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.
Program officials estimate that the sea lions in the Marine Mammal Program【C3】________(recover) millions of dollars of U. S. Naval torpedoes and instrumentation【C4】________(drop)on the sea floor.

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.
