单选题When men get sick, they act like babies, say women. But maybe the fairer sex should learn something useful from these guys—it could save their lives, say researchers at the University of Michigan. When women have a heart attack, they' re more likely to put off seeking help than the men, and after an attack, they' re less likely to take steps to improve their health. What' s the reason for the different responses? The results of a survey suggest that women are too tough; they think heart problem are simply not a big deal. When Steven Erickson and his colleagues asked 348 men and 142 women who had been admitted to the hospital for a heart attack about their symptoms and medication(用药情况), they found that even though the women had more symptoms and were taking more medicine they rated their disease as being no more severe than the men did.

单选题Passage Two Nearly four years ago, a web-based political movement set itself the modest task of "closing the gap between the world we have and the world most people everywhere want". Calling their group Avaaz, which means "voice" in several languages, the founders aimed to reproduce globally some of the success which their predecessors—like America's Moveon.org, and Australia's Getup! —had enjoyed in national political fields. By its own lights, the movement, using 14 languages and engaged in an astounding list of causes, has had some spectacular successes. Within the next few months, membership will top 6m. The number of individual actions taken is estimated at over 23m. Among the recent developments Avaaz claims to have influenced are a new anti-corruption law in Brazil; a move by Britain to create a marine-conservation zone in the Indian Ocean; and the spiking of a proposal to allow more hunting of whales. But is there any objective measure by which the reach of a global e-protest movement can be assessed? Sceptics use words like "clicktavism" to describe political action that demands nothing more of a protester than pressing a button, which may just imply curiosity; and it is rarely possible to prove beyond doubt that e-campaigning is a decisive factor in a political outcome. On the other hand, argues Ricken Patel, a co-founder of Avaaz, digital activism rarely ends with the click of a mouse. Avaaz's campaign against the death sentence for adultery imposed on an Iranian woman asks members to phone Iranian embassies (and provides numbers) ; members are also being urged to put pressure on the leaders of Brazil and Turkey to intercede with Iran. Avaaz is collecting funds for a campaign in the Brazilian and Turkish press, too. Avaaz's other demands range from the simple--close Guantanamo, because it plays into the hands of Osama bin Laden—to the very broad: fight climate change, avoid a clash of civilisations. Despite the risk of foggy signals, the variety of causes is also a strength, says Dave Karpf, an American analyst of the net; it allows the group to act as a hub, attracting members to one campaign and telling them about others. As Evgeny Morozov, a writer on the Internet points out, Avaaz has lost whatever monopoly it had over the creation of instant, cross-border lobbies; you can do that on Facebook. But the way Avaaz bunches unlikely causes together may be an asset in a world where campaigns, like race and class, can still segregate people, not reconcile them.

单选题Can the Internet help patients jump the line at the doctor's office? The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits" between doctors at three big local medical groups and about 6,000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees won't have to skip work to tend to minor ailments or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your doctor in your hometown can be a big chunk of time," says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies. Doctors aren't clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stifling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work. " In the pilot program, physicians will get $ 20 per online consultation, about what they get for a simple office visit. Doctors also fear they'll be swamped by rambling E-mails that tell everything but what's needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif-based start-up. Healinx's "Smart Symptom Wizard" questions patients and turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face-to-face visit. Can E-mail replace the doctor's office? Many conditions, such as persistent cough, require stethoscope to discover what's wrong and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor's groups in the pilot, believes the virtual doctor's visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet's record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healing", notes Michael Barrett, an analyst at Internet consulting firm Forester Research. If the "Web visits" succeed, expect some HMOs(Health Maintenance Organizations)to pay for online visits. If doctors, employers, and patients aren't satisfied, figure on one more E-health start-up to stand down.
