问答题Practice 4 The furthest we have been is the Moon. If we want to travel into deep space, beyond our own backyard, the Solar System, we’ll need a new breed of spacecraft. It may be the oldest clich6 in town, but in the not too distant future science fiction will turn into science fact. The fantastic spaceships of sci-fi comic books and novels will no longer be a figment of our creative imagination; they may be the real vision of our future. Engineers and designers are already designing craft capable of propelling us beyond Earth’s orbit, the Moon and the planets. They’re designing interstellar spaceships capable of travel across the vast emptiness of deep space to distant stars and new planets in our unending quest to conquer and discover. Our Universe contains over a billion galaxies; star cities each with a hundred billion inhabitants. Around these stars must exist planets and perhaps life. The temptation to explore these new realms is too great. First things first-we’ll have to build either a giant orbiting launch platform, far bigger than the International Space Station (ISS), or a permanently manned lunar base to provide a springboard for the stars. Some planners feel we should limit ourselves to robotic probes, but others are firmly committed to sending humans. “There’s a debate right now about how to explore space,” says astronaut Bill Shepherd, destined to be the first five-aboard Commander of the ISS. “Humans or machines-I think they’re complementary.” The Human Problem Space is the most hostile environment we will ever explore. Even a single five-hour spacewalk requires months of training, and a vast technical backup to keep it safe. The astronauts and cosmonauts who live aboard the ISS will be there for only a few weeks or months; if we want to travel into deep space it could take years. First we’ll have to find out just how long the human body can survive in a weightless environment. In zero gravity, four pints of body fluid rush from the legs to the head where it stays for the duration of the mission. Astronauts often feel as if they have a permanent cold, and disorientation can become a major problem. In space there’s no physical sensation to let you know when you’re upside down and astronauts have to rely on visual clues from their surroundings. A few hours after reaching orbit, one in three of all astronauts will experience space sickness-a feeling rather like carsickness. And weightless conditions lead to calcium being leached from the bones, and problems with the astronauts’ immune systems. Trillions of rocky fragments-meteoroids-roam our Solar System at speeds of up to150, 000 miles an hour. A meteoroid no bigger than a grain of salt could pierce a spaceship window. Protection from the extreme hazards of space is going to need some clever technology. Space is also full of lethal radiation-X-rays, gamma rays and the high-speed particles called cosmic rays.

Text 3 Up until a few decades ago,our visions of the future were largely-though by no means uniformly-glowingly positive.Science and technology would cure all the ills of humanity,leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable,as we have gained a deeper appreciation of the range of threats facing us,from asteroid strike to epidemic flu and to climate change.You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years-so why shouldn't we?Take a broader look at our species'place in the universe,and it becomes clear that we have an excellent chance of surviving for tens,if not hundreds,of thousands of years.Look up Homo sapiens in the"Red List"of threatened species of the International Union for the Conversation of Nature（IUCN）,and you will read:"Listed as Least Concern as the species is very widely distributed,adaptable,currently increasing,and there are no major threats resulting in an overall population decline."So what does our deep future hold?A growing number of researchers and organisations are now thinking seriously about that question.For example,the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully,it may be easier to think about such lengthy timescales than about the more immediate future.The potential evolution of today's technology,and its social consequences,is dazzlingly complicated,and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.That's one reason why we have launched Arc,a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance.As so often,the past holds the key to the future:we have now identified enough of the long-term patterns shaping the history of the planet,and our species,to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad.To be sure,the future is not all rosy.But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans,and to improve the lot of those to come.33.Which of the following is true according to Paragraph 5?A.Arc helps limit the scope of futurological studies.B.Technology offers solutions to social problem.C.The interest in science fiction is on the rise.D.Our Immediate future is hard to conceive.

We need to follow the lead of Britain's families and put in the hard work to renew the contract between the generations.You don't get a better Britain by chance-you have to build it.Nor are we likely to overcome the divides facing our country by accident-we have to unify it.But when it comes to ensuring that Britain works for all generations,young and old,as a society we too often leave il to chance,something families would never do.The giving and taking of the generational contract,in which we support young and old,feels like the natural order of things.Cont.ributing when we can and being looked after when in need is what we do every day as 14 million parents bring up their children.And just as that contract underpins our families,it has long underpinned our socieLy and welfare state.But this intergeneraLional conLiact is under pressure.We are already failing to provide the social care our older generations deserve,need and expect.And this is before the real pressures,and a~24bn bill,from delivering on our health and care obligations in an ageing society arrive in the next decade.Solution after solution has been panned,binned or pushed into the long grass by government after government.The need co renew our intergenerational conLract is clear and urgenl,bul doing so is far from easy.It requires new thinking and tough trade-offsPfrom how we deal wich the fiscal pressures of an ageing society in a way that is generationally fair,to how we deliver the housing young people need while respecting the communities everyone values.And the polit,ics are far from straightforward.Renewal should involve an agenda appealing to all generations,but voters'party preferences have never been so starkly divided by age.This state of affairs-with the Conservatives reliant on older people who are most likely to vote,and Labour sitting on a lead amongst younger generations who represent the fucure of British elections-is not desirable for the parties themselves or our counlry as a whole.We need our political leaders co rise to this challenge with an appeal to all generations.It can be done,as the forthcoming final report of the Incergenerational Comm]ssion will lay out.We can deliver the health and care older generations deserve,withoul simply asking younger workers to bear all the costs.We can do more to promote educacion and skills,especially for those who have not chosen on the university route.We can provide more security for yoimg people,from the jobs they do to the homes they renL.And we can show younger generations thal owning a home is a realit,y not a dislanl prospect in 21st-century Britain.Such an appeal across generations is che route to building a better Bricain-and a more united one,too.Which of the following is TRUE about renewing the contract?A.The new contract will be tailored to meet young people's needs.B.The housing issue may be one of top priorities of the new contract.C.The two parties may have different plans for the new contract.D.The needs of all generations have been considerect in che new contract.
We experience a burst of pleasure when we share our thoughts,and this drives us to communlcate.It is a useful feature of our brain,because it ensures that knowledge,experience and ideas do not get buried with the person who first had them,and that as a society we benefit from the products of many minds.Of course,in order for that to happen,merely sharing is not enough.We need to cause a reaction.Each time we share our opinions and knowledge,it is with the intention of having an impact on others.Here's the problem,though:we approach this task from inside our own heads.When attempting to create impact,we reflect on what is persuasive to us,our state of mind.our desires and our goals.But if we want to affect the behaviours and beliefs of the person in front of us,we need to understand what goes on inside their head.
共用题干The Need to RememberSome people say they have no memory at all:"I just can't remember a thing!"But of course we all have a memory.Our memory tells us who we are.Our memory helps us to make use in the present of what we have learnt in the past.In fact we have different types of memory.For example,our visual memory helps us recall facts and places.Some people have such a strong visual memory that they can remember exactly what they have seen,for example,pages of a book,as a complete picture.Our verbal（言语的）memory helps us remember words and figures we may have heard but not seen or written:Items of a shopping list,a chemical formula,dates,or a recipe.With our emotional（情感的）memory, we recall situations or places where we had; strong feelings,perhaps of happiness or unhappiness. We also have special memories for smell,taste, touch and sound,and for performing physical movements.We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds-enough to remember a telephone number while we dial.Our long-term mem-ory,on the other hand,may store items for a lifetime. Older people in fact have a much biter long-term memory than short-term .They may forget what they have done only a few hours ago,but have the clearest remembrance（记忆）of when they were very young.Psychologists tell us that we only remember a few facts about our past,and that we invent the rest. It is as though we remember only the outline of a story.We then make up the details. We of-ten do this in the way we want to remember them,usually so that we appear as the heroes of our own past , or maybe victims needing sympathy（同情）.

问答题Practice 1 We have learned from our Embassy that you are interested in importing Chinese silk products. We are a long-established exporter of silk products in China and we have a very good reputation both at home and abroad. Our products sell well all over the world and highly valued by our customers for their excellent quality and fine workmanship(工艺). Enclosed are our catalogue and price list covering all the products. We are looking forward to your early reply.
问答题Practice 7 That we are in the midst of crisis is now well understood. Our nation is at war, against a far- reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our healthcare is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet. On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord. On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics. This is the journey we continue today. We remain the most prosperous, powerful nation on Earth. Our workers are no less productive than when this crisis began. Our minds are no less inventive, our goods and services no less needed than they were last week or last month or last year. Our capacity remains undiminished. But our time of standing pat, of protecting narrow interests and putting off unpleasant decisions - that time has surely passed. Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America. (Barack Obama: Inaugural Address)

问答题Practice 6 None of us can afford to be complacent about our command of English. For most of the time, of course, there is no problem: we are dealing with family and friends on everyday affairs; and what is more, we are usually talking to them, not writing. It is in ordinary talk to ordinary people on ordinary matters that we are most at home, linguistically and otherwise. And fortunately, this is the situation that accounts for the overwhelming majority of our needs in the use of English. Problems arise as soon as the context is somewhat out of the ordinary. We suddenly need to address a cousin about the death of her husband; or we are writing to our employer to explain temporary absence; composing the minutes of a particularly delicate committee meeting; even just drafting an announcement to pin on the club notice board. This is when we may—or should—pause and wonder about idiom, good usage, the most appropriate way of putting things. There is the risk of sounding too casual, too colloquial, too flippant.
