We might marvel at the progress made in every field of study, but the methods 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 device anything more efficient and reliable than examinations. For all the pious claim that examinations text what you know, it is common knowledge that they more often do the exact opposite. 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. As anxiety-makers, examinations are second to none. That is because so much depends on them. They are the mark of success of failure in our society. 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 ‘drop-outs’: 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? 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 student is encouraged to memorize. 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 freedoms. 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 the best trained in the technique of working under duress. The results on which so much depends are often nothing more than a subjective assessment by some anonymous examiner. Examiners are only human. They get tired 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. There must surely be many simpler and more effective ways of assessing a person’s true abilities. 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 are a teenage millionaire.’

植物睡眠之迷 自然界有许多植物的叶子会运动,比如含羞草、合欢等豆科植物白天张开叶子,晚上会合上叶子“睡眠”;捕绳草的叶子能闭合起来,捕食苍蝇等昆虫。像含羞草、合欢等植物的这种“睡眠运动”自古以来就受到人们的关注,可是植物为什么会睡眠,却一直是个不解之迷。 18世纪,法国生物学家德梅兰把含羞草放到光线照不到的洞穴里,发现它的叶子依然以24小时为周期开合。这说明含羞草体内存在一种不受外界光线等环境因素影响的“生物钟”。19世纪,达尔文在《植物的运动本领》中说,植物在晚上闭合叶子睡眠是“为了保护自己免受夜晚低温之害”。20世纪80年代,德国希尔德奈特的研究报告指出,叶子的开合是由一种称为“膨压素”的植物激素控制的。此后,日本上田实等人从植物中抽出包含数千种化合物的萃取物,最后成功分离出两种活性物质,一种是可使植物叶子闭合的“安眠物质”,另一种是可使植物叶子张开的“兴奋物质”。 植物睡眠之谜之所以长期不得其解,就是因为此前没有人想到使叶子开合的竟是两种不同的生理活性物质。人们进一步了解到,豆科植物叶子下珠的安眠物质是一种含葡萄糖的配糖体,白天配糖体水解,安眠物质浓度降低,夜晚配糖体重新合成,兴奋物质浓度相对降低,而配糖体的合成分解是由叶下珠体内的生物钟控制的。相反,铁扫帚的兴奋物质是配糖体,在夜晚配糖体水解,兴奋物质浓度降低,叶子随之闭合。如果用人工合成的半乳糖代替葡萄糖,由于半乳糖在铁扫帚体内不会水解,反而成为一种睡眠阻断剂,使铁扫帚始终不能睡眠,以致两个星期之后因缺水枯萎而死。 解开植物睡眠之谜,将为某种“绿色”农药的诞生铺平道路。目前的除草剂还无法只让田菁等豆科杂草枯萎而不损害豆科作物。研究人员已经人工合成了使田菁失眠的睡眠阻断剂,实验结果是田菁第三天就整株枯死。由于这种阻断剂只对田菁起作用,因此不会影响大豆的生长。
【題組】6.从原文看,以下研究最能揭开“植物睡眠之谜”的一项是
(A)德梅兰提出含羞草体内存在着不受外界因素影响的“生物钟”。
(B)达尔文提出植物在晚上睡眠是为了保护自己免受夜晚低温之害。
(C)希尔德奈特提出植物睡眠是由植物体内的“膨压素”控制的。
(D)上田实等人提出植物体内存在着使叶子闭合的“安眠物质”。
