小编摘要："To snap at someone" is to speak rudely, but snap can also be used as a noun. If we say something is a "snap" that means it's very easy and can be learned quickly.
今天Larry和Li Hua一起打保龄球，Li Hua会学到两个常用语：snap和spaced out.
(SFX of bowling alley)
LL: Hey, Li Hua, you look nervous. Have you ever bowled before?
LH: No, 我从来没打过保龄球，所以当然紧张啦！
LL: Don't worry, Li Hua, bowling is a snap. You'll figure it out in no time.
LH: 你说bowling是什么 - a snap? To snap不是对别人嚷嚷、说话态度很凶的意思吗？
LL: That's right. "To snap at someone" is to speak rudely, but snap can also be used as a noun. If we say something is a "snap" that means it's very easy and can be learned quickly.
LH: 噢，我懂了，snap用作动词的时候，意思就是对人很凶，不过你刚才说的snap是用做名词，要是我们说something is a snap, 意思就是很容易就能学会的事，哎，那不就是我们中文里所说的"小菜一碟"吗？
LL: Yes. So, now you'll understand what I meant by saying "bowling is a snap!"
LL: Well, if you think bowling is hard, then what do you think is a snap?
LH: 让我想想 -- 骑自行车挺容易的。我一个下午就学会了。
LL: So you think riding a bike is a snap -- I agree, once you learn how to ride a bike, it's a snap. Hey, Li Hua, you know what else is a snap?
LH: No, what else?
LL: Beating you at bowling is a snap. Look, I'm 50 points ahead of you.
LL: You're right, Li Hua. It's not fair. Here, I'll teach you. Then you'll see what a snap it is.
(Sound of ball being thrown)
LL: Li Hua, did you enjoy bowling?
LH: Yes, 保龄球挺好玩的，可是也挺累人的。
LL: Yeah, I agree. I feel kind of spaced out.
LH: 你说你觉得怎么样了 - spaced out? Larry, 你是身体不舒服吗？
LL: No, no. Feeling spaced out means feeling kind of detached and unfocused. I sometimes feel spaced out when I'm tired.
LH: 噢，我懂了，feeling spaced out意思就是"觉得昏昏沉沉的，注意力难以集中"。就是啊，一个人太累的时候是会感到昏昏沉沉，周围发生什么事都不知道。
LL: Yeah, but sometimes it might be for no reason. For instance, I might feel spaced out at class - I would be thinking about baseball, instead of listening to the teacher.
LL: All right, Li Hua. Now don't tell me you've never felt spaced out yourself.
LL: Last week, I was really stressed over the exams. I was so spaced out that I forgot my father's birthday. I felt terrible.
LL: No, he knows me very well - bowling is a snap for me; but exams always make me very nervous.
