[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.
Which of the following may be concluded from the passage 查看材料
A.The experiment was performed at the University of Surrey in early 2013.
B.Body-clock genes are associated with heart disease, cancer and Type 2 diabetes.
C.Sleep restrictions may contribute to disease like diabetes, insomnia, and heart disease.
D.7.5-8 hours' sleep pattern makes little difference compared with 6.5-7 hours' sleep pattern.

Wrongly Convicted Man and His Accuser Tell Their Story
NEW YORK NY,January 5,2010,St.Martin's Press has announced the release of the paperback edi- tion of Picking Cotton,a remarkable true story of what novelist John Grisham calls an"account of violence, rage,redemption（救赎）,and,ultimately,forgiveness."
The story began in 1987,in Burlington,North Carolina,with the rape of a young white college student named Jennifer Thompson.During her ordeal,Thompson swore to herself that she would never forget the face of her rapist,a man who climbed through the window of her apartment and assaulted her brutally._______(46)When the police asked her if she could identify the assailant（袭击者）from a book of mug shots,she picked one that she was sure was correct and later she identified the same man in a lineup.
Based on her convincing eyewitness testimony,a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms.Cotton's lawyer appealed the decision,and by the time of the appeals hearing,evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton,an imprisoned criminal named Bobby Poole.______(47)Jennifer Thompson looked at both men face to face,and once again said that Ronald Cotton was the one who raped her.
Eleven years later , DNA evidence completely exonerated（证明……清白）Cotton and just as unequivocally（明确地）convicted Poole , who confessed to the crime._________ ( 48 ) " The man I was so sure I had never seen in my life was the man who was inches from my throat,who raped me,who hurt me, who took my spirit away,who robbed me of my soul,"she wrote."And the man I had identified so surely on so many occasions was absolutely innocent."_______(49)Remarkably,both were able to put this tragedy behind them,overcome the racial barrier that divided them,and write a book,which they have subtitled "Our memoir of injustice and redemption."
Nevertheless,Thompson says,she still lives"with constant pain that my profound mistake cost him so dearly._______(50)"
_______(47)
A.Another trial was held.
B.I cannot begin to imagine what would have happened had my mistaken identification occurred in a capital case.
C.Thompson was shocked and devastated.
