    Jessica Tandy probably is best known for winning an Academy Award in 1989 for the movie Driving Miss Daisy. She was the oldest person to have won the award. But for many years, she had received praise for her great performances.

    Jessica Tandy was born in London in 1909. After her father died, her mother taught and took other jobs at night to make extra money to raise her, three children. Jessica's older brothers showed an interest in the theater and often put on shows at home. Jessica said later that she was terrible in all of them. But she said taking part in those plays as a child created a desire in her to be someone else.

    Jessica loved going to the theater. This love led her to attend an acting school in 1924. She performed in her first play called The Manderson Girls at 18. But few people watched this play. In 1932, she married the famous actor Jack Hawkins. Their wedding pictures were on the front page of many British newspapers. In the same year, critics in London recognized her great acting skill in her performance in the play Children in Uniform.

    In 1940, Jessica ended her first marriage and moved to the USA. In New York, she met actor Hume Cronyn. Two years later, they married and moved to Hollywood.

    Her turning point came in 1947 when she played the lead part in Tennessee Williams' play A Streetcar Named Desire. Tandy won the first of her four Tony awards for best actress in it. After that Hollywood producers began to choose her to be in the movie.

    Jessica Tandy said she hated seeing herself in the movies. She was surprised when she won the Academy Award for Driving Miss Daisy. She said that the wonderful part she had made up for her lack of experience in movies.

    Teenagers around the world can be happy with the news that the brain will ignore parents' order when they use their smart phones. A new scientific study from the University College London has shown that humans may temporarily go deaf when they're focusing on something visual (视觉的) at the same time.

    The researchers played the normal-volume sounds in the background. And 13 volunteers experienced inattentional deafness as their visual tasks became increasingly difficult. "We found that when volunteers were performing the difficult visual task, they were unable to hear sounds that they would normally hear," Maria Chait said in a statement. "The brain scans showed that people didn't filter out the sounds on purpose. They were not actually hearing them in the first place."

    The findings, published in the Journal of Neuroscience, suggest that the centre of sights and the center of sounds share limited resources. Inattentional deafness is a common everyday experience and the study explains why, according to UCL Institute of Cognitive Neuroscience Professor Nili Lavie.

    If you try to talk to someone focusing on a book, game, or television program and don't receive a response, they aren't necessarily ignoring you. They simply might not hear you at all. This could also explain why you might not hear your bus or train stop being announced if you're lost in your phone, book or newspaper. However, some loud sounds will still be able to break through.

    Some situations could become possibly dangerous when the quieter ones go unheard. As you can imagine, in the operating room, when a doctor concentrates on his work, he might not hear the equipment beeping. It also applies to drivers who center on complex directions. Fortunately, experts have given us some useful tips on preventing such situations.

    It's nothing unusual for people to multitask nowadays. But the ability to do a number of things at the same time could be different between the two sexes.

    A team of UK researchers recently compared the performances of 120 women and 120 men in a computer test about switching(转换) between tasks of counting and shape recognition.

    Men equalled women when tasks were done one at a time. But when the tasks were mixed up, there was a clear difference. According to the paper published in the journal BMC Psychology, both women and men slowed down and made more mistakes as the switching became more rapid. But men were slower, taking 77 percent longer to answer, while women took 69 percent longer.

    To make the experiment more connected to day-to-day life, researchers tried a second test. A group of women and men were given eight minutes to complete a series of everyday tasks, such as finding restaurants on a map, doing simple math problems, answering a phone call, or deciding how they would search for a lost key in a field.

    Once again, women performed better than men in the test, especially in the key-searching task.

    Where do women get the ability to keep organized under pressure better than men? Researchers believe that it has its origins in evolution(进化). In ancient times, women had to keep an eye on children while cooking meals. Meanwhile, men only needed to focus on hunting.

    However, as with all studies, the results don't necessarily apply to every single person in the world. "We don't mean that men can't multitask, or that only women can," researcher Keith Laws of the University of Hertfordshire, UK, told BBC News. "We are saying that the average woman is better able to organize her time and switch between tasks than the average man."

    Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

    The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who have suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

    Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients(接受者).

    On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

    Although toys packaging says it's educational, it doesn't make it so. That's the finding from a new study in JAMA Pediatrics that found some toys being marketed as language promoters got in the way of learning.

    Research shows that for kids to understand, speak and eventually read or write a language, they need to hear it - lots of it. And it's never too early for parents and to caregivers to get talking. That explains the booming industry in talking electronic toys that claim to help kids learn language.

    Professor Anna Sosa, of Northern Arizona University, led the study and says she gave families three different kinds of toys to play with: books, traditional toys like humble blocks and a shape sorter, and electronic toys. Sosa says she picked those toys because they are advertised in their packaging as language-promoters for babies between the ages of 10 and 16 months.

    "We had a talking on farm-animal names and things," Sosa says of the electronic toys. "We had a baby cell phone. And we had a baby laptop. So you open the cover and start pushing buttons, and it tells you things. The parent-child couples were asked to play separately with each type of toy over the course of three days."

    "When there's something else that's doing some talking, the parents seem to be sitting on the sidelines and letting the toy talk for them and respond for them," Sosa says. "That's bad because the best way a toy can promote language in infants and toddlers is by stimulating interaction between parent and child. There's simply no evidence that a young child can learn language directly from a toy. It isn't responsive enough. It isn't social."

    As for the other toys, traditional blocks and puzzles stimulated more conversation than the electronic toys, and books outscored them all. But don't underestimate the humble block. While traditional toys fell short of books in interaction quantity, Sosa notes, they kept pace in terms of quality.
