This island is very rich in nature resources, (having) not only oil and gas but also coal and water.
请问这里为什么填having 只知道是该填这个,但说不出原因

having是现在分词做状语,分析过程如下:先看整个句子有两个分句构成,前一个句子的主语是island,后面那个句子的主语也是island,所以后面的island 为避免重复可以省略,同时,island与have 之间是主动的关系,所以用了现在分词的形式。

相当于which has

having是分词,引出后面的分词短语做状语。

(having) not only oil and gas but also coal and water.
当句子的伴随状语。

V+ing的一个用法。
例如:I am scared, sitting on the floor.

having。。。 现在分词短语做定语,修饰前面整个句子。是定语从句which has ...的省略形式。如:
The river is clear, which has a lot of fish in it.
The river is clear, having a lot of fish in it.
