EXAMEN CF GRADO SUPERIOR

READ THE TEXT AND DO THE TEN TASKS BELOW In English we sometimes say, "It's raining cats and dogs" when it's raining very hard. Cats and dogs don't usually fall out of the sky but .... • In 1859 In Aberdare, Wales, small fish fell with the rain‑twice in the same morning. • In 1922 In Hungary spiders came down with the rain. • Red rain fell in Switzerland in 1755 and 1903. Things like these don't happen often and they're. not really a big problem when they do. Other things in the rain, however, are a problem. Scientists and people living in industrial countries (or near industrial countries) are very worried about "acid rain". Our cars, our power stations and so on send chemicals like sulphur dioxide (SO2) and nitrogen oxides into the air. These chemicals mix with water and become sulphuric acid (H2S04,), nitric acid (HN03), and other things. They fall as acid rain. Acid rain kills fish, insects, animals, birds, trees and ‑eventually‑ us. Acid rain is becoming a very big problem in Europe. One day, if we don't do something, it will be a big problem ‑a terrible problem‑ for every country in the world. QUESTIONS 1. GIVE A TITLE TO THE TEXT 2.
