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 in North America, a land already filled with wild bees—more than 4,000 kinds of them. Some of those kinds of wild bee are bumblebees (大黄蜂). Maybe bumblebees are our most famous wild bees, and they are similar to 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. Among these species, 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 flowering plant species 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.

解析
【分析】
本题为说明文阅读理解，共3道题，分别考查细节理解、词义指代和细节推断。解题思路：1. 第1题需定位第一段内容，逐一核对选项与原文表述；2. 第2题是词义指代题，需联系代词所在句的前文，找到指代的核心名词；3. 第3题需定位各选项对应的原文段落，判断选项是否与原文一致。
【解析】
1. 定位第一段：“We take care of them so that they can take care of us by helping many of our crops grow.” 可知美国的大量蜜蜂帮助作物生长。A项“all year round”与原文“every summer”不符；B项“bored with”无原文依据；C项“useless”与原文相悖，故选D。
2. 代词“they”所在句前文提到“Some of those kinds of wild bee are bumblebees (大黄蜂). Maybe bumblebees are our most famous wild bees, and they are similar to honeybees in many ways.” 可知“they”指代前文的bumblebees，即美国的大黄蜂，故选B。
3. 定位最后一段：“the survival of each partner depends on the other”，对应A项“Plants and animals depend on each other to survive”；B项“from North America”与原文“People from England brought the first honeybees to North America”不符；C项“Male wild bees”与原文“each female is a hard-working single mum”不符；D项“move their pollen on their own”与原文“More than 80% of flowering plant species depend on animals to move their pollen”不符，故选A。
