Mighty Flighty
A fly can do one thing extremely well: fly.
(86) Recently a team of British scientists declared that the common housefly is the most talented aerodynamicist on the planet, superior to any bird, bat, or bee. A housefly can make six turns a second; hover; fly straight up, down, or backward; do somersaults; land on the ceiling; and perform various other show-off maneuvers. And it has a brain smaller than a sesame seed.
Michael Dickinson, who studies fly flight in his lab at Caltech, says the housefly isn’t actually the best flier. "Hoverflies are the be-all and end-all," he says.
(87) They can hover in one spot, hurtle through the air to another location, and then race back to their original hovering point pre cisely. Scientists, engineers, and military researchers want to know how creatures with such small brains can do that. Maybe they could reverse-engineer a fly to make a

[单项选择]The most damning thing that can be said about the world’s best-endowed and richest country is that it is not only not the leader in health status, but that it is so low in the ranks of the nations. The United States ranks 18th among nations of the world in male life expectancy at birth, 9th in female life expectancy at birth, and 12th in infant mortality. More importantly, huge variations are evident in health status in the United States from one place to the next and from one group to the next.
The forces that affect health can be divided into four groupings that lend themselves to analysis of all health problems. Clearly the largest group of forces resides in the person’s environment. Behavior, in part derived from experiences with the environment, is the next greatest force affecting health. Medical care services, treated as separate from other environmental factors because of the special interest we have in them, make a modest contribution to health status. Finally, the contri
