单选题Is nothing sacred? Even the idle weekend pastime of skimming stones on a lake has been taken apart and reduced to a mathematical formula. Everyone knows a stone bounces best on water if it's round and flat, and spun towards the water as fast as possible. Some enthusiasts even travel to international stone-skimming competitions, like world champion Jerdone Coleman-McGhee, who made a stone bounce 38 times on Blanco River, Texas, in 1992. Intuitively,a flat stone works best because a relatively large part of its surface strikes the water, so there's more bounce. Inspired by his eight-year-old son, physicist Lyderic Bocquet of Lyon University in France wanted to find out more. So he tinkered with some simple equations describing a stone bouncing on water in terms of its radius(半径) ,speed and spin, and taking account of gravity and the water's drag. The equations showed that the faster a spinning stone is travelling, the more times it will bounce. So no surprise there. To bounce at least once without sinking, Bocquet found the stone needs to be travelling at a minimum speed of about 1 kilometre per hour. And the equations also backed his hunch(直觉) that spin is important because it keeps the stone fairly flat from one bounce to the next. The spin has a gyroscopic(陀螺的) effect, preventing the stone from tipping and falling sideways into the water. To match the world record of 38 bounces using a 10-centimetre-wide stone, Bocquet predicts it would have to be travelling at about 40 kilometres per hour and spinning at 14 revolutions a second. He adds that drilling lots of small pits in the stone would probably help, by reducing water drag in the same way that dim pies on a golf ball reduce air drag. "Although I suppose that would be cheating," says Bocquet. He and his team at Lyon hope to design a motorized "catapult" that can throw stones onto a lake with a precise speed and spin, to test if the predictions stand up. Bocquet adds that he's probably just rediscovering a piece of history. British engineer Barnes Wallis must have done the same sort of maths and experiments when he was designing his famous bouncing bombs for the Dambusters squadron(中队) during the Second World War.

单选题{{B}}Passage Three{{/B}}
Most people would be impressed by the
high quality of medicine available to most Americans. There is a lot of
specialization, a great deal of attention to the individual, a vast amount of
advanced technical equipment, and intense effort not to make mistakes because of
the financial risk which doctors and hospitals must face in the courts if they
handle things badly. But the Americans are in a mess. The
problem is the way in which health care is organized and financed. Contrary to
public belief, it is not just a free competition system. To the private system
has been joined a large public system, because private care was simply not
looking after the less fortunate and the elderly. But even with
this huge public part of the system, which this year will eat up 84.5 billion
dollars—more than 10 percent of the U.S. budget—large numbers of Americans are
left out. These include about half the 11 million unemployed and those who fail
to meet the strict limits on income fixed by a government trying to make savings
where it can. The basic problem, however, is that there is no
central control over the health system. There is no limit to what doctors and
hospitals charge for their services, other than what the public is able to pay.
The number of doctors has shot up and prices have climbed. When faced with
toothache, a sick child, or a heart attack, all the unfortunate person concerned
can do is pay up. Two-thirds of the population are covered by
medical insurance. Doctors charge as much as they want knowing that the
insurance company will pay the bill. The medical profession has
as a result become America's new big businessmen. The average income of doctors
has now reached $100,000 a year. With such vast incomes the talk in the doctor's
surgery is as likely to be about the doctor's latest financial deal, as about
whether the minor operation he is recommending at several thousand dollars is
entirely necessary. The rising cost of medicine in the U.S.A. is
among the most worrying problem facing the country. In 1981 the country's health
cost climbed 15.9 percent—about twice as fast as prices in
general.

问答题美国财政部长亨利·保尔森昨天离开上海,结束了他对亚洲三国的访问。作为美国总统的首席经济政策顾问和最主要的经济事务发言人,保尔森昨天上午在上海期货交易所所发表的主题讲演被认为是布什政府对华经济政策的最新阐述。在昨天的讲演中,保尔森多次强调,中国的经济增长不仅不具有威胁性,而且对全球经济的增长有好处。他表示,美国欢迎中国发展并成为全球经济中的一员。
问答题尽管人为什么要睡觉这一头号题我们尚未弄清楚,但毫无疑问,人需要睡觉,其他动物也是如此。醒与睡的交替模式是与我们的习惯和感官密切相关的。动物靠视力寻找食物、栖息地和庇护,它们与人一样白天的大部分时间活动,晚上睡觉。为保持身体健康,一个人所需的睡眠时间因年龄不同而大不相同。学龄前儿童通常需要10~12个小时的睡眠时间,中小学生9~11个小时,成年人7~9个小时。成年人随着日益变老所需睡眠时间似乎也逐渐减少。睡眠时间也随种族不同而不同。据说,日本人,包括儿童和成年人,睡眠时间比欧洲人少。但这种不同也许是由于生活习惯而不是由于种族的原因造成的。

问答题There's no question that the big corporations are getting bigger and more powerful. Multinational corporations accounted for less than 20% of international trade in 1982.Today the figure is more than 25% and growing rapidly.International affiliates account for a fast-growing segment of production in economies that open up and welcome foreign investment.In Argentina,for instance,after the reforms of the early 1990s,multinationals went from 43% to almost 70% of the industrial production of the 200 largest firms.This phenomenon has created serious concerns over the role of smaller economic firms,of national businessmen and over the ultimate stability of the world economy.
