A. In the pitch-black waters of the ocean‘s aphotic zone-depths from 1,000m to the seafloor – Rood eyesight does not count for very much on its own. Caves, in addition, frequently present a similar problem: the complete absence of natural light at any time of the day. This has not stopped some organisms from turning these inhospitable environments into their homes, and in the process, many have created their own forms of light by developing one of the stunning visual marvels of the biological universe – bioluminescence.

B. Many people will encounter bioluminescence at some point in their life, typically in some form of a glowworm, which is found on most continents. North and South America are home to the ―firefly‖, a glowing beetle which is known as a glow-worm during its larvae stage. Flightless glowing beetles and worms are also found in Europe, Asia, Australia, and New Zealand. Less common flies, centipedes, molluscs, and snails have bioluminescent qualities as well, as do some mushrooms. The most dramatic examples of bioluminescence. however, are found deep below the ocean‘s surface, where no sunlight can penetrate at all. Here, anglerfish, cookie-cutter sharks, flashlight fish, lantern fish, gulper eels, viperfish, and many other species have developed bioluminescence in unique and creative ways to facilitate their lives.

C. The natural uses of bioluminescence vary widely, and organisms have learnt to be very creative with its use. Fireflies employ bioluminescence primarily for reproductive means – their flashing patterns advertise a firefly‘s readiness to breed. Some fish use it as a handy spotlight to help them locate prey. Others use it as a lure; the anglerfish, for example, dangles a luminescent flare that draws in gullible, smaller fishes which get snapped up by the anglerfish in an automated reflex. Sometimes, bioluminescence is used to resist predators. Vampire squids eject a thick cloud of glowing liquid from the tip of its arms when threatened, which can be disorientating. Other species use a single, bright flash to temporarily blind their attacker, with an effect similar to that of an oncoming car which has not dipped its headlights.

D. Humans have captured and utilized bioluminescence by developing, over the last decade, a technology known as Bioluminescence Imaging (BLI). BU involves the extraction of a DNA protein from a bioluminescent organism, and then the integration of this protein into a laboratory animal through trans- geneticism. Researchers have been able to use luminesced pathogens and cancer cell lines to track the respective spread of infections and cancers. Through BLI, cancers and infections can be observed without intervening in a way that affects their independent development. In other words, while an ultra-sensitive camera and bioluminescent proteins add a visual element, they do not disrupt or mutate the natural processes. As a result, when testing drugs and treatments, researchers are permitted a single perspective of a therapy‘s progression.

E. Once scientists learn how to engineer bioluminescence and keep it stable in large quantities, a number of other human uses for it will become available. Glowing trees have been proposed as replacements for electric lighting along busy roads, for example, which would reduce our dependence on non-renewable energy sources. The same technology used in Christmas trees for the family home would also eliminate the fire danger from electrical fairy lights. It may also be possible for crops and plants to luminesce when they require watering, and for meat and dairy products to ―tell us‖ when they have become contaminated by bacteria. In a similar way. forensic investigators could detect bacterial species on corpses through bioluminescence. Finally, there is an element of pure novelty. Children‘s toys and stickers are often made with glow-in-the-dark qualities, and a biological form would allow rabbits, mice, fish, and other pets to glow as well.

Reading Passage 2.

CHANGES IN MALE BODY IMAGE

A. The pressures on women to look slender, youthful, and attractive have been extensively documented, but changing expectations for women‘s bodies have varied widely. From voluptuous and curvy in the days of Marilyn Monroe to slender and androgynous when Twiggy hit the London scene in the mid- 1960s, and then on to the towering Amazonian models of the 1980s and the ―heroin chic‖ and size-zero obsession of today, it is not just clothes that go in and out of fashion for women. The prevailing notion of the perfect body for men, however, has remained remarkably static: broad shoulders, a big chest and arms, and rippling, visible abdominal muscles and powerful legs have long been the staple ingredients of a desirable male physique.

B. A growing body of evidence suggests this is changing, however. Rootsteins, a mannequin design company in Britain, has released its newest male model – the Homme nouveau – with a cinched-in 27- inch waist. “To put that into perspective,” says one female fashion reporter, “I had a 27-inch waist when I was thirteen _ and I was really skinny.” The company suggests that the Homme nouveau “redress the prevailing ‘beefcake‘ figure by carving out a far more streamlined, sinuous silhouette to match the edgier attitude of a new generation”.

C. Elsewhere in the fashion industry, the label American Apparel is releasing a line of trousers in sizes no larger than a 30-inch waist, which squeezes out most of the younger male market who have an average waistline over five inches larger. Slender young men are naturally starting to dominate the catwalks and magazine pages as well “No one wanted the big guys,” model David Gandy has said, describing how his muscled physique was losing him jobs. “It was all the skinny, androgynous look. People would look at me very, very strangely when I went to castings.”

D. Achieving such a physique can be unattainable for those without the natural genetic make-up. “I don‘t know that anyone would consider my body archetypal or as an exemplar to work towards,” notes model Davo McConville. “You couldn‘t aim for this; it‘s defined by a vacuum of flesh, by what it‘s not.” Nevertheless, statistics suggest it is not just an obsession of models, celebrities, and the media – more and more ordinary men are prepared to go to great lengths for a slender body. One indication is the growing number of men who are discovering surgical reconstruction. Male breast reduction has become especially popular, in 2009, the year-on-year growth rate for this procedure rose to 44 per cent in the United Kingdom. Liposuction also remains popular in the market for male body reconstructive surgery, with 35,000 such procedures being performed on men every year.

E. Additionally, more men now have eating disorders than ever before. These are characterized by normal eating habits, typically either the consumption of insufficient or excessive amounts of food. Eating disorders are detrimental to the physical and mental condition of people who suffer from them, and the desire to achieve unrealistic physiques has been implicated as a cause. In 1990, only 10% of people suffering from anorexia or bulimia were believed to be male, but this figure has climbed steadily to around one-quarter today. Around two in five binge eaters are men. Women still make up the majority of those afflicted by eating disorders, but the perception of it being a “girly” problem has contributed to men being less likely to pursue treatment. In 2008, male eating disorders were thrust into the spotlight when former British Deputy Prime Minister, John Prescott, admitted to habitually gorging on junk food and then inducing himself to vomit while in office. “I never admitted to this out of the shame and embarrassment,” he said. ―I found it difficult as a man like me to admit that I suffered from bulimia.”

F. In some respects, the slim male silhouette seems to be complementing, rather than displacing, the G. I. Joe physique. Men‘s Health, one of the only titles to weather the floundering magazine market with sales increasing to a quarter of a million per issue, has a staple diet of bulky men on the cover who entice readers with the promise of big, powerful muscles. Advertising executives and fashion editors suggest that in times of recession and political uncertainty, the more robust male body image once again becomes desirable. Academic research supports this claim, indicating that more “feminine” features are desirable for men in comfortable and secure societies, while “masculine” physical traits are more attractive where survival comes back to the individual. A University of Aberdeen study, conducted using 4,500 women from over 30 countries, found a pronounced correlation between levels of public healthcare and the amount of effeminacy women preferred in their men. In Sweden, the country considered to have the best healthcare, 68 per cent of women preferred the men who were shown with feminine facial features. In Brazil, the country with the worst healthcare in the study, only 45 per cent of women were so inclined. “The results suggest that as healthcare improves, more masculine men fall out of favour,” the researchers concluded.

G. Ultimately, columnist Polly Vernon has written, we are left with two polarized ideals of masculine beauty. One is the sleek, slender silhouette that exudes cutting-edge style and a wealthy, comfortable lifestyle. The other is the ‘strong, muscular, austerity-resistant” form that suggests a man can look after himself with his own bare hands. These ideals co-exist by pulling men in different directions and encouraging them to believe they must always be chasing physical perfection, while simultaneously destabilizing any firm notions of what physical perfection requires.

H. As a result, attaining the ideal body becomes an ever more futile and time-consuming task. Vernon concludes that this means less time for the more important things in life, and both sexes should resist the
compulsive obsession with beauty.

EATS, SHOOTS AND LEAVES. A BOOK REVIEW

A. The title of Eats, Shoots and Leaves refers to a famously misplaced comma in a wildlife manual that ended up suggesting a panda rather violently ―eats, shoots and leaves‖ instead of eating shoots andleaves. The author of this book, journalist Lynne Truss, is something akin to a militant linguist, dedicating this “zero tolerance” manifesto on grammar to the striking Bolshevik printers of St. Petersburg who, in demanding the same remuneration for punctuation as they received for letters, ended up setting in motion the first Russian Revolution.

B. Some of the books involve humorous attacks on erroneous punctuation. There is the confused Shakespearian thespian who inadvertently turns a frantic plea: “Go, get him surgeons!” into the cheerful encouragement of “Go get him, surgeons!” Street and shop signs have a ubiquitous presence. A bakery declares “FRESH DONUT‘S SOLD HERE” and a florist curiously announces that “Pansy‘s here!” (Is she?). The shameless title of a Hollywood film Two Weeks Notice is reeled in for criticism – “Would they similarly call it One Weeks Notice?”, Truss enquires – and sometimes, as in the case of signs promoting “ANTIQUE‘S” and “Potatoe‘s” – one questions whether we are bearing witness to new depths of grammar ignorance, or a postmodern caricature of atrocious punctuation.

C. Eats, Shoots and Leaves is not just a piece of comedy and ridicule, however, and Truss has plenty to offer on the question of proper grammar usage. If you have ever wondered whether it is acceptable to simply use an “em dash” in place of a comma – the verdict from Truss is that you can. “The dash is less formal than the semicolon, which makes it more attractive,” she suggests. “It enhances conversational tone; and … it is capable of quite subtle effects.” The author concludes, with characteristic wry condescension, that the em dash‘s popularity largely rests on people knowing it is almost impossible to use incorrectly. A truss is a personal champion of the semicolon, a historically contentious punctuation mark elsewhere maligned by novelist Kurt Vonnegut Jr., as a “transvestite hermaphrodite representing absolutely nothing”. Coming to the semicolon‘s defence. Truss suggests that while it can certainly be overused, she refers to the dying words of one 20th century writer: “I should have used fewer semicolons, the semicolon can perform the role of a kind of Special Policeman in the event of comma fights.”

D. Truss has come under criticism on two broad points. The first argument criticises the legitimacy of her authority as a punctuation autocrat. Louis Menand, writing in the New Yorker, details Eats, Shoots and Leaves‘ numerous grammatical and punctuation sins: a comma-free non-restrictive clause; a superfluous ellipsis; a misplaced apostrophe; a misused parenthesis; two misused semicolons; an erroneous hyphen in the word “abuzz”, and so on. In fact, as Menand notes, half the semicolons in the Truss book are spuriously deployed because they stem from the author‘s open flouting of the rule that semicolons must only connect two independent clauses. “Why would a person not just vague about the rules but disinclined to follow them bother to produce a guide to punctuation?” Menand inquires. Ultimately, he holds Truss accused of producing a book that pleases those who “just need to vent” and concludes that Eats, Shoots and Leaves is actually a tirade against the decline of language and print that disguises itself, thinly and poorly, as some kind of a style manual.

E. Linguist David Chrystal has criticised what he describes as a “linguistic purism” coursing through Truss‘ book. Linguistic purism is the notion that one variety of language is somehow more-pure than others, with this sense of purity often based on an idealised historical point in the language‘s development, but sometimes simply in reference to an abstract idea. In The Fight for English: How Language Pundits Ate, Shot and Left, Chrystal – a former colleague of Truss – condemns the no-holds- barred approach to punctuation and grammar. “Zero tolerance does not allow for flexibility,” he argues. “It is prescriptivism taken to extremes. It suggests that language is in a state where all the rules are established with 100 per cent certainty. The suggestion is false. We do not know what all the rules of punctuation are. And no rule of punctuation is followed by all of the people all of the time.”

F. Other detractors of Truss‘ “prescriptivism” are careful to disassociate needless purism from robust and sensible criticism, an oppositional stance they call descriptivism. “Don‘t ever imagine,” Geoffrey K. Pullum on the Language Log emphasises, “that I think all honest attempts at using English are just as good as any others. [ Bad writing needs to be fixed. But let‘s make sure we fix the right things.” In other words, we do not require a dogmatic approach to clean up the misused language. Charles Gaulke concurs, noting that his opposition to “prescriptivism” does not require contending with the existence of standards themselves, but questioning whether our standards should determine what works, or whether what works should determine our standards.

G. Ultimately, it is unlikely the purists and pedagogues will ever make absolute peace with those who see language as a fluid, creative process within which everyone has a role to play. Both sides can learn to live in a sort of contentious harmony, however. Creativity typically involves extending, adapting and critiquing the status quo, and revising and reviving old traditions while constructing new ones. Rules must exist in order for this process to take place, if only for them to be broken. On the flip side, rules have an important role to play in guiding our language into forms that can be accessed by people across all manner of differences, so it is vital to acknowledge the extent to which they can be democratic, rather than merely autocratic in function. Nevertheless, all the regulations in the world cannot stem the natural spring of language, which bursts through rivets and snakes around the dams that linguistic authorities may try to put in place. We should celebrate rather than curse these inevitabletensions.
