Hello,
The beach will be crowded by foreign tourists if it does not rain.
Could you change the above sentence to a complete passive sentence or more sentences without changing its meaning? I am wondering whether the whole sentence qualifies as a passive sentence because the second part 'if it does not rain' cannot change into the passive one. In other words, the first passive part 'The beach will be crowded by foreign tourists' is mixing with the active part 'if it does not rain' in the same sentence. According to 'Guide to Grammar and Writing', the principle is no-mix-active-passive sentence:

By the way,I managed to change it to the following way of a complete two-part passive sentence but am unsure about its correctness. Could you correct it as well?
1. The beach will be crowded by foreign tourists if it has not been raining.
Thank you.
With best wishes.
