问题     When buying a house, you must be sure to have it checked for termites(白蚁). A termite is much like an ant in its communal habits, although physically the two insects are distinct.
    Like those of ants,termite colonies consist of different classes,each with its own particular job. The most perfectly formed termites,both male and female,make up the reproductive class. They have eyes, hard body walls, and fully developed wings. A pair of reproductive termites founds the colony. When new reproductive termites develop, they leave to form another colony, they use their wings only this time and then break them off.
    The worker termites are small, blind, and wingless, with soft bodies. They make up the majority of the colony and do all the work. Soldiers are also wingless and blind but are larger than the workers and have maybe " large" heads and strong jaws and legs. They defend the colony and are cared for by the workers.
    The male and female of the reproductive class remain inside a closed in cell where the female lays thousands of eggs. The workers place the eggs in cells and care for them.

选项 A、One
B、Two
