I know how to construct a simple present tense sentence as following. However, is it possible to use this structure to construct sentences for other tenses such as past, future, present/past/future perfect?


Having provided such valuable services, the television play a prominent part the world.


Please someone tell me whether following sentences are grammatically correct or not. Further more is those are natural?


Having provided such valuable services, they company could be the best organisation in the 1900s.

Having provided such valuable services, they will be able to establish a lucrative business.

Having provided such valuable services, they had been playing a vital role in society.

Having provided such valuable services, they has been playing a vital role in the society.

Your main clause (underlined) is faulty. The sentence itself seems a patchwork of random phrases.


Having provided such valuable services, they the company could be the best organisation in the 1900s.

Having provided such valuable services, they will be able to establish a lucrative business.

Having provided such valuable services, they had been playing a vital role in society.

Having provided such valuable services, they has have been playing a vital role in the society.

Having provided such valuable services, they will have been playing a vital role in the world.

They are all mostly OK (as shown), but the first and the last are somewhat awkward. The second one is the most convincing.

In any case a "having" participle construction is interpreted as happening before the action or state expressed in the main clause.
