Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

You can usually tell when your friends are happy or angry by the looks on their faces or by their actions. This is useful because reading their emotional expressions helps you to know how to respond to them. Emotions have evolved to help us respond to important situations and to convey our intentions to others. But does raising the eyebrows and rounding the mouth say the same thing in Minneapolis as it does in Madagascar? Much research on emotional expressions has centered on such questions.

According to Paul Ekman, the leading researcher in this area, people speak and understand substantially the same "facial language". Studies by Ekman's group have demonstrated that humans share a set of universal emotional expressions that testify to the common biological heritage of the human species. Smiles, for example, signal happiness and frowns indicate sadness on the faces of people in such far- flung places as Argentina, Japan, Spain, Hungary, Poland , Sumatra ,the United States, Vietnam, the jungles of New Guinea , and the Eskimo villages north of Artic Circle. Ekman and his colleagues claim that people everywhere can recognize at least seven basic emotions: sadness, fear, anger, disgust, contempt, happiness, and surprise. There are, however, huge differences across cultures in both the context and intensity of emotional displays - the so called display rules. In many Asian cultures, for example, children are taught to control emotional responses - especially negative ones- while many American children are encouraged to express their feelings more openly. Regardless of culture, however, emotions usually show themselves, to some degree , in people's behavior. From their first days of life, babies produce facial expressions that communicate their feelings.

The ability to read facial expressions develops early, too. Very young children pay close attention to facial expressions, and by age five, they nearly equal adults in their skill at reading emotions on people's faces. This evidence all points to a biological underpinning for our abilities to express and interpret a basic set of human emotions. Moreover, as Charles Darwin pointed out over a century ago, some emotional expressions seem to appear across species boundaries. Cross - cultural psychologists tell us that certain emotional responses carry different meanings in different cultures. For example, what emotion do you suppose might be conveyed by sticking out your tongue? For Americans, this might indicate disgust, while in China it can signify surprise. Likewise, a grin on an American face may indicate joy, while on a Japanese face it may just as easily mean embarrassment. Clearly, culture influences emotional expressions.

The word " evolved" is closest in meaning to _________.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

 The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

 On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

 What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

 As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.
