C
You're walking down the street,thinking about your own business when a stranger passes by.He doesn't say anything at all,but he gives you a smile.In a moment and almost unwillingly,you're doing the same thing.You just can't help it and you catch his smile.For some unknown reason,when we see someone smile,we just can't stop ourselves doing the same thing.
In honour of World Smile Day(the first Friday in __ c to ber),it's the time we get real answers to this matter.Is smiling contagious(感染性的)？
Well,a study in the journal Trends in Cognitive Sciences gives the answer “ yes ".As part of the research,social psychologists(心理学家)looked into why we often copy(模仿)people's facial expressions when we talk to them.

So the reas Son we smile back when someone smiles at us is that we want to fee 1 the same way as that person.However,not everyone can do this.During the research,the psychologists find people with some diseases can't copy others' facial expressions.They know someone is smiling but they cannot smile back.
