Directions: For each blank in the following passage, choose the best answer from the four choices given in the opposite column. Mark the corresponding letter of your choice with a single bar across the square brackets on your Machine-scoring Answer Sheet.

When we think about addiction to drags or alcohol, we frequently focus on negative aspects, ignoring the pleasures that accompany drinking or drug-taking. 46 the essence of any serious addiction is a pursuit of pleasure, a search for a "high" that normal life does not 47 . It is only the inability to function 48 the addictive substance that is dismaying, the dependence of the organism upon a certain experience and a .49 inability to function normally without it. Thus a person will take two or three 50 at the end of the day not merely for the pleasure drinking provides, but also because he "doesn't feel 51 without them..

52 does not merely pursue a pleasurable experience and need to 53 it in order to function normally. He needs to repeat it again and again. Something about that particular experience makes life without it 54 complete. Other potentially pleasurable experiences are no longer possible, 55 under the spell of the addictive experience, his life is peculiarly 56. The addict craves an experience and yet he is never really satisfied. The organism may be 57 _sated, but soon it begins to crave again.

Finally a serious addiction is58 a harmless pursuit of pleasure by Its distinctly destructive elements. A heroin addict, for instance, leads a 59 life: his increasing need for heroin in increasing doses prevents him from working, from maintaining relationships, from developing in human ways. 60 an alcoholic's life is narrowed and dehumanized by his dependence on alcohol.

PART IV READING COMPREHENSION (60 minutes, 30 points)

Directions: Below each of the following passages you will find some questions or incomplete statements. Each question or statement is followed by four choices marked A, B, C, and D. Read each passage carefully, and then select the choice that best answers the question or completes the statement. Mark the letter of your choice with a single bar across the square brackets on your Machine-scoring Answer Sheet.

Passage 1

It took no time at all for the native Americans who first greeted Christopher Columbus to be all but erased from the face of the earth. For about a thousand years the peaceful people known as the Taino had thrived in modem-day Cuba and many other islands. But less than 30 years after Columbus' arrival, the Taino would be destroyed by Spanish weaponry, forced labor and European diseases. Unlike their distant cousins, the Inca, Aztecs and Maya, the Taino left no pyramids or temples-no obvious signs that they had ever existed.

But it is a mistake to assume-as many scholars have until quite recently that the absence of abundant artifacts meant the Taino were necessarily more primitive than the grander civilizations of Central and South America. They simply used less durable materials: the Taino relied on wood for building and most craftwork, and much of what they made has disintegrated over the centuries. However, thanks largely to two remarkable digs undertaken recently, archaeologists will be able to enrich their knowledge of the Taino.

In a village on the northern coast of Cuba, a Canadian-Cuban team discovered the nearly intact remains of a Taino dwelling buried in the dirt. This site may have been one of the Taino's major centers. Meanwhile, deep in the forests of the Dominican Republic, a U.S.-Dominican team has also made an important discovery: a 240-ft.-deep Taino cenote, or ceremonial well, where hundreds of objects .thrown in as offerings have been preserved in the oxygen-poor Water.

It will take a much longer time to understand the Taino fully, but they have been rescued from the ignoble status of footnotes in the chapter of history that began with the arrival of Columbus.
61. The main idea of Paragraph 1 is

A. Christopher Columbus returned the Taino's greeting with cruelty.

B. The Europeans' coming brought an end to the existence of the Taino.

C. The Taino once prosperous in modem-day Cuba now has no trace on earth.

D. Spanish weaponry would have crashed the Taino but for Columbus' arrival.

62. It is assumed the Taino had a comparatively low civilization mostly because

A. the Taino had produced no written records.

B. the Taino had built no pyramids mid temples.

C. there has been little wooden structure the Taino relied on.

D. there has been few remains showing the life of the Taino's.

63. Which statement is true concerning the Taino?

A. They were enslaved by foreign invaders.

B. They were more warlike than other Indians.

C. They were the most short-lived of all the civilizations.

D. They were buried deep in the dirt or oxygen-poor water.

64. What does the italicized word "ignoble" (in the last sentence) probably mean?

A. unfortunate B. unsuccessful

C. unpromising D. unworthy

Passage 2

Already lasers can obliterate skin blemishes, topically applied drugs can smooth facial lines and injected agents can remove deep wrinkles. Future products will be faster, borer and longer lasting. "New substances will be developed by entrepreneurs," says Brian Mayou, an aesthetic plastic surgeon, "that will be more successful than liquid silicone that we use today to eradicate wrinkles." The next major breakthrough, says Mel Brahmn, plastic surgeon and chief executive of the Harley Medical Group, will be laser treatment that needs no recovery period.

Nicholas Lowe, clinical professor of dermatology at the University of Los Angeles, adds: "There will be more efficient anti-oxidants to help reduce sun damage and aging. There will also be substances that increase the production of new collagen and elastic tissue to maintain the elasticity of youthful skin."

Lee Shreider, a research cosmetic chemist, says that we may be able to look better without any kind of operation as semi-permanent make-up gets better.

"Crooked noses will be improved by effectively sealing on shaded colors that either enhance or subdue areas of the face. We will be able to straighten eyebrows and lips making the face more symmetrical-which remains one of the keys to beauty~and even close blocked pores with permanent, custom-designed foundation."

The development of the safe sun tan is a potential gold mine. Being researched at the University of Arizona, but a long way from reality, is the injectable tan. Professor Lowe is optimistic: "There will almost certainly be a safe way of developing a sunless tan that protects against sun damage. In animal research, we've applied creams to guinea pigs that can actually 'turn on' some of the genes that produce pigmentation without any sunlight exposure."

65. What is the main topic of the passage?

A. Inventions in cosmetology.

B. New discovery in face-filling.

C. A bright future for facial make-up.

D. The development of beauty culture.

66. According to the passage, what has been used to remove deep wrinkles?

A. Applied drugs.

B. Liquid silicone.

C. Laser treatment.

D. Anti-oxidant.

67. Paragraph 4 suggests that one could improve effectively one's appearance concerning the nose, eyebrows, lips, etc.

A. by applying certain lotions.

B. by having a beauty operation.

C. by changing the face shape.

D. by blocking several pores.

68. As implied in the last paragraph, the injectable tan is being researched to meet the demand of the people who

A. refuse to be exposed to the sun.

B. refuse to apply suntan creams.

C. want to get a tan for beauty.

D. want to try gene pigmentation.

Passage 3

There are faults which age releases us from, and there are virtues, which turn to vices with the lapse of years. The worst of these is thrift, which m early and middle life is wisdom and duty to practice for a provision against destitution. As time goes on this virtue is apt to turn into the ugliest, cruelest, shabbiest of the vices. Then the victim of it finds himself storing past all probable need of saving for himself or those next him, to the deprivation of the remoter kin of the race. In the earlier time when gain was symbolized by gold or silver, the miser had a sensual joy in the touch, of his riches, m hearing the coins clink In their fall through his fingers, and m gloating upon their increase sensible to the hand and eye. Then the miser had his place among the great figures of misdoing; he was of a dramatic effect, like a murderer or a robber; and something of this bad distinction clung to him even when his coins had changed to paper currency, the clean, white notes of the only English bank, or the greenbacks of our innumerable banks of issue; but when the sense of fiches had been transmuted to the balance in his favor at his banker's, or the bonds in his drawer at the safety-deposit vault, all splendor had gone out of his ~ice. His bad eminence was gone, but he clung to the lust of gain which had ranked trim with the picturesque wrong-doers, and which only ruin from without could save him from, unless he gave his remnant of strength to saving himself from it. Most aging men are sensible of all this, but few have the frankness of that aging man who once said that he who died rich died disgraced, and died the other day in the comparative poverty of fifty millions.

69. This short passage is mainly to tell that

A. man becomes increasingly greedy when getting old.

B. a miser can be honest if he does no wrong act.

C. age can help convert some virtue into a vice.

D. misers all started from trying to be thrifty.

70. According to the passage, one is thought vicious when he

A. gathers up money at the sacrifice of all his family members.

B. practices endless thrifty to guard his people from poverty.

C. stores continuously for his own and his relatives' needs.

D. saves too much but wouldn't spend it for the necessary.

71. The italicized expression "gloating upon" probably means

A. thinking with slight guilt.

B. seeing with much satisfaction.

C. touching with great awe.

D. hearing with little delight.

72. The passage implies that what could stop a miser from lusting for money might be

A. his frankness.

B. his eminence.

C. his death.

D. his glory.

73. The words "in the comparative poverty of fifty millions" at the end of the passage suggests a notion that

A. stinginess may cause a very rich man to die very pitiful.

B. rich people may still take 50 million as comparatively little.

C. one remains discontent with all he's gained until his death.

D. the rich are inconsiderate of the majority that live in poverty.

Passage 4

If a mother pushes her small son in a swing, giving only a light force each time he returns, eventually he will be swinging quite high. The child can do this for himself by using his legs to increase the motion, but both the mother's push and the child's leg movements must occur at the proper moment, or the extent of the swing will not increase. In physics, increasing the swing is increasing the amplitude; the length of the rope on the swing determines its natural oscillation period. This ability of an object to move periodically or to vibrate when stimulated by a force operating in its natural period is called resonance.

Resonance is observed many times without consciously thinking about it; for example, one may find an annoying vibration or shimmy in an automobile, caused by a loose engine mount vibrating with increasing amplitude because of an out-of-round tire. The bulge on the tire slaps the pavement with each revolution; at the natural resonance point~ of the engine mount, it will begin to vibrate. Such vibrations can result in considerable damage if allowed to persist. Anther destructive example of resonance is the shattering of a crystal goblet by the production of a musical tone at the natural resonant point of the goblet. The energy of the sound waves causes vibration in the glass; as its amplitude increases, the motion in the glass exceeds the elasticity of the goblet, and it shatters.

An instrument called a tachometer makes use of the principle of resonance. It consists of many tiny bars, loosely fastened together and arranged so that each bar can slide independently of the others. Movement of the bars causes changes in a dial. When placed next to a rotating motor or engine, the tachometer picks up slight vibrations which are transferred to the resonant bars. These bars begin to move, and the resulting dial may be read to find the revolutions per minute of the motor very quickly.

74. An object, if moving rhythmically when stimulated in a natural period, is said to

A. vibrate.

B. resonate.

C. swing.

D. oscillate.

75. The distance a swing moves from its resting position is called its

A. revolution.

B. movement.

C. frequency.

D. amplitude.

76. A tachometer is an instrument that uses resonance to determine

A. the speed of a motor in revolutions.

B. the frequency at which a motor vibrates.

C. the amplitude of an engine that oscillates.

D. the changes in a dial within a car engine.

77. An annoying vibration can be caused at the natural resonance of the car's engine mount

A. if the engine moves too fast.

B. if the engine's amplitude increases.

C. if a tire gets out of balance.

D. if a damage occurs in the engine.

78. In which of the following cases is it useful to consider the relationship between the length of an oscillating object and its natural period?

A. Adjusting the speed of a car.

B. Adjusting a clock pendulum.

C. Adjusting tire balance.

D. Adjusting engine mounts.

Passage 5

I was introduced to the concept of literacy animator in Oladumi Arigbede's (1994) article on high illiteracy rates among women and school dropout rates among girls. According to Arigbede, literacy animators view their role as assisting in the self-liberating development of people in the world who are struggling for a more meaningful life. Animators are a family of deeply concerned and committed people whose gut-level rejection of mass human pauperization compels them to intervene on the side of the marginalized. Their motivation is not derived from a love of literacy as merely another technical life skill, and they accept that literacy is never culturally or ideologically neutral.

Arigbede writes from her experiences as an animator working with women and men in Nigeria. She believes that literacy animators have to make a clear choice about whose culture and whose ideology will be fostered among those with whom they work. Do literacy educators in the United States consider whether the instruction they pursue conflicts with their students' traditional cultures or community, or fosters illiteracies in learners' first or home languages or dialects and in their orality?

Some approaches to literacy instruction represent an ideology of individualism, control, and competition. Consider, for example, the difference in values conveyed and represented when students engage in choral reading versus the practice of having one student read out loud to the group. To identify as a literacy animator is to choose the ideology of "sharing, solidarity, love, equity, co-operation with and respect of both nature and other human beings". Literacy pedagogy that matches the animator ideology works on maintaining the languages and cultures of millions of minority children who at present are being forced to accept the language and culture of the dominant group. It might lead to assessment that examines the performance outcomes of a community of literacy learners and the social significance of their uses of literacy, as opposed to measuring what an individual can do as a reader and writer on a standardized test. Shor (1993) describes literacy animators as problem-posing, community-based, dialogic educators. Do our teacher-education textbooks on reading and language arts promote the idea that teachers should explore problems from a community-based dialogic perspective?

79. A literacy animator is one who

A. struggles for a more meaningful life.

B. frees people from poverty and illiteracy.

C. is committed to marginalize the illiterate.

D. is concerned with what is behind illiteracy.

80. The author suggests that literacy educators in the US in a way

A. promote students' home languages.

B. force students to accept their culture.

C. teach nothing but reading and writing.

D. consider literacy as of non-neutral nature.

81. Arigbede worked with Nigerians probably to

A. teach American customs and ideology.

B. make a choice of culture to be fostered.

C. reject the values of the dominant class.

D. help maintain Nigerian language and culture.

82. According to the author, "choral reading" may represent

A. individualism.

B. collectivism.

C. competition.

D. immersion.

83. Animator ideology emphasizes more

A. the social function of literacy.

B. students?performance in tests.

C. the dominant group's language.

D. the attainment of life skills.

84. It is implied by the author that, because of the kind of teacher education in the US, teachers there tend to ignore

A. constant development of new teaching approaches.

B. using their own wisdom in problem-solving.

C. talented performances of minority students.

D. community-based literacy enhancement.

Passage 6

Scientists have known for more than two, decades that cancer is a disease of the genes. Something scrambles the DNA inside a nucleus, and suddenly, instead of dividing in a measured fashion, a cell begins to copy itself furiously. Unlike an ordinary cell, it never stops. But describing the process isn't the same as figuring it out. Cancer cells are so radically different from normal ones that it's almost impossible to untangle the sequence of events that made them that way. So for years researchers have been attacking the problem by taking normal cells and trying to determine what changes will turn them cancerous-always without success.

According to a report in the current issue of Nature, a team of scientists based at M.I.T.'s Whitehead Institute for Biomedical Research has finally managed to make human cells malignant---a feat they accomplished with two different cell types by inserting just three altered genes into their DNA. While these manipulations were done only in lab dishes and won't lead to any immediate treatment, they appear to be a crucial step in understanding the disease. This is a "landmark paper," wrote Jonathan Weitzman and Moshe Yaniv of the Pasteur Institute in Paris, in an accompanying commentary.

The dramatic new result traces back to a breakthrough in 1983, when the Whitehead's Robert Weinberg and colleagues showed that mouse cells would become cancerous when subjected to two altered genes. But when they tried such alterations on human cells, they didn't work. Since then, scientists have learned that mouse cells differ from human cells in an important respect: they have higher levels of an enzyme called telomerase. That enzyme keeps caplike structures called telomeres on the ends of chromosomes from getting shorter with each round of cell division. Such shortening is part of a cell's aging process, and since cancer cells keep dividing forever, the Whitehead group reasoned that making human cells more mouselike might also make them cancerous.

The strategy worked. The scientists took connective-tissue and kidney cells and introduce three altered genes---one that makes cells divide rapidly; another that disables two substances meant to rein in excessive division; and a third that promotes the production of telomerase, which made the cells essentially immortal. They'd created a tumor in a test tube. "Some people believed that telomerase wasn't that important," says the Whitehead's William Hahn, the study's lead author. "This allows us to say with some certainty that it is."

85. The problem that has been annoying cancer researchers for years is the difficulty in telling

A. how cancer cells are formed.

B. why cancer cells never stop dividing.

C. why normal cells can mm into cancer cells.

D. how different normal cells are from cancer cells.

86. Whitehead's scientists have succeeded in

A. developing malignant cells in human bodies.

B. making normal human cells cancerous.

C. controlling the change of human cells.

D. changing the genes of cancer cells.

87. In the 1983 experiment, human cells didn't work the way mouse cells did because the former

A. were easier to become aged.

B. checked telomerase in dividing.

C. had short ends of chromosomes.

D. lacked telomeres for cell division.

88. To make human cells more mouselike scientists tried

A. to subject them to two more genes.

B. to keep the division from slowing down.

C. to promote the production of telomerase.

D. to prevent excessive cells copying.

89. One key factor in creating tumor with human cells is

A. lengthening the ends of chromosomes.

B. altering the structure of telomeres.

C. increasing the levels of telomerase.

D. modulating the cell dividing process.

90. According to the passage, the Whitehead research has taken a big step in

A. understanding cancer.

B. curing cancer disease.

C. eliminating cancer.

D. preventing cancer.
