Space is a dangerous place,not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through,and this is essential for plants to make the food which we eat. Heat,too,makes our environment endurable. Various kinds of rays come through the air from outer space,but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation. But their spacesuits or the walls of their spacecraft,if they are inside,do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space. The unit of radiation is called
"rem". Scientists have reason to think that a man can put up with far more radiation than 0. 1 rem
without being damaged;the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well,but the cells of his or her sex organs may be damaged,and this will not be discovered until the birth of deformed(畸形的)children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and,during the outward and return joumeys,the Apollo crew accumulated a large amount of rems. So far,no dangerous amounts of radiation have been reported,but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere,working in a space laboratory. Drugs might help to decrease the damage done by radiation,but no really effective ones have been found so far.

It seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain.lts first use was as a shade against the sun !
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, as early as the eleventh century B. C.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honour and authority. In the Far East in ancient times the umbrella was allowed to be used only by royalty or by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is beheved that the first persons in Europe to use the
umbrella as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared
again in Italy in the late sixteenth century. And again it was considered a symbol of power and
authority. By 1680, the umbrella appeared in France, and later on in England.
By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight.lt wasn't until the twentieth century that women' s umbrellas began to be made, in a whole variety of colours.
