Participles
There are two kinds of participles: one ending with-ing (the present participle), and the oth
er ending with-ed (the past participle). Which form to use depends on the relationship between the verb and the noun described. Study the following sentences.
a. The trembling old man stood by the broken window.
b. Frightened by a strange noise downstairs, he went down slowly, holding his gun in his hand.
c. Together the friends followed the trail, picking up the fallen strawberries as they went along.
When we use a verb to describe a noun, there must be a logical relationship between them: the noun either carries out the action or receives the action. If the noun carries out the action, it is the logical subject of the verb, and we should use the present participle. If the noun receives the action, it is the logical object of the verb, and we should Use the past participle.

Complex participle phrases
a. Watching the movie, the boy became very excited.
b. Having watched the movie, the boy became very excited.
c. Hurt in the game, Beckham may not be able to play in the coming World Cup match.
d. Having been hurt in the game, Beckham stayed in hospital for about two weeks.鹿晗的电视剧
As can be seen in these sentences, the present participle may appear in three different forms (Sentences b, c and d) besides its original form (Sentence a). The italicized part in Sentence b is the perfect aspect of the present participle, which means that the action of the participle verb takes place before that of the predicate verb. So, Sentence a means that the boy became excited while he was watching the movie, but in Sentence b the boy be-came excited after he had watched the movie.
Hurt in the game in the third sentence looks like a past participle. However, we can also regard it as the passive voice of the present participle with being omitted.（In this passive form, being is usually omitted, and then it becomes the past participle.） In Sentence d, t
he italicized part is the perfect aspect of the passive form of the present participle.
