阅读下面短文,按要求完成31~35题。
Do you know about DNA Here is an introduction of DNA.
DNA is short for deoxyribonucleic acid. It contains genetic instructions. These instructions are used in the development and functioning of all known living organisms(有机体). That’s to say your DNA decides what you are like.
Perhaps this is a little bit difficult for you to understand. Here is an example to explain it more clearly. Before you were born, your DNA had already decided you would have two hands and that each hand would have five fingers. Your hands would help you hold things and do many other things.
However, DNA is more than that. We get our DNA from our father and mother. That is why we look like our parents and are not like others. Also because of different DNA, Chinese
people look different from Americans. Chinese people have black hair and eyes, but many Americans have blue eyes and blond hair. Though we have discussed many things about DNA here, there is still a lot more to know about it. If you would like to know more about DNA, you can go on the Internet.
