???? 據道瓊斯2月20日消息，周五，美國天然氣期貨價格略微收跌0.4%，至3.069美元/百萬英熱單位，但是本周上漲5.4%，并且是連續第四周周線上漲。本周天然氣價格上漲的趨勢主要是由于一場冬季風暴突然襲擊了德克薩斯州，迫使美國約20%的天然氣生產中斷。但在過去兩個交易日中，天然氣價格已經開始回落，部分原因是人們擔心液化天然氣出口也受到冬季暴風雪的影響，另一個原因是人們擔心如此寒冷的2月份可能導致早春和暖春的突然到來，這可能會拖累需求。

????Natural Gas Notches 4th Straight Weekly Rise

????Natural gas prices finish a slight 0.4% lower at $3.069/mmBtu, but end with a 5.4% weekly increase -- the fourth straight weekly rise for the commodity. The rising trend for natural gas this week was largely due to a brutally-cold winter storm that took Texas by surprise and forced some 20% of US gas production offline. But gas prices have begun to retreat the past two sessions, partly on concerns that LNG exports are also being hurt by the winter storms, but also on worries that such a cold February might lead to the sudden arrival of an early and warm spring that could hurt demand.
