Dolphins communicate with one another using a complex set of whistles, screeches(尖叫), and clicks. These【B1】are produced in the upper nasal passages just beneath the blowhole(呼吸孔). In many dolphin species each individual produces a(n)【B2】signature whistle. The loudness of the whistling may【B3】the emotional state of the dolphin.
Some studies of dolphins in confinement suggest that dolphins【B4】understand some elements of human【B5】. These language studies are controversial, however. Critics【B6】that the studies only show that dolphins are excellent imitators and【B7】strong hearing skills, but【B8】these abilities do not necessarily mean【B9】.
Because dolphins【B10】on sound to communicate and find food, scientists are【B11】about the increase of underwater noise【B12】from ship motors, oil drilling and production, and undersea machinery.【B13】loud sounds are used to develop sonar【B14】to study the structure of the seafloor, survey fish populations, or probe for submarines in warfare activities. Scientists believe that the high【B15】of noise levels in some ocean areas may interfere with the【B16】of dolphin calls or the ability【B17】locate food. In particularly noisy areas, tissues associated with【B18】, sound production, and air intake may be injured.【B19】some cases, noise pollution can even【B20】dolphins.
选项
A、noises
B、signs
C、sounds
D、cries
答案
B
解析
文中第一句概括到“海豚是通过发出各种复杂的声音来进行交流,这些声音包括吹口哨声、尖叫声以及滴答声。”紧接着,下一句话就解释说“这些声音是从气孔下端的上鼻腔发出来的。”因此[B]sounds(声音)正确。 [A]noises“噪声”、[C]signs“标记”、[D]cries“喊声”均不合文意。
