8.If you spend some time in an English-speaking country,you might hear the term"etiquette".It means normal and polite(61)social (社会的)behavior.
Etiquette is not the same in every(62)culture (文化),or in every situation.For example,standing very close to the person you are talking with is q(63)uite common in some A(64)sian countries.H(65)owever,if you do this in Europe,some people might feel uncomfortable.Even in China,we all know that etiquette is not the same in all
situations.P (66)erhaps we think that talking loudly in our own homes is fine,but there are other places where talking loudly is not (67)allowed (允许).For example,most people would (68)agree (同意)that talking loudly in a library,a m (69)useum,or a movie theater is impolite.Even if you are with your friends,it is better to keep your voice down in public places.In fact,we should also take care not to (70)cough (咳嗽)or sneeze loudly in public if possible.
