Abstract:Robert Frost is one of the most distinguished poets in America, who won Pulitz Prize four times during his life time. He occupies an important position not only in American literature, but also in world literature. Many of his poems are about New England country life, expatiating the inharmonious relationship between man and nature, and between man and man. The theme of loneliness can often be found in Frost's poetry, playing an important role. This is not only related to the society at that time but Frost’s bitter life in reality. Through an analysis of this theme in Frost's poems in North of Boston, readers can get a better understanding of his poetry, and what’s more, be triggered to rethink and reevaluate our modern life. 

　　　This paper falls into three parts: the first one deals with the loneliness caused by the barrier and inharmonious relationships in human reality. The second part illustrates loneliness resulted from conflicts between dream and reality. The last one explores loneliness manifested in the relationships between man and nature. 

　　　In summary, after a further and detailed study of the theme of loneliness in Robert Frost's poetry, we can get a better understanding of the poet, his poetry and the people of his times.

Key words: Frost; North of Boston; Loneliness

摘要:罗伯特·弗罗斯特是美国最富盛名的诗人之一，他四次获得普利策奖，在美国文学史乃至世界文学史上都占有重要地位。他的诗大多数都以新英格兰的乡村为背景，阐述人与自然、人与人之间的关系。孤独主题常出现在弗罗斯特诗歌当中，发挥了十分重要的作用。这不仅与当时的社会背景有关更与弗罗斯特本人的经历有着千丝万缕的联系。本文旨在分析《波士顿以北》中几首诗中的孤独主题，以便我们更好的理解弗罗斯特的诗歌，并从中得到一些对现代生活的启发和思考。

　　　本文将从三个部分对弗罗斯特诗歌中的孤独主题进行剖析:第一部分探讨人与人之间不和谐的关系造成的孤独。第二部分探讨梦想与现实之间的冲突给人们带来的孤独。第三部分探讨人与自然之间的矛盾造成的孤独。

　　　总之，通过对诗中孤独主题的阐释，我们可以领悟到弗罗斯特本人对自然、人、现实的热切关注，从而探索和解读他的世界观、人生观，进一步深化对他诗歌的理解。
