单选题Their efforts at bringing Alice and Grace together ______.

单选题It is a wise father that knows his own child, but today a man can boost his paternal(fatherly)wisdom — or at least confirm that he's the kid's dad. All he needs to do is shell out $ 30 for paternity testing kit(PTK)at his local drugstore — and another $ 120 to get the results. More than 60,000 people have purchased the PTKs since they first become available without prescriptions last years, according to Doug Fog, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $ 2500. Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and latest rage a many passionate genealogists — and supports businesses that offer to search for a family's geographic roots. Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA. But some observers are skeptical, "There is a kind of false precision being hawked by people claiming they are doing ancestry testing," says Trey Duster, a New York University sociologist. He notes that each individual has many ancestors — numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father's line or mitochondrial DNA, which a passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents. Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don't rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may have a lot of data from some regions and not others, so a person's test results may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.

单选题Successful business tends to continue implementing the ideas that made them successful. But in a rapidly changing world, ideas often become obsolete overnight. What worked in the past won't necessarily work in the future. In order to thrive in the future, you must constantly create new ideas for every aspect of your business. In fact, you must continually generate new ideas just to keep your head above water. Businesses that aren't creative about their future may not survive. Although Bill Gates is the richest, most successful man on the planet, he did not anticipate the Internet. Now he's scrambling to catch up. If Bill Gates can miss a major aspect of his industry, it can happen to you in your industry. Your business needs to continually innovate and create its future. Gates is now constantly worried about the future of Microsoft. Here's what he said in a recent interview in U.S. News World Report: "Will we be replaced tomorrow? No. In a very short time frame, Microsoft is an incredibly strong company. But when you look to the two to three-year time frame, I don't think anyone can say with a straight face that any technology company has a guaranteed position. Not Intel, not Microsoft, not Compaq, not Dell, take any of your favorites. And that's totally honest. " You may remember that in 1985 the Cabbage Patch Kids dolls were the best-selling toy on the market. But after Coleco Industries introduced their sensational line of dolls they became complacent and didn't create any new toys worth mentioning. As a result, Coleco went bankrupt in 1988. The most successful businesses survive in the long term because they constantly reassess their situations and reinvest themselves accordingly. The 3M Company has a 15% rule: Employees are encouraged to spend 15% of their time developing new ideas on any project they desire. It's no surprise, then, that 3M has been around since 1902. Most businesses are not willing to tear apart last year's model of success and build a new one. Here's a familiar analogy to explain why they are lulled into complacency; imagine that your business is like a pot of lobsters. To cook lobsters, you put them into a pot of warm water and gradually turn up the heat. The lobsters don't realize they're being cooked because the process is so gradual. As a result, they become complacent and die without a struggle. However, if you throw a lobster into the pot when the water is boiling, it will desperately try to escape. This lobster is not lulled by a slowly changing environment. It realizes instantly that it's in a bad environment and takes immediate action to change its status.

单选题{{B}}Section A{{/B}}{{B}}Directions:{{/B}} Each of the passages is followed by some questions. For each question four answers are given. Read the passages carefully and choose the best answer to each question. Put your choice in the ANSWER SHEET. Passage One (1) Gerald Feinberg, the Columbia University physicist, once went so far as to declare that "everything possible will eventually be accomplished." Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at Feinberg, for one, thought that "they'd succeed even there." (2) It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had already been done or soon would be. What greater cliche was there in the history of science than the comic litany of false it-couldn't-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars' chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 mat dreams of controlled nuclear fission were "moonshine." And those weren't even the worst examples. No, the huffiest of all it-couldn't-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distances, or to the moon, the stars, or wherever else. (3) There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke's Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong." (4) Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as. "A camel cannot pass through the eye of a needle." (Well, unless of course it was a very large needle.) On "It is impossible for a door to be simultaneously open and closed." (Well, unless of course it was a revolving door.) (5) Indeed, watertight examples of the really and truly impossible were so exceptionally hard to come by that paradigm cases turned out to be either trivial or absurd. "I know I will never play the piano like Vladimir Horowitz," offered Milton Rothman, a physicist, "no matter how hard I try". Or, from Scott Lankford, a mountaineer "Everest on roller skates."

单选题What has caused the chronic organ shortage?

单选题When, in the age of automation, man searches for a worker to do the tedious, unpleasant jobs that are impossible to mechanize, he may very profitably consider the ape. If we tackled the problem of breeding for brains with as much as enthusiasm as we devote to breeding dogs of surrealistic shapes, we could eventually produce assorted models of useful primates, ranging in size from the gorilla down to the baboon, each adapted to a special kind of work. It is not putting too much strain on the imagination to assume that geneticists could produce a super-ape, able to understand some scores of words, and capable of being trained for such jobs as picking fruit, cleaning up the litter in parks, shining shoes, collecting garbage, doing household chores, and even baby-sitting (though I have known some babies I would not care to trust with a valuable ape). Apes could do many jobs, such as cleaning streets and the more repetitive types of agricultural work, without supervision, though they might need protection from those exceptional specimens of Homo sapiens who think it amusing to tease or bully anything they consider lower on the evolutionary ladder. For other tasks, such as delivering papers and laboring on the docks, our man-ape would have to work under human overseers; and, incidentally, I would love to see the finale of the twenty-first century version of the Waterfront in which the honest but hairy hero will drum on his chest after—literally taking the wicked labor leader apart. Once a supply of nonhuman workers becomes available, a whole range of low IQ jobs could be thankfully relinquished by mankind, to its great mental and physical advantage. What is more, one of the problems which has plagued so many fictional Utopias would be avoided: There would be none of the deridingly subhuman Epsilons of Huxley's Brave New World to act as a permanent reproach to society, for there is a profound moral difference between breeding sub-men and super-apes, though the end products are much the same. The first would introduce a form of slavery, the second would be a biological triumph which could benefit both men and animals.
