句子成分分析
By the beginning of the 20th century, with both the refinement of the internal-combustion engine and the realisation by the navies of the great powers that their ships could go farther and faster with boilers fuelled by oil rather than coal, reliable access to oil in times of war became a major security concern.
1.by the navies of the great powers 这里的介词短语是后置定语吗？
2.that是同位语从句解释说明the great powers吗？
3.fuelled by oil非谓语动词做后置定语修饰boilers？
4.reliable access to oil在这里是什么成分？

1和2 你先看一下这个句子：The navies of the great powers realized that their ships could go farther and faster with boilers fueled by oil rather than coal. 这是一个主谓宾结构的句子，that从句为realized的宾语从句。我们可以把这个句子改为一个名词性结构，即用realize的同源名词realization作中心词，原句的主语用by介词短语引出，语法上是定语，但语义上是realization这个动作的施事者。that从句置于by介词短语之后，语法上是realization的同位语，但语义上是动词realized的宾语。于是就得到了the realization by the navies of the great powers that their ships could go farther and faster with boilers fueled by oil rather than coal这个名词词组。
3 是的。
4 reliable access to oil in times of war是句子的主语，后面的became是谓语动词。
