                                           Step 2
      Ex. 6. Read the text.

       Biology is the science of life. It studies life in all its diversity. Biology tells us
about our body: how it is constructed and how it functions. It gives us information about
other living things, and how their lives affect mankind. A knowledge of biology will
help you to keep healthy. It will be your guide in solving many of everyday living and
scientific problems.
       Biologists have made a great contribution to science. They have increased our
food supply. They have developed new and better varieties of plants and animals.
Scientific methods of farming have given us much more food.
       Biologists control many diseases. They have saved millions of lives by
discovering the causes of these diseases and methods of their prevention and cure.
Vaccines, penicillin and sulpha are products of the biological laboratory. Biologists
have solved many mysteries of the body. They have discovered how blood circulates,
how food is digested and many other secrets of life. They are now working in different
fields of biology and their studies may lead to a solution of many problems.
