In a six-week study, experts found people who played online games designed to improve their cognitive(認知的) skills didn't get any smarter.

More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week. They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given a sort of I.Q test before and after the experiment.

Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.

"If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, the study's lead author. "But if you're expecting (these games) to improve your I.Q., our data suggests this isn't the case," he said during a press briefing on Tuesday.

One maker of brain games said the company's games have been proven to boost brain power.

"Their conclusion would be like saying, 'I cannot run a mile in under 4 minutes and therefore it is impossible to do so," Aldrich said in a statement.

"There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, who was not linked to the study and has no ties to any companies that make brain training games.

Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can spark(激發(fā)) new connections between nerves and produce new brain cells. "Fitness changes the building blocks of the brain's structure," he said.

. It can be inferred that the online brain games mentioned in the text are_____________.

A. costly     B. unreliable      C. illegal    D. effective

. Which of the following statements is true about the experiment in the second paragraph?

   A. The experiment lasted for a week.

B. Age didn’t affect the result of the research.

C. Every person played online brain games three times a day.

D. People who didn’t play online brain games did better in I.Q test

. What can we learn from the text?

   A. Playing games which are fun can improve your I.Q.

B. There is a lot of evidence to suggest skills can transfer to the real world.

   C. Do physical activity can boost your brain power.

D. Playing online games can spark new brain cells

The underlined sentence suggests that ___________.

   A. The research was not linked to the study  

B. Those playing the games can score higher in the test

C. playing the games can spark new connections between nerves

D. This isn’t the case that these games can improve your I.Q.

Today, we complete our story about the influential English writer William Shakespeare. He wrote plays and poems during the late fifteenth and early sixteenth centuries, which remain very popular today.

During earlier times, people would probably have learned several ancient Roman and Greek plays. It was not unusual for writers to produce more current versions of these works. For example, in Shakespeare's play "The Comedy of Errors" Shakespeare borrowed certain details from the ancient Roman writer Plautus. For his play "Macbeth", Shakespeare most likely used a work on Scottish history by Raphael Holinshed for information. Shakespeare might have borrowed from other writers, but the intensity（強度）of his imagination and language made the plays his own. While many plays by other writers of his time have been forgotten, Shakespeare and his art live on.

Shakespeare was also influenced by the world around him. He described the sights and sounds of London in his plays. His works include observations about political struggles, the fear of diseases, and the popular language of the city’s tradesmen. Shakespeare's knowledge of the English countryside is also clear. His works include descriptions of deep forests, local flowers, and the ancient popular traditions of rural people.

It would be impossible to list all of the ways in which Shakespeare’s works have influenced the world culture. But the first and greatest example would be his great influence on the English language. During his time, the English language was changing. Many new words from other languages were being added. Shakespeare used his sharp mind and poetic inventiveness to create hundreds of new words and rework old ones. For example, he created the noun forms of "critic", "mountaineer” and "eyeball". Many common expressions in English come from his plays, including "pomp and circumstance（裝腔作勢）"from "Othello", "full circle（繞圈子地）" from "King Lear", etc. The list of cultural creations influenced by Shakespeare is almost endless. From paintings to television to music and dance, Shakespeare was well represented. Shakespeare's plays have been translated into every major language in the world.
