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.

What makes it rain? Rain falls from clouds for the same reason anything falls to Earth. The Earth’s gravity pulls it. But every cloud is made of water droplets or ice crystals. Why doesn’t rain or snow fall constantly from all clouds? The droplets or ice crystals in clouds are exceedingly small. The effect of gravity on them is minute. Air currents move and lift droplets so that the net downward displacement is zero, even though the droplets are in constant motion.

Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft of sunlight. To the casual observer, dust seems to act in a totally random fashion moving about chaotically without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The cloud droplet of average size is only 1/2500 inch in diameter. It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it does not fall out of moving air at all. Only when the droplet grows to a diameter of 1/125 inch or larger can it fall from the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size large enough to fall out is the cause of rain and other forms of precipitation. This important growth process is called “coalescence”.

What is the diameter of the average cloud droplet?

A. 1/16 inch 

B. 1/125 inch

C. 1/2500 inch 

D. one millionth of an inch

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   22  to  26

A.   Read the passage carefully, then choose the correct answer.

The ruined temples of Angkor are perhaps one of the mast impressive Seven Wonders of the World. Located in modern day Cambodia near Lake TonIe Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire from the ninth to the fifteenth century. The ruins of Angkor are documented as same .of the mast impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.

One possible explanation far the downfall of the Khmer Empire has to do with the inhabitants' irrigation system. The temple and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding rice patties and farmland during the course of the year. Farmers were completely dependent upon the water for their crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.

Scientists speculate that toward the end of the Khmer Empire the hydraulic systems of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of the Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food quicker and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and the loss of water led to decrease in the food supply. With less food available, the people of Angkor slowly began to migrate to other parts of Cambodia thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.

22. What is the passage mainly about?

A. Modern day agricultural procedures in Cambodia.

B. A possible explanation for the, decline of a civilization.

C. The essential role water plays in farming.

D. Religious temples of the ancient Khmer Empire.

23. The passage preceding the passage most likely discusses ______.

A. architecture of ancient Asian civilization

B. religious practices of the people of Angkor

C. the form of government practiced by the Khmer Empire

D. the other six wonders of the world

24. According to the passage, Lake Tonle Sap in Cambodia ______.

A. is an enormous fresh body of water in Asia

B. was unable to supply enough fish for the people of Angkor

C. became polluted due to a population explosion

D. is one of the Seven Wonders of the World

25. Why does the author mention the hydraulic systems of the reservoirs?

A. They supplied irrigation from the Indian Ocean.

B. They became non-functional due to overuse.

C. They were destroyed by nearby warrior tribes.

D. They helped transport the sandstones for constructing temples.

26. It can be inferred from the passage that the inhabitants of the Khmer Empire ______.

A. were intentionally starved by the farmers

B. lost their food source due to excess rainfall

C. supplemented their diets with 'meat hunted in the nearby jungles

D. depended upon rice as their main source of food

27. All the following are mentioned as events that can affect food supply EXCEPT.

A. erosion of soil                                       B. contamination of soil

C. reduction of nutrients                            D. loss of water supply

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

          Think about your daily life. Do you follow the same road to work every day? Do you sit in the same place in the class? When you get dressed, do you always put the same leg or arm in first? You probably do, because we all have routines in our lives.

          Routines save time and energy because you do them without thinking, that’s why they are so important in the morning when your brain isn’t active. Here’s Jo talking about her morning routine.

  “Oh yes, I always do exactly the same things. I wake up at seven o’clock every morning, but I don’t get up till quarter past seven. I switch on the radio and listen to the news. Then I go to the loo and I brush my teeth. I have a shower and dry my hair. Then I choose my clothes and I get dressed, I don’t eat anything for breakfast. I just have a cup of coffee. Then I go to work. Yes, it’s always the same.”

          Routines are very useful, but they also make you uncreative. So sometimes it’s a good idea to break your routines. Get out of bed on the opposite side. Listen to a different radio station. Take a different route to work. Eat something different for breakfast. Change your routine. You never know, it could change your life.

Question 40. The word “loo” can best be replaced with _____________________.

      A. balcony                                  B. bedroom                   C. sink                   D.  toilet

Question 41. What is the main disadvantage of routines?

      A. Routines may change our life.

      B. Routines make us unable to create things or to have new ideas.

      C. Routines make a habit of never thinking before doing.

      D.  Routines make us do the same things day after day.

Question 42. Which of the sentences is true?

      A. Routines make our brain creative.                                  

      B. People who have routines are unable to think.

      C. We shouldn’t break our routines.    

      D.  Our lives could be changed if we change our routines.

 

Mark the letter A, B, C, or D on your answer sheet to show the underlined part that needs correction in each of the following questions.

Question 43. He plays sometimes (A) badminton or joins (B) a group of (C)workers to relax (D).
