Even happy families have secrets that run with no statute of limitations. Twenty years after my mother died, I discovered she had kept a scrapbook. It was delivered to me inside an old chest of drawers left by my father, who survived her by 18 years. The drawers were stuffed with memories and junk: his legal papers, his beloved mandolin sheet music, his college yearbooks and, in among some old photographs, a battered, yellowing composition notebook -- a scrapbook kept by my mother for a short time in 1934. I was shocked.
My mother was a thrower-outer -- the scourge of packed closets, the emptier of overfilled drawers. I was a bringer-backer. We once clashed over my cherished tennis shoes, which she mistakenly took to the garbage simply because I was stuffing card- board in the soles to plug the holes. I had to rescue them twice.
Ours was a fundamental clash in human nature, surely as old as the species itself. Some of our hominid ancestors were gatherers who also

[单项选择]
Surprisingly, there is a relationship between sea salt and the making of rain drops. Most of the water droplets that make up clouds are formed around small, solid particles. In order to fall as rain, the cloud droplets have to increase in size. Clouds from which rain does not fall have droplets that are fairly uniform in size. Clouds that produce rain have some droplets that are much larger than others.
The production of rain depends on the presence of the large droplets that grow in size by coalescence (a fusing together). There is evidence to support the theory that a particle of sea salt serves as the nucleus (核，核心) or center, around which the larger droplets form. Most of the sea salt probably enters the atmosphere from, bubbles that form on the surface of the sea. When the bubbles break, a tiny, even microscopic, droplet of salt water is cast into the air. Once in the atmosphere, the microscopic piece of salt collects water vapor from the air. The water vapor then co
