河北省唐山市2018-2019学年高一下学期英语期末考试英语试卷
Most people are good at recognizing the universal facial expressions of our emotions 一 anger, joy, sadness, etc., which present a lot of emotional information. In fact, there are less obvious facial expressions called micro-expressions (MEs). Huma n beings often show them and communicate their private thoughts to others unconsciously (无意识的).What's more, people cannot hide them, including the experienced ones. And MEs have universality (普遍性), regardless of one's age, religion or culture.
All the findings lead to the possibilities of MEs' wide use in different fields, where people can use MEs to understand other people's true feelings, thoughts, or beliefs. Police can use MEs to detect unnatural behavior. Teachers can recognize unease in students and give a more careful explanation. Businessmen can use expressions of happiness to determine when they have given a suitable price. When one wants to be able to do what are mentioned above, it is useful to be able to read MEs.
However, MEs are difficult to read, because they are unconscious, and occur sometimes as fast as one-tenth of a second or even one-fifteenth of a second. At present, even highly trained persons are not always able to notice them. Some people do see something that has changed on the face, but they don't know exactly what it is that has changed. Since the human recognition accuracy (精准)is so low, a possible method for spotting MEs would be very precious.
