describes a boatload of colonial american soldiers making their way to attack english the day after christmas in 1776.“most people think these other guys in the boat are rowing, but they are actually pushing the ice away，”says curry, tapping his finger on the painting.sure enough, the lead sailor is breaking the frozen river with his boot.“i grew up in the philadelphia.the place in this painting is 30 minutes away by car.i can tell you, this kind of thing just doesnt happen anymore.”but it may again soon.and icechoked scenes may also return to europe.the 16thcentury painter pieters works, including the 1565 masterpiece “hunters in the snow”，make the nowtemperate european landscapes look more like lapland.such frigid settings were commonplace during a period dating roughly from 1300 to 1850 because much of north america and europe was in the pain of a little ice age.and now there is increasing evidence that the cold could return.a growing number of scientists believe conditions are right for another lasted cooldown, or small ice age.while no one is predicting an ice sheet like the one that covered the northern hemisphere with glaciers about 12，000 years ago, the next cooling trend could drop average temperatures 5 degrees over much of the united states and 10 degrees in the northeast, northern europe, and northern asia.political changes since the last ice age could make survival far more difficult for the worlds poor.during previous cooling periods, these people simply picked up and moved south, but that doesnt work in the modem world, of closed borders.“to the extent the climate change may cause rapid and extensive changes of fortune for those who live off the land, the inability to migrate may remove one of the major safety homelands for pitiful people，”says the report.【语篇解读】通过本文我们知道，一个新的冰河时代即将开始。1the writer uses paintings in the first paragraph to say a. impossible future climate changebclimate change of the last two centuriescthe river
