发音与拼写Pronunciation & Spelling
Pliocene /ˈplaɪəsiːn/ and Miocene /ˈmaɪəsiːn/ rhyme with each other, but none of these words rhymes with Pleistocene /ˈplaɪstəsiːn/: its stressed vowel /aɪ/ is followed by /stəsiːn/, not /əsiːn/, and the final -cene is unstressed. Pliocene is the closest lookalike but is pronounced /ˈplaɪəsiːn/. Scene is the most familiar everyday word with the same -cene spelling and /siːn/ final sound.
