Would you be so kind and as to check these sentences in terms of their correctness. and tell me if they are correct or not?

1. To preserve our natural resources, we have taken effective measures. With the addition of the comma, it's correct.
2. We have taken effective measures to preserve our natural resources.
3. To solve traffic problems in big cities, strict measures have to be taken soon. With the addition of the comma, it's correct.
4. In big cities, strict measures have to be taken soon to solve traffic problems. With the addition of the comma, it's correct.
5. In big cities, strict measures have to be taken to solve traffic problems soon. With the addition of the comma, it's correct but the position of "soon" in #4 is more natural.

See above.

Thanks for your help.
It's a bit funny.I firmly assumed it was the other way round.
I thought sentence No 5 sounds more natural.

Please take also a look at the following sentence.
She was taken to hospital with a suspected pulmonary embolism.
With a suspected pulmonary, embolism she was taken to hospital.

It's a bit funny. ​(Space required after a full stop.) I firmly assumed it was the other way round.
I thought sentence No 5 sounds more natural.

Please take also a look at the following sentences:
She was taken to hospital with a suspected pulmonary embolism.
With a suspected pulmonary (no comma here) embolism, she was taken to hospital. Grammatically correct but it's not a natural word order.

See above.

In your first post, the reason #4 sounds more natural is that I take it that the strict measures have to be taken soon, rather than the solving of the traffic problems having to happen soon. The first needs to happen in order for the second to happen.
