Abstract: To resolve the problem of the lack of capacity for the reordering in Phrase-Based Statistical Machine Translation（PBSMT），this paper attempts to parse the input Chinese sentences to PBSMT，conduct the reordering of the sentences by a converter，pre-translate some types of phrases，and then translate the output from the above operation by a decoder.This paper focuses on the effects of the reordering for complex attributes linked by“de”，and the effects of the reordering and pre-translation of prepositional phrases，specific collocation phrases and phrases of noun of locality.Experimental results show that the reordering and pre-translation can significantly improve the BLEU values of the English translation by PBSMT.

Key words: statistical machine translation, syntactic reordering, pre-translation
