It is hard to track the blue whale, the ocean’s largest creature which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and 【S1】______ sightings are too unreliable to give real 【S2】______ into its behavior.
So biologists were delighted early this year when with the help of the Navy, they were able to 【S3】______ a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of under water listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly 【S4】______ its global network of underwater listening system built over the decades to track the ships of 【S5】______ enemies.
Earth scientists announced at a news conference recently that they had used the system for closely 【S6】______ a deep-sea volcanic eruption (爆发) for the first time.
The speed of sound in water is 【S7】______ one mile a second—slower than through land but faster than through air. What is most important, different 【S8】______ of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it 【S9】______ faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even 【S10】______ weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.
A) layers B) roughly C) observation D) monitoring
E) visual F) uncover G) discover H) carries
I) relatively J) visible K) insight L) examining
M) potential N) considerably O) track
【S10】
选项
答案
I
解析
从结构判断应选择一个副词,来修饰形容词weak。选项中relatively和considerably意思比较相近,但relatively意为“比较地,相对地”,而considerably是“非常,相当地”的意思。从上下文判断应选择relatively。这部分的意思是“……海洋中比较微弱的声音,尤其是低频率的声音也经常能传到数千英里之外”。
