您好
Not only can walking fish live out of water,but they can also travel short distances over land.
not only... but(also) not only 于句子开头要用倒装，but后面的句子不用倒装
2. Scientists do not know why dinosaurs became extinct, but sometheories postulate that changers in geography, climate, and sea levels were responsible.
do not know +宾语从句why引导的
but表示转折，连接两个句子
postulate 是谓语+that引导的宾语从句
3. The science of horticulture, 主语1
in which the primary concerns aremaximum yield 非限制性定语从句，先行词是horticulture
and superior quality, utilizes information 主语2 主语3
derived from othersciences. 谓语+介宾短语
4. Snow aids farmers 主谓宾
by keeping heart 介宾短语
in the lowerground levels, 地点状语
thereby 副词
saving the seeds from freezing. 动名词，伴随动作
5. Even though 转折连词
the precise qualities 主语
of hero in literary words 介宾短语 表示出处
may vary 复合动词做谓语
over time, 时间状语
the basic exemplary function of the hero 第二个句子的主语
seems 系动词
to remain constant. 动词不定式做表语
能更加详细吗？分别罗列出主谓宾定状补？谢谢。
追答1. Not only can （walking fish主语） （live 谓语）（out of water状语）,but （they主语） （can also travel谓语） （short distances宾语） （over land 状语）..
下面的以此类推。
