Passage 1
The division of social insects
The first and second paragraph introduces akind of bee, according to the body type, but the general bee is especially bigexcept for the queen, and the other bees are almost the same. There is no obviousdifference. Many insects are divided by age. The third paragraph first said thewasps, which were divided according to their age, but they worked at the sameage at flexible, which was the same age of bees that could be responsible forthe job or the job. Then said bees, there is a relatively clear division ofage, the young bees are responsible for keeping bees. The old bees are incharge of going out. The fourth and fifth paragraph said scientists wanted toknow whether their division of labor would change, so they changed thestructure of a bee's age, and then found that older bees transferred their workto the young bees in their nest, and then turned out to work out of the nest,so that their division of labor was variable.
社交型昆虫的分工,第一段还是第二段介绍了一种蜂,依据体型分类,不过一般的蜂除了女王特别大别的蜂体型都差不多,没有显差异,很多昆虫是靠年龄来分工的。
第三段先说了黄蜂,它们是按年龄分的,不过他们在同一年龄阶段的工作比较 随意,就是同样年龄的蜂既可能负责这项工作也可能负责那项工作。然后说了蜜蜂,有比较明确的不同年龄层的分工,年轻蜜蜂专门负责养小蜜蜂,大点的蜜蜂负责外出什么的。
第四还是第五段说科学家想知道他们的分工会不会改变,所以他们改变了一种蜂的年龄层结构,然后发现年纪更大的老蜜蜂把巢内的工作让给年轻蜜蜂,然后马上转去巢外的工作了,所以说明他们的分工是可变的。
