我画的og11-1的逻辑简图，希望大家帮忙指正一下

刚开始做阅读，一上来就碰到og11-1这样的说明文，所以逻辑简图画的满痛苦，也不知道抓出的是不是重点。贴出来，请大家帮忙指正一下。

1）提出写作对象N（naked mole rat）：V（verterbrate）与E（eusocial iinsects）不相似。however,V中的N与E相似。

2）N与E相似处：N，like E,queen.

3）N与E不同处：E. N，on the other hand. Smaller nonbreeding...Larger nonbreeding... Jarvis' work.

4)N与大部分V区别：Coorperative breeding in V,but unlike N,most V...rather than.division of labor,less...than...,colony size,mating,whereas.

另外，og解释中说From its opening sentence, this passage depends on a comparison between eusocial insect societies and naked mole rat colonies. 但文中第四段并没有讲comparison between eusocial insect societies and naked mole rat colonies，而且我觉得他比较N和E只是为了说明N的特点，主题应该是说明N，而不是比较N和E。主题句However, such a vertebrate society may exist among underground colonies of the highly social rodent Heterocephalus
                        glaber, the naked mole rat.也是主要说N阿。为什么og说主题是comparison呢？请大家指教
