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 (记忆) 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.

“Green” is more than just a color. It also means taking special steps to protect the environment—the water, the land, and the air we breathe. Why green? Plants are green, and without them the earth wouldn’t be such a lovely home for us human beings.

Every day, people make choices that affect the amount of trash and pollution that gets produced in our world. What can you do? A whole lot, actually. Here’s a four-step guide to being green:

Reduce the amount of stuff you use and throw away.

Reuse stuff when you can.

Recycle cans, bottles, paper, books, and even toys, Sometimes water can be. For instance, some communities take used water – like from the washing machine and shower – and clean it up so it’s safe to use for watering the grass and flowers.

Enjoy the Earth – walk in the woods, plant a tree, and eat some of the delicious food it produces.

Here’s a list of other stuff you can reduce:

Close the switches when you’re not using lights.
