第二卷（共35分） 第四部分：写作（共两节，满分35分） 任务型读写（共10小题；每空1分，满分10分） 阅读下列短文，根据所读内容在文章后的表格中填入恰当的单词。注意：表格中的每个空格只填1个单词 Can the thought of loved ones help reduce pain? This may indicate the importance of social relationships and staying socially connected. A study was recently conducted by researchers at the University of California in Los Angeles. In the study, the researchers asked 25 women to participate who had boyfriends with whom they had been in a good relationship for more than six months. The women received painful heat stimuli(刺激)to their forearms while they went through a number of different conditions. In one set of conditions, they viewed photographs of their boyfriend, a stranger and a chair. “When the women were just looking at pictures of their partner, they actually reported less pain to the heat stimuli than when they were looking at pictures of an object or pictures of a stranger, ” said study co-author Naomi Eisenberger, director of UCLA’s Social and Affective Neuroscience Laboratory, “Thus, the mere reminder of one’s partner through a simple photograph was capable of reducing pain.” In another set of conditions, each woman held the hand of her boyfriend, the hand of a male stranger and a squeeze ball. The study found that when women were holding their boyfriends’ hands, they reported less physical pain than when they were holding a stranger’s hand or a ball while receiving the same amount of heat stimulation. “This changes our idea of how social support influences people,” Eisenberger said. “This study proves how much of an impact our social ties can have on our experience and fits with other work emphasizing the importance of social support for physical and mental health,” Eisenberger added. The researchers advised that the next time people are going through a stressful or painful experience, if they cannot bring a loved one with them, a photo may do.
