males. The present research indicates that this implementation may require revision.答案: DACE（A）In a few years you will be able to order a transcript of your entire genetic code for less than $1,000. ____1____Two different university laboratories have developed test that will reveal the entirety of a baby’s genetic code using just a blood sample f rom the mother plus a drop of saliva(唾液)from the father.Prenatal(出生前的) whole-genome sequencing will provide volumes of information beyond the currently available tests exclusively for genetic disorders such as Down’s syndrome or Tay-Saches disease. The three billion units of code furnished in the new tests will also dwarf(使……相形见的) the relative trickle(零散)of information provided by consumer gene-testing services such as 23andMe, which currently look only at perhaps about one million locations in the genome.____2____Without careful panning, the new prenatal genetics might rob a child of the chance to make decisions best left until adulthood---whether or not to learn, for instance, if a mutation(突变)predicts the inevitability of Huntington’s disease 20 years hence._____3_____. Similar laissez0faire(放住)action to prenatal whole-genome testing could portend(预示)tragedy.Ultimately certain agency will need to develop a comprehensive policy on prenatal whole genome testing. Bioethics scholars wrote an analysis last summer that calls onthe medical community to develop a guide to the most relevant genomic data for future parents. ___4___Without access to a much higher level of refined expertise, the secrets of our offspring’s genetic code will continue to re main an unnerving cipher---or worse.答案: B AC C A（B）Wearable technology is nothing new - activity trackers and smart watches are now as ubiquitous as trainers and glasses. ____1_____ In the not too distant future, it's highly likely that our clothes will be almost as smart as our phones.Given we’ve survived just fine for millennia with the clothes we have now , you might wondering what the point of connected clothing would be. Well, imagine if when you put a jacket in the washing machine, a chip in the jacket automatically puts the machine on the right laundry setting, making life just that little biteasier. _____2______For instance, how it was designed, its sustainability and even a playlist made by the brand.Whilst none of these functions are things we need, the hope is that they'll enhance our clothing and the experience that goes with wearing it. _____3____One company leading the way is clothing care label manufacturer Avery Dennison, who have teamed up with fashion label Rochambeau and Everything to create a bomber jacket with a personalized QR code. The code in the chip then gives the wearer a number of perks such as entry to exclusive clubs, special menus at certain restaurants and a ticket to Rochambeau's next runway show.But internet-connected clothing isn't the only way fashion is combining with technology - programmatic commerce, a concept developed by global ecommerce consultancy Salmon, is set to change the way we buy clothes.______4_____ For example, before you've even realized you've run out of tights, your favorite online retailer has automatically re-ordered some new ones for you based on your repurchasing patterns and an estimation of the average life cycle of your tights.So with connected clothing and homes, it may soon be that when it comes to fashion, we barely have to think about anything at all.答案:E AFC（A）The Science of Risk-SeekingSometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth tasking. 1 _ Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 2 As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.So why aren’t we al l jumping out of airplanes then? Well, even 200, 000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. It all depends on your character.No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 3 To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.4 For the risk-seekers, a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.答案:AB,B,D,AC（B）Does solving a math problem give you a headache? Do you feel nervous when you sit a math exam? ____1____Scientists came to this conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson.Based on their answers, participants were divided into groups. One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject.Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown. ____2____ It was like the pain they would feel, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task.However, scientists saw no strong brain response from people in the second group.Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. “When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong,” explained Ian Lyons from University of Chicago, US, leader of the study. “____3____”More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. “____4____” Lyons said.Based on the study, scientists suggested that things could be done to help students worry less and move past their fear of math, which might mean they perform better in tests.答案: C D E A（C）Suppose you become a leader in an organization. It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help understand why people undertake volunteer word and what keeps their interest in the work.Let’s begin with the question of why people volunteer. ______1_________For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortun ately, these programs can shift people’s wish of participating from an internal factor (e.g. “I volunteer because it’s important to me”) to an external factor(e.g., ‘ I volunteer because I’m required to do so .”) . When that happens people become less likely to volunteer in the future. ________2_________Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. _____3_____ the researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience.”Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. _______4_______ . Participants indicated the degree to which the social rolemattered by responding to statements such as “V olunteering in Hospital is an important part of who I am.” “ Consistent with the researchers “ expectations, they found a positive correlation between the strength of role identity and the length of time people continued to volunteer. These results, once again , lead to concrete advice:” Once an individual begins volunteering ,continued efforts might focus on developing a volunteer role identity ---- Item like T-shirts that allow volunteers to be recognized publicly for t heir contribution can help strengthen role identity.”答案:FBEC（D）Exoplanets :The Hunt Is OnToday scientists believe that planets could outnumber the stars. For centuries, scientists and natural philosophers have proposed that stars in the night sky have planetary systems similar to our own solar systems. The existence of extrasolarplanets, or exoplanets, has long been discussed. ___1__ Although not the first exoplanet discovery, a planet near a sun-like star was discovered by astronomers in 1995. This kicked off an era of exoplanet hunting, with thousands of discoveries and confirmations following in its wake.___2__ However, in 2015 NASA’s Kepler space telescope found its first Earth-sized planet in a “habitable” zone. This is the distance from a star where surface temperature of a planet wouldn’t be too hot or too cold for liquid water. So far, only a small slice of our galaxy, the Milky Way, has been explored. Even so, scientist have confirmed over 3500 exoplanets, with more being added every day.To detect exoplanets, scientists use data from a variety of sources. Large ground- based telescopes, earth- circling and sun- circling satellites all collect different types of information. Because exoplanets are so far away and very lose to stars, it is very difficult to see them directly ____3__. For example, when an exoplanet moves between its star and us, it causes a small drop in the star’s brightness. Measuring this drop is the transit （凌日）method of discovery. NASA’S Kepler space telescope has discovered many exoplanets in this way.As a planet circles a star, it pulls on it and causes it to shake. __4___. Measuring these slight changes is the radial velocity（径向速度）method of discovering planets. It is one of the most productive methods for finding and confirming exoplanets.These are just two examples of the many methods scientists use in their hunt for exoplanets, hoping for more information and enhanced detail. As time progresses and technology improves, who knows what else we may find!答案: EBAC（A）In the 19 century, millions of European went to the USA because they wanted to find a better life. Many of them couldn't find work in cities like New York._67_ The people, called settlers, travelled west through the mountains on the Oregon Trail.Some of these people hoped to find gold in California. The journey sometimes took more than one year. There are a lot of films, called Westerns, about the settlers on the trail. In most of the film, we see the native Americans(American Indians) attacking the settlers, and the "Indians" killing many white people._68_ In fact, most of them were very helpful to the settlers._69_ many of them walked 3200 kilometers, the whole length of the trail. They had wagons, but the wagons were often too full, so people could not travel in them. Many parents also had to carry their small children. The people were very poor andmany did not even have shoes— they walked the whole trail bare foot, in extremely cold temperature.More than 50,000 people, including many women and children, died on the trail.A lot of people died from illnesses like cholera, because the drinking water wasn’t clean._70_Many people died under the wheels of wagons, for example, and from accidental gunshots.Keys: 67~70 D AC AB B。

(一)Stage frightA. Pick up the dish with the remain ing food.B. Proper food is a basic necessity for your puppies.C. Remember to give your puppy the food he would like to have.D. It can also cause an upset stomach due to an unbalanced diet.E. One example is that extra helpings of nutrients do harm to digestive organs.F. It’s good to provide the extra nutrients a puppy needs until he grows larger.Puppy foodA puppy (young dog) is a precious addition to any family. The excitement of bringing home a little furry friend will always live in our memories. Like all of us, though, your puppy must have adequate nutrition right from the start to make certain tha t it’ll have a long and healthy life.1 You might ask yourself what is the best for your new pet with all of the different varieties on the market in all of their attractive packaging. Some dry food produced specially for puppies is the best for the development of their teeth. A further benefit is that it is less expensive than the canned food.Contrary to the belief of many first-time puppy owners, it is not always the best idea to purchase food that is too high in calcium (钙), protein, and vitamin levels. 2 In addition, a high intake of calcium is associated with bone disease in large-breed dogs. If you have a “small-breed” puppy, you can buy that kind of food.It is not a good idea to feed the food you eat to your puppy frequently, as your puppy may become selective about food. 3 Some people think that dog biscuits and other treats are fine, but they should not be a main part of a puppy’s diet.Young puppies should be fed three times a day. Each puppy is unique, so feeding them twice a day is acceptable. After ten to twelve weeks of age, feed your puppy twice per day. Allow your puppy to eat as much as he would like in fifteen minutes. 4 If you let your puppy eat too much or too often by keeping food accessible at all times, he may become overweight and have health problems as an adult. Like humans, your puppy will not enjoy the food any longer if it is there at all times.(三)organizations and religious institutions. Although children choose their own spouses, they still hope their parents will approve of their choices.Parents feel that children should make major life decisions by themselves in many families. A parent may try to influence a child to follow a particular profession but the child is free to choose another job. 2 A son may deliberately decide not to go into his father’s business because of a fear that he will lose his independence in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family.3 It is not like we Chinese. Parents are rulers and masters. We Chinese love our parents with fear and total respect. In America children always have their own opinions and evencan talk about some sensitive problems with their parents, like family financial situation, the relationship between mother and father, and even sex._ 4 Therefore, it is contrary that on one hand, Americans admire independence and equality that they don’t want to make sacrifice to make up a family, but o n the other hand, Americans think highly of family in their value system.in a wheelchair to have room to get in or out of their car. __3__Some walkways have handrails next t o them to help those who require extra assistance. Whether it is a blind person seeking guidance or an elderly person seeking support, the rail is there for walking. Sometimes the rail is blocked, by a parked bicycle for instance, and consequently made useless. __4__ People who are informed of the rail’s use would be less likely to mistake it for a bike rack.Meeting some of the people who are affected by the lack of education about accommodationsTeen peer pressureTeen peer pressure is the influence a teenager’s social group has on him or her. As adolescents enter the teen years, they usually begin to focus more on their peers or friends.__1__Peers influence most aspects of a teenager life, including how teenagers dress, what music they listen to, and what kind of activities they are involved in.__2__Good friends can encourage teenagers to do well in school, get involved in positive activities, eat healthy foods, and avoid drugs, alcohol, and other risky activities. Friends also help teenagers learn good social skills and better ways to communicate and work out problems. They always give teenagers good advice.Negative peer pressure is when teenagers feel pressured to do something they know is wrong, such as smoking, drinking, stealing, or cutting class.__3__This is because they want to be liked or fit in, they are afraid of being made fun of, or they want to try something other teenagers are doing.It is important for teenagers to learn how to deal with peer pressure. There are a lot of things1Watch for misleading l anguage. Some studies will find that a behavior “contributes to” or is “associated with” an outcome；this does not mean that a certain course must lead to a certain result.2 Carefully read or listen to information in order to fully understand it.Use your common sense. If a report seems too good to be true, probably it is. Be especially careful of information contained in advertisements. 3 Evaluate “scientific” statements carefully, and be aware of quackery (江湖骗术).4 Friends and family members can be a great source of ideas and inspiration, but each of us needs to find a healthy lifestyle that works for us.Developing the ability to evaluate reasonably and independently about health problems will serve you well throughout your life.My theory is that the female brain is mainly built for empathy — the ability to understandwrong. It continually, and without your conscious permission, scans your life, even when you are asleep, in dreams and nightmares. 1 When it finds one, it worries it.Along with depression and anger, anxiety is one of the bad faces of worries. 2 Controlled by anxiety, you will feel a lack of security and confidence. When anxiety is severe and pained, it can be a sign of a disorder, such as panic or terror.Although anxiety seems to have a biological basis, it is habit-forming for many of us. Some of our anxious feelings are in fact wasted energy. Anxiety has gotten out of hand when it is pointless and repeated. When you are faced with a problem at work, before taking a test, or making an important decision, you will feel anxious. When you are controlled by anxiety, you are unable to control your emotions to the point of it changing your daily routine and habits. 3 Or you find you are usually anxious at work or around your family.At times, you should listen to the message of your negative emotions, as uncomfortable as they may be, and change your outward life rather than your emotional life. 4 If you are。

Passage1UrbanizationUntil relatively recently,the vast majority of human beings lived and died without ever seeing a city.The first city was probably founded no more than5,500years ago.1_.In fact,nearly everyone lived on farms or in tiny rural(乡村的)villages.It was not until the20th century that Great Britain became the first urban society in history---a society in which the majority of people live in cities and do not farm for a living.Britain was only the beginning.2_.The process of urbanization---the migration(迁移)of people from the countryside to the city---was the result of modernization,which has rapidly transformed how people live and where they live.In1990,fewer than40%of Americans lived in urban areas.Today,over82%of Americans live in cities.Only about2%live on farms.The rest live in small towns.Large cities were impossible until agriculture became industrialized.Even in advanced agricultural societies.It took about ninety-five people on farms to feed five people in cities._3.Until modern times,those living in cities were mainly the ruling elite(精英)and the servants,laborers and professionals who served them.Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.Over the past two centuries,the Industrial Revolution has broken this balance between the city and the country.4_.Today,instead of needing ninety-five farmers to feed five city people,one American farmer is able to feed more than a hundred non-farmers.A.That kept cities very small.B.The effects of urban living on people should be considered.C.Soon many other industrial nations become urban societies.D.But even200years ago,only a few people could live in cities.E.Modernization drew people to the cities and made farmers more productive.F.Modern cities have destroyed social relations and the health of human beings.参考答案：DC AE解析：首先对这六个选项进行分析，查找相应的关键词A.That kept cities very small.B.The effects of urban living on people should be considered.C.Soon many other industrial nations become urban societies.D.But even200years ago,only a few people could live in cities.E.Modernization drew people to the cities and made farmers more productive.F.Modern cities have destroyed social relations and the health of human beings.1，前一段讲解了城市的早期起源，最后一句“第一座城市在5,500年之前发现的，”横线后一句用“事实上，几乎每个人都住在农场里或者小的乡村”链接，所以表示转折链接，所以选D（语义层次——转折关系）2，前一句表示“英国仅仅是个开始”，后句“城市化过程是现代化的结果”。

做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。

总之，在最后的复习阶段，学生们不要加大练习量。

在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。

英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。

越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。

2017上海高考英语阅读新题型六选四(一) Most drinks stating that they are fruit-flavored （水果味道的） contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission． "Shoppers need to check the labels（标签）before buying drinks, though sometimes the actual content can be non-existent," said Food Commission spokesperson Lan Tokelove．"Food production is highly competitive．___1 __ It will increase profits, and consumers won't always realize they are being tricked." Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors．Researchers analyzed the contents of 28 strawberry-flavored products sold in stores． __2_ Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit．In addition, each juice box contained nearly eight teaspoons of sugar． _3 _ Let's take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.　The Food Commission suggested all flavors used in a product should be listed on the packaging.Consumers have the rights to know clearly about what they have bought．Under current UK law. Food packages do no not have to distinguish between natural and artificial flavoring. "Describing a product as strawberry flavor and covering the surface of the packed with pictures of stawberries is misleading. _4_ Unfortunatcly, it is also legal and widespread," Tokelove said. A．The products which contain real fruit are popular with people． B．Even products advertised as more natural often contained no fruit． C．They found that about 60 percent of them didn't contain any fruit at all． D．If companies can cut their costs by using flavoring, they are likely to do so． E．It is important and necessary to demand a small amount of flavoring in the products． F．Actually the product contains just a tiny percentage of strawberry oreven no fruit at all．(二)On a typical hot August day in Xianyou County, Fujian Province, Zeng Demei, a retired worker in his seventies, hurries down a busy street．In his hand is a black leather bag．Zeng opens his bag, taking out two forms．1_____.Each of the forms contains detailed information of a student．On his arrival two hours later a woman greets him and leads him to her office where another man is waiting．They are the two village officials．They inspect the forms handed to them by Zeng and immediately recognize the girls． 2 _____ ? "It’s a pity but it doesn't matter．" says Zeng, who wastes no time in deciding to look for the remaining child, Su Qiuju．After half an hour, they stop outside a small house made of mud brick．A middle-aged man and a girl in a faded pink dress greet them．Su Qiuju is eight years old．She was forced to drop out of school after both her parents died．She is now living with her uncle who cannot afford his own children's education．However, the year of education Su Qiuju did complete was a successful one． 3 _____ ．When they are about to leave, Zeng says, "I must find a supporter for this girl to sponsor her education．" Zeng has made it his retirement task to help children complete their schooling．Back in 1999, Zeng took part in a campaign started by the local women's organization to help students from poor families．He was so overcome by the tough situation of many poor children ?that he donated all his money to help out a girlHis task had begun and since then he has spent his time persuading his friends and neighbors and others to donate money．"To me, children's education is the most important． 4 I have to find sufficient funding before the school opens in September．"When asked how long he will keep up his vital work as the community's guardian angel, he has a simple reply．" Not until my eyes can't see, and my feet can't move．"A．They were having problems with their schoolworkB．These are for the two girls he's going to visit this morningC．They live in a small village not very far, though only one of the girls is still living at homeD．She displayed a talent for handwriting, writing her three-character name neatly and beautifullyE．The thought of students dropping out of school bothers me so much that I can't get to sleep at nightF．Of course, some people question why I would want to give up my retirement to go to so much trouble(三)Taking good notes is a time-saving skill that will help you to become a batter student in several ways. First, the simple act of writing something down makes it easier for you to understand and remember it. Second, your notes are excellent materials to refer to when you are studying for a test. Third, note-taking offers variety to your study time and helps you to hold your interest.You will want to take notes during classroom discussions and while reading a textbook or doing research for a report.1 Whenever or however you take notes, keep in mind that note-taking is a selective process.2 The following methods may work best for you.●Read the text quickly to find the main facts and ideas in it.●Carefully read the text and watch for words that can show main points and supporting facts.● Write your notes in your own words.● 3● Note any questions or ideas you may have about what was said or written.As you take notes, you may want to use your own shorthand(速记). When you do, be sure that you understand your symbols and that you use them all the time.4A. Use words, not complete sentences.B. There are three practical note-taking methods.C. You must write your notes on separate paper.D. Otherwise, you may not be able to read your notes later.E. you will also want to develop your own method for taking notes.F. That means you must first decide what is important enough to include in your notes.(四)　Building Trust in a Relationship Again Trust is a learned behavior that we gain from past experiences._1- Trust is a risk.But you can’t be successful when there’s a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake. Unfortunately，we’ve all been victims of betrayal.Whether we’ve been stolen from，lied to，misled，or cheated on，there are different levels of losing trust.Sometimes people simply can’t trust anymore.—2--It’s understandable，but if you’re willing to build trust in a relationship again，we have some steps you can take to get you there..Learn to really trust yourself. Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being. -3--If you’ve been betrayed，you are the victim of your circumstance.But there’s a difference between being a victim and living with a “victim mentality”.At some point in all of our lives，we’ll have our trust tested or violated. ?You didn’t lose “everything”.Once trust is lost，what is left? Instead of looking at the situation from this hopeless angle，look at everything you still have and be thankful for all of the good in your life.-4-- Instead，it’s a healthy way to work through the experience to allow room for positive growth and forgiveness. A.It is putting confidence in someone. B.Stop regarding yourself as the victim. C.Remember that you can expect the best in return. D.They’ve been too badly hurt and they can’t bear to let it happen again. E.This knowledge carries over in their attitude toward their future relationships. F.Seeing the positive side of things doesn’t mean you’re ignoring what happened.(五). This Way to Dreamland Daydreaming means people think about something pleasant，especially when this makes them forget what they should be doing.Daydreamers have a bad reputation for being unaware of what’s happening around them.They can seem forgetful and clumsy.- 1- They annoy us because they seem to be ignoring us and missing the important things. But daydreamers are also responsible for some of the greatest ideas and achievements in human history.-2 --Can you imagine what kind of world we would have without such ideas and inventions? So how can you come up with brilliant daydreams and avoid falling over tree roots or otherwise looking like a fool? First，understand that some opportunities(机会) for daydreaming are better than others.Feeling safe and relaxed will help you to slip into daydreams.—3- And if you want to improve your chances of having a creative idea while you’re daydreaming，try to do it while you are involved in another task—preferably something simple，like taking a shower or walking，or even making meaningless drawings. It’s also important to know how to avoid daydreams for those times when you really need to concentrate.“Mindfulness”，being focused，is a tool that some people use to avoid falling asleep.—4- Finally，you never know what wonderful idea might strike while your mind has moved slowly away. Therefore，it’s a good idea to keep a notebook or voice recorder nearby when you’re in the daydream zone.Always remember that your best ideas might come when your head is actually in the clouds. A.Having interesting things to think about also helps. B.They stare off into space and wander by themselves. C.Without wandering minds，we wouldn’t have relativity，Coke or Post-it notes. D.At one time，daydreaming was thought to be a cause of some mental illnesses. E.It involves slow，steady breathing for self-control that helps people stay calm and attentive. F.Daydreams are often very simple and direct，quite unlike sleep dreams，which may be hard to understand.答案:(一) D C B F (二).BCDE (三). EFAD (四) A. D B F(5). BCAE。

第8讲高频词2+六选四2+四字短语+记叙文原卷版一、高频词二、六选四高考英语六选四阅读解题的十大技巧技巧一：从细节逻辑上判断---因果关系在做题时最重要的是要读懂空白前后的句子，明白这几句话的确切意思，然后根据意思的连贯性或逻辑性从选项中选取正确答案。

在读懂意思的基础上，判断它们之间的关系来进一步确认答案。

因果关系主要指前后的句子有着原因和结果之间的关系，这种关系往往说明了前因后果或者前果后因等情况。

表示因果关系的连词有as a result结果，thus/therefore因此，so (such)...如此------以至于等。

技巧二：从细节逻辑上判断---转折关系转折关系主要指英语行文中后句对前句构成逆转逻辑关系。

如果空格前后两句话之间是逻辑上的逆转，则空格处很有可能是个转折逻辑的句子。

表示转折关系的连接词有：However然而, nevertheless仍然，然而，不过, nonetheless尽管如此，依然，然而, still还；然而, though可是，不过，然而, yet然而, in spite of不顾，不管, at any rate无论如何，至少, in any case无论如何，不管怎样, whoever无论是谁, whatever无论什么，on the contrary正相反, in contrast与此相反, 相比之下, by contrast相反, 相比之下, in comparison比较起来，比较地, by comparison相比之下, conversely相反(地), otherwise否则；除此以外，not---but不是-----而是，as well也等。

技巧三：从细节逻辑上判断---例证关系前后句的某句是为了证明另一句而举的例子。

例证的形式多样，但就其本质而言无非是思维上的形象（例子、类比等）和抽象（观点）的辩证关系，用到的思维过程无非就是基本的归纳（从例子到观点）和推理（从观点到例子）。
