Doing "Clean "Exercise

    When you go for a run outside, chances are that you'll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging.

    The word "plogging" is the Swedish phrase" plocka upp"（ pick up） and the English word "Jogging"(running slowly)put together.

    What a plogger needs is a rubbish bag and a pair of gloves to protect your hands. While collecting rubbish, ploggers learn to classify (分类)and deal with it correctly, too.

    Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise, For example, a 30-minute logging burns around 288 calories（卡路里）， compared to 235 calories burned from just jogging.

    So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way? Your body and the environment will thank you.

Dear Mr. Hunt,

    My problem is that I can't get on with my family.{#blank#}1{#/blank#}They fight a lot, and I really don't like it. It's the only communication they have.{#blank#}2{#/blank#} When they argue, it's like a big, black cloud hanging over our home. {#blank#}3{#/blank#}He always refuses to let me watch my favorite TV show. {#blank#}4{#/blank#}I don't think this is fair. At home I always feel lonely and nervous. Is that normal?{#blank#}5{#/blank#} 

Sad and Thirteen

    Why do people cry? Scientists say the body produces tears because they need them. One kind of tears is for the eye, the other is for the heart. They both work as cleaners. If something else like dust(灰尘) gets into your eye, tears also come into the eye to clean it out. If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素) in your body, and at the same time, tears come out with them. If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later.

    In the United States men have heart problems more often than women do. Doctors say heart problems have something to do with the pressures(压力) of living and working now. Perhaps men suffer more from these illnesses because they do not cry enough. They need to cry more.

    In fact, you can find many ways of reducing the pressures to keep fit. Crying is a natural and physical one.

    Don't throw away your old phones. You are actually throwing away real gold! Smartphones have many kinds of useful metals. People can recycle them to make new electronics.

    But many people may not knowthis. In Australia alone there are more than 25 million unused mobile phones lying around, The Sydney Morning Herald reported. The gold in these phones can add up to a value of more than $80 million. There are about 2 billion smartphone users around the world, who change their phone once every 11 months on average. So in China, eighty million old phones come along every year.

    However, it's not easy to get the useful things out of the phones. Smartphones have not only useful things but also harmful materials. Guiyu, a small town in Shantou, Guangdong, is one of the world's biggest dumping grounds for electronic waste, Reuters reported. Many recycling centers in Guiyu simply break the old electronics by hand and don't think about the pollution it causes. It's reported that 81 percent of children in Guiyu are harmed by lead poisoning(铅中毒).

    Veena Sahajwalla, a professor at Australia's University of New South Wales, has made a mini factory. It makes smartphone recycling cleaner and easier. The mini factory is very small and easy to move around. It breaks the phones and automatically(自动地)removes the phone's useful things. That way, humans do not get poisoned.

    Well, have you ever wondered what happens to the old phone after it's no longer yours? A part of your old smartphone could soon be proudly worn around the neck of one of the world's top athletes. Organizers of the 2020 Tokyo Olympics say that medals for the event will be made from recycled phones. They will also be made out of people's thoughts for avoiding waste. They think there is an important message in this for the future.

Billy always loved blueberries. They were his favorite fruit. Today he was going to make juice with his uncle. His uncle liked to make juice out of everything. He made carrot juice, apple juice, vegetable juice, and more juices. He had never made blueberry juice before though!

First, Billy and his uncle went to a blueberry farm. They were each given a basket. They picked for an hour and got several pounds. It was hard work picking the little berries from the trees. Now Billy understood why they were expensive in the store.

Next, they had to wash the fruit. Some of them still had leaves. Those had to be pulled off. Then the bad berries had to be thrown away. They washed the berries and made them air- dry.

After that, they pushed the blueberries through a strainer(过滤器). The strainer caught most of the seeds and skins, and only left a small glass of dark purple juice to them.

When they tasted the juice, it wasn't very sweet. Billy's uncle didn't want to add white sugar(糖) to the juice. It was better to use a naturally sweet juice, like apple juice, pear juice, or grape juice. They use grape juice as a sweetener, because grapes had a similar color to the blueberries.

Finally, they could drink it. It was a lot of work to make juice, but it sure was refreshing!

Do you know this place of interest? It is Guqintai (古琴台) in Hubei. It is in memory of (为了纪念) Yu Boya. 

Yu Boya is good at music and he is famous for (因. . . 而出名) playing the qin. But he is always unhappy because he thinks no one can understand his music. On the night of one Mid-Autumn Festival, Yu is playing the qin on a boat. When he finishes playing it, he hears someone's word, "I can feel high mountains and running water in your music. " It comes from a man, Zhong Ziqi. Yu invites him to the boat, and talks about music with him. He is quite surprised at Zhong's deep understanding, and he thinks Zhong is his "zhi yin". When Zhong leaves the world, Yu breaks his qin. Nobody will understand his music, Yu thinks. 

From then on, when people meet a true friend, they say they meet a "zhi yin".
