(2011·福建四校六地第三次联考)
WHAT can help you make a fortune in the future?Graduating from a top university might not be enough.A new study from the University of Essex in Britain has shown that the more friends you have in school,the more money you’ll earn later.
The idea that popularity could have a serious influence on one’s earning potential shouldn’t come as too much of a surprise.The researchers noted that if you want to get ahead in life,social skills and networking are easily as powerful as talent and hard work.
“If a person has lots of friends,it means that he or she has the ability to get along with others in all kinds of different situations,” said Xu Yanchun,17,from Nantou High School in Shenzhen,who totally agreed with the recent finding.“Also,friends always help each other.They not only create wider social circles for you but lift your mood when you are occasionally in low spirits,” said Xu.She believed that all this helps you “earn a higher salary”.
Maybe that’s why some people think the younger generations
are in the age of Friendaholism (交友狂症)?A woman even complained that the networking website Facebook’s 5,000friend limit was too low for her large reserve of social contacts.
But what does a friend mean?Should friends be regarded as a form of currency?
“Call me uncool,but I think of a friend as an actual person with whom I have an actual history and whom I enjoy actually seeing.It seems,however,that this is no longer the definition of a friend,” said Meghan Daum,who works with the Los Angeles Times in the US.
Daum dislikes the idea that quantity trumps quality in the age of Friendaholism.She thought the idea of friendship,at least among the growing population of Internet social networkers,was to get as many of notreallyfriends as possible.For example,a friend might be someone you might know personally but who could just as easily be the friend of a friend of some
other Facebook friend you don’t actually know.Although she
agreed that social ties grease (润滑) the wheels of life,she also warned,“Too bad one thing money can’t buy is a real friend.”
1.What can friends do in the eyes of Xu Yanchun?
A.They can help you with your schoolwork.
B.They teach you how to make more money.
C.They help you to get rid of sadness and cheer up.
D.They introduce their friends to you.
2.What will be needed if you are to achieve success according to the researchers?
A.Social skills,friends,good mood and fortune.
B.Social skills,networking,talent and hard work.
C.Social skills,networking,potential and fortune.
D.Social skills,talent,hard work and Facebook.
3.We learn that Meghan Daum’s attitude towards friends is somewhat________.
A.uptodate
B.optimistic
C.confused
D.traditional
4.What does the word “trumps” in the last paragraph mean?
A.is better than
B.is equal to
C.is worse than
D.is similar to
(2011·郑州第一次质量检测)
Scientists say they now have proof to support the oldfashioned advice that it’s best to_sleep_on_a_problem.They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day.
The lead researcher Bob Stickgold at Harvard Medical
School said,“Sleep helps us draw rules from our experiences.It’s like knowing the difference between dogs and cats even if it’s hard to explain.”
The US research team studied how well students remembered connections between words and symbols,reports New Scientist.They compared how the students performed if they had had a sleep between seeing the words and having the test,and if they had not slept.They found that people were better able to remember lists of related words after a night’s sleep than after the same time spent awake during the day.They also found it easier to remember themes that the words had in common.But they forgot around one in four more themes if they had been awake.
Prof.John Groeger,University of Surrey’s Sleep Research Centre,said,“People have been trying for years to find out what the purpose of sleep is,as we know that only certain parts of it have a restorative (促使康复的) value.”
“We form and store huge numbers of experiences in the head every day,and sleep seems to be the way the brain deals with them all.”
5.The phrase “to sleep on a problem” in Paragraph 1 most likely means “________”.
A.to pay full attention to a problem
B.to wait until the next day for a decision
C.to sleep to forget a problem
D.to have difficulty in sleeping
6.In the study by the US research team,students were asked to________.
A.put together words of similar meanings
B.remember words and their meanings
C.show their knowledge of words
D.make up lists of related words
7.Which of the following may be easier to remember?
A.Themes learned right before the test.
B.Rules from personal experiences.
C.Words learned before a good sleep.
D.Ideas stored together in the brain.
8.What may be the importance of the research?
A.It shows that sleep may help us manage information.
B.It helps find out the common themes of words.
C.It tells us that more sleep can improve health.
D.It proves the value of oldfashioned advice.
