Where Have All the Bees Gone Scientists who study insects have a real mystery on their hands. All across the country, honey bees are leaving their hives(蜂巢) and never returning. Researchers call this phenomenon colony-collapse(群体瘫痪) disorder. It is reposed that 25 to 40 percent of the honeybees in the US have vanished from their hives since last fall. So far, no one can explain why. Colony collapse is a serious concern because bees play an important role in the production of about one-third of the foods we eat. As they feed, honeybees spread pollen(花粉)from flower to flower. Without this process, a plant can’t produce seeds or fruits. Now, a group of scientists and beekeepers have teamed up to try to figure out what’s causing the alarming collapse of so many colonies. They h A. Honeybees are flying all across the country. B. Half of the honeybees in the US have died. C. Honeybees are leaving their hives and do not return. D. Honeybee hives are in disorder. [多项选择]生殖器结核的临床表现有（ ）
