This paper tries to analyze the problems arising in translation of English adverbs to Persian. For this purpose, the researcher introduces all kinds of English and Persian adverbs for familiarity with them and then asks some translation students to translate some sentences (they are free to use a dictionary). Two English translation teachers were the raters and sentences were studied based on their translation. Correct, false translation and omission of the sentence were calculated for each adverb. The results of this research showed that the main problem in translating of the English adverbs is unfamiliarity with them.
