[Grammar] New airports will be constructed on islands.

[Son Ho]

Good afternoon, teachers!
I have changed sentence 1 into passive voice. Could you please tell me sentence 2 or 3 is grammatically correct? Would they be different or the same in comparison with sentence 1 if both of them were correct? Thanks a lot.

1. They will construct new airports on islands.
2. New airports will be constructed on islands.
3. New airports on islands will be constructed.

They are all grammatically correct and possible in the right context. In the first, though, we have no way of knowing who "they" are.

 

[Son Ho]

I think the third one in passive is incorrect, isn't it? I wonder if there are any situations in which we must keep the adverb phrase with the object? If not it can change the meaning of the original sentence.

1. Employers must pay all travel expenses for this training course.
2. All travel expenses for this training course must be paid by employers.
3. All travel expenses must be paid for this training course by employers.

Do we know which islands? If so, I would use the islands, and airports tend to be planned well in advance.

I think the third one in passive is incorrect, isn't it?

No. I agree with emsr2d2 that it's grammatical but unusual. However, it is possible in the right context.
For example,
Airports on islands will not be a thing of the past. In fact, by the middle of the next century, international aviation will see passenger numbers triple, supersonic jets will be the norm, and new airports on islands will be constructed.

Yes.

That's right, there are, and yes, it can.

Not incorrect does not mean natural or likely.

 

[teechar]

Was that meant to be "Not incorrect does not mean natural or likely"?

Starting a sentence with "I wonder" does not make it a question. It is simply a statement about what you are thinking. Also, anything you build (construct) is new when it is finished. So we don't build new things. We build something, and it's new (because it wasn't there before).

 

[teechar]

So we don't build new things. We build something, and it's new (because it wasn't there before).

I can't agree with that. It may not be the case in AmE, but in other varieties, it is quite common and natural to say build new things.
They're building a new railway station across from the town hall.
The old airport will be decommissioned and a new much larger one built.
A brand new hotel is going to be built in the centre of town.

 

[Tdol]

Was that meant to be "Not incorrect does not mean natural or likely"?

Yup. Thanks

Good point!

Yes.

Could you please tell me when we must keep the adverb phrase with the object?

Let's forget about the 'airport' example and focus on the one about travel expenses.

a) All travel expenses for this training course must be paid by employers.
b) All travel expenses must be paid for this training course by employers.

Tell us why you think sentence a) is better than sentence b). Think about the structure of the sentences. Which part is the subject in each case?
