As is known to us,China has the biggest population in the

world,which is more than 1,300,000,000.Such a large population causes

some problems in cities,that's the unemployment.Too many people gather

in cities and the jobs are not enough.Some graduates can't find a job

though they have left school for years.In addition,traffic jam is

another problem resulting from the big population.There are too many

cars on the roads and streets.　　The situation of the countryside is not

good.Too many people live in the countryside and we don't have enough

farm land for them.　　Fortunately,our government has realized the

problems and has attached great importance to them.
