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 from 38 to 42.   Body postures and movements are frequently indicators of self-confidence, energy, fatigue, or status. Cognitively, gestures operate to clarify, contradict, or replace verbal messages. Gestures also serve an important function with regard to regulating the flow of conversation. For example, if a student is talking about something in front of the class, single nods of the head from the teacher will likely cause that student to continue and perhaps more elaborate. Postures as well as gestures are used to indicate attitudes, status, affective moods, approval, deception, warmth, arid other variables related to conversation interaction.   The saying “A picture is worth a thousand words” well describes the meaning of facial expressions. Facial appearance – including wrinkles, muscle tone, skin coloration, and eye color-offers enduring cues that reveal information about age, sex, race, ethnic origin, and status. A less permanent second set of facial cues-including length of hair, hairstyle, cleanliness, and facial hair-relate to an individual’s idea of beauty. A third group of facial markers are momentary expressions that signal that cause changes in the forehead, eyebrows, eyelids, cheeks, nose, lips, and chin, such as raising the eyebrows, wrinkling the brow, curling the lip.   Some facial expressions are readily visible, while others are fleeting. Both types can positively or negatively reinforce the spoken words and convey cues concerning emotions and attitudes. A nod of the head from the teacher will likely ask his student to_________what he is saying.

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 from 35 to 42.   Long before they can actually speak, babies pay special attention to the speech they hear around them. Within the first month of their lives, babies’ responses to the sound of the human voice will be different from their responses to other sorts of auditory stimuli. They will stop crying when they hear a person talking, but not if they hear a bell or the sound of a rattle. At first, the sounds that an infant notices might be only those words that receive the heaviest emphasis and that often occur at the ends of utterances. By the time they are six or seven weeks old, babies can detect the difference between syllables pronounced with rising and falling inflections. Very soon, these differences in adult stress and intonation can influence babies’ emotional states and behavior. Long before they develop actual language comprehension, babies can sense when an adult is playful or angry, attempting to initiate or terminate new behavior, and so on, merely on the basis of cues such as the rate, volume, and melody of adult speech.   Adults make it as easy as they can for babies to pick up a language by exaggerating such cues. One researcher observed babies and their mothers in six diverse cultures and found that, in all six languages, the mothers used simplified syntax, short utterances and nonsense sounds, and transformed certain sounds into baby talk. Other investigators have noted that when mothers talk to babies who are only a few months old, they exaggerate the pitch, loudness, and intensity of their words. They also exaggerate their facial expressions, hold vowels longer, and emphasize certain words.   More significant for language development than their response to general intonation is observation that tiny babies can make relatively fine distinctions between speech sounds. Other words, babies enter the world with the ability to make precisely those perceptual discriminations that are necessary if they are to acquire aural language.   Babies obviously derive pleasure from sound input, too: even as young as nine months they will listen to songs or stories, although the words themselves are beyond their understanding. For babies, language is a sensory-motor delight rather than the route to prosaic meaning that it often is for adults. What does the passage mainly discuss?

Read the following passage and mark the letter A, 8, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.   In 1826, a Frenchman named Niepce needed pictures for his business. He was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.   The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything clearly, even the smallest details. This kind of photograph was called a daguerreotype.   Soon, other people began to use Daguerre’s process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities, and mountains.   In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple and photographers had to carry lots of film and processing equipment. However, this did not stop photographers, especially in the United States. After 1840, daguerreotype artists were popular in most cities.   Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were lifelike and full of personality. Brady was also the first person to take pictures of a war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.   In the 1880s, new inventions began to change photography. Photographers could buy film ready-made in rolls, instead of having to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive.   With a small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends, and favorite places. They called these pictures “snapshots”.   Documentary photographs became popular in newspapers in the 1890s. Soon magazines and books also used them. These pictures showed true events and people. They were much more real than drawings.   Some people began to think of photography as a form of art. They thought that photography could do more than show the real world. It could also show ideas and feelings, like other art forms. (From "Reading Power” by Beatrice S. Mikulecky and Linda Jeffries) Matthew Brady was well-known for _____________

Read the following passage and mark the letter A, B, C or B on your answer sheet to indicate the correct answer to each of the questions from 30 to 37.   Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route Line by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes.   These trails incorporate no directional information and may be followed by other ants in either direction. Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. The vapor of the evaporating pheromone over the trail guides an ant along the way,  and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail. According to the passage, the highest amount of pheromone vapor is found

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 from 67 to 76. Ralph Earl was born into a Connecticut farm family in 1751. He chose early to become a painter and looked for what training was available in his home state an in Boston. Earl was one of the first American artists to paint landscapes. Among his first paintings were scenes from the Revolutionary war battles of Lexington and Concord In 1778 Earl went to London to study with Benjamin West for four years. When Earl returned to the United States, he was jailed for fourteen months for outstanding debts. While still a prisoner, he painted portraits of some of New York City's most elegant society women and their husbands. After his release, he took up the trade of itinerant portrait painter, working his way through southern New England and New York. He didn't flatter his subjects, but his portrait show a deep understanding of them; perhaps he had sprung from the same roots. Among Earl's most famous paintings is his portrait of Justice Oliver Ellsworth and his wife, Abigail. To provide counterpoint to the severity of the couple, he accurately details the relative luxury of the Ellsworth's interior furnishings. The view through the window behind them shows sun lit fields, well-kept fences, and a bend of the Connecticut River. One of Earl's paintings is something of anomaly. Reclining Hunter, which many years was attributed to Thomas Gainsborough, shows a well-dressed gentleman resting beneath a tree. In the foreground, he displays a pile of birds, the results of a day's hunt. The viewer can also see a farmer's donkey lying in the ground, another of the hunter's victims. This outrageously funny portrait couldn't have been commissioned - no one would have wanted to be portrayed in such an absurd way. However, this painting uncharacteristically shows Earl's wit as well as his uncommon technical skills. The word itinerant is closest in meaning to which of the following?

In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space. The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail. The word “intermittently” in line 4 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 from 67 to 76. Ralph Earl was born into a Connecticut farm family in 1751. He chose early to become a painter and looked for what training was available in his home state an in Boston. Earl was one of the first American artists to paint landscapes. Among his first paintings were scenes from the Revolutionary war battles of Lexington and Concord In 1778 Earl went to London to study with Benjamin West for four years. When Earl returned to the United States, he was jailed for fourteen months for outstanding debts. While still a prisoner, he painted portraits of some of New York City's most elegant society women and their husbands. After his release, he took up the trade of itinerant portrait painter, working his way through southern New England and New York. He didn't flatter his subjects, but his portrait show a deep understanding of them; perhaps he had sprung from the same roots. Among Earl's most famous paintings is his portrait of Justice Oliver Ellsworth and his wife, Abigail. To provide counterpoint to the severity of the couple, he accurately details the relative luxury of the Ellsworth's interior furnishings. The view through the window behind them shows sun lit fields, well-kept fences, and a bend of the Connecticut River. One of Earl's paintings is something of anomaly. Reclining Hunter, which many years was attributed to Thomas Gainsborough, shows a well-dressed gentleman resting beneath a tree. In the foreground, he displays a pile of birds, the results of a day's hunt. The viewer can also see a farmer's donkey lying in the ground, another of the hunter's victims. This outrageously funny portrait couldn't have been commissioned - no one would have wanted to be portrayed in such an absurd way. However, this painting uncharacteristically shows Earl's wit as well as his uncommon technical skills. Which of the following could be substituted for outstanding without changing the meaning of the sentence?
Read the following passage and mark the letter A, B, C or B on your answer sheet to indicate the correct answer to each of the questions from 30 to 37.   Many ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route Line by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes.   These trails incorporate no directional information and may be followed by other ants in either direction. Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth. The vapor of the evaporating pheromone over the trail guides an ant along the way,  and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space.

It then swings back to the right, and so weaves back and forth down the trail. What does the passage mainly discuss?
