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. For many American university students, the weeklong spring break holiday means on endless party on a sunny beach in Florida or Mexico. In Panama City Beach in Florida, a city with permanent population of around 36.000, more than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the United States A weeklong drinking binge is not for everyone, however and a growing number of American university students have found a way to make spring break matter. For them, joining or leading a group of volunteers to travel locally or internationally and work to alleviate problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel good about. During one spring break students at James Madison University in Virginia participated in 15 alternative spring break" trips to nearby states, three others to more distant parts of the United States and five international trips. One group of JMU students travelled to Bogalusa, Louisiana to help rebuild homes damaged by Hurricane Katrina. Another group traveled to Mississippi to organize creative activities for children living in homeless shelter. One group of students did go to exhausting physical labor such Florida. but not to lie on the sand. They performed as maintaining hiker rails and destroying invasive plant species that threaten the native Florida ecosystem. Students who participate in alternative spring break projects find them very rewarding. While most university students have to get their degrees before they can start helping people, students volunteers are able to help people now. On the other hand, the accommodations are far from glamorous. Students often sleep on the floor of a school or church, or spend the week camping in tents. But students only pay around $250 for meals and transportation, which is much less than some their peers spend to travel to more traditional spring break hotspots Alternative spring break trips appear to be growing in popularity at universities across the United States. Students cite a number of reasons for participating. Some appreciate the opportunity to socialize and meet new friends. Others want to exercise their beliefs about peoples obligation to serve humanity and make the world a better place. Whatever their reasons, these students have discovered something that gives them rich rewards along with a break from school work. The word “binge” in the second paragraph probably means ___.

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. Living things include both the visible world of animals, plants, and fungi as well as the invisible world of bacteria and viruses. On a basic level, we can say that life is ordered. Organisms have an enormously complex organization. We're all familiar with the intricate systems of the basic unit of life, the cell. Life can also "work." Living creatures can take in energy from the environment. This energy, in the form of food, is transformed to maintain metabolic processes and for survival. Life grows and develops. This means more than just replicating or getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured. Life can reproduce. Think about the last time you accidentally stubbed your toe. Almost instantly, you moved back in pain. Finally, life can adapt and respond to the demands placed on it by the environment. There are three basic types of adaptations that can occur in higher organisms. Reversible changes occur as a response to changes in the environment. Let's say you live near sea level and you travel to a mountainous area. You may begin to experience difficulty breathing and an increase in heart rate as a result of the change in altitude. These symptoms go away when you go back down to sea level. Body-related changes occur as a result of prolonged changes in the environment. Using there previous example, if you were to stay in the mountainous area for a long time, you would notice that your heart rate would begin to slow down and you would begin to breath normally. These changes are also reversible. Genotypic changes (caused by genetic mutation) take place within the genetic makeup of the organism and are not reversible. An example would be the development of resistance to pesticides by insects and spiders. Which type of adaption is permanent?

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 from 38 to 45.    Halloween falls on October 31 each year in North America and other part of the world. What do you know about Halloween? Do you celebrate it in your country? Here is a little history about it?    Like other holidays, Halloween has evolved and changed throughout history. Over 2,000 years ago people called the Celts lived in what is now Ireland, the UK, and parts of Northern France. November 1 was their New Year's Day. They believed that the night before the New Year (October 31) was a time when the living and the dead came together.    More than a thousand years ago the Christian church named November 1 All Saints Day (also called All Hallows). This was a special holy day to honor the saints and other people who died for their religion. The night before All Hallows was called Hallows Eve. Later the name was changed to Halloween.    Like the Celts, the Europeans of that time also believed that the spirits of the dead would visit the earth on Halloween. They worried that evil spirits would cause problems or hurt them. So on that night people wore costumes that looked like ghosts or other evil creatures. They thought if they dressed like that, the spirits would think they were also dead and not harm them.    The tradition of Halloween was carried to America by the immigrating Europeans. Some of the traditions changed a little, though. For example, on Halloween in Europe some people would carry lanterns made from turnips. In America, pumpkins were more common. So people began putting candles inside them and using them as lanterns. That is why you see Jack 'o lanterns today.                             These days Halloween is not usually considered a religious holiday. It primarily a fun for children. Children dress up in costumes like people did a thousand years ago. But instead of worrying about evil spirits, they go from house to house. They knock on door and say "trick or treat". The owner of each house give candy or something special to each trick and treat. According to the passage, which of the following statements is NOT true?

That is why you see Jack 'o lanterns today.                             These days Halloween is not usually considered a religious holiday. It primarily a fun for children.

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 from 31 to 37.    A gesture is an action that sends a message from one person to another without using words. We use gestures to communicate with others. There are some gestures that have completely different meaning depending on when and where they are used.    When an American wants to show that something is OK. or good, he raises his hand and makes a circle with his thumb and foreigners. The circle sign has only one meaning for him. He might be surprised to learn that in other countries it can mean something different. In Japan, for instance, it is the gesture for money. In France, it means 'zero' or 'worthless'. Such differences can lead to all kinds of misunderstanding when foreigners meet. But why is it that the same gesture has so many different meanings?    When some people want to show that something is exact or precise, they make a sign to show that they are holding something between the tips of their thumb and forefinger. Many people from all over the world do this when they want to make a specific point as they are speaking. People later started using this signal to mean 'exactly right' or 'perfect'. This was how the famous OK was bom.    In Japan, money means coins and coins are around. Therefore, making a round hand sign came to represent money. It is simple as that. The French sign for 'nothing' or 'worthless' also has a simple origin. This time the circle doesn't represent a coin, but nought. Nought equals zero, zero equals nothing, nothing equals worthless. Which of the following can be inferred from the passage?
