“英雄雙韻體”(Heroic Couplet),是壹種英國古典詩體,由喬叟首創。由十音節演化而來,每行五個音步（foot）,每個音步有兩個音節(syllable),第壹個是輕音,第二個是重音.
In prosody, Chaucer mostly used the ten-syllable line in rhymed couplets (later developed into the most fashionable "heroic couplet " of the 18th century).

Heroic Couplet（英雄雙韻體）refers to lines of iambic pentameter which rhyme in pairs: aa, bb, cc, and so on.
Iambic- the rhythm of a foot is a weak beat/sound followed by a strong beat.
