All ’that fault-finding about lowering cholesterol(胆固醇) and eating less fat must finally be paying off. According to a study published in the New England Journal of Medicine, more Americans are eating a healthy diet now than 30 years ago. In fact, according to researchers from the University of North Carolina, just about the only people who ate right in the mid-1900s were poor black people, who simply couldn’t afford the steaks and high-protein meals that were then considered the most nutritious. According to survey data collected by the U. S. Department of Agriculture, more than 16% of poor black people in 1965 ate a healthy diet, compared with less than 5% of high-income whites.
And what constitutes a healthy diet Less than 30% of calories from fat. Five or more servings a day of fruits and vegetables. Six or more helpings of legumes (peas and beans) and cereals (谷类食物). Exactly the diet that rich health-conscious people started adopting in the U.S. in the 19

Don’t look now, but they’re all around you. They’re standing by the copy machine, hovering by the printer, answering the phone. Yes, they’re the overworked, underappreciated interns: young, eager and not always paid. And with just 20% of the graduating class of 2009 gainfully employed, according to the National Association of Colleges and Employers, there are more and more of them each day. It seems the importance of internships for securing full-time work has dramatically increased over the years.
Intern, previously used in the medical profession to define a person with a degree but without a license to practice, became a term for a physician in training following World War I, when medical school was no longer seen as preparation enough for practice.

(46) We’re all too familiar with the concept of technology as a double-edged sword, and wire less is no exception. In fact, the back edge of this rapier is sharp enough to draw blood. Yes, the idea of shedding wires and cables is exhilarating: we can go anywhere and still maintain intimate con tact with our work, our loved ones and our real-time sports scores. (47) But the same persistent connectedness may well lead us toward a future in which our cell phones tag and track us like FedEx packages, sometimes when we’re not aware.
To see how this might work, check out Worktrack, a product from a California "mobile services’’ company Aligo. The system is sold to employers who want to automate and verify digital time logs on their workers in the field. The first customers are in the heating and air-conditioning business.
