In recent years, with the rapid development of economic globalization, the desire of modern people to know foreign culture is becoming stronger and stronger. As a part of culture and an important carrier of culture, language has very close relationship with culture. Idioms, the gems of language, are fixed sentences or phrases which are concise in form and wisdom. And the proper idiom translation can not only faithfully express the content and thought of the original works but also widen people＇ s cultural horizon and enrich their vocabulary. However, there are a lot of harri- ers and difficulties in translating idioms because they are strongly culture-loaded. Therefore, in order to render idioms faithfully and effectively, it is a must for a translator to pay much attention to the different cultural backgrounds between China and English-speaking countries and make use of the methods of idioms translation in a flexible way.
