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.

Read the passage carefully and choose the correct answer:
Today, more and more women are actively participating in social activities both in urban and rural areas. Specifically, they have shined brightly in even many fields commonly regarded as the man's areas such as business, scientific research and social management. In some areas, women even show more overwhelming power than men. The image of contemporary Vietnamese women with creativeness, dynamism, success has become popular in Vietnam's society. The fact reveals that the gender gap has been remarkably narrowed and women enjoy many more opportunities to pursue their social careers and obtain success, contributing to national socio-economic development. 
According to Ms, Le Thi Quy, Director of the Gender/and Development Research Centre under the University of Social Sciences and Humanities, Hanoi National University, gender equity in Vietnam has reached a high level over the past decade. The rate of Vietnamese women becoming National Assembly members from the 9th term to the 11th term increased 8.7%, bringing the proportion of Vietnamese women in authority to 27.3%, the highest rate in Southeast Asia. There is no big gap in the level of literacy and schooling between men and women. Women account for about 37% of university and college graduates, 19.9% of doctoral degree holders and 6.7% of professors and associate professors. 
The legitimate rights of women and children are ensured more than ever before with more complete legal documents including laws, conventions and national action plans, among which the laws on "gender equity" mark a turning-point in the empowerment of women. 
Mass media also highlights the continued success of women in every field and honors their great importance in modern society, helping to do away with outdated perceptions about traditional women's duties. Many projects on reproductive health care, children protection, and family income improvement jointly conducted by various mass organizations, state agencies and non-governmental organizations have created favorable conditions for women to become involved.

Which is not mentioned in the text as a project to create condition for Vietnamese women?

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 NOT mentioned by the author as a dwelling place  of early North America?

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 following questions.

Bees, classified into over 10,000 species, are insects found in almost every part of the world except the northernmost and southernmost regions. One commonly known species is the honeybee, the only bee that produces honey and wax. Humans use wax in making candles, lipsticks, and other products, and they use honey as food. While gathering the nectar and pollen with which they make honey, bees are simultaneously helping to fertilize the flowers on which they land. Many fruits and vegetables would not survive if bees did not carry the pollen from blossom to blossom.

Bees live in a structured environment and social structure within a hive, which is a nest with storage space for the honey. The different types of bees each perform a unique function. The worker bee carries nectar to the hive in a special stomach called a honey stomach. Other workers make beeswax and shape it into a honeycomb, which is a waterproof mass of six-sided compartments, or cells. The queen lays eggs in completed cells. As the workers build more cells, the queen lays more eggs.

All workers, like the queen, are female, but the workers are smaller than the queen. The male honeybees are called drones; they do no work and cannot sting. They are developed from unfertilized eggs, and their only job is to impregnate a queen. The queen must be fertilized in order to lay worker eggs. During the season when less honey is available and the drones are of no further use, the workers block the drones from eating the honey so that they will starve to death.

The word “species” in the first sentence probably means ______.

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.

Which of the following is the most likely inference about the decision to promote gardening at forts?

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 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, how are ants guided by trail pheromones?'

Any list of the greatest thinkers in history contains the name of the brilliant German physicist Albert Einstein. His theories of relativity led to entirely new ways of thinking about time, space, matter, energy, and gravity. Einstein's work led to such scientific advances as the control of atomic energy, even television as a practical application of Einstein's work. In 1902 Einstein became an examiner in the Swiss patent office at Bern. In 1905, at age 26, he published the first of five major research papers. The first one provided a theory explaining Brownian movement, the zig-zag motion of microscopic particles in suspension. The second paper laid the foundation for the photon, or quantum, theory of light. In it he proposed that light is composed of separate packets of energy, called quanta or photons, that have some of the properties of particles and some of the properties of waves. A third paper contained the "special theory of relativity" which showed that time and motion are relative to the observer, if the speed of light is constant and the natural laws are the same everywhere in the universe. The fourth paper was a mathematical addition to the special theory of relativity. Here Einstein presented his famous formula, E = m(cc), known as the energy mass equivalence. In 1916, Einstein published his general theory of relativity. In it he proposed that gravity is not a force, but a curve in the space-time continuum, created by the presence of mass. Einstein spoke out frequently against nationalism, the exalting of one nation above all others. He opposed war and violence and supported Zionism, the movement to establish a Jewish homeland in Palestine. When the Nazis came to power in 1933, they denounced his ideas. He then moved to the United States. In 1939 Einstein learned that two German chemists had split the uranium atom. Einstein wrote to President Franklin D. Roosevelt warning him that this scientific knowledge could lead to Germany developing an atomic bomb. He suggested the United States begin its own atomic bomb research.

"Since the 1940s, most international women’s rights efforts have been organized by the Commission on the Status of Women (CSW), an office established in 1947 by the United Nations (UN). The Commission is the only existing intergovernmental body that issues reports on and recommendations for the promotion of women’s political, social, economic, and cultural rights. The CSW also acts as an advocate for women’s rights and can urge immediate international action in cases of severe violations of women’s rights.
 The UN encouraged equality in the workplace for men and women when it sponsored the Convention Concerning Equal Remuneration for Men and Women Workers for Work of Equal Value in 1953 and the Convention Concerning Discrimination in Respect of Employment and Occupation in 1960. Over 100 countries ratified these measures. In 1975 the UN launched the Decade for Women, a ten-year effort to focus on women’s issues. From 1975 to 1985 international groups formed a series of conferences organized around the themes of equality, development, and peace. The conferences took place throughout the world and drew leaders and delegates from developing and industrialized nations alike. The Decade for Women culminated in the 1985 UN Nairobi Conference, held in Nairobi, Kenya, which was attended by 375 delegations of women from nations around the world.
 The United Nations’ Fourth World Conference on Women was held in Beijing, China, in 1995. Over 17,000 people registered for the event, including delegates from nearly 200 countries. The Platform for Action that emerged from the conference focused on the removal of obstacles to women’s equal participation in society. The most controversial sections of the platform concerned reproductive rights, particularly the right to have an abortion. The final document declared that “the ability of women to control their own fertility forms, an important basis for the enjoyment of other rights,” and asserted the right of women and men to have access to all legal methods of fertility regulation."
