PASSAGE 2: Read the following passage about protecting the environment and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions
Most people today know about global warming. They know our planet is in trouble. The weather is changing, the seas are rising and the ice caps are melting. Why is it then that nobody seems to be doing anything about it? Perhaps they don't know what to do?
[I] There are lots of things we can do that will help. [II] Firstly, we must stop using aerosols, such as hairspray and spray deodorants. [III] The ozone layer is very important, as it filters the light from the sun. [IV] If we didn't have the ozone layer, the sun's light would be too dangerous for us.
In addition, we must use public transport instead of cars. Cars produce carbon monoxide. This is a very dangerous gas which pollutes the air. We must also stop pouring chemicals and waste into rivers and lakes, as this pollutes the water and kills the plants, fish and birds which live there.
Furthermore, we must stop cutting down trees and destroying the rainforests. We need trees because they produce oxygen which we all need to breathe. Also, if we cut down trees, we destroy the homes of animals and birds.
However, it will take more than just this to make any real changes. Governments can help, too. They have to make car manufacturers, factories and oil companies promise to take positive action. They cause most of the pollution and do little to control it. We can help by writing to politicians and company directors asking them to reduce this. We can use our votes to elect people who promise to improve the situation and change things for the better.
