For 70 years, UNICEF has been working on the ground in 190 countries and territories to promote children’s survival, protection and development. The world’s largest provider of vaccines for developing countries, UNICEF supports child health and nutrition, good water and sanitation, quality basic education for all boys and girls, and the protection of children from violence, exploitation, and AIDS. UNICEF is the driving force that helps build a world where the rights of every child are realized. As a global authority UNICEF is able to influence decision makers at the global level and turn the most innovative ideas into reality.

In all of its work, UNICEF takes a life-cycle based approach, recognizing the particular importance of early childhood development and adolescence. UNICEF programmes focus on the most disadvantaged children, including those living in fragile contexts, those with disabilities, those who are affected by rapid urbanization and those affected by environmental degradation.

UNICEF was created with a distinct purpose in mind: to work with others to overcome the obstacles that poverty, violence, disease and discrimination place in a child’s path. We advocate for measures to give children the best start in life, because proper care at the youngest age forms the strongest foundation for a person’s future.

We promote girls’ education – ensuring that they complete primary education as a minimum – because it benefits all children, both girls and boys. Girls who are educated grow up to become better thinkers, better citizens, and better parents to their own children. We act so that all children are immunized against common childhood diseases, and are well nourished: no child should suffer or die from a preventable illness. We work to prevent the spread of HIV/AIDS among young people because it is right to keep them from harm and enable them to protect others. We help children and families affected by HIV/AIDS to live their lives with dignity.

Southern Thailand was hit Thursday by the most severe haze from forest fires in Indonesia, forcing all schools in a province to close and disrupting flights in a popular tourist area, officially said.
The haze that has shrouded parts of Malaysia and Singapore for nearly two months reached hazardous levels in the southern Thai city of Songkhla, with the pollution index hitting a record-high reading of 365. A reading of 101-200 is unhealthy, 201-300 is very unhealthy and above 300 is hazardous.
“This is a crisis,” said Halem Jemarican, head of the Southern Environment Office. He said the pollution index in southern Thailand has never exceeded 300 before.
Halem said his office has worked with other authorities to have all schools in Songkhla province send students home and all outdoor sports stadiums to close temporarily. Warnings have been issued to vulnerable people such as children, the elderly and people with illnesses not to go out of their homes.
“The wind speed is very low this year in the south, causing haze to stay in our skies longer,” Halem said by telephone.
An airport official in Hat Yai, a popular tourist area, said three flights bound for Bangkok were delayed Thursday morning because of the haze. A flight from Bangkok to Hat Yai was diverted to Surat Thani on Wednesday evening. The official declined to be identified because of working rules.
Local media reported that cloud seeding has been discussed as a way to dispel the haze in southern Thailand, which is hundreds of kilometers (miles) from the forest fires in Indonesia's Sumatra island.
Southern Thailand boasts tropical beaches popular among tourists in Surat Thani and Phuket, two of the seven provinces suffering from the haze.

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 statement is true about life in the future?

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.

As can be inferred from the passage, sociologists can be frustrated when.......

What‌ ‌suggestion‌ ‌is‌ ‌TRUE‌ ‌according‌ ‌to‌ ‌the‌ ‌last‌ ‌paragraph?  ‌ ‌

When we moved to our new house near the sea, I was eight years old. Even before that I had spent every summer messing about on boats. My dad had taught me to sail before I learnt to ride a bike so I knew how I wanted to spend my time at the new house- I was going to get my own boat and sail it everyday. The house was only a few meters from the water's edge, and in rough weather the waves would come crashing into the front garden. I used to sit with my nose pressed to the glass, fascinated by the power of the ocean. I grew up watching the skies to see if it was going to rain; would I be going sailing that afternoon or not?
Of course I sometimes wished I could live in the town like my friends. I used to get angry with my parents, who had taken early retirement because they seemed incapable of getting anywhere on time. Dad drove me the eight miles to school everyday, but I was often late because he had been walking on the cliffs earlier in the morning and had lost track of time. When I was taking my university entrance exams, I used to stay over at a friend's in town, just in case. All in all, I was lucky to grow up by the sea and I still love to sail.

Growing up by the sea, the writer felt ___________.

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_______.

"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?

Choose the letter A, B, C or D to answer these following questions:
The World Trade Organization came into being in 1995. One of the youngest of the international organizations, the WTO is the successor to the General Agreement on Tariffs and Trade (GATT) established in the wake of the Second World War. So while the WTO is relatively young, the multilateral trading system that was originally set up under the GATT is over 70 years old. 
The past 70 years have seen an exceptional growth in world trade. Merchandise exports have grown on average by 6% annually. This growth in trade has been a powerful engine for overall economic expansion and on average trade has grown by 1.5 times more than the global economy each year. Total exports in 2016 were 250 times the level of 1948. The GATT and the WTO have helped to create a strong and prosperous trading system contributing to unprecedented growth.
The system was developed through a series of trade negotiations, or rounds, held under the GATT. The first rounds dealt mainly with tariff reductions but later negotiations included other areas such as anti-dumping and non-tariff measures. The 1986-94 round – the Uruguay Round – led to the WTO’s creation.

How many times were the total exports in 2016 in comparison with 1948?

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.

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

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!

The growing human population threatens wildlife because ___________.

For 70 years, UNICEF has been working on the ground in 190 countries and territories to promote children’s survival, protection and development. The world’s largest provider of vaccines for developing countries, UNICEF supports child health and nutrition, good water and sanitation, quality basic education for all boys and girls, and the protection of children from violence, exploitation, and AIDS. UNICEF is the driving force that helps build a world where the rights of every child are realized. As a global authority UNICEF is able to influence decision makers at the global level and turn the most innovative ideas into reality.

In all of its work, UNICEF takes a life-cycle based approach, recognizing the particular importance of early childhood development and adolescence. UNICEF programmes focus on the most disadvantaged children, including those living in fragile contexts, those with disabilities, those who are affected by rapid urbanization and those affected by environmental degradation.

UNICEF was created with a distinct purpose in mind: to work with others to overcome the obstacles that poverty, violence, disease and discrimination place in a child’s path. We advocate for measures to give children the best start in life, because proper care at the youngest age forms the strongest foundation for a person’s future.

We promote girls’ education – ensuring that they complete primary education as a minimum – because it benefits all children, both girls and boys. Girls who are educated grow up to become better thinkers, better citizens, and better parents to their own children. We act so that all children are immunized against common childhood diseases, and are well nourished: no child should suffer or die from a preventable illness. We work to prevent the spread of HIV/AIDS among young people because it is right to keep them from harm and enable them to protect others. We help children and families affected by HIV/AIDS to live their lives with dignity.
