1.The history of clinical nutrition or the study of the relationship between health and how the body takes in and utilizes food substances,can be divided into four distinct eras how引导的是什么从句?
The history of clinical nutrition or the study of the relationship between health and how the body takes in and utilizes food substances, can be divided into four distinct eras.
全句分析意见：
全句主从复合句，从句部分是how引出的宾语从句，做第一个“of”的介词宾语从句；
-
全句语法结构如下：
The history 【主句主语】of 【of 后面有三个介词宾语】clinical nutrition 【of后面的第一个介词宾语】or the study of the relationship between health 【of 后面的第二个介词宾语】and how the body （how 从句里的主语）takes in （how 从句里的第一个谓语动词）and utilizes （how 从句的第二个谓语动词）food substances（how 从句里的宾语）【of 后面的第三个介词宾语，how在这里做of介词宾语从句】, can be divided into four distinct eras【主句的谓语动词和宾语】.

how 可以引导五类从句，分别是：
a. 主语从句 - How we do this job has not been decided yet. ；
b.宾语从句 - The important thing we are going do it should be decided. 还有做介词的宾语，例如你的原句（不另外举例了）；
c.表语从句 - I don't know how she has come.；
d.状语从句 - I know nothing about this river, neither how long, how wide nor how deep it is. No matter how expensive it may be, I”ll take it.；和
e.定语从句 - The way how he looks at the problem is wrong.
（The history of clinical nutrition or the study 主语）（of the relationship between health and how the body takes in and utilizes food substances定语，修饰the study ）, （can be divided谓语）（ into four distinct eras补语）
how the body takes in and utilizes food substances可看成介词of的宾语从句
第一个不加be。
第二个，修饰的是The radio and the book ，因为后边用的是are；第二问还是一样，n the shelf修饰的是flower and cup，要不然就是带着半句废话的话，人类的思维不是这样的。
第三句话一看就是中国英语，老外这么说话会被人问：你为什么放弃治疗？but是连词，其他不是。
第四个问题感觉应该是singles吧？单身的。总之看不到整句话不迷噶比什么意思。
第五问： on their own ground修饰the project 。
这里的how引导主语从句，给你几个例子你应该就会更了解how了
How 可引导如下从句：1.主语从句－－How he come here is a mystery.
2.宾语从句－－I don't know how we can get there so soon.
3.表语从句－－It was how we learned so much in so short a period.
4.状语从句－－No matter how he begged , the boss didn't care.
