M: Did you leave it in the shop? 你把它落在商店了吗 nǐ bǎ tā là zài shāngdiàn le ma?

S: Left it in the shop? 落在商店了? Là zài shāngdiàn le? Let me think. 我想想 wǒ xiǎngxiǎng. A! Shìde. 我把它落在商店了 wǒ bǎtā làzài shāngdiàn le.

M: Hurry up, 快点儿 kuài diǎnr.

S: Ok, Ok!

S: I hope my wallet is still there.

M: Meanwhile, let's look at the new things. I asked Stuart, 你把它落在商店了吗 nǐ bǎ tā . The bǎ in bǎ tā is the same bǎ as in bǎ something fàng zài somewhere. But here we use 落 LA là, instead of fàng. Là means 'to leave accidentally', as in 'I left it in the shop' là zài shāngdiàn le. So, did you leave it in the shop? nǐ bǎ tā là zài shāngdiàn le ma? Say it, everyone. 你把它落在商店了吗?

S: Now, remember 房间 ? Duìle. Room. So now everybody say, I left it in my room.

M: Completely correct. 完全正确 wánquán zhèngquè. 我把它落在我的房间了 wǒ bǎtá làzài wǒde fángjiā le.

S: Don't forget, làmeans you left it accidentally, forgot it. If you meant to leave it, you use 留 LIU liú. So say, He left all the money in my room.

M: Wánquán zhèngquè! 他把钱都留在我的房间了 tā bǎ qián dōu liú zài wǒde fángjiān le.

S: Impossible! 不可能 bù kěnéng!

S: Back to the dialogue!

M: You must go back at once. 你得马上回去 děi, DEI, third tone, means 'must' or have to, děi. Mǎshàng, remember, means 'immediately', so, all together, nǐ děi mǎshàng huí qù, nǐ děi mǎshàng huí qù. Hurry up 快点儿 kuài diǎnr.

S: I'm sprinting!

S: Hǎo. Let's finish with the dialogue. Yī èr sān, kāishǐ! 我的钱包丢了 wǒde qiánbāo diū le.

M: 你把它落在商店了吗 nǐ bǎ tā là zài shāngdiàn le ma?

S: 落在商店了 là zài shāngdiàn le? 我想想 wǒ xiǎngxiǎng. Shìde. 我把它落在商店了 wǒ bǎ tā là zài shāngdiàn.

M: 你得马上回去 nǐ děi mǎshàng huí qù.
