发音与拼写Pronunciation & Spelling
Words ending in /ɛkt/ with stress on the final syllable — sect, dissect, detect, respect, erect — genuinely rhyme with bisect. Insect shares the /sɛkt/ ending but stresses the first syllable, so it is a near rhyme rather than a true rhyme. Beware lookalikes such as biscuit /ˈbɪs.kɪt/, which sounds very different.
