问答题Possession for its own sake or in competition with the rest of the neighborhood would have been Thoreau’’s idea of the low levels. The active discipline of heightening one’’s perception of what is enduring in nature would have been his idea of the high. What he saved from the low was time and effort he could spend on the high. Thoreau certainly disapproved of starvation, but he would put into feeding himself only as much effort as would keep him functioning for more important efforts.Effort is the gist of it. There is no happiness except as we take on life-engaging difficulties. Short of the impossible, as Yeats put it, the satisfaction we get from a lifetime depends on how high we choose our difficulties. Robert Frost was thinking in something like the same terms when he spoke of the pleasure of taking pains . The mortal flaw in the advertised version of happiness is in the fact that it purports to be effortless.We demand difficulty even in our games. We demand it because without diffculty there can be no game. A game is a way of making something hard for the fun of it. The rules of the game are an arbitrary imposition of difficulty. When someone ruins the fun, he always does so by refusing to play by the rules. It is easier to win at chess if you are free, at your pleasure, to change the wholly arbitrary rules, but the fun is in winning within the rules. No difficulty, no fun.

问答题中国科技馆的诞生来之不易。与国际著名科技馆和其他博物馆相比，它先天有些不足，后天也常缺乏营养，但是它成长的步伐却是坚实而有力的。它在国际上已被公认为后起之秀。世界上第一代博物馆属于自然博物馆，它是通过化石、标本等向人们介绍地球和各种生物的演化历史。第二代博物馆属于工业技术博物馆，它所展示的是工业文明带来的各种阶段性结果。这两代博物馆虽然起到了传播科学知识的作用，但是，它们把参观者当成了被动的旁观者。世界上第三代博物馆是充满全新理念的博物馆。在这里，观众可以自己去动手操作，自己细心体察。这样，他们可以更贴近先进的科学技术，去探索科学技术的奥妙。中国科技馆正是这样的博物馆。它汲取了国际上一些著名博物馆的长处，设计制作了力学、光学、电学、热学、声学、生物学等展品，展示了科学的原理和先进的科技成果。
