Do equations and historical( 历史的) facts give you a headache? A change in the school timetable(课程表) may be the cure.

    This  suggestion  is  based  on  a  recent  study  carried  out  by  scientists  from  Royal  Holloway, University of London, the UK. They found that teenagers could get higher marks in math if they studied in the mornings and better grades in history if they were taught in the afternoons.

    The researchers studied students' grade reports, class timetables and absence rates( 缺席率) at a middle school in Bulgaria over nine years. The results showed that when teenagers had math classes earlier in the day, they scored about 7 percent higher in tests than when taught in the afternoon. Lower-ability students feel stressed most when they were studying math in the afternoon. In history, students taught in the afternoon scored about 6 percent higher than when they were taught in the morning. However, there was no sign that similar patterns( 模 式 ) work for other subjects such as languages or geography.

    Velichka Dimitrova, who did the study, said the findings show that we perform( 表 现 ) better at different times of the day. “In the morning, our brains are better and fresher, so we are better at doing something like problem solving, where we require more speed and attention” Dimitrova told The Telegraph. “In the afternoon, it seems that this process slows down. On the other hand, history is more suitable for the afternoon, when we are more creative and open to discussion,” she said. Subjects such as foreign languages require both memory and creativity. This is perhaps why the time of day had no influence on language learning.

    Time-of-day influences such as these are believed to have something to do with the body clock.

    This is the system in our bodies that controls when we need to sleep. Some schools in the US and UK have tried later school starting times for teenagers, whose body clocks change as they grow into adults. Dimitrova believes schools should jump at this chance to improve their students' performance just by changing their timetables.

    We all need a healthy environment, but we produce waste every day and it is harmful to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live a green life.

    Remember these three words; reduce, reuse and recycle.

    Reduce means" use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy thing, choose local products if possible, and try not to buy too many things from abroad.

    Reuse mean" use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup(瓷杯) and a lunch box because you can use them again.

    Recycle means" change things into something else". Although it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

Beijing Opera is one of the Chinese traditional drama art forms and the largest Chinese opera form. Having a history of about 200 years, it is developed from many other drama forms, mostly from the local drama" Huiban". It was especially popular in south China during the 18th century.

Theatrical(戏剧的) art forms in many other countries do not have singing, dancing and spoken parts together in one single drama. An opera singer, for example, neither dances nor speaks on stage; there are no singing or dancing parts in a modern play; in a dance drama, the dancer doesn't speak or sing. Traditional Chinese drama, including Beijing Opera, is a kind of entertainment(娱乐). It includes spoken parts, singing and dancing.

Beijing Opera has spread to many other places. Mei Lanfang, one of the most famous performers of all, was the first to introduce Beijing Opera to foreigners and made highly successful tours to foreign countries." You will doubt and sometimes be a little bored, but you will be interested gradually. You will be strongly attracted to Beijing Opera, even if you know nothing about the drama background." This is how one traveler described his first experience in watching Beijing Opera.

Beijing Opera is China's national opera and it is full of Chinese cultural traditions. Welcome to China and enjoy Beijing Opera!

Sit back and get relaxed!

These days, we easily feel stressed as we get more and more work to do. It's important to know how to solve problems and find ways to relax. 

First, we should try organizing our work from most important to least important as well as most urgent(紧急的) to least urgent. {#blank#}1{#/blank#} As soon as those are done, work on things that are important but not urgent. Then, do things that are less important and less urgent. This makes us know what to do first and not worry about the rest. 

Still, sometimes we feel stressed even after organizing our work. That's okay. {#blank#}2{#/blank#} Because exercise helps a lot in forgetting about our problems. It doesn't even have to be a big trip to the gym, although that surely helps. It could be something as small as walking around the neighborhood for 10 to 20 minutes. 

Finally, we can try meditation(冥想). {#blank#}3{#/blank#} Just set aside 10 to 20 minutes with an alarm clock, sit straight, close our eyes, and focus only on breathing. If other thoughts come up, accept that they are there and let them fly away on their own. {#blank#}4{#/blank#}

By trying these steps, we will certainly feel peaceful when finishing all of the work. 

Which way is better for you to get relaxed? Why?( about 20 words) {#blank#}5{#/blank#}
