Y: Hi, 大家好。我是杨晨。
P: And I'm Patrick. And today we are playing a game of tennis.
Y: Patrick It's your serve!
P: To serve is to put the tennis ball in play by throwing it up into the air and hitting it with a racquet.
Y: 别罗唆了，赶快发球。Just serve.
P: OK. Here I go! (thwok, thwok) Good return, Yang Chen!
Y: Hey, Patrick, 你的球 出界了。So it is my point.
P: That means the score is "Love Fifteen". Love for me and fifteen for you.
Y: Love? 爱？这和爱情有什么关系？
P: Love in tennis scoring means “Zero”。
Y: 好浪漫。 可是我怎么会有15分呢？
P: Tennis scoring is very complicated, isn't it? To win a game a player must win four points and two more points than his opponent. The first point is called "fifteen".
Y: 那么 the second point is called "thirty"?
P: That's right. The second point is called "thirty," and the third point is called ...
Y: Forty-five?
P: No.
Y: Why not forty-five?
P: It's just the tradition now, the French started it .
Y: 那他们的数学一定不好。
Okay, serve again, Patrick! (Thwok, Thwok).
P: Oh no, I missed the ball!
Y: "Love thirty"!
P: I guess I'm losing.
Y: But at least you still have love!!!
