In the morning, Mr. Martin comes i   1  his garden. He sees too m  2  snow(雪) in the garden. Mr Martin wants to t  3 his car out, s  4  he asks a cleaner(清洁工) to clean the road from his garage(车库) to the gate. He s  5  to the cleaner, “Don’t put any snow on the f  6  or on the wall. And don’t put any into the street, or(否则) the p   7  will come.” T   8  he goes out. When(当) he comes back, the road is clean. There is no snow on the flowers, on the wall or in the street. But when he o   9   the garage to get his car out, he sees it is full of snow, the snow from the road, and his car is u  10  the snow!

On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could read the whole “map” of the human body: DNA. 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 Matthaci 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（限制）in use.
