　　Nuclear energy has always been controversial．But since the tsunami and nuclear disaster in Fukushima(Japan)last year the issue is back in the headlines．And the world is divided-some countries are planning more nuclear plants, while others have promised to shut theirs down．

　　After Fukushima, Germany decided to switch off all its nuclear plants by 2022．Switzerland and Italy are also phasing out nuclear power．But France and the United States remain staunch supporters of atomic energy．In fact, almost 80％ of France's electricity comes from nuclear power, the highest percentage in the world．And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan．”

　　Nuclear supporters claim nuclear power can help the environment．Unlike fossil fuels, nuclear power doesn't create greenhouse gases．So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change．Britain's chief scientific adviser(John Beddington)supports this view．He recently said that the world doesn't have the luxury of ignoring nuclear energy．

　　Nuclear power is also relatively cheap．Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment．This higher cost of using “green energy” is usually passed onto the consumer．So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills．This is of particular concern while the world economy is in such bad shape．

　　The main argument against nuclear energy is that it isn't safe．For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years．And even before Fukushima, there were several high-profile nuclear disasters．The most famous is probably the 1986 Chernobyl disaster, in the Ukraine．The radiation from the meltdown spread all over Europe, affecting thousands．

　　The nuclear energy issue is very complex．And it doesn't look like it'll be resolved anytime soon．As a Japanese commentator recently said, “it's been a bad year for the ‘nuclear village’, but I don't think they’re down and out yet．” The battle continues．

　　I was telling my boy Sonny the story of the hare and the tortoise．At the end I said, “Son, remember： Slow and steady wins the race．Don't you think there's something to

　　learn from the tortoise? ” He opened his eyes wide．“Do you mean next time when I'm entering the 60-metre race I should wish Billy and Tony and Sandy would all fall asleep halfway? ”

　　I was surprised．“But the tortoise didn't wish the hare would fall asleep．”

　　“He must have wished that, ” Sonny said, “Otherwise how could he be so stupid as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did．”

　　“He didn't have such a wish．” I insisted．“He won the race by perseverance(毅力), by pushing on steadily．”

　　Sonny thought for a while．“That's a lie, ” he said．“He won the race because he was lucky．If the hare hadn't happened to fall asleep, the tortoise would never have won the race．He could be as steady as you like, or a hundred times steadier, but he'd never have won the race! That's for sure．”

　　People who eat at home most of the time have better nutrition than those who go out to eat, a recent study shows．Cornell University professors Lana Hall and Karen Bunch interviewed(面试，接见)3900 people in the survey．“People who eat less than 30 percent of their food away from home eat the most nutritiously, ” they said．

　　“In general, Americans don't have nutrient, except for iron and calcium, ” they reported．They have the opposite problem——over-consumption(过度消耗), especially of fat．

　　The food at many fast food restaurants is often low in vitamins．“People who eat more than 30 percent of total calories away from home eat foods that are generally low in nutrients per calorie, ” the professors said．More calories and enough nutrient intake(吸收)are required to achieve．

　　One of the major health risks(风险)is eating too much fat．The professor found than fat consumption became greater as income(收入)went up．It also went up in houses where the female worked．This is probably because these people eat more highly processed(加工的)foods．

　　The Internet is not perfect．There are many problems with it．

　　The Internet is not organized．There is no one in charge of the Internet．It is sometimes difficult to find what you are looking for．It is also easy to get the wrong information on the “Net”．

　　Some businessmen cheat people on the Internet．Internet thieves can steal credit card numbers．Some advertisers send spam to e-mail boxes．E-mail boxes are often filled with these unwanted advertisements．

　　Illegal businesses can operate on the Internet．These businesses sell X-rated materials, cigarettes and alcohol to teenagers．

　　The Internet has websites with information about making bombs, breaking the law and terrorism．

　　Criminals can fool people, especially children, in chat rooms．They can spread poisonous information and attack new members．

　　The Internet is the greatest advance in communication since human emerged．But it can also like a dark alley in a dangerous part of town．Parents need to set parental controls on their children when they use the Internet．This will keep some of the bad material away from their children．

　　The Internet can be dangerous to computers, too．Some people who have evil intentions enjoy causing problems for other people they don't even know．They create computer viruses．A computer can get virus by downloading a program that has a virus in it．Some virus come by e-mail．

　　A virus can destroy the data a person has saved in computer files．A virus can cause a computer to crash．A virus can also reproduce itself! It can send copies of itself to everyone on a person's e-mail address list．Then these people's will have the same problems and can't work normally!

　　Cheating can happen in a lot of different ways．When people cheat, it's not fair to other people, like the kids who studied for the test or who were the true winners of a game．

　　Many people like the action of cheating．It makes difficult things seem easy, like getting all the right answers on the test．But it doesn't solve the problem of not knowing the material and it won't help on the next test-unless the person cheats again．

　　Some people lose respect for cheaters and think less of them．The cheaters themselves may feel bad because they know they are not really earning that good grade．And, if they get caught cheating, they will be in trouble at school, and maybe at home, too．

　　Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying．Other kids might feel like they can't pass the test without cheating．Even when there seems to be a “good reason” for cheating, cheating isn't a good idea．

　　If you were sick or upset about something the night before and couldn't study, it would be better to talk with the teacher about this．And if you don't have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school．

　　A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions(解决办法)together．Talking about these problems and working them out will feel better than cheating．

　　Parents are a child's first teachers．But some parents never learned from good examples．In New York City, a nonprofit agency called Covenant House tries to help homeless young mothers become good parents．

　　The twelve or so teenagers who live at the shelter attend parenting classes four days a week．The class is called Mommy and Me．Teacher Delores Clemens is a mother of five and a grandmother．She teaches basic skills, like how to give a baby a bath and how to dress a baby depending on the season．

　　She remembers one student who learned from her mother not to pick up a crying baby．The mother said that would only make the child needy and overly demanding．Delores Clemens says, “that's not true．You have to hold your baby! He is crying for a reason．If you never pick him up, he's going to keep crying．Pick your baby up．Cuddle your baby．Hug him! And she started to do that．They just want a little cuddling and a little love．And it works! ”

　　Delores Clemens says her students also learn how to be good mothers by letting themselves be mothered．Around three hundred fifty teenage mothers graduate from Covenant House's Mommy and Me class every year．

　　In class, with her baby son is Natasha．She lived on the streets．She is glad not only for the warmth and shelter of Covenant House．As she told reporter Adam Phillips, she is also glad for the help they offer in seeking a more secure life．

　　The World Health Organization says the United States has forty-one births for every one thousand girls age fifteen to nineteen．That is higher than other developed countries, as well as some developing ones．By comparison, northern neighbor Canada has fourteen births and southern neighbor Mexico has eighty-two．

　　Earlier this month, the Obama Administration called for increased protection of the world's most southern continent, Antarctica．Scientists say climate change and human activity have increasingly led to the melting of massive pieces of Antarctic ice．The disappearance of ice will not only affect wildlife in the area such as seals and penguins．The melting will also cause oceans and seas around the world to rise．

　　This represents a major threat, especially to coastal areas．For example, the ancient city of Venice, Italy has long been threatened by rising sea levels．The situation is made worse by the fact that its ancient buildings, built on a body of water called a lagoon(淡水湖), are slowly sinking．When the city was founded about 1, 600 years ago, the level of the Adriatic Sea was almost two meters lower than it is today．

　　Rising sea levels are not the only threat．The salty water is also destroying Venice's famous buildings and artworks．The Italian government is trying to fix the problem with the construction of a seven-billion-dollar system of moving flood barriers．

　　Climate change is also leading to the melting of ice in other areas, such as Mount Kilimanjaro in northeastern Tanzania．It is the highest point in Africa, measuring almost 6, 000 meters．The mountain supports five vegetation zones and many kinds of animals．

　　The ice glaciers on the mountain are disappearing very quickly．This will have a bad effect on the mountain's ecosystems and on Tanzania's travel industry．Also, a valuable record of thousands of years of weather history will also be lost if the ice melts．Scientists study pieces of glacier to understand weather patterns from thousands of years ago．

　　In the United States, the icy masses in Glacier National Park in Montana may soon completely disappear because of climate change．In 1850, there were an estimated 150 glaciers in the more than 400, 000 hectare park．

　　There are 26 glaciers remaining today．Scientists estimate that the glaciers will be gone by 2030．Warming temperatures are also threatening the many kinds of plants and animals that live in this mountain ecosystem．

　　Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky with no land in sight and you are sailing straight ahead to meet the world．Jesse Martin does not have to imagine：he is living in it．

　　On Dec．7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to become the youngest person to sail alone and nonstop around the world．He sailed south of New Zealand, through the South Pacific, around South America, north on the Atlantic, back south past Africa, through the Indian Ocean and back to Melbourne．

　　Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his parents．Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two years old．They moved close to a rainforest in Cow Bay, about 3500kms north of Melbourne, where they built a small house with no electricity or running water．Jesse grew up at the beach enjoying the outdoors to its fullest．

　　At 14, he sailed for the first time with his father and brother, Beau．It was after this trip that he began to dream about sailing around the world．

　　Jesse's family played an important role．“I was made to believe I could do anything．” he says．Although, he says, there were others that were not so encouraging or supportive, “People that I looked up to, respected and trusted told me I couldn't．Thankfully, I trusted myself．There were people that said that the boat couldn't be ready by the time I had to leave．” However, through perseverance and belief in himself he was able to do what many told him was impossible．

　　On Oct．31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the youngest person to sail around the world alone, nonstop and unassisted．
