发音与拼写Pronunciation & Spelling
All six words end with the sound /aʊt/ and rhyme with the final -out of rollout. Out, about, shout, layout, and trout share the exact spelling -out; doubt rhymes but is spelled -oubt, so don't rely on spelling alone. Beware of lookalikes such as route (often /ruːt/ in American English), which does not rhyme with out.
