Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate thecorrect answer to each of the questions.
Instructors at American colleges and universities use many different teaching methods. Some instructors give assignments everyday. They grade homework. Students in their classes have to take many quizzes, a midterm exam, and a final test. Other instructors give only writing assignments. Some teachers always follow a course outline and usually use the text book. Others send students to the library for assignments.
The atmosphere in some classrooms is very formal. Students call their instructors “Professor Smith,” “Mrs Jones,” and so on. Some teachers wear business clothes and give lectures. Other classrooms have an informal atmosphere. Students and teachers discuss their ideas. Instructors dress informally, and students call them by their first names. American teachers are not alike in their teaching styles.
At most American colleges and universities, facilities for learning and recreation are available to students. Students can often use type-writers, tape recorders, video machines, and computers at libraries and learning centres. They can buy books, notebooks, and other things at campus stores. They can get advice on their problems from counselors and individual help with their classes from tutors. Students can relax and have fun on campus, too. Some schools have swimming pools and tennis courts. Most have snack bars and cafeterias.

Choose the word or phrase among A, B, C or D that best fits the blank space in the following passage.

No matter who we are or where we are from, we only have 24 hours each day to get things done. Some people seem to make the most (1) ____ their time, using it to achieve their goals and dreams. Others feel that life is passing them by and they aren't (2) ____ anything. If you are in the latter group, it is not too late to turn things around. By implementing a few simple hacks, you can start getting better results very quickly.

If you want to become more productive, it pays to learn about the Pareto (3) ____ (which is also known as the 80-20 rule). It states that for most tasks, 80 percent of the results we get come from 20 percent of the work we do. For example, 80 percent of the company sales usually come from 20 percent of customers. Therefore, the trick is to focus your (4) ____ on the key 20 percent of actions that truly matter to greatly improve your results.

In some cases, people may be busy from morning to night but still seem to get nothing done. In this (5) ____, the problem might be that clear goals haven't been set. To fix this, set some time aside to list the things you want to achieve in life. Then, select the top three or four that you want to focus on for the next year. Look at your goals every night before bedtime and ask yourself what are the next (6) ____ to accomplish each day. Then, promise yourself that you will finish these tasks no matter how busy you get. If possible try completing the tasks first thing in the morning so you are (7) ____ of success.

Another common mistake regarding productivity is not considering our (8) ____ levels. If we try to work around the clock, we will eventually get tired and quit. Everyone needs time to sleep, eat, (9) ____ with friends, and unwind from the stress of the day. To make sure you don't burn out, be sure to schedule some time for breaks and fun activities into your (10) ____ every day. Finally, no matter how difficult your goals may seem, remember the old saying that "a journey of a thousand miles begins with a single step".

Curious about which digital camera is best for you? Where you can hear reggae music in  Toronto? Or what the distance is to Mars? Question-and-answer sites offer an alternative to the  ubiquitous search engine: a place to post a question – and then wait for another Internet user to  respond. 
The idea isn’t new: Usenet newsgroups have let us do this for years. But Q&A sites offer features that enhance and simplify the process. All offer eBay-like feedback, where users rate the  helpfulness of experts: over time, these scores become a benchmark score for determining how  trustworthy someone’s answers are. Question-and-answer sites also e-mail you when an expert has responded, and they offer personalized page where you can see the questions you’ve asked, the  people who have responded, and what they’ve had to say.

Archaeological records ― paintings, drawings, and carvings of humans engaged in activities involving the use of hands ― indicate that humans have been predominantly right-handed for more than 5,000 years. In ancient Egyptian artwork, for example, the right-hand is depicted as the dominant one in about 90percent of the examples. Fracture or wear patterns on tools also indicate that a majority of ancient people were right-handed. Cro-Magnon cave paintings some 2,000 years old commonly show outlines of human hands made by placing one hand against the cave wall and applying paint with the other. Children today make similar outlines of their hands with crayons on paper. With few exceptions, left hands of Cro-Magnons are displayed on cave walls, indicating that the paintings were usually done by right- handers. Anthropological evidence pushes the record of handedness in early human ancestors back to at least 1.4 million years ago. One important line of evidence comes from flaking patterns of stone cores used in toolmaking: implements flaked with a clockwise motion (indicating a right-handed toolmaker) can be distinguished from those flaked with a counter-clockwise rotation (indicating a left-handed toolmaker). Even scratches found on fossil human teeth offer clues. Ancient humans are thought to have cut meat into strips by holding it between their teeth and slicing it with stone knives, as do the present-day Inuit. Occasionally the knives slip and leave scratches on the users' teeth. Scratches made with a left-to-right stroke direction (by right-handers) are more common than scratches in the opposite direction (made by left-handers). Still other evidence comes from cranial morphology: scientists think that physical differences between the right and left sides of the interior of the skull indicate subtle physical differences between the two sides of the brain. The variation between the hemispheres corresponds to which side of the body is used to perform specific activities. Such studies, as well as studies of tool use, indicate that right- or leftsided dominance is not exclusive to modern Homo sapiens. Populations of Neanderthals, such as Homo erectus and Homo habilis, seem to have been predominantly right-handed, as we are.

In the future, maybe all cars that run on petrol will be replaced by solar cars, which have been around for a while, but with recent developments in solar car design and the measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car is more reality than fantasy. A solar car is a vehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) into electrical energy. As a source of energy on earth, there is nothing like the sun: in a mere one thousandth of one second (.001) , the sun emits enough energy to fulfill our planet's energy needs for the next 5,000 years. It is a staggering fact, and an exciting one. Since the energy from the sun is responsible for renewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for not only cars, but for the entire energy crisis. Despite the appearance that solar energy may be the least, feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically solar powered cars are beginning to be developed. How do Solar Cars work?

The photovoltaic cells absorb photons from sunlight. This action generates heat, which the cells then convert into electrical energy and stores in an onboard battery. This process of conversion is called the photovoltaic effect. Not surprisingly, such a vehicle has zero emissions, and is very environmentally friendly. Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progresses the efficiency of these cells will grow. This will make solar energy and solar cars the fuel and car of the future - a closer reality.

My city has been changing since the municipal authority had a plan to renovate the canal systems. The project cost a huge amount of money which was from the support of the world bank and the city’s budget. Before the renovation, the canal was the dirtiest place full of rubbish along its sides. Many ramshackle shacks were built to be shelters of the impoverished working families migrating to this city to earn their living. Household wastes were directly dumped into the canal, resulting in the very contaminated environment. It was said that the very unpleasant smell releasing from the canal was unable to be eliminated, and the living condition there would not be better. However, thanks to the advanced technology and methods as well as the city authority’s effort, everything has been changing. There is no longer the disgusting smell or shabby houses along both sides of the canal. Instead, the road running parallel to the canal is now full of shade of greenery and the water now is so clean that it is a friendly habitat for a variety of fish. The residents now can walk or do morning exercise on the sidewalks along the banks to enjoy the fresh atmosphere. Former inhabitants are also relocated in new apartments with much better living conditions than before. The canal creates not only a beautiful urban landscape, but also brings a lot of economic benefits to local dwellers. Because of its reformation, the city is changing fast too.

One of the most interesting authors of the twentieth century, J.R.R Tolkien, achieved fame through his highly inventive trilogy. The Lord of the Rings. Born in 1892, Tolkien received his education from Oxford and then served in World War I. After the war, he became a professor of Anglo -Saxon and English language and literature at Oxford University.
Although published in 1965, the three books that comprise the Lord of the Rings were written in intervals from 1936 to 1949. This was mainly due to Tolkien's responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien.
The trilogy is remarkable not only for its highly developed account of historical fiction but also its success as a modern heroic epic. The main plot describes the struggle between good and evil kingdom as they try to acquire a magic ring that has the power to rule the world. The novels, which are set in a time called Middle Earth, describe a detailed fantasy world. Established before humans populated the Earth, Middle Earth was inhabited by good and evil creatures such as hobbits, elves, monsters, wizards, and some humans. The characters and the setting of Middle Earth were modeled after mythological stories from Greece and Northern Europe.
Although readers have scrutinized the texts for inner meaning and have tried to connect the trilogy with Tolkien's real life experiences in England during World War II, he denied the connection. He claims that the story began in his years as an undergraduate student and grew out of his desire to create mythology and legends about elves and their language.
Tolkien was a masterful fantasy novelist who used his extensive knowledge of folklore to create a body of work that is still read and enjoyed throughout the world today.

"Until recently, the ‘Science of the future’ was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next breakthrough in technology will be brought about through a combination of those
two Sciences with organic chemistry and genetic engineering. This Science is the combination of biotechnology.
 Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness, and flexibility that we find in the bodies of ordinary insects.
 Nevertheless, scientists in the laboratory have already succeeded in ‘growing’ a material that has many of the characteristics of human skin. The next step may well be ‘biotech heart and eyes’ which can replace diseased organs in human beings. This will not be rejected by the body, as in the case with organs from humans.
 The application of biotechnology to energy production seems even more promising. In 1996, the famous science-fiction writer Arthur c. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner."

INTERNET JOBS

Contrary to popular belief, one does not have to be a trained programmer to work online.

Of course, there are plenty of jobs available for people with high-tech computer skills, but the growth of new media has opened up a wide range of Internet career opportunities requiring only a minimal level of technical expertise. Probably one of the most well-known online job opportunities is the job of Webmaster. However, it is hard to define one basic job description for this position. The qualifications and responsibilities depend on what tasks a particular organization needs a Webmaster to perform.

To specify the job description of a Webmaster, one needs to identify the hardware and software the website the Webmaster will manage is running on. Different types of hardware and software require different skill sets to manage them. Another key factor is whether the website will be running internally or externally (renting shared space on the company servers). Finally, the responsibilities of a webmaster also depend on whether he or she will be working independently, or whether the firm will provide people to help. All of these factors need to be considered before one can create an accurate webmaster job description.

Webmaster is one type of Internet career requiring in-depth knowledge of the latest computer applications. However, there are also online jobs available for which traditional skills remain in high demand. Content jobs require excellent writing skills and a good sense of the web as a "new media'.

The term "new media" is difficult to define because it compasses a constantly growing set of new technologies and skills. Specifically, it includes websites, email internet technology, CD- ROM, DVD, streaming audio and video, interactive multimedia presentations, e-books, digital music, computer illustration, video games, virtual reality, and computer artistry.

Additionally, many of today's Internet careers are becoming paid-by-the-job professions. With many companies having to downsize in tough economic items, the outsourcing and contracting of freelance workers online has become common business practice. The Internet provides an infinite pool of buyers from around the world with whom freelancers can contract their services. An added benefit to such their own country. online jobs is that freelancers are able to work on projects with companies outside

How much can a person make in these kinds of careers? As with many questions related to today's evolving technology, there is no simple answer. There are many companies willing to pay people with Internet skills salaries well over 70,000 a year. Generally, web masters start at about 70,000 30,000 per year, but salaries can vary greatly. Freelance writers working online have been known to make between 40,000 to 70,000 a year.
