TEXT 1
While still catchingup to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. “Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men,”according to Dr. Yehuda, chief psychiatrist at New York’s Veteran’s Administration Hospital.
Studies of both animals and humans have shown that sex hormones somehow affects the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressedout female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males.
Adding to a woman’s increased dose of stress chemicals, are her increased “opportunities” for stress. “It’s not necessarily that women don’t cope as well. It’s just that they have so much more to cope with,” says Dr. Yehuda. “Their capacity for tolerating stress may even be greater than men’s,” she observes, “It’s just that they’re dealing with so many more things that they become worn out from it more visibly and sooner.”
Dr. Yehuda notes another difference between the sexes. “I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family numbers, and they tend not to be oneshot deals. The wearandtear that comes from these longer relationships can be quite devastating.”
Adeline Alvarez married at 18 and gave birth to a son, but wad determined to finish college. “I struggled a lot to get the college degree. I was living in so much frustration that that was my escape to go to school, and get ahead and do better.” Later her marriage ended and she became a single mother. “It’s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck.”
Not everyone experiences the kinds of severe chronic stresses, Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez’s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.

TEXT 2
It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors' names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.
No longer. The Internet and pressure from funding agencies, who are questioning why commercial publishers are making money from governmentfunded research by restricting access to it-is making access to scientific results a reality. The Organization for Economic Cooperation and Development (OECD) was just issued a report describing the farreaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.
The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market is estimated at between $7 billion and $11 billion. The International Association of Scientific, Technical and Medical Publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals.
This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three main ones were identified by the report's authors. This is the socalled big deal, where institutional subscribers pay for access to a collection of online journal titles through sitelicensing agreements. There is openaccess publishing, typically supported by asking the author (or his employer) to pay for the paper to be published. Finally, there are openaccess archives, where organizations such as universities or international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed openaccess, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form of the peerreview process, at least for the publication of papers.
26. In the first paragraph, the author discusses
[A] the background information of journal editing.
[B] the publication routine of laboratory reports.
[C] the relations of authors with journal publishers.
[D] the traditional process of journal publication.
27. Which of the following is true of the OECD report?
[A] It criticizes governmentfunded research.
[B] It introduces an effective means of publication.
[C] It upsets profitmaking journal publishers.
[D] It benefits scientific research considerably.
28. According to the text, online publication is significant in that
[A] it provides an easier access to scientific results.
[B] it brings huge profits to scientific researchers.
[C] it emphasizes the crucial role of scientific knowledge.
[D] it facilitates public investment in scientific research.
29. With the openaccess publishing model, the author of a paper is required to
[A] cover the cost of its publication.
[B] subscribe to the journal publishing it.
[C] allow other online journals to use it freely.
[D] complete the peerreview before submission.
30. Which of the following best summarizes the main idea of the passage?
[A] The Internet is posing a threat to publishers.
[B] A new mode of publication is emerging.
[C] Authors welcome the new channel for publication.
[D] Publication is rendered easier by online service.
TEXT 3
In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association (NBA) listed at over seven feet. If he had played last season, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames.
The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today's people-especially those born to families who have lived in the U.S. for many generations-apparently reached their limit in the early 1960s. And they aren't likely to get any taller. "In the general population today, at this genetic, environmental level, we've pretty much gone as far as we can go," says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.
Growth, which rarely continues beyond the age of 20, demands calories and nutrients-notably, protein-to feed expanding tissues. At the start of the 20th century, undernutrition and childhood infections got in the way. But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height-5′9″ for men, 5′4″for women-hasn't really changed since 1960.
Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs. "There are some real constraints that are set by the genetic architecture of the individual organism," says anthropologist William Leonard of Northwestern University.
Genetic maximums can change, but don't expect this to happen soon. Claire C. Gordon, senior anthropologist at the Army Research Center in Natick, Mass., ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, "you could use today's data and feel fairly confident."

[A] illustrate the change of height of NBA players.
[B] show the popularity of NBA players in the U.S..
[C] compare different generations of NBA players.
[D] assess the achievements of famous NBA players.

[A] NonAmericans add to the average height of the nation.
[B] Human height is conditioned by the upright posture.
[C] Americans are the tallest on average in the world.
[D] Larger babies tend to become taller in adulthood.
34. We learn from the last paragraph that in the near future
[A] the garment industry will reconsider the uniform size.
[B] the design of military uniforms will remain unchanged.
[C] genetic testing will be employed in selecting sportsmen.
[D] the existing data of human height will still be applicable.
35. The text intends to tell us that
[A] the change of human height follows a cyclic pattern.
[B] human height is becoming even more predictable.
[C] Americans have reached their genetic growth limit.
[D] the genetic pattern of Americans has altered.
TEXT 4
In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw-having extracted them from the mouths of his slaves.
That's far different image from the cherrytreechopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong and yet most did little to fight it.
More than anything, the historians say, the founders were hampered by the culture of their time. While Washington and Jefferson privately expressed distaste for slavery, they also understood that it was part of the political and economic bedrock of the country they helped to create.
For one thing, the South could not afford to part with its slaves. Owning slaves was "like having a large bank account," says Wiencek, author of An Imperfect God: George Washington, His Slaves, and the Creation of America. The southern states would not have signed the Constitution without protections for the "peculiar institution," including a clause that counted a slave as threefifths of a man for purposes of congressional representation.
And the statesmen's political lives depended on slavery. The threefifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College. Once in office, Jefferson extended slavery with the Louisiana Purchase in 1803; the new land was carved into 13 states, including three slave states.
Still, Jefferson freed Hemings's children-though not Hemings herself or his approximately 150 other slaves. Washington, who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier, such an act would have required legislative approval in Virginia.
36. George Washington's dental surgery is mentioned to
[A] show the primitive medical practice in the past.
[B] demonstrate the cruelty of slavery in his days.
[C] stress the role of slaves in the U.S. history.
[D] reveal some unknown aspect of his life.
37. We may infer from the second paragraph that
[A] DNA technology has been widely applied to history research.
[B] in its early days the U.S. was confronted with delicate situations.
[C] historians deliberately made up some stories of Jefferson's life.
[D] political compromises are easily found throughout the U.S. history.
38. What do we learn about Thomas Jefferson?
[A] His political view changed his attitude towards slavery.
[B] His status as a father made him free the child slaves.
[C] His attitude towards slavery was complex.
[D] His affair with a slave stained his prestige.
39. Which of the following is true according to the text?
[A] Some founding Fathers benefit politically from slavery.
[B] Slaves in the old days did not have the right to vote.
[C] Slave owners usually had large savings accounts.
[D] Slavery was regarded as a peculiar institution.
40. Washington's decision to free slaves originated from his
[A] moral considerations. [B] military experience.
[C] financial conditions. [D] political stand.
