9. How should people protect
and preserve the natural resources?
Conservation concerns men’s safeguarding and preservation of natural resources and his responsibility for improving the environmental conditions in which he lives. An important task of conservation is the prevention of waste – waste of forests, soil, minerals, wildlife and human life.
Trees help to preserve land because their roots bind the soil and retain water. Without trees, heavy rains will cause soil erosion and the remaining land becomes poor and worthless. Terrible floods often occur in the areas where trees are cut down in great quantity. Forest conservation also means the prevention of bush fires and the attention to planting and looking after new, young trees.
Not only should man preserve forests but he should also realize the importance of wildlife protection. Unless governments have a good system of control or pass laws restricting the hunting, fishing and eradicating of rare animals and plants, they slowly disappear. Natural resources such as coal, gas and mineral ores are limited but the need for them is growing day by day. As they may not last for a century, man should use them widely on the one hand, and look for alternative fuels on the other hand.
Another serious problem threatening human life is the dirtying and poisoning of air and water. This pollution is mainly caused by the fumes, chemicals and wastes from automobiles, industries and homes.
It is hoped that for his own benefit, man can soon find a solution to these problems.

10. Life in the city, compared with life in the country
In my opinion, urban life or rural life has its own advantages and disadvantages. First, living in the city we may enjoy those benefits.
Communication and transportation systems are better. There are so many means of communication and transport that we can choose the ones we like best. We can get in touch with a friend or talk to him by phone without having to go out of home.
Thanks to electricity network and running water, our material lives are more comfortable. Supermarkets, markets and shops are found everywhere and we can buy anything we need providing that we can afford it.
- Urban life provides us with all sorts of entertainments: televisions, radios, movies, theatres, concerts and famous recreation centers.
Living in town we can improve our knowledge easily by attending any schools, universities or evening classes where experienced teachers and professors are ready to satisfy our thirst for knowledge.
Besides its advantages, urban life also has its disadvantages:
Our health is in danger: pollution by factories and heavy traffic may cause serious diseases to all of us.
Evil influence upon the young generation by obscene video films is inevitable.
Violent deaths happen regularly in such a crowded city with all kinds of vehicles. On the contrary, rural life seems ideal to all of us, especially to the old.
We can enjoy fresh, cool air and behold beautiful landscapes in the country.
How safe and delighted we are when we can sleep a sound sleep at any time of the day without being disturbed by sirens of cars or by deafening noises from manufacturing factories.
Our social lives in the country are easier: we can eat the food and vegetables we grow, the chickens and goats we raise. The countrymen lead a very simple life and they are quick at mutual help in any case.
Apart from these advantages, living in the country we may meet lots of difficulties too.
Communication and transportation are obstructed by lack of means of transport or by floods in the rainy season.
Our knowledge is limited by being short of mass media.
Our social and physical lives are not as comfortable as those in town because of lack of electricity and medical care.
In a nutshell, our love for town life or country life depends on our outlook and age. As for me, I always prefer rural life to urban life.

11. Should teachers give pupils too much homework? Discuss
Many people now think that teachers give pupils too much homework. They say that it is unnecessary for children to work at home in their free time. Moreover, they argue that most teachers do not properly plan the homework tasks they give to pupils.
The result is that pupils have to repeat tasks which they have already done at school.
Recently many parents complained about the difficult homework which teachers gave to their children. The parents said that most of the homework, and they wanted to stop it. Spain and Turkey are two countries which stopped homework recently. In Denmark, West Germany and several other countries in Europe, teachers cannot set homework at weekends. In Holland, teachers allow pupils to stay at school to do their homework. The children are free to help one another. Similar arrangements also exist in some British schools.
Most people agree that homework is unfair. A pupil who can do his homework in a quiet and comfortable room is in a much better position than a pupil who does his homework in a small, noisy room with
