单选题Women have been driving yellow cabs in New York since the 1940s, but 99% of drivers are male. Even among drivers of cars booked by phone or online, only 4% are women. That may change with the launch of SheTaxis, an app that lets female passengers insist on female drivers, and vice versa. It will be available in New York City, Westchester and Long Island, and the firm plans to expand to other cities. Stella Mateo, the founder, is betting that quite a few women are nervous and weary of getting into cars driven by men. The service may also appeal to those whose religious beliefs forbid them to travel with unrelated men. Each driver wears a pink pashmina. Men who ask for a ride will be directed to another car service. Similar services thrive in India, South Africa and several Middle Eastern cities. Japan has had women-only railway carriages on and off since 1912. Known as hana densha (flower trains), they offer shelter from the gropers who make rush hour in Tokyo so disagreeable. But SheTaxis faces two speed bumps. One is practical. Demand has been so great that the firm has had to decelerate its launch until it can recruit 500 drivers. The other obstacle is legal. By employing only female drivers, SheTaxis is obviously discriminating against men. Since anti-discrimination law is not always applied with common sense, that may be illegal. And there is no shortage of potential litigants. Yellow cabbies are furious at the growth of online taxi firms such as Uber. "It"s not hard to imagine a guy ... filing suit," says Sylvia Law of New York University Law School. "SheTaxis" defence would probably be that its drivers are all independent contractors." Because the firm caters only to women, it is discriminating against male customers, too. Is that legal? Angela Cornell of Cornell Law School thinks there could be a loophole. New York"s Human Rights Commission could make an exemption on the ground that SheTaxi offers a service that is in the public interest: women feel safer not getting into cars with strange men. Women-only colleges are allowed, so why not women-only cabs? The snag is that some men may also feel safer getting into cabs with female drivers. A study in 2010 found that 80% of crashes in New York City that kill or seriously injure pedestrians involve male drivers. Women drivers are simply better.

Mark your answers on ANSWER SHEET 1. {{B}}Text 1{{/B}} When, in the age of automation, man searches for a worker to do the tedious, unpleasant jobs that are more or less impossible to mechanize, he may very profitably consider the ape. If we tackled the problem of breeding for brains with as much 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, which is 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, although 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 egregious specimens of Home 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 On 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 given up by mankind, to its great mental and physical advantage. What is more, one of the problems which has annoyed so many fictional Utopias would be avoided: There would be none of the degradingly 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, but the second would be a biological triumph which could benefit both men and animals.{{B}}Notes:{{/B}} surrealistic 超现实的。primate 灵长类动物。 gorilla 大猩猩。 baboon 狒狒。chore 杂活。 care to do sth.

单选题Until about four decades ago, crop yields in agricultural systems depended on (1) resources, recycling organic matter, built-in biological control mechanisms and rainfall patterns. Agricultural yields were (2) but stable. Production was (3) by growing more than one crop or variety in space and time in a field as insurance against pest (4) or severe weather. Inputs of nitrogen were (5) by rotating major field crops with legumes. In turn, rotations suppressed insects, weeds and diseases by effectively (6) the life cycles of these pests. A typical corn belt farmer grew corn (7) with several crops including soybeans, and small grain production was intrinsic to maintain livestock. Most of the labor was done by the family with occasional hired help and no (8) equipment or services were purchased from off4arm sources. In these type of farming systems the link between agriculture and ecology was quite (9) and signs of environment degradation were seldom evident. But as agriculture modernization (10) the ecology-farming linkage was often broken as ecological principles were (11) .

单选题{{B}}Text 4{{/B}} Artificial hearts have long been the stuff of science fiction. In "Robocop", snazzy cardiac devices are made by Yamaha and Jensen, and in "Star Trek", Jean-Luc Picard, captain of the Enterprise, has one implanted in the year 2328. In the present day, however, their history has been more chequered. The first serious attempt to build one happened in the 1980s, when Jarvik-7, made by Robert Jarvik, a surgeon at the University of Utah, captured the world's attention. But Jarvik-7 was a complicated affair that needed to be connected' via tubes to machines outside the body. The patient could not go home, nor even turn around in bed. Various other designs have been tried since, but all were seen as temporary expedients intended to tide a patient over until the real thing became available from a human donor. That may be about to change. This week, America's Food and Drug Administration gave its approval to a new type of artificial heart made by Abiomed, a firm based near Boston. The agency granted a "humanitarian device exemption", a restricted form of approval that will allow doctors to implant the new device in people whose hearts are about to fail but who cannot, for reasons such as intolerance of the immunosuppressive drugs needed to stop rejection, receive a transplant. Such people have a life expectancy of less than a month, but a dozen similarly hopeless patients implanted with Abiomed's heart survived for about five months. Unlike Dr. Jarvik's device, this newfangled bundle of titanium and polyurethane alms to set the patient free. An electric motor revolving up to 10 000 times a minute pushes an incompressible fluid around the Abiomed heart, and that fluid, in turn, pushes the blood--first to the lungs to be oxygenated, and then around the body. Power is supplied by an electric current generated in a pack outside the body. This induces current in the motor inside the heart. All diagnostics are done remotely, using radio signals. There are no tubes or wires coming out of the patient. The charger is usually plugged into the mains, but if armed with a battery it can be carried around for hours in a vest or backpack, thus allowing the patient to roam freely. Most strikingly, the device's internal battery can last half an hour before it needs recharging. That allows someone time to take a shower or even go for a quick swim without having to wear the charger. Abiomed's chairman, Michael Minogue, does not claim that his firm's product will displace human transplants. Even so, the firm has big ambitions. It is already developing a new version that will be 30% smaller (meaning more women can use it) and will last for five years. That should be ready by 2008--320 years earlier than the writers of "Star Trek" predicted.
