Plans grow(46)in almost every part of the world. We see(47)such plants as flowers, glass, and tree nearly every day. Plants grow high on moutaintops, far in the oceans, and in many deserts and(48)polar regions
Without plants, there could be not life on earth. Man could not live without air of food and so he could not live without plants. The oxygen in the air we breathe comes from plants. The food we eat also comes from plants or from animals that eat plants. We build houses and make many(49)useful products from lumber cut from trees. (50) Much of our clothing is made from the fitbers of the cotton plants.
Scientists belive there are more than 350,000 species of plants, but no one knowns for(51)sure. Some of the smallest plants, called diatoms, can be seen only with a(52)microscope . A drop of the water may hould as many as 500 diatoms. The largest living things are the giant sequoia trees of California. Some of them stand more than 290 feet high and measure over 30 feet wide
Scientist(53)divide all living things into two main groups - plants and animals. It is usually easy to tell the two(54)apart . Almost all kinds of plants stay in one place, but nearly all species of animals move about under their own power. Most plants make their own food from air, sunglight, and water. Animals cannot make their own food. The basic units of all life, called cells, are also different in plants and animals. Most plants have thick wall that(55) contain a material called cellulost. Animal cells dl not have this material.

There are many kinds of pollution. Air, water, and land can be polluted. Some pollution is caused by nature, such as floods, forest fires, and volcanoes. People are the major cause of pollution. We pollute the air with our cars, homes, and factories. Smoke from factories and car exhaust makes the air looks gray and smoggy. Some people cannot go outside when the air is very bad! We pollute the water by dumping garbage and chemicals in the water. Plants and animals die because of the pollution in the water. We pollute the soil with chemicals and garbage. We harm the land by cutting down trees in the forest, especially to build roads and new houses without careful planning and thinking.
The only way to save our environment is to think about pollution. How can you stop or limit pollution? How do we protect our environment? Conservation is one way to protect our environment. Conservation is the wise use and protection of our environment. We can control water pollution by not producing as much waste and by proper disposal of sewage and garbage. We can take care of recreation land by cleaning up after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air pollution.
Recycling is a type of conservation. Recycling is reusing items over again or in a new way. Recycling can help US conserve our natural resources so they will last many more years.
A. Find the word in bold in the passage that means:
1. the protection of the natural environment Conversation
2. have a bad effect on something dumping
3. a large amount of water covering an area that is usually dry floods
4. sharing a car ride with other people carpooling
5. waste gases that come out of an engine exhaust

7. get rid of exhaust
Fill in the blanks:
Maybe you recycle cans, glass and paper. Do you know that nature recycles, too? One of the things nature (1)...recycles... is water.Water goes from oceans, lakes and river into the air. Water falls from the air as (2)...rain... or snow. Rain and snow eventually find their way back to the ocean. Nature's recycling program for water is (3)...called... the water cycle.
The water cycle has 4 stages: storage, evaporation, precipitation and runoff. Water on the Earth gets stored (4)...in... oceans, lakes, rivers, ice and even underground. Water goes from storage into the atmosphere by a process called evaporation. When water evaporates, it changes from a liquid (5)...into... a gas, called water vapor. Water vapor goes up into (6)...the... atmosphere. Water returns to the Earth as precipitation in rain or snow by changing into drops of water (7)...when... the air gets cold enough. Clouds are collections (8)...of... water droplets. Most precipitation falls into the oceans and go right back into storage.
Water that falls on land always flows from (9)...higher... places to lower ones. This flow is called runoff. Water from land flows into streams. Streams join together to make (10)...rivers... and eventually the water flows into storage in the oceans.

Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.
