How many different emotions (情感) do you think you can communicate to people with your face? Do you have the same facial expressions as people from different cultures? Read this to find out what scientists have just discovered about this topic.

New research suggests that there are only four basic facial expressions of emotion. However, how these expressions are interpreted (理解) might depend on where you are from. Research by scientists from the University of Glasgow has challenged the traditional view of how the face expresses emotions. Until now, it was widely believed that six basic emotions — happiness, sadness, fear, anger, surprise and disgust (厌恶) — were expressed and recognized across different cultures. However, the University of Glasgow's work now suggests that the human face only has four basic expressions of emotion. This is because some pairs of emotions are impossible to distinguish (区分). Fear and surprise, for example, both share wide open eyes. The facial

expressions for anger and disgust also look the same.

So if our faces are only able to express four basic emotions, how do we communicate a much more complex (复杂的) variety of feelings? The study found that the way expressions are interpreted is different in different cultures. Looking at how people from the East and West look at different parts of the face during facial expression recognition, scientists found that although there are some common features across cultures, the six basic facial expressions of emotion are not recognized universally.

What interests people about the cross­cultural aspect of the research? “This work leads to understanding which emotions we share and appreciating our differences.”

语篇解读：本文为说明文。新的研究表明，人类只有四种基本的面部表情，而不是六种。 1．What did the University of Glasgow find? A．Facial expressions express emotions. B．Six basic emotions can be recognized. C．Some basic facial expressions are unusual. D．Some of the six facial expressions are similar.

解析：选D 推理判断题。根据第二段的“This is because some pairs of emotions are impossible to distinguish (区分)”可知，六种基本表情里面有一些是类似的。

2．Which group may be the four basic facial emotions? A．Sadness, fear, anger and surprise. B．Anger, sadness, fear and happiness. C．Happiness, surprise, sadness and fear. D．Disgust, happiness, anger and sadness.

解析：选B 推理判断题。根据第二段最后两句话，再对比之前提到的六种表情，可推断出新的研究提出的四种基本表情。

3．What can be inferred from the text? A．Basic facial expressions are not universal. B．People find it hard to communicate more feelings. C．People from the West have more facial expressions. D．We can't express more feelings with four expressions.

解析：选A 推理判断题。根据第三段的“... the six basic facial expressions of emotion are not recognized universally”可知，基本的面部表情并不是通用的，文化不同，所表达的意思也不同。

A shopping center in Brazil is growing vegetables on its rooftop using waste collected from the mall's restaurants.The garden is on the roof of the Eldorado shopping

Workers grow different kinds of fruits and vegetables on the rooftop garden, including tomatoes, lettuce (生菜) and eggplant.The fruits and vegetables grown there provide free food for the employees.Mall officials also hope to reduce the amount of waste that would end up in a garbage dump.This, they hope, will reduce carbon gases entering the atmosphere.

He says, “We weigh the material and add enzymes (酶) that remove bacteria, reduce humidity (湿度) and accelerate decomposition (分解)．This is how we turn organic waste into organic compost.”

Officials at the shopping center want to save as much waste as possible.So, they held workshops for employees to learn how to best collect waste from their stores.Neide Lopes is a food court worker.She says it is helpful to put in the extra work.

“The program is active and creative, and they distribute the produce among us, so it's very good.It is a way of reducing waste, and we receive food that we don't have to pay for, and that's the best part！”

Mall employees say the project reuses waste food to make food and reduces the shopping center's carbon footprint (碳排放量) at the same time.

语篇解读：幸福是什么？作者在文中告诉我们幸福是善良，是爱，是无私。 1．a 空格后面的house是可数名词，根据句意“她独自一人居住在一个小房子里”可知用a表示泛指，意为“一个”。

2．died 根据本句中的时间状语years ago可知，要用一般过去时，故填died。 3．with 根据句意“但她经常面带微笑地帮助别人”，可知填with，表示“带着”。 4．to clean be the first to do sth.表示“第一个做某事”，序数词后要用不定式作定语，所以填to clean。

5．laughter and连接并列结构，and后面的love是名词，所以此处也应该用名词，laugh的名词形式是laughter，是不可数名词，故填laughter。

6．noisily 所填词作状语修饰动词talk，所以用副词，故填noisily。

7．but 空格前后都是完整的句子，所以要用并列连词。根据句意“可能他们在那时候会感到幸福，但是他们永远也不会得到真正的幸福，因为他们已经失去了人格。”可知，前后分句之间为转折关系，所以用but连接。

8．have lost 根据本句中“already”判断此处是现在完成时，主语是they，故填have lost。 9．It 分析句子成分可知，此处缺少主语，指代上一句的“happiness”，故填It。本句句意为“它意味着善良、爱和无私。”

10．bringing 分析句子结构可知，此处缺少主语，所以用动名词形式，即bringing。
