Unit 6 The Importance of Trees

Unit 6  The Importance of Trees

Part one - Vocabulary and Language Notes

Read the following passage carefully

Why do we need trees?
If you ask people why we need trees, most of them will answer: “we need wood from tees for building houses”; “we get fruit and nuts from trees”; “we make paper out of wood from trees”; “we can use wood as a fuel for cooking and heating”.  Recently, people have added a more serious reason to this list: “Trees help the earth to breathe” or “they protect us from global warming”.
It has been said that more than 5000 things in everyday use are made from trees.  Here are a few of them: furniture, sports equipment, pencils, magazines and newspapers, cardboard boxes, musical instruments and- believe it or not- some kinds of toothpaste.
In addition to these uses, trees also give us valuable chemicals. Turpentine, which is used as paint remover, is made from the sap of trees. Sap can also be used to make rubber.  If wood is heated, chemicals are produced which can be used to make medicines and some kinds of plastic.  Wood products can also be turned into paper, cardboard and materials from which clothes can be made.  You may be surprised to hear that wood products are also used in some types of ice cream and other foods.
So, the next time you are reading a newspaper, eating an ice cream, playing the piano or cleaning your teeth, just stop and think: how would you manage to do these things if there were no trees?
