Think of life as a game in which you are playing with five balls in the air. You name them work, family, health, friends and spirit and you keep all of them in the air. You will soon understand that _____ is a rubber ball. If you drop it, it will bounce (弹跳) back.

But the other four balls, family, health, friends and spirit, are made of _____. If you drop one of these. they will be broken. They will _____ be the same. You must understand that and try to have balance in your life. How?

Don’t look down on your _____ by comparing yourself with others. It is because we are different and each of us is special.

Don’t let other people set _____ for you. Only you know what is best for yourself.

Don’t give up when you still have something to give. _____ is really over until the moment you stop trying.

Don’t be afraid of difficulties. It is by taking chances that we learn how to be _____.

Don’t _____ love out of your life by saying it’s impossible to find. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly; the best way to keep love is to give it wings.

Don’t run through life so fast that you forget not only _____ you’ve been, but also where you are going.

Don’t be afraid to learn. Knowledge is a treasure you can always carry easily.

Don’t use time or words _____. You can’t get them back. Yesterday is history, tomorrow is a mystery, and today is a gift; that’s why we call it “the present”. Life is not a competition, but a trip, step by step.

When we want to tell other people what we think, we can do it with the help of words. We can do it in many other ways. too. Sometimes we move our heads up and down when we want to say “yes”, and we shake our heads when we want to say “no”. Some people can’t hear or speak. They talk with the help of gestures (手势). People from other countries often have to do it if they don’t know your language.

Here is a story. An American was once having his holiday in Italy, but he could not speak Italian. One day he went to a restaurant and sat down at a table. When the waiter came, the American opened his mouth, put his fingers in it and took them out again. In this way he wanted to say “Bring me something to eat”. The waiter soon brought him a cup of tea. The American shook his head and the waiter understood that he didn’t want tea. So he took it away and brought him a glass of milk. The American shook his head again. He was very hungry now and looked sad. He was just going to leave the restaurant when another man came in. When this man saw the waiter, he put his hands on his stomach (胃). In a few minutes there was a large plate of bread and meat on the table in front of him.

Computer companies keep competing to build smaller devices (装置).They are finding new ways to put data (数据) into less space on a memory chip (内存芯片).

______ have been made smaller to fit on to the desktop, smaller again to fit on our laps and again to fit into our shirt pockets (口袋）.

Now, Stuart S.P. Parkin, an IBM researcher, is looking into a new idea in an IBM lab. If it proves successful, electronic devices can hold 10 to 100 times the data in the same amount of space. That means the iPod that today can hold up to 200 hours of video can store every single TV program broadcast (播放) during a week on 120 channels. Parkin thinks he is close to a breakthrough. This can increase the amount of data stored on a chip.

At present the flash drives (闪存卡) business is growing quickly. They are used in digital cameras, cell phones and PCs. Flash drives with multiple (多个) memory chips store up to 64 gigabytes (十亿字节) of data. A single chip is expected to reach about 50 gigabytes in the next five years.

However, flash memory has a problem. Although it can read data quickly, it is very slow at storing it. That has led the industry on a hunt for new storage technologies.

Scientists say Parkin’s new computer memory, called “racetrack memory (赛道内存）”, could begin to replace flash memory in three to five years.
