A reverse in a sentence.

[coolpro]

In passivising (61)–(64) to become (81)–(84), not only have the Direct Objects of active sentences become the Subjects of passive sentences, another change has occurred: the Indirect Objects have ended up in phrases beginning with to: to the boys, to her, to the
student and to us.

That's not a question sentence.

Why is have the Direct Objects of active sentences become then, and not Direct Objects of active sentences [B]have become[/B]?

If that's not a question sentence, in what cases an auxiliary verb like have precedes the subject of the sentence? (Like when would we use have somebody done?)

Please use quotation marks. I could probably work out what your question means, but I don't have the time now.

After "not only" you generally change the word order.

Not only will you visit historic sites, but you'll also...
Not only am I angry, I'm disaapointed as well.
Not only have these become subjects...

I guess you meant we usually change the word odor.
