美原油跌破30美元关口

U.S. oil futures rose on Wednesday for the first time in eight days, pulling further back from the widely watched $30-per-barrel level breached the previous session, after industry data showed crude stocks unexpectedly fell last week.

上周原油库存大减，美原油上一交易日跌破30美元大关，周三，美原油期货8天首反弹，每桶重回30美元。

U.S. West Texas Intermediate crude was up 30 cents at $30.74 a barrel.

西德州中质原油报收于每桶30.74美元，涨幅30美分。

On Tuesday, it fell 97 cents to close at $30.44 a barrel, after touching a low of $29.93, which was last seen in December 2003.

周二，下跌97美分，报收于每桶30.44美元，盘中一度触及每桶29.93美分，创下自2003年12月以来最低收盘价。

The $30 mark is both a psychological and financial threshold and, in recent days, traders have poured money into $30 put options for expiration in February and March.

30美元大关既是心理界限，也是金融关口，近日，因2,3月份原油期货合约到期，投资者纷纷抛售。
