In 1990 Peter Salovey Ph. D and John Mayer Ph. D coined the term Emotional Intelligence. Their research has opened many people’s eyes to the fact that EQ or emotional quotient holds the key to one’s happiness and well being, and helped us to realize that our emotional makeup can be so much more important than our mental, or what we refer to as IQ—intelligent quotient.

IQ is essential for learning and mental development and EQ is much more important for happiness and success. Some time ago a study done in the United States proved that doctors who were impatient and did not exhibit much care towards their patients were more likely to be sued (起诉) for malpractice(渎职), whereas doctors who were caring and attentive to their patients were less likely to be sued even if they made a critical mistake. A woman wrote to newspaper recently telling about her brother. He was apparently a genius but did not get along with people, quit every job he started, and eventually became a taxi driver. These are just a few examples of people with high IQ but low EQ.

We have all known people who did not complete college, but who have become very successful in business. We call them street smart. We also know people who, on the whole, are positive, communicative, pleasant and supportive—these people enjoy a high level of EQ.

Many people wish to improve their EQ for the purpose of becoming happier, more successful, and at the same time more balanced, individuals. The remarkable thing about EQ is that it can always, at any age, be improved, unlike IQ, which remains more or less fixed in adult life.

Now psychologists start workshops focusing on showing people how to increase their EQ. This enables them to accomplish their dreams and desires, rid themselves of negative patterns and shows them that once they master their inner world, their outer world becomes much better.

A. doctors in the United States are often involved in cases

B. working as a taxi driver in the United States requires high EQ

A. They are positive, communicative, pleasant and supportive.

B. They are optimistic and untroubled by difficulties.

C. They are impatient and show little care towards others.

D. They may be very successful in business.

49. It can be inferred that predicting future successes, ______.

A. a person’s brainpower might actually matter less than a person’s character

B. a person’s IQ might be more important than a person’s EQ

C. IQ plays an important role as well as EQ

D. both IQ and EQ are the key points that should be considered

50. Which of following is NOT true according to the passage?

A. People with high IQ are likely to gain knowledge quickly.

B. At work EQ gets you hired easily and IQ gets you promoted.

C. Having a high IQ will help us in some ways but having a high EQ might help us even more.

D. People’s EQ could be raised much more than their IQ.

If the (7) of money by a nation merely raised (8) , argued the quantity theorists, then a "favourable" balance of trade, (9) desired by mercantilists, would increase the supply of money but would not in-crease (10) .

The (14) theory came under attack during the 1930s, (15) monetary expansion seemed ineffective in combating deflation. Economists argued that the levels of investment and government spending were more important than the money supply in determining economic activity.

The tide of opinion (16) again in the 1960s, when experience (17) post-World WarⅡ inflation and new empirical (18) of money and prices— (19) A Monetary History of the United States (1963) by Milton Friedman and Anna Schwartz—restored much of the quantity theory’ s lost prestige. One implication of this theory is that the size of the stock of money must be considered when shaping governmental policies (20) to control prices and maintain full employment.
