Norwich is the capital of East Anglia, an area on the east coast of England which is famous for its natural beauty and impressive architecture. Norwich is a wonderful city to explore and is popular with tourists all year round. Norwich is not a city of luxurious hotels, but it has a good selection of reasonably priced places to stay in, both in the city centre and further out. The Beeches Hotel, for example, next to the cathedral, has a beautiful Victorian garden. Comfortable accommodations costs \u00a365 for two nights' bed and breakfast per person. Norwich is famous for its magnificent cathedral. The cathedral has a summer programme of music and events which is open to the general public. One event, \\\"Fire from heaven\\\", is a drama and musical performance with fireworks, a laser light show and a carnival with local people dressed in colourful costumes. Norwich is also home to the Sainsbury Centre for Visual Arts, a world-class collection of international art in a building at the University of East Anglia. This is well worth a visit and there is a lovely canteen with an excellent selection of hot and cold snacks. It also specializes in vegetarian food. In addition, the city has a new professional theatre, the Playhouse, on the River Wensum. The city's annual international arts festival is from 10 to 20 October. Finally, if you fancy a complete break from the stresses of everyday life, you could hire a boat and spend a few days cr uising along the river of the famous Norfolk Broads National Park. In our environmentally friendly age, the emphasis has moved forwards the quiet enjoyment of nature and wildlife. You can buy hire a boat, big or small, for an hour or two or even up to a week or two. This makes a perfect day out or holiday for people of all ages.

The population of the world is growing very fast. In the last 40 years, it has doubled. By the year 2200, it will be about 10,000 million. Our cities will be much bigger. There will be more factories and more roads. We will need more water and more natural resources. Experts say that we will have serious problems in the future. They say that we must change the way we use energy and natural resources now. Every day we throw away millions of tons of rubbish. Half of this is paper that we can use again. A typical family in Europe or America throws away more than l ton of rubbish each year, but we can recycle most of this. If we recycle things, we can save money, energy, and natural resources. Recycling the Sunday New York Times newspaper, for example, will save 75,000 trees every week. A lot of rubbish we throw away is not biodegradable. Plastic, metal and chemicals will not disappear for hundreds of years. We also produce a lot of unnecessary things, such as packaging. All of this pollutes the air, the land and the water. Pollution will be a very big problem in the future. We must avoid using non- biodegradable material. We must also reduce the number of unnecessary things that we produce and use. In shops, for example, we can say \u201eNo, thanks!\u201f to the packaging that comes with the things we buy. Many natural resources are not renewable. Coal, gas, oil, metals and minerals, for example, will finish one day. Other resources take a long time to grow, such as trees, or they are not always available, such as water. We have to reduce the number of resources and energy that we use. We also have to find alter native ways to make energy. We can use the sun, the wind, the sea and the heat of the Earth. Choose an option (A, B, C or D) that best answers each question. 36. The certain consequence of a fast growing population is that . A. the number of people on earth is going to double B. there will be more natural resources C. the change in the way people use energy D. the lack of water and resources 37. Which of the following is NOT true about recycling? A. We can save money. B. A major part of rubbish is recyclable. C. Every day millions tones of rubbish are reused. D. 75,000 trees will be saved if we recycle one daily newspaper. 38. The word \u201ethis\u201f in the passagerefers to . A. packaging B. rubbish C. the non-biodegradable D. plastic 39.
