( 贫民窟）（简陋木屋）

People must understand those who live in other cultures because we communicate with and do business with them regularly.

United States of America TV, movies, fast food, and fashion clothes are popular in many

countries in the world now.

Maybe English is becoming a global language because most English speaking countries have

strong developed economies in the world.

For most of the world’s people, life is poor, hard and seemingly hopeless.

Poverty, war and disease are three serious problems in the world today.

The world population is growing very quickly in poor countries and falling slightly

in rich ones.

All people have the right to liberty and safety, to education and freedom of thought and

speech.

In troubled areas the UN sends in peace keeping troops to stop the fighting.

People flock to cities, causing these areas to have high population

densities.

Slums develop in some areas because city governments don’t have enough money to

provide services for everyone so the poorest set up shacks to live in.
