Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory.

According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in.

" We've always known that caffeine has cognitive-enhancing effects (促智效果) , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo(无效对照剂) or a 200-milligram caffeine tablet.

To check the caffeine levels of their test subjects, the research team took saliva samples (唾液样品) from them before they took their tablets and again one, three and 24 hours after- wards.

Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day.

The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier.

The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same.

"We also know that caffeine is associated with health and longevity(长寿) and may havesome protective effects from cognitive decline like Alzheimer' s disease (阿尔茨海默症). " said Yassa.

Shirley Temple, who died on February 10, 2014, was that rare example of a Hollywood child star who, when the cameras stopped rolling, carved out a new career.

For four years, she was Hollywood’s biggest box-office star representing the kind of sweet, innocent girl that everyone wanted as their daughter. However, years later, she reappeared as a successful politician.

Shirley Temple was born in Santa Monica, California on 23 April 1928. Encouraged by her mother, she learned to dance while she was just three.

In 1934, Stand Up and Cheer became her first film and the film was a great success. At the age of six she was earning $1,250 a week — more than $21,000 at today’s values.

Across the world, audiences flocked to see her in films such as Little Miss Marker, The Little Colonel and The Littlest Rebel.

In 1935 she was awarded a special Oscar (Academy Award) and her foot and hand prints were added to those of stars such as Jean Harlow and Mary Pickford outside Grauman’s Chinese theatre in Hollywood. The peak of her film career came in 1939 when The Little Princess became a box-office success.

Temple starred in a total of 43 feature films. But she found it difficult to maintain her film career in adulthood and retired from Hollywood in 1950.

She disappeared from the spotlight for nearly 20 years. She returned to the public eye in 1967, as a Republican candidate for Congress. When Nixon became president, he rewarded her with an appointment to the American delegation to the United Nations. Then, in 1974, President Ford appointed her the United States Ambassador(大使) to Ghana. George Bush Snr, appointed her Ambassador to Czechoslovakia.

Shirley Temple drew a line between her childhood stardom and her later political career. “Some people are stuck on this image of the little girl,” she once said. “She is not me. We shouldn’t live in the past; my life is now.” Nevertheless, for many across the world, the name Shirley Temple always called to mind a superstar child.

Children and teenagers who spend lots of time in front of screens---especially TVs---are easier to get more weight as they grow, according to a new study.

The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits.

Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese(肥胖的). Twenty-four percent of the 3,500 boys were also above a healthy weight.

The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games.

From one survey to the next, each one-hour increase in children’s daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI)(体质指数), which measures weight in connection with height. There’s an increase of about half a pound in weight per extra hour of TV.

“The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,” says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston.

“It's important for parents to know that all the obesity-causing(引起肥胖的)screens really should be limited in their children's lives.” Falbe says. “When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink.” What's more, she says, “they can get into a hibernating(冬眠) state on the sofa, even if children are sitting down while playing a computer game.”

fatter.

A. 0.1 B. 0.5

C. 0.3 D. 0.7

4.According to Falbe , what should parents do to stop children getting fat?

A. Limiting the time of children watching TV.

B. Buying children food advertised on TV.

C. Not allowing children to watch TV.

D. Encouraging children to play computer games.

 

There was a time when the owners of shops and businesses in Chicago had to pay large sums of money to gangsters(匪徒)in return for “protection”. If the money was not paid immediately, the gangsters would quickly put a man out of business by destroying his shop. Getting “protection money” is not a modern means. As long ago as the fourteenth century, an Englishman, Sir John Hawkwood, made the remarkable discovery that people would rather pay large sums of money than have their life work destroyed by gangsters.

Then Sir John Hawkwood arrived in Italy with a group of soldiers and settled near Florence. He soon made a name for himself and came to be known to the Italians as Giovanni Acuto. Whenever the Italian city-states were at war with each other, Hawkwood used to hire his soldiers to those who were willing to pay the high price he demanded. In times of peace, when business was bad, Hawkwood and his men would march into a city-state and, after burning down a few farms, would offer to go away if protection money was paid to them. Hawkwood made large sums of money with this method. In spite of this, the Italians regarded him as a sort of hero .When he died at eighty, the Florentines gave him a state funeral and had his picture painted, which was in memory of “this bravest man”.
