【推荐1】If music makes you smart and exercise helps you to think, surely exercising to music can turn you into a person who is better at learning and understanding.

A team of scientists from Ohio State University did experiments on 33 volunteers. They found that persons who exercised while listening to Italian musician Antonio Vivaldi’s The Four Seasons did much better in language ability (能力) tests than without music.

The volunteers said they felt better after exercising with or without the music. But their improvement on the test doubled（加倍) after listening to the music during exercise. “Exercise seems to cause positive changes in the nervous system（神经系统）and have a direct result on learning ability,” said the psychologist Charles Emery. Scientists have found that music can be good for health and education. It helps relieve stress, sadness and nervousness, encourages relaxation or sleep, wakes up the body and improves memory and thoughts.

Psychologists have been using Mozart’s music, especially his violin pieces, to help children with speech disorders（言语能力紊乱). Mozart is often chosen because his music is not only exciting. A study showed students who often exercise to Mozart’s music go on to score higher marks in tests. With important exams drawing near, your parents will not probably allow you to listen to music. But perhaps now you have good reasons to argue with them.

【推荐1】Sandwich was an Englishman. He lived in the 18^th century. Sandwich was rich, but he liked to play cards for money. He often played for 24 hours, and didn't even stop to have his meals. He ordered his servants (仆人) to bring him some meat and bread. He put the meat between the two pieces of bread and held the food in his left hand while he played cards with his right hand. People liked Sandwich’s idea, and from then on they ate bread and meat as Sandwich did.

From the name of the man, Sandwich, we have the word of the food “sandwich” today.

【推荐2】There are three common questions about how to improve our English.

The first question is about real English. Some students say that they want to learn real English. But they don’t know what to do. Watching English films is a good way. When we are tired after studying for a long time, we can watch an English film to relax. While watching it, we can also learn real English at the same time.

The second question is about speaking. Most students feel too shy to talk with foreigners. “Where are you from?” “What do you think of China?” These are both good questions to start a conversation. Before we begin, take a deep breath and smile! Smiling always helps.

The third question is about vocabulary. We want to remember all the new words. The problem is that we write them down but forget them soon. Write eight or ten words on a piece of paper and put it in our bedroom. Try to remember them. Spell the words whenever we see them, and change them every day. There is another way, when you’re shopping, counting the English words or saying the English names for everything you see as much as possible.

【推荐3】①Many people like to pet (抚摸) animals because petting can make the relationship (关系) with their pet better. When you’re feeling blue, petting animals is a good way to make you happier. But how to pet animals? Different animals like different ways.

②Dogs like you to pet their heads, necks and shoulders. If you are petting a strange dog, you should come near to it slowly, get down to its height and hold out a closed fist (拳头) for it to smell. After the dog smells you and its body becomes relaxed (放松的), you can slowly touch around its heads and shoulders.

③Cats like people to pet their heads, chins (下巴) and faces. When you are going to pet a cat, let it come near to you first. Sit down and put your hand out for it to smell. If it wants your gentle touch, it will get close to your body.

④Rabbits like you to pet their heads, shoulders and faces. Rabbits are easily afraid of people. So you should come near to them slowly, sit down on the ground and put out your hand for them to smell. If your rabbit comes near to you, use your hand to lightly pet its head.

⑤Pet birds lightly on the head and don’t touch other areas. Building trust (信任) with birds takes time, so come near to them slowly and watch for their body language. If they like you to pet them, they will keep quiet.

⑥Pets are really lovely animals. Pet and take care of them carefully, and they will bring you a lot of fun.

【推荐1】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 know this. 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.
