The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops--speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship's skin, or a nudge could knock the station out of its orbit.
The light-beam radar, which operates at a frequency of trillions (百万兆) of cycles per second, could easily detect and measure the movement of a vehicle edging up to a satellite space station. A control system using so precise a signal as this would allow a huge vehicle to dock at a space station as lightly as a feather.
Laser-doppler radar ______. ()
A．measures the movements of a spaceship by means of light beam
B．makes use of microwaves
C．makes use of sound waves
D．Both A and B
People can make poor decisions when it comes to health--despite their best intentions. It's not easy abiding by wholesome choices (giving up French fries) when the consequences of not doing so (heart disease) seem so far in the future. Most people are bad at judging their health risks: smokers generally know cigarettes cause cancer, but they also tend to believe they're less likely than other smokers to get it. And as any snack-loving dieter can attest, people can be comically inept at predicting their future .behavior. You swear you will eat just one potato chip but don't stop until the bag is empty.
So, what does it take to motivate people to stick to the path set by their conscious brain？ How can good choices be made to seem more appealing than bad ones？ The problem stumps doctors, public-health officials and weight-loss experts, but one solution may spring from an unlikely source. Meet your new personal trainer: your boss.
American businesses have a particular interest in personal health, since worker illness costs them billions each year in insurance claims, sick days and high staff turnover. A 2008 survey of major US employers found that 64% consider their employees' poor health decisions a serious barrier to affordable insurance coverage. Now some companies are tackling the motivation problem head on, using tactics drawn from behavioral psychology to nudge their employees to get healthy.
"It's a bit paradoxical that employers need to provide incentives for people to improve their own health," says Michael Follick, a behavioral psychologist at Brown University and president of the consultancy Abacus Employer Health Solutions.
Paradoxical, maybe, but effective. Consider Amica Mutual Insurance, based in Rhode Island. Arnica seemed to be doing everything right: it boasts an on-site fitness center at its headquarters. It pays toward Weight Watchers and smoking-cessation help, gives gift cards to reward proper prenatal care and offers free flu shots each year. Still, in the mid-2000s, about 7% of the company's insured population, including roughly 3 100 employees and their dependents, had diabetes. "We manage risk. That's our core business," says Scott Boyd, Amica's director of compensation and benefits. But diabetes-related claims from Arnica employees had doubled in four years. "We thought, OK," Boyd says now, "we have to manage these high-risk groups a little better. "
In the first paragraph, we can infer that the Americans ______.
A．vow to diet in the new year
B．fear to lose weight
C．have poor decision in keeping healthy diet
D．succeed in losing weight

India has about a billion people and a dozen major languages of its own. One language, and only one, is understood-by the elite-across the country: that of the foreigners who ruled India for less than 200 years and left 52 years ago.
Today, India. Tomorrow, unofficially, the world. That is well under way; at first, because the British not only built global empire but also it was settled by America, and now because the world (and notably America) has acquired its first truly global—and interactive—medium, the Internet.
It is estimated that some 350 million people speak English as their first language. Maybe 250-350 million do or can use it as a second language; in excolonial countries, notably, or in English—majority ones, like 30 million recently immigrants to the United States, or Canada's 6 million francophone Quebeckers. And elsewhere？ The guess is 100 million—1 billion depending how you define "can". Let us be hold: in all, 20-25% of earth's 6 billion people can use English; not the English of England, let alone of Dr. Johnson, but English.
That number is soaring as each year brings new pupils to school and carries of monolingual oldies—and now as the Internet spreads. And the process is self-reinforcing. As business spreads across frontiers, the company that wants to move its executives around, and to promote the best of them, regardless of nationality, encourages the uses of English. So the executive who wants to be in the frame, or' to move to another employer, learns to use it. English has long dominated learned journals: German, Russian or French (depending on the field) may be useful to their expert readers, but English is essential. So, if you want your own work published—and widely read by your peers—then English is the language of choice.
The growth of the cinema, and still more so of television, has spread the dominant language. Foreign movies or sitcoms may be dubbed into major languages, but for smaller audiences they are usually subtitled. Result: a Dutch or Danish or even Arab family has an audio-visual learning aid in its living-room, and usually the language spoken on-screen is English.
The birth of the computer and its American operating systems gave English a nudge ahead: that of the Internet has given it a huge push. Any web-linked household today has a library of information available at the click of a mouse. And, unlike the books on its own shelves or in the public library, maybe four-fifths is written in English. That proportion may lessen, as more non-English sites spring up. But English will surely dominate.
The author cites the example of India to show ______.
A．the backwardness of its own language
B．the importance of learning English
C．the widespread of English language
D．the great influence of the British empire
