Assisted by the Chinese-English parallel corpus with one source text and its three different English translations,the paper analyzes the Chinese construction of BU A BU B. The study shows that the construction consisting of opposite morphemes is more popular than that of similar morphemes,and the former is often translated asneither… nor…while the latter is often literally translated. The order of A and B in the English translation depends upon the usual linguistic norms of the English expressions. The English translations of the construction are usually equivalent to their Chinese source texts,and the interlingual explicitation or implicitation is not so obvious. The translators' native language backgrounds have little affect on their translations,but the choice of words in their translations do reflect their language accomplishments to some extent.
