Too many people want others to be their friends, but they don't give friendship back. That is why some friendships don't last very long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest, be generous(慷慨的), be understanding.

    Honesty is where a good friendship starts. Friends must be able to hones' one another.

    ①如果你不说实话，人们通常都会识破。If a friend finds out that you haven't been hones', you may lose your friend'.

    Generosoity means sharing and sharing makes a friendship grow. You don't have to give your lunch money or your clothes, of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interests. Naturally  you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you ③________.

    Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. ④Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend, you must listen and understand. You must try to put yourself in your friend's place so you can understand the problem better.

    Confidence is very important in daily life. It can help you to develop a healthy attitude. A study shows that the people who are more confident are much happier. They can have more chance to make themselves successful. But how to be more confident? Here are some suggestions:

    Speak loud    When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

    Play sports   Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.

    Encourage yourself    Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

    Get rid of (消除) fear    Fear comes along with failure. But it's easy to overcome (克服) if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

    Pick up a hobby    If you like singing, sing as much as you can. In some ways, a hobby can make you outstanding. And it will make you happy and confident.

    The People's Bank of China will come out the fifth edition(版本)of the renminbi (RMB) from August 30, 2019. These banknotes(纸币)will have brighter colors and new security features(防伪特征).

    We've been using banknotes for around 1,000 years. Back in the Northern Song Dynasty, Chinese people made the worlds earliest paper money to replace(代替) metal coins. These banknotes were called jiaozi.

    Paper money is cheaper to make and easier to carry. These advantages made it more popular than other forms of money. But now, in the digital (数码的)age, paper money seems to be disappearing for the same reason.

    China seems to be heading towards becoming a cashless(不用现金的) society. From supermarkets to street stores, people pay by using the We Chat Wallet and Alipay apps on their mobile phones. Sweden is even closer to a future without paper money. Many Swedish banks no longer even have cash on hand.

    But there are worries about creating cashless societies. Some say it is unfair to the poor and people without much education. It's not easy for them to open bank accounts( 账户)or deal with mobile phones. And if all of your money is" digital, it may not be safe enough.

    Is paper money going away? Although paper money is used less than electronic payment (电子支付) in some countries, it won' t disappear at once in most parts of the world.

    Teeth are a very important part of our bodies. Good teeth help you eat things like apples. They also help you talk. The healthier your teeth are, the happier you will be.

    But before that, you have to pick a good toothbrush. Be sure your toothbrush are soft enough Also, brushes with small heads are better. They can reach every corner of your mouth.

    Now it's time to brush. Brushing helps break down plaque（牙菌斑）Plaque is a kind of bad thing that can make small holes in your teeth. Brush your gums at a 45—degree angle（角度）This works well to clean both the teeth and gums.

    Learn how to floss your teeth. It gets rid of food in the spaces between your teeth. Your toothbrush can't get there. Move floss between each tooth gently back and forth once a day. It may feel a little difficult at first, but pretty soon. You'll be good at it!

    Around the world, people live in homes of many shapes and sizes. In some countryside, people live together with their family in a huge house with gardens or backyards. On the other hand, the buildings in cities are usually very close together.

    A home can be any kind of building—large or small. Some people even have homes on boats, in tents or in caravans that can be moved around. Caravans are mobile homes. They are towed(拖，拉) by either a car or a huge truck. Some of them are holiday homes. We can see many families staying together in these caravans.

    In the past, rich and important people built strong castles to keep their families safe. The castles(城堡) were built on hill tops with high walls and some even had moats. Moats were deep and wide ditches(壕沟) filled with water. They made it difficult for enemies to attack.

    Today, we have different ways of protecting our homes. Some homes are installed(安装) with video cameras and an alarm system. These will help to alert(向……报警) home owners if someone tries to break in.

    Homes are important to all the people. Everyone needs a home where they feel sheltered and safe.
