Since the 1960s, the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers, 【C2】________(recover) inert torpedoes (鱼雷) and to test objects used in Naval exercises.

Not only do these trained marine mammals track and retrieve millions of dollars in U. S. military eguipment, they are also helping to save lives.
The Navy won ’ t disclose whether the dolphins and sea lions have effectively intercepted(拦截) terrorist 【C6】________(attempt)to do harm to any U. S. facilities.
" Either way, it serves as a deterrent (遏制的) effect. " says Christian Harris, operations supervisor for the program.
