【答案解析】[听力原文]
Sarah: I have been learning English for about six years. I still find pronunciation very hard. Do you think I should aim to speak English with a native-speaker pronunciation.
Bill: I think, in learning English, the most important thing is to be understood easily. For most learners, it is not necessary to speak like a native-speaker.
Sarah: But I want to be an interpreter after graduation. I think pronunciation is quite important for me.
Bill: That"s true. For those who want to be teachers or interpreters, an ideal pronunciation is the ultimate goal.
Sarah: I find some children do not want to speak English with a native-speaker pronunciation.
Bill: In general, children can imitate strange sounds very easily well. However, it is true that most children do not want to sound "English" when they are speaking English.
Sarah: Yes. I found that too. I just wonder why they don"t want to sound "English."
Bill: I think the main reason is that most of them want to belong to a group. Even if a child can speak English like a native-speaker, he or she will usually choose not to—unless the rest of the group speak with a native-speak pronunciation.
Sarah: Adults usually find pronunciation very difficult, though they try very hard to imitate the native-speaker pronunciation.
Bill: Many reasons have been offered for the difficulties which many adults find with pronunciation. But if an adult really wants to achieve a native-speaker pronunciation, he or she can.
Sarah: Really. This encourage me greatly. But I still find it"s hard for adults. I don"t know why.
Bill: I think the main reason is that adult students have a strong sense of national identity.
Sarah: A sense of national identity. I don"t quite understand it.
Bill: They want to be identified as a German or Brazilian speaking English. In my opinion, this sense of national identity is more important than other explanations, such as the greater anxiety of adults or the effect of their own language habits.
Sarah: Maybe you are right. Anyway, I will try to perfect my English pronunciation.
