In the US, there are more than 50 billion honeybees flying around our farms and neighbourhoods every summer. We take care of them so that they can take care of us by helping many of our crops grow. But honeybees aren't the only bees in town.
People from England brought the first honeybees to North America in 1622. But those European honeybees arrived at a land that was already filled with wild bees—more than 4,000 kinds of them. Some of those wild bee kinds are bumblebees (大黄蜂). Maybe bumblebees are our most famous wild bees, and they are the same as honeybees in many ways. They live in groups and they are active all summer long. But most wild bees are quite different. Many of them live their lives alone. In these kinds, each female is a hard-working single mum who builds her own nest, usually in an underground cave, lays her own eggs, and works alone to feed her babies.
More than 80% of all plant kinds depend on animals to move their pollen (花粉) from flower to flower. This process, called pollination (授粉), makes it possible for these plants to produce seeds.
All kinds of animals play an important role in pollination: butterflies, moths, flies, ants, even birds and bats, but bees are the best pollinators out there.
Some of these relationships have developed over millions of years, and the survival of each partner depends on the other.

第2题：定位第二段划线词所在句，前文提到“bumblebees (大黄蜂). Maybe bumblebees are our most famous wild bees, and they are the same as honeybees in many ways”，可知they指代前文的bumblebees（大黄蜂），对应选项B，排除A、C、D，选B。
第3题：A选项对应最后一段“the survival of each partner depends on the other”，说明动植物相互依赖生存，正确；B选项与第二段“People from England brought the first honeybees to North America”不符；C选项与第二段“each female is a hard-working single mum”不符；D选项与第三段“More than 80% of all plant kinds depend on animals to move their pollen”不符，排除B、C、D，选A。
