Translation:There are cities and states in America.
Trying to make this sentence sound smoother: would "there are cities and states in america" fit?
35,000 urbes sunt in America https://www.reference.com/geography/many-cities-united-states-cfb3be08284e6a62
The onset of 'civitas, civitates' should definitely be pronounced /siːv/ and not /kiːw/ as in the audio recording behind this sentence.
The course is using reconstructed pronunciation (our current best guess of how educated Romans like Cicero would've spoken) where indeed /ki:w/ is correct. For more info check out the excellent Vox Latina by Allen. That's not to say /si:v/ or /t͡ʃ:iv/ are wrong, they're perfectly valid alternative pronunciations, but they're more faithful to the modern Romance languages than the original Latin.
Perfectly normal in Oxford reconstructed pronunciation as opposed to church Latin
To add to what the others are saying: both C's and G's are always pronounced hard in Latin, despite how English loanwords are.
