The Navy wont reveal whether the dolphins and sea lions have effectively stopped terrorists attempting to do harm to the U.S.A key part of the training program is teaching these mammals how to stop potentially unfriendly swimmers. The program is also positioned to defend against swimmer terrorist attacks as well.In the digital age, it seems that there should be more advanced approaches to guard the Navys most expensive things. But according to Rothe, the program director, nothing in todays high-technology world can compete with these mammals biosonar abilities. “I hope that one day there is a robot or a UUV (un-manned underwater vehicle) that makes the mammal program out of date,” he said. “But right now this is the best thing out there.”1. The U.S. Marine Mammal Program trained marine mammals to _.A. stop dangerous swimmersB. catch 20 pounds of fish a dayC. destroy sea minesD. fire torpedoes2. The U.S. trained dolphins because they _.A. are cleverB. swim very fastC. have natural biosonar D. have good underwater eyesight3. What can we learn from the last paragraph?A. The trained dolphins are the best way of protection available to the U.S. Navy.B. There will be dolphin-like robots in the future according to Rothe.C. The mammal program will become useless soon.D. Rothe has no faith in todays high technology.4. Which of the following is TRUE according to the text?A. Many countries have trained sea animals for counter-terrorism.B. The Marine Mammal Program was a secret until the 1960s.C. The trained sea animals have already stopped some terrorists.D. The U.S. Navy has trained both dolphins and sea lions.【参考答案】习题操练1.Having been accepted v-ing形式的被动完成式2. being photographed 此题v-ing形式的被动
