world's population. How to control the population growth is a big problem. Some people think it   2   to control
the population growth. But I don't quite agree   3   them, because where there is a will, there is a way.
      The question is how we could   4   it known to everyone how serious the population problem is. Our
farmland is becoming less and less to everyone. We have already got too many mouths to feed.   5   we control
the population growth, many people will die   6   hunger. Too fast population growth have been and will be bad
for our nation. Though laws have been passed to control the population growth, in some places   7   is done to
carry out (贯彻) the laws. We should make people   8   that it is foolish of them to bring too many children into
the world. They shall no longer do what they have been doing for many years.
      We are fighting   9   too fast population growth. Yet the fighting won't end   10   everyone knows its
important and does something for it.
