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? Itś 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. {TS}What kind of relation is directly discussed in the passage? A 、 Sleeping hours and changes of genes. B 、 Sleeping hours and diseases. C 、 Changes of genes and diseases. D 、 Genes and health. 2、What can we learn about Professor Derk-Jan Dijkś experiment? 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. 3、Which of the following may be concluded from the passage? 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. 4、Which of the following can be inferred from the findings of the sleep research? A 、 When there is a sleep restriction, genes to do with cell repair and replacement function less. B 、 In a sleep, several hundred genes change in the amount. The more changes, the worse results. C 、 When genes are up regulated, they do good to health; when genes arc down regulated, they do harm to health. D 、 Eight hours of sleep a day can be beneficial to our health in that it looks after our genes. 5、根据下面资料，回答{TSE}题 In New York, Ma Yun witnessed the Alibaba Group opening on the New York stock exchange with the largest initial public offering (IPO, 新 股发行) in American history. "Alibaba, the worldś largest Internet commerce company makes China equal to the US in the rapidly increasing global competition for technological innovation and economic transformation" commented the South China Morning Post. It has also made Ma Chinaś richest man with a fortune of around $25 billion (153 billion yuan), reported Reuters. Itś reported that Maś rags-to-riches journey is just as spectacular as his Internet Empire. Ma failed the national college entrance exams twice before he was finally in Hangzhou Normal University on his third attempt and failed in finding a s
