5. Passage SeventeenNo one knows how man learned to make words.Perhaps he began by making sounds like those made by animals.Perhaps he grunted like a pig when he lifted something heavy.Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground.Somehow， he learned to make words.As the centuries went by， he made more and more new words.This is what we mean by language.People living in different countries made different kinds of words.Today there are about fifteen hundred different languages in the world.Each contains many thousands of words.A very large English dictionary， for example， contains four or five hundred thousand words.But we do not need all these.Only a few thousand words are used in everyday life.The words you know are called your vocabulary.You should try to make your vocabulary bigger.You’re supposed to read as many books as you can.There are plenty of books written in easy English for you to read.You will enjoy them.When you meet a new word， you should find it in your dictionary.Your dictionary is your most useful book.You can enlarge your vocabulary by ().

37. 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 imply by saying “this isn’t always the case” (Line 1， Para.3)?

A. 　Ambitious people may not have a greater chance of success.

B. 　Ambitious people may not have more positive qualities.

C. 　Entrepreneurs’ ambition does as much good as harm.

D. 　Entrepreneurs are more naturally driven to success.

5. Passage NineteenA 3-year-old boy who was lost in the woods for two days is now safe at home.But Casey Hathaway told his rescuers that he was not alone in the rainy， freezing cold woods.He said he was with a friend——a bear.The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina.When the other children returned to the house and Casey did not， the family searched the area for almost an hour before calling the police.Police formed a search and rescue team to look for the young boy in the nearby woods.But two days went by and still——no Casey.The woods of North Carolina are home to many black bears， like this one.It seems one of them helped a little boy while he was lost in the woods.Then on January 24， someone called the police saying they heard a child crying in the woods.Police followed up on the information and found Casey at about 9:30 that night.They pulled him out of some briar (荆棘).He was in good health.Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud， rainy weather， but that “he did say he had a friend in the woods that was a bear that was with him.”Hundreds of people helped in the search and rescue efforts， including some 600 volunteers， federal police and members of the military.Hughes told reporters that at no point did he think Casey had been kidnapped (绑架).Doctors at Carolina East Medical Center treated Casey for minor injuries.He was then released to his family on January 25.All the following are mentioned as those helping in the rescue efforts EXCEPT ().
