Someone is singing next door, but you feel unhappy because her singing is terrible. So you think she is just making noise. We know that too much noise makes people feel terrible.
Scientists are still trying to find out more about noise, but already it is known that a noise of over 85 decibels(分貝) can make some people tried and anxious(焦慮的).
In the past we thought only workers in very noisy places became deaf easily. Today, scientists believe that 10% of all workers in Britain become deaf in their work.
There are also new dangers from noise. Pop music, for example, can reach 120 decibels when it is played loudly five feet away! Only a plane can make such loud noise when it takes off.
There was an experiment in the United States. Some people would be given a lot of money if they stood below a jet when it was taking off over their heads. No one got the money after the jet flew past because all of them died in the noise.
People can’t pay their attention on what they are doing when there is much noise. Workers in noisy offices, for example, do their work more slowly than workers in quiet offices. Another study shows that workers in factories can do dull(枯燥的) jobs better when lively music is played for them. 

Have you heard of the term “etiquette” And do you know that etiquette is not only a useful word 46 very useful to understand?

Etiquette is not the same in every culture 47 in every situation. For example, standing very close to the person you are talking with is quite common in some Asian countries. However; if you do this in Europe, some 48 people might feel 49.Even in China, we all know that etiquette is not the same in all situations. Perhaps we think that talking loudly in our own homes is fine, but there are other places where talking loudly is 50 .For example ,most people would agree that talking loudly in a library, a museum, or a movie theater is 51 .Even if you are with your friends, it is better to keep your voice 52 in public places. In fact, we should also 53 not to cough or sneeze loudly in public.

If we see someone 54 the rules of etiquette, we may politely give them some suggestions. Perhaps one of the most polite ways 55 ask someone, Would you mind doing this or Would you mindnot doing that. For example, if someone cuts 56 you in a line, you could ask them, Sorry, would you mind 57 the line? If someone is smoking on the bus you could ask, Excuse me, could you please 58 that cigarette? People don’t usually like 59 , so we have to be careful how we do this.

Although rules of etiquette can often be different, some rules are the same almost everywhere in the world! For example, 60 is almost never allowed. If you see someone you know doing this, you can ask them, Would you mind picking it up?
