哪位大神帮我分析一下下面三个句子的结构!以及主谓宾,从句等.急、急、急!
Ifwe repeat the experiment with various materials ,we find that all objects fall into one of just two groups-thoselike the plastic rod rubbed with fur and those like the glass rod rubbed with silk.
In Coulomb’s experiment ,the charged spheres were much smaller than the distance between them so that thechargescould be treated as point charges.
For example ,beginning with charge on eachsphere ,he could reduce the charge to /2 bytemporarily grounding one sphere to discharge it andthen placing the two spheres in contact.

先说第一句：
If we repeat the experiment with various materials ,we find that all objects fall into one of just two groups-thoselike the plastic rod rubbed with fur and those like the glass rod rubbed with silk.
其实是什么从句什么的,就算说了也记不住,还不如理解的简单一点.
主要分析后面半句,we find that all objects fall into one of just two groups-thoselike the plastic rod rubbed with fur and those like the glass rod rubbed with silk.
主语：we
谓语：find
后面就是宾语从句了,宾语是all objects ,这些objects是fall into one of just two groups的,也就是说objects后面的fall into one of just two group是它的定语.
那么后面thoselike the plastic rod rubbed with fur and those like the glass rod rubbed with silk.这句话就是形容上面这个现象像什么什么和像什么什么,是另外一句了相当于.
第二句：
In Coulomb’s experiment ,the charged spheres were much smaller than the distance between them so that the charges could be treated as point charges.
这句话前面in什么什么,只是状语成分了.
主语：the charged spheres
谓语：be动词were做谓语
后面much smaller than the distance,这个distance是between them的.
后面so that 就是一个状语从句,从句记不住没关系,想成中文就很好理解,为了什么,前面那么多什么什么的为了干吗干吗,就是这样理解,为了什么呢,就是the charges could be treated as point charges.为了让charges可以为对待成主要的charges.
第三句：
For example ,beginning with charge on each sphere ,he could reduce the charge to /2 by temporarily grounding one sphere to discharge it and then placing the two spheres in contact.
这句那个2有点奇怪,估计打错了,不过没事.
这句For example不重要,beginning with charge on each sphere先不管,先分析后面的句子.
he could reduce the charge to /2 by temporarily grounding one sphere to discharge it and then placing the two spheres in contact.
主语：he
谓语：could
宾语：reduce the charge
后面跟了个to,就是为了干吗,为了什么什么,to /2‘
然后是by 通过什么,都是从句,通过grounding one sphere to discharge it and then placing the two spheres in contact.,都是by后面的,temporarily是副词,修饰grounding
也就是他可以降低什么什么通过什么什么为了干吗干吗.
然后就是前面的,beginning with charge on each sphere.这个也是个状语成分,就是开始什么的时候,他干吗干吗了.
基本上我分析句子就是这样,把一个句子一点点解剖开来分析,也希望你能理解,不懂可以再问.
