The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans 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 memory 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. Say “__________________”

    Break a big number into smaller parts. For example, it's hard to memorize 109244153. But if you break it into three parts—109/244/153—it becomes easier.

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

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

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

    Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.

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

    Life in the year 3044 is very different 1  life in the 21st century. We still do many of the things you do, but we do them 2  For example, we now have e-friends to help us and company us. An e-friend is a machine that looks just 3 a human being. It can walk and talk and can do almost 4 we human beings do. My e- friend is a lot like me and we have 5 fun together. She helps me 6 my homework and we often go swimming. She is programmed to take care of me if anything 7, so I always feel safe when we are together.  She can also send me messages, just like old-fashioned emails, and I can download information from her memory. It's great  8an e-friend--I am never lonely and I always have someone to talk 9.

    I would like to tell you more about life in the year 3044, but I have to send my e-friend to clean up my room. Maybe 10 I will be able to travel back in time and visit you.
