本文选自雅思听力Section 3，难度一般Summary:本部分是昆虫教授向学生讲解亚洲蜜蜂是如何通过自身携带的寄生虫来影响澳洲蜜蜂的HINTSRainbow Bee Eater全文听写，英式拼法订阅节目更方便How will you know if Asian bees have entered Australia?
We're looking at the diet of the bird called the Rainbow Bee Eater. The Bee Eater doesn't care what it eats, as long as they're insects. But the interesting thing about this bird is that we are able to analyse exactly what it eats and that's really helpful if we're looking for introduced insects.
Because insects have their skeletons outside their bodies, so the Bee Eaters digest the meat from the inside. Then they bring up all the indigestible bits of skeleton and, of course, the wings in a pellet, a small ball of waste material which they cough up.
That sounds a bit unpleasant. So, how do you go about it?
In the field we track down the Bee Eaters and find their favourite feeding spots, you know, the places where the birds usually feed. It's here that we can find the pellets. We collect them up and take them back to the laboratory to examine the contents.编辑点评：本文选自雅思听力Section 3，难度一般Summary:本部分是昆虫教授向学生讲解亚洲蜜蜂是如何通过自身携带的寄生虫来影响澳洲蜜蜂的HINTSRainbow Bee Eater全文听写，英式拼法订阅节目更方便How will you know if A...
