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 readALike human beings, dogs may catch cold because of cold weather, wet conditions or can also get it from other sick dogs. If a dog has a running nose and watery eyes, coughs or sneezes (打喷嚏), then it is quite probable that the dog has caught cold.A dog's cold can get over after a few days without treatment but it totally depends upon the owner to treat it with medications or improve its immune power (免疫力)to get rid of the cold naturally. Following are some of the things you can do if your dog gets a cold.You can improve its immune power by giving it proper nutrient diet. Healthy food can really do wonders. Try to give it food which is either suggested by the vet (兽医) or is healthy for your pet. Increase the intake of food which is rich in vitamins A, C and E.Keep your dog warm. The best place for your dog in winter is inside your house. Do not keep your dog outside when it is cold and wet. At home you can also keep the dog warm with the help of carpets. This will make him comfortable and help him to recover fast.Increase the fluid (流质)intake as it helps a lot. Water can be the best choice but you can also add broth (肉汤)in water which will give your dog strength. Warm water will make your dog morecomfortable and will also keep the dog away from the respiratory infections (呼吸道感染). Steam treatment is considered to be effective in getting rid of cold. It makes the nasal (鼻的) passage wet, which helps proper breathing. Just fill your bathroom with steam and leave your dog inside the bathroom for 15 minutes. Do it nearly 2 to 3 times a day and you will see your dog recovering.These are some of the things you can do to help your dog recover from cold. However, if you are not able to find any improvement in its health, then turn to the vet for help immediately. Take your dog for regular checkups so as to avoid complications (并发症).56. From the first paragraph we know about ________.A. the difficulty in keeping a dog as a petB. characteristics of sick dogsC. the similarities between dogs and human beingsD. causes and symptoms (症状)of cold in dogs57. When your dog catches cold, you should feed it on ________.A. its favorite foodB. the suggested food by the vetC. some meat and waterD. food rich in vitamin B58. When a dog catches cold, it is wrong to ________.A. keep it inside during cold and wet weatherB. leave it inside the bathroom full of steamC. let it eat too much solid foodD. keep it sleeping on rugs at home59. It can be learnt from the text that ________.A. a dog’s cold can always disappear naturallyB. it’s quite easy to make a sick dog recover from coldC. treating a dog’s cold sometimes needs a vet's helpD. cold in dogs won’t spread between each other.BWant to find a job?

But that night when my dad tried to cheer me up, my laugh turned into crying.. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.Just as crying can be healthy, not crying--- holding back tears of anger, pain or suffering--- can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural --- and healthy --- emotional response (反应).63. Why didn't the author cry when her grandmother died?A. The author doesn’t give the explanation.B. Because she did not love her grandmother.C. Because she was too shy to cry at that time.D. Because her father did not allow her to feel too sad.64. It can be inferred from the text that ________.A. there are two ways to keep healthyB. crying does more good to health than laughingC. emotional health has close connection with physical healthD. crying and laughing play the same roles65. According to the author, which of the following statements is true?A. Crying is the best way to get help from others.B. Fighting back tears may cause some health problems.C. We will never know our deep feelings unless we cry.D. We must cry if we want to reduce pressure.66. What might be the most suitable title for the text?A. Power of TearsB. How to Keep HealthyC.

Fill in each blank with the word or phrase that best fits thecontext.The famous American inventor Thomas Alva Edison once claimed that geniuswas one percent inspiration and ninety-nine percent perspiration(汗水). Now, itseems, there is scientific evidence to __41__ his c laim. The idea that geniuses such as Shakespeare, M ozart, and Picasso possessed c ertain inborn talents is a false belief, according to a study by a British p sychologist and his colleagues.After examining outstanding performance in the arts and sports, these researchers concluded that __42__ is determined by opportunity, encouragement, training, motivation, self-confidence, and —most important of all —__43__. Even people who were not thought to be 44__ with any special talent could, after having received training, reach levels __45__ considered a ttainable (可获得的) only by gifted individuals. ‘Talent is a false belief, and it is time that people got rid of it,”they said.This theory — a dramatic __46__ with traditional beliefs — has been __47__ by academics worldwide. In fact, studies of accomplished artists and mathematicians, and top tennis players and swimmers, have reported few early signs of _48__ in these people before any parental encouragement. No case has been found of anyone reaching the highest levels of achievement without _49__ himself or herself to thousands of hours of serious training. Even those who are believed to be exceptionally talented —whether in music, mathematics, chess, or sports —have needed l engthy periods of instruction and practice to achieve their highest level of success. ‘The persistent false belief that some people reach high levels of performance without spending numerous hours practising __50__ much to the fact that their practice is usually outside the casual observer’s view,’ stated one scientist.The importance of practice has been noticed in athletics. For instance, differences in the composition of certain muscles were once thought to be __51_ predictors of athletic performance. However, the differences in the proportion of certain muscle fibers(组织) that are __52__ for success i n long-distance running are largely the result of extended practice in running.‘What makes a genius then?’ one may ask. __53__, there is no clear answer.

About 150 feet from shore, he spied an object moving downriver. “I thought it was a life jacket,” he says. “When I caught up to it, I realized it (25) _________ (attach) to a person.”Now in water up to his neck, Kevin grabbed the man, (26) _________was floating on his back unconscious, under both armpits and held his head above the surface. Kevin struck the man’s chest again and again. After five hits, the man coughed up water and began speaking incoherently. Just back to life, the man was still weak. Battling the current, Kevin sidestepped his way (27) _________the shoreline, repeatedly digging his shoes into the river’s rocky bottom. When he reached the bank, someone jumped into the river and helped Kevin lift the 200-pound drowning man over a six-foot brick retaining wall to waiting doctors, who took him away in an ambulance. The man recovered, but a friend who was boating with him died after being trapped underwater near the dam.Kevin pulled (28) _________up to sit on the shore beside Ryan, who had followed his father’s path down the river. “When I caught my breath, I realized I saved someone’s life, which is what I (29)_________do.” Kevin says.In December 2015, Kevin received an award from the Carnegie Hero Fund Commission. “Lots of honour-receivers lost their lives saving someone,” he says. “(30) _________ (put) in the same category is very humbling.”Section BDirections: Fill in each blank with a proper word chosen from the box.

Peter was eleven, Leigh-Ann nine, Laura six and Matthew only two. When Santa arrived, Mat thew parked himself on Santa’s lap and remained impressed greatly by him for the rest of the evening. Anyone who had their picture taken with Santa that Christmas also had their picture taken with little Matthew.Little did any of us know how precious those photos with Santa and Matthew would become. Five days after Christmas, our sweet little Matthew died in an accident. When our first Christmas without Matthew approached, it was hard for us to get into the holiday spirit.Then, on December 13, we were just finishing dinner when we heard a knock on the front door. When we went to answer it, no one was there. On the front porch was a card and gift. The gift-giver just wanted to help us get through a rough time by cheering us up with his or her name unknown, like a fairy.In the gift bag was a cassette of favorite Christmas music, which was in a little cardboard Christmas tree. We put the cassette in our player and, song by song, the spirit of Christmas began to warm ourhearts, and the thoughtfulness of our “fairy,touched our hearts.That was the beginning of a series of gifts from the clever giver, one for each day until Christmas. Each gift followed the theme of “The Twelve Days of Christmas” in a creative way. The kids especially liked “seven swans a-swimm ing,” which was a basket of swan-shaped soaps plus passes to the local swimming pool. “Eight maids a-milking” included eight bottles of chocolate milk in glass bottles with paper faces. Every day was something very special.The ingenuity and thoughtfulness shocked us as we enjoyed each surprise. We were so caught up in the excitement and curiosity of what would possibly come next, that our grief didn’t have much of a chance to rob us of the spirit of Christmas. What our fairy did was absolutely miraculous.We give thanks for our fairy who was, we finally realized, our very own Christmas angel. We never did find out who it was, although we have our guess. We actually prefer to keep it that way.56. The photos taken with little Mathew became valued becauseA. Mathew is the youngest child of our familyB. they are the photos taken on Christmas EveC.

Special diet.(C)I plan to remember this year’s vacation season with just two words: NEVER AGAIN. Never again, that is, will I take all my technology along. The Internet has ruined summer vacations.Instead of reading dog-eared summerhouse mystery novels, this year we browsed the Internet. Instead of long evenings of crossword puzzles or board games, we checked our Twitter feeds andupdated our Facebook pages. And that, of course, is the problem with the Internet: It,s so easy that,unless you’re equipped with massive self-control, you use it if it’s there.For several years, I kept my Internet addiction under control by using inconvenient technology: a laptop which is old and not in good condition and a slow dial-up connection. But this year, the combination of a new iPad and very good Wi-Fi turned out to be fatal. The magical iPad signaled silently from the picnic table: What harm could it be to give the e-mail a quick check? But once that attractive touch screen lights up, who can resist?I’m not the first to get lost across this problem, of course. I,m a late adopter. As early as 2008,Nicholas Carr, author of The Shallows: What the Internet Is Doing to Our Brains, was warning that broadband Internet was reducing our attention spans and making us stupid. The Web, he said,encourages us to get stuck into our “natural state of distractedness.” Even before that, in 2000,Harvard’s Robert Putnam warned that television 一 and, more broadly, staring into any kind of screen — had reduced the amount of time families spent in social interactions. And last year, researchers at UC-Irvine reported that employees who were unplugged from their e-mail got more work done 一 andexperienced far less stress.Access to the Web is unquestionably a wonderful thing. I love having a bottomless library at my fingertips; I love having the world’s newspapers on my electronic doorstep. I love being able to pay bills and make airplane reservations online. And, thanks to those ugly cell phone towers in the woods, we now have a way to call f or help if we need an ambulance or a fire truck. It’s also nice to have an app thatidentifies the constellations (星座)when you hold the iPad up to the night sky. But then, you have toremember to put the screen down and simply drink in the stars — the original, uncut version.And that’s the point: It’s important not to let the convenience of the Internet get in the way of simpler beauties. It,s our fault instead of the Internet, for failing to control the urge to browse. Myproblem is learning how to limit the time I spend on it. So now I have one more thing to look forward to next summer: More time reading old novels; more time playing crossword puzzles and chasing frogs. Next year, I promise to unplug. Except, of course, when we need to find a new bike trail, or Google a recipe for wild blueberry pie.63. Throughout the passage, what evidence does the author provide to support the claims he makes in paragraph 2?A. Scientific studies and statistics about Internet use.B. Historical facts regarding the effects of television and the Internet.C. Personal accounts and opinions of those who have studied the Internet.D. Results of opinion polls about Internet use.64. According to the passage, how does the writer keep himself from getting addicted to the Internet?A. By using outdated laptops with poor Internet access.B. By only giving the e-mail a quick look.C. By keeping the electronic devices out of reach.D. By accessing new iPad and good Wi-Fi.65. In the article, UC-Irvine research functions as .A. a personal account that illustrates an idea about social lifeB. a restatement of the author’s main argumentC. historical context to allow the reader to understand the article’s settingD. evidence to support a point made by Nicolas Carr66. Which of the following statement will the author probably agree to?A. people should not rely simply on the Internet to provide them with news and other informationB. people can have meaningful vacations only if they leave all electronic devices at homeC. although the Internet is often useful, it can become addictive and prevent human interactionD. even though there are some good things about the Internet, overall it has affected civilization for the worseSection CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A. Watling Street’s origins are lost in prehistory.B. But Shakespeare can still be connected to the road.C. In fact, it is hard to find a character from the British imagination who cannot be linked toWatling Street in some way.D. It is one of the few permanent fixtures of this island and one of the first lines on the map.E. Here characters including Sherlock Holmes and Batman have been brought to life.F. It is Watling Street — and there is no road in the English-speaking world more steeped instories.The road that led to 1,000 storiesIn his new book Watling Street, John Higgs explores one of Britain’s oldest roads — and how it inspired countless stories, from the Canterbury Tales to Great Expectations to Star Wars.Chaucer’s Canterbury Tales, written in the late 14th Century, tells the story of a group of medieval pi lgrims travelling from London to Canterbury. Six hundred years later, the Star Wars movies were filmed on the same road.67 .We now think of Watling Street as the A2 and the A5 motorways, which run across Britain from Anglesey in north-west Wales to Dover in south-east England in a way that joins two opposite sides at an angle. But the road has existed throughout all of British history. 68 . It has been a Neolithic (新石器时代的)pathway, a Roman road, one of the four medieval (中世纪的)royal highways, a main road in the age of coach travel and a road today usually withtraffic jams.It is a place that reflects its own history, always being rewritten. 69 . James Bond drives along the road in Ian Fleming’s novel Moonraker. Doctor Who appears suddenly a t different points along it in different historical eras. It is part of Robin Hood’s plans in the medieval narrative poem A Little Geste of Robin Hood and his Meiny. Miss Havisham’s decaying Gothic house in Charles Dickens’ Great Expectations is based on R estoration House in Rochester, which stands just yards from Watling Street. In the 12th-Century Histories of the Kings of Britain, Geoffrey of Monmouth tells how a young Merlin released the dragons that caused King V ortigem’s tower to fall. This was at Dinas Emrys in Snowdonia, on the route of the original, pre-Roman road through Wales.For many years it was believed that William Shakespeare wrote a play called The Widow of Watling Street', it was included in early collections of his work. It is now thought that the real author of that play was Thomas Middleton.70 .Before the Romans bridged the Thames, the original route of Watling Street crossed the river where Westminster Palace now stands. The route would have run close to where Shakespeare’s Glob e Theatre in Southwark later stood.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.Reading the world in 195 boobsIn 2012, I set myself the challenge of trying to read a book from every country of all 195 UN- recognized states in a year. With no idea how to find publications, I decided to ask the planet’s readers for help. I created a blog called A Year of Reading the World and put out an appeal for suggestions of titles that I could read in English.The response was amazing. Before I knew it, people all over the planet were getting in touch with ideas and offers of help. Some posted me books. Others did hours of research on my behalf. In addition, several writers, like Turkmenistan’s Ak Welsapar and Panama’s Juan David Morgan, sent me unpublished translations of their novels. Even with such an extraordinary team behind me, however, sourcing books was no easy task.But th e effort was worth it. As I made my way through the planet’s literary landscapes, extraordinary things started to happen. Far from simply armchair travelling, I found I was inhabiting the mental space of the storytellers. I discovered, book packing offered something that a physical traveller could hope to experience only rarely: it took me inside the thoughts of individuals living far away and showed me the world through their eyes. More powerful than a thousand news reports, these stories not only opened my mind to basic information of life in other places, but opened my heart to the way people there might feel. And that in turn changed my thinking. Through reading the stories shared with me by bookish strangers around the globe, I realized I was not an isolated person, but part of a network that stretched all over the planet.One by one, the country names on the list that had begun as an intellectual exercise transformedinto places filled with laughter, love, anger, hope and fear. Lands that had once seemed foreign and remote became close and familiar to me — places I could identify with. At its best, I learned, fiction makes the world real.V.

The 2-Minute Rule ____32_____ procrastination and laziness by making it so easy to start taking action that you can’t say no. It might sound like this strategy is too basic for your ____33_____ life goals, but I beg to differ. It works for any goal because of one simple reason: the_____34____of real life.As Sir Isaac Newton taught us a long time ago, objects at rest tend to stay at rest and objects in motion tend to stay in motion. This is just as true for humans as it is for falling apples. Once you start doing something, it,s easier to ___35______ doing it. I love the 2-Minute Rule because it takes up the idea that all sorts of good things happen once you get started.The most important part of any new habit is getting started — not just the first time, but each time. It’s not about performance, it’s about ____36_____ taking action. In many ways, getting started is more important than succeeding. This is ____37_____ true in- the beginning because there will be plenty of time to improve your performance later on. The 2-Minute Rule isn’t about the results you achieve, but rather about the _____38____ of actually doing the work. I can,t guarantee whether or not the 2-Minute Rule will work for you. But, I can guarantee that it will never work if you never try it.The problem with most articles you read, podcasts you listen to, or videos you watch is that you ____39_____ the information but never put it into practice. I want this article to be different.I want you to actually use this information, right now. What’s something you can do that will take you less than two minutes? Do it right now. Anyone can ____40_____ the next 120 seconds. Use this time to get one thing done.Go.III.

How much of my own country had I really seen and experienced? To those from a place as vast and varied as China, Britain was really so ___48___in comparison and so to have spent 20 years there and not seen every part of it was quite surprising.I had a conversation with a Chinese colleague over the reasoning behind our use of golden Cotswold stone, which sounds dull for most people. As a student of history, I found anything___49____fascinating. However it was not the stone within British cities I found interesting. What was curious was that it was something I had never even considered, and yet here was someone___50____on something I had simply taken for granted.We continued our discussion, yet I was left___51___that I could not answer her question. In China, as well as a wealth of new culture that fascinated me, I discovered that there were parts of the UK’s culture, history, the very structure of my identity that were so different, so unique from China that I also___52____a newly found interest in my own heritage.In this respect, travelling enables you with two things. Firstly you develop a(n) ___53___with new cultures, understanding customs, experiencing cuisines and absorbing the sights and smells ofevery new city.

Special diet.(C)I plan to remember this year’s vacation season with just two words: NEVER AGAIN. Never again, that is, will I take all my technology along. The Internet has ruined summer vacations.Instead of reading dog-eared summerhouse mystery novels, this year we browsed the Internet. Instead of long evenings of crossword puzzles or board games, we checked our Twitter feeds and updated our Facebook pages. And that, of course, is the problem with the Internet: It,s so easy that, unless you’re equipped with massive self-control, you use it if it’s there.For several years, I kept my Internet addiction under control by using inconvenient technology: a laptop which is old and not in good condition and a slow dial-up connection. But this year, the combination of a new iPad and very good Wi-Fi turned out to be fatal. The magical iPad signaled silently from the picnic table: What harm could it be to give the e-mail a quick check? But once that attractive touch screen lights up, who can resist?I’m not the first to get lost across this problem, of course. I,m a late adopter. As early as 2008, Nicholas Carr, author of The Shallows: What the Internet Is Doing to Our Brains, was warning that broadband Internet was reducing our attention spans and making us stupid. The Web, he said, encourages us to get stuck into our “natural state of distractedness.” Even before that, in 2000,Harvard’s Robert Putnam warned that television 一and, more broadly, staring into any kind of screen —had reduced the amount of time families spent in social interactions. And last year, researchers at UC-Irvine reported that employees who were unplugged from their e-mail got more work done 一and experienced far less stress.Access to the Web is unquestionably a wonderful thing. I love having a bottomless library at my fingertips; I love having the world’s newspapers on my electronic doorstep. I love being able to pay bills and make airplane reservations online. And, thanks to those ugly cell phone towers in the woods, we now have a way to call for help if we need an ambulance or a fire truck. It’s also nice to have an app that identifies the constellations (星座)when you hold the iPad up to the night sky. But then, you have to remember to put the screen down and simply drink in the stars — the original, uncut version.And that’s the point: It’s important not to let the convenience of the Internet get in the way of simpler beauties. It,s our fault instead of the Internet, for failing to control the urge to browse. My problem is learning how to limit the time I spend on it. So now I have one more thing to look forward to next summer: More time reading old novels; more time playing crossword puzzles and chasing frogs. Next year, I promise to unplug. Except, of course, when we need to find a new bike trail, or Google a recipe for wild blueberry pie.63. Throughout the passage, what evidence does the author provide to support the claims he makes in paragraph 2?A. Scientific studies and statistics about Internet use.B. Historical facts regarding the effects of television and the Internet.C. Personal accounts and opinions of those who have studied the Internet.D. Results of opinion polls about Internet use.64. According to the passage, how does the writer keep himself from getting addicted to the Internet?A. By using outdated laptops with poor Internet access.B. By only giving the e-mail a quick look.C. By keeping the electronic devices out of reach.D. By accessing new iPad and good Wi-Fi.65. In the article, UC-Irvine research functions as .A. a personal account that illustrates an idea about social lifeB. a restatement of the author’s main argumentC. historical context to allow the reader to understand the article’s settingD. evidence to support a point made by Nicolas Carr66. Which of the following statement will the author probably agree to?A. people should not rely simply on the Internet to provide them with news and other informationB. people can have meaningful vacations only if they leave all electronic devices at homeC. although the Internet is often useful, it can become addictive and prevent human interactionD. even though there are some good things about the Internet, overall it has affected civilization for the worseSection CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.The road that led to 1,000 storiesIn his new boo k Watling Street, John Higgs explores one of Britain’s oldest roads — and how it inspired countless stories, from the Canterbury Tales to Great Expectations to Star Wars.Chaucer’s Canterbury Tales, written in the late 14th Century, tells the story of a gr oup of medieval pilgrims travelling from London to Canterbury. Six hundred years later, the Star Wars movies were filmed on the same road. 67 .We now think of Watling Street as the A2 and the A5 motorways, which run across Britain from Anglesey in north-west Wales to Dover in south-east England in a way that joins two opposite sides at an angle. But the road has existed throughout all of British history. 68 . It has been a Neolithic (新石器时代的)pathway, a Roman road, one of the four medieval (中世纪的)royal highways, a main road in the age of coach travel and a road today usually with traffic jams.It is a place that reflects its own history, always being rewritten. 69 . James Bond drives along the road in Ian Fleming’s novel Moonraker. Doctor Who appears suddenly at different points along it in different historical eras. It is part of Robin Hood’s plans in the medieval narrative poem A Little Geste of Robin Hood and his Meiny. Miss Havisham’s decaying Gothic house in Charles Dickens’ Great Expectat ions is based on Restoration House in Rochester, which stands just yards from Watling Street. In the 12th-Century Histories of the Kings of Britain, Geoffrey of Monmouth tells how a young Merlin released the dragons that caused King V ortigem’s tower to fal l. This was at Dinas Emrys in Snowdonia, on the route of the original, pre-Roman road through Wales.For many years it was believed that William Shakespeare wrote a play called The Widow of Watling Street', it was included in early collections of his work. It is now thought that the real author of that play was Thomas Middleton. 70 .Before the Romans bridged the Thames, the original route of Watling Street crossed the river where Westminster Palace now stands. The route would have run close to where Sha kespeare’s Globe Theatre in Southwark later stood.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.Reading the world in 195 boobsIn 2012, I set myself the challenge of trying to read a book from every country of all 195 UN- recognized states in a year. With no idea how to find publications, I decided to ask the planet’s readers for help. I created a blog called A Year of Reading the World and put out an appeal for suggestions of titles that I could read in English.The response was amazing. Before I knew it, people all over the planet were getting in touch with ideas and offers of help. Some posted me books. Others did hours of research on my behalf. In addition, several writers, like Turkmenistan’s Ak Welsapar and Panama’s Juan David Morgan, sent me unpublished translations of their novels. Even with such an extraordinary team behind me, however, sourcing books was no easy task.But the effort was worth it. As I made my way through the planet’s literary landscapes, extraordinary things started to happen. Far from simply armchair travelling, I found I was inhabiting the mental space of the storytellers. I discovered, book packing offered something that a physical traveller could hope to experience only rarely: it took me inside the thoughts of individuals living far away and showed me the world through their eyes. More powerful than a thousand news reports, these stories not only opened my mind to basic information of life in other places, but opened my heart to the way people there might feel. And that in turn changed my thinking. Through reading the stories shared with me by bookish strangers around the globe, I realized I was not an isolated person, but part of a network that stretched all over the planet.One by one, the country names on the list that had begun as an intellectual exercise transformed into places filled with laughter, love, anger, hope and fear. Lands that had once seemed foreign and remote became close and familiar to me — places I could identify with. At its best, I learned, fiction makes the world real.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72.这位专家应对变化的能力令人赞不绝口。

Everything happens for a reason.(23)__________ mistakes and failure, you would never have learned. Without pain, you would never have grown. Once you understand this,you will know that everything comes in (24)__________( serve )a purpose. So don't stress or think that life is unfair, because everything happens for a reason. And only time will tell what it will teach us.2. Focus on one thing at a time. You can have it all but not all at once.(25)__________ is not surprising that many of us are doing too many things at once. We need to make ends meet. But if you are working three jobs at a time, it is not likely that you will succeed at any of them. You have to keep your eyes on the big picture. You have to ask yourself what exactly do you want to achieve for the next 10 years? Focus on one thing at a time. Achieve your goals one by one.3. Y ou can plan ahead, but your plan will definitely change when the time comes.You can plan ahead because sometimes planning ahead can give you a clearer direction of(26)__________ you want to go. However, plans will almost always change, so be prepared!4. Trust your instincts.Don't worry too much about a decision you (27)__________ __________ make. Just do what feels right.

Each word can onlybe used once.Note that there is one word more than you need.A. aggressiveB. slightlyC. psychologicalD. shelterE. withdrawnF. sufferedG. subjectedH. copingI. judgingJ. surprisingK. fatesthey are affected, suggests a new study. And, _____31_____, it is not the youngest kids who are hurt the most in the long term.Bullying can have long-lasting effects, but particularly when it begins in adolescence, the researchers say. People _____32_____ to either verbal ( 口头上的)or physical bullying are known to be at greater risk of developing depression, anxiety disorders or to behave violently. But not everyone reacts in this way.Children bullied for the first time before they hit adolescence seem to get over it, but those who are bullied for the first time later on in adolescence seem to become more ____33______or are more likely to turn to drink as a means of _____34_____. These are the conclusions of psychologist Matthew Newman and colleagues from the University of Texas at Austin, US.The team gave questionnaires to nearly 1,500 college students regarding their experience of physical and ____35______ bullying before adolescence—before high school—and in late adolescence—at high school. They assessed mood and mental state, ___36______ by signs of anxiety or depression, such as sleeplessness. The group was also questioned about how they would react to certain challenges, such as humiliation.People who were bullied all revealed ____37______higher levels of stress. But while those bullied earlier in life seemed to respond normally to provocation (挑衅),people bullied for thefirst time late in adolescence are more _____38_____and sensitive to violence.There are also sex differences between those bullied for the first time during adolescence, with females more likely to react aggressively when provoked and males are much more likely to turn to alcohol to escape bad situations.The best solution in all cases was strong social support, whether from friends, family or school. Those with no one to share their problems with____39______ the most.So perhaps it is best not to ____40______ children completely from bullying early on, suggests Newman. “They may get stressed,,but unhealthy coping really jumps out when they are bullied for the first time later on. “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.Whether or not you believe Professor Stephen Hawking’s alarming theory that building a “strong” artificial intelligence (AI) could lead to the end of the human race, it’s clear that AI is reaching the point where soon it will affect almost every aspect of how we work with computers. We must get used to computers that ______41____ back.Last year, investment bank Deep Ventures attracted much media attention when it announced that it had _____42_____ an AI computer to its board of directors to help make important business decisions. What ______43____ happened was that the company used a program called VITAL to_____44_____ potential investments (授资) in different businesses. But VITAL doesn't attend board meetings or vote - it's just a ____45______. While it's not quite the evil robot we see in science fiction movies, it shows us how far computers and AI have _____46_____.Soon AI systems will be driving our vehicles, _____47_____ our facial expressions as we perform complex tasks, translating our voices into different languages and building other machines for us in factories around the world. But they won't look like us or pretend to be ____48______.In the new film Ex Machina, a computer scientist is asked to _____49_____ whether a beautiful human-looking robot called Ava has human intelligence. I won't ____50______the film for you, but it occurred to me that one of the reasons we believe other human beings are conscious and have intelligence is that we're told they are______51____. Indeed, if you stopped believing other people have _____52_____, you would quickly find yourself unable to function in the world.Google's Eric Schmidt argues that we shouldn't worry about AI, and that we need _____53_____ to redesign our education systems so that we learn how to get on with the machines. As powerful computer-based intelligences continue developing, we must _____54_____the belief that only humans have intelligence and consciousness. Just as we have accepted the reality that the self-awareness that makes minds possible exists within the animal world, we may soon accept that it can also exist within the_____55_____ world.41.

A. human B. unknown C. foreign D. machineSection BDirections: Read the following three passages. Each passage is followed by 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)Yes, I admit it. I’m a true, incurable book abuser(施虐人). I like to fold dog ears. I like to break my books open so that their backs crack.I had a friend, who loved rubbing all the pages. I have another friend who is the exact opposite. She needs to keep her books completely new. I understand her. But once I get to know the book, I can’t help but show it some tough love. Because, believe me, although it sounds like I’m an abuser without a heart, that’s what it’s all about. Not hidden aggressions, or a lack of respect; not at all. Let me explain.I have one book by my favorite author Diana Gabaldon that looks like rubbish. It’s completely wrinkled up from rain, and on its way to falling apart. I brought it like that to have her sign it. I hope she’s realized what an honor it is to her as a writer. It means, basically, that I’ve read the book to bits. I wouldn’t bother to mistreat books that don’t mean anything to me. Only the best books get read well, carried everywhere, worth intense reading where I’m so caught up with words that I will spill coffee over it.For my further defense, I would like to call in a witness. I have a cook book. Like almost all my other cook books, it’s worn, and there are dirty marks of food in it. The book is called Tex-Mex—Food, Music and the Joy of Life from Texas. Just as the title suggests, this is more than a cook book.These are the words on the very first page:Tex-Max hasn’t been trendy for over 30 years. Considering it’s anything but cheap in calories, it probablynever will be, either. Tacos(墨西哥卷) are instead all about such an untrendy things as a love for life. It’s something you enjoy while spending time with your loved ones. …We hope, therefore, that this cook book will soon be as dirty as a really old and used cook book should be.Oh, how true! How wonderfully put! And it’s the same thing for books: whether you’re a book preserver or a book abuser, the approach is based on love and a joy for life. Because I believe all who are passionate about books, are passionate people.56. According to the passage, the writer often does the following to his book except______.A. have it dog-earedB. carry it everywhereC. keep it tidyD. have dirty marks in it57. Why does the writer treat his favorite books badly?A. To cover up his disrespect for its author.B. To conceal his aggressions to things around.C. To express his objection to the book preserver.D. To show his strong affection for the book.58. The book Tex-Mex—Food, Music and the Joy of Life from Texas is mentioned by the writer to show that__________________.A. it is really common to have dirty marks in the cook bookB. Tex-Max is not popular mainly because it’s low in caloriesC. the writer is not alone with the view that books should be abusedD. one must try some food like Tex-Max to experience the love for life59. What’s the main idea of the passage?A. The defense of one who treats books badly.B. The reasons why a certain book is preferred.C. The book lovers’ different habits of reading.D. The different ways to treat different books.( B)About PISAThe Program for International Student Assessment (PISA) is a triennial(每三年一次的) international survey which aims to evaluate education systems worldwide by testing the skills and knowledge of 15-year-old students. To date, students representing more than 70 economies have participated in the assessment.What makes PISA differentPISA is unique because it develops tests which are not directly linked to the school curriculum. The tests are designed to assess to what extent students at the end of compulsory education, can apply their knowledge to real-life situations and be equipped for full participation in society. The information collected through background questionnaires also provides context which can help analysts interpret the results.What the assessment involvesSince the year 2000, every three years, fifteen-year-old students from randomly selected schools worldwide take tests in the key subjects: reading, mathematics and science, with a focus on one subject in each year of assessment. The students take a test that lasts 2 hours. The tests are a mixture of open-ended and multiple-choice questions that are organized in groups based on a passage setting out a real-life situation. A total of about 390 minutes of test items are covered. Students take different combinations of different tests.Additional PISA initiativesPISA-based Test for Schools(PTS)As interest in PISA has grown, school and local educators have been wanting to know how their individual schools compare with students and schools in education systems worldwide.

PISA provides evaluation of education system within a certain country.( C)The Oxford dictionary has announced its word of the year. It’s spelled ... Actually,it isn’t spelled at all, because it contains no letters, just a “face with tears of joy” emoji.“The fact that English alone is proving not enough to meet the needs of 21st-century digital communication is a huge change,” says Caspar Grathwohl, president ofOxford Dictionaries. When one of his dictionary colleagues suggested using an emojiinstead of the word “emoji”, “lightbulbs went off”. Until recently, Grathwohl, who is44, avoided using emojis altogether because he worried that he would look as if he “was trying to get in on teen culture”. “I felt inauthentic. But I think there was a tipping point this year. It’s now moved into the mainstream.”Some 76% of the UK adult population owns a smartphone, and of those, between 80% and 90% use emojis. Worldwide, six billion are sent daily. The “face with tears of joy” is the most used, representing 20% of all UK and 17% of all US emoji use. It has overtaken the standard smiley-face emoji in popularity, which may mean that emoji users are moving towards exaggeration or irony or fun, or that all this emoji use has brought everyone to a higher emotional plane. Even if you don’t send emojis yourself, you will probably receive them.How far do emojis function as a language? “There’s a lot of prejudice against emojis,” Vyvyan Evans, a professor in linguistics at Bangor University, says. “A lot of people think they are a backward step, but this misunderstands the nature of human communication.” The picture is more complicated, with emojis offering both greater freedom and limitations than verbal language. “Emoji isn’t a language as such. They don’t develop in the way that the natural language does. But they are working according to the same principles of communication as the spoken language. What is the value of an emoji? I think I can prove this with an ordinary sentence.” There is a pause. “I love you,” he says. “Crikey(哎呀), I love you.” He says it again. The first time I think he means it; the second time we both know he doesn’t. “The meaning is coming from extra-language factors,” he says. “Emojis are performing the same function in digital speech.”Like any sort-of language, emoji is evolving. “I do think they are subtle(微妙) and rich,” Grathwohl says.“They can mean different things to different people. The fact that we are using emoji in combination to express more complex ideas and experiences is one of the most fun and playful parts of the whole words. Will emoji finally come to look something more like traditional language that we understand?” he asks. “That would be interesting.”63. The sentence “lightbulbs went off” (Para 2) means that ______________.A. the president became embarrassed and annoyedB. the president suddenly realized he was outdatedC. the suggestion was immediately adoptedD. the suggestion started a heated discussion64. The “face with tears of joy” is more popular than smiley-face emoji, which means that _______________.A. emoji is changing constantlyB. smiley-face emoji is too traditionalC. adults have more sorrow than joy in their daily lifeD. people like to express their emotions in a richer way65. Vyvyan Evans uses the sentence “I love you” as an example (Para 4) to prove that _____.A. emoji can express the real meaning behind wordsB. emoji is different from the natural languageC. people feel free to use emoji in communicationD. emoji will limit people in expressing their feelings66. Which of the following statement might Grathwohl agree with?A. emoji is too childish for adultsB. people have the same explanation for an emojiC. using emoji can add fun to communicationD. emoji won’t develop into a languageSection CDirections:Read the passage carefully. Fill in each blank with a proper sentence given in the box. Each sentenceHow did the largest of all dinosaurs evolve necks longer than any other creature that has ever lived? One secret: mostly hollow neck bones, researchers say.The largest creatures to ever walk the Earth were the long-necked, sauropods(蜥脚类恐龙). These vegetarians had the longest necks of any known animal.___________67______________. Their necks were six times longer than that of the current world-recorder holder, the giraffe.“They were really oversized,” said researcher Michael Taylor. “We’re used to thinking of elephants as big, but sauropods reached 10 times the size elephants do. They were the size of walking whales.”_________68__________, scientists studied sauropod’s body structure and analyzed other long-necked creatures such as giraffes and ostriches. In their study, Taylor and his colleagues found that the neck bones of sauropods possessed a number of characteristics that supported such long necks. For instance, air often made up 60 percent of these animals’ necks, with some as light as birds’ bones, making it easier to support long chains of thebones.Sauropods also had plenty of neck vertebrae, up to 19. __________69______. And sauropods had small, light heads that were easy to support.Furthermore, sauropods and other dinosaurs probably could breathe like birds, drawing fresh air through their lungs continuously. Instead, mammals have to breathe out before breathing in to fill their lungs with fresh air ________70______.IV Summary WritingDirection: Read the following passage. Summarize the main idea and the main file of the passage in no more than 60 words. Use your own words as far as possible.Energy independence. It has a nice ring to it. Doesn't it? If you think so, you're not alone, because energy independence has been the dream of American president for decades, What is it we want independence from, exactly? Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流)of biofuel available, and more may become available, but most biofuels cause economic waste and environmental destruction.Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.V.
