I moved to this small town at the age of twelve.After getting  36   in our new house and starting school,I began to explore the   37  area.I was exploring the pond when I discovered the fish.

There were two of them,one about a foot long,  38  the other just a little smaller,and they were the most beautiful fish I had  39  seen.They had blue and yellow and red  40  from head to tail.Before they saw me,they swam  41  over the sand just under the front edge of the large cedar(杉)tree which had long before fallen  42   the pond.

I went back the next day after school  43   with about six feet of fishing line and a hook borrowed from our elderly neighbor.and half a dozen worms I had   44  out of the garden.We did not own any fishing tool,and   45  a city kid,my fishing experience, had  46  week long visits to my relatives.

I took a shortcut  47  some fallen cedars on my way to the pond.As I was climbing over one tree and ducking under another,I  _48  my footing,and my soup can of worms went flying into the air.My  49   was only increased when I noticed that my worms had disappeared.

I went to the pond,looked down again,and there they were.I made a few  50   to catch them by hand,but I soon realized it was never going to  51 .I had been trying to catch them for quite a while without actually even  52   either one.After each attempt,they   53  suddenly go around the pool,then settle back under the log.They could really go  54 ,but they were just too fast to be caught.I was wet and   55   and it was time to go home.

(二)阅读《编钟里的科技与奥秘》,回答14—17题。(共8分)

①在古代,世界各地都有钟,但它们都没有成为乐器,这是因为这些钟的截面是正圆形的,声音持续时间太长。唯独中国的编钟,它的截面像两片瓦合在一起,因为钟体扁圆,边角有棱,声音的衰减较快,所以能编列成组,作为旋律乐器使用。

②在湖北省随州市出土的曾侯乙墓编钟共有65件,是迄今发现的最大最完整的一套编钟。曾侯乙墓编钟铸造于两千五百年前的战国时代,它气势恢弘,总重量达到两千五百多公斤,加上横梁、立柱等构件,用铜量达五吨之多,这在世界乐器史上是绝无仅有的。更神奇的是,每一个编钟都能发出两个乐音,这两个音恰好是三度关系。

③曾侯乙墓编钟的音域宽达五个半八度,而且十二个半音齐备,是世界上已知的最早具有十二个半音的乐器。

④编钟的发声原理大体是,编钟的钟体小,音调就高,音量也小;钟体大,音调就低,音量也大,所以铸造时的尺寸和形状,对编钟有重要的影响。

⑤即使在今天,铸钟仍不是一件易事。有的编钟形体很大,高度超过一米五,制造时需要用136块陶制的模子组合成一个铸模,灌注摄氏近1000度的铜水才能得到。从出土的编钟来看,它们不仅音调准确,而且纹饰极为精细,这说明商周时期青铜模具的制造技术运用得极为熟练。

⑥编钟在铸造时,除了考虑钟的美观,还要注意它的声学特点。编钟表面被称为“枚”的突出部分,不仅仅是一种装饰,它还能加快声音的衰减。

⑦青铜是一种合金,主要成分是铜,又加进了少量的锡和铅,各种金属成分的微妙的比例变化,对钟的声学性能、机械性能有重大的影响。青铜中锡含量的增加,能提高青铜的硬度。但含量过多,青铜就会变脆,不耐敲击。铜中加铅,可降低熔点,增加青铜熔铸时的流动性,还可以减弱因加锡导致的脆性,使所铸的钟耐击经用。但是含铅量过高,钟的音色又会干涩无韵。而曾侯乙编钟里,铜、锡、铅的含量达到了最合理的比例,可见春秋战国时期,人们已经对合金成分与乐钟性能的关系有了精确的认识,正因为如此,铸出的钟才音色优美,经久耐用。
