[填空题]
A. Not everyone in Chile is happy. Investors in the smaller companies whose mines have been closed in the safety clamp-down are particularly displeased. But as well as complying with safety standards, it is helpful if mining companies have the resources, technical and financial, to cope when accidents do happen, as they inevitably will. As BP has demonstrated, being a big, well-financed business is no guarantee of an impeccable safety record. But BP did have one thing going for it—deep pockets. It has met the estimated $10 billion cost of the clean up so far, without recourse to the taxpayer.
B. Like unhappy families, every corporate disaster is unhappy in its own way. Except the Chilean mining disaster, which appears to be that rare phenomenon—a corporate disaster with a happy ending.
C. Of course, some people make their own luck. Unlike Tony Hayward, who sailed his yacht in the Channel while BP spewed oil in the Gulf of Mexico, President Pinera didn&

[填空题]Men, these days, are embracing fatherhood with the round-the-clock involvement their partners have always dreamed of -- handing night feedings, packing lunches and bandaging knees. But unlike women, many find they’re negotiating their new roles with little support or information. "Men in my generation (aged 25 - 40) have a fear of becoming dads because we have no role models," says Jon Smith, a writer. They often find themselves excluded from mothers’ support networks, and are eyed warily (警觉地) on the playground.
The challenge is particularly evident in the work-place. There, men are still expected to be breadwinners climbing the corporate ladder; traditionally-minded bosses are often unsympathetic to family needs. In Denmark most new fathers only take two weeks of paternity leave ( 父亲的陪产假) -- even though they are allowed 34 days. As much as if not more so than women, fathers struggle to be taken seriously when they request flexible arrangements.
