In your schoolbags, you may have a pencil, some kinds of pens, a ruler, and some books. None of these things grow in the fields. They were all made in factories. And, of course, they were invented by some people. There have not always been pencils or pens, a ruler and books. Thousands of years ago no one knew about these things.
Who invented them first? How did they have such clever ideas? We always don't know. There have been many thousands of inventions, large and small, in the human history. Some of these inventions have changed the world. Such as paper, printing, radio, telephone and computer, and we know the inventors. But we have forgotten most of the other inventors.
Who invented the clock, for example, or the lock to the door? We don't know. There have been thousands of inventors and we should grateful（感激的）to them for their clever ideas. Will you be one of them when you grow up?
It's always a happy moment when you get some pocket money（零花钱）. But have you ever thought about how to spend your pocket money wisely? Here is some advice.
Make a list.
When you get your pocket money, don't get too excited. We all have a lot of things that we want. But do you really need them? That's why it is necessary to make a list before you spend money. Start with the thing you want most. You can also write down how much it costs or how important it is in your life. By doing this, you will see if it is really necessary to buy it.
Help others.
How about being more selfless（无私的）and using your pocket money to help others? We all know that there are many people in the world who are in need of our help. Helping others brings out the best in us and is one of the greatest joys in our lives. So consider using your pocket money to do something useful and helpful, and feel how you can make a difference.
Save（储蓄）as much as you can.
There is an old saying "Money doesn't grow on trees" If you spend all your pocket money right away, you'll have no money until next "pay day". A wallet sometimes might not be the best place to save money because it may make it easier for you to spend your money. Get a piggy bank（储蓄罐）or ask your parents to start a savings account（账户）for you. Someday when you look back, you'll get a strong felling of achievement by saving so much money by yourself!
Animals can live in many different places. Some animals dig holes and live underground. Their homes may have just one room. But some have many rooms. And sometimes an underground home has more than one entrance. Foxes and rabbits live in this kind of home. Birds build their homes. Some birds build their nests in trees. Others make them on the ground. Birds in cities may build their nests on buildings.
Other animals besides birds make nests. Some snakes and turtles make nests. Some squirrels do too. You can sometimes see a squirrel nest high in a tree. Some spiders make webs to live in. They also catch their food in their webs. Other animals don't build or dig their homes. They survive by finding places to live in. Animal homes are very interesting.
Fights at school sometimes happen. But how can you keep away from a fight? Here's something you can do.
Be calm. Sometimes, you feel so angry that you really want to teach somebody a lesson. But being angry can't solve problems. Neither can a fight. Instead, it may bring you more problems. In the school, everyone involved in a fight will be punished, no matter who started it. There are no winners in a fight.
Shout loudly. If you know someone is coming up behind you to attack, turn toward the person with your hands up in front of your body and loudly say "stop" before walking away. A loud voice can usually make the attacker calm down. If the person doesn't stop, cry for help by calling out the name of a teacher whose office is nearby.
▲▲ Your friend may ask you to join in a fight. Learn to say no. Helping him fight is not really helpful to him. If you really want to give him a hand, try to ask him to give it up. Also, you can tell him if he gets involved in a fight, he may get hurt and be punished. Then, try to learn why he wants a fight and help him find a right way to deal with the problem.
