Even though cultures widely assume that boys are stronger and sturdier than girls, basic biological weaknesses are built into the male of our species. First of all, human males seem to be slowly disappearing. Mother Nature has always acknowledged and compensated for the fragility and loss of boys by arranging for more of them: 106 male births to 100 female newborns over the course of human history. But in recent decades, from the United States to Japan, from Canada to northern Europe, wherever researchers have looked, the rate of male newborns has declined. Examining US birth records for the years between 1970 and 1990, they found 1.7 fewer boys per 1,000 than in decades and centuries past; Japan's loss in the same decades was 3.7 boys.Boys are also more than two-thirds more likely than girls to be bom prematurely before the 37th week of pregnancy. And, despite advances in public health, boys in the 1990s faced a 30 percent higher chance of death by their first birthday than girls; in contrast, back in the 1750s, they were only 10 per cent more likely than girls to die so early in their lives. Once they make it to childhood, boys face other challenges. They are more prone to a range of neurological disorders. Autism 自闭症 is notoriously higher among boys than girls: now nearly five times more likely, as tallied by the US Centers for Disease Control and Prevention. They are more susceptible than girls to damage from very low-level exposure to lead. Yet another problem: boys suffer from asthma at higher rates. There's also a stronger link between air pollution and autism in boys.Why do boys face such a burden of physical challenges? The answer is that the male’s problems start in the womb: from his more complicated fetal development, to his genetic makeup, to how his hormones work. The nine-month transformation from a few cells to an infant is a time of great vulnerability. Many chronic illnesses are seeded in the womb. In our species, the female is the default gender, the basic simpler model: Humans start out in the womb with female features (that is why males have nipples). The complicated transformation in the womb from female to male exposes the male to a journey packed with special perils. When the first blast of testosterone 睾酮 from the Y gene comes along at about the eighth week, the unisex brain has to morph into a male brain, killing off some cells in the communication centers and growing more cells in the sex and aggression centers. The simpler female reproductive system has to turn into the more complex male reproductive tract, developing tissues such as the testis and prostate 前列腺.Further, it takes a greater number of cell divisions to make a male; with each comes the greater risk of an error as well as the greater vulnerability to a hit from pollutants.On top of that challenge, the human male’s XY chromosome 染色体 combination is simply more vulnerable. The two XXs in the female version of our species offer some protection: In disorders where one X chromosome has a genetic defect, the female’s healthy backup chromosome can take over. But with his single X chromosome, the male lacks a healthy copy of the gene to fall back on. The X chromosome, which never shrank, is also a larger chromosome “with far more genetic information than the Y chromosome,’’ finds Irva Hertz-Piciotto, a University of California at Davis autism researcher, “so there may be some inherent loss of key proteins for brain development or repair mechanisms in boys.” This is a clue to the higher autism rate among boys, she asserts.Females also have a stronger immune system because they are packed with estrogen 雌激素,a hormone that counteracts the antioxidant process. “Estrogen protects the brain,” explains Theodore Slotkin, professor of neurobiology at Duke University's School of Medicine. “It repairs and replaces, even after neural injury,” Low estrogen even leaves boys more sensitive to head injuries. The male brain “is simply a more fragile apparatus, more sensitive to almost all brain insults,” says lead poisoning expert Herbert Needleman.It is the high levels of testosterone in the womb at critical times in gestation, according to British psychopathologist Simon Baron-Cohen, that are responsible for what he calls “the extreme male brain” -- the kind exhibited by autistic boys - low in empathy, high in systematizing. And in fact US researchers in recent decades have found unusually low estrogen and high testosterone levels among boys with autism. If the balance of hormones is out of whack in males, what made that happen? Researchers are coming up with some clues. In the New York City neighborhoods near Columbia University's Center for Children’s Environmental Health, families for years routinely sprayed their apartments with a popular insecticide, chlorpyrifos, until it was banned from household use in 2001. The researchers found that prenatal exposure to the chemical seemed to have more of an effect on reducing the IQs of boys than girls. Disruption of their male hormones may be the reason, “One possible explanation for the greater sensitivity of boys to chlorpyrifos is that the insecticide acts as an endocrine disruptor 肉分泌'干扰素 to suppress sex-specific hormones,” said study leader Megan Horton of Columbia.Similarly, pregnant mothers' exposure to phthalates 邻苯二甲酸酉旨一used in making some vinyl 乙矯基 products and toys as well as some personal care products - has been linked to bigger changes in the behavior, such as aggression and attention problems, of their sons than their daughters. Phthalates also may feminize male genitalia.Boys also seem to be more vulnerable to bisphenol A, an estrogenic substance used to make polycarbonate plastics as well as the linings of food and beverage cans. Boys, but not girls, exposed to higher bisphenol A levels in the womb or during childhood had more hyperactivity, aggression and anxiety problems, according to a University of California at Berkeley study. In addition, pregnant women exposed to higher levels of the chemical gave birth to baby boys with lower thyroid hormones 甲状腺激素.No such effect was detected in the baby girls. No one knows what these lower levels may mean for the boys’ health because they remained within normal boundaries, but it could have important effects because thyroid hormones guide brain development.Some of these chemicals act like fake estrogens, others like fake testosterone, but both types seem to disrupt normal development. Animal tests show that a dose of these chemicals inflict the most damage when it hits a fetus. And, because of their biological vulnerabilities, it is boys who may experience the most effects. While not forgoing the push for fairness and equality, it seems wise to accept the scientific reality of male weaknesses. This likely won't mean the end of men, but their vulnerability to environmental contaminants and diseases could have serious ramifications for the future of the entire human race unless we find ways to protect them from harm.1.If text B is accurate, then the evidence for the assertion that human males are gradually disappearing is(  ) .2.Compared with girls, boys are(  ) .3.Nipples in humans are found on the(  ) .4.In paragraph 10 the author asserts that chronic diseases(  ) .5.Backup in paragraph 11 means something that (  ).6.The levels of thyroid hormones in new bom males, mentioned in paragraph 16, (  ).7.Imagine that environmental pollution continues at current or higher levels in China.

1. Twelve months ago, Lululemon Athletica was one of the hottest brands in the world. Sales of its high-priced yoga gear were exploding; the company was expanding into new markets; experts were in awe of its “cult-like following.” As one observer put it, “They’re more than apparel. They’re a life style.” But then customers started complaining about pilling fabrics, bleeding dyes and, most memorably, yoga pants so thin that they effectively became transparent when you bent over. Lululemon's founder made things worse by suggesting that some women were too fat to wear the company’s clothes. And that was the end of Lululemon’s charmed existence: the founder stepped down from his management role, and, a few weeks ago, the company said that it had seen sales “decelerate meaningfully.”2. It’s a truism of business school thinking that a company's brand is its “most important asset,” more valuable than technology or patents or manufacturing prowess. But brands have never been more fragile. The reason is simple: consumers are supremely well informed and far more likely to investigate the real value of products than to rely on logos. Absolute Value, a new book by Itamar Simonson, a marketing professor at Stanford, and Emanuel Rosen, a former software executive, shows that, historically, the rise of brands was a response to an information-poor environment. When consumers had to rely on advertisements and their past experience with a company, brands served as proxies for quality; if a car was made by General Motors, or a ketchup by Heinz, people assumed that it was pretty good. It was hard to figure out if a new product from an unfamiliar company was reliable or not, so brand loyalty was a way of reducing risk. As recently as the 1980s, nearly four-fifths of American car buyers stayed loyal to a brand.3. Today consumers can read reams of research about whatever they want to buy. Thisstarted back with Consumer Reports, which published objective studies of products, and with JD Power's quality rankings, which revealed what ordinary customers thought of the cars they had bought. But what has really weakened the power of brands is the internet, which has given ordinary consumers easy access to expert reviews, user reviews and detailed product data, in an array of categories. A recent PricewaterhouseCoopers study found that 80 percent of consumers look at online reviews before making major purchases, and a host of studies have logged the strong influence those reviews have on the decisions people make. The rise of social media has accelerated the trend to an astonishing degree: a dud product can become a laughingstock in a matter of hours. In the old days you might buy a Sony television set because you had owned one before, or because you trusted the brand. Today such considerations matter much less than reviews on Amazon and Engadget and CNET. As Simonson told me, “each product now has to prove itself on its own.”4. It has been argued that the welter of information will actually make brands more valuable. As the influential consultancy Interbrand puts it, “In a world where consumers are often overwhelmed with information, the role a brand plays in people’s lives has become all the more important.” But information overload is largely a myth. “Most consumers learn very quickly how to get a great deal of information efficiently and effectively,” Simonson says. "Most of us figure out how to find what we’re looking for without spending huge amounts of time on line." And this has made customer loyalty pretty much a thing of the past. Only 25 percent of American respondents in a recent Ernst & Young study said that brand loyalty affected how they shopped.5. For established brands this is a nightmare. You can never coast on past performance — the percentage of brand-loyal car buyers has plummeted in the past twenty years — and the price premium that a recognized brand can charge has shrunk. If you are making a better product, you can still charge more, but, if your product is much like that of your competitors, your price needs to be similar too. That is the clearest indication that the economic value of brands — traditionally assessed by the premium a company could charge — is waning. This isn’t true across the board: brands retain value where the brand association is integral to the experience of a product (Coca-Cola, say), or where they confer status, as with luxury goods. But even here the information deluge is transformative; luxury travel, for instance, has been profoundly affected by websites like TripAdvisor.6. For consumers this is ideal: they are making better choices, and heightened competition has raised quality and held down prices. And they are not the only beneficiaries; upstarts now find it easier to compete with the big boys. If you build a better mousetrap, people will soon know about it. A decade ago, personal-computer companies like Asus and Acer had almost no brand identity outside Taiwan. Now they are major players. Roku, a maker of streaming entertainment devices, has thrived even though its products have to compete with similar ones made by Apple (which is usually cited as the world's most valuable brand). And the Korean carmaker Hyundai has gone from being a joke to selling four million cars a year. For much of the 20th century, consumer markets were stable. Today they are tumultuous, and you are only as good as your last product. For brands like Lululemon there is only one consolation: make something really great and your past sins will be forgotten.1.According to text A, which was published recently, within the past year Lululemon Athletica(  ) . 2.The best opposite of the verb to decelerate (used in paragraph 1) is to (  ).3.A company's brand is its “most important asset”'(paragraph 2).
