Very few people, groups, or governments oppose globalization in its entirety. Instead, critics of globalization believe aspects of the way globalization operates should be changed. The debate over globalization is about what the best rules are for governing the global economy so that its advantages can grow while its problems can be solved.
On one side of this debate are those who stress the benefits of removing barriers to international trade and investment, allowing capital to be allocated more efficiently and giving consumers greater freedom of choice. With free-market globalization, investment funds can move unimpeded from the rich countries to the developing countries. Consumers can benefit from cheaper products because reduced taxes make goods produced at low cost from faraway places cheaper to buy. Producers of goods gain by selling to a wider market. More competition keeps sellers on their toes and allows ideas and new technology to spread and benefit others.
On the other side of the debate are critics who see neo-liberal policies as producing greater poverty, inequality, social conflict, cultural destruction, and environmental damage. They say that the most developed nations - the United States, Germany, and Japan - succeeded not because of free trade but because of protectionism and subsidies. They argue that the more recently successful economies of South Korea, Taiwan, and China all had strong state-led development strategies that did not follow neo-liberalism. These critics think that government encouragement of "infant industries"' that is, industries that are just beginning to develop - enables a country to become internationally competitive.
Furthermore, those who criticize the Washington Consensus suggest that the inflow and outflow of money from speculative investors must be limited to prevent bubbles. These bubbles are characterized by the rapid inflow of foreign funds that bid up domestic stock markets and property values. When the economy cannot sustain such expectations, the bubbles burst as investors panic and pull their money out of the country.
Protests by what is called the anti-globalization movement are seldom directed against globalization itself but rather against abuses that harm the rights of workers and the environment. The question raised by nongovernmental organizations and protesters at WTO and IMF gatherings is whether globalization will result in a rise of living standards or a race to the bottom as competition takes the form of lowering living standards and undermining environmental regulations.
One of the key problems of the 21st century will be determining to what extent markets should be regulated to promote fair competition, honest dealing, and fair distribution of public goods on a global scale.The author seems to be _________ globalization that helps promote economy and raise living standards globally.

Commuting is the practice of travelling a long distance to a town or city to work each day, and then travelling home again in the evening. The word commuting comes from commutation ticket, a US rail ticket for repeated journeys, called a season ticket in Britain. Regular travellers are called commuters.
The US has many commuters. A few, mostly on the East Coast commute by train or subway, but most depend on the car. Some leave home very early to avoid the traffic jams, and sleep in their cars until their office opens. Many people accept a long trip to work so that they can live in quiet "bedroom communities" away from the city, but another reason is 'white flight'. In the 1960s most cities began to desegregate their schools, so that there were no longer separate schools for white and black children. Many white families did not want to send their children to desegregated schools, so they moved to the suburbs, which have their own schools, and where, for various reasons, few black people live.
Millions of people in Britain commute by car or train. Some spend two or three hours a day travelling, so that they and their families can live in suburbia or in the countryside. Cities are surrounded by commuter belts. Part of the commuter belt around London is called the stock broker belt because it contains houses where rich business people live. Some places are becoming dormitory towns, because people sleep there but take little part in local activities.
Most commuters travel to and from work at the same time, causing the morning and evening rush hours, when buses and trains are crowded and there are traffic jams on the roads. Commuters on trains rarely talk to each other and spend their journey reading, sleeping or using their mobile phones, though this is not popular with other passengers. Increasing numbers of people now work at home some days of the week, linked to their offices by computer, a practice called telecommuting.
Cities in both Britain and the US are trying to reduce the number of cars conning into town each day. Some companies encourage car pooling (called car sharing in Britain), an arrangement for people who live and work near each other to travel together. Some Us cities have a public service that helps such people to contact each other, and traffic lanes are reserved for car-pool vehicles. But cars and petrol/gas are cheap in the US, and many people prefer to drive alone because it gives them more freedom. In Britain many cities have park-and-rids schemes, car parks on the edge of the city from which buses take drivers into the centre.The word 'repeated' in paragraph 1 most probably means .........................

Water scarcity is fast becoming one of the major limiting factors in world crop production. In many areas, poor agricultural practices have led to increasing desertification and the loss of formerly arable lands. Consequently, those plants species that are well adapted to survival in dry climates are being looked at for an answer in developing more efficient crops to grow on marginally arable lands.
Plants uses several mechanisms to ensure their survival in desert environments. Some involve purely mechanical and physical adaptations, such as the shape of the plant's surface, smaller leaf size, and extensive root systems. Some of the adaptations are related to chemical mechanisms. Many plants, such as cacti, have internal gums and mucilages which give them water-retaining properties. Another chemical mechanism is that of the epicuticular wax layer. This wax layer acts as an impervious cover to protect the plant. It prevents excessive loss of internal moisture. It also protects the plant from external aggression, which can come from inorganic agents such as gases, or organic agents which include bacteria ant plant pets.
Researchers have proposed that synthetic waxes with similar protective abilities could be prepared based on knowledge of desert plants. If successfully developed, such a compound could be used to greatly increase a plant's ability to maintain health in such adverse situations as inadequate water supply, limited fertilizers availability, attacked by pets, and poor storage after harvestingThe word "arable" is closest in meaning to..................

Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, contains a little more than two-thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is to eat substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having low cholesterol rates, and they can be scrambled or used in baking. One disadvantage, however, is that they are not good for frying, poaching, or boiling. A second alternative to regular eggs is a new type of egg, sometimes called 'designer' eggs. These eggs are produced by hens that are fed low-fat diets consisting of Ingredients such as canola oil, flax, and rice bran. In spite of their diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.
Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels have brought mixed results. It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body's production of blood cholesterol. Consequently, while it still makes sense to limit one's intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.What is the meaning of 'back up'?

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.
Traditional methods of teaching no longer suffice in this technological world. Currently there are more than 100,000 computers in schoolrooms in the United States. Students mediocre and bright alike, from the first stage through high school not only are not intimidated by my computers, but have become avid participants in the computer epoch.
Kids operating computer implement their curriculum with great versatility. A music student can program musical notes so that the computer will play Beethoven or the Beatles. For a biology class, the computer can produce a picture of the intricate envisage human biology in a profound way. A nuclear reactor is no longer an enigma to students who can see its workings in minute detail on a computer. In Wisconsi, the Chippewa Indians are studying their ancient and almost forgotten language with the aid of a computer. More commonly, the computer is used for drilling math and language concepts so that youngsters may learn at their own speed without trying the patience of their human teachers. The simplest computers aid the handicapped, who learn more rapidly from the computer than from humans. Once irksome, remedial drills and exercises now on computer are conducive to learning because the machine responds to correct answers with praise and to incorrect answers with frowns and even an occasional tear.
Adolescents have become so exhilarated by computers that they have developed their own jargon, easily understood by their peers but leaving their disconcerted parents in the dark. They have shown so much fervor for computer that they have formed computer clubs, beguile their leisure hours in computer stores, and even attend computer camps. A Boy Scout can get a computer merit badge. One ingenious young student devised a computer game for Atari will earn him $100,000 in royalties This is definitely the computer age. Manufacturers of computers are presently getting tax write – offs for donating equipment to colleges and universities and are pushing for legislation to obtain further deductions for contributions to elementary and high school. Furthermore, the price of computer for home or office is being sold for less than $100. At that price every class in the country will soon have computer kids.
When the author says parents are “left in the dark”, he means that they ____________

Higher education, also called tertiary, third stage or post secondary education, is the non-compulsory educational level following the completion of a school providing a secondary education, such as a high school, secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities are the main institutions that provide tertiary institutions. Tertiary education generally results in the receipt of certificates, diplomas, or academic degrees.
Higher education includes teaching, research and social services activities of universities, and within the realm of teaching, it includes both the undergraduate level and the graduate level. Higher education in that country generally involves work towards a degree-level or foundation degree qualification. It is therefore very important to national economies, both as a significant industry in its own right, and as a source of trained and educated personnel for the rest of the economy.
Where can we find tertiary education?

Learning means acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to manipulate toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to interact with their parents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for interacting with other children. After they finish school, people must learn to adapt to the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human- service workers need to understand how certain experiences change people's behaviors.
Employers, politicians, and advertisers make use of the principles of teaming to influence the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain.
Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later retrieves knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person's experiences.
There are many forms of learning, ranging from simple to complex. Simple forms of learning involve a single stimulus. A stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste. In a form of learning known as classical conditioning, people learn to associate two stimuli that occur in sequence, such as lightning followed by thunder. In operant conditioning, people learn by forming an association between a behavior and its consequences (reward or punishment). People and animals can also learn by observation - that is, by watching others perform behaviors. More complex forms of learning include learning languages, concepts, and motor skillsAccording to the passage, what are children NOT usually taught outside the classroom?

The idea of life in outer space has been talked about for a long time. Some scientists say that life development on Earth was far too unlikely for it to have happened anywhere else. Things had to be perfect for us to make it on this planet. Other scientists say that space is too big. Stars and other planets are far too numerous for there to be no other life in the universe.
For many years, there have been reports of visitors from other planets. People all around the world have claimed to see alien spaceships or even aliens themselves. There have been glimpses of these so-called UFOs (unidentified flying objects) flying through the air and they have even been captured on video. Some Americans believe that the U.S. Army found an alien spaceship crashed in the desert and then lied to the press about it. Although these sightings may be true, scientists have not found significant evidence that aliens exist.
If you go out into the countryside on a clear night and look up, you can see thousands of stars. Those stars make up a tiny part of our unniverse. There are more stars, planets, and galaxies than we can count. Even the smartest scientists can’t even come close to defining how big space is. The number of possible stars and planets out there is bigger than our ability to count. If we are really on the only planet that can sustain life, then we are very special in a universe full of amazing things.According to the passage, what is NOT true about the night sky?

Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pot dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.
Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.
All the major organs of the body show signs of aging. The brain, for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.
One of the most serious changes of old ago occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result In heart attack.
Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fibers can never be replaced once they wear out.
Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.All of the followings may be the outward signs of aging EXCEPT ................
