When you start talking about good and bad manners, you immediately start meeting difficulties. Many people just cannot agree with  36  they mean. We asked a lady, who replied that she thought you could tell a well-mannered person  37  the way they occupied the space around them. However,  38  second person thought that this was  39  a question of civilized behavior than good manners. Instead, this other person told us a story about an American who  40  (invite) to an Arab meal in one of the   41   (country) of the Middle East. The American hadn’t been told much about the kind of food he might expect.   42  he had known about Arab food, he might have behaved better. Immediately before him was a very flat piece of bread that looked, to him, very much like a napkin.  43  (pick) it up, he put it into his collar(衣领) so that it fell across his shirt. His Arab host, who had been watching, said nothing,  44  immediately copied the  45 (act) of his guest. And that, said the second person, was a fine example of good manners.

答案

36.what       37.by           38.a 39. more               40.had been invited

41. countries 42. If          43. Picking           44. but         45. action

阅读下面短文,回答文后问题。

据明人蒋一葵《长安客话》记述,昔日的永乐大钟,日供六僧击之,“昼夜撞击,声闻数十里,其声宏宏,时远时近,有异他钟”。如此美妙绝伦的钟声是怎么样形成的呢

从外表上可以明显看出,大钟的钟壁上下厚度不同,钟腰的厚度是94毫米,而钟口的壁厚是185毫米。测音表明,不同厚度的各个部分,都会产生相应的频率振动,发出不同的声音,而这众多分音的汇集就是一首雄伟的交响曲。

加上永乐大钟合理的合金成分比率,优雅钟声的出现就不是偶然了。明永乐大钟的成分中含铜 80.5%、锡16.4%及少量其他元素。当含锡在16%左右时,就能保证钟体强度、韧度适度,保持钟声振动的持续性;若含锡量过多或太少都会使钟声余音减短,那么就无法欣赏到永乐大钟闻声数十里的悠长钟声了。

同时还发现,永乐大钟的正下方,由一个直径4米、深0.7米的八角形地坑,它不单方便人们仰视大钟内壁,还有为钟声散音的功能,与现代舞台前乐池的声学作用异曲同工。

三管齐下方才造就了永乐大钟举世无双的完美音质。那么,明朝的能工巧匠是如何设计出这令人叫绝的声场呢

中国古钟千百年来的发展脉络有其自成一派的风格样式。中国钟的基本形状是钟声高度与口径之比在 1:0.7左右,西洋中则在1:1左右。中国钟用钟杵从外壁敲击,而西洋钟用钟舌从内部敲击,因而发出的声音比中国钟更加急促、高昂。

通过物理分析,钟声产生于撞钟引起的振动,而钟声的强弱、高低、音色主要取决于钟体的形状和材质。钟壁厚则钟声沉闷,反之清脆;钟体短而口径大则钟声消失得比较快,反之悠长。永乐大钟上端闭塞、下端钟口开放,形成钟顶小、钟腰细、钟身长、钟口外张似喇叭。当撞击时,引起钟声振动,使各分音的频率恰当,产生拍频现象。此外,成分分析的结果告示我们,永乐大钟的合金成分比率与《周礼·考工记》中的“六齐”大致相符。

根据本文,大钟下方地坑的声学作用是()。

A.方便撞钟材

B.方便观赏

C.汇聚分音

D.钟声散音
