今天早上Larry和李华和一对朋友Charles and Lisa约好一起打网球。李华会学到两个常用语：pumped和iffy.
LL: I'm really pumped about today's tennis match. How about you, Li Hua?
LL: No, I'm not nervous. Pumped means energized and excited. I'm looking forward to today's game because I think it will be a lot of fun.
LL: That's right! What about you? Aren't you pumped about the game?
LH: 嗯，我是很期待这场比赛，不过，我可不敢说我像你那样pumped. 我对体育没有象你那样感兴趣。
LL: Yeah, I guess I get particularly pumped about sports. If sports don't get you all that pumped up, then what does?
LH: 我呀，我是一谈起旅行就特别兴奋。I'm pumped about travel。只要想到要去旅行，我就非常兴奋。明年暑假，我计划要到温哥华去玩一个星期。
LL: You're pumped about going to Vancouver? What is there to do in Vancouver?
LH: 到那儿去干什么？ 温哥华有很多美丽的高山。景色一定很壮观。还有那里的野生动物！我一想到有机会看到野生麋鹿我就特别兴奋。Yes, I'm pumped about going to Vancouver.
LL: Well, I guess people get pumped about different things. Personally, I don't get very excited about mountains and wild animals.
LL: Hey, tennis is fun and it's good exercise.
LL: I don't know. It's iffy that we'll even be able to get tickets. Tickets for things like that sell out very quickly.
LH: 那倒也是，像这种热门球赛的票八成已经卖完了，所以你刚才说iffy，就是指我们“不太可能”买到票，是吗？Iffy肯定是从if 这个词来的。
LL: That's right. If something is "iffy"，that means that it is uncertain or even a little unlikely.
LL: Yeah, but even if I can get tickets, it's iffy that we'll be able to afford them. Tickets for games like that tend to be expensive, too.
LL: Sure, I'll call the ticket vendor this afternoon. But it's iffy that they have half-priced tickets for students.
LL: Speaking of which, wasn't that last game fun? Do you think Charles and Lisa would play with us again?
LL: But it's iffy that they'll want to play against us again.
LL：Can't you see? They were defeated by us every round. It's really iffy that they had any fun this morning.
