8.2.7.1 8.4.7.1 TREE PARTS and functions * Read the texts and comple correct missing words. Compare with your partner. VIDEO Listen and check. Trees are an essential part of our world. They provide homes for insects and birds, wood for building and the ingredients for making paper. But most importantly, they keep our air clean by turning carbon dioxide into the oxygen that we need breathe. Every part of a tree plays a specific role: 1). ROOTS Trees are the strongest plants in the world. It takes a lot of support to stop such a big structure falling over. The trees' roots spread deep underground and keep the tree standing upright. They are covered 2) very small hairs that suck up water and minerals from the ground. The main roots then take the water to the rest 3).. the tree where it is used in photosynthesis. LEAVES The leaves are the most important part of the tree as they make the plant's food from water, air 6) sunlight. They are full of a special substance called chlorophyll that absorbs sunlight and allows the tree to turn water and carbon dioxide 7) glucose which the tree uses as food. Chlorophyll is what gives leaves their distinctive green colour. CROWN The crown is the top part of a tree. It is made 4) of leaves and branches and performs several roles. It shades the roots from the sun and stops them from drying out. It also gathers energy from the sun and releases extra water 5) the environment to cool down the tree. the BRANCHES Branches are connected 8) trunk and have a lot of shapes and sizes. Leaves, flowers, or fruit can grow on them. They can store glucose from the leaves and serve as a 'pipe' for water and nutrients. A small branch is called a twig. TRUNK The trunk is the central part of the tree which takes water and minerals from the roots to the branches, twigs and, finally, the leaves.

Books... I think that we can't live without them. I believe that books stay with us for all our life. When I was a child my parents read them to me. I was happy to listen to the stories and tales. I learned a lot of interesting things from books. I remember thtat I liked thick books. Later I've learnt to read myself. I like to read books about animals, nature and children. I like to get presents on my birthday. I am happy if it is a book. It doesn't matter what kind of book it is. I like to read almost all books. If I have spare time, I spend it with my favourite book. When I was fifteen I was fond of reading too. But I preferred to read books about travels. I travelled with the heroes of the stories. I saw many interesting places and learned a lot of important facts about other countries and people. Now I like to read books about science. You can learn a lot from books. I am sure that books play a very important role in my life. Books must be our friends during all our life.

От! Але это не точно:

1. The word "environment" means what is around us. People who live in large industrial centers, cities and towns live in urban environments. For others, the environment is rural. Everyone who lives in

cities or small villages breathe air, drink water, use soil that needs to be clean. But are they really clean?

2. Water in oceans, seas and rivers is polluted in many places. If people drink this water, they may get sick or even die. People use the oceans and seas as large landfills and pour in them industrial and household waste. And so the fish becomes toxic. It’s very dangerous for people to eat such fish. Water birds leave places with toxic water. Many trees on the coast also die.

3. What we eat is not always healthy food, since fruits and vegetables can grow on contaminated soil and become dangerous. The meat that we get from sheep and cows can be bad for our health if these sheep and cows eat grass that grows on polluted lands.

4. People cut down trees, and many birds and animals cannot have houses in their usual places, and they begin to die. If the situation does not change, soon we will live in a completely different world - a world without a number of species that we know now.

5. At present, people feel that it is harder to breathe: in large cities, the air is very polluted. Most of the pollution comes from cars and buses. Old people and young children feel bad and are sick due to polluted air.
