发音与拼写Pronunciation & Spelling
Only 'ambivalent' (/æmˈbɪvələnt/) rhymes with 'equivalent': both have the stressed rime /ɪvələnt/. 'Prevalent', 'benevolent', and 'malevolent' share only the unstressed /vələnt/ ending, so they sound similar but do not rhyme. Be careful: 'bivalent' shares the spelling 'valent' but is pronounced /baɪˈveɪlənt/.
