Before photography was invented in 1839, painted portraits, and engravings based on them, were one of the few ways to record likenesses. From the Colonial era through the 1820s, portraiture was the most widely practiced genre of American art, and it continued to be a significant form through the 19th century. The demand for likenesses was incessant, and portraiture was often the primary source of income for artists. Artists frequently made portraits of famous people to attract interest and potential patrons. For example, in 1834 Chester Harding painted frontiersman Davy Crockett, then a member of the U.S. House of Representatives, for display in his Boston gallery.

A consistent belief through most of the 18th and 19th centuries was that character could be read from a person's face, or the bumps on his or her head, or from facial expressions, and that portraits should convey these indicators of character. These theories of physiognomy and phrenology have since been debunked, but they were important considerations in depicting the nation's leaders, since such portraits were often made for posterity. Most people had only one portrait painted in their lifetime, if at all, so artists were selected with great care, and expectations were high.

Before the 1840s, American portraiture was influenced primarily by English techniques, poses, compositions and gestures, and many artists received at least part of their training in England. Even canvas sizes followed the British example. Portraits made on commission were priced according to canvas size and the materials and labor involved.

In the late 19th century as European portraitists began traveling to the United States to acquire commissions from the growing upper class, American artists increasingly felt they needed to train abroad in order to succeed at home. Paris continued to be the main lure. as painters such as Eakins, Whistler, Beaux and Sargent went to study there. Some of America's best-known portraitists, in fact, became expatriates.

 Fingerprints might have proved that the suspect was at the scene of the crime.

 

 

A. The suspect might be at the scene of the crime though his fingerprints might have not been proved. 

B. It was possible that fingerprints proved the presence of the suspect at the scene of the crime. 

C. Fingerprints are proved to have belonged to the suspect at the scene of the crime. 

D. Without doubt, the suspect was at the scene of the crime due to hid fingerprints.

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.

          Very few people in the modern world obtain their food supply by hunting and gathering in the natural environment surrounding their homes. This method of harvesting from nature's provision is the oldest known subsistence strategy and has been practised for at least the last two million years. It was, indeed, the only way to obtain food until rudimentary farming and the domestication of wild animals were introduced about 10,000 years ago.

          Because hunter-gatherers have fared poorly in comparison with their agricultural cousins, their numbers have dwindled, and they have been forced to live in marginal environments, such as deserts and arctic wastelands. In higher latitudes, the shorter growing seasons have restricted the availability of plant life. Such conditions have caused a greater dependence on hunting, and on fishing along the coasts and waterways. The abundance of vegetation in the lower latitudes of the tropics, on the other hand, has provided a greater opportunity for gathering a variety of plants. In short, the environmental differences have restricted the diet and have limited possibilities for the development of subsistence societies.

          Contemporary hunter-gatherers may help us understand our prehistoric ancestors. We know from the observation of modern hunter-gatherers in both Africa and Alaska that a society based on hunting and gathering must be very mobile. While the entire community camps in a central location, a smaller party harvests the food within a reasonable distance from the camp. When the food in the area has become exhausted, the community moves on to exploit another site. We also notice seasonal migration patterns evolving for most hunter-gatherers, along with a strict division of labor between the sexes. These patterns of behavior may be similar to those practised by mankind during the Paleolithic Period.

Which of the following would serve as the best title of the passage? 

A. Hunter-gatherers: Always on the Move 

B. Evolution of Humans' Farming Methods 

C. Hunter-gatherers and Subsistence Societies 

D. A Brief History of Subsistence Farming

A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometers in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word “radar”, in fact, gets its name from the term “radio detection and ranging”. “Ranging” is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, tracking ships at sea, and for tracking weather systems and storms. 

 Which of the following would most likely be the topic of the next paragraph?  

A. A history of flying.

B. Other uses of radar. 

C. The technology used by pilots. 

D. Uses of some technology.

          Human Nutrition is the study of how food affects the health and survival of the human body. Human beings require food to grow, reproduce, and maintain good health. Without food, our bodies could not stay warm, build or repair tissue, or maintain the heartbeat. Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fueled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates, proteins, fats, vitamins, minerals, and water.

          When we eat a meal, nutrients are released from food through digestion. Digestion begins in the mouth by the action of chewing and the chemical activity of saliva, a watery fluid that contains enzymes, certain proteins that help break down food. Further digestion occurs as food travels through the stomach and the small intestine, where digestive enzymes and acids liquefy food and muscle contractions push it along the digestive tract. Nutrients are absorbed from the inside of the small intestine into the bloodstream and carried to the sites in the body where they are needed. At these sites, several chemical reactions occur, which ensures the growth and function of body tissues. The parts of foods that are not absorbed continue to move down the intestinal tract and are eliminated from the body as feces.

          Once digested, carbohydrates, proteins, and fats provide the body with the energy it needs to maintain its many functions. Scientists measure this energy in kilocalories, the amount of energy needed to raise one kilogram of water one degree Celsius. In nutrition discussions, scientists use the term calorie instead of kilocalorie as the standard unit of measure in nutrition.

          Nutrients are classified as essential or nonessential. Nonessential nutrients are manufactured in the body and do not need to be obtained from food. Examples include cholesterol, a fatlike substance present in all animal cells. Essential nutrients must be obtained from food sources, because the body either does not produce them or produces them in amounts too small to maintain growth and health. Essential nutrients include water, carbohydrates, proteins, fats, vitamins, and minerals.

          An individual needs varying amounts of each essential nutrient, depending upon such factors as gender and age. Specific health conditions, such as pregnancy, breast-feeding, illness, or drug use, make unusual demands on the body and increase its need for nutrients. Dietary guidelines, which take many of these factors into account, provide general guidance in meeting daily nutritional needs.           

       From “Human Nutrition” by Worthington-Roberts, Bonnie, Microsoft ® Student 2009.

 

A. general guidance

B. unusual demands

C. dietary guidelines

D. nutritional needs
