possible to me【解析】考查thank sb. for doing sth.“(为某事)道谢”，故排除A、B项；又make it possible for sb.是固定用法，“使对某人来说成为可能”，故排除D项。【答案】C7Mr.Smiths giving his lessons _ makes his lessons lively and

is hard to track the blue whale，the oceans largest creature which has almost been killed off by commercial whaling and is now listed as an endangered species.Attaching radio equipment to it is difficult and visual sightings are too unreliable to give real insight into its behavior.So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds.This was possible because of the Navys formerly topsecret system of underwater listening equipment spanning(估量)the oceans.Tracking whales is but one example of an exciting new world just opening to civilian (民用的) scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deepsea volcanic eruption for the first time and that they plan similar studies.Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.The speed of sound in water is roughly one mile a secondslower than through land but faster than through air.What is most important，different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patients chest to a doctors ear.This focusing is the main reason that even relatively weak sounds in the ocean especially low frequency ones can often travel thousands of miles.1The passage is chiefly about _.Aan effort to protect an endangered marine speciesBthe civilian use of a military detection systemCthe exposure of a US.Navy topsecret weaponDa new way to look into the behavior of blue whales【解析】主旨大意题。根据短文第二、三段所表述的内容可知：军事探测系统开始进入民用。【答案】B2The underwater listening system was originally designed _.Ato mark and locate enemy shipsBto monitor deepsea volcanic eruptionsCto study the movement of ocean currentsDto replace t
