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.

    The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters long and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that they are in danger and raises money to save them.
    The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.
    The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to increase the size of panda reserves(自然保护区). Some reserves need to be joined together by planting bamboo between them to make “corridors”. These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look for food. ②People are working very hard to make sure the giant panda does not die out.

   It's important to learn about protecting our environment. Here is a 5R rule for us:
   1. Reduce
   If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste
   2. Reuse
   You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
   3. Recycle
   Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted (融化) and the melted things are made for new coke cans.
   4. Recover
   When you buy a box of apples, there may be a few rotten（腐烂的）apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
   5. Repair
   If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a   “throw-away” society（社会）. But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

    A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers.
    Q: Why is the sky blue?
    A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules (分子) because it has a shorter wavelength , which in turn scatters (使分散) it in different directions. That's why when you look up at the sky, it appears to be blue.
    Q: Why does the moon sometimes appear during the daytime?
    A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit (轨道) around the earth is when it is right between the earth and the sun. That's because its back , which is not lit by the sun, is facing us.
    Q: Where do birds/ honeybees go in winter?
    A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50°F. Instead ,they get together in the lower central area of the hive （蜂巢）and form a ball around their queen. This helps keep both warm enough to survive the cold winter months.

Dear Editor,

I live in a beautiful city. Many visitors come to my city. There are so many colorful peacocks (孔雀)here.

The peacocks mostly (主要）live on the grassland of Dongfeng Square. Visitors can give them food freely. They usually throw food to them, and don't think about at all whether the food is right or not. Some of the peacocks became ill. Some even died after eating the bad food.

I'm sure most of the visitors who throw food to the peacocks really like the birds, but they don't realize that they may be doing any harm.

We should tell the visitors that what they have done is very harmful to the birds, and we also must stop this kind of thing from happening.

Perhaps we can build some small shops beside Dongfeng Square to sell peacock food. For every one of us, it's our duty to give more love to these beautiful birds and to look after them carefully.

Yours,

Sun Yan

Every year on 15th October, over 200 million people around the world take part in Global Handwashing Day. But why do we have a day for something we do all the time? Well, research shows that not enough people often wash their hands with soap. Experts believe that this leads to the deaths of millions of people every year.

Sidibe, a public health expert says soap is the most beautiful invention in public health. Washing your hands with soap can have a huge impact on reducing (减少) the spread of diseases. Handwashing with soap prevents babies from getting ill and keeps children healthy in school.

However, washing hands with soap does not happen as often as you might think. This is partly because there aren't enough resources (资源) in poorer countries, but it's also because for many people, handwashing is simply not part of their everyday life. It's not easy to get people to change habits they learned in early childhood -- but this is what Global Handwashing Day wants to do.

In 2008, the Indian cricket team joined around 100 million Indian schoolchildren in washing their hands to promote (促进) the first ever Global Handwashing Day. Every year since then, many different events have been held around the world. In 2014, Global Handwashing Day was used in the fight against Ebola, a very serious disease, with events held in affected (受感染的) African countries.

Today, local and national leaders continue to use the day to spread the message about the importance of clean hands. The hope is that handwashing becomes a necessary part of people's lives and improves the health of millions around the world.

The movie The Martian (《火星救援》) is very popular among space lovers. It shows an astronaut trying to live on Mars.

Although the idea of living on Mars is great, the reality does not look so good. Mars does not have a friendly atmosphere (大气层) for humans. There is very little oxygen there. And because it is too far away from the sun, it is also very cold there. Sometimes the temperature on Mars can be -133℃. This is much too cold for humans.

However, scientists say it might be possible to live there even without a good atmosphere. Daytime on Mars is almost the same as Earth's. It means there's enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil from Earth. Mars does not have a strong enough atmosphere to stop the radiation (福射) coming from space, which makes it dangerous to grow things in the soil.

The radiation also causes problems for our health. One way to live there is to build homes underground or in the rocks on the planet. This can help humans keep away from the radiation and keep warm.

When could we live on Mars? Scientists are hoping to make it possible to live on Mars. Let's wait and see.
