铜奔马正名

作为中国旅游标志的东汉铜奔马是1969年在甘肃武威出土的,据云当时被定名为“马踏飞燕”,也有学者引经据典,将其定名为“马超龙雀”。最后可能因为众说纷纭,无奈之下取名为“铜奔马”。“铜奔马”一名虽然简明扼要,但有马无燕,未惬人意。

最近有人在《光明日报》上撰文,更考定此物应名“飞廉铜马”。其根据有二:一是《后汉书·董卓传》中有“飞廉铜马之属”的记载,载是“《三才图会》里的飞廉图,便是一只飞鸟”。愚意此说更属不妥。首先,《三才图会》一书乃明朝嘉靖、万历间人所作,且《四库提要》认为其中采摭浩博,然间有冗杂虚构之病。其次,关于“飞廉”,注家多有出入。《墨子·耕柱》云:“夏后启使飞廉折金于山川。”《史记:秦本纪》云:“飞廉善走,父子俱以材力事殷纣。”以上两书显然认为飞廉是人。但是《淮南子·椒真训》高诱注:“飞廉,兽名,长毛有翼。”《楚辞·离骚》王逸注:“飞廉,风伯也。”洪兴祖补注:“飞廉,神禽,能致风气。”可见飞廉到底是人是神,是兽是禽,古人也无定论。两汉之间神话颇多,汉代画像石中常有人骑神兽,驾神龙升天的景象,亦有骑马的形象,但神兽归神兽,马归马,在这些图案中各有其形。武威铜马是一件写实的作品,马足下的飞鸟亦然,所以很难将其与神话中的飞廉相提并论。至于《后汉书•董卓传》所说,当是飞廉归飞廉,铜马归铜马,非指一物,故丈后有“之属”一词。

然而,武威铜马足下确有一鸟,其象征之意为人所关注。一提到马,人们很快想到奔腾如飞,而飞燕的速度同样也是毋庸置疑的。历朝多有以燕喻良马之诗文,如南朝沈约诗有“紫燕光陆离”句,注:“紫燕,良马也。”梁朝简文帝诗云:“紫燕跃武,赤兔越空。”两句中赤兔指良马,紫燕亦指良马。李善注谢灵运诗云:“文帝自代还,有良马九匹,一名飞燕骝。”在古代,武威铜马足下的飞燕无疑是用来比喻良马之神速,这种造型让人一看便知其意,所以铜马应直截了当取名为“紫燕骝”或“飞燕骝”,此名恰合古意,最为雅致贴切。

以下不属于作者为铜奔马正名的原因的一组是()。

A.作为中国旅游标志的东汉铜奔马,其名称一直众说纷纭

B.“马踏飞燕”“马超龙雀”两名跟铜奔马造型相合,但未被采用

C.“铜奔马”一名中虽然有奔马,但是没有飞燕,不能令人满意

D.“飞廉铜马”一名,比起“铜奔马”“马踏飞燕”等更逊一筹

We might marvel at the process made in every field of study, but the method of testing a person’s knowledge and ability remain as primitive as ever they were. It really is extraordinary that after all these years educationists have still failed to devise anything more efficient and reliable than examinations.
41. ______
They may be a good means of testing memory, or the knack of working rapidly under extreme pressure, but they can tell you nothing about a person’s true ability and aptitude.
42. ______
Your whole future may be decided in one fateful day. It doesn’t matter that you weren’t feeling very well, or that your mother died. Little things like that don’t count: the exam goes on. no one can give of his best when he is in mortal terror, or after a sleepless night, yet this is precisely what the examination system expects him to do. The moment a child begins school, he enters a world of vicious competition where success and failure are clearly defined and measured. Can we wonder at the increasing number of "dropouts": young people who are written off as utter failures before they have even embarked on a career Can we be surprised at the suicide rate among students
43. ______
Examinations do not motivate a student to read widely, but to restrict his reading; they do not enable him to seek more and more knowledge, but induce cramming. They lower the standards of teaching, for they deprive the teacher of all freedom. Teachers themselves are often judged by examination results and instead of teaching their subjects, they are reduced to training their students in exam techniques which they despise. The most successful candidates are not always the best educated; they are best trained in the technique of working under duress.
44. ______
Examiners are only human. They get tried and hungry; they make mistakes. Yet they have to mark stacks of hastily scrawled scripts in a limited amount of time. They work under the same sort of pressure as the candidates. And their word carries weight. After a judge’s decision you have the right of appeal, but not after an examiner’s.
45. ______
Is it cynical to suggest that examinations are merely a profitable business for the institutions that run them This is what it boils down to in the last analysis. The best comment on the system is this illiterate message recently scrawled on a wall: "I were a teenage drop-out and now I am a teenage millionaire."
[A] A good education should, among other things, train you to think for yourself. The examination system does anything but that. What has to be learnt is rigidly laid down by a syllabus, so the students are encouraged to memorize.
[B] The results on which so much depends are often nothing more than a subjective assessment by some anonymous examiner.
[C] Examinations can be taken as a test of a student’s knowledge about a particular subject which would tell the student where he stands among others, and how much he knows and how much he ought to know.
[D] As anxiety-makers examinations are second to none. That is because so much depends on them. They are the mark of success or failure in our society.
[E] The student appearing for the exam takes it under extreme tension and pressure because he knows that he has only one chance to prove his worth and if he fails, he will be left behind for the rest of his life.
[F] For all the pious claim that examinations test what you know, it is common knowledge that they more often do the exact opposite.
[G] There must surely be many simpler and more effective ways of assessing a person’s true abilities.
