单项选择题The absence of Y2K induced problems has been remarkable. There were no falling planes, no exploding power stations, no rogue missiles. Those horrors were always the stuff of myth. But so sparse were tales of disaster that journalists were driven to reporting on malfunctions in the breath-testing’ machines used on drunken motorists by the Hong Kong police. More problems may emerge in the coming weeks. Overall, though, Y2K has turned out to be Y20K:
One partial explanation is that the huge effort lavished(浪费) on bug-squashing has worked. The United States, according to a Commerce Department estimate, spent about 100 billion on the problem; the rest of the world probably spent about the same again. Those numbers are far smaller than some of the more exotic figures trailed a few years ago, but they are still substantial. Yet even the countries that had begun work late and done little-southern Europe, Russia, much of Asia-had a trouble free new year. So was the money wasted

1.单项选择题"Copy the ways of nature", we were told. Yes, copy Nature—for everything comes directly or indirectly from natural things. Often we have to put our knowledge to work, treating Nature’s materials so as to make them serve our purposes better. We could, certainly, take the skin from a dead animal and at once make a pair of shoes with it; but they wouldn’t be very good shoes. For our purpose it is better first to treat the skin with chemicals that turn it into leather.
Why is it necessary for us to treat Nature’s material

A. An animal’s skin is not really useful to us.
B. Our purposes can be better served.
C. Natural materials are limited.
D. It is difficult to copy natur
2.单项选择题The other, more publicly acceptable form of geo-engineering would focus on removing carbon from the atmosphere and storing it underground. Known as carbon capture and storage (CCS), this idea is behind today’s experimental clean-power plants, which are attracting lots of research and funding. But clean, coal plants will only reduce future emissions, which does not address the root of the problem. Among all the uncertainties that still surround climate change, one thing has become clear: the scary durability of carbon, which will hang in the air for a thousand years, continuing to warm the planet no matter how drastically future emissions are cut. So there is a growing urgency behind the geo-engineer’s dream: to change the climate by artificial means, either sucking the existing carbon out of the air or cooling the air with solar reflectors.
Why is carbon so scary according to the passage

A. It will contihue to warm the globe for many years.
B. It cannot be easily captured and stored.
C. Its emission will increase in the coming years.
D. It cannot be reflected back into the spac

6.单项选择题A municipal management plan for storm-water runoff is mandated by the Clean Water Act. Early this year, Urban Stormwater Management in the United States, a report commissioned by the Environmental Protection Agency (EPA), recommended a number of ways to manage runoff, including using structural devices, like the kind AbTech produces. Rink is hoping that his merchandise appeals to budget-strapped municipalities. "Compared with building new storm-water treatment plants or upgrading already existing facilities to handle runoff pollution, which would cost in the millions of dollars, our products are very affordable," he says. The federal stimulus bill could make them even more so.
AbTech products are
AbTech products are
A. structural devices.
B. the best solution to run off.
C. appealing to budget-strapped municipalities.
D. costly.
7.单项选择题Lunge cancer, hypertension, heart disease, birth defects—we are all too familiar with the danger of smoking. But add to that list a frightening new concern. Mental illness.

8.单项选择题How sleep helps us consolidate memories is still largely a mystery. A recent study from the University of Lǔbeck, in Germany, offers one clue. Subjects were given a list of 46 word pairs to memorize, just before sleep. Then when they reached the deepest stages of sleep, electrical currents were sent through electrodes on their heads to induce very slow brain waves. Such slow waves were induced at random in the brains of one group of subjects, but not another.
The next morning, the slow-wave group had better recall of the words. Other types of memory were not improved, and inducing the slow waves later in the night did not have the same effect. Why and how the slow waves improved memory is not yet understood, but they are thought to alter the strengths of chemical connections, or synapses, between specific pairs of nerve cells in the brain. Memories are "stored" in these synapses: changing the strength of the synapses increases the strength of the memories they store.
Slow waves functioned in the subjects’ brains in the experiment when

10.单项选择题The first generation of dot-corns burned through cash rapidly because they had to spend a lot of money building and running their businesses—marketing and advertising to get the word out, not to mention software, consultants, and programmers to run online systems and" analyze theresults. Thanks to Web 2.0, many of these costs have plummeted. Many of the basics are nowessentially free, which means a business built on the infrastructure laid down by the first two generations of Web companies can gain scale on a shoestring budget, all while giving away its products and services for free.
