农资店还是两间房,一间堆满肥料,一包摞一包;一间摆着种子农药,一层叠一层,似乎一切照旧。

Airplane designers have done their best to minimize the pain. Since the nineteen-thirties, cabins have evolved from wicker chairs in bare metal tubes to mood-lit cocoons full of curved surfaces. The air has been pressurized so that pilots can fly up to smoother skies. The service carts have been lightened with composites and braced with built-in brakes and stay-closed drawers. Should the plane suddenly drop, the passenger seats can bear a force of sixteen g’s; the jump seats have harnesses to hold down the crew. Should a fire break out, the walls, seat backs, and tray tables are made with self-extinguishing polymers that won’t give off toxic fumes. Floor lights will guide the passengers down darkened aisles, to evacuation slides that inflate and unfurl to the land or water below.
