[不定项选择题]根据下面资料，回答题 I′ve often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes on and bad genes off. In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only "reads" the part of this handbook it needs at any given moment. Can sleep affect how a gene reads instructions It′s a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours. Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less. Sleep restriction (six and a half to seven hours a night) changed 380 genes. Of these,220 genes were down regulated (their power was reduced), while 160 were up regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes. One of the most downgraded genes is that which has a role in controlling insulin and is linked to diabetes and insomnia. The most upgraded gene is linked to heart disease. So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little. The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes. What can we learn about Professor Derk-Jan Dijk′ s experiment 查看材料
A.The experiment was carried out to find the answer to how genes affect sleep.
B.The experiment took a period of more than two weeks to reach a conclusion.
C.His volunteers were divided into two groups with two different sleeping patterns.
D.Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping.

[单选题]You don't know what you've got till it's gone,Joni Mitchell rold us.So now that the 2018 Nobel Prize in Literature will be postponed-it seems worth asking what,exactly,the prize gives us.For decades,the choices of the Swedish Academy have failed to provoke much interest from American publishers and readers.This i.s not just because American readers are resistant to fiction in translation,as publishers often complain.On the contrary,over the last two decades,many foreign writers have made a major impact on American literature.But then,the failure of the Swedish Academy to reflect the actual judgment of literary history is nothing new.If you drew a Venn diagram showing the winners of the Nobel Prize in one circle and the most influential and widely read 20th-century writers in the other,their area of overlap would be surprisingly small.Does this mean that a different group of critics and professors in a bigger,more diverse country woulcl have done a better job at picking the winners?Very possibly.In the mind of the general public,the Nobel basically descends from the sky to bless the winner.But it is nothing more or less than the decision of a particular group of readers,with their own strengths and weaknesses.And the problem with the Nobel Prize in Literature goes deeper.No matter who is in the room where it happens,the Nobel Prize is based on the idea that merit can best be determined by a small group of specialists.This may make sense for the prizes in the sciences,since those fields are less than penetrable to anyone but fellow practitioners.Even in the sciences,however,there is a growing sense that the tradition of awarding the prize to just one or two people distoris the way modern science is actually practiced today:Most important discoveries are the work of teams,not of individual geniuses brooding in isolation.Literature is at least produced by individual authors;but in this case,the Nobel's reliance on seemingly expert judgment runs into a different problem.For literature is not addressed to an audience of experts;it is open to the judgment of every reader.Nor is literature proZressive,with new discoveries replacing old ones:Homer is just as groundbreaking today as he was 2,500 years ago.This makes it impossible to rank literary works according to an objective standard of superiority.Good criticism helps people to find the books that will speak to them,but it doesn't attempt to simply name"the most outstanding work,"in the way the Nobel Prize does.A book earns the status of a classic,not because it is approved by a committee or put on a syllabus,but simply because a lot of people like it for a long time.Literary reputation can only emerge on the free market,not through central planning. Which of the following is true of the Nobel Prize in Literature according to Para.3?
A.Its judges are narrow-minded.
B.lts value is overstated by the public.
C.Its decision is interfered by amateurs.
D.Its rewards for the winners are falling.
