Mrs. Green is telling her experience：

The brain is the most amazing part of our bodies．But just like our bodies，it needs care．Getting a good night's sleep．eating a balanced diet（均衡飲食）and taking deep breaths are all important ways of looking after both your body and your brain.

Many people think their brain will slow down with age and their memory will get worse．The truth is，just like your body，you can also improve your brain．I've found I can improve my memory by picturing what I need to remember．For example，if I'm going shopping and I need bread milk and a birthday card for my brother，I picture a loaf of bread，a bottle of milk with a cow in the front and a birthday card with a football on it．

The same kind of thing can be used with important dates．If you have a picture in your mind of a special event（事件），it's much easier to remember than just a number．

Another way of improving your mind is to make sure you often visit new places and have new experiences．I find learning Spanish is a great way to keep the brain working，but communication in any language is important．

    B．She finds dates more difficult to remember than numbers．

    C．It has got worse over the years．

    B．The latest research into the brain

Arbor Day All over the World

All Over the world，people are planting trees，caring for them, and learning about their value．A special day was set aside for planting trees．

Computer games are very popular．It is natural to want to win，so playing against a computer or against a friend on the computer can be difficult to stop “Just one more game，”often ruins into another game then another．

    Computer games do have their advantages．They are excellent for training． hand-eye coordination（協(xié)調(diào)）．Surgeons（外科醫(yī)生）today who played computer games as children are often more skilled than those who didn't．Computer games can also be great for teaching students．The students are open to learning while playing and can study for longer than a teacher would be able to teach．Students can also learn at their own speed and not feel pressured（有壓力的）to match classmates．And practice makes perfect．

    But like anything else in life，things should be balanced．Too much time on the computer can hurl．your eyes．Regular breaks（間歇）are needed．If students cannot stop playing computer games，they won't do as well in other areas in their life-not just schoolwork，but in developing important social skills such as how to talk with people and how to work with others as part of a team．And if they aren't taking regular exercise their health will suffer（受苦）．
