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.

Many studies on emotional expressions try to answer the question whether _________.

A. raising the eyebrows has similar meaning to rounding the mouth

B. different cultures have similar emotional expressions

C. rounding the mouth has the same meaning in Minneapolis and Madagascar

D. eyebrow raising means the same in Minneapolis and Madagascar

Belgium is a very old country, with a fascinating mixture of old customs and modern laws. Belgium weddings may be performed as a civil ceremony or as a religious ceremony.

Traditionally, when a couple in Belgium wishes to announce their marriage, the wedding invitations are printed on two sheets of paper, one from the bride's family and one sheet from the groom's family. These wedding invitations symbolize the union of the two families and the partnership of the new union.

An ancient Belgium custom that is designed to unite the two families calls for the bride to stop as she walks up the isle and to hand her mother a single flower. The two then embrace. Then, during the recessional, the bride and groom walk to the groom's mother and the new bride hands her new mother-in-law a single flower and the two of them embrace, symbolizing the bride's acceptance of her new mother.

One of the most important and enduring traditions of the Belgium wedding is for the bride to carry a specially embroidered handkerchief that has her name embroidered on it. After the wedding this handkerchief is framed and hung on the wall in a place of honor. When the next female member of the bride's family is to be wed, the handkerchief is removed from its frame, the new bride's name is embroidered onto it, and it is passed down. The wedding handkerchief is passed from generation to generation, and is considered an important family heirloom.

During the wedding mass, the bride and the groom are enthroned in two large chairs placed near the altar, symbolizing that on this day and in this place they are the king and the queen. At the conclusion of the ceremony, the groom slips the wedding ring onto the third finger of his bride's left hand. The ring, being an endless circle, symbolizes never-ending love, and the third finger of the left hand is believed to hold the vein that travels to the heart, symbolizing love. At the conclusion of the ceremony, the bride and groom share their first kiss as husband and wife. The kiss is considered a symbolic act of sharing each other's spirit as the couple each breathes in a portion of their new mate's soul.

The bridesmaids traditionally take up a collection of coins and as the bride and groom exit the church, the bridesmaids toss the coins to the poor outside the church. Giving gifts of money to the poor helps to insure prosperity for the new bride and groom.

Following the wedding the bride and groom are off on their honeymoon. In ancient times the honeymoon, which was celebrated by the drinking of mead, or honey wine, would last 28 days, one complete cycle of the moon. This was to make sure that the bride's family did not try to steal their daughter back from her new husband.

What does the word "them" in the third paragraph refer to? 

A. the bride and her mother 

B. the bride and the groom 

C.the bride and her mother-in-law 

D. the groom and his mother-in-law

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.

Farming has come a long way since the days of horse-drawn plows, and now it’s heading swiftly into the twenty-first century. Research at Indiana’s Purdue University uses the Navistar Global Positioning System (GPS) to help increase crop yields and reduce chemical use. GPS uses satellite signals to determine location within inches. Under Purdue’s scheme, a farmer out in the field would use a GPS receiver mounted on his vehicle to pinpoint his position. A computer linked to the receiver and programmed with the field’s soil conditions – which can vary widely from one area to another – would tell the farmer precisely where the plant and how much pesticide and fertilizer to use at that specific site. “Currently the number one cost to the famer is chemicals” say Gary Kurtz, a Professor of Agriculture Engineering at Purdue. Site-specific farming can increase yields while reducing chemical use.

But the cost of this new technology may be too high for the small farmer. The cost of taking and testing soil samples every few feet in a farmer’s field is a limiting factor. Soil tests can run $7 to  $8 each. Mark Morgan, assistant Professor of Agriculture Engineering at Purdue and his graduate assistants are working on a sensor to be attached to the front of a farm implement, enabling the farmer to perform his own soil tests on the go.

The expression “run to” is closest in meaning to _______.

A. pay back 

B. amount to

C. Discount

D. cost more

Read the following passage and mark the letter A, B, C or D to indicate the correct answer.

The medieval artists didn’t know about perspective; they didn’t want to make their people look like real, individual people in a real, individual scene. They wanted to show the truth, the eternal quality of their religious stories. So these artists didn’t need to know about perspective.

In the European Renaissance period, artists wanted to show the importance of the individual person and his or her possessions and surroundings. A flat medieval style couldn’t show this level of reality and the artists needed a new technique. It was the Italian artist Brunelleschi who discovered the technique of perspective drawing. At first the artists of the Renaissance only had single-point perspective. Later they realized that they could have two-pointed perspective and still later multi-point perspective.

With two-point perspective they could turn an object (like a building) at an angle to the picture and draw two sides of it. The technique of perspective which seems so natural to us now is an invented technique, a part of the “grammar of painting”. Like all bits of grammar there are exceptions about perspective. For example, only vertical and horizontal surfaces seem to meet on eye level. Sloping roof tops don’t meet on eye level.

For 500 years, artists in Europe made use of perspective drawing in their pictures. Nevertheless, there are a range of priorities that artists give in displaying individual styles. Crivelli wanted to show depth in his picture and he used a simple single-point perspective. Cezanne always talked about space and volume. Van Gogh, like some of the other painters of the Impressionist period, was interested in Japanese prints. And Japanese artists until this century were always very strong designers of “flat” pictures. Picasso certainly made pictures which have volume and depth. However, he wanted to keep our eyes on the surface and to remind us that his paintings are paintings and not illusions.

It is technically easy to give an illusion of depth. However, a strong two dimensional design is just as important as a feeling of depth, and perhaps more important.
