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 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 trou- bled by a scratchy throat or runny nose.
"People with a positive emotional style may have different immune responses 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 susceptible to catching 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 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 nasal drops containing either a cold virus or a particular flu virus.Over the next six days,the volunteers reported on any aches,pains,sneezing or congestion they had,while the researchers collected objective data,like daily mucus production.Cohen and his colleagues found that based on objective measures of nasal woes,happy people were less likely to develop a cold.
选项 People with a sunny disposition are immune to illness.A:RightB:Wrong C:Not mentioned
答案B
解析由文章第一段第二句的后半部分“… researchers found that people with a generally sunny disposition were less likely to fall ill.”可知，性格阳光的人不太容易生病，但并不等于对疾病免疫。 由文章第四段的“…happier people seemed less susceptible to catching a cold…”可知，快乐的人更加不容易患感冒。 由文章的最后一句可知，Cohen和他的同事是依据客观数据得出的实验结论，而非主观测验。 由文章第五段第二句可知，这些研究对象中既包括积极乐观的人，也包括悲观的人。 第六段第一句中提到，研究者给这些志愿者一些含有感冒病毒或某种流感病毒的滴鼻剂，而不是预防感冒的药品，故选B。 由文章第五段第二句可知，那些快乐、有活力且随和的人被认为具有积极的情绪。故本题正确。 关于家庭和个人情绪类型的关系在文章中并未提及，因此本题答案为C。
