Everyone knows that the Frenchmen are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?
At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs (企業(yè)家) in the UK found that 70% felt that their efforts were not appreciated by the British public. Britain is hostile (敵意的) to success, they said. It has a culture of jealousy(嫉妒). 【小題1】  Jealousy is sometimes known as the “green – eyed monster” and the UK is its home.
Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money.  【小題2】  Those given a little were given the chance to destroy the large amount of money given to others – but at the cost of losing their own. Two thirds of the people tested agreed to do this.
【小題3】  . But there is also opposite evidence. The Organization for Economic Cooperation and Development recently reported that the UK is now the world’s fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.
“It is not really success that the British dislike,” says Carey Cooper, a professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems proud or unfair or which separates them from their roots.”
 【小題4】  They set out to do things in their way. They work long hours. By their own efforts they become millionaires.  【小題5】  . It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.

A．This seems to prove that the entrepreneurs were right to complain.
B．The one who owns most money in the end is the winner.
C．As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood.”
D．It is not true that British people are born jealous of others` success.
E. Some were given a little, others a great deal.
F. But instead of being happy they complain that nobody loves them.
G. Perhaps it is the entrepreneurs who are the problem.

Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.  1.  Read on for some techniques worth trying.

1． 2. 

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性癡呆癥), according to a recent study.  3. Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short­term goals appear to do better. In other words, keep your brain looking forward.

2．Go for a walk.

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact，exercise produces chemicals that are good for your brain.  4. 

3．Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.  5. Or go dancing with your friends.

A．Focus on the future.

B．This can be especially harmful to the aged.

C．It should be something like learning gardening.

D．So take a few minutes each day to do some reading.

E．But don't worry if your schedule isn't filled with life­changing events.

F．Luckily, research shows there is a lot you can do to avoid those moments.

G．In other words, when you take care of your body, you take care of your brain.
