Victor: Hello, 我们是戴尔老师Victor。
Nancy: Nancy。
Victor: Hi, Nancy! How are you doing?
Nancy: Fine, Victor. How are you doing?
Victor: Fantastic!
Nancy: Yeah.
Victor: 这就是我们昨天学的和好朋友打招呼的方式，那么“好朋友”用英文怎么说呢？
Nancy: He's my best friend. Your best friends basically are your closest friend or your favorite friend, but we say "closest" instead.
Victor: 噢，best friend是“最好的朋友”、“铁哥们”，那么，“比较不错的朋友”我们也可以说close friend。Nancy, 我这个人最喜欢交朋友了，好朋友可不止一个，那怎么办啊？
Nancy: Well, do you have a number of best friends? You are lucky. And you say: "He's one of my best friends." Victor, you are one of my best friends.
Victor: Oh, Nancy, you're so sweet! 注意这里用的是复数friends。
Nancy: He's my best friend.
Victor: He's my best friend.
Nancy: He's one of my best friends.
Victor: He's one of my best friends. Very nice! Okey, see you later, everybody.
Nancy: See you next time!
