阅读下面短文，根据所给语境，按要求完成下列各题。

    The first walk into outer space was taken by a Soviet astronaut. Astronaut Zhai Zhigang became the first
Chinese to walk in space on September 27,2008. It showed that it was quite safe for a man to be outside the
spaceship for a certain period of time. But to walk in space, astronauts have to meet with many kinds of
difficulties and dangers.
    The spaceship goes round the earth at an altitude (海拔高度) of about 200 kilometers above its surface. At
such altitudes there is no atmosphere which prtects the life on the earth. The conditions of outer space are very
harmful to man.
    The boiling point of liquids (液体) goes down with pressure. But pressure outside the spaceship is nearly
zero. In such conditions the decompression (减压) of the spacesuit may cause the boiling of the blood and quick
death. There is radiation from space and it is harmful.
    Breathing problems in space can be solved with the help of the spacesuit. Another problem is heat. Man gives
off heat in the course (过程) of his activity, and the harder the labor (劳动) is, the greater the amount (总量) of
heat is. In space unless special measures are taken, the heat inside the spacesuit would make the conditions
difficult.
