Hello

I have a probleme with a specific sentence.

The scientists have been researching on alternative energies for a long time.

Can someone transform this sentence into passive voice?

My idea was:

Alternative energies have been beeing researched by scientists for a long time.

But that sound a little bit weird for me...

Thx

Hello, Daniel - and welcome to English Forums.

Yes, that is weird. And "correct". That is why active-passive conversion exercises are a waste of student time. They are used only because they are easy for teachers to grade.
When I die and get to have my "So how come...?" conversation with God, asking why ESL teachers and students are so fascinated by the passive voice will be one of my questions.

Technically correct, but every grammarian I am familiar with says the continuous perfect and pluperfect tenses are not used in the passive voice.

Ask Him about the fascination with "indirect speech" for me as well, in case I don't get there. Maybe He'll let you e-mail me the answer "down there".
