Are you interested in students in other countries: Do they also have so much homework like you? What do they do in their spare time?

    On April 8,a report came out on the lives of high school students in China,Japan,South Korea and the US.It surveyed（调查）around 6,200 students from the four countries last year.You will find the answers to many of your questions in this report.

    Who study hardest?

    Chinese students spend the most time studying.Nearly half of Chinese students(48.6%) spend more than two hours on their homework every day.That's much more than students of the US(26.4%),Japan(8.2%) and South Korea (5.2%).

    Who sleep most often in class?

    Japanese students fall asleep in class most often.About 45% of them said they sometimes sleep in class.In South Korea, it's 32%;in the US,21%;and 5% in China.

    Who are the most distracted（分心的）?

American students are the most active in class,but also the most distracted.64.2% said they chat with friends in class;46.9% said they eat snacks in class;and 38.9% said they send emails or read storybooks in class.

    What do they do after school?

    In their spare time, most Chinese students study or surf the Internet.Most American students go out to play with their friends.Most Japanese students do physical exercises.Most Korean students watch TV.

    Children often suffer pain and insecurity when their parents separate.When my ex-husband and I split up after 10 years of marriage,our daughter was 5 years old and my son only 3.We decided to consult a psychologist about the best way to explain this new situation to the children.

    She shared with us this special story about a land turtle and a sea turtle,which we then used to help them better comprehend. Once upon a time,a land turtle (Mommy) met a sea turtle (Daddy) close to a beautiful shore.Soon they fell deeply in love and decided to get married.For a time,they continued to live at the water's edge so that Mommy could sit on the sand and keep dry and warm,while Daddy sat in the shallow water to keep cool.A few years later two baby turtles arrived (you both!).They were very special indeed and looked a little like each of their parents.

    But as the years went by,Daddy sea turtle started spending more and more time in the ocean as he traveled deeper and deeper to look for pearls.Mommy land turtle also started wandering up into the sands to hunt for food in the woods.Little by little,Daddy and Mommy turtle started to drift further and further apart.Finally one day,Mommy and Daddy turtle decided they didn't want to live together anymore.The little turtles continued to spend time with each of their parents.They made lots of friends with all the fish,dolphins and whales in the ocean and also many friends with the rabbits,deer,and foxes in the woods.In fact they grew up to be a new kind of turtle that could live both in the ocean and on the land.

    Over the years,this tale of the land and sea turtle has helped my children cope with and accept the fact that my marriage to their father was over.They know that we once loved each other very much and they were born out of true love.

    Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

    I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.

    The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren't jealous of him.

    In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person's emotions, he will certainly like it a lot.

    Native to America, the cane toad (癞蛤蟆) was introduced to Northern Queensland 70 years ago to control sugarcane beetles (甘蔗害虫). The toads failed in that duty but spread across Queensland and into neighboring northern areas.

    Now it calmly invades(侵略) the stats of Western Australia and New South Wales ( NSW). NSW wildlife experts fear the amphibians － which have poisonous backs that kill hungry predators (食肉动物) 一will have a terrible effect on native animals.

    Those fears may be about to be realized. Australia's leading government research body, the Commonwealth Science and Industry Research Organization (CSIRO), forecasts that a rise in average temperatures will make NSW an ideal living place for the cane toads.

    Tony Robinson, head of CSIRO's Wildlife, Pests, and Diseases Program, said climate change is increasing the amount of suitable living place for the cane toads.

    “With climate change, the cane toads might go down as far as Sydney and some areas of Western Australia,” Robinson said.

Recent estimates put the pace of the toads' westward march at nearly 17 miles (27 kilometers) a year and slightly slower from north to south.

    “More southerly (南部的) cities, such as Melbourne and Adelaide, would likely remain too cold and dry to ever suit the toads,” Robinson noted, “but Perth could expect cane toads in five years' time.”

    Sydney could see their arrival in the next 20 years.

    Robinson said there is no method that will keep the toads under control.

    The cane toads already cover at least half of Queensland and most of the northern country. The toads are believed to number in the billions.

    A Venezuelan virus was tried in the 1990s but had to be given up after it was found to also kill native frog species. Scientists and governmental bodies believe a national approach is needed.

    The main threat the toads cause to species such as dingoes, and crocodiles is the poison contained in glands (腺) on each of their shoulders. The poison sprays out when the toads are threatened or handled roughly. The poison is made up of 14 different chemicals.

    Cane toads also compete, and usually win, the hunt for food and living space.

    "”If the government and other states combine resources, I believe we can achieve a very practical biological-control research program,” Bums said.

    What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can, in fact, we are swimming in it -literally.

    Hydrogen is one of the building blocks of the universe. Our own sun is basically, a big，dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.

    The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.

    Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030. It makes sense to produce as much hydrogen as possi­ble as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.

    Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen "fuel cells" for computers and mobile phones have already come on to the market Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.

    The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution, the only by-product of creating hydrogen is pure drinking water something that is very scarce in many parts of the world. But that is not where the good news ends, once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth's popula­tion that has no electricity.

    And electricity creates wealth. In South Africa over the last decade there has been a large programmer of electrification. Thanks to the programmer, people do not have to spend their days looking firewood to burn for heat and with electric light, they can work long into the night

Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the "worldwide hydrogen web", which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.

    Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hy­drogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
