阅读理解You’resittingonthetrainhomeandth

阅读理解 You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired. This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words. Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(内部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you’re sitting— it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”So, what lessons can we learn from this? “ Spend time with happy people— otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”1.According to Hugo Critchley, ________.A.emotions are as visible as facial expressionsB.we yawn more frequently when we have a coldC.emotions are connected with states of internal responsesD.the change of blood pressure is not linked with the change of emotions.2.The underlined word “synchronies” in Paragraph 4 means “_____”.A.move slowlyB.change rapidlyC.relax temporarilyD.respond accordingly3.From the passage we can learn ________.A.sadness is as contagious as happinessB.anger is less contagious than friendlinessC.surprise is more contagious than smileD.surprise is the most contagious among emotions4.Which of the following statements is true according to the passage?A.Emotions have delicate influence on fellow humans.B.Children like copying the actions of the fellow humans.C.Scientists are still confused about contagious yawningD.People tend to communicate more with body language.

CDBA解析本文是一篇说明文（科技文），说明的是：快乐的情绪可以影响周围的人。1.根据第三段的“Emotions are closed linked with states of internal responses,”得知C正确。2.根据第四段的“Our bodies synchronise and when we like the other Person, we even copy his behavior. Next time you chat with a friend, take note of how you’re sitting-it's pretty likely that you will be the same.”得知选D。3.根据第二段的最后一句得知微笑的传染力要比惊讶和生气的传染力明显，所以B正确，ACD错。4.根据第二段的第一句得知人们的情绪受同类人的影响，所以A 正确，C错误。而BD显然是错的。说明文（科技文）是高考的热点，是词汇量比较大的阅读项目。
