A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth.

Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught(though people can raise their grades on tests of it by practicing).

But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works.

The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it.This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence.

First they measured fluid intelligence of volunteers using standard tests.Then they trained each in a complicated memory task—the child’s card game,in which they had to recall a card they saw and heard.During the course, they needed to ignore irrelevant items, monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time.

The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively.To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training.

The results, published Monday in The Proceedings of the National Academy of Sciences,were striking.Improvement in the trained groups was a lot greater.Moreover,the longer they trained, the higher their scores were.All performers,from the weakest to the strongest,showed significant improvement.

“Our results show you can increase your intelligence with proper training.” said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”

The researchers thought the key to improving the intelligence was ______________.

       A.memorizing telephone numbers         B.improving working memory

       C.training in concentration              D.recalling a card

The following aspects of the training help increase intelligence EXCEPT___________.

       A.ignoring irrelevant items                  

       B.monitoring ongoing performance

       C.managing two tasks at the same time         

       D.using previous experience

When the experiment was conducted, the researchers______________.

       A.trained the four groups for the same period of time

       B.only made comparisons between the four groups

       C.compared the four groups with control groups

       D.trained the four groups together

By writing the article,the writer intends to ______________.

       A.inform the readers of a new study

       B.call on people to be trained to increase intelligence

       C.prove one’s born brainpower can be improved

       D.tell people the improved intelligence will last forever

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that

is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not.

Greenhorn now refers to ____.

A. a person who is new in a job                  B. a new solider

C. a young horse                                      D. None of above

A person who has a green thumb is a person ____.

A. who is good at growing plants B. whose thumbs are in green color

C. whose garden is greener than others’

D. who is younger than his neighbors

The author is actually talking about ____.

A. colors               B. language        C. politics                     D. agriculture 

Which of the following statements is NOT true according to the passage?

A. In about the 16th century, a greenhorn meant an experienced soldier.

B. The Green Revolution may have some connection with green thumbs.

C. The green-eyed monster was probably created by William Shakespeare.

D. The green-eyed monster can be used to describe a person who is jealous.
