Dear Mr ..... ,
I am writing this letter to complain about the factory near our village which has caused much air and water pollution. The factory is dumping a large amount of fumes into the air, which cause the respitory deseases of some villagers. Moreover, the factory also discharges harmful chemical waste into our village lake. It killed a lot of fish and now, no one can use the water from the lake because it is poisonous.
We all think the factory should be responded for their unconcious, dangerous and irresponsible action. We also believe the People's Committee should make the decision of punishing the factory heavily and prohibit them from contaminating the environment again in order to protect the villagers' lives.
We look forward to hearing from you and hope you will give the factory the right punishment.
Yours sincerely,
.........
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.

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.
