美国12月份的贸易逆差增加了将近4%。正在恢复的美国经济导致对进口商品的需求上升。
美国的进口和出口都再创新高，但进口的增长超过了出口。
美国商务部星期五发布的报告说，12月份美国的贸易逆差增加到488亿美元。
2011年全年美国贸易赤字上升11.6%，达到5580亿美元，为2008年以来最大的贸易赤字。
美国对华贸易赤字2011年又创下近2960亿美元的新高。这个问题很可能成为美国更加关注的一个政治议题。
The U.S. trade deficit got nearly 4 percent worse in December as a reviving economy boosted demand for imported goods.
Both imports and exports hit record highs, but imports grew even more than the flow of goods exported from the United States.
Friday's report from the Commerce Department says the gap between what foreigners sell to U.S. buyers and what Americans sell overseas rose to $48.8 billion for the month.
For all of 2011, the trade deficit rose 11.6 percent to a total of $558 billion, the worst showing since 2008.
The trade gap with China hit a record-high of nearly $296 billion for the year, and is likely to focus more attention on this political issue in the United States.
