发音与拼写Pronunciation & Spelling
No common word rhymes exactly with 'bottom' (/ˈbɑtəm/). The listed words are lookalikes: 'atom', 'custom', and 'autumn' end in the same /təm/ sound as 'bottom', but their stressed vowels differ (respectively /æ/, /ʌ/, and /ɔː/), so they do not rhyme. 'cotton', 'rotten', and 'button' share the spelling -tton, but they end in /tən/ (not /təm/); be careful not to confuse the final m and n.
