VI- Read the following passage and then answer the questions:
More than two hundred years ago, the term environment pollution was quite strange to people. They lived healthily,
drank pure water and breathed fresh air. Nowadays, the situation is quite different. People all over the world are
worried about things that are happening to the environment. Actually it is man that is destroying the surroundings
with many kinds of wastes. Everybody knows that motorbikes and cars emit dangerous gases that cause poisonous
air and cancer, but no one wants to travel on foot or by bicycle. Manufactures know that wastes from factories make
water and soil polluted, but they do not want to spend a lot of their money on treating the waste safely. Scattering
garbage is bad for our health, but no one wants to spend time burying it. Is it worth talking a lot about pollution?
1. How did people live more than two hundred years ago?
2. What is the man doing with his environment?
3. What do the gases from motorbikes and cars cause?
4. Do the factories make water and soil polluted?
