| 第1题：以下各题基于以下题干： 以下是在一场关于“安乐死是否应合法化”的辩论中正反方辩手的发言： 正方：反方辩友反对“安乐死合法化”的根据主要是在什么条件下方可实施安乐死的标准不易掌握，这可能会给医疗事故甚至谋杀造成机会，使一些本来可以挽救的生命失去最后的机会。诚然，这样的风险是存在的。但是我们怎么能设想干任何事都排除所有风险呢 让我提一个问题，我们为什么不把法定的汽车时速限制为不超过自行车，这样汽车交通死亡事故发生率不是几乎可以下降到零吗 反方：对方辩友把安乐死和交通死亡事故做以上的类比是毫无意义的。因为不可能有人会做这样的交通立法。设想一下，如果汽车行驶得和自行车一样慢，那还要汽车干什么 对方辩友，你愿意我们的社会再回到没有汽车的时代吗 豁正方论证预设了以下哪项 Ⅰ．实施安乐死带来的收益比可能产生的风险损失总体上说要大。 Ⅱ．尽可能地延长病人的生命并不是医疗事业的绝对宗旨。 Ⅲ．总有一天医疗方面可以准确无误地把握何时方可实施安乐死的标准。A．仅Ⅰ。 B．仅Ⅱ。 C．仅Ⅲ。 D．仅Ⅰ和Ⅱ。 E．Ⅰ、Ⅱ和Ⅲ。 |

| 第7题：When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy. Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu. What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago. Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003. The sentence "After each rain shower, another Internet millionaire sprang up" (Paragraph 1) means ______. A、many people get rich quickly and easily with the NewEconomy B、it takes only the time between showers for someone to become boss C、Seattle’s development is sudden like rain showers D、Seattle has as many business millionaires as its rain showers |

| 第8题：Climate change is the greatest challenge facing humanity: drastic reduction of carbon emissions is vital if we are to avoid a catastrophe that devastates large parts of the worl D、Governments and businesses have been slow to act and individuals now need to take the lea D、 TheEarth can absorb no more than 3 tons of carbon dioxide emissions each year for every person on the planet if we are to keep temperature and rainfall change within tolerable limits. Yet from ears and holiday flights to household appliances and the food on our plates, Western consumer lifestyles leave each of us responsible for over 12 tons of carbon dioxide a year—four times what theEarth can handle. Individual action is essential if we want to avoid climate chaos. How to Live a Low-Carbon Life shows how easy it is to take responsibility, providing the first comprehensive, one-stop reference guide to calculating yourCO2 emissions and reducing them to a sustainable 3 tons a year. |
