But 28-year old Hisako Koyama saw these blackouts as opportunities.

28 小山久子却将灯火管制视为难得机会。

Widespread " brownouts" across the country in 1998 made power companies scramble to build new gas-fired stations, only for these to come on line in time for the 2001 recession.

1998年全大面积" 灯火管制" 使得很多电力公司争先恐修建新燃气发电厂，等这些发电厂竣工投产时，却正好赶上2001年经济衰退。

To  prevent aerial bombardment, American cities practiced blackout exercises, which required  cities to dim or turn off most of their lights to minimize the likelihood of being targeted.

为了防止空中轰炸， 市举行了灯火管制演习，要求市调暗或关闭大部分灯光， 以最大限度地降低遭到袭击可能性。
