发音与拼写Pronunciation & Spelling
No common word fully rhymes with /ˈfɒsfərəs/. Phosphor (/ˈfɒsfər/) shares the same first two syllables. Chorus (/ˈkɔːrəs/) and porous (/ˈpɔːrəs/) look like they should rhyme but have no /f/ and a different vowel; they are useful spelling lookalikes only. For the ph = /f/ spelling, compare phonics (/ˈfɒnɪks/) and phobia (/ˈfəʊbiə/).
