,Even though ulcers（溃疡） appear to run in families, lifestyle plays扮演 more of a role角色 than genetic（基因的） factors in causing the illness, according to a report in the April 13th Journal of Internal Medicine. In particular, smoking and stress in men and the regular use of pain-releasing medicines in women were linked with an increased risk of developing an ulcer.…………………………………………………………….1. The passage argues 指出thatA. Ulcers are related to genes.B. Ulcers are chiefly related to lifestyle.C. Ulcers appear in men and women.D. Ulcers are caused by bacteria infection.注解：在读段落第一句时，如果是状语从句中心应在主句上，从句可以不读。例如上句“尽管溃疡是以家庭形式出现，而生活方式在引起疾病方面比基因起到更重要的作用。”因此该文的中心应该是生活方式而不是家族遗传。应选C。这里为什么选C,而不选B啊?
