one part is rich  and the other is poor . In the poor part , a lot of people never get

starve (饿死)and in the other ,  a lot of people get fatter and fatter and have to

go on diets (吃特别饮食), or do special  exercises in order to lose weigt.     

　　The poorer countries have special problems . Sometimes the land is too

poor to grow  anything on . The land can be improved (改善), but a lot of

things must be done first . The  people must be educated an water must be

found.     

　　But rich countries have problems , too . There are not always pleasant

places to live in .  Sometimes the air is too dirty to breathe , and the rivers are

too dirty to swim in or to take  water from . The roads are too crowded to drive

along . Large numbers of people do not have  decent (象样的)housed to live

in . Some things will have to be done about these problems .  The air and the

river will have to be cleaned , and more houses will have to be built.
