“世间万物，变动不居”。“明者因时而变，知者随事而制。这说明①运动是绝对的静止是相对的②一切是运动变化的③离开运动谈物质是唯心主义④规律是客观的A. ①④ B. ①② C. ②③ D. ③④ 答案：【答案】B【解析】题目中，观点“世间万物，变动不居”认为世界万物都是处于运动之中的，“明者因时而变，知者随事而制”意思是指聪明的人根据时期的不同而改变，有大智慧的人会伴随着事物的发展而制定相应的管理方法，也体现了事物是变化发展的观点，这说明一切是运动变化的，运动是绝对7、Burning the midnight oil before an exam or interview has an opposite effect according to a research which found that sleep is necessary for memories to be “downloaded” into the brain. “A good night’s sleep within 30 hours of trying to remember a new task is a necessary condition of having good recall（回忆）in the weeks ahead,” scientists have found. “We think that getting that first night’s sleep starts the process of memory consolidation（加强）,” said Robert Stickgold, a sleep researcher at Harvard Meidical School who conducted the latest study. “It seems that memories are normally washed out of the brain unless some process nails them down. I feel uncertain that sleep is one of those things that do the nailing down,” Professor Stickgold said. Professor Stickgold’s team trained the 24 people to tell direction of three diagonal bars（斜线）shown for a sixtieth of a second on a computer screen full of horizontal stripes（水平线）. Half the subjects were kept awake that night, while the others slept. Both groups were allowed to sleep for the second and third nights so make up for any differences in tiredness between the volunteers（志愿者）. Those who slept the first night were much better at remembering the task while the second ground showed no improvement in spite of enjoying two nights of catch-up sleep. A further study by scientists at the Medical University at Lubeck Germany showed that memories are laid down in two stages during the night. The first is during the deep, so-called “slow wave” sleep, which usually takes place in the first half of the night. The second, and less important stage happens during the period of dreaming or “rapid eye movement (REM)”. When people don’t sleep well in the first half of the night, their memory consolidation is almost the same as having no sleep at all. 1.
