　　Strong emotional bonds between mothers and infants increase children’s willingness to explore the world—an effect that has been observed 67 the animal kingdom, in people, monkeys and even spiders. The more secure we are in our 68 to Mom, the more likely we are to try new things and take risks. Now researchers are discovering that this effect continues into adulthood. A 69 reminder of Mom’s touch or the sound of her voice on the phone is

　　70 to change people’s minds and moods, 71 their decision making in measurable ways.

　　In a study 72 online in April in Psychological Science, undergraduate business students had to choose between safe bets and risky gambles—a bond with a guaranteed 4 percent yearly

　　73 or a riskier stock option, for example. In half the cases, the experimenters patted the students 74 on the back of the shoulder for about one second 75 providing verbal instructions about the study. Both male and female students who were touched by a female experimenter were 76 more likely to choose the risky alternative 77 were those who had not been touched or were patted by male experimenters. The reassuring（寬慰的）touch of a woman may have induced early associations, 78 the same openness to exploration that is observed in young children of 79 mothers, explains Jonathan Levav, a business professor at Columbia University and lead author of the study.

　　To further 80 that a woman’s touch links feelings of security 81 risk taking, the researchers asked a 82 group of undergraduates to make financial decisions after a writing exercise. Half of them wrote about a time they felt secure and supported, whereas the 83 half wrote about feeling insecure and alone. Evoking (喚起) a 84 of insecurity made students in the latter group 85 receptive to the gentle shoulder pats from female experimenters and much more willing to take a risk—just as a child leaving for a field trip might steal one last reassuring hug 86 Mom before stepping on the bus.

　　All about My Mother: How Touch Helps Us Take Risks，作者Ferris Jabr。原文共五段，495字，題目選取了原文前三段并做了細微修改，共345字。主要講述的是母親與嬰兒間形成的情感紐帶會影響孩子探索世界的行為。這是一篇典型的議論文，第一段第一句給出論點，指出母親與嬰兒間形成的情感紐帶會影響人們的行為，接著在第二段和第三段，通過兩個已經發表的文章中的實驗來證明這一觀點。
