Questions 57 to 61 are based on the following passage.
Lonely people,it seems,are at greater risk than the gregarious (爱交际的)of developing illnesses associated with chronic inflammation (炎症),such as heart disease and certain cancers.A paper published last year in the Public Library of Science,Medicine shows the effect on mortality of loneliness is comparable with that of smoking and drinking after examining the results of 148 previous studies and controlled for factors such as age and pre-existing illness.
Steven Col.e of the University of California,Los Angeles,thinks he may know why this is so.He told the American Association for the Advancement of Science (AAAS) meeting in Washington,D.C.,about his work studying the expression of genes in lonely people.Dr.Cole harvested samples of white blood cells from both lonely and gregarious people.He then analyzed the activity of their genes,as measured by theproduction of a substance called messenger RNA.This molecule carries instructions from the genes telling a cell which proteins to make.The level of messenger RNA from most genes was the same in both types of people.There were several dozen genes,however,that were less active in the lonely,and several dozen others that were more active.Moreover,both the less active and the more active gene types came from a small number of functional groups.
