Paragraph 1

Scientists  have  learned   a  lot  about  the kinds  of  people  need.  They  say  that  there  are several  kinds  of  food  that  people  should  eat  every  day， they  are：  （1）  green  and  yellow  vegetables  of  all  kinds；（2）  citrus   fruits  and  tomatoes ;  （3）  potatoes  and  other  fruits  and  vegetables;  （4）  meat  of  all  kinds， fish  and  eggs;  （5）  milk  and  foods  made  from  milk;（6）  bread  or  cereal  （谷類）， rice  is  also  in  this kind of  food;  （7）  butter，  or  something  like butter.

Paragraph  2

People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different  countries  eat  at different times  of  the  day.  In some  places  people  eat once  or  twice  a day; in  other  countries  people  eat  three  or  four  times  a  day.  Scientists  say  that  none  of  the  differences  is  really  important.  It doesnt  matter  whether  foods  are  eaten  raw  or  cooked，  canned  （罐装的） or frozen  （冷冻的）. It  doesnt  matter  if a person  eats  dinner  at  4  oclock  in  the  afternoon  or  at  11  oclock  at  night.  The  important  thing  is  what  you  eat  every day.

Paragraph 3

There  are  two  problems，  then，  in  feeding  the large  number  of  people  on  the  earth. The  first  is  to  find  some  way  to  feed  the  world s  population  so  that  no  one  is  hungry.  The second is to make  sure  that  people  everywhere  have  the  right  kinds  of  food  to  make them  grow  to  be  strong  and  healthy.
