Which One is True ?

edyguardsWhich one is correct?

Suppose I want to write this sentence: "Barcelona has without a doubt become one of the best cities in the world."

edyguardsThis sentence consists of two clauses, am I right ?

No, not as corrected. Your original was of faulty construction.

So it is not possible to write such sentence, do you know some good examples that best describe the use of a sentence with two clauses consisting of one subject and two verbs?

Hiding under the bed, the man could not see what was happening above him.

(It cannot be done with two finite verbs.)

Thank you for giving an example, although I think that your example is a bit complicated for me.

What do you think about this one, "It is and will always be the best choice" ? This is a sentence ( that ) consists of two verbs and one subject.

edyguards This is a sentence ( that ) consists of two verbs and one subject.

It is indeed—but it has only one clause (which had a compound predicate). As I have said, you will not be able to construct a compound sentence with only one subject but two finite verbs.

A clause can have any combination of the following:
- a compound subject
- a compound verb

A sentence can have any combination of the following (but it must have one main clause):
- one or more independent clauses.
- zero or many dependent clauses

A compound verb is two or more verbs with a coordinating conjunction:

He looked, saw, jumped and ra

Thank you, let me think about your explanation for a moment ( a few hours is possible ) and once i have understood about this explanation, it is possible that there are more questions popping out.

So it is okay to have a sentence such as " It is and will always be the best choice ". It has one subject and two verbs .
