In the past, man did not have to think about the protection of his environment. There were few people on the earth, and natural 36 seemed to be unlimited.
Today things are 37 . The world has become too 38 . We are 39 our natural resources too quickly, and at the same time we are 40 our environment with dangerous chemicals. If we 41 to do this, human life on earth will not 42 .
People realize today that if too many 43 are taken from the sea, there will soon be none left. Yet, with modern fishing 44 , more and more fish are caught.
We know that if too many trees are cut down, 45 will disappear and nothing will 46 on the land. Yet, we continue to use bigger and more powerful machines to 47 more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. 48 , in most countries waste products are still put into rivers or into the sea, and there are few laws to 49 this.
We also know that if the 50 of the world continues to rise at the present rate, in a few years, there won't be enough food. What can we do to solve the 51 ? If we eat more vegetables and less 52 , there will be more food available for everyone. Land that is used to grow crops feeds five times more people than land where animals are kept.
Our natural resources will 53 longer if we learn to recycle them. The world population will not 54 so quickly if people use modern methods of birth control.
Finally, if we 55 people to think about the problems we shall have a better and cleaner planet in the future.

Most people believe they don’t have much imagination. They are 11 . Everyone has imagination, but most of us, once we become adults, forget how to 12 it. Creativity isn’t always 13 with great works of art or ideas. People at work and in their free time 14 think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
Making connections. This technique involves taking 15 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words 16 with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 17 to the job you have to do. So imagine you want to buy a friend an original 18 ; you could buy him tickets to match or take him out for the night.
NO limits! Imagine that normal limitations don’t 19 . You have as much time /space / money, etc. as you want. Think about your goal and the new 20 . If your goal is to learn to ski, 21 , you can now practise skiing every day of your life (because you have the time and the money). Now 22 this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a 23 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the 24 in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their 25 . The best fishermen think like fish!

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It's all very good to ban human cloning but scientists should be allowed to 47
research. If they don't, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.

How to get rid of waste is a great problem for the world today. Waste must be treated 16 it does not become a danger to life. 17 , in some countries, waste from factories is still poured straight into rivers. People who use the water from one of these rivers often get 18 . The water may become so polluted that it 19 all the fish in the river. When these rivers finally reaches the 20 , it pollutes the ocean.
In many countries with 21 , human waste is piped directly into the sea without being dealt with. This is not 22 . Although the sea itself can break up the waste, beaches 23 become polluted. 24 scientists suggest people take the waste far out to sea in ships where the wind and waves break it down.
In 1989 an international law was passed to 25 people putting waste into the sea. It is now against the 26 to put anything into the sea nearby. Such rubbish as plastics may not be thrown 27 the sea anywhere. Other waste may be put into the sea, either 19 or more than 40 kilometers from land, 28 the nature of the materials.
The 29 of dealing with waste has become so great that several international organizations have been 30 to protect the world and control pollution.
