5、Smoking Can Increase Depressive Symptoms in Teens While some teenagers may puff on cigarettes to \-medicate\against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens.
\observational study is one of the few to examine the perceived emotional benefits of smoking among teens,\says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto.\Although cigarettes may appear to have self-medicating effects or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. \ As part of the study, some 662 high school teenagers completed up to 20 questionnaires ____ their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were

measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things. \who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked,\says co-researcher Jennifer O＇Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. \who reported emotional benefits from smoking are at higher risk of developing depressive symptoms.\
The association between depression and smoking exists principally among teens that use cigarettes to feel better. \＇s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke,\ 【单选题】 A.beside B.beyond

6、The Ideal Husband
Science now might be able to explain women＇s fascination with Brad Pitt＇s face and George Clooney＇s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are
13
perceived as better long-term mates.
In the study by Daniel Kruger at the US＇s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.
Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.
But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine ____ men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.
The study was published in the December issue of the US journal Personal Relationships.
Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible for the development of masculine facial features and other sexual
14
characteristics. It has been found to affect the body＇s ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.
However, increased testosterone has also been linked to cheating and violence in relationships. So, these men might produce high quality offspring, but they don＇t always make great parents or faithful mates, Kruger says.
The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours. 【单选题】
