2009年10月24日，为营救两名落水少年，湖北长江大学10多名大学生手拉手扑进江中。两名落水少年得救了，而陈及时、何东旭、方招三名大学生却在激流中英勇牺牲。下列对此事件的评价正确的是 A．大学生不懂得珍爱自己的生命 B．只有见义勇为，才能实现生命的价值 C．当他人遭遇困境时，应及时伸出援助之手 D．为了挽救他人的生命，只能不顾个人安危A messy desk can actually lead people towards clearer thinking, say researchers from Germany．The researchers found in a series of linked studies - using a messy desk and a messy shop front - that people actually thought more clearly when all around was chaos, as they sought to simplify the tasks at hand. Visual and mental clutter（阻塞） forces human beings to focus and think more clearly. Famous thinkers and writers such as Albert Einstein and Roald Dahl have been notorious（声名狼藉的） for their untidy desks.“Messy desks may not be as detrimental（有害的） as they appear to be, as the problem-solving approaches they seem to cause can improve work efficiency or increase employees' creativity in problem solving,” say the authors.“Business and government managers often promote 'clean desk' policies to avoid disorganized offices and messy desks, for the purpose of boosting work efficiency and productivity,” writes lead researcher Jia Liu of the University of Groningen in a paper published in the Journal of Consumer Research.“This practice is based on the conventional wisdom that a disorganized and messy environment can clutter one's mind and complicate one's judgments.”“However, not all evidence supports this conventional link between a messy environment and a messy mind.”The scientists tested people's response in various 'messy' environments - including a messy shop front, a disorganized desk, and even a work environment where a language task 'reminded' people of messiness. The authors found in the series of six studies people tended towards simplicity in their thinking.“They categorized （分类） products in a simpler manner, were willing to pay more for a T-shirt that shows a simple-looking picture, and sought less variety in their choices.” said the researchers1.The purpose of the first two paragraphs is to show that _____．A.A messy desk cannot contribute to clearer thinkingB.People thought more clearly about a messy desk and a shop frontC.People will feel confused when all around are chaosD.People manage to simplify the tasks in messy environments2.Why does the author take Albert Einstein as an example?A.to support the idea that clearer thinking comes from messy environment．B.to tell the fact that Einstein was known for his untidy desks．C.to stop us from learning from Albert Einstein．D.to call on us to develop a good habit．3.How do people look at messy environment according to the conventional wisdom?A.Messy environment will create clearer thinking．B.Messy environment will simplify one' s judgment．C.Messy environment can promote work efficiency．D.Messy environment can block one' s mind．4.What does the last paragraph imply?A.People believe messy environment creates clearer thinking．B.People sought more simplicity in the choices．C.People were not willing to choose those complicated products．D.Not all the people accept messy environment and complicated things
