On the provincial level, some women in Canada could vote beginning in 1916. Suffrage expanded to the federal level over the next few years: In 1917 nurses and women in the armed forces could vote, then women whose fathers, husbands, or sons were serving overseas. In 1918 legislation passed expanding suffrage to female citizens excluding Asian-Canadian women and First Nation women, who did not win the right to vote until the 1940s and 1960s, respectively.

Non-indigenous women in Australia got the right to vote beginning in 1895, when the state of South Australia passed colony- and state-wide suffrage, in addition to the right to stand for parliament. In 1899, state suffrage expanded to Western Australia. In 1902, non-indigenous women won the right to vote on the federal level with the passing of the Commonwealth Franchise Act. Indigenous Australians didn't get the federal right to vote until 1962.

 The state of South Australia passed colony- and state-wide suffrage in 1895.

As many as one thousand years ago in the Southwest, the Hopi and Zuni Indians of North America were building with adobe-sun-baked brick plastered with mud.  Their homes looked remarkably like modern apartment houses. Some were four stories high and contained quarters for perhaps a thousand people, along with storerooms for grain and other goods. These buildings were usually put up against cliffs, both to make construction easier and for defense against enemies. They were really villages in themselves, as later Spanish explorers must have realised since they called them "pueblos", which is Spanish for towns. The people of the pueblos raised what are called "the three sisters" - corn,  beans, and squash. They made excellent pottery and wove marvelous baskets, some so fine that they could hold water. The Southwest has always been a dry country, where water is scarce. The Hopi and Zuni brought water from streams to their fields and gardens through irrigation ditches. Water was so important that it played a major role in their religion. They developed elaborate ceremonies and religious rituals to bring rain. The way of life of less - settled groups was simpler and more strongly influenced by nature.

Small tribes such as the Shoshone and Ute wandered the dry and mountainous lands between the Rocky Mountains and the Pacific Ocean. They gathered seeds and hunted small animals such as rabbits and snakes.

In the Far North, the ancestors of today's Inuit hunted seals, walruses, and the great whales. They lived right on the frozen season shelters called igloos built of blocks of packed snow. When summer came, they fished for salmon and hunted the lordly caribou.

The Cheyenne, Pawnee and Sioux tribes, known as the Plains Indians, lived on the grasslands between the Rocky Mountains and the Mississippi River. They hunted bison, commonly called the buffalo. Its meat was the chief food of these tribes, and its hide was used to make their clothing and the covering of their tents and tepees

A pioneering study by Donald Appleyard made the astounding discovery that a sudden increase in the volume of traffic through an area affects people in the way that a sudden increase in crime does. Appleyard observed this by finding three blocks of houses in San Francisco that looked much alike and had the same kind of middle-class and working-class residents, with approximately the same ethnic mix. The difference was that only 2,000 cars a day ran down Octavia Street (LIGHT street, in Appleyard’s terminology) while Gough Street (MEDIUM street) was used by 8,000 cars daily, and Franklin Street (HEAVY street) had around 16,000 cars a day. Franklin Street often had as many cars in an hour as Octavia had in a day.
Heavy traffic brought with it danger, noise, fumes and soot, directly, and trash secondarily. That is, the cars didn’t bring in much trash, but when trash accumulated, residents seldom picked it up. The cars, Appleyard determined, reduced the amount of territory residents felt responsible for. Noise was a constant intrusion into their homes. Many Franklin Street residents covered their doors and windows and spent most of their time in the rear of their houses. Most families with children had already left.
Conditions on Octavia Street were much different. Residents picked up trash. They sat on their front steps and chatted with neighbors. They had three times as many friends and twice as many acquaintances as the people on Franklin.
On Gough Street, residents said that the old feeling of community was disappearing as traffic increaseD. People were becoming more and more preoccupied with their own lives. A number of families had recently moved and more were considering. Those who were staying expressed deep regret at the destruction of their community.

In what order does the author present detailed discussions of the three streets?

Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators. 
Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars. 
Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam. 
Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future. 

In the third paragraph, the word “convert” is closest in meaning to _______ 

Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies. Curiously enough, the first American silver coins, issued in 1794, had fifteen stars because by that time Vermont and Kentucky has joined the Union. At that time it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee in 1796, for example, some varieties of half dimes, dimes, and half-dollars were produced with sixteen starts. As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from A798 on were issued with only thirteen stars-one for each ofthe original colonies. Due to an error at the mint, one variety of the A828 half cent was issued with only twelve stars. There is also a variety of the large cent with only A2 stars, but this is the result of a die breakand is not a true error.

The word “bore” in line 2 is closest in meaning to ________ .

Read the passage below and choose one correct answer for each question.

It has been thought that women are the second class in citizen, and men are the first. There is not a real equality of opportunity for men and women. Years ago, people were living in a man-dominated society. Women had to obey their husbands and fathers absolutely. Women's place was in the kitchen and women's work was housework. In many places, women were not even allowed to go to school. Women had no rights, even the right to choose husband for themselves. Men usually occupied high positions in society so they thought they were more intelligent than women. Men often considered women as their property. Sometimes, they were mistreated by their husbands and suffered the problem as a fate. Many parents did not even want to daughters.

Despite the progress, there remain outdated beliefs about women's roles, traditionally passed down from generation to generation. Men are commonly seen as the strong bodies, bread-winners in the family and key leaders in society, while women are restricted to being housewives and child bearing and care, and housework such as washing and cooking.

According to social surveys, many women in the 21st century still have to work over 12 hours a day including working in offices and doing countless household chores without any help from their husbands. In some regions, the labor of women is not recognized despite the hardships they endure to support the whole family. Moreover, women are the direct victims of family violence, especially in rural areas.

Thanks to the women's liberation movement, nowadays women have proved that they are equal to men in every aspect. An average woman has weaker muscles than an average man but she may be as intelligent as he is. Women can do everything that men can, and women can do one thing that no man can: they produce children.

Until the 19th century, the denial of equal rights to women met with only occasional protest and drew little attention from most people. Because most women lacked the educational and economic resources that would enable them to challenge the prevailing social order, women generally accepted their inferior status as their only option. At this time, women shared these disadvantages with the majority of working class men, as many social, economic, and political rights were restricted to the wealthy elite.In the 19th century, as governments in Europe and North America began to draft new laws guaranteeing equality among men, significant numbers of women – and some men – began to demand that women be accorded equal rights as well.
At the same time, the Industrial Revolution in Europe and North America further divided the roles of men and women. Before the Industrial Revolution most people worked in farming or crafts-making, both of which took place in or near the home. Men and women usually divided the numerous tasks among themselves and their children. Industrialization led male workers to seek employment outside of the home in factories and other large-scale enterprises. The growing split between home and work reinforced the idea that women’s “rightful place” was in the home, while men belonged in the public world of employment and politics.
Organized efforts by women to achieve greater rights occurred in two major waves. The first wave began around the mid-19th century, when women in the United States and elsewhere campaigned to gain suffrage that is, the right to vote. This wave lasted until the 1920s, when several countries granted women suffrage

Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.
Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist- skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated.
Having adapted to their austere environment, they are as healthy as animals anywhere else in the word. The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun- baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

Man can hardly understand why many animals live their whole life in the desert, as________.

In addition to their military role, the forts of the nineteenth century provided numerous other benefits for the American West. The establishment of these posts opened new roads and provided for the protection of daring adventurers and expeditions as well as established settlers. Forts also served as bases where enterprising entrepreneurs could bring commerce to the West, providing supplies and refreshments to soldiers as well as to pioneers. Posts like Fort Laramie provided supplies for wagon trains traveling the natural highways toward new frontiers. Some posts became stations for the pony express; still others, such as Fort Davis, were stagecoach stops for weary travelers. All of these functions, of course, suggest that the contributions of the forts to the civilization and development of the West extended beyond patrol duty.
 Through the establishment of military posts, yet other contributions were made to the development of western culture. Many posts maintained libraries or reading rooms, and some – for example, Fort Davis – had schools. Post chapels provided a setting for religious services and weddings. Throughout the wilderness, post bands provided entertainment and boosted morale. During the last part of the nineteenth century, to reduce expenses, gardening was encouraged at the forts, thus making experimental agriculture another activity of the military. The military stationed at the various forts also played a role in civilian life by assisting in maintaining order, and civilian officials often called on the army for protection.
 Certainly, among other significant contributions the army made to the improvement of the conditions of life was the investigation of the relationships among health, climate, and architecture. From the earliest colonial times throughout the nineteenth century, disease ranked as the foremost problem in defense. It slowed construction of forts and inhibited their military functions. Official documents from many regions contained innumerable reports of sickness that virtually incapacitated entire garrisons. In response to the problems, detailed observations of architecture and climate and their relationships to the frequency of the occurrence of various diseases were recorded at various posts across the nation by military surgeons.

   Over the past 600 years, English has grown from a language of few speakers to become the dominant language of international communication. English as we know it today emerged around 1350, after having incorporated many elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking and diplomacy.

   Currently, about 80 percent of the information stored on computer systems worldwide is English. Two thirds of the world’s science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are nonnative speakers, constituting the largest number of non-native users than any other language in the world..

Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology.
Deep inside the brain there is a "clock" that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the circadian clock (from the Latin, circa "about" + dies "day"). This body clock programmes us to be sleepy twice a day, between 3-5 a.m and again between 3-5 p.m.
Afternoon tea and siesta times are all cultural responses to our natural biological sleepiness in the afternoon.
One of the major causes of the travelers' malady known as jet lag is the non-alignment of a person's internal body clock with clocks in the external world. Crossing different time zones confuses the circadian clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjust to a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may be on a different schedule altogether.
Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to shrink our day. That is why traveling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quantity and quality than eastward flights.
When flying west, you are "extending" your day, thus traveling in the natural direction of your internal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency. One of the more common complaints of travelers is that their sleep becomes disrupted. There are many reasons for this: Changing time zones and schedules, changing light and activity levels, trying to sleep when your body clock is programmed to be awake, disruption of the internal circadian clock and working longer hours.
Sleep loss, jet lag and fatigue can seriously affect our ability to function well. Judgment and decision-making can be reduced by 50%, attention by 75 percent, memory by 20 percent and communication by 30 percent.
It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination's schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone.

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: 
Leonardo da Vinci was born on April 15,1452, in the small Tuscan town ofVinci, near Florence. He was the son of a wealthy Florentine public official and a peasant woman. In the mid-1460s, the family settled in Florence, where Leonardo was given the best education that Florence could offer. He rapidly advanced socially and intellectually. He was handsome, persuasive in conversation, and a fine musician and improviser. About in 1466 he apprenticed as a studio boy to Andrea Del Verrocchio. In Verrocchio's workshop, Leonardo was introduced to many activities, from the painting of altarpieces and panel pictures to the creation of large sculptural projects. In 1472, he was entered in the painter's guild of Florence, and in 1476, he was still mentioned as Verrocchio's assistant. In Verrocchio's Baptism of Christ, the kneeling angel at the left of the painting is by Leonardo.
In 1478, Leonardo became an independent master. His first commission, to paint an altarpiece for the chapel of the Palazzo Vecchino, the Florentine town hall, was never executed. His first large painting, The Adoration of the Magi, left unfinished, was ordered in 1481 for the Monastery of San Donato a Scopeto, Florence. Other works ascribed to his youth are the so-called Benois Madonna, the portrait Ginerva de' Bend, and the unfinished Saint Jerome.
In 1482, Leonardo's career moved into high gear when he entered the service of the duke of Milan, Ludovico Sforza, having written the duke an astonishing letter in which he stated that he could build portable bridges; that he knew the techniques of constructing bombardments and of making cannons; that he could build ships as well as armored vehicles, catapults, and other war machines; and that he could execute sculpture in marble, bronze, and clay. He served as a principal engineer in the duke’s numerous military enterprises and was so active also as an architect. In addition, he assisted the Italian mathematician Luca Pacioli in the celebrated work Divina Proportione.

What can be inferred about Andrea Del Verrocchio?

As many as one thousand years ago in the Southwest, the Hopi and Zuni Indians of North America were building with adobe-sun-baked brick plastered with mud.  Their homes looked remarkably like modern apartment houses. Some were four stories high and contained quarters for perhaps a thousand people, along with storerooms for grain and other goods. These buildings were usually put up against cliffs, both to make construction easier and for defense against enemies. They were really villages in themselves, as later Spanish explorers must have realised since they called them "pueblos", which is Spanish for towns. The people of the pueblos raised what are called "the three sisters" - corn,  beans, and squash. They made excellent pottery and wove marvelous baskets, some so fine that they could hold water. The Southwest has always been a dry country, where water is scarce. The Hopi and Zuni brought water from streams to their fields and gardens through irrigation ditches. Water was so important that it played a major role in their religion. They developed elaborate ceremonies and religious rituals to bring rain. The way of life of less - settled groups was simpler and more strongly influenced by nature.
Small tribes such as the Shoshone and Ute wandered the dry and mountainous lands between the Rocky Mountains and the Pacific Ocean. They gathered seeds and hunted small animals such as rabbits and snakes.
In the Far North, the ancestors of today's Inuit hunted seals, walruses, and the great whales. They lived right on the frozen season shelters called igloos built of blocks of packed snow. When summer came, they fished for salmon and hunted the lordly caribou.
The Cheyenne, Pawnee and Sioux tribes, known as the Plains Indians, lived on the grasslands between the Rocky Mountains and the Mississippi River. They hunted bison, commonly called the buffalo. Its meat was the chief food of these tribes, and its hide was used to make their clothing and the covering of their tents and tepees.

Which of the following is TRUE of the Shoshone and Ute?

Rock carvings suggest that Stone Age people were hunting whales for food as early as 2,200 B.C. Such (31)______ hunting is still practised today in a number of societies including the Inuit people of Greenland and North America. Whaling became big (32)_____________ from the seventeenth century as the demand for whale bone and whale oil rose, and the humpback and sperm whales were hunted in increasing large number. (33)_________ just as stocks of these species began to fall, the explosive harpoon gun was invented. This weapon, together with the development of steam-powered ships, enable the whaler to hunt the fast moving fin and blue whales. In 1905, the whaling (34)____________ moved the water of Antarctica. The introduction of massive factory ships enabled the whales to be processed at sea. As a result, the blue whale had virtually disappeared by the 1950s. In 1946, The International Whaling Commision was established to maintain the declining whale populations. Quotas were set but these were often ignored and the numbers continued to fall. Hunting of many species continued until 1986 when the IWC finally responded to international (35)____________ and a band on commercial whaling was introduced.

Just as optical fibers have transformed communication, they are also revolutionizing medicine. These ultrathin, flexible fibers have opened a window into the living tissues of the body. By inserting optical fibers through natural openings or small incisions and threading  them along the body's established pathways, physicians can look into the lungs, intestines,  heart and other areas that were formerly inaccessible to   them.
The basic fiber-optics system is called fiberscope, which consists of  two  bundles  of fibers. One, the illuminating bundle, carries light to the tissues. Is is coupled to  a  high- intensity light source. Light enters the cores of the high-purity silicon glass and travels along the fibers. A lens at the end of the bundle collects the light and  focuses  it into the other  bundle, the imaging bundle. Each fiber in the bundle transmits only a tiny fraction of the total image. The reconstructed image can be viewed through an eyepiece or displayed on a television screen.
During the last five years, improved methods of fabricating optical fibers have led to a reduction in fiberscope diameter and an increase in the number of fibers, which in turn has increased resolution. Optical fibers can also be used to deliver laser light. By use of laser beams, physicians can perform surgery inside the body, sometimes eliminating the need for invasive procedures in which healthy tissue must be cut through to reach the site of disease. Many of these procedures do not require anesthesia and can be performed in a physician's office. These techniques have reduced the risk and the cost of medical care.
