SPECIAL NOTE: The Conditional tense is made by adding the word would:-
I would work all the time if I had a job.
I would be working if only I could find a job
I would have been working hard all day if I had not been so lazy!
I would have worked very well as a public relations officer.
Another special note:- The –ing suffix indicates the Present Participle of the verb: working. The –ed suffix indicates the Past Participle of the verb: worked.
Transitive: Transitive verbs are those which require to be followed by a direct object: example:- These verbs are bloody difficult. You could not say ‘these verbs are’
The direct object is ‘bloody difficult’.
