Are you looking for a cheap, clean, effective source of power that doesn’t cause (1)_____________or waste natural resources? Look no further than solar energy (2)_____________the Sun. At present, most of our electricity comes from the use of coal, gas, oil or nuclear power. This power could be (3)__________by the Sun. One percent of the solar energy that reached the Earth is enough to provide power for the total population. Many countries (4)______________already using solar energy. Solar panels are placed on the roof of a house and the Sun’s energy is used to heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy, too. Sweden has an advanced solar energy program. There all buildings will be heated by solar energy and cars will use solar power instead (5)____________ gas by the year 2015.

46. The scientists are looking for a cheaper way to use solar energy to hear air and water.
47. Solar units are expensive.
48. Students learn to build their own solar collectors at universities and colleges.
49. Yes, I do. I think solar energy is expensive.
50. I think so because the solar panels are complicated and difficult to make. So, to make a lot, they’ll need to spend a lot of time, equipment, materials, and energy to produce these panels.
I. Fill each of the numbered blanks in the following passage with a suitable word.
About two hundred years ago, man lived in (1) greater harmony with his environment because/ since/ as (2) industry was not much developed. Today the situation is quite different (3). People all over the world are worried about what is happening to the environment (4), because of modern industry and the need for more and more energy.

People live in big cities and much of our waste, especially waste (12) from factories, electric power stations, the chemical industry and heavy industry is (13) very dangerous. Fish die in the lakes, rivers, and seas; forest trees die too. Much of this dangerous (14) waste goes into the air and is carried by the wind (15) for great distances.
Conservation is the safeguarding and preservation(1)........of.......natural resources, so that they can continue to e used and enjoyed.

As important is the fight against pollution of our(4)...environment......., in particular, the dirtying and poisoning of air and water.
