托福听力荟萃 40

Today I want to talk to you about _______ and their nests. You'll recall that biologists divide species of wasps¹ into two groups: _______ and social.

Solitary² wasps, as the name ______,do not live together with other wasps. In most species the male and female get together only to mate, and then the female does all the work of building the nest and providing food for the offspring by herself. Solitary wasps usually make nests in the ground and they separate the for individual offspring with bits of grass, stone, or mud, whatever is handy.

What about social wasps? They form a community and work together to build and maintain the nest. A nest begins in the spring when a fertile female, called the queen, builds the first few compartments³ of the nest and lays eggs. The first offspring are small females that cannot lay eggs. These females, called workers, then build a lot of new _______, and the queen lays more eggs. They also care for the new offspring and defend the nest with their stingers. By the way, only female wasps have stingers.

Most social wasps make nests of paper. The females produce the paper by chewing up plant fibers⁴ or old wood. They spread the paper in thin layers to make cells in which the queen lays her eggs. Most of you, I'm sure, have seen these nests suspended from trees. They may also be built underground in abandoned rodent⁵ burrows⁶.
