1. Passage Twenty-OneWhat will man be like in the future—in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today.For man is slowly changing all the time.Let us take an obvious example.Man, even five hundred years ago, was shorter than he is today.Now, on average, men are about three inches taller.Five hundred years is relatively short period of time, so we may assume that man will continue to grow taller.Again, in the modern world we use our brains a great deal.Even so, we still make use of only about 20% of the brain’s capacity.As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones.This is likely to bring about a physical change to the head, in particular the forehead will grow larger.Nowadays our eyes are in constant use.In fact, we use them so much that very often they become weaker and we have to wear glasses.But over very long period of time it is likely that man’s eyes will grow stronger.On the other hand, we tend to make less use of our arms and legs.These, as a result, are likely to grow weaker.At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.In the future, then, both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at.This may well be true.All the same, in spite of all these changes, future man will still have a lot in common with us.He will still be a human being, with thoughts and emotions similar to our own.The passage tells us about ().

37. Questions 36 to 40 are based on the following passage.Some people have said aging is more a slide into forgetfulness than a journey towards wisdom.However, a growing body of research suggests that late-in-life learning is possible.In reality, education does an aging brain good.Throughout life, people’s brains constantly renovate themselves.In the late 1960s, British brain scientist Geoffrey Raisman spied growth in damaged brain regions of rats through an electron microscope; their brains were forging new connections.This meant brains may change every time a person learns something new.Of course, that doesn’t mean the brain isn’t affected by the effects of time.Just as height usually declines over the years, so does brain volume: Humans lose about 4 percent every decade starting in their 40s.But that reduction doesn’t necessarily make people think slower; as long as we are alive and functioning, we can alter our brains with new information and experiences.In fact, scientists now suspect accumulating novel experiences, facts, and skills can keep people’s minds more flexible.New pathways can strengthen our ever-changing mental structure, even as the brain shrinks.Conventional fixes like word puzzles and brain-training apps can contribute to mental durability.Even something as simple as taking a different route to the grocery store or going somewhere new on vacation can keep the brain healthy.A desire for new life challenges can further boost brainpower.Research about aging adults who take on new enterprises shows improved function and memory as well as a reduced risk of mental disease.Openness—a characteristic defined by curiosity and a desire for knowledge—may also help folks pass brain tests.Some folks are born with this take-in-the world attitude, but those who aren’t as genetically gifted aren’t necessarily out of luck.While genes can encourage an interest in doing new things, a 2012 study in the journal Psychology and Aging found completing reasoning tasks like puzzles and number games can enhance that desire for novel experiences, which can, in turn, refresh the brain.That’s why brain scientist Richard Kennedy says “It’s not that old dogs can’t learn new tricks.It’s that maybe old dogs don’t realize why they should.”What can we conclude from Geoffrey Raisman’s finding?
A. Brain damage seriously hinders one’s learning.
B. Brain power weakens slower than we imagine.
C. Brains can refresh and improve with learning.
D. Brains forge connections under new conditions.

5. Passage EighteenAn idea that started in Seattle’s public library has spread throughout America and beyond.The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.In addition to encouraging reading as a pursuit (追求)to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools.The idea came from Seattle librarian Nancy Pearl who launched the “If All of Seattle Read the Same Book” project in 1998.Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has expanded to many other American cities, and even to Hong Kong.In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the “One Book, One Chicago” program.As a result, reading clubs and neighborhood groups sprang up around the city.Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about the plot and character.The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population.This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity can be achieved.Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than into discussion about a book itself.Ultimately, as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process, or have enjoyed speaking to someone with whom they would not otherwise have (shared a word).According to Nancy, the degree of success of the project is judged by ().

3. Passage Twenty-ThreeWashington Irving was America’s first man of letters to be known internationally.His works were received enthusiastically both in England and in the United States.He was, in fact, one of the most successful writers of his time in the country, and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States.The respect in which he was held was partly owing to the man himself, with his warm friendliness, his good sense, his urbanity, his gay spirits, his artistic integrity, his love of both the Old World and the New.Thackery described Irving as “a gentleman, who, though himself born in no very high sphere, was most finished, polished, witty; socially the equal of the most refined Europeans.” In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young, uncultured nation—and he received the medal of the Royal Society of Literature.America made him ambassador to Spain.Irving’s background provides little to explain his literary achievements.A gifted but delicate child, he had little schooling.He studied law, but without zeal, and never did practice seriously.He was immune to his strict Presbyterian home environment, frequenting both social gatherings and the theatre.Which of the following best describes the effect of Irving’s Presbyterian background on his life?
