Avoiding ambiguity with present participle constructions
The participle must relate to the subject of both verbs Reading my newspaper, I heard the doorbell ring ( =/ was reading my newspaper and / heard the doorbell ring ) Now compare "Reading my newspaper, the doorbell rang * This sentence suggests that the doorbell is the subject and it was reading my newspaper Reading is here called an 'unrelated participle' and the sentence is unacceptable However, this rule does not apply to a number of fixed phrases using 'unrelated participles', e g broadly/ generally/strictly speaking considering judging supposing taking everything into account
The complex sentence participle constructions
Strictly speaking, you ought to sign the visitors book before
entering the club (you are not strictly speaking)
Judging from past performances he is not likely to do very well in
his exams (he is not judging) When the participle construction follows the object it must be related to the ob|ect and then the sentence is acceptable
/ found him lying on the floor(= He was lying on the floor)
Past participle constructions in place of clauses

looked like a cloud

Past participle constructions in place of adverbial clauses
The past participle can also be used with a conjunction in front of it to
replace a passive
