【简答题】
Money spent on advertising is money spent as well any I know of. It serves directly to assist a rapid distribution of goods at reasonable prices, thereby establishing a firm home market and so making it possible to provide for export at competitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it ensures an increased need for labor, and is therefore an effective way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television license would need to be doubled, and travel by bus or tube would cost 20 percent more. And perhaps most important of all, advertising provides a guarantee of reasonable value in the products and services you buy. Apart from the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for mercifully the public has the good sense not to buy the inferior article more than once. If you see an article consistently advertised, it is the surest proof I know that the article does what is claimed for it, and that it represents good value. Advertising does more for the material benefit of the community than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television personality declare that he was against advertising because it persuades rather than informs. He was drawing excessively fine distinctions. Of course advertising seeks to persuade. If its message were confined merely to information---and that in itself would be difficult if not impossible to achieve, for even a detail such as the choice of the color of a shirt is subtly persuasive---advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television personality wants.

【单选题】如图所示,某同学不慎将圆柱形木塞(木塞的中心有一小孔)卡于圆柱形金属筒的靠近封闭端底部的位置,为了拿出木塞,该同学将金属筒倒立过来(开口端向下),使其由静止开始沿竖直方向向下做加速运动(加速度值大于重力加速度值),此过程中木塞始终相对金属筒静止,当金属筒速度达到一定值时,金属筒的开口端撞击到桌面,且其速度立即减为零。此后木塞沿金属筒壁继续竖直向下运动,木塞运动到金属筒口边缘时速度恰好减为零。若木塞...
