Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.

According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. Andtheseare just the things that we can see from the surface of the earth by telescopes. There are also millions of smaller pieces of junk that we can't see.

Objects, like bits of old space rockets or satellites(卫星), move around the planet at very high speeds fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (轨道) .

To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

Many scientists also suggest different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space Researcher.

"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

Do you know what family instructions are? They are common beliefs that family members follow. In ancient China, people passed down their family instructions from generation to generation.

Some schools in Zhejiang are encouraging students to learn more about their own family instructions. At Hangzhou Gongyi Middle School and Hangzhou Xuejun High School, it was part of students' winter vacation homework to learn about their family instructions.

Meng Yaohan, 16, from Hangzhou Xuejun High School, looked at her family instructions. One of them is "Don't take the wrong way", a piece of advice that has been passed down for 100 years. Her father told her how her grandfather stuck to his "right way" to become an engineer. "It encouraged me to pursue what I love," she said.

Shen Duanjie, 14, from Hangzhou Gongyi Middle School, has got good from his family instructions"— democratic" (民主的) and "equal". In his own words, they have helped him get along with his parents.

The school has also published books about two classic collections of family instructions—The Family Instructions of Zhu Xi and Family Instructions of Yan Clan. The books include dialogues and pictures drawn by students.

Gong Zhenyue, 14, drew pictures for one of the instructions in Family Instructions of Yan Clan. She was impressed by the instruction, which says that parents should not only love their children, but also educate them. "It made me understand my parents' strictness with me," she said. She made it her own family instruction.

If you argue with your friend, will you forgive him or her? Most people prefer to forgive others, according to the Daily Mail.

Researchers from Yale University, the University of Oxford and University College London have found that we tend to (倾向于) believe that people are good at heart, even when they have behaved badly. .

. The strangers were told that they would receive money if they shocked another person with electricity. The "good" stranger refused the deal and the "bad" one accepted it.

The participants were then asked to judge (评价) the strangers based on their decisions. . But they were not confident that the "bad" stranger was truly bad. If they then saw the bad person do something good, they were more likely to have a positive impression of him or her.. In addition, people are more likely to believe someone is innocent (无辜的), rather than guilty.

This tendency can help us develop and keep healthy social relationships. Sometimes, people behave badly by accident. . But what happens if it is found later that this person is not truly bad? We may have lost a good friend or partner, Molly Crockett from Yale University told the Daily Mai.

A. Scientists believe that it is human nature to see the best in others.

B. Forgiving someone is the best way to build healthy relationships.

C. But we might get a bad impression of them anyway and therefore end our relationship with them.

D. And when these "bad people" do something nice, people will be likely to forgive their previous (之前的) mistakes and have a positive opinion of them.

E. They reported having a positive impression of the "good" stranger.

F. In an experiment, more than 1,500 participants (参与者) were asked to watch two strangers.

World Sleep Day, observed on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world don't realize it's important. As a result, sleep problems are increasingly common.

In 2011, scientists at the University of Athens in Greece did a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Among the people, 24 percent said that they did not sleep well. 31.6 percent were diagnosed(诊断) with insomnia (失眠). In addition, 30.7 percent of them have visited doctors for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

The survey found that many people suffer the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also affect sleep and cause poor quality sleep. The survey's findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short-term effects of this are tiredness and trouble concentrating(专心). If this happens for a long time, the risk of putting on weight and having a heart attack may increase.

There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.

Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.
