Simone非谓语动词的形式如何变化，其中哪些变哪些不变?
的有关信息介绍如下：
这个问题其实很简单，你就记住三条就行，注意这三条顺序不能变。
1，看语法上的强制要求。
2，看非谓语动词与逻辑主语是主动还是被动。
3，看非谓语动词与句中谓语动词发生的先后顺序。
举例说明
He is said to go abroad.据说他要出国。相当于It is said that he will go abroad.
He is said to have gone abroad.据说他已经出国了，相当于It is said that he has gone abroad.
He is said to be put in jail.
据说他要被送进监狱。相当于It is said that he will be put in jail.
He is said to have been put in jail.
据说他已经被送进监狱了。相当于It is said that he has been put in jail.
首先，上述句型只能用不定式形式，据说…to do是不定式一般式，to be done不定式被动式，可以翻译成即将被，to have done不定式完成式，表示发生在谓语动词之前，to have been done是不定式完成被动式，既表示跟逻辑主语是被动关系，又表示发生在谓语动词之前。
Babies are fond of being patted.婴儿喜欢被拍着睡觉。这句话介词of后面要求用ing形式，不能用不定式，但是用主动形式doing不行，因为doing表示主动，这里表示被动，所以用ing的被动形式being done。
至于你说的having been done，是ing的完成被动式，既表示跟逻辑主语是被动关系，又表示发生在谓语动词之前。
Having been separated from the continent, Australia has many particular animals and plants.
由于澳大利亚与大陆分隔，因此有很多不同的动植物。(被动分开，先分开，再形成特定的动植物)。相当于
Because Australia had been separated from the continent，
会了没？
