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:
The brain of the average human weighs approximately 1.4 kilograms and consists of three main parts: the cerebrum, the cerebellum, and the brain stem. The cerebrum is by far the largest of the three parts, taking up 85% of the brain by weight. The outside layer of the cerebrum, the cerebral cortex, is a grooved and bumpy surface covering the nerve cells beneath. The various sections of the cerebrum are the sensory cortex, which is responsible for receiving and decoding sensory messages from throughout the body: the motor cortex, which sends action instructions to the skeletal muscles: and the association cortex, which receives, monitor and processes information. It is in the association cortex that the processes that allow humans to think take place. The cerebellum, located below the cerebrum in the back part of the skull, the section of the brain that controls balance and posture. The brain stem connects the cerebrum and the spinal cord. It control various body processes such as breathing and heartbeat.

The passage states that the most massive part of the brain is the________.

"The United Nations Environment Program (UNEP) encourages and coordinates sound environmental practices throughout the world. It grapples with ways to approach environmental problems on an international level, provides expertise to member countries, monitors environmental conditions worldwide, develops environmental standards, and recommends alternative energy sources.
 UNEP‘s work is guided by principles adopted at the 1992 UN Conference on Environment and Development, also known as the Earth Summit. The summit, which took place in Rio de Janeiro, Brazil, was the largest such conference ever held, attracting with more than 100 national leaders.
 The major theme of the 1992 Earth Summit was sustainable economic development, meaning development that does not use up or destroy so many of the world’s natural resources that it cannot be sustained over time. The meeting produced an overall plan, called Agenda 21, in which large developing countries promised to develop their Industries with an eye to protecting the environment. Industrialized countries pledged to help them do that. The Earth Summit also produced major treaties on biodiversity and global warming, although the latter treaty lacked enforcement provisions.
 In 2002, UNEP sponsored the World Summit on Sustainable Development in Johannesburg, South Africa. This conference sought to help developing countries, undergo industrialization without harming the environment. But progress on environmental issues is slow because proposed Solutions continue to pit the interests of poorer developing countries against those of richer industrialized nations. Most developing countries cannot afford to build an environmentally sound industrial base, while industrialized countries are unwilling to absorb the entire cost of environmental reform."

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.

Fermin _________.

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.

We should apologize _____________

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.

Which sentence is NOT TRUE?

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.

The writer learnt to sail ___________.

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.

   One day in 1924, five men who were camping in the Cascade Mountains of Washington saw a group of huge apelike creatures coming out of the woods. They hurried back to their cabin and locked themselves inside. While they were in, the creatures attacked them by throwing rocks against the walls of the cabin.

   After several hours, these strange hairy giants went back into the woods. After this incident the men returned to the town and told the people of their adventure. However, only a few people accepted their story. These were the people who remembered hearing tales about footprints of an animal that walked like a human being.

   The five men, however, were not the first people to have seen these creatures called Bigfoot. Long before their experience, local Native Americans were certain that a race of apelike animals had been living in the neighboring mountain for centuries. They called these creatures Sasquatch.

   In 1958, workmen, who were building a road through the jungles of Northern California often found huge footprints in the earth around their camp.

   Then in 1967, Roger Patterson, a man who was interested in finding Bigfoot went into the Northern California jungles with a friend. While riding, they were suddenly thrown off from their horses. Patterson saw a tall apelike animal standing not far away. He managed to shoot seven rolls of film of the hairy creature before the animal disappeared in the hushes. when Patterson's film was shown to the public, not many people believed his story.

   In another incident, Richard Brown, a music teacher and also an experienced hunter spotted a similar creature. He saw the animal clearly through the telescopic lens of his rifle. He said the creature looked more like a human than an animal.

   Later many other people also found deep footprints in the same area. In spite of regular reports of sightings and footprints, most experts still do not believe that Bigfoot really exists.

Did the town people believe the story of the five men about their meeting with Bigfoot?

   The American type of football was developed in the 19th century from soccer and rugby football. Played by professionals, amateurs, college and high school students, or young children, football in American is one of the most popular sports besides basketball and baseball. It attracts millions of fans each fall and people are very supportive of their favourite teams. The football playing field of today is rectangular in shape and measures 100 yards long and 53.5 yards wide. White lines are painted on the playing field to mark off the distances to the end zone. The games is divided into four quarters, each fifteen minutes long. The first two quarters are known as the first half. There is a rest period between two halves which usually last about fifteen minutes. Each team has eleven players. Each team has offensive players who play when the team has possession of the ball and defensive players who play when the other team has the possession of the ball. Because of the body contact players have during the game, helmets are worn to protect their head and face area, whereas pads are worn to protect the shoulders, arms, and legs. Also, there are officials carrying whistles and flags to make certain that the rules of the game are followed during the game. The football is made of leather and is brown in colour. It is shaped much like an oval and has white rings near each end of the football. These rings help the players see the ball when it is thrown or someone is running with it. The eight stitches on the top of the football help the players to grip the ball when throwing or passing. The most famous game of the year is Super Bowl that is played in January or February. It is televised around the world and is watched by millions of people each year.

What do officials do during the game of football?

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

UNICEF means? United Nations Children's Fund. It serves children in communities all the the world. It helps children of all races, nationalities, religions, and political systems in more than 140 developing countries. 
UNICEF, created in 1946 to help bring food and medicine to children who suffered during World War II in Europe. It began as a temporary agency, but became a permanent part of the United Nations in 1953 due to the need for its services around the world. UNICEF's primary concern is to help governments of developing countries improve the quality of life for almost one billion children. UNICEF's main office is in the United Nations offices in New York City, but it. also has more than 40 offices and 100 programs worldwide. In 1965, UNICEF won the Nobel Peace Prize for its work helping children and building brighter futures.
UNICEF works with governments to provide three kinds of services. First, UNICEF plans and develops programs in developing countries. These programs serve the community by providing health care, information about nutrition, basic education, and safe water and sanitation. Then UNICEF trains people to work in these programs. UNICEF also provides supplies and equipment that enable the programs to work. 
UNICEF's greatest concern is to improve the health of children. It does this in several ways. It improves water supplies in undeveloped countries where the water is not clean enough to drink. When children drink unclear water, they become very sick, and many die. UNICEF works hard to correct this. It also provides food and teaches people what to feed their children so they grow up to be healthy. UNICEF provides immunizations for children to prevent serious diseases. It gives important vitamins, such as vitamin A, to children who could go blind because of a lack of it . It also helps disabled children throughout the world. UNICEF helps train teachers and provides equipment and supplies for schools. By teaching people to read and write, UNICEF helps people to improve their lives.

In 1953 UNICEF became a permanent part of the United Nations because _______.

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 passage and choose the correct answer:

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.

 Boy’s education is promoted in the program of UNICEF

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.

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.

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.

According to the second paragraph, a useful theory is one that helps scientists to _______.
