律和特点才是制胜法宝。
Typically the queen honeybee is mother to all the bees in a
hive; after mating with several male drones from other colonies,
she lays fertilized eggs that develop into all-female worker bees
and lays unfertilized eggs that become all-male drones. When a
queen dies, workers often lay unfertilized eggs that hatch into
drones. Yet workers rarely reproduce while a queen reigns.
According to natural selection (natural selection:
n.[生]自然选择,物竞天择说) theory, a worker would enhance her
fitness—or ability to propagate her genes—by hatching her own
eggs in addition to or in place of the queen’s. But a typical
worker’s fitness would be diminished if other workers’ sons,
who have less genetic material in common with the worker,
supplanted the queen’s sons (the worker’s brothers).
Researchers, testing the hypothesis that workers usually
somehow block each other’s attempts to reproduce, put
unfertilized eggs laid by workers and by the queen into a hive.
Other workers quickly devoured the workers’ eggs while
leaving the queen’s eggs alone.
17. The author refers to the experiment described in lines
16-19 in order to
(A) explain how worker bees are prevented from mating with
drones
(B) explain how worker bees hatch and nurture the queen’s
young
(C) demonstrate the universality of natural selection
(D) show that worker bees are capable of thwarting each
other’s attempts to reproduce
(E) provide a model of daily life in a typical honeybee hive
18. The inner workings in a honeybee hive that regulate
reproduction, as they are described in the passage, are most
similar to which of the following types of human societies?
(A) A totalitarian society in which citizens’“policing” of
each other’s actions helps
