Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the 'Net', in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links. It remains to be seen in which direction the Information Superhighway is headed, but many believe it is the educational hope of the future.
Internet computer connections are made by using telephone lines.

A few years ago, in one of the most fascinating and disturbing experiments in behavioural psychology, Stanley Milgram of Yale University tested 40 subjects from all walks of life for their willingness to obey instructions given by a 'leader' in a situation in which the subjects might feel a personal distaste for the actions they were called upon to perform. Specifically, Milgram told each volunteer 'teacher-subject' that the experiment was in the noble cause of education, and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils' ability to learn.
Several of the subjects were psychology students at Yale University.

In the mid-nineteenth century, the United States had tremendous natural resources that could be exploited in order to develop heavy industry. Most of the raw materials that are valuable in the manufacture of machinery, transportation facilities, and consumer goods lay ready to be worked into wealth. Iron, coal, and oil-the basic ingredients of industrial growth - were plentiful and needed only the application of technical expertise, organizational skill, and labor.
The word "ingredients" is closest in meaning to
A. products
B. minerals
C. methods
D. components

When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is becoming less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, even in remote jungles on the far side of the globe, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply over-sensitive to changes in the ecosystem? Could their rapid decline in numbers be signalling some coming environmental disaster for us all?
Biologists are unable to explain why frogs are dying.

A monarchy is a form of government where a single ruler is the head of state. It is one of the oldest forms of government in the world. Monarchs are usually kings or queens. But they can also be a chief, an emperor, or called by another name. In some countries, such as , the monarch is merely symbolic. They are figureheads with no real power. In other countries, the monarch wields considerable power. There are currently 29 sovereign monarchies around the world.
Hereditary monarchy is the most common style of succession. This form is used by most of the world's monarchies. In this case, all of the kings and queens come from the same family. A family that rules for a span of time is called a dynasty. The crown is passed down from one member to another member of the family. The hereditary system has the advantages of stability, continuity, and predictability. Family affection and loyalty are also stabilizing factors.
According to the passage, hereditary monarchy is
A. a form of absolute monarchy
B. a figurehead position
C. the most common style of succession
D. also called a tsar

Although the central region of Mexico's high plateau has been inhabited for at least 20,000 years, Mexico City only dates back to the 14th century. The Aztecs, or Mexica, had reached this area in the previous century, eventually settling on an island in Lake Texcoco. Here, in 1325, the city of Tenochtitlan began to take shape.
The lake was shallow, and during the nearly 200 years until 1519, the Aztecs expanded the inhabited area by land refill and the creation of artificial islands. Canals were dug for the transportation of goods and people. Aqueducts were constructed to bring drinking water from natural springs outside the city, dams to protect it against floods, and causeways and bridges to connect the city with the shore. There were many houses, palaces, temples, squares, markets and even a zoo. Perhaps the most striking construction of this period is the Templo Mayor, a double pyramid which still survives. As the capital of an empire stretching from Texas to Honduras, Tenochtitlan was a magnificent and important city. When the Spanish arrived, they called it the 'Venice of the New World'.
The area where people lived was artificially increased between 1325 and 1519.

The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920's and 1930's, nutrition became a science and the vitamin hunters replaced the microbe hunters.
In the 1940's and 1950's, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.
You are aware that the enzyme hunters have been replaced by a new breed of hunters who are tracking genes-the blueprints for each of the enzymes-and are discovering the defective genes that cause inherited diseases-diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and plants to create factories for the massive production of hormones and vaccines for medicine and for better crops for agriculture. Biotechnology has become a multibillion-dollar industry.
In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade of our waning century and in the early decades of the next? I wonder whether the hunters who will occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene hunters to the functions of the brain. What to call them? The head hunters. I will return to them later.
What is the main topic of the passage?
A. The progress of modern medical research
B. The discovery of enzymes
C. The potential of genetic engineering
D. The microbe hunters

In the 18th century, too, many new buildings were constructed. It was a prosperous period, when the new aristocracy paid for splendid buildings, banquets and balls, not to mention the latest fashions from Europe.
The rise of Napoleon in the early 19th century led to political changes throughout Europe. An uprising took place in Mexico in l810, with the aim of ending rule from Spain. This goal was finally achieved in 1821, when Mexico City briefly became the capital of the Mexican Empire. Since 1823, it has been the capital of the Republic of Mexico, apart from a short period, from 1863 to 1867, when the country was again an empire.
Spanish rule of Mexico ended in 1810.

People appear to be born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy — one plate, oneknife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that theyhave placed five knives, spoons, and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment.
Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped — or, as the case might be, bumped into — concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers — the idea of a oneness, a twoness, a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table — is itself far from innate.
With which of the following statements would the author be LEAST likely to agree?
A. Most people follow the same pattern of mathematical development.
B. Children naturally and easily learn mathematics.
C. Children learn to add before they
leam to subtract.
D. Mathematical development is subtle and gradual.
