美国有线新闻 CNN 阿根廷潜水艇失联 多方联合搜救（在线收听）

First story is about an international rescue effort at sea. The ARA San Juan is an Argentine submarine. It mysteriously disappeared last Wednesday as it was travelling from the southernmost tip of Argentina back to its home port in Mar de Plata, which is a couple of hundred miles south of Buenos Aires.

Argentina's government said that various military bases had received seven satellite calls that likely came from the San Juan on Saturday. But yesterday, a top Navy officer said that though the calls are being analyzed, officials don't have, quote, clear evidence they came from the San Juan.

The missing sub has 44 crew members aboard. Many of their relatives gathered for mass in a navy base yesterday to pray for the crew's safe return.

The San Juan is 213 feet long. It has one electric and four diesel engines. It had traveled through an area known for intense storm. In fact, heavy winds and waves were hampering the search effort last night. The U.S. and British navies are both helping in that search. Aircraft, ships, satellite information and a remote underwater vehicle were all involved.

According to the British Broadcasting Corporation, the Argentine Navy says San Juan has enough food, water, and oxygen to last for two weeks or more.
