一、Reading
Have you noticed that it's getting warmer and warmer every year? To put it simply, that's because of air pollution. Scientists tell us that because of air pollution, the earth's heat cannot escape. This is known as global warming. If this situation is allowed to continue, it will just keep getting hotter and hotter. Then, can you imagine what will happen? We should all, therefore, do our part to stop polluting the air and help save the world.
