Honeybees play an interesting and important role in nature.蜜蜂在自然界中扮演着有趣而重要的角色。
In addition to making honey, honeybees help many plants reproduce. 除了制造蜂蜜，蜜蜂还帮助许多植物繁殖。
They do this by pollinating the plant, which means to transfer pollen.他们通过给植物授粉来完成这项工作，这意味着要转移花粉。
Pollination occurs when pollen is moved within a plant's flower or carried to another flower.授粉是指花粉在植物的花内移动或被带到另一朵花上。

Honey bees are social insects that live in colonies. 蜜蜂是群居的昆虫。
A bee colony consists of a queen bee, male drones and thousands of female worker bees. 蜂群由一只蜂王、雄蜂和数千只工蜂组成。
Each colony also contains eggs and immature bees in various stages of development.每个蜂群还包含卵和处于不同发育阶段的未成熟蜜蜂。
The number of bees within a colony depends on seasonal changes. 蜂群中蜜蜂的数量取决于季节的变化。
A colony's population increases during the warm seasons and decreases during colder seasons.一个蜂群的数量在温暖的季节增加，在寒冷的季节减少。
In recent years, many bee colonies have collapsed, or disappeared. 近年来，许多蜂群已经减少或消失。

Some beekeepers have reported losing 30 to 90 percent of their colonies. .一些养蜂人报告说他们失去了30%到90%的蜂群。
This loss of bee colonies can cause significant problems for farmers who depend on them to pollinate their crops. 蜜蜂群落的消失会给依赖蜜蜂授粉的农民带来严重的问题。
In some parts of the world a shortage of bees has increased the cost of renting bees by up to 20%在世界上的一些地方，蜜蜂的短缺使租用蜜蜂的费用增加了20%。

Other possible causes include infections from viruses, genetic factors, and malnutrition.其他可能的原因包括病毒感染、遗传因素和营养不良。
Changing weather patterns may also play a role as summers get hotter and winters get colder. 随着夏季越来越热，冬季越来越冷，天气模式的变化也可能对蜂群有一定的影响。
These changes in weather may weaken the bees, making it more difficult for them to fight infections.天气的这些变化可能会削弱蜜蜂的力量，使它们更难抵抗感染。
Whatever the cause of colony collapses, it's important to understand that many parts of our world are interdependent. 无论殖民地崩溃的原因是什么，重要的是要明白我们世界的许多地方是相互依存的
Changes that affect one species may have serious effects on other species. 影响一个物种的变化可能会对其他物种产生严重影响。
A change to our environment can start a chain of events that is difficult to predict.环境的变化会引发一连串难以预测的事件。
In any complex system such as the Earth's environment, small changes can have unforeseen consequences. 在地球环境等任何复杂系统中，微小的变化都可能产生无法预料的后果。
