AN UNWELCOME GUEST
Of the one in seven people in the UK who claim to have seen a ghost, the majority are women. This may be because women have far more association with the spirit world. Women trust their emotions and are generally better able than men to cope with the unexpected.
Housewife Fiona Blair describes herself as very practical and down-to-earth, and never believed in the idea that a house could be haunted. That all changed when she and her family moved into a manor house in the Midlands. Although the surveyor reckoned that the house required a lot of attention and was somewhat damp, they thought it was stunning. They could just afford it and it would be a good investment, so they took the plunge and decided to buy it.
Nonetheless, right from the start, Fiona had a strange sense that they were not alone in the house. One of her teenage daughters had left a towel over the back of a chair in the kitchen. Fiona was in the garden, and when she returned to the house, the towel was over the kitchen table like a tablecloth. On other occasions the family would find that objects such as glasses and vases had been turned upside-down.
This was only the start of the peculiar happenings. A particularly strange incident happened on Fiona's birthday. Fiona's husband, Mark, came home from work and went into the living room. He immediately came rushing out to ask who had bought her the beautiful flowers - but nobody had given Fiona flowers and her daughters had not put the flowers there. It remained a mystery how they had miraculously appeared.
Fiona was curious and decided to find out about the history of the house. What she discovered was rather alarming. Apparently a young girl, servant to a previous generation of owners, had been found dead in peculiar circumstances in the attic. Fiona and her family inevitably began to feel claustrophobic and trapped in the house, and eventually decided that they would have to move.
Unfortunately, things were not as simple as that. Each time they attempted to show the house to potential buyers, Fiona would of course ensure beforehand that everything was neat and tidy in order to make a good impression. But by the time anyone arrived, the entire house would be in a complete mess, and visitors complained of an unpleasant atmosphere. Eventually, after many months, an American couple viewed the house, and decided it had a certain attraction. For some reason, the ghost did not play its usual tricks, and Fiona was able to sell what had been her dream home.
Now living in a spacious modern apartment in London, Fiona wants to forget it all and move on with her life. 'At one point I thought I might be going out of my mind, it was all so frightening. We can almost laugh about it all now, but I hope we never experience anything like that again.

What did the ghost do when they decided to sell the house?

Choose the item among A, B, C or D that best answers the question about the passage:

"The United Nations (UN), international organization of countries created to promote world peace and cooperation. The UN was founded after World War II ended in 1945. Its mission is to maintain world peace, develop good relations between countries, promote cooperation in solving the world’s problems, and encourage respect for human rights.
 The UN is an organization of countries that agree to cooperate with one another. It brings together countries that are rich and poor, large and small, and have different social and political Systems. Member nations pledge to settle their disputes peacefully, to refrain from using force or the threat of force against other countries, and to refuse help to any country that opposes UN actions.
 UN membership is open to any country willing to further the UN mission and abide by its rules. Each country, no matter how large or small, has an equal voice and vote. Each country is also expected to pay dues to support the UN. As of 2004 the UN had 191 members, including nearly every country in the world.
 The UN’s influence in world affairs has fluctuated over the years, but the organization gained new prominence beginning in the 1990s. It was awarded the Nobel Peace Prize in 2001. Still, the UN faces constant challenges. It must continually secure the cooperation of its member nations because the organization has little independent power or authority. But getting that support is noi always easy. Many nations are reluctant to defer their own authority and follow the dictates of the UN."

4. Why does the UN face constant challenges?

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: 
A survey is a study generally in the form of an interview or a questionnaire that provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll As anyone who watches the news during campaigns presidential knows, these polls have become an important part of political life in the United States.
North Americans are familiar with the many "person on the street" interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such examples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the news people select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.
In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interview can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject's underlying feelings and reasons. However, questionnaires have the advantage of being cheaper and more consistent.

According to the passage, one disadvantage of person-on-the-street interviews is that they ________ .

If you are invited to someone’s house in America for dinner, you should bring a gift, such as a bunch of flowers or a box of chocolates. If you give your host a wrapped gift, he/she may open it in front of you. Opening a gift in front of the gift-giver in considered polite. It shows that the host is excited about receiving the gift and wants to show his/her appreciation to you immediately. Even if the host doesn’t like it, he/she will tell “a white lie” and say how much they like the gift to prevent the guest from feeling bad.
If your host asks you to arrive at the particular time, you should not arrive exactly on time or earlier than expected time, because this is considered to be inconvenient and therefore rude, as the host may not be ready.

Opening a gift in front of the gift-giver is considered __________

Milpa Alta is a region of twelve villages and towns to the south of Mexico City. In Milpa Alta, traditions are still very important and one of the most famous traditional events is a community meal. It takes place every Christmas and is called La Rejunta. More than a meal, it’s a feast, where about sixty thousand tamales and fifteen thousand litres of hot chocolate are made and consumed. Tamales are made from corn. They are typical of the region: the name Milpa Alta means ‘High cornfield’. The feast is offered to the people who go on the long walk to El Señor de Chalma about 80 kilometers away. It’s an important event on the religious calendar for local people and as many as 20,000 people take part. 
The planning and organisation of La Rejunta takes the whole year. Every year, different people are given the job of majordomo, which means they’re responsible for organising the meal. There’s a waiting list for the opportunity to do this and currently the next available year is 2046. This year’s majordomos are Virginia Meza Torres and her husband Fermín Lara Jiménez, who put their names on the list 14 years ago. 
One year before the meal, men go to the forest and collect wood that they store near the home of the majordomo. It has to be dry when it’s used to make the cooking fires. Local farmers grow most of the corn, meat and vegetables that are needed as ingredients. In the week before the feast, hundreds of volunteers arrive to help with the preparation and the cooking. No instant or ready-made foods are allowed. Amazingly, everyone seems to know what they have to do. On the day of the feast, the majordomos and others have stayed up all night cooking. Fermin is in charge of the numbers – making sure there are enough tamales for everyone. 
For the people of Milpa Alta, eating together is one of their most important traditions. One woman, Josefina García Jiménez, explains that sitting together at the table is like a glue that keeps people together. ‘It feels like I am passing down a tradition, and when they are adults, they will remember what I have done. Here we have time to cook, time to think about the ingredients, time to show our kids through cooking that we love them.’ The time that everybody stays at the table after the meal has finished is just as important as the food. 
They talk, tell stories and laugh together. At Christmas, La Rejunta is a giant version of a family meal.

According to the article, which statement is true?

Although people drive in all countries, the rules can be quite different between nations and areas. For this reason, you should always learn the laws before you decide to drive in a foreign country. If you are not careful, you can get into trouble since the rules might be very different from what you are used to. For example, you can find some big differences in laws related to the minimum driving age, the appropriate side of the road to drive on, and mobile phone use while driving.

In the U.S., people who live in Alaska may obtain a learner’s permit (legal permission to drive while being supervised) at the age of fourteen. This is quite different from the driving laws of Niger, where a person must be at least twenty-three years old to drive. If you are inquisitive to know the minimum driving age in most countries, the answer is eighteen. It may also surprise you to learn that not every country allows its citizens to drive, although most of them do. For example, women are not allowed to drive in Saudi Arabia no matter how old they are. Instead, they must have a male family member or hired male driver to travel by car.

Driving on the right or left side of the road also varies. For instance, in Great Britain, Cyprus, Australia, India, and Malaysia people drive on the left. However, in the U.S., Mexico, France, and Canada people are required to drive on the right. As a matter of fact, one country can have different driving rules for different areas. People in Hong Kong drive on the left, while drivers in other parts of China use the right side of the road.

Other driving laws that are different between countries include those related to using mobile phones. In Japan, using any kind of mobile phone device is illegal, even if you do not need to hold the phone with your hands. However, in Argentina and Australia, drivers are allowed to talk on their mobile phones as long as they do not use their hands. 

You might also find it interesting to learn that some countries have very unusual laws. For example, in the country of Cyprus, it is against the law to eat or drink anything while driving. Even more interesting is that in Germany, there is a famous road called the Autobahn, where certain parts have no speed limit at all!

Which of the following is TRUE according to the passage?

There is a strange paradox to the success of the Asian education model. On the one hand, class sizes are huge by Western standards with between 30 and 40 students per class, in countries like Japan and Korea. On the other hand, school children in developed Asian economies rank among the highest in the world for academic achievement in the areas of science and mathematics, especially on standardised tests. Meanwhile, British secondary school students fail to shine in conditions most educational researchers would say are far more likely to help them succeed.

Classroom management seems to be easier in places like Korea, and perhaps lessons are more effective as a direct consequence. After all, we are only too aware of the decline in discipline standards in our own school: belligerent and disrespectful students appear to be the norm these days. Teachers in Britain seem powerless to control what happens anymore. Surely this situation cannot create a very effective learning environment, so perhaps the number of students is far less relevant than is the manner in which they conduct themselves.

But there are other factors to consider, too. There is the home environment. The traditional family unit still remains relatively intact in Korea. Few children come from broken homes, so there is a sense of security, safety and trust both at home and at school. In Britain meanwhile, one in every two marriages fails and divorce rates are sky high. Perhaps children struggle to cope with unstable family conditions and their only way to express their frustration is by misbehaving at school.

But while the Japanese, Korean and Asian models generally do seem to produce excellent results, the statistics don’t tell the whole truth. You see, behind those great maths and science scores, there is a quite remarkable work ethic. Asian students tend to put their education before literally everything else. They do very few extracurricular activities and devote far more time to their studies than their British peers.

There has been a lot of attention and praise given to these Asian models and their “impressive” statistics of late. And without question, some of this praise is justified, but it seems to be a case of two extremes in operation here. At one end, there is the discipline and unbelievably hard work ethic of the Asian students – success in education before all else. At the other end, British students at times appear careless and extremely undisciplined by comparison, but at least they Do have the free time to enjoy their youth and explore their interests. Is either system better outright? Or is it perhaps about time we stopped comparing and started trying to combine the best bits of both, so that we can finally offer our students a balanced, worthwhile education

The word “They” in paragraph 4 refers to_______.

People used to know more or less how their children would live. Now things are changing so quickly that they don’t even know what their own lives will be like in a few years’ time. What follows is not science fiction. It is how experts see the future. You are daydreaming behind the steering wheel; is it too dangerous? No! That’s no problem because you have it on automatic pilot, and with its hi – tech computers and cameras, your car “know” how to get you home safe and sound. What is for lunch? In the old days you used to stop off to buy a hamburger or a pizza. Now you use your diagnostic machine to find out which foods your body needs. If your body needs more vegetables and less fat, your food – preparation machine makes you a salad.
 After lunch, you go down the hall to your home office. Here you have everything you need to do your work. Thanks to your information screen and your latest generation computer, you needn’t go to the office anymore. The information screen shows an urgent message from a co-worker in Brazil. You can instantly send back a reply to him and go on to deal with other matters.

Which of the following is NOT true about life in the future?

The past fifty years or so have seen the gradual disappearance of animals from this earth, fishes from the sea, trees and plants from the land.
Many factors result in this unpleasant phenomenon. Among them, hunting is the main factor that endangers wildlife. Some people kill wildlife for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales.

Apart from this, the rapidly growing human population threatens wildlife on land, too. Towns expand and roads have to be built, so forests are burnt and trees are chopped down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wildlife. Tigers, lions and leopards slowly die off without the food and shelter that the forests provide.

In addition, rapid urbanization means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened.

Many depend greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot do without wildlife; or he himself would become extinct. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wildlife to continue living rather than to move all signs of it.
 
Man must learn to farm the sea as he does the land. He should regulate the amount of frequency of his catch. He should allow fish to breed and multiply before netting them. A man also needs to build forest reserves, and to pass a law prohibiting the killing of animals, especially those that already rare. To retain the present animal kingdom, the least that man can do is to clean the seas and rivers to prevent pollution. The cycle of nature is such that it forms a vicious circle. The insecticides and pesticides that we spray on crops can kill the birds and animals that feed on them. When a man eats these poisoned animals, he himself can die. We must therefore test the chemicals to be used before they are sprayed or it might mean the death of man!

   Although speech is the most advanced form of communication, there are many ways of communicating without using speech. Signals, signs, symbols, and gestures may be found in every known culture. The basic function of signal is to impinge upon the environment in such a way that it attracts attention, as, for example, the dots and dashes of a telegraph circuit. Coded to refer to speech, the potential for communication is very great. Less adaptable to the codification of words, signs also contain meaning in and of themselves. A stop sign or a barber pole conveys meaning quickly and conveniently.

   Symbols are more difficult to describe than either signals or signs because of their intricate relationship with the receiver’s cultural perceptions. In some cultures, applauding in a theater provides performers with an auditory symbol of approval. Gestures such as waving and handshaking also communicate certain cultural messages.

   Although signals, signs, symbols, and gestures are very useful, they do have a major disadvantage in communication. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. Without an exchange of ideas, interaction comes to a halt. As a result, means of communication intended to be used for long distances and extended periods must be based upon speech. To radio, television, and the telephone, one must add fax, paging systems, electronic mail, and the Internet, and no one doubts but that there are more means of communication on the horizon.

It may be concluded from this passage that ____________.

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.

   Smallpox was the first widespread disease to be eliminated by human intervention. Known as a highly contagious viral disease, it broke out in Europe, causing the deaths of millions of people until the vaccination was invented by Edward Jenner around 1800. In many nations, it was a terror, a fatal disease until very recently. Its victims suffer high fever, vomiting and painful, itchy, pustules that left scars. In villages and cities all over the world, people were worried about suffering smallpox.In May, 1966, the World Health Organization (WHO), an agency of the United Nations was authorized to initiate a global campaign to eradicate smallpox. The goal was to eliminate the disease in one decade. At the time, the disease posed a serious threat to people in more than thirty nations. Because similar projects for malaria and yellow fever had failed, few believed that smallpox could actually be eradicated but eleven years after the initial organization of the campaign, no cases were reported in the field.The strategy was not only to provide mass vaccinations but also to isolate patients with active smallpox in order to contain the spread of the disease and to break the chain of human transmission. Rewards for reporting smallpox assisted in motivating the public to aid health workers. One by one, each small-pox victim was sought out, removed from contact with others and treated. At the same time, the entire village where the victim had lived was vaccinated.By April of 1978 WHO officials announced that they had isolated the last known case of the disease but health workers continued to search for new cases for additional years to be completely sure. In May, 1980, a formal statement was made to the global community. Today smallpox is no longer a threat to humanity. Routine vaccinations have been stopped worldwide.

According to the passage, what way was used to eliminate the spread of smallpox?

It is difficult to write rules that tell exactly when we should apologize, but it is not difficult to learn how. If we have done something to hurt someone’s feeling or if we have been impolite or rude, we should apologize. An apology indicates that we realize we have made a mistake, and we are sorry for it. It is a way of expressing our regret for something. When we apologize, we admit our wrongdoing, usually offer a reason for it, and express regret.
The simplest way to apologize is to say “I’m sorry”, but often that is not enough. Let’s take a common situation. Mario is late for class and enters the classroom, interrupting the teacher in the middle of the class. What does he do? The most polite action is usually to take a seat as quietly as possible and apologize later. But if the teacher stops and waits for him to say something, he could apologize simply “I’m sorry I’m late”, ask permission to take his seat, and sit down. Naturally, more than this, a reason for the tardiness, is needed, but this is not the time or the place for it because he has already caused one interruption and doesn’t need to make it any longer or worse than it already is.

It is ________ to write the rules that tell exactly when we should apologize.

The Census Counts!
Every ten years there is a national census to count the number of people. The census counts the number of people in each area, the number of men and women, their ages, their profession, their family size and status. The census is the only way to count everyone. Its results are used by a great many people and are available to everyone. The census is useful; it helps to work out present and future needs for housing by seeing how many people are housed now, or the sizes and ages of their families. In addition, the size of annual grants made by the Government to public services depends largely on the numbers and needs of people in the area provided by the census. Furthermore, the census shows how many people have moved from one area to another and how the number of the local work force is changing.
The census is taken in order to provide the figures about the nation as a whole. It does not give information about any named person, family or household. Therefore, names and addresses are needed on the forms but they are not fed into the computer. After the census, the forms with the names on are locked away and will not be released to anyone outside the Census Office for 100 years. The answers people give on their census forms will be treated in strict confidence. Everyone working on the census is sworn to secrecy and can be sued if he or she improperly reveals information.

What is the main idea of the passage? 

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.

   In Science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

   After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

   Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves arc not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house."

   Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hypothesis is a leap into the unknown. It extends the scientist's thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.
