Grammar: perfect gerund ,perfect participle, present participle
I. Participles
There are three kinds of participles in English: present participle, past participle and perfect participle. You probably know the first two from certain tenses and adjective forms. Apart from that, participles are also used to shorten sentences.
1. Present Participle
The present participle is the ing-form. You surely know this form:
* from progressive / continuous tenses (e. g. Present Progressive) – I am speaking.
* as an adjective form – The film is interesting.
* as a gerund – He is afraid of flying.
Not the exceptions in spelling when adding 'ing':
Exception Example
final e dropped (but: ee is not changed) come – coming (but: agree - agreeing)
final consonant after short, stressed vowel is doubled sit – sitting
final consonant l after vowel is always doubled (in British English) travel – travelling
Final ie becomes y lie – lying
The present participle can be used to describe the following verbs:
come, go, sit
Example: The girl sat crying on the sofa.
The present participle can also be used after verbs of the senses if we do not want to emphasise that the action was completed. (see Infinitive or Ing-Form)
feel, find, hear, listen to, notice, see, smell, watch
Example: Did you see him dancing?
Furthermore, the present participle can be used to shorten or combine active clauses that have the same subject.
Example: She left the house and whistled. – She left the house whistling.
2. Perfect Participle
The perfect participle can be used to shorten or combine clauses that have the same subject if 
*  one action (the one where the perfect participle is used) is completed before the next action starts.
Example: She bought a bike and cycled home. – Having bought a bike, she cycled home.
*  one action has been going on for a period of time when another action starts.
Example: He had been living there for such a long time that he didn't want to move to another town. – Having lived there for such a long time, he didn't want to move to another town.
The perfect participle can be used for active and passive voice.
* active voice: having + past participle (Having cooked, he set the table.)
* passive voice: having been + past participle (Having been cooked, the food looked delicious.)
II. PERFECT GERUND AND PERFECT PARTICIPLE: 
- Cách dùng tương tự Present Participle & gerund nhưng về mặt ý nghĩa, nó diễn tả hoặc nhấn mạnh sự hoàn thành của 1 hành động
Eg1: Finishing my homework, I went to bed: Sau khi làm xong bài tập tôi đi ngủ
Having finished my homework, ... : Sau khi đã làm xong bài tập ...
* Câu thứ hai nhấn mạnh việc đi ngủ chỉ xảy ra sau khi đã làm xong bài tập.
Eg2: I approve of helping the poor: Tôi đồng ý với việc giúp đỡ người nghèo
I approve of having helped the poor: Tôi đồng ý với việc các bạn đã giúp đỡ người nghèo
* Câu thứ hai diễn tả ý giúp đỡ người nghèo này đã xảy ra rồi.
- Perfect gerund:
Eg: I had had dinner and then I went out for a walk last night.
~~> Having had dinner, I ...
* Use: Rút gọn & diễn tả 1 hành động xảy ra trước 1 hành động khác/
- Perfect participle:
Eg: The denied having been there.
PREP/ VERB + HAVING V3
* Use: diễn tả hành động xảy ra trước hoặc ko xảy ra trước.
