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 (精神) and you keep all of them in the air. You will soon understand that work is a rubber ball. If you drop it, it will jump back.
But the other four balls, family, health, friends and spirit are made of glass. If you drop one of these, they will be broken. They will never be the same. You must understand that and try to have the balance in your life. How?
Don’t look down on your worth by comparing yourself with others. It is because we are different and each of us is special.
Don’t let other people set goals for you. Only you know what is best for yourself.
Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.
Don’t be afraid of difficulties. We learn how to be brave by taking chances.
Don’t shut love out of your life by saying it’s impossible. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly (紧紧地); the best way to keep love is to give it wings.
Don’t run through life so fast that you forget not only where you’ve been, but also where you are going.
Don’t be afraid to learn. Knowledge is a treasure (珍宝) you can always carry easily.
Don’t use time or words carelessly. You can’t get them back. Yesterday is history, tomorrow is a mystery (秘密), and today is a gift; that’s why we call it “the present”. Life is not a competition, but a trip, step by step.
【小题1】The passage tells us not to _________ because everyone is special.

You hurry into the kitchen，open the refrigerator and suddenly you forget why you open it．“What am I looking for？”You ask yourself．“What am I doing here？”Don't worry．You are not losing your mind．We have all had this kind of thing．If you think about something very quickly，it goes into your short-term memory and it goes right back out in just a few seconds．You have not moved things from short-term to long-term memory，so you won't be able to remember it later on．
What can you do to help get back your missing short-term memory？You may go back to where you were．So，for example，if you were sitting in a chair listening to the music in the living room，just go back into the living room．This will help you remember，and when you are back in the living room，you will suddenly think，“Oh，yes，I was thirsty and I wanted something cold to drink．That is why I went to the fridge．”If，sometimes，you can't go back to where you were before，just try tracing your steps back in your mind．Think back to things you did before，and this may help you．
【小题1】We sometimes forget why we open the refrigerator, probably because___________.        

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.

In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙细胞﹚to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word ”means, we can help to save people from several illness. So the more we understand, the more doctors will be able to do.

Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的)，or stop sick people getting jobs.
