It is extremely interesting for us to read The Age of Exuberance:backgrounds to eigh-teenth century English literature by Donald Greene, who tries to see the eigh teenth century from a different perspective, observing it as an exuberant, luxuriant age full of variety. It is the eighteenth century that witnesses the emergence of many news things.展开更多
