回复：只教密码，带博士生？我也来听课。A cute poem.

比方：

a little birdie flies in sky

a=unstressed

little=stressed/unstressed

birdie=stressed/unstressed

flies=stressed

in=unstressed

sky=stressed

in total we have syllables in this pattern:

unstressed stressed unstressed stressed unstressed stressed unstressed stressed

which is tetrameter
