    Do you have an English name? I have noticed (注意到) one thing in China: lots of people have uncommon(不常见) English names.

    One of my Chinese friends calls herself Big Bird, like the character(角色) from the children's TV show Sesame Street(《芝麻街》). Another one of my friends is an English teacher. She had students with the names like Tomato and Potato. There were also two girls named Echo. Before I came to China, I had never met anyone with these names.

    People choose these strange names for different reasons. Sometimes they copy the names from someone famous. Other times, they want names that have the same meaning as their Chinese name.

有三张正面分别写有数字﹣2，﹣1，1的卡片，它们的背面完全相同，将这三张卡片北背面朝上洗匀后随机抽取一张，以其正面的数字作为x的值，放回卡片洗匀，再从三张卡片中随机抽取一张，以其正面的数字作为y的值，两次结果记为（x，y）．

（1）用树状图或列表法表示（x，y）所有可能出现的结果；

（2）求使分式$\frac{x^2-3xy}{x^2-y^2}$+$\frac{y}{x-y}$有意义的（x，y）出现的概率．
