Staying positive through the cold season could be your best defense against getting ill, new study findings suggest.In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition (性格) were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a "positive emotional style" can help ward off the common cold and other illnesses.Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny nose. "People with a positive emotional style may have different immune response to the virus," explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe." Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional trait itself had the effect.For the new study, the researchers had 193 healthy adults with complete standard measures of personality traits, self-perceived health and emotional "style". Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style. The researchers gave them nose drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, or sneezing (打喷嚏) they had, while the researchers collected objective data. Cohen and his colleagues found that based on objective measures of nasal woes (鼻部的不适), happy people were less likely to develop a cold.(1) (单选题)The new study findings in the experiment suggest that _________.A.Being optimistic is more probable to keep healthy.B.Staying positive is more likely to catch cold.C.Having a negative emotion is harmful to the character.D.Having a good disposition is more likely to get ill.(2) (单选题)The phrase "ward off" in Paragraph 2 most probably means "_________".A.set asideB.give inC.shrug offD.keep away(3) (单选题)It can be inferred from Dr. Sheldon Cohen's interpretation that ______________.A.people with a positive emotion are more likely to regard their illness as less serious.B.people with a negative emotion are more likely to boost immune function to the virus.C.people with a positive emotion are more likely to interpret their illness objectively.D.people with a negative emotion are more likely to interpret their illness subjectively.(4) (单选题)It can be learnt from the passage that the benefits of having a positive emotional style are _____________.A.still dubiousB.to be further studiedC.proven by scientific researchD.self-evident(5) (单选题)Which of the following would be the best TITLE for the passage?A.
