最近李華看到朋友Kevin經常向大家要用過的吸管，覺得奇怪，便決定和Larry一起探個究竟。李華會學到兩個常用語：shady和to stock up。
LH: Larry, Kevin在做什么啊?
LL: Hmmm...that's a good question.
LL: I don't think so, Li Hua. If they really went broke, he would just sell his Mercedes or iPhone.
LL: But it's a bit shady what he's doing. Why would someone collect straws?
LL: Shady means suspicious or questionable. Kevin collecting a bunch of straws is definitely suspicious.
LL: Rather than asking him, why don't we sit back and observe him for a couple of days, and see what he's up to.
LH: 你說要觀察幾天？ 好??！我們就做一回偵探！
LH: Larry! Kevin 今天沒有再要吸管了耶。他好像完成了他的任務。那我們要怎么找出真相呢？
LL: He's not collecting straws anymore? Is he doing anything else that's shady?
LL: The art classroom? Maybe that's where he stocks up all the straws! He wants to use those to create some artwork!
LH: 你說stock up... 是儲藏的意思嗎？
LL: Yes. To stock up means to store. He probably already put all the straws he's collected in the storage room, and he is now trying to create an artwork.
LL: Yup. That has to be it.
LL: Hmmm..really? That's even more shady then.
LH: 但Larry, 我很好奇。為什么shady是可疑的意思呢？跟suspicious這個字也沒什么關系啊。
LL: A shade is a place that is dark. Usually, things that are suspicious are done in the dark. Therefore, we say someone or something is shady when that thing or person is very suspicious.
LL: That's right.
LL: Let's wait another day and see. Maybe we'll know tomorrow!
LL: Li Hua! You're here so early today.
LH: 是啊。你在做什么呢？Why do you look all shady?
LL: I look shady?? What are you talking about?
LH: 我剛才明明看到你和Kevin在悄悄說話，Does it have anything to do with the straws that Kevin stocked up?
LL: Ohh that?! Shhhhh. I was just talking to Kevin to see what he was up to.
LH: 你趁我不在的時候去問Kevin?! 干嘛不叫上我一起，真不夠意思。
LL: But guess what I found out?
LL: Here, follow me! Let's go into the classroom where we can sit down and talk.
李華跟Larry一起走進教室, 等在教室里的很多一起喊"Happy Birthday李華!"
LH: 天??！Larry, 你們原來是用吸管做了這條船給我當生日禮物！我還以為....
LL: Well, we had to give you a surprise, but you realized Kevin was stocking up on straws. I had to pretend not to know.
LH: 謝謝啦！ 現在終于知道Kevin為什么鬼鬼祟祟得在收集吸管了！
今天李華從Larry那兒學到兩個常用語，一個是shady,“可疑”的意思。另一個是to stock up, 也就是“儲藏”。
