T【解析】【原文】Yellowstone is the largest park in the United States, with a very large area and it’s the first national park inthe world. Wild animals in Yellowstone are under good protection. They do not live in cages like animals in most zoos. The park is large enough for animals to walk freely just like in the wild. They are able to live in a natural way. Many people have visited the park since it opened in 1872.Some animals in the park are not afraid of people. Sometimes people can get close to them easily. But people can’t hunt or feed animals in the park, because hunting or feeding will disturb animals’ life.Yellowstone National Park sets a good example of how people and wild animals live together peacefully. Putting animals in the cages is not a good way of protecting them. If people realize the importance of wild animals, they should give animals a comfortable living environment.Listen to the passage and fill in the blanks(听短文完成空格,每空格限填一词)【此处可播放相关音频,请去附件查看】20.

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank. Rhiannon Lambert, who treats about 180 clients a year with various kinds of eating disorders, says the number of those caused by “clean eating”disorders, says the number of those caused by “clean eating” (21) ______ (double) in the past (21) ______ (double) in the past three years. “They develop particular habits, or won’t eat food when walking, because they think that food can only be eaten when they (22) ______ (seat),think that food can only be eaten when they (22) ______ (seat),” she said.” she said.Clean eating is promoted by some food bloggers, who are increasingly thought by a number of medical experts to be having a bad influence on young people today today. . “Young people lose this and cannot afford the lifestyle needed to follow it,” Lambert said. Health bloggers (23)not have enough knowledge but offer dangerous advice. These people are now role models (24) ______ word will inspire young people. I have clients who think they have to be a strict vegetarian to be successful. The extreme form of this is known as orthorexia nervosa (健康食品强迫症).Ur Ursula Philpot, a dietitian at the British Dietetic Association, said, “It is difficult to blame sula Philpot, a dietitian at the British Dietetic Association, said, “It is difficult to blame them completely. If it weren’t the bloggers, then it could be (25) ______ else. Orthorexia affects more girls than boys, although boys are much more affected tha n girls.” Philpot said, “At the top of most people’s lists of bad foods includes gluten (麸质) and dairy. (26) ______ you talk to young people more, you will find some of them worry all day about eating a biscuit.”The condition starts out as an attempt (27) ______ (eat) more healthily, but those who experience it fully focus on food quality and purity. “There may be several reasons forsomeone to take up clean eating,” Philpot said. “Eating disorders are serious mental illnesses and their causes are complex. Research is telling us that they may be more biologically based than we thought, (28) ______ social and environmental factors also play a part in their development.”Deanne Jade, the founder of the National Centre for Eating Disorders, said, “A lot of y oung people don’t think they need treatment and there are too many messages in the media.

I don’t know what the solution is, but in many cases, gettin g people to recover from an eating disorder means (30) ______ (get) from an eating disorder means (30) ______ (get) them to relax their ideas about clean eating.”them to relax their ideas about clean eating.” Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.A. applyB. supposedC. accurateD. consumeE. existingF. maintain G . options H. nature I. sensitive J. address K. willingnessA recent troubling study showed that “fake news fake news”” spread significantly faster, deeper and more broadly than the truth, and the effect is even more remarkable when regarding news as opposed to reporting on natural disasters, finance or science. So how can we encourage individuals to seek 31online content? Leading scholars are trying hard to deal with this question.Processing new information requires a considerable mental effort, especially when that information seems to conflict with your 32 worldview. It takes the 33to admit you may be wrong. But with a great amount of conflicting information available, who ’s to say what what’’s actually true and what s actually true and what’’s false? If you can’can’t tell, t tell, why not just make life easy and go with what supports your current beliefs?So what 34 do we have? Many suggest that we can 35the issue by reforming adult behavior, but this is aiming too far from source. An alternative solution is using early education to help individuals recognize these problems and 36critical thinking to the information they deal with. Currently, there is a push in the US to include Internet information classes into primary and secondary school curriculums. The movement, which has received some support, aims to make fact-checking seem like second 37 to individuals at an early age.Primary and secondary school are 38to be supplying students with the skills they need to develop into productive and informed members of our society. As our society develops, the curriculum we are teaching our students needs to develop as well.The Internet is an amazing tool, but to use it most effectively we have to accept its benefits while also understanding the ways in which it makes us dangerously39 . If students are still learning the practices such as writing in school, shouldn ’t they be learning how to 40the Internet responsibly as well?III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.People hold different views on almost anything, mainly because of the culture we are familiar with or the education we have received. We live in a 41world where people are quick to point out the faults and imperfections of others, yet seem unaware of their own. Some misguided souls believe they have a duty to help you to be a better person by telling you what a failure you really are first and then offering suggestions as to how you can improve.So what is the possible solution to42 ? If you are the one forcing others to feel 43 themselves, STOP . Make a conscious decision rather than 44the negative aspect of a person’s performance or attitudes attitudes. . Y ou’ll offer helpful suggestions from the beginning. If I’m painting o beginning. If I’m painting our living room and ur living room and 45in doing so, I would like my husband to say to me, “This is a tough job. Can I offer a suggestion that might make it easier for you?” rather than have him point out what a 46painter I am and then tell me how I should be doing it.If you are on the 47end of criticism, the “OK” response is a perfect solution. When someone comments negatively on a task you are doing or a personality issue of yours, a(n) 48 response is to defend and attack. However, this approach is rarely effective as it puts both parties on the49 . . Instead, simply reply with “OK”. This brief Instead, simply reply with “OK”. This brief one-word response 50the other person’s comment without agreeing with it or feeling necessary to engage in a debate about it.It is important to remain emotionally attached to what the other person is saying, to listen without feeling, to be a(n) 51observer. In fact, there is much that one can learn from a 52review. You can ask yourself: Did I make a mistake? Could I have done better? Did I give 100% of myself to the task at hand? If so, how can I improve myself? As for chronic (习惯性的) criticizers: It is important to set strict boundary with them. Remove yourself from their 53when necessary.54 , one can learn to be “OK” with criticism and not allow it to negatively impact your life or relationship with the other party.

A. harm B. conflict C. obstacle D. truthSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢体). This makes coordinating (协调) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.Another interesting characteristic of bat flight is the way in which bats land-upside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.56. Which of the following is the topic of the passage?A. Places where flying animals choose to land.B. Why scientists have difficulty observing bats.C. Differences in the eating habits of bats and birds.D. Ways in which bats move differently from birds.57. Which of the following is a false assumption about bats that was recently corrected?A. They cannot hear any sound.B. They sleep upside down.C. They fly similarly to birds.D. They hide in tree branches.paragraph) probably refers to “______”.refers to “______”.The word ““it” (in 2nd paragraph) probably58. The wordA. the distance to the netsB. the sense of flying heightC. the flying directionD. the ability to change the speed59. According to the passage, which of the following is NOT true?A. Bats might hurt themselves when landing.B. Bats can hang upside down like birds.C. Bats can adjust speed before landing.D. Bats and birds land in different ways.(B)What is a TEDx event?TEDx brings the spirit of TED’smission of “ideas worth spreading” to localcommunities around the globe. A TEDx event is a local gathering where live TED-like talks and videos previously recorded at TED conferences are shared with a community. TEDx events are fully planned and coordinated independently, on a community-by-community basis. All TEDx events present multiple issues and a diversity of voices from many disciplines. After all, what’s the fun without a little variety?If you want to organize a TED x event, you’ll need to apply for a TEDx license. No one is qualified to organize an event without being granted a license by TED.So you want to organize a TEDx event?Before you start you should know the TEDx rules, which are non-negotiable and mandatory.General rules* We value and welcome young organizers, but if you’re under 18 years old, you must be supervised by an adult. TED doesn’t grant licenses to individuals associated with controversial or extremist organizations.* TED allocates one location-based license series per application. You must live in the city for which you are applying for a license. Your TEDx event must happen in the city forwhich you received the license.* Your event must maintain the spirit of TED itself: focused on the power of ideas to change attitudes or lives. Your event may not exceed (超过) one day in length.* Up to 100 individuals may attend your event. Only individuals who have attended an official TED conference may organize an event with more than 100 attendees. Having attended one or multiple TEDx events or TEDWomen does not qualify you to host an event for more than 100 guests.* TEDx events are named after locations, such as cities, neighborhoods, streets etc., and aim to serve that named community. Event names must comply with the guideline laid out in naming your event.Special attentions※ A TEDx event is not a platform for professional speakers, such as motivational speakers and professional life coaches. Its purpose is to give a platform to those who don’t often have one.※ A TEDx event cannot be used to raise money, not even for a charity.※ A TEDx event can’t be co-branded with an institution except under specific license types – for a college or university, or for internal events (for corporations and organizations).※ TEDx events may not be used to promote spiritual or religious beliefs, commercial products or any kind of political agenda.※ Every TEDx event either shows only TED Talk videos to its audience, or shows both TED Talk videos and live speakers from the community. For events less than half a day in length, two TED Talks videos are required to be shown. For longer events, 25% of the total number of talks must be official TED Talk videos.60. What do we know from the first part of the passage?A. TED organization is not responsible for TEDx events.B. TEDx is TED-like but it is operated independently.C. People can give TEDx speeches under no conditions.D. TEDx speeches should follow a single topic principle.61. According to the General rules, a TEDx event organizer should ______.A. extend the event to one dayB. hold a TED event firstC. name the event after locationsD. host the event in different cities62. Which of the following people may be allowed to make a TEDx speech?A. A member of a volunteer group who wants to collect money for the war victims.B. A college student who wants to advocate the use of green and renewable energy.C. A CEO in a high-tech industry who wants to popularize its newest product.D. A professional speaker who wants to motivate people with successful stories.(C)In an industry with low margins (利润) where the traditional wisdom is led by Walmart, the key to success is lowering operating costs. A big part of those costs are in labor, so it is no surprise that the retail industry has been a leader in using more part-time workers to keep labor costs down, holding the line on wages, not training, and with few exceptions, seeing employees as a cost to be minimized. There is no doubt that these businesses fight for every dollar of margin. Unlike trend-leading hi-tech companies which spend a lot of money on employees to get them innovated, retail industry can spend very limited money on theiremployees.What researchers found was that companies were often staffing their stores far too low, and that many stores tended to perform better with higher staffing levels and were more profitable. Let’s let that sink in for a minute. The stores were making more money (with all other things being equal) when they spent more on employees.They also found that retailers didn’t do a ver y good job when staffing levels are just the actual demand in those stores. In fact, they set staffing levels identically across stores, even when the needs of the stores varied considerably. The average store did not appear to be understaffed, but there were enough that were understaffed and effect on overall company profitability was substantial.Interestingly, the same researchers persuaded the retail chain to run an experiment withthem and slightly raise staffing levels to the amount that their analysis of historical data suggests would be ideal. Y es, labor costs obviously jumped when they did that, but so didcosts——the biggest part is the cost of the profits. In retail, labor is a small percentage of costsproducts they sell. So, the net effect was an increase in profits of $7.4 million across 168 stores on an annual basis.What can we learn from this? One question worth thinking of is: How can traditional retail industry survive the increasingly severe market? Especially now with the growth of online retail, the one thing stores still have going for them is one to one customer contact with salespeople. If retailers cut that down to almost nothing, then they have effectively eliminated their competitive advantage against online stores.63.

Although your major and coursework are relevant to landing a job, they are not the onlydeciding factors.College graduation eventually means taking much of your attention in your first job search. This process can be challenging, especially for those students who had thought very carefully about their chosen major and their potential career path—or those who majored in a field not directly connected to a specific career he eventually got. If you are in one of these groups, fear not! 67Some majors are tied directly to specific career fields. For example, if you wish to become a teacher, you will likely have needed to complete an education program and eventually sit for a licensing exam. The same applies to majors in nursing. If you did not complete an acceptable rsing program, you won’t be able to take the nursing licensing exam. 68 nu nursing program, you won’t be able to take the nursing licensing exam.Other majors, however, are closely related to career paths but don’t necessarily require a degree in the area. For example, students who majored in finance, math, or statistics may also have the necessary skills to be hired as an accountant.Hopefully, as a college student, you were able to do more than just attend classes and read your course books. Y our non-academic experiences can be very influential on your future career as well. Did you work during college, volunteer, or participate in a club or organization? 69 If you volunteered with a non-profit organization such as a homeless or domestic violence shelter, seek out positions in social services related to case management or victim advocacy. You may qualify for a position regardless of your major.Although it often seems like your college major alone determines your career fate, this just isn’t the case. 70 If you don’t know what career opti If you don’t know what career options to consider based on ons to consider based on your major, talk to your faculty or academic advisor. Y ou may be surprised at what opportunities await! IV . Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Are you working with your computer routinely either as a office employee or a game lover? Are your eyes dry, watery, blurry, seeing double or sensitive to light? If your answer is a a ““yes yes”, you ”, you ”, you are likely one of many people today who suffer from digital eyestrain, also called are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome. What on earth is this syndrome coming from? What can we do to deal with this problem?Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists attention during the day but can result in interrupted sleep patterns at night.Years of scientific researches indicate that eyestrain isn isn’’t necessarily an unavoidable problem for those who deal with computer work in the daily base. There are ways you can adopt which can overcome the problem considerably. To begin with, your computer screen should be high-resolution (高分辨率), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that “computer glasses”, which cut down glare and blue light ,are available.Besides, to reduce your risk for computer-vision syndrome, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, eyestrain are significantly reduced when computer workers take four additional five-computer workers take four additional five-minute “mini minute “mini minute “mini--breaks”breaks” throughout their workday. throughout their workday. Finally, many of us fall into bad habits while using digital screens, which only worsen the effects of eyestrain. While viewing digital screens, many people blink (眨眼) one third less often than they usually do. Place a reminder on your computer to “blink blink”” so that your eyes don eyes don’’t dry out.。
