1. Talk about the city and in the city
In my opinion, the countryside is a beautiful place. I love it because it is qiuet and life here is very slow and easy. We never have to queue in shops and we can drive bikes on street comfortable because there’s much heavy traffic .In the countryside,people plant vegetables and raise cattle themselves.So the food is very fresh here. In addition, the air is clean.It makes us have a good healthy.
The people are friendly.Everyone know everyone and if someone has a problem,there are always people who can help.
But the countryside is too quiet.There’s no things to do.
It’s don’t have any parks or movie theaters. And many people feel bored.
The city life is the opposite.There are any places for entertainment.People can relax by going to the zoo, playing games… And children in the city have chance to learn more because the education is good.There are many kind of food here and they are delicious.But people are unfriendly and the city is noisy and plutted air.
Each place has some benefits anh limitations.
I live in the country. I like the life here. But I always want to live in the city because it is good for my future.

Newspapers and magazines write (5) about water pollution, air pollution, and land pollution.
Why is there so much discussion about pollution (6)? After all, people have been polluting the world around (7) them for thousands and thousands of years.

Now, however, many parts of the world are crowded (11). 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.
