Do you think there is too much noise in our city? If you live near an airport,you will be unhappy because of a plane often make a loud noise.The sound of planes or heavy vehicles is likely to cause deafness if heard continuously(不断地).

However, most people in our city do not seem to mind noise. They like to enjoy music when they are doing uninteresting jobs.It is a new danger because pop music,when played through powerful amplifiers(放大器),can reach 120 decibels(120分贝的)at a distance of five feet.A continuous noise of over 85 decibels can cause deafness.It was discovered that many young people in America could hear no better than 65-year-old people.

In the past we used to think that only workers in very noisy places would become deaf.For example,when newspapers and books are being printed,the noise level is over 85 decibels,and some of the workers become deaf.Today,however,scientists believe that 10 percent of the workers in Britain are being deafened by the noise.

Sometimes noise of less than 85 decibels can make some people tired and stressed.We all know that too much noise makes life difficult and unpleasant.It can do great harm to people's health and prevent people from working well.Workers in noisy offices are not as efficient(效率高的)as those in quiet offices.Noise makes people less efficient.Can anything be done to reduce or control noise?

In Britain the government has made several laws to reduce noise.Though the government has spent a lot of money in making airports and main roads quieter,many people think that there are still not enough laws.For example,there are no laws to control the noise of machines.In Japan,America and Norway there are such laws.As a result,workers can be given compensation(赔偿)if they become deaf.

The Earth is getting warmer because of the activities of people. We cut down and burn 61 and send gases into the air with our cars and factories. Can we do anything about it? Sure. We may not be leaders or scientists but we can play our part in 62 the planet. Here are two ideas.

Bike, don’t ride to school

Do you go to school by bus or by bike? If you bike, you are doing 63 for the Earth. Buses, cars, trains and planes produce a lot of carbon dioxide(二氧化碳). If you live near to your school, 64 not bike there on warm spring mornings? Or, you can simply walk to school to save energy.

Wash the green way

Do you help your mom and dad wash clothes? Then wash them in an energy-saving way. A recent study by Cambridge University found 65 60 percent of the energy used on a piece of clothing is 66 in washing and drying it. Over its lifetime, a T-shirt can send up to 4 kilograms of carbon dioxide into the air.

67 you wash your own clothes, wash them in cold or warm water to save energy, but not hot water. Wash your clothes when 68 fill up the machine. Use the most energy-saving machine you can find. Some new ones use as 69 as one-fourth of the energy of older machines. When they’re clean, dry 70clothes the natural way, by hanging them on a line rather than putting them in a dryer. In all, you can cut the carbon dioxide used in washing by 90 percent.
