Dialogue 1
Jingjing: Hi Mark, are you ready to head out?
京晶：嗨，馬克，準備好出門了嗎？
David: Actually, I'm not Mark. I'm his twin brother, David.
大衛：其實我不是馬克。我是他的孿生兄弟大衛。
Jingjing: What?! I know it's you, Mark. You're just putting me on.
京晶：什么？！馬克，我知道是你。你只是在讓我上當。
David: No, really. I can show you my passport later.
大衛：不，是真的。我一會兒可以讓你看我的護照。
Jingjing: This is some kind of weird joke. I'm sure of it.
京晶：這是一個好奇怪的笑話。我肯定。
David: Well, Mark told me you planned to go out for a long walk with him. A work thing came up; and, he couldn't get out of it. So, since I'm visiting for a few days, I thought I'd take his place.
大衛：呃，馬克告訴我你打算和他一起出去散個長步。可是他突然來了工作; 又無法擺脫。所以，正好我來這邊拜訪幾天，我想可以代替他吧。
Jingjing: Uh, ok... Do you know much about Beijing?
京晶：呃，好的......你對北京了解多嗎？
David: Mark's told me a few things; and I'm a history buff. But I don't know how to get around.
大衛：馬克告訴我一些了;而且我是歷史迷。但我不知道怎么能到處逛逛。
Jingjing: I can help with that. The cool thing about Beijing is that there are long parks all over the city. So, it's possible to walk for a whole day, shaded by big trees almost all the time.
京晶：我可以幫忙。北京最酷的事情是整個城市到處都有很長的公園。所以，可以在大樹的綠蔭下走上一整天。
David: And, today, we're going to put that to the test, isn't that so?
大衛：所以，今天我們要試一試，對嗎？
Jingjing: That's right. I thought we'd start out on yellow bikes, then go by foot once we get to a park, and then pick up bikes any time our feet get tired.
京晶：沒錯。我想可以先騎上黃色自行車，到達公園后再走路，然后在我們的腳走累的時候隨時再騎上自行車。
David: Yellow bikes? What are those?
大衛：黃色自行車？是什么？
Jingjing: They're shared bicycles. Haven't you seen them all over the city?
京晶：共享單車。你沒有在城市各處看到過它們嗎？
David: I've seen tons of bikes. Come to think of it, a lot of them were yellow.
大衛：我見過很多自行車。仔細想想，很多都是黃色的。
Jingjing: Those are bikes anyone can rent. One of the largest companies paints their bikes yellow, and calls them 小黃車(xi?ohuángchē).
京晶：這些是人人可租用的自行車。其中一家最大的公司將他們的自行車涂成黃色，并稱它為小黃車
David: That's a catchy name. I know 小黃 is a colloquialism for taxicab. And 小黃人 refers to those ubiquitous minions from the Despicable Me movies.
大衛：這真是一個吸引人的名字。我知道小黃是出租車的俗語。小黃人指的是電影“神偷奶爸”里面無處不在的小人兒。
Jingjing: I see you share Mark's way of thinking. Let's get going now, shall we?
京晶：我覺得你跟馬克的思維方式很像。那我們現在準備出發吧，好嗎？

Dialogue 2
Jingjing: Ok, here are several bikes. Let's look them over to see which ones are in the best condition.
京晶：好，這里有幾輛自行車。讓我們看看哪些單車是狀況最好的。
David: These two are in tip top shape. How do you actually rent it?
大衛：這兩個都最好的。你怎么租呢？
Jingjing: That's easy, you just scan the QR code, and pay the fee with your phone.
京晶：很簡單，您只需掃描二維碼，然后用手機支付費用。
David: Oh, the thing is, I haven't set up any online payments through my phone.
大衛：哦，問題是，我沒有通過手機設置任何在線支付。
Jingjing: No problem. I can rent them both.
京晶：沒問題。我可以租兩個。
David: Wow, the bike feels a little clunky, but rides pretty smoothly.
大衛：哇，自行車感覺有點笨重，但騎得卻很順。
Jingjing: Yep. The best thing is, we can ditch these anywhere and rent other ones along the way.
京晶：是的。最棒的是，我們可以在任何地方拋下這些單車，然后在沿途再租別的單車。
Jingjing: Ok, Mark—I mean, David—: There's a park up ahead. So, let's pull up to the curb and lock them up.
京晶：好的，馬克 - 我的意思是，大衛 ，前面有一個公園。所以我們把它們停在路邊然后鎖起來吧。
David: Great. So, I just trigger this lock on the back wheel?
大衛：好的。那么，我只是需要在后輪上鎖起這個鎖？
Jingjing: That's all you have to do. This park goes on for a few kilometers. We could get to the other end, and then look for some place to have lunch.
京晶：這就是所有你需要做的了（就這么做）。這個公園有幾公里長。我們去可以到另一頭，然后找地方吃午飯。
David: Is it free to enter the park?
大衛：進入公園是免費的嗎？
Jingjing: Yes, this one is. There's a gate just so cars don't go in and so that the park can be closed at night. Other parks in Beijing cost a few yuan, usually less than 10 unless they're historic sites.
京晶：對，這個是。這有一個門，汽車不能進，所以公園可以在晚上關閉。北京的其他公園要花費幾塊錢，通常不到10元，除非它們是歷史遺跡。
David: That's a good deal. Hey, if there's something I can pay for with cash, let me take care of it, since I can't pay for stuff with my phone.
大衛：真劃算。嘿，如果有什么可以用現金支付的讓我來吧，因為我不能用手機支付買東西。
Jingjing: Both you and Mark are stuck in the 20th century. Don't worry about it.Well, we picked a fine day for a walk.
京晶：你和馬克都停留了在20世紀了。你不用管了。你看，我們選擇了多美好的一天來散步。
