The study of English versions of Poems of Mao Zedong is not only highly beneficial to our aesthetic appreciation of the tremendous momentum and magnificent scene but also to our appreciation of the English language and to translate Chinese into English.By means of comparing and analyzing a variety of translation versions,we draw the following conclusion:Most of the Chinese character "Tian" in the poems of Mao Zedong can be used to convey three different implications,and their translations are supposed to vary according to the various meanings.The authors commented on these translation versions,and put forward their own opinions:When it refers to "Tiankong",it is mostly translated as "sky";when it refers to "Ziran",it is rendered into "nature";when it implies the sense of "Tiangong",it is usually transformed into "heaven".There are also a very few Chinese character "Tian" in the poems of Mao Zedong should be translated according to the context,conforming to the principle of maximally reproducing the artistic conception of the original poem.
