【正确答案】 B

【答案解析】[听力原文]
   We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways.
   It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns.
   Fear is another emotion that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like "he went pale and began to tremble" suggests either that the man was very afraid or he has just got a very big shock. However, "he opened his eyes wide" is used to suggest anger in Chinese whereas in English it means surprise. In Chinese "surprise" can be described in a phrase like "they stretched out their tongues!" Sticking out your tongue in English is an insulting gesture or expresses strong dislike.
   Even in the same culture, people differ in ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people's faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do.
   Q: When dogs, tigers and human show their teeth, how are they most likely feeling?
我们用语言和姿势来表达情感，但问题在于，这些语言和姿势可以有不同的理解方式。
   微笑在任何语言里意义都是相同的，这是事实。大笑或哭泣亦是如此。表达同一种情感时，不同动物间有着惊人的相似。例如，当狗、老虎和人类生气时经常会露出牙齿。这很可能是因为他们天生拥有这些行为模式。
   恐惧是另外一种在全世界范围内表现方式大致相同的情绪。在汉语和英语文学里，“他脸色发白并开始颤抖”这一表达要么表示他非常害怕，要么表示他刚刚大吃了一惊。然而，“他睁大眼睛”在汉语里表示生气，而在英语里表示惊讶。在汉语里像“他们吐舌头”这样的话可用来表示“惊讶”。在英语里吐舌头是一个无礼的举动或用来表达强烈的厌恶。
   即使在同一种文化中，人与人之间理解和表达情感的能力也是有差别的。在美国进行的多次实验表明，女性通常比男性更善于识别恐惧、生气、爱和幸福等人的面部表情。另外一些研究表明，老年人通常比年轻人更容易识别和理解人的肢体语言。
   快速浏览各题选项，根据前两题各选项中表示情绪的词以及后两题中的facial expressions、gestures、feelings推测，本文的内容很可能与情绪、表情及姿势等有关，具体细节需要进一步分析各个选项。
   ①四项均为形容词。
   ②四项描述的是四种不同的情绪或感受。
   结论：本题很可能考查与情绪或感受有关的内容。听音时，需重点关注此类形容词，然后根据问题做出进一步的判断。
   本题是细节题。题目问的是当狗、老虎和人露出牙齿的时候，最可能表达的是一种什么样的情绪文中提到，在表达同一种情感时，不同动物间有着惊人的相似之处。然后举例说明，当狗、老虎和人露出牙齿的时候，都是生气的表现，故本题选B。
