When you start talking about good and bad manners you
immediately start meeting difficulties. Many people just cannot
agree what they mean. We asked a lady, who replied that she
thought you could tell a well-mannered person on the way they 71._______
occupied the space around them—for example, when such a
person walks down a street he or she is constantly unaware of 72._______
others. Such people never bump into other people.
However, a second person thought that this was more a
question of civilized behavior as good manners. Instead, this 73._______
other person told us a story, it he said was quite well known, 74._______
about an American who had been invited to an Arab meal at 75._______
one of the countries of the Middle East. The American hasn't 76._______
been told very much about the kind of food he might expect.If
he had known about American food, he might have behaved 77._______
better.
Immediately before him was a very flat piece of bread that
looked, to him, very much as a napkin (餐巾) Picking it 78._______
up, he put it into his collar, so that it falls across his shirt. 79._______
His Arab host, who had been watching, said of nothing, but 80._______
immediately copied the action of his guest.
And that, said this second person, was a fine example of
good manners.
71 on---by，本题考察介词的搭配。该句意为“根据人们如何占用周围空间的方式来判断。”本题易改错 well-mannered 为 good mannered，但 well-mannered 是正确的复合词，表示“有礼貌的”。
72 unaware---aware，根据上下文，此句意思应该是“在街上走时，他(或她)不断的碰到熟人。”
73 as---than，“more……than……”是一个固定搭配，意为“与其说是(后者)，不如说是(前者)”。
74 it---which， 本题考点：句子结构，代词及定语从句。逗号后，人称代词he 前的代词it 显然不可能出现在正常的英语语句中，根据对本句主从句的结构分析，可确定两逗号间为 非限制性定语从句。
75 at---in，“在某个国家”应该用“in the country”。
76 hasn’t---hadn’t， 谓语的时态是否一致是六级改错常考的问题。
77 American---Arab，根据上下文，本句意为“如果这个美国人对阿拉伯饮食有所了解，他就会在就餐时表现得更好些。”
78 as---like，本句意为“他面前摆着的那些及薄的面包片，看起来很象餐巾。”as 的意思是“作为(事实上是)”;而此处是意思是“看起来像(事实上不是)”，所以应该用like。
79 falls---fell， 保持与上文的时态一致。
80 去掉 of , say 是及物动词，后面应直接跟宾语。
