英国四大挽歌是？（英语回答）

Do you mean the most famous elegies in English Literature? or musical elegies?

If you meant literary elegies there are quite a few famous ones:
1. Edmund Spenser's "Astrophel "
2. Chidiock Tichborne's "Elegy"
3. Ben Jonson's "On My First Sonne"
4. John Milton's "Lycidas"
5. Thomas Gray's "Elegy Written in a Country Churchyard "
6. Alfred Tennyson's "In Memoriam A.H.H."
7. Percy Bysshe Shelley's "Adonaïs"
8. Charlotte Turner Smith's "Elegiac Poems"

至于哪个属于“四大”，我就不清楚了。
well, i told you I was not clear which could be categorized into the most famouse "4". Besides, difference scholars may have different opinions on which is greater than the other, right? You may need to go back to your English Literature books to find out.
