发音与拼写Pronunciation & Spelling
All six words rhyme with "boast" (/boʊst/, UK /bəʊst/): they end with the same vowel and consonant sounds. Toast, roast, and coast also share the spelling chunk "oast" with boast; ghost, post, and host spell the same sound as "ost". Do not confuse these with lookalikes such as "boost" (/buːst/) or "broad" (/brɔːd/), which look similar but sound different.
