[单项选择]In spite of rising concern in the Northeast and Canada, Administration spokesmen have repeatedly insisted that nothing could really be done about acid rain and the industry-produced sulfur emissions until all the scientific facts were in. Suddenly last week, however, facts came raining down, in effect making further scientific debate on what mainly causes the problem all but irrelevant.
What brought about the downpour was a study commissioned by Presidential Science Adviser. The spokesmen plainly called for remedial action even if some technical questions about acid rain were still unanswered. "If we take the conservative point of view that we must wait until the scientific knowledge is definitive," said the spokesman, "the accumulated deposition and damaged environment may reach the point of ’’irreversibility’’."

[单项选择]
The simple act of surrendering a telephone number to a store clerk may not seem harmful—so much so that many consumers do it with no questions asked. Yet that one action can set in motion a cascade of silent events, as that data point is acquired, analyzed, categorized, stored and sold over and over again. Future attacks on your privacy may come from anywhere, from anyone with money to purchase that phone number you surrendered. If you doubt the multiplier effect, consider your e-mail inbox. If it’s loaded with spam, it’s undoubtedly because at some point you unknowingly surrendered your e-mail to the wrong website.

[填空题]The Science of Lasting Happiness
The day I meet Sonja Lyubomirsky, she keeps getting calls from her Toyota, Prius dealer. When she finally picks up, she is excited by the news:she can buy the car she wants in two days. Lyubomirsky wonders if her enthusiasm might come across as materialism, but I understand that she is buying an experience as much as a possession. Two weeks later, in late January, the 40-year-old Lyubomirsky, who smiles often and seems to approach life with zest and good humor, reports that she is "totally loving the Prius". But will the feeling wear off soon after the new-car smell, or will it last, making a naturally happy person even more so
The Possibility of Lasting Happiness
An experimental psychologist investigating the possibility of lasting happiness, Lyubomirsky understands far better than most of us the folly of pinning our hopes on a new car--or on any good fortune that comes our way. We tend to adapt, quickly returning to ou
