But when she became a mother and started hanging out with other parents,she didn't bring it up,even when the conversation turned to flying.It would have_____31_____the mood.Then in April2018,her home country of Sweden_____32_____a tax on aviation(飞行).The climate impacts of flying were on the evening news and the mood changed. Rosen_____33_____the moment.With her neighbor Lotta Hammar,she launched a campaign called"We stay on the ground",which has_____34_____10,000people to commit to avoid flights in2019.Kudos.But here's the_____35_____truth:in the grand scheme of things,barely anyone will follow suit.The_____36_____classes tend to have a lot to say about the eco benefits of avoiding meat,cycling and eating locally sourced food.But that_____37_____generally disappears when it comes to flying.We can't rely on international___38_____to stop aviation emission either.Yes,the UN has fixed up a deal to cap aviation emissions beyond2020.But it lacks real bite,allowing airlines to continue emitting carbon provided they offset(抵消)it.All this means we could really do with green tech riding to the rescue.Here,at least,there is a little good news.Even rather simple measures like freeing planes to fly in straighter lines could_____39_____cut carbon emissions.Hybrid(混合动力的)electric aircraft are also the

looking for a New Year's resolution,you might want to think about joining those 105000Swedes.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.In summarising the state of the planet—rising population,widespread conflict,one-sixth of the planet suffering extreme poverty and hunger,global warming一Jeffrey Sachs,author of"The Common Wealth、can paint a terrible picture.However,he's an_____41_____and believes that all of these problems can be overcome in relatively straightforward ways and at relatively little cost.That's because the root causes are interconnected and_____42_____ man-made.Take child morality(死亡).Perhaps surprisingly,the higher the child morality rate is,the higher the birth rate.This leads to a_____43_____population which puts a greater stress on already scarce resources,so farmers have to work harder to produce enough food for all, which means children are often put to work in the fields or at home.This,_____44_____, stops children getting the education which will allow them to learn,among other things,about better farming techniques to increase crop yields and provide more food to eat and sell.Sachs argues that the_____45_____of providing every child in poverty with an anti-mosquito bed net is a major first step.Malaria(疟疾)is a huge cause of death in children and the bed nets massively_____46_____infections.The fewer children that die of malaria,the more secure parents feel about their children surviving.The more secure parents feel,the fewer children they have,and so on,revising the_____47__trend just described.However,it is_____48_____a combination of measures at the same time that truly makes a difference:free school meals improve school attendance and health;supplying fertilisers to improve soil and better seeds provides even better harvests;basic health care and clean water supplies_____49_____more fatal diseases.These ideas are already being_____50_____implemented in over100African villages in underdeveloped regions.The cost of the proj ect is just$10per person per year,of which 50%comes from donors and the rest from a mixture of local and national governments and the villagers themselves.So if it's so_____51_____,why hasn't it been done before?What about all the aid that has been given to Africa and the underdeveloped countries of the world?Has it been lost to corruption(腐败)?Sachs argues that the real problem is not corruption,but the fact that rich governments have_____52_____such a lot,but actually given so little.They agreed to give 0.7%of national income in aid,but only five countries have met that_____53_____.He suggests current aid is$24billion per year,which translates as just ten dollars per person—not nearly enough to implement the_____54_____measures.So while Sachs sees an opportunity to end poverty forever,he also raises an _____55_____that this could be the last chance we have,'The longer we wait,the greater is the suffering and the larger the long-term costs?41.A.economist B.optimist C.expert

D.target54.A.restricted B.standardized C.requested bined55.A.alarm B.objection C.amount D.instanceSection 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)I'm in Marrakech,the heart of Morocco at the base of the Atlas Mountains,with my son, Sam.He's eight.We've come here with Mohamed,a friend who owns a store in our New York neighborhood.We're regular customers at Mohamed's store,where Sam can often be found negotiating with his friend.When they're not bargaining,they're chatting about swords,or camels,or the desert."You need to come to Marrakech,"Mohamed told me.I'll show you around and teach Sam how to really get a bargain!”So here we are.We meet up with Mohamed over a cup of tea at a table outside the tiny Cafe ben Youssef, deep in the old city of Marrakech.We're sitting in an area bordering the stalls of the marketplace.Vendors(小贩)with carts offer freshly squeezed orange juice,others sell dates or figs.Nearby are the workshops that supply the goods to this world-famous market.Later,as we walk around,Mohamed begins the first of his bargaining tutorials for Sam. "Everything in Morocco is open negotiation,Sam.When you hear a price,the first thing you say is'Too much一bezqf and then walk away.""But what if I like it?"“When you see something you like,maybe a lamp,you ask about something else instead. Then,as you walk out,you ask,"And how much is that lamp?9as though you5d just noticed it and aren't really that interested in it."We turn a comer and are greeted with sweet-smelling orange blossoms."Don't always give an offer.Make them continue to lower the price.Oh,and wear something Moroccan:Mohamed continues,as we enter a fairly large shop.Most of the stalls in Marrakech specialize in one thing,but not this one.Decorative and lethal-looking swords hang beside soft hand-dyed fabrics;large camel bones covered in writing sit beside massive copper lamps. It is here that Sam spots a box.“Look,a treasure chest!”It's made of wood,and painted red and gold.He opens the lid,then closes it.“Cool."Then he spots a tall,cobalt blue,tear-shapedold perfume bottle."Four hundred dirham,”the shopkeeper pronounces.Fifty dollars.Sam says nothing.Whether he's too shy or is practicing Mohamed's bargaining technique,I can't tell.He eventually agrees to pay200dirham,about$24.rd say the bottle is worth$10,at most. Clearly,his negotiating skills need a little work."Just to get started,Dad,”Sam measures me as he pays for the bottle.56.According to Mohamed,people in Marrakech like__________.A.bargainingB.tradingC.drinking teaD.showing friends around57.What does Mohamed advise Sam to do when he finds something he likes?A.To look for something similar in another shop.B.To complain to the vendor about its high price.C.To conceal his real preference from the vendor.D.To ask the vendor about the price as soon as possible.58.What does the writer imply about Sam's first negotiating experience?A.It is far from successful.B.It costs Sam more than the money he pays.C.It reveals Sam's potential in negotiation.D.It shows that Sam is too shy for negotiation.59.Which of the following might be the best title of the passage?A.A Shopping Trip.B.The Charm of the MarketC.A Busy City.D.The Art of the Deal(B)The Man Who Ate his Boots is a fascinating account of expeditions that went wrong.The book examines the19th century search for a route to Asia by way of the Northwest Passage through the Arctic Ocean.Author Anthony Brandt describes the many attempts by both land and sea that ended in failure and tragedy,including the1845expedition led by Sir John Franklin.Brandt shows how these brave,yet sometimes foolish,explorers could have avoided starvation,frostbite,and even death if they had copied the survival techniques of the local Inuit people.Some of the more surprising details the book reveals include:IGLOOS The explorers,despite repeatedly watching the Inuit build igloos,insisted on using canvas tents.Tents freeze in sub-zero temperatures and give little protection to anyone inside them.If they had learned to build igloos,the explorers would have been warm even in the worst Arctic weather.SEALSKIN If the explorers had worn sealskin and furs like the Inuit,they wouldn't have suffered from the frostbite that was common among them,but rare among the Inuit.DOG TEAMS Why didn't the British use dog teams to pull their sleds?Pulling sleds themselves was a tradition among many explorers right into the early20th century It cost Scott and his men their lives on their return from the South Pole in1912.The British did get something right,however,when Captain Edward Parry grew salad vegetables in boxes on board his ship.It was known that fresh vegetables and fresh meat prevented scurvy(坏血病),although at that time the reason for this(vitamin C)had not been discovered.Parry's men wouldn't have been as healthy if they hadn't eaten the salads.60.In The Man Who Ate his Boots’the author mainly________.A.introduces some foolish explorersB.focuses on some unsuccessful expeditionsC.analyzes the Inuit people's survival techniquesD.explores the advances in equipment used for expeditions61.According to Anthony Brandt,what should the explorers have done?A.They should have learned more about how seals survived in cold water.B.They should have set up more canvas tents to keep themselves warm.C.They should have helped the Inuit people build igloos.D.They should have used dogs to pull the sleds for them.62.It can be inferred from the passage that________.A.Edward Parry found a way to prevent scurvy by accidentB.Edward Parry's successful voyage was a rare case at that timeC.Edward Parry was the first captain that grew salad vegetables on boardD.Edward Parry's men could have been more healthy if they took vitamin C(C)Everything we know suggests that the universe is unusual.It is flatter,smoother,larger and emptier than a"typical"universe predicted by the known laws of physics if we reached into a hat filled with pieces of paper,each with the specifications of a possible universe written on it,it is unlikely that we would get a universe anything like ours in one pick—or even a billion.The challenge that cosmologists face is to make sense of this specialness.One approach to this question is inflation―the hypothesis(假设)that the early universe went through a stage of fast expansion.At first,inflation seemed to do the trick.A simple version of the idea gave correct predictions for the spectrum of fluctuations in the cosmic microwave background.But a closer look shows that we have just moved the problem further back in time.To make inflation happen at all requires us to fine-tune the initial conditions of the universe.And unless inflation is highly tuned,it leads to a runaway process of universe creation.As a result, some cosmologists(宇宙学家)suggest that there is not one universe,but an infinite number, with a huge variety of properties:the multiverse.There are an infinite number of universes in the collection that are like our universe and an infinite number that are not.But the proportion of infinity to infinity is undefined,and can be made into anything the theorist wants.Thus the multiverse theory has difficulty making any firm predictions and threatens to take us out of the area of science.These other universes are unobservable and because chance dictates the random distribution of properties across universes,suggesting the existence of a multiverse does not let us get to anything about our universe beyond what we already know.As attractive as the idea may seem,it is basically a sleight of hand,which turns an explanatory failure into an apparent explanatory success.The success is empty because anything that might be observed about our universe could be explained as something that must,by chance,happen somewhere in the multiverse.We started out trying to explain why the universe is so special,and we end up being asked to believe that our universe is one of an infinite number of universes with random properties.This makes me suspect that there is a basic but unexamined assumption about the laws of nature that must be overturned.Cosmology has new questions to answer.Not just what are the laws,but why are theselaws the laws?How were they chosen?We can't just hypothesise what the initial conditions were at the big bang,we need to explain those initial conditions.Thus we are in the position of a computer program asked to explain its inputs.It is clear that if we are to get anywhere, we need to invent new methods,and perhaps new kinds of laws,to gain a scientific description of the universe as a whole.63.According to the passage,which of the following statements is true of our universe?A.There are several hypotheses about its early stage.B.There are more than one billion universes similar to ours.C.It is expanding at a greater speed that it did at the stage of the big bang.D.It is different from the predictions made according to the laws of physics.64.What does the writer imply about the hypothesis of inflation?A.It hasn't been challenged.B.It doesn't make much sense.C.It is by far the most reasonable approach.D.It is the simple version of a complicated idea.65.Which word in the passage is similar in meaning to the phrase"sleight of hand"(paragraph4)?A.processB.predictionC.trickD.infinity66.It can be inferred from the passage that the writer___________.A.believes the idea of the multiverse will help us to understand our universe betterB.argues there is a fixed proportion of universes like ours to those unlike oursC.holds computer programs can work better than humans in cosmologyD.thinks some laws of nature that we take for granted may be falseSection CDirections:Complete the following passage by using the sentences given below.Each sentence can be used only once.Note that there are two more sentences than you need.A.Unsurprisingly,when his customers heard about the jokes they didn't see the funny side and the share price of the company crashed.B.All I can say is that it's just as well I'm not famous!C.The same is not true for everyone,particularly if you are famous.D.What makes things worse for the famous is that these mistakes become even more widely publicised because of24-hour news channels and websites.E.This is the kind of thing many people might do privately when they get together with colleagues after work.F.As a result,what was private suddenly became public.Silly Mistakes Hit the HeadlinesWe have probably all had moments when we said the wrong thing.I certainly have. There was the time at university when I met a friend in a coffee bar after class and immediately started complaining about our tutor,who was called Dr Gray.I was going on and on about how miserable she was一strict,boring,unfriendly—and my friend wasn't really saying much.After a minute or so,she interrupted me and said,'Um,I think I should introduce you'.She then turned to this other student who I hadn't really noticed up till then and said,"This is Tracy.Tracy Gray'!Fortunately,the result of putting my foot in it was only an awkward moment and a stony silence.Maybe my friends thought a little less of me,maybe they thought I was an idiot,but no real harm was done.__________67__________Take Gerald Ratner.He was the multimillionaire owner of a chain of shops that sold cheap jewellery.In what was supposed to be a light-hearted speech to some fellow businessmen,he joked about the quality of some of his products.He said some earrings were 'cheaper than a sandwich,but probably wouldn't last as long'.Other products could be sold at such low prices because they were rubbish.__________68__________Ratner had to resign as director and shortly afterwards the company was taken over by a competitor.In some ways,Ratner could be seen as unfortunate in that he was in a semi-private meeting with friends and colleagues he was at ease with,but there happened to be a journalist there.__________69__________And with the rise of social media,there have been plenty of others who have been caught out by the increasingly vague boundaries between our private and public faces.For example,a group of flight attendants made jokes about the engines on their planes failing and complained about their airline and clients(客户).__________70__________Unfortunately,they did it publicly on Facebook and it led tothirteen of them being fired.IV.Summary WritingDirections:Read the following passage.Summarize in no more than60words the main idea and the main point(s)of the e your own words as far as possible.Cities in the SeaThey may be small,but they build big things!Coral polyps(珊瑚虫),which live in the warm,shallow parts of the Earth's oceans,are probably the biggest builders on the planet. Coral polyps turn calcium from seawater into a hard material called limestone.Slowly,they build up a hard skeleton(骨架)around their bodies.When polyps die,their skeletons remain. Young polyps attach themselves to the old skeletons and make new skeletons.Over time, weird and wonderful shapes are slowly built up into amazing coral reefs(珊瑚礁).Scientists sometimes think of coral reefs as underwater cities.A quarter of all known marine species live in reef habitats―there are nearly a thousand coral species.Reefs are also home to millions of sea creatures,like fish,crabs,turtles,and sharks.Humans don't live in coral reef cities,but we benefit from them.Reefs create jobs for people in the fishing industry and other related businesses.Coral reefs are also popular for divers一many countries benefit from the tourists that they stly,chemicals from reef creatures help scientists create new medicines,which help doctors treat different illnesses.Coral reefs are very important,yet we don't take good care of them.Environmental problems have already killed about twenty percent of the world's reefs.About half of the remaining reefs are dying,and experts believe all of Earth's coral reefs will be in danger by 2050.Why are the reefs in such trouble?For one thing,people catch too many reef fish and often damage the reefs—divers sometimes break off pieces of coral.Polluted water also causes problems because reef-destroying algae grows in dirty water.Even air pollution hurts coral reefs.Global warming causes warmer ocean water,which can cause polyps to lose helpful algae.Without that algae,coral turns white.This is called"bleaching”,and if it continues,the coral dies.V.TranslationDirections:Translate the following sentences into English,using the words given in the brackets.72.不努力一把,怎么知道人生会不会有更多的可能?(If)73.过去的三年里,这个曾经无人问津的小村庄吸引了大量游客。
