Participating in speech contests gives language learners a good opportunity to know more about the culture of the target language. Such contests allow students to learn how to write a speech for a particular audience, how to introduce a speaker, how to deliver a speech, and how to say ＂thank you＂ to the speaker. Participation in speech contests can promote insight and understanding through a comparison of American culture and the students＇ native culture. Such comparison is intended to promote better understanding of both cultures.展开更多
