关于动名词的一个用法不解

亲亲号

# F% s! P# @8 F2 s" \
6 \: y0 U. ^" y$ U" ?$ b动名词的形式有doing 和 having done，后者是完成式，用于发生在句子谓语动作之前的动作，
如That young man still denies having started the fire behind the store.
但由于start是短暂动词，这里如果只用现在分词的一般式也是正确的把？而且意义没有太大区别？
That young man still denies starting the fire behind the store.
* C7 t" w; a2 N  i2 \7 n
类似还有这些句子
1 i1 S! Z, d% RI repented shooting/having shot the bird
* a6 K# |0 s+ Y1 g6 F0 Y' gThe man in the corner confessed to telling/having told a lie to the manager of the company.
7 i' N4 ?/ q/ {The student denied cheating/having cheated on the exam.

; y, ]8 r4 X' _: M请问这样理解是正确的么？

个人认为，楼主这些例子里面的 having+pp 形式是从句简化导致的变形。

即：That young man still denies having started the fire behind the store. 这句话跟动名词一点关系都没有。

# m; k/ @6 ~) ?6 T9 Q/ C; i, s我觉得上句应是下句的简化：
" f* b% |! j  M' Z: _2 f5 qThat young man still denies that he had started the fire behind the store.

# v+ |3 n# k" _; _1 M同理：
0 z( g3 T" p( K% y8 z$ ]I repented that I had shot the bird
简化为
I repented having shot the bird

两个句子都没问题，意思是一样的。having started 强调 放火发生在否认之前。
& s' S' l9 N# J5 v& N* y如果没有 supporting references 的话，推荐用 That young man still denies starting the fire behind the store. 更符合外国人习惯。

That young man denied that he had started the fire before sunrise.

8 L( Z0 D( g4 c/ H% @That young man still denies having started the fire before sundown.

& l$ A: Y. J+ f& `6 a" A; O* s- D4 i

个人同意三楼的解释，having done和doing都是可以作为动名词使用，但是语言的简化是因为用了doing不会产生误解，照样理解，并且这样还更简单，所以才简化成这样，至于楼主提到的start的短暂性，这里我觉得其实根本不需要考虑，因为不管短暂还是延续性都是发生在过去的，用having done都是为了强调发生的时间的先后顺序。用一些的初中、高中的例句来解释：I am sorry for interrupting (或having interrupted） you./ I remember locking (having locked) the door. 理解起来都是一样的。
