Task 4. 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 16 – 20.              If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.             The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.              Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.            A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.             In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

Task 2. 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 6 – 10.A Working Vacation            Have you ever wondered what it would be like to get your dream job? It can take years to get the education and develop the skills you need for the perfect job. However, there is a way to experience your dream job without having to get the required training or degree. Since 2004, Brian Kurth’s company, Vocation Vacations, has been connecting people with mentors who have the jobs of their dreams.            Kurth had been working for a phone company before starting his own company. He didn’t like his job, and he had a long time to think about it on his drive to and from work. He also thought about his dream job while driving. He was interested in becoming a dog trainer, but he didn’t want to take any chances  and switch to a field he didn’t have experience in. He really wanted to know what the job was like and if  it was realistic for him to work towards his goal. So, he found a mentor – a dog trainer that could tell him about the job and everything it involved. After that, he helped his friends find mentors to explore jobs  they were interested in. They thought it was helpful to talk to people who had their dream jobs before spending lots of time and money getting the training they needed for those jobs.            Kurth saw how much this helped his friends, so he decided to turn it into his business. He started Vocation Vacations in 2004, and by 2005, the company was offering experience with over 200 dream jobs. Today, about 300 mentors work with the company to share their knowledge about their jobs. Customers pay to experience the job of their dreams and work with these mentors to see what a job is really like. A “job vacation” costs between 350 USD and 3,000 USD and can be for one to three days. Many people use Vocation Vacations to see if their dream job is a career path they want to continue. Others do  it just to experience the job of their dreams one time.          Vocation Vacations jobs are in the fields of fashion, food, entertainment, sports and animals. Many  people want to try glamorous jobs. For example, they want to try working as actors, music producers, photographers and fashion designers. According to Kurth, some other popular dream jobs are working as bakers, hotel managers and wedding planners.

Its ancient home was the forest, where it searched for different kinds of food, such as nuts, roots and dead animals, and found in the bushes (26)              for its almost hairless body from extremes of sun and cold. For many centuries the farmer allowed it to continue there, leaving his pigs to look after themselves most of the time. As the woodlands began to shrink, the pig slowly began to be kept on the farm itself. But it did not finally come into a shed, where it   was (27)               on waste food from the farm and the house, until the eighteenth  century.The pig, then, became a farm animal in  the (28)               of agricultural improvement in Britain in the eighteenth century, but it was given little attention by special animal breeders, for the major farmers of the time preferred to develop the larger kinds of animal.

Water (23)             from lakes and oceans and from the leaves of plants. From there it forms clouds which come back to earth (24)             rain, ice or snow. That water soaks into the ground or runs off. And the cycle continues with rivers running into the sea, plants transpiring and so on. Animals like us use it on the way through the cycle.For millions of years, changes in the water cycle were slow, but now, with the (25)             increase in the number of people on earth and the development of technology, we are having a dramatic impact on the way the water cycle behaves and on the quality of the water   itself.

VII. Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.            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 promotimg 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.
