1. 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.The main point of the first paragraph is that Washington Irving was ().

1. Passage ThirteenTrees are useful to man in three important ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts and floods.Unfortunately， in many parts of the world， man has not realized that the third of these services is the most important.In his eagerness to make money from trees， he has cut them down in large numbers， only to find that without them he has lost the best friends he had.And besides， he is usually too careless to plant and look after new trees.So the forests slowly disappear.This does not only mean that man will have fewer trees.The results are even more serious: for where there are trees， their roots break up soil——allowing the rain to sink in——and also bind the soil， thus preventing it from being washed away easily; but where there are no trees， the rain falls on hard ground and flows away， causing floods and carrying away the rich topsoil.When all the topsoil is gone， nothing remains but worthless desert.Two thousand years ago a rich and powerful country cut down its trees to build warships， with which to gain itself an empire.It set up the empire but， without its trees， its soil became poor and it grew weak.When the empire fell into pieces， there is nothing left except floods and starvation.What is the most important service of trees to man according to the passage?

36. 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.What does the author think of most entrepreneurs?

A. 　They are more willing to risk their own lives.

B. 　They are more ambitious than ordinary people.

C. 　They achieve greater nonconventional success.

D. 　They have more positive qualities than most of us.
