剑桥雅思11 Test1 Section4听力答案解析
对应原文：These hotspots are significant because they allow us to locate key areas for focusing efforts at conservation
对应原文：The main thing he’d expected to find was that they had very high concentrations of food
对应原文： But what he did find was that in all cases, the water at the surface of the ocean had relatively high temperatures
对应原文：However, this wasn’t enough on its own, because he also found that the water needed to have enough oxygen in it
对应原文：A couple of years later, in 2007, a researcher called Lisa Ballance, who was working in California, also started looking for ocean hotspots, but not for fish – what she was interested in was marine mammals, things like seals.
对应原文： One thing they found there which stunned other researchers was that there were large numbers of species which live below the ice
对应原文： because they’re so mobile, and then thirdly they calculate the rate at which the decline of the species is happening.
对应原文： but they want to increase this figure to 20,000. For each one they assess, they use the data they collect on that species to produce a map showing its distribution.
对应原文：In addition, to preserve species such as leatherback turtles, which live out in the high seas but have their nesting sites on the American coast, we need to create corridors for migration
答案解析：这道题同样采用语序颠倒的手法，将括号里的内容（e.g. for turtles）提前，同时将答案与corridors换位，不过因为它们仍然属于同一个短语，所以还是比较好回忆的。
对应原文：If these commercial fishing boats used equipment which was more selective, so that only the fish wanted for consumption were caught, this problem could be overcome.
