【正文】 ith their parents. D． Kids from Canada， France and Italy have closer ties with their moms. D 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(基因 ) on and had genes off. In the first half of 2020, 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 geic 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 DerkJan 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 pare 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 380genes. Of these, 220 genes were down regulated (their power was increased). Those affected included bodyclock genes which are linked to diabetes(糖尿病 ). One of the most downgraded genes is that which has a role in controlling insulin(胰島素 ) and is linked to diabetes and insomnia(失眠 ). 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. 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. and health. can we learn about Professor DerkJan Kijk’ s 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. of the following may be concluded from the passage? A. The experiment was performed at the University of Surrey in early 2020. B. Bodyclock 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. － 8 hours’ sleep pattern makes little difference pared with － 7 hours’ sleep pattern. 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。 17. Where does the speaker?s friend live？ A. In Atlanta. B. In Chicago. C. In San Francisco. 18. What is the speaker?s job? A. An artist. B.
