“解元”漫谈

高玉林

①当谈起中国的科举制度，不少人会把“解jiè元”错读成“解xiè元”。

②元：第一。解元：封建时代称地方（明、清指省一级）科举考试第一名。唐、宋科举制度规定，参加全国性科举考试（礼部试）的人必须经地方考试选送，这种地方考试称“解试”，解试第一名就稚解元，由所在州郡发遣解（jiè）送至京参加礼部会试，称“发解”。这里，“解”取“发遣解送”之义，当然要读成ji了。明代的唐寅就是因为考中乡试第一名，而被人称作“唐解元”。

③宋元以后，解元逐渐演变为对读书人的尊称或通称。如元·王实甫《西厢记·惊艳》：“（张珙唱词）分明打个照面，疯魔了张解元。”再如“董解元”。董是金代戏曲作家，生卒年月、字号、籍贯均不详，因其为读书人，故人称董解元。他根据唐代元稹的《莺莺传》创作了长篇讲唱文学《西厢记诸官调》，为元杂剧《西厢记》所本，世称《董西厢》。

④《幼学琼林》中提到了“解元”：“中状元，曰独占鳘头；中解元，曰名魁虎榜。”与此相关的，说说“五魁首”。明代科举分五经试士，每经所取第一名谓之经魁。乡试中每科前五名必须分别是某一经的经魁，故称五经魁。其后五经试士制虽废，但习惯上仍称乡试所取前五名为五经魁。也叫“五经魁首”，亦省称“五魁”。现在人们饮酒划拳时喊的“五魁首”就源于此。

⑤历史上，我国江苏无锡曾有过“一榜九进士，六科三解元”的盛事。所谓“六科三

解元”，是指明代隆庆四年和万历元年、四年、七年、十年、十三年中，无锡吴汝伦、顾完

成、周继昌在乡试中连获第一名，彰显出无锡文风之盛。

⑥京剧中有一出《苏三起解》，非常有名。这里的“起解”指犯人被押送上路，“解”同样读jiè。

⑦我在报纸上看过这样一篇文章，或许能够帮助我们记住“解元”的读音。

⑧相传明代解缙参加乡试考了第一名，称解元，闻名远近。一次他游山口渴，向一位老者讨茶喝。老者问他身份，解缙直报自已是“解解元”。老者想挫挫解缙的锐气，说他出一个对子，解缙对得上方能喝茶，因以出句：一碗清茶，解解解元之渴。此句古今称绝，难在联中三个“解”字。三个“解”字字同义异，三字三用，应对颇难。后来解缙知道老者姓乐，曾在朝廷乐府为官，后隐居山林，抚琴乐山乐水，便灵机一动对出下联：七弦妙曲，乐乐乐府之音。对句三“乐”对三“解”，词性、功用分别对应，对仗工整，即景应对，切人切事切情。

⑨在上文中，三个“解”字与三个“乐”字的正确读音为：解（jiè）解（xiè）解（jiè）元之渴。第一个“解”是“消除”的意思；第二个“解”是姓氏；第三个“解”与“元”台起来表示乡试第一名——“解元”。

⑩乐（lè）乐（yuè）乐（yuè）府之音。第一个“乐”是“快乐”的意思；第二个“乐”是姓氏；第三个“乐”与“府”合起来表示汉代封建王朝建立的管理音乐的一个宫廷官署——“乐府”。

The kiwi bird

The kiwi bird is a flightless bird，about the size of a chicken. It sleeps during the day and is active at night­time. It has a long beak that is one­third the length of its body, and its beak actually has nostrils (鼻孔) at the end. The kiwi is the only bird with this feature. Another unique feature of the kiwi is  that it has no tail. It has thick brown hair­like feathers. This bird  has many physical features unlike any other bird on earth.

Kiwi birds have been called a genetic leftover. Their characteristics seem very odd to us probably due to the fact that they haven't evolved much at all. They are suspected to be about 8 million years old. That's 7 million years older than humans. Due to New Zealand's isolated environment, it has been safe from predators(食肉动物) and hasn't needed to do much adapting. They just hang around.

With its long beak, the kiwi digs up and chows down on  worms. A kiwi is almost blind; it can see about six feet at night and around two feet during the day，so when it comes to hunting the kiwi is not well equipped.It uses the nostrils on its  beak to find its food and then picks up the worms with its beak.

The kiwi bird is native of New Zealand.It is the island country's national bird, and is rare anywhere but here and a few Pacific island neighbors. Of course，it is available for viewing at certain zoos.It has stayed in its native land due to the facts that it is an isolated island and that kiwis can't fly.

Kiwi birds are extremely unique in the bird world. Though they are the size of chickens, they lay eggs the size of ostrich eggs, weighing around a pound each.Their enormous eggs are the largest in the bird world, compared to their bodies. These birds were named after their distinctive shrill cry “kee­wee kee­wee”．
