The similar hits of nouns and numerals in OETT and TETT indicate there is not highly significant difference between the two.OETT has more hits in proper nouns,verbs,adverbs(either lexical adverbs or functional adverbs),determiners,but TETT has more ad jectives,prepositions,auxiliary verbs,conjunctions and pronouns.Generally speaking,prepositions,conjunctions and pronouns occur more frequently in English than in Chinese.However,TETT exaggerates the grammatical features in the translation process(LL preposition-0.78,number-0.45,conjunction-0.02).The translation hypothesis“a general tendency to exaggerate features of the target language”(Baker 1993:244)is assumed to be true and will be further verified.
