2、xt 1With advancing age, our bodies experience an inevitable loss of bone. Two major studies in elderly populations now underscore the importance of dietary protein in this structural erosion, which can lead to osteoporosis. The reports come to sharply different conclusion, however, about the effect
3、of animal protein on the rate of bone loss. In one study, diets rich in animal protein correlated with greater bone loss and fracture risk. In the other, animal protein appeared to protect bone. Such contradictions, “which are not very satisfying”, often emerge from observational studies where resea
4、rchers record the natural habits and health of people, notes Robert P. Heaney of Creighton University Medical Center in Omaha, Neb. “Thats not a criticism of such studies,” he says, “just a reminder of the uncontrollable variables common in populations.”However, he notes, the new studies are importa
5、nt because theyre in the vanguard of efforts to understand proteins impact on age-related bone loss. This condition underlies a growing U.S. epidemic of hip fractures. Treating them costs more than $ 10 billion annually.The first of the new analyses computed bone loss over 7 years in some 750 elderl
6、y women, all taking part in a larger osteoporosis study thats been running since 1986 at four U.S. sites.Women eating the most animal proteinroughly four times their vegetable protein intakelost 0.8 percent of the bone in their hips annually, notes endocrinologist Deborah E. Sellmeyer, director of t
7、he University of California, San Francisco-Mount Zion Osteoporosis Center. This is four times the rate of bone loss in participants who ate about equal parts animal and vegetable protein. The risk of hip fractures in women eating the highest proportion of animal protein was 3.7 times that in women r
8、egularly downing equal quantities of animal and vegetable protein, the team reports in the January America Journal of Clinical Nutrition.The findings make sense, Sellmeyer argues, because digestion of animal protein releases large amounts of acid that the kidneys must excrete. Previous studies showe
9、d that when kidney function decreases with age and calcium intake drops, the body draws upon skeletal calcium to buffer the resulting buildup of acid, thus eroding bone. Most of the women in this study consumed only about half of the 1,500 milligrams of daily calcium recommended for people their age
10、.1. Which of the following statements about observational studies is true?A They often lead to contradictive conclusions.B They remind people of the uncontrollable variables in life.C They are often criticized by researchers.D Researchers record the natural habits and health of people by them. 2. Ac
11、cording to Heaney, why are the two studies important?A Because they reduce the number of U.S. epidemic of hip fractures.B Because they are the first to study proteins effect on bone loss of elders.C Because they cost more than $10 billion annually.D Because they show observational studies can lead t
12、o contradictive conclusion.3. According to the text, the first study shows A elderly women take in more animal protein than vegetable protein.B digestion of animal protein releases more acid than that of vegetable protein. C diets rich in animal protein will lead to greater bone loss and fracture ri
13、sk.D there are many uncontrollable variables in populations.4. According to previous studies, which of the following is true? A The amount of acid released by digestion of animal protein increases as people age.B Most elderly women can only take in about half of the required amount of calcium.C As p
14、eople age, the kidney function and calcium intake increase.D The skeletal calcium will decrease if people cant take in enough calcium.5. The author may go on to talk aboutA the suitable amount of animal protein for elderly people to take.B how to improve the intake of calcium.C the report of the sec

The Society has a wide experience of insurance c
16、ompanies and of the terms offered by their policies, and places insurance with many companies who are able to provide the cover which the Society considers necessary. You may like the Society to insure with a particular company, and if so please contact immediately the Branch Office to which you sub
17、mitted your application for loan, and so long as that company and its terms are acceptable to the Society the cover will be arranged accordingly. If you should suggest a company and it is not one with which the Society does business you will be informed and offered a choice of other companies. You m
18、ay request change of insurance company at any time during the life of the mortgage. If your mortgage is under the endowment scheme or supported by an insurance guarantee or if the documents of title specify the company to be used it may not be possible to accept your choice. The initial sum insured
19、will be the figure shown under the heading “Amount of Property Insurance” in the Details of Loan. This figure is the amount recommended by the Societys value, as his estimate of the replacement cost of the building at the date of valuation, unless some other amount has been agreed in writing between
20、 you and the Society. No warranty is given or implied that the amount of insurance will cover complete loss. You are reminded that the market value of your property bears no relationship to the cost of replacement. The amount for which the property is insured should therefore represent not less than
21、 the cost, at the time of repair or replacement, of rebuilding all the property covered in the same materials, form, style and condition as when it is new. It should also include in complying with the requirements of the Local Authority and in removing debris, etc. The term“property” includes domest
22、ic outbuilding, garages, walls, landlords fixtures and fittings, etc., but excludes the value of the land. The market value of a house is therefore likely to be less than the cost of rebuilding, especially if the property is elderly. Even if the property is recently built, the work involved in reins
23、tatement will be more expensive than the building cost which can be achieved by a builder building on an estate basis.6. Where is the text probably taken from?A An advertisement. B An information booklet.C A newspaper article. D A formal speech. 7. If a customer suggests an insurance company，A the S
24、ociety may not be able to agree to the company.B the Society will provide a list of alternative companies. C the Society will not accept responsibility for the policy.D it is impossible to change that company later on.8.Which of the following is true when you insure your property?A You should use th
25、e market value as a guide.B You should take the advice of your Local Authority.C Garages and garden sheds are not usually included.D You should not take the land value into account.9.When does rebuilding a property cost more than its market value?A Only if the property is old.B Particularly if the p
26、roperty is new.C Whatever the age of the property.D As the cost of rebuilding rises.10.We can infer from the text thatA the Society is experienced in offering suggestions to insurance companies.B the insurance company will refuse your application if your choice violate its rules.C after evaluation,
27、the initial sum insured will be figured out by the Societys value.D the amount for which the property is insured is required by the Local Authority.Text 3Imagine that I have $100 and I offer you $ 20 of it, no strings attached. Youd take it, right? Any fool would; its a windfall. But imagine further
28、 that you know I must give away part of my $ 100 or lose it all. All of a sudden my motives arent entirely altruistic, but Im still offering you free money. Take it or leave it, but no negotiation allowed. How would you feel? What would you do?If you were like a lot of people who have answered these
29、 questions in a psychological experiment over the years, you would now feel conflicted. Many of these people actually walked away from the deal, even though it would have meant a no-strings-attached twenty bucks in their pockets. Why? Because the arrangement is fundamentally unfair, and once you kno
30、w this your basic sense of moral indignation clicks in. Your emotions and principles trump your pure rationality.Psychologists have demonstrated this in the laboratory, time and time again. Its known as the Ultimatum Game, and its counterintuitive findings are part of a broad new understanding of ho
31、w the human brain and mind work. Consider another experiment from the emerging field of social neuroscience. Psychologist John Bargh flashed words in front of volunteers, but so rapidly that they did not register in the conscious mind. Some of the words had to do with rudeness (like impolite and obn
32、oxious) while others were the opposite (respect, considerate). The volunteers were later put in a simulated situation in which they could be civil toward one anotheror not. Many who had seen the words associated with rudeness were not. Two-thirds of the volunteers who had been primed with rudeness w
33、ords interrupted another person afterward, compared to only 16 percent of those primed with politeness words.Marketers and politicians are already familiar with these advances in brain science, and are using this knowledge to control our behavior. Advertisements are deliberately designed to target t
34、he emotional brain and create bonds, even cravings (one of our basest and most powerful emotional drives). Extensive research shows that our brains have certain hardwired inclinations that might be exploited. For example, our brains tend to register frequently heard facts as true, even if they are p
35、atently false. As a result, our memories and beliefs are highly malleable and unreliable. We also tend, if unchecked by the conscious reasoning mind, to focus overly on risk, inconvenience, hasslesanything negative. And researchers have found that we all carry around an innate hostility toward “othe
36、rness,” which means anyone not like us. Despite remarkable progress in understanding the brains anatomy and biochemistry, the organ is far too complex an array of interconnected circuits to be that easily manipulated with simple subconscious stimuli. Advertisers may be disappointed to hear it, but t
37、here is no “Buy now!” switch hidden among the neurons and synapses.11. 100 dollar deal suggests thatA money is nothing compared with moral principles.B where there is no pain, there is no gain.C emotional reaction often overpowers rational thinking.D a motive is often at work when money is given awa
38、y.12. John Barghs experiment wanted to find outA whether words were better memorized through conscious training.B how peoples minds reacted to words of rudeness or politeness.C how the emotional parts of our brains can be manipulated.D what kind of words had the greatest effect on peoples minds.13.
39、Politician can persuade us to believe what is apparently false byA creating our desire for it. B repeating it frequently.C bringing it to our conscious mind. D pretending to reject it themselves.14. What can we infer from the last paragraph?A Some findings in modern neuroscience have been misused,B
40、Not many advertisements are as well-written as they should be.C Peoples subconscious mind is not so easily manipulated.D There are many things yet unknown to todays neuroscientists.15. Which of the following is closest to the messge the text tries to convey?A The latest advances in neuroscience. B M
41、arketing and mind control.C Advertisement writing techniques. D The conflict between emotions and principles.Text 4The making of classifications by literary historians can be a somewhat risky enterprise. When Black poets are discussed separately as a group, for instance, the extent to which their wo
42、rk reflects the development of poetry in general should not be forgotten, or a distortion of literary history may result. This reminder is particularly relevant in an assessment of the differences between Black poets at the turn of last century (1900-1909) and those of the generation of the 1920s. T
43、hese differences include the bolder and more forthright speech of the later generation and its technical inventiveness. It should be remembered, though, that comparable differences also existed for similar generations of White poets.When poets of the 1910s and 1920s are considered together, however,
44、 the distinctions that literary historians might make between “conservative” and “experimental” would be of little significance in a discussion of Black poets, although these remain helpful classifications for White poets of these decades. Certainly differences can be noted between “conservative” Bl
45、ack poets such as Countee Cullen and Cluade McKay and “experimental” ones such as Jean Toomer and Langston Hughes. But Black poets were not battling over old or new styles; rather, one accomplished Black poet was ready to welcome another, whatever his or her style, for what mattered was racial pride
46、.However, in the 1920s Black poets did debate whether they should deal with specifically racial subjects. They asked whether they should only write about Black experience for a Black audience or whether such demands were restrictive. It may be said, though, that virtually all these poets wrote their
47、 best poems when they spoke out of racial feeling, race being, as James Weldon Johnson rightly put it, “inevitably the thing the Negro poet knows best.”At the turn of the 20th century, by contrast, most Black poets generally wrote in the conventional manner of the age and expressed noble, if vague,
48、emotions in their poetry. These poets were not unusually gifted, though Roscoe Jamision and G. M. McClellen may be mentioned as exceptions. They chose not to write in dialect, which, as Sterling Brown has suggested, “meant a rejection of stereotypes of Negro life,” and they refused to write only abo
49、ut racial subjects. This refusal had both a positive and a negative consequence. As Brown observes, “Valuably insisting that Negro poets should not be confined to issues of race, these poets committed (an) error. they refused to look into their hearts and write.” These are important insights, but one must stress that this refusal to look within was also typical of most White poets of the United States at the t
