六．阅读理解
In a little-known part of the counter-terrorism (反恐怖主义) world, one of the most effective detection systems is a 600-pound animal that works for about 20 pounds of fish a day.
Since the 1960s, the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers, and to recover worn-
-out torpedoes (鱼雷) and testing objects used in naval (海军的) exercises.
The U.S. Navy kept its Marine Mammal Program a secret until the 1990s, and this spring CNN became one of the first members of the media to witness firsthand how the program works.
The program trains about 75 Pacific bottlenose dolphins, with natural biosonar (生物声纳) that tracks better than any manmade device; and 35 California sea lions, with very good underwater eyesight.
Not only do these trained marine mammals track and save millions of dollars in U.S. military equipment, they are also helping to save lives. T he Navy won’t 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 Navy’s most expensive things. But according to Rothe, the program director, nothing in today’s high-techno logy 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 “I hope that one day there is a robot or a UUV (un-manned underwater vehicle) that makes the mammal program out of date,” he said.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 swimmers
B. catch 20 pounds of fish a day
C. destroy sea mines
D. fire torpedoes
2. The U.S. trained dolphins because they ______.
A. are clever
B. swim very fast
C. have natural biosonar
D. have good underwater eyesight
3. 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 today’s 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.
