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

Although they are an inexpensive supplier of vitamins, minerals and high- quality protein, eggs, also contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, contains a little more than two- thirds of the suggested cholesterol limit. This knowledge has driven egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is eating substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having low cholesterol rates, and they can be scrambled or used in baking. One disadvantage, however, is that they are not good for frying, poaching or boiling. A second alternative to regular eggs is a new type of egg, sometimes called “designer” eggs. These eggs are produced by hens that are fed low- fat diets consisting of ingredients such as canola oil, flax and rice bran. In spite of their diet, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.

Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their claim. And, in fact, studies on relationship between eggs and human cholesterol levels have brought mixed result. It may be that it is not the type of eggs that is the main determinant of cholesterol but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body’s production of blood cholesterol. Consequently, while it still makes sense to limit one’s intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.

 

What is the main purpose of the passage?

A. To introduce the idea that dietary at increases the blood cholesterol level

B. To make people know about the relationship between eggs and cholesterol

C. To persuade people that eggs are unhealthy and should not be eaten

D. To convince people to eat “designer” eggs and eggs substitutes

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

Choosing a career may be one of the hardest jobs you ever have, and it must be done with care. View a career as an opportunity to do something you love, not simply as a way to earn a living. Investing the time and effort to thoroughly explore your options can mean the difference between finding a stimulating and rewarding career and move from job to unsatisfying job in an attempt to find the right one. Work influences virtually every aspect of your life, from your choice of friends to where you live. Here are just a few of the factors to consider.

Deciding what matters most to you is essential to making the right decision. You may want to begin by assessing your likes, dislikes, strengths and weaknesses. Think about the classes, hobbies and surroundings that you find most appealing. Ask yourself questions, such as “Would you like to travel? Do you want to work with children? Are you more suited to solitary or cooperative work?” There are no right or wrong answers; only you know what is important to you. Determine which job features you require, which ones you would prefer, and which ones you cannot accept. Then rank them in order of importance to you.

The setting of the job is one factor to take into account. You may not want to sit at a desk all day. If not, there is diversity of occupation – building inspector, supervisor, and real esate agent – that involve a great deal of time away from the office. Geographical location may be a concern, and employment in some fields is concentrated in certain regions. Advertising job can generally be found only in large cities. On the other hand, many industries such as hostels, law education, and retail sales are found in all regions of the country. If a high salary is important to you, do not judge a career by its starting wages. Many jobs, such as insurance sales, offer relatively low starting salaries; however, pay substantially increases along with your experience, additional training, promotions and commission.

Don’t rule out any occupation without learning more about it. Some industries evoke positive or negative associations. The travelling life of a flight attendant appears glamorous, while that of a plumber does not. Remember that many jobs are not what they appear to be at first, and may have merits or demerits that are less obvious. Flight attendants must work long, grueling hours without sleeps, whereas plumbers can be as highly paid as doctors.

Another point to consider is that as you mature, you will likely develop new interests and skills that may point the way to new opportunities. The choices you make today need not be your final one.

 

Why does the author mention “long, grueling hours without sleeps” in paragraph 4?

A. To emphasize the difficulty of working as a plumber

B. To contrast the reality of a flight attendant’s job with most people’s perception

C. To show that people must work hard for the career as a flight attendant

D. To discourage readers from choosing a career as a flight attendant

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 and plants 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. Life can also “work”. Living creatures can take in energy from the environment. This energy, in the form of food, is changed to maintain metabolic processes and for survival. Life grows and develops. This means more than just getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured.  Life can reproduce. Life can only come from other living creatures. Life can respond.  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 height. These signs of sickness go away when you go back down to sea level.

          Body- related changes happen as a result of prolonged changes in the environment. Using the 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 change) take place within the genetic make up of the organism and are not reversible. An example would be the development of resistance to bug-killing chemicals by insects and spiders.

Question:Which of the followings is NOT a feature of life?

A. Getting a job.

B.  Giving birth.

C.  Getting larger and self-repairing.

D.  Reacting to the environment.

Read the following passage on commuting, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 51 to 60.

Many folk cures which have been around for centuries may be more therapeutic than previously suspected. A case in point is that of penicillin Alexander Fleming did not just randomly choose cheese molds to study when he discovered this very important bacteria-killing substance. Moldy cheese was frequently given to patients as a remedy for illness at one time Fleming just isolated what it was about the cheese which cured the patients.

In parts of South America, a powder obtained from grinding sugar cane is used for healing infections in wounds and ulcers. This usage may date back to pre-Colombian times. Experiments carried out on several hundred patients indicate that ordinary sugar in high concentrations is lethal to bacteria. Its suction effect eliminates dead cells and it generates a glasslike layer which protects the wound and ensures healing.

Another example of folk medicine which scientists are investigating is that of Arab fishermen who rub their wounds with a venomous catfish to quicken healing. This catfish excretes a gellike slime which scientist found to contain antibiotics coagulant that helps close injured blood vessels, anti-inflammatory agents, and a chemical that directs production of a glue-like material that aids healing.

It is hoped that by documenting these folk remedies and experimenting to see if results are indeed beneficial, an analysis of the substance be made, and synthetic substances be developed for human consumption.

In what way are cheese molds, sugar, and catfish slime similar? 

A. They eliminate dead cells

B. They heal wounds 

C. They fight bacteria

D. They cause blood clots

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 following questions from 1 to 8.

Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film.

As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before the y were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry.

To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications

of mood as “pleasant’, “sad”, “lively”. The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next.

Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D. w. Griffith’s film Birth of a Nation, which was released in 1915.

The word “scores” most likely mean _______ .

A. successes

B. totals

C. groups of musicians

D. musical compositions
