Farmers in many parts of Africa can not got grow enough to eat and in some Asian countries there is too little rice. Wild animals are quickly disappearing because we have killed too many. However, it isn't enough simply to talk about the problem. We must act before it's too late to do anything about it. Join us now. Save the Earth. This is too important to ignore

Our sun is actually an orange, dwarf star. Although it is not nearly the ....hottest ....(hot) star known, its surface temperature is about 10,000'F and that of its interior is thought to be in the range of 20,000,000'F. We ......commonly ..... (common) think of the sun as burning, yet it's too hot to burn and is composed of elemental gases.
The sun is 865,000 miles in diameter and has a mass one-third of a million times ......greater ....(great) than the Earth's. Scientists believe that it's two billion years old and, instead of cooling, is still getting hotter. Perhaps, within the next two billion years, it will reach a temperature of sufficient intensity to destroy the Earth.
The sun's corona is almost as hot as interior. Solar prominences-tongues of hot gas-leap outward a half million miles from the sun's surface at speeds reaching 250,000 miles an hour. ........Fortunately... (fortune) , these prominences do not travel the full ninety three million miles to earth, nor are their terrific temperatures transmitted through space. Some of the energy from these ..disturbances ....... (urban) does not reach our atmosphere, however, and is believed to cause changes in weather.Our sun is actually an orange, dwarf star.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.
Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.

Fill in each numbered blank with a suitable word :
The continent of Antarctica is (1) such a huge place that if it (2) were a country, it'd be the tsecond biggest in the world, after Russia. It never gets warm there.It is (3) so cold in eastern Antarctica that even the summer temperature is lower (4) than your freezer at home. Although much of Antarctica consists (5) of ice, there is solid rock under it. The ice is so deep and heavy, howerver,(6) it has pushed the earth down. If all that ice melted, the land (7) would start to ríse as much as 500 metres. Scientists believe the ice is already melting, and if it continues, the world's seaa and oceans will rise by (8) up to 60 meters. They say we must take action now, so (9) as to advoid a globad disaster. We need to use less fuel like oil ang gas in (10) order to reduce the effect of global warming on Antarctica's ice.
