If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand—the last thing you want to do is offend someone with any ignorant, boorish behavior. Here’s how to be polite in different countries.
When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.
In Mexico, when meeting others, women should initiate handshakes with men, but all people should avoid making too much eye contact; that can be seen as aggressive and belligerent behavior. If sharing a meal with others, keep your elbows off the table and try to avoid burping at all costs. Keep your hands off your hips, and make sure you never make the “okay” sign with your hand: it’s vulgar.
In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.
Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.

According to the passage, which of the following behavior should be avoided when sharing meals with others?

   Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator. To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.

   Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.

In terms of sheer size, the Antarctic Desert is the largest desert on Earth, measuring a total of 13.8 million square kilometers. Antarctica is the coldest, windiest, and most isolated continent on Earth, and is considered a desert because its annual precipitation can be less than 51 mm in the interior.
 It’s covered by a permanent ice sheet that contains 90% of the Earth’s fresh water. Only 2% of the continent isn’t covered by ice, and this land is strictly along the coasts, where all the life that is associated with the land mass (i.e. penguins, seals and various species of birds) reside. The other 98% of Antarctica is covered by ice which averages 1.6 km in thickness.
There are no permanent human residents, but anywhere from 1,000 to 5,000 researchers inhabit the research stations scattered across the continent – the largest being McMurdo Station, located on the tip of Ross Island. Beyond a limited range of mammals, only certain cold-adapted species of mites, algaes, and tundra vegetation can survive there.

Which species of animals can survive in Antarctic desert?

Although I left university with a good degree, I suddenly found that it was actually quite hard to find a job. After being unemployed for a few months, I realized I had to take the first thing that came along or I'd be in serious financial difficulties. And so, for six very long months, I became a market research telephone interviewer.

I knew it wasn't the best company in the world when they told me that I'd have to undergo three days of training before starting work, and that I wouldn't get paid for any of it. Still, I knew that the hourly rate when I actually did start full time would be a lot better than unemployment benefit, and I could work up to twelve hours a day, seven days a week if I wanted. So, I thought of the money I'd earn and put up with three days of unpaid training. Whatever those three days taught me - and I can't really remember anything about them today - I wasn't prepared for the way I would be treated by the supervisors.

It was worse than being at school. There were about twenty interviewers like myself, each sitting in a small, dark booth with an ancient computer and a dirty telephone. The booths were around the walls of the fifth floor of a concrete office block, and the supervisors sat in the middle of the room, listening in to all of our telephone interviews. We weren't allowed to talk to each other, and if we took more than about two seconds from ending one phone call and starting another, they would shout at us to hurry up and get on with our jobs. We even had to ask for permission to go to the toilet. I was amazed how slowly the day went. Our first break of the day came at eleven o'clock, two hours after we started. I'll always remember that feeling of despair when I would look at my watch thinking, 'It's must be nearly time for the break', only to find that it was quarter to ten and that there was another hour and a quarter to go. My next thought was always, 'I can't believe I'm going to be here until nine o'clock tonight.'

The most frightening aspect of the job was that I was actually quite good at it. 'Oh, no!' I thought.

‘Maybe I'm destined to be a market researcher for the rest of my life.' My boss certainly seemed to think so. One day - during a break, of course - she ordered me into her office. 'Simon,' she said, 'I'm promoting you. From tomorrow, you're off telecoms and onto credit card complaints. I'm sure you can handle it. There's no extra pay, but it is a very responsible position.'

Three weeks later, I quit. It was one of the best decisions I've ever made.

Most of us are interested in one kind of sport or another, even if we don't go in for it actively. Lots of people take up a particular sport at an early age, for example tennis, skiing, or ice-skating. If they get up to a suitably high standard, they may go in for local competitions or even championships. But special training is hard work and most young people don't keep it up. Many of them opt out when they come up against tough competition.

To become a professional in any sport, you have to go through with a strict training schedule. And it's not easy! It means doing without some of life's little pleasures, too. For example, to build up your physical strength you may have to stick to a special diet and give up some of your favorite foods. Smoking and alcohol are out, and to keep fit you have to work out regularly every day.

Sometimes it all pays off, but the road to success is long and there are no guarantees. No wonder that countless young talents decide to settle for a regular job instead, and, as far as professional sport is concerned, for looking on as spectators.

According to the passage, which of the following statements is TRUE about special training?

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:
    Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a byproduct of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.
    Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.
    Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America‟s number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.

The word it in the first paragraph refers to ___.

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

A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high temperatures cause rapid loss of water due to sweating and the absence of water sources with which to replenish it can result in dehydration and death within a few days. In addition, unprotected humans are also at risk from heatstroke.  Humans may also have to adapt to sandstorms in some deserts, not just in their adverse effects on respiratory systems and eyes, but also in their potentially harmful effects on equipment such as filters, vehicles, and communication equipment.  Sandstorms can last for hours, sometimes even days.  Despite this, some cultures have made hot deserts 'their home for thousands of years,  including the Bedouin, Tuareg tribe, and Pueblo people. Modern technology, including advanced irrigation systems, desalinization, and air conditioning, has made deserts much more hospitable, In the United States and Israel for example, desert farming has found extensive use.  In cold deserts, hypothermia and frostbite are the chief hazards, as well as dehydration in the absence of a source of heat to melt ice for drinking. Falling through pack-ice or surface ice layers into freezing water is a particular danger requiring emergency action to prevent rapid hypothermia Starvation is also a hazard; in low temperatures, the body requires much more food energy to maintain body heat and to move. As with hot deserts, some people such as the Inuit have adapted to the harsh conditions of cold deserts.

It is not easy to choose a career today. Hundreds of students are leaving schools and universities every year  to  seek  employment  in  the  various  professions,  though  employment  opportunities  are  not  increasing proportionately. As a result, there is a lot of unemployment.   

 The inability of the various professions to absorb all those seeking employment makes the choice of a career more difficult. Before one leaves school or university, one has many plans, confident that choosing a career will not be difficult. But when, the time comes to choose a career, one finds that there are others with better qualifications waiting to enter the same profession.  Disillusioned, one then looks for  any  kind of employment.  In this way,  many  who  wanted  to  become  police  inspectors or field  assistants  in  the  rubber estates in this country,  become  teachers  instead,  and many who  wanted  to  become  teachers,  have  become shop assistants. The lack of institutions where people could acquire the skills necessary for a particular career makes the choice of a career even more difficult. For example, if one desires to become a journalist, one has to receive some training and instruction in a school of journalism. But if there is no such school, one is compelled to think of some other career.

Before one leaves school or university, one ________. 

Read the passage and answer the question by circling the correct answer. 
Accustomed though we are to speaking of the films made before 1927 as "silent," the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Limeira films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film. As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before they were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry. To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as "pleasant," "sad," "lively." The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next. Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D.W. Griffith's film “Birth of a Nation”, which was released in 1915.

According to the passage, what kind of business was the Edison Company?
