As we all know, sleep is very important and necessary. I would love everyone to develop the following four habits to have better sleep without needing the alarm（闹钟）wake-up call.

    {#blank#}1{#/blank#}If you eat much food an hour before you go to bed, your body will hate you, because your body needs time to digest while you are still awake.

    {#blank#}2{#/blank#}When I hear on TV that people just need 30-minute exercise a week, I think that's wrong. Every person should get 30-minute exercise every day. When you exercise, your body uses energy and feels tired. You have to recover from the tiredness. {#blank#}3{#/blank#} The harder you exercise your body, the faster it falls to sleep and the better it sleeps.

    Turn the TV off. There are a few shows I still watch, but they will never get in my way of (妨碍) sleep. The bedroom is only for sleeping and rest. {#blank#}4{#/blank#}.

    {#blank#}5{#/blank#}A question to ask yourself: If I didn't have an alarm, what time would I get up? If that time is the time you need to get up, you should probably throw away the alarm. If the time you actually get up is much later than the time you need to get up, make great changes to your way of life and the time you go to sleep. No one should need an alarm.

A. Exercise for at least 30 minutes every day.

B. Don't eat any food 4 hours before you sleep.

C. Throw away the alarm.

D. Sleep is one of the most important things in our lives.

E. Your body recovers when you are sleeping.

F. Try to get up as early as you can.

G. Take the TV out of your bedroom.

    When I was in the fifth grade and Mr. Gardner asked a question, my hand would often shoot up in enthusiasm. After giving me a few opportunities, he would try to give other students a chance. My hand, though, would remain in the air, and after some time, I'd start waving it around. Then, there was the time I entered drumming classes. But all we were allowed to do in the first class was practice one beat over and over again. I never went back.

    I would have done terribly in the Stanford Marshmallow(果浆软糖) Experiment. In this classic study, researchers gave children a choice between one marshmallow right away and two later. The results showed that those who could wait 15 minutes ended up scoring 210 points higher on the SAT, an examination that American high school students take before they go to college.

    So clearly, delaying(延迟的) gratification or bearing up under pain have their benefits. It needs patience, which keeps us from being stuck to ideas formed previously, and helps us let go of our strong desire for consequences. We come to accept that we don't always or immediately know what is best, and learn to recognize that our reality is in constant changes. Patience improves our understanding of deeper truths and helps us expand our views.

    The journey of patience is rooted in knowing that our present reality will finally give way to changes. But changes won't always happen when we think they should, and patience with ourselves comes from accepting that there are things we can control and things we can't. And though we must make great efforts to keep pushing the boundaries of our awareness and to improve our ability to rest in comfort in the present moment, how fast we develop isn't up to us.

    That same fifth grader who couldn't wait to speak out answers now sees the value of meeting questions with a heart of patience.

    Gravity signals that race through the ground at the speed of light could help seismologists(地震学家) get a better handle on the size of large, destructive quakes soon after they hit，a study suggests. The tiny changes in Earth's gravitational field, created when the ground shifts, arrive at earthquake monitoring stations well before earthquake waves.

    “The good thing we can do with these signals is have quick information on the magnitude (震级) of the quake,” says Martin Vaillée, a seismologist at the Paris Institute of Earth Physics.

    Earthquake equipment in China and South Korea picked up gravity signals immediately after the magnitude-9. 1 Tohoku earthquake that destroyed parts of Japan in 2011. The signals appear as tiny accelerations on earthquake-recording equipment, more than a minute before the seismic waves show up.

    “We can look before the earthquake waves arrive,” says Vallée. “If we see nothing, we can say that the quake that made these was maybe large, but not huge. If we see the signals, it means we really have a very big quake. ”

    Had seismologists been monitoring for gravity changes, they might have realized sooner just how big the Tohoku earthquake was. A small increase in an earthquake's magnitude means a large change in the energy released by the quake-and the destruction expected. That information is important for emergency responders as they decide what resources to arrange.

    It'll be a major contribution if gravitational waves can beat down the time needed to know that a big earthquake is big. But much work remains before gravity signals can be considered a reliable tool in the vital minutes after a big quake. A few extra minutes of warning can save lives, particularly in coastal areas where people can flee ahead of an incoming tsunami.

    Cooperation at work is generally seen as a good thing. The latest survey by the Financial Times of what employers want from MBA graduates found that the ability to work with a wide variety of people was what managers wanted most. But managers always have to balance the benefits of teamwork, which help ensure that everyone is working towards the same goal, with the dangers of “groupthink” when critics are reluctant to point out a plan's drawbacks for fear of being kept out of the group. The disastrous Bay of Pigs invasion of Cuba in 1961 was a classic case of groupthink. Skeptics were reluctant to challenge John F. Kennedy, the newly elected American president.

    Modern communication methods mean that cooperation is more frequent. Workers are constantly in touch with each other via e-mail messaging groups or mobile calls. But does that improve, or lower performance? A new study by three American academics, tried to answer this question. They set a logical problem (designing the shortest route for a travelling salesman visiting various cities). Three groups were involved: one where subjects acted independently; another where they saw the solutions posted by team members at every stage; and a third where they were kept informed of each other's views only intermittently.

    The survey found that members of the individualist group reached the premier solution more often than the constant cooperators but had a poorer average result. The intermittent cooperators found the right result as often as the individualists, and got a better average solution. When it comes to ideal generation, giving people a bit of space to a solution seems to be a good idea. Occasional cooperation can be a big help: most people have benefited from a colleague's brainwave or (just as often) wise advice to avoid a particular course of action.

    Further clues come from a book, Superminds, by Thomas Malone of the Massachusetts Institute of Technology. He says that three factors determine the collective intelligence of cooperating groups: social intelligence (how good people were at rating the emotional states of others); the extent to which members took part equally in conversation (the more equal, the better); and the cooperation of women in the group (the higher, the better). Groups ranked highly in these areas cooperated far better than others.

    In short, cooperation may be a useful tool but it doesn't work in every situation.

    The world is a truly strange place waiting to be explored. In addition to offering a lot of extraordinary locations and people, it also offers interesting festivals celebrated by people in various parts of the world. Here is a list of the oddest festivals that can be found around the world.

    Cheese Rolling Festival: A festival that is surely going to leave you with a sore neck if not a broken one! Celebrated in England, the Cheese Rolling Festival is something that you would rather watch than take part in.

    Okay! Here's how it goes. Officials set a big cheese wheel to roll down a steep hill and participants run after it. The first one to catch it wins the competition and the cheese. Simple? Well, try it out and you will know!

    The Monkey Buffet: Now here's a country that actually feeds monkeys to their hearts' content instead of chasing them away. Celebrated in Thailand, the Monkey Buffet is an annual event that brings together a lot of locals who offer fruit and vegetables to over 600 monkeys. It's a great feast as the monkeys dig into almost 3, 000 kilograms of fruit and vegetables. The people of Thailand believe this is a way to honor the Monkey King called Hanuman.

    La Tomatina: Here's your golden chance to get even with your friends who sprayed(喷洒)paint on you on your birthday. Celebrated in Spain, the month of August has nearly 250 pounds of tomatoes go down the drain(被浪费掉)in what is perhaps the largest tomato fight in the world. The event is conducted in the town of Bunyol and attracts nearly 30, 000 tourists around the world in addition to locals. Truckloads of tomatoes arrive and you are ready to go. The entire area is covered with slush and tomatoes within minutes. It's a good time to have fun with friends and family.

    UK education is all about giving you inspiration to develop your knowledge and skills, freedom to be creative, and support to help you achieve your best.

    On a UK course you will benefit from excellent teaching and facilities. In order to accept students, UK education centres must meet strict quality standards set by the UK government and education bodies.

    With such a good reputation for research and education, universities and colleges in the UK attract some of the world's leading academics and professionals. You will be encouraged to express your own ideas and think for yourself.

    The attention to quality is reflected in the UK's excellent results:

    Four of the top six universities in the world are in the UK.

    The UK is a world-leading research nation. 54% of the research conducted by UK universities and colleges is classed as either "world-leading" or "internationally excellent".

    At the most recent inspection, 97% of further education colleges were judged satisfactory or better, for their overall effectiveness.

    In the recent BIS Tracking International Graduate Outcomes survey, more than 88% of international higher education graduates said they were satisfied with their UK learning experience.

    Likewise, in the Higher Education Academy Postgraduate Taught Experience Survey of UK postgraduate students, 93% rated the quality of teaching positively.

    For English language students, you'll find the UK has long been at the forefront of language teaching, and pioneered many of the techniques now used around the world. The emphasis is on learning the language through fun and participation: Instead of just listening to your teacher, your classes will involve games, problem-solving and discussions. You might also listen to songs, watch television or read magazines to practise your comprehension skills.

    The UK's boarding schools also offer excellent teaching, facilities and support. At UK independent schools (most boarding schools are independent), a teacher has just 9.4 pupils on average, so teachers have more time to give you individual support. This is reflected in the results: 91% of students from UK independent schools go on to higher education.
