Many adults may think they are getting enough shut-eye, but in a major sleep study almost 80 percent of respondents admitted to not getting their prescribed amount of nightly rest. So, what exactly is the right amount of sleep? Research shows that adults need an average of seven to nine hours of sleep a night for optimal functionality. Read on to see just how much of an impact moderate sleep deprivation can have on your mind and body.By getting less than six hours of sleep a night, you could be putting yourself at risk of high blood pressure. When you sleep, your heart gets a break and is able to slow down for a significant period of time. But cutting back on sleep means your heart has to work overtime without its allotted break. In constantly doing so, your body must accommodate to its new conditions and elevate your overall daily blood pressure. And the heart isn’t the only organ that is overtaxed by a lack of sleeps. The less sleep you get, the less time the brain has to regulate stress hormones, and over time, sleep deprivation could permanently hinder the brain’s ability to regulate these hormones, leading to elevated blood pressure.We all hang around in bed during our bouts of illness. But did you know that skipping out on the bed rest can increase your risk of getting sick? Prolonged sleep deprivation has long been associated with diminished immune functions, but researchers have also found a direct correlation between “modest” sleep deprivation — less than six hours — and reduced immune response. So try to toughen up your immune system by getting at least seven hours of sleep a night, and maintaining a healthy diet. You’ll be glad you got that extra hour of sleep the next time that bug comes around and leaves everyone else bedridden with a fever for three days.During deep REM sleep, your muscles (except those in the eyes) are essentially immobilized in order to keep you from acting out on your dreams. Unfortunately, this effort your body makes to keep you safe while dreaming can sometimes backfire, resulting in sleep paralysis. Sleep paralysis occurs when the brain is aroused from its REM cycle, but the body remains in its immobilizing state. This can be quite a frightening sensation because, while your mind is slowly regaining consciousness, it has no control over your body, leaving some with a feeling of powerlessness, fear and panic. Most people experience this eerie phenomena at least once in their lives, but those who are sleep deprived are more likely to have panicked episodes of sleep paralysis that are usually accompanied by hallucinations, as well. For a second, imagine all of your memories are erased; every birthday, summer vacation, even what you did yesterday afternoon is completely lost, because you have no recollection of them. It’s a chilling thought, but that is what a life without sleep would be like. Sleep is essential to the cognitive functions of the brain, and without it, our ability to consolidate memories, learn daily tasks, and make decisions is impaired by a large degree. Research has revealed that REM sleep, or dream-sleep, helps solidify the “fragile” memories the brain creates throughout the day to that they can be easily organized and stored in the mind’s long-term cache.1.According to the passage, what is the meaning of “sleep deprivation”？2.Which of the following statements is TRUE according to Paragraph 3?3.Why is there the so-called “sleep paralysis”？4.Which of the following statements is TRUE according to the last paragraph?5.What effects of sleep deprivation on human mind and body are discussed in this passage?

Charles Darwin’s “On the Origin of Species” is credited with sparking evolution’s revolution in scientific thought, but many observers had pondered evolution before him. It was understanding the idea’s significance and selling it to the public that made Darwin great, according to the Arnold arboretum’s new director.William Friedman, the Arnold Professor of Organism and Evolutionary Biology who took over as arboretum director Jan.1 has studied Darwin’s writings as well as those of his predecessors and contemporaries. While Darwin is widely credited as the father of evolution, Friedman said the “historical sketch” that Darwin attached to later printings of his masterpiece was intended to mollify those who demanded credit for their own earlier ideas.The historical sketch grew with each subsequent printing, Friedman told an audience Monday (Jan. 10)，until, by the 6th edition, 34 authors were mentioned in it. Scholars now believe that somewhere between 50 and 60 authors had beaten Darwin in their writings about evolution. Included was Darwin’s grandfather, Erasmus Darwin, a physician who irritated clergymen with his insistence that life arose from lower forms, specifically mollusks.Friedman’s talk, “A Darwinian Look at Darwin’s Evolutionist Ancestors，” took place at the arboretum’s Hunnewell Building and was the first in a new Director’s Lecture Series.Though others had clearly pondered evolution before Darwin, he wasn’t without originality. Friedman said that Darwin’s thinking on natural selection as the mechanism of evolution was shared by few, most prominently Alfred Wallace, whose writing on the subject after years in the field spurred Darwin’s writing of “On the Origin of Species”. Although the book runs more than 400 pages, Friedman said it was never the book on evolution and natural selection that Darwin intended. In 1856, three years before the book was published, he began work on a detailed tome on natural selection that wouldn’t see publication until 1975.The seminal event in creating “On the Origin of Species” occurred in 1858, when Wallace wrote Darwin detailing Wallace’s ideas of evolution by natural selection. The arrival of Wallace’s ideas galvanized Darwin into writing “ On the Origin of Species ” as an “ abstract ” of the ideas he was painstakingly laying out in the larger work. This was a lucky break for Darwin, because it forced him to write his ideas in plain language, which led to a book that was not only revolutionary, despite those who’d tread similar ground before, but that was also very readable.Though others thought about evolution before Darwin, scientific discovery requires more than just an idea. In addition to the concept, discovery requires the understanding of the significance of the idea， something some of the earlier authors clearly did not have 一 such as the arborist who buried his thoughts on natural selection in the appendix of a book on naval timber. Lastly, scientific discovery demands the ability to convince others of the correctness of an idea. Darwin, through “On the Origin of Species，” was the only thinker of the time who had all three of those traits, Friedman said.“Darwin had the ability to convince others of the correctness of the idea，” Friedman said, adding that even Wallace, whose claim to new thinking on evolution and natural selection was stronger than all the others, paid homage to Darwin by titling his 1889 book on the subject, “ Darwinism. ’’1.According to William Friedman, Darwin’s “On the Origin of Species” is great in that __.2.Friedman believes that Darwin attached a “historical sketch” to later printings of his book in an attempt to _.3.In Friedman’s view, Darwin’s originality lies in _____.4.We have learned that at first Darwin intended to write his idea in（）5.Scientific discovery required all the following Except（）

If you happened to be watching NBC on the first Sunday morning in August last summer, you would have seen something curious. There, on the set of Meet the Press, the host, David Gregory, was interviewing a guest who made a forceful case that the U. S. economy had become “very distorted”. In the wake of the recession, this guest explained, high-income individuals, large banks, and major corporations had experienced a “ significant recovery ” ； the rest of the economy, by contrast — including small businesses and “ a very significant amount of the labor force ” 一 was stuck and still struggling. What we were seeing, he argued, was not a single economy at all, but rather “ fundamentally two separate types of economy，” increasingly distinct and divergent.This diagnosis, though alarming, was hardly unique: drawing attention to the divide between the wealthy and everyone else has long been standard fare on the left. (The idea of “two Americas” was a central theme of John Edwards’s 2004 and 2008 presidential runs. ) What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan: iconic libertarian, preeminent defender of the free market, and (at least until recently) the nation’s foremost devotee of Ayn Rand. When the high priest of capitalism himself is declaring the growth in economic inequality a national crisis, something has gone very, very wrong.This widening gap between the rich and non-rich has been evident for years. In a 2005 report to investors, for instance, three analysts at Citigroup advised that “ the World is dividing into two blocs — the Plutonomy and the rest”.In a plutonomy there is no such animal as “the U. S. consumer” or “the UK consumer”，or indeed “the Russian consumer”. There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the “non-rich”，the multitudinous many, but only accounting for surprisingly small bites of the national pie.Before the recession, it was relatively easy to ignore this concentration of wealth among an elite few. The wondrous inventions of the modem economy — Google, Amazon, the iPhone broadly improved the lives of middle-class consumers, even as they made a tiny subset of entrepreneurs hugely wealthy. And the less-wondrous inventions — particularly the explosion of subprime credit — helped mask the rise of income inequality for many of those whose earnings were stagnant.But the financial crisis and its long, dismal aftermath have changed all that. A multi-billion-dollar bailout and Wall Street’s swift, subsequent reinstatement of gargantuan bonuses have inspired a narrative of parasitic bankers and other elites rigging the game for their own benefit. And this, in turn, has led to wider — and not unreasonable — fears that we are living in not merely a plutonomy, but a plutocracy, in which the rich display outsize political influence, narrowly self-interested motives, and a casual indifference to anyone outside their own rarefied economic bubble.1.According to the passage, the U. S. economy （）2.Which of the following statements about today’s super-elite would the passage support?3.What can be said of modern technological innovations?4.The author seems to suggest that the financial crisis and its aftermath（）5.The primary purpose of the passage is to（）

Cancer has always been with us, but not always in the same way. Its care and management have differed over time, of course, but so, too, have its identity, visibility, and meanings. Pick up the thread of history at its most distant end and you have cancer the crab — so named either because of the ramifying venous processes spreading out from a tumor or because its pain is like the pinch of a crab’s claw. Premodem cancer is a lump, a swelling that sometimes breaks through the skin in ulcerations producing foul-smelling discharges. The ancient Egyptians knew about many tumors that had a bad outcome, and the Greeks made a distinction between benign tumors ( oncos) and malignant ones (carcinos). In the second century A. D. , Galen reckoned that the cause was systemic, an excess of melancholy or black bile, one of the body’s four “humors” brought on by bad diet and environmental circumstances. Ancient medical practitioners sometimes cut tumors out, but the prognosis was known to be grim. Describing tumors of the breast, an Egyptian papyrus from about 1600 B. C. concluded: “There is no treatment. ’’The experience of cancer has always been terrible，but，until modem times, its mark on the culture has been light. In the past, fear coagulated around other ways of dying: infectious and epidemic diseases (plague, smallpox, cholera, typhus, typhoid fever) ； “apoplexies” (what we now call strokes and heart attacks) ； and, most notably in the nineteenth century, “consumption” (tuberculosis). The agonizing manner of cancer death was dreaded, but that fear was not centrally situated in the public mind — as it now is. This is one reason that the medical historian Roy Porter wrote that cancer is “the modem disease par excellence,” and that Mukherjee calls it “the quintessential product of modernity.”At one time, it was thought that cancer was a “disease of civilization” belonging to much the same causal domain as “neurasthenia” and diabetes, the former a nervous weakness believed to be brought about by the stress of modem life and the latter a condition produced by bad diet and indolence. In the eighteenth and nineteenth centuries, some physicians attributed cancer — notably of the breast and the ovaries — to psychological and behavioral causes. William Buchan’s wildly popular eighteenth-century text “Domestic Medicine” judged that cancers might be caused by “excessive fear, grief, religious melancholy”. In the nineteenth century, reference was repeatedly made to a “cancer personality”, and in some versions, specifically to sexual repression. As Susan Sontag observed, cancer was considered shameful, not to be mentioned, even obscene. Among the Romantics and the Victorians, suffering and dying from tuberculosis might be considered a badge of refinement; cancer death was nothing of the sort. “It seems unimaginable,” Sontag wrote, “to aestheticize” cancer.1.According to the passage, the ancient Egyptians（） .2.Which of the following statements about the cancers of the past is best supported by the passage?3.Which of the following is the reason for cancer to be called “the modern disease”？4.“Neurasthenia” and diabetes are mentioned because（）5.As suggested by the passage, with which of the following statements would the author most likely agree?
