第272期：主餐一道：泛聽練習
以下段落是摘自新聞里的一些重要信息,并不是一個段落的聽寫。空內信息可在本新聞中全部找到,大家可以根據(jù)這些信息復述新聞。

And in California a persistent night time artic chill could _2_ the State's two billion dollar citrus industry as well as food supplies and prices. Daniel Karson reports from LA.
美國國家氣象局繪出了冬季天氣預警地圖，包括零下溫度以及擾亂百萬民眾生活的冰雪天氣。加州地區(qū)遭遇北極冷空氣，寒冷的夜晚還在持續(xù)，這可能會對加州價值20億美元的柑橘產業(yè)造成威脅，同時加州的食品供應和食品價格也將受到影響。丹尼爾·卡爾森將從洛杉磯帶來詳細報道。
Cold snaps are normal this time of year, but the National Weather Service says this steep freeze _3_, it's specially troubling for California's nearly 4000 artic growers most of whom are farmers, they turning on warm machines to circulate warm air and soak in grows with water to raise the ground temperature. Farmers are about eight weeks into the season and 85% of the harvest has yet to be plucked, there is still a billion dollars worth of oranges, lemons, tangerine and grapefruits still _4_ on the trees, but next few nights could change all that. Seven years ago they lost more than half of their crops to freeze. By the middle of next week the arctic airs _5_ to move out and temperature will warm up. For NPR News, I am Daniel Karson in LA.
每年這個時間遭遇寒流是很正常的事情，但是國家氣象局表示，這次突然襲來的嚴寒很不尋常，尤其是對加州近4000名柑橘種植者來說，他們大部分人都是農民，他們要打開取暖的機器讓暖空氣流通，增加水分，以提高地面溫度。目前進入收獲季已經有8周的時間了，而85%的果實還沒有采摘，目前仍有價值10億美元的橘子、檸檬、柑橘還有葡萄掛在樹上，而接下來幾個晚上可能會改變一切。七年前，因為嚴寒他們損失了近1半的收成。北極冷空氣將于下周周中時移出加州，天氣將變暖。NPR新聞，丹尼爾·卡爾森洛杉磯報道。
