发音与拼写Pronunciation & Spelling
All six words rhyme with /iːtʃ/: the stressed vowel and following consonant exactly match. Each shares the transparent spelling chunk "each". Beware lookalikes that sound different: leash /liːʃ/ ends in /ʃ/, and leak /liːk/ ends in /k/, so they are not rhymes. Also, leech (a bloodsucking worm) is a homophone of leach but is spelled with -eech.
