英语听力：自然百科 大迁徙之繁衍生息 Need to Breed—10

 The nursery lies at the heart of a twitching¹, thriving structure, built almost entirely² of the aunts of themselves. Long legs stuck together with tussle³ cores. They are the scaffolding, bricks, and mortar⁴ of the nests. But they’ve been in one place for 3 weeks, ravaging⁵ the forest floor from miles in all directions. It's time to migrate。

 

In the darkness, they pour out of the nests, porters carrying the precious larvae⁶.

 

There are virtually all sisters, daughters of one queen. They will migrate about 330 feet each night, the equivalent in human terms of Marathon. Death and virtually blind, they nonetheless communicate brilliantly through touch and complicated chemical signals and now the message goes out to beeswax
