A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑)．

    Students are increasingly using laptops for note­taking because of speed and legibility(清晰度)．But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment，students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note­taking skills. Thirty minutes after the talk，they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However，the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said，“While more notes are beneficial，if the notes are taken mindlessly，as is more likely the case on a laptop，the benefit disappears.”

    In another experiment aimed at testing long­term memory，students took notes as before but were tested a week after the lecture. This time，the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding，but that they also lead to superior revision in the future.

    Recently I read the Human Development Report. I couldn't help thinking about another problem which the world is facing--hunger. According to the report, 2,400 people are dying from hunger every day; nearly 13 million in southern Africa will be worried about their food supply because of earthquakes, floods or wars.

    In a word, hunger remains the biggest problem of the world today. It's strange to see that man can travel to the moon, but still doesn't know how to feed himself. You may ask, “Who steals our bread? The first thieves should be population growth, poverty and loss of rich farmland.

    In less developed areas like South Africa, the population grows faster than the crops. It is almost impossible for its government to feed so many people and provide education for them. So it is very important to control the population growth and protect their farmland in countries whose people are suffering from hunger.

    According to the report, the world's food production is enough to feed everyone if it is given away well. But the problem is that the developed countries are eating food that should be given to the poor. Although they are just using their own earning, the fact is that they are coldly watching others starving away.

    Luckily, some developed countries such as Netherlands, Norway and Sweden have done a lot to help those hungry people in African countries. We hope other developed countries will follow them.

    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.

    Filled with much housework, meals and childcare at home, many people feel that being at work sounds more like having a picnic. Even for those who have a happy family life, they feel actually more stressed at home than at work.

    Recently, a study carried out by the researchers at a university in the USA found lower levels of hormone released in response to stress in a majority of subjects when they were at work compared to when they were at home. This was true for both men and women, and parents and people without children.

    Both men and women showed less stress at work. But women are more likely to report feeling happier there. Men were more likely to feel happier at home. Experts say there are other reasons why work is less stressful than home for many. “Paid work is more valued in society,” said Sarah Damaske, the lead researcher on the study, “Household work is boring and not particularly rewarding.”

    We get better at our job with time and the increased competence means less stress and more rewards. Yet none of us, no matter how long we've been doing it, ever truly feels like an expert at parenting or even at marriage.

    The support and friendship of co-workers also offer stress relief. At home, meanwhile, stress spreads and increases quickly. “That's the reason why most housewives wish they were the bread earners,” Dr. Damaske says.

    Much of the advice to families and couples includes the warning to “leave work stress at office” and even to change our mind-set from work to home, for example, a walk around the block. The recent findings, though, suggest our home life, not our attitude, might be due for some change.

Growing up on a tobacco farm, Emma Avery was used to hard times. When she was seven, her family's farmhouse burned to the ground. Her father made a temporary shelter, where eight people had to sleep in two beds. As soon as Emma and her four brothers and two sisters were big enough, they were out in the fields.

Emma would find her comfort in school, even as a C student, thanks to one teacher. When she moved on to middle school, Emma was alarmingly far behind her classmates. She kept her head down, trying not to be noticed, struggling to catch up, and feeling like an outsider.

Then one day, when Emma was 16, a teacher named Mr. Potts changed everything. Looking his students in the eye, Mr. Potts said, "Being a C student does not mean you do not have a valuable contribution to make. Some of you have to work in the fields in the evening and do not have time to study. But if you do your best, you have a gift to give."

The teacher's words made Emma believe she could do well, and she worked harder. In the end she won a scholarship to St. Paul's College, graduated with a degree in elementary education in 1967, and got a job in the public-school system. Then, at George Washington University, she received a master's in education in 1970, and afterwards in the same year she married Ron Smothers.

Over the next six years, Emma taught in public schools in Miami. In 1976, after saving $10,000, she opened her first restaurant in Los Angeles. Eventually Emma stopped teaching, and her business expanded to six restaurants.

In gratitude for what she has been able to achieve, Emma donates a lot. She has no idea how much money she's given away. She says, "Those I want to help are the C students who just need help, direction and confidence."

"Don't get dirty!" was once often shouted by parents angrily watching their children ruin their best clothes. It was unavoidable that children's whites would turn brown before the day was over. 

Today, many parents may secretly wish their children had the chance to pick up a bit of dirt. With the rise of city life, and the attraction of video games and social media, contact with nature is much less than in the past. For many, there is simply no opportunity to get muddy. According to recent research, the dirt outside is teaming with friendly microorganisms (微生物) that can train the immune (免疫的) system and build the body against illnesses, such as anxiety. 

These findings show that outdoor exercise is not only beneficial because of the chance to run around free—but that certain natural materials, such as soil and mud, also have powerful microorganisms which have positive effect on children's health. Outdoor play can also offer valuable learning experiences. For example, the act of rubbing and shaping materials like mud or sand can help children develop their senses and movement. 

Such activities—away from the house or classroom—may also help children to find ways to deal with emotions that may be hard to explore in other environments. So-called "Sandtray Therapy (沙盘疗法)", which includes using sand to express one's thoughts and feelings, is an accepted form of guidance for children who are struggling to speak out their inner emotions. 

Surprisingly, people who spent most of their childhood in the countryside show a better reply to stressful events like public speaking compared with those who grew up in cities. "The people who grew up in cities are kind of ‘walking time bombs' when facing the stress we meet today. However, people who have spent lots of time in nature since childhood are generally stronger in recovery and more positive." says Christopher Lowry, a professor of University of Colorado Boulder.
