In my paper, I compare the characteristics of English long sentences and Chinese long sentences, and I also talk about how to translate long sentences. There are at least two or three modifiers involving no less than one subordinate clause in an English long complex sentence. There are at least twenty words and three or four comparatively independent phrases that are connected together by meaning in a Chinese sentence. The differences between them are the rules of making sentences and the structure. In my paper I also talk about how to translate long sentences, and here are the rules: a) break the formal structure; b) reorganize every part according to the habits of the receptor language. If we can master the rules, we can translate the English and Chinese long sentences better.
