【Dictation】听写科学美国人

鼓励的话：

一个成熟的人，应有的评判标准，不是外界反应，而是自身的价值认同。

如果你看到这句话会欣欣然或悻悻然，那么还是没到火候吧。

年轻时，不屑于简单的事情的。做一阵子，没人关注，就想偷偷放弃了。我们才开始接触这个世界，想着功成名就，想着远方，想着伟大的事情。

最有用的道理都是已经背的滚瓜烂熟了的。但是却不会去做。

却是为何？

因为我们始终相信必然有什么我们不知道的道理可以拯救下半生。

但这个道理，你已经读过无数遍了的。

Streetlights DrawInsects at Ground Level

More insects, including many carnivores and scavengers, hang out understreetlights than between them, even during the day. Christopher Intagliatareports

May30, 2012 

You've probably seenclouds of insects swirling round a streetlamp at night. But something you maynot have noticed is that streetlights attract bugs to the ground below them,too—especially carnivorous bugs, like beetles. So says a study in the journal Biology Letters byresearchers at the University of Exeter. Thomas W. Davies, Jonathan Bennie andKevin J. Gaston,"Street lighting changes thecomposition of invertebrate communities"]

Theresearchers set up 28 traps in the grass below and between streetlamps in theEnglish town of Helston, in Cornwall. They collected captured insects at dawnand dusk over three days, and ended up with nearly 1,200 specimens. Turns out,more bugs hung out under the lights than between them. And that was true atnight and day—suggesting that streetlights permanently upped the value of thebuggy real estate below them.

Theresearchers also found greater numbers of predators and scavengers under thelamps—like ground beetles, harvestmen and ants—because it may be easier to huntfor prey with the help of a spotlight.

Withartificial lighting increasing globally at 6 percent a year, the authors saythere's a chance light pollution could shake up food webs in unforeseen ways.Call it a bug in the system.
