When they see other students doing better than them, they usually believe that those students have a higher lQ and that there is nothing they can do to change facts. However new research into EQ suggests that success is not simply the result of a high lQ. 转折词之后 段首或文章中间 find/found show/showed suggest/suggested reveal/revealed prove/proved imply/implied believe However suggests 研究性说明文做题步骤 02 03 题目定主旨 圈出关键词 读题目 圈关键 抓题眼 对原文 定位题干关键词 回归文章找依据 01 04 动词定位法 位置定位法 找结论 定主旨 分辨选项细微差别 识别干扰错误项 辨选项 比细节 Step1 找结论定主旨 Step2 读题目圈关键 Step3 抓题眼对原文 Step4 辨选项比细节 How much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled (贴标签) with emissions (排放物) data? Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out. Study participants view a carbon footprint label as similar to labels that have appeared on some existing products. The label displays the carbon dioxide emissions related to their production, transportation, usage and disposal (处理), thus showing the buyer the likely effect on climate change of buying a particular product. In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price. In a second set of studies, the team found that emissions related to usage were most important to consumers followed by the transportation and disposal stages. The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's life cycle because it is outside the consumer's control. That is, the participants felt they were less responsible for carbon emitted during producing process. Consumers value recycling a product, but the researchers found that, overall, the consumers would prefer producers to offset (补偿) carbon emissions rather than have to address the problem directly themselves. Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products. "We find that participants not only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain.They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice.

In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny character were less likely to fail 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 illness. “People with a positive emotional style may have different immune（免疫的）responses to the virus,” explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. Cohen and his colleagues has found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional quality itself had the effect. For the new study, the researchers had 193 healthy adults complete standard measures of personality qualities, physicals 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（敌意的）had a negative style. Afterwards, the researchers gave them nose drops containing either a cold virus or a particular flu virus that causes flu-like symptoms. Over the next six days, the volunteers reported on any aches, pains, sneezing they had. Cohen and his colleagues found that happy people were less likely to develop a cold. What`s more, when happy folks did develop a cold, their symptoms were less severe than expected based on objective measures. In contrast, people with negative characters were not at increased risk of developing a cold based on objective measures, though they did tend to get down about their symptoms. “We find that it`s really positive emotions that have the big effect,” Cohen said, “not the negative ones.”So can a bad-tempered person fight a cold by deciding to be happy?
