Everyone has worries. How do you deal with (处理) your worries? There is always something you can do to help yourself feel less worried. Sitting there worrying is no use and it can’t solve your problems. Grades at school are often a top worry for kids. If you worry most about grades, ask yourself these questions:

◆Why are grades important? What do grades mean to me?

◆How do I get ready for class? Do I go over (复习) my notes even when there isn’t a test?

◆Have I tried different ways of studying?

If your worry is about a fight with your friend, you might write down all the things you could do—write a note to him or her, invite him or her to watch a basketball game, say sorry to him or her and so on. Once you have a list of things to do, you could choose one thing that may get your friend back.

You can ask for help when you’re worried. You can find someone to talk to, such as your parents, friends and teachers.

The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between human brains and computers. Computers don't forget information they are given, but humans often do. No one remembers everything and luckily we don't usually have to. But everyone can improve their memories if they want to. Here are some suggestions.

Try to use new information immediately. For example, if you meet someone who says " Hi! I'm Carlos. " Don't just say "hello". Repeat the person's name and say "Hello, Carlos”

Break a big number into small parts. For example, it's hard to remember 109244153. But if you break it into three parts-109/244/153, it will become easier.

Write down what you need to remember over and over again. This will help you keep it in mind longer, especially when memorizing formulas（公式）or facts.

Always review information. If you bring what you've learned back to your mind, it'll become easier to remember. For example, before you go to sleep, it's a good idea to, the new things you've learned that day.

Discuss with friends. It is always easier to remember things through discussions. You can have a discussion about what's right or wrong, and it will lead to the right answer.

All of the suggestions are helpful. If you follow them, you am certain to improve your memory.
