A private sixth grade is set to start its lessons at 1.30 pm every day because the school's teacher thinks his students will study better after a morning lie-in (懒觉).

    Instead of rising early for a 9 am start, students at the ￡15,000-a-year Hampton Court House, in East Molesey, Surrey, will get to enjoy a lie-in and work from 1.30 pm until 7pm. Head teacher Guy Holloway says the move for all sixth grade students, set to begin from September, has been made according to research by scientists. He predicts (预测) that not only will his students aged 16 and upwards get great night's sleep, but their productivity (效率) will also be improved.

    The co-educational school will have the latest start time in the UK, and will be the only one to begin lessons in the afternoon.

    Experts say young people are programmed to get up later, and that rather than laziness it is simply a shift (转变) in their body clocks.

    There are 168 hours in a week and how productive they are depends on how they choose to use those hours,' said Mr Holloway. 'At Hampton Court House we don't think we have the answer for everybody; it's about what works in our school. We want to get them into a condition where they can get great sleep and study well.' He said students would also benefit from reduced journey times as they travel to and from school after rush hour (上下班高峰时间).

    Year 10 student Gabriel Purcell-Davis will be one of the first of 30 A-level students to start at the later time. 'I want to wake up in my bed, not in my maths lesson,' said the 15-year-old. Lessons for all other students at the school will still begin at 9 am as usual.

    What do butterflies have in common with the human spirit? Meet Maggie, a middle-aged wife and mother who was about to find out.

    Maggie wasn't rich like a millionaire or poor in a manner of being homeless. She was living an average comfortable life. It was made even better when a baby girl came her way. She and her husband made sure their daughter had her needs met and they were still able to take a yearly vacation by the beach.

    Maggie was a partner in her husband's business. They both had a different set of duties and everything was in balance. One day a severe blow came to her husband's business, and over a three-year period the business dropped out of sight. Her husband had to totally reinvent himself and was eager to start a new business. She was happy for him and supported him fully, but still the money was not coming in.

    Maggie began to feel guilty that she wasn't contributing with any kind of income. She began job-hunting and found filling out applications somewhat difficult, especially the part asking for job references. She was self-employed with her husband for almost 20 years, which seemed to mean nothing as she was never called for an interview.

    When she was job-hunting her mom became more ill than she had been and ended up in the hospital for a week. Once Maggie's mom returned home she became her mom's helper one day a week. She did everything that her mother was not able to do any more. Of course her mom would pay her for her lime and labor but she still felt she needed to find another source of income.

    One of the first applications she had filled out finally came through. She passed the interview and was told she was exactly what they were looking for. Although it was only part-time it was exactly what she wanted. It was important for her to be home when her daughter arrived home from school.

    Within a few weeks, though, she received an e-mail saying that the company had changed the job into a full-time position so that she was not qualified. Maggie felt betrayed and felt she had been lied to. That evening she was alone at home. She welcomed the aloneness and wanted to put herself in the bathtub to kill the lonely time.

    As she knew she would, Maggie began to cry, softly at first just from the sharp pain of being rejected. Three long years of struggle had finally overwhelmed her.

    When she was able to cry no more, she became worn out and gave up. It was at that moment that a silent idea came to her: why not offer elderly people home care assistance? Using another talent for computers she printed off some flyers and cards and distributed them to her church, grocery stores and even placed a small ad in the newspaper. Within a week she had procured two new customers. Now, even though she's not a CEO of a major company she feels happy and productive again.

    Before a butterfly can come out of its chrysalis (茧) it has to go through a lot of struggling. Each time it pushes out to escape, acids are being removed from its wings. If someone were to come along and break the chrysalis open for it then the butterfly would die from those acids. Actually the struggle is necessary for the butterfly to survive. Then in the stillness, when the struggle is over, the butterfly can come out and share its beauty with the world.

    We as humans are not any different.

    Last month, the president of the Maldives, Mohamed Nasheed, held an underwater meeting. The purpose of the ocean floor conference is to highlight the effects of global warming on his island nation.

    The Maldives, located in the Indian Ocean, is the lowest-lying country on Earth. Melting glaciers and polar ice are causing sea levels to rise, putting the Maldives and other low-lying areas at risk of being swallowed by the sea within the next 100 years.

    What can be done? Scientists and leaders from 190 nations will try to figure that out at the United Nations climate change conference next month. The main goal of the meeting is to come up with a new climate agreement for 2012 and beyond. That is when the existing plan, the Kyoto Protocol will expire. The agreement was created in Kyoto, Japan, in 1997. Since then, it has been ratified(正式批准) by 190 nations. The countries promised to limit the amount of greenhouse gases, such as carbon dioxide, which they produced each year.

    The debate over who should cut greenhouse emissions has been going on for years. The US has been hesitant to reduce emissions unless fast-growing nations such as China and India also reduce their use of fossil fuels. In recent months, China has taken steps to be greener. But India has been unwilling to change. It argues that it is unfair for rich nations to ask poorer countries to cut down on emissions.

    While world leaders work on a plan in Copenhagen, there are many things you can do to help the planet. You can save fuel by walking or biking instead of riding in a car. You can start a recycling program in your community. You can plant trees. Trees absorb carbon dioxide from the air and give off oxygen.

    Back in 1988, Red Delicious made up 70 to 80 percent of the domestic apple market. Over the years, farmers sold a lot of them because they looked great. But they had a floury texture (质地), and people want an apple that's firm, crisp(脆的)and juicy. I started searching for one. By 1994, threatened by varieties from Japan and New Zealand, the U.S. apple industry and Washington State University agreed that we had to grow our own.

    First, we cross-pollinated(授粉) existing apples: Collect pollen from one flower, put it on the tip of a pencil eraser, and rub it into another. We crossed dozens of crisp, tasty varieties such as Gala, Fuji, and Pink Lady. But the best breed came out of Honey Crisp and Enterprise parents. We grew the cross-bred seeds into 5-foot trees, grafted those to rootstocks(根茎) to make them start producing quickly, and planted them in evaluation gardens. A few years later, they fruited—and we began tasting.

    So I would walk down long rows of hundreds and thousands of trees, and when I found an attractive fruit, I'd bite, chew, spit it out. Most were terrible, but when I found one with good texture and taste, I'd pick 10 or 20 of them. Then I put them in cold storage to see how they would hold up after a few months. After that, three or four researchers sat down and tasted every apple. We checked acidity and sugar levels, which can break down over time, and tested firmness and crispness using instruments that measure pressure and cell breakdown.

    When we found exactly what we wanted, we planted and tested them all over again. Eventually, we ended up with the Cosmic Crisp. It can spend nine to 12 months in storage, and stay crisp, firm, juicy and sweet.

    Nowadays, top performing sportsmen earn huge amount of money as compared to people in other professions. Some people consider it a rational approach. However, there are a few who think it is unjustifiable.

    Some people think sports professionals with outstanding performance should be overpaid as it is a short-lived career which requires rigorous hard work as compared to other professions. This field demands a strict, disciplined life with extensive physical efforts, consistent practice, a fixed diet schedule to bring pride and glory to the country. Due to such tough requirements, people in this field have an average career span of 10-15 years. As sports professionals have limited tenure, they should be rewarded with high monetary gains to acknowledge their excellent performance.

    However, there are a few who think that top performing sportsmen and women should not have high salaries as it is a biased approach. They feel that there are other critical professions which are more valuable to the country as compared to the sports field. For example, the professions, like doctors, social worker, works for the betterment of the society. Their efforts not only help to reduce the social issues prevailing in the community, but they also contribute in providing a healthy environment. As a result, they significantly contribute to the growth of the country. Henceforth, their efforts should be equally recognized along with the sports professionals.

    In my opinion, although there are some logical reasons for huge earnings of the top performing players, people from other professions should also be equally appreciated in terms of lucrative monetary benefits for their outstanding contribution. As all the professions are critical in their own field and contributes to the overall development of the country.

    To conclude, sports people delivering excellent performance should not be overpaid in comparison to other professionals who make a significant contribution to the society.

    It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name "hackers".

    Police arrested a few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades.

    As hackers gained experience, they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline's computer to give him free airplane tickets.

    The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into.

    In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime.

    The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.

    The U.S. government believes foreign governments have hired hackers to try to break into top-secret defense computers.

    Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most outstanding minds in the U.S. will be working to frustrate the attempts of computer hackers.
