Stone is all around us. Stone is usually very hard, it can also be soft. Stones have many uses.

In some , artists carve (雕刻) beautiful things out of soft stones, because they can be shaped easily. In ancient times, people carved persons or animals out of soft stones, which could be carried along with. While in some European countries, statues (雕塑) are carved hard stones and they do not change easily. In summer, the hot sun on these statues and in winter the snow falls on them, but they remain beautiful.

Stone is strong and long-lasting. So, it is enough for buildings. A house built of stone does not catch fire as easily as made of wood. Some stones are coloured, so they make the look wonderful. People can also get a fire with stones. Besides, some kinds of stones can be used to jewellery (珠宝). We’ve found stones are really amazing.

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.
