39. Questions 36 to 40 are based on the following passage.Most of us in the entrepreneurial community are blessed — or cursed — with higher-than-average ambition.Ambitious people strongly desire accomplishments and are willing to take more risks and spend more effort to get them.Overall， this is a positive quality， especially for people trying to build their own businesses.Apparently， if you’re more naturally driven to set goals， you are more likely to succeed.Actually， this isn’t always the case.In fact， in some cases， extreme ambition may end up doing more harm than good.One major side effect of excessive ambition is the tendency to focus too determinedly on one particular vision or end goal.This is problematic because it hinders your ability to adapt to new circumstances， which is vital if you want to be a successful entrepreneur.If a new competitor emerges to threaten your business， you may need to change direction， even if that means straying from your original vision.If you have too much ambition， you’ll find this hard， if not impossible.Few people are successful when they try to build their first brand.Unfortunately， for the most ambitious entrepreneurs， a failure is seen as disastrous， and impossible to recover from.It’s a clear departure from the intended plan toward the intended goal.For people with limited ambition， however， failure is viewed as something closer to reality.Remember， failure is inevitable， and every failure you survive is a learning experience.Ambitious people tend to be more materialistically successful than their non-ambitious counterparts.However， they’re only slightly happier than their less-ambitious counterparts， and tend to live significantly shorter lives.This implies that even though ambitious people are more likely to achieve conventional “success，” such success means nothing for their health and happiness—and if you don’t have health and happiness， what else could possibly matter?Clearly， some amount of ambition is good for your motivation.Without any ambition， you wouldn＇t start your own business， set or achieve goals and get far in life.But an excess of ambition can also be dangerous， putting you at risk of burnout， stubbornness and even a shorter life.How do the most ambitious entrepreneurs regard failure in their endeavor?

A. 　It will awaken them to reality.

B. 　It is a lesson they have to learn.

C. 　It means the end of their career.

D. 　It will result in a slow recovery.

3. 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.Man’s forehead will grow larger because ().

2. 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.What is implied by the mention of Scott， Poe and Hawthorne?

43.The government should come up with a better solution to the problems caused by the high price of petrol.

5. Passage Twenty-NineHow can we get rid of garbage (垃圾)? Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today.Some people think that man might be able to solve both problems at the same time.They suggest using garbage as an energy source， and at the same time it can save the land to hold garbage.For a long time， people buried garbage or dumped (倾倒)it on empty land.Now， empty land is scarce.But more and more garbage is produced each year.However， garbage can be a good fuel to use.The things in garbage do not look like coal， petroleum， or natural gas; but they are chemically similar to these fossil fuels.As we use up our fossil-fuel supplies， we might be able to use garbage as an energy source.Burning garbage is not a new idea.Some cities in Europe and the United States have been burning garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby buildings.In Paris， France， some power plants burn almost 2 million metric tons of the city’s garbage each year.The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited.Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount of garbage piling up on the earth.The best title for the passage may be ().
