(2019·陕西咸阳高三质检)Listening to fish is a good way to get to know them. Hundreds, if not thousands, of fish species make __1__.
Scientists launched an experiment to __2__ deepsea fishes. They handed the devices over to fishers, who __3__ them into an underwater valley more than 600 meters deep. Twentyfour hours later, the scientists took them back to the __4__ for a listen.
Those recordings proved the deep sea is anything but __5__. The scientists reported hearing a wealth of biological sounds. Sounds of whales, as well as dolphins __6__ in the recording. In addition, the researchers heard a variety of __7__ sounds. At least some of these came from fish.
Fishers have reported hearing fish sounds __8__ the sea for hundreds of years. Listening to fish in their home habitat can provide scientists with a lot of information without __9__ the animals. Sounds can __10__ where fish are living without catching them in nets.To know where fish spawn, for example, scientists often have to catch, kill or annoy fish in their __11__. A researcher who __12__ the sound of the mating call of a certain fish, on the other hand, can know just by listening __13__ that fish reproduces.

You can go almost anywhere, like local ponds, lakes and rivers, and be the first person to __20__ a fish sound, and the first person to describe it.”
