What is rhyming couplets?

It's difficult to answer in Chinese for this questions, sorry. But well, here it is-

Couplets are any two lines working as a unit, whether they comprise a single stanza or are part of a larger stanza. Most couplets rhyme (aa), but they do not have to. There are several set forms of the couplet and a myriad of variations based on line length and meter. All of the following rhyme "aa":

Short Couplet- iambic or trochaic tetrameter. From Maxine Kumin's "Morning Swim"
Into my empty head there come
a cotton beach, a dock wherefrom

I set out, oily and nude
through mist in oily solitude.


Split Couplet- the first line in iambic pentameter, the second in iambic dimeter. From Richard Steere's "On a Sea-Storm Nigh the Coast"
The weighty seas are rowled from the deeps
In mighty heaps,
And from the rocks' foundations do arise
To kiss the skies.


Heroic Couplet- two lines of iambic pentameter, also the last two lines of the English sonnet. From Richard Steere's "On a Sea-Storm Nigh the Coast"
Wave after wave in hills each other crowds,
As if the deeps resolved to storm the clouds.


Alexandrine Couplet- an alexandrine is a line of iambic hexameter, so an alexandrine couplet is two rhymed lines of such. These often come at the end of stanzas or poems and, in these cases, are also called codas.

Qasida- an Arabic form consisting of any number of lines all rhyming on the same rhyme.

The couplet can be a very lonely stanza, minimalistic. Poems whose content is melancholy or depressing, for example, can make good use of the couplet because--on the page--there is a lot of white space, emptiness, as opposed to writing in quatrains where the stanzas are blocks which limit the white space. As well, because the couplet can be so small, it is a good idea to pack it full of image and emotion, like a hard punch packed in a tight space, very concentrated. If the power in a couplet is not contained to the couplet, then you have a quatrain or something larger. This doesn't mean the idea and emotion cannot flow between or through couplets, I am only suggesting that each couplet be a powerful, emotionally-intensive unit to the whole.
