between the first generation and the second generation because they dont have the same native language. Also, the second generation is losing their identity. Especially in America, there are many immigrants that came from different countries to succeed in the States. Because they suffer in lots of areas such as getting a job and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more successful. Because of this situation, their children are losing their ethnic identity. For example, my aunt, who has been living in Chicago for twenty-five years, has three children and they were all bom in the States. The eighteen-year old daughter speaks English as a native language and she speaks Korean very well too. She has no problems talking with her parents, but she still doesnt understand Korean jokes, and there are sometimes misunderstandings. The second daughter is fourteen years old, and she doesnt want to speak Korean. My aunt often gets upset with her because she is very Americanized and they cannot understand each other. Even when my aunt punishes her, this daughter does not understand what my aunt is talking about. The third child is a twelve-year-old son. He speaks English to his parents and my aunt speaks Korean to him as she does to the second daughter. He also has a problem communicating with his parents. My aunt is trying to teach him to speak both languages, but it is very hard for him because he speaks English all day and does not understand why he should learn to speak Korean. We must realize that language is important and valuable for many reasons. Immigrants should make an effort to make their children understand their heritage by teaching them the parents language. This is very important, not only for the harmony of the family, but also in helping the second generation establish their identity.
