DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own. People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named genes in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language. In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now 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 save more people from several illnesses. Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn‘t limited in use. 根据短文内容，选择最佳答案。 (     )1. When did we first know why we look like other people in our family? A. In 1860. B. In 1953. C.

Some people suffered from a fever or a cough.   Don’t be afraid--it’s not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes.   Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses.   Cover your nose and mouth.

And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands.   Wear a mask. Some doctors say that masks can stop the flu as much as 80%, but if you don’t wash your hands often, it’s no use wearing a mask.
