Translation Exercise Unit 1 - Part 1 [Basic Spoken Chinese Practice Essentials] I am trying to learn mandarin and I am using the Basic Spoken Chinese Practice Essentials Workbook. Unfortunately there is no answer key to that book. Would be great if someone could check if I translated correctly.


Where is Ke Leien going? 


Kē Léi'ēn dào nǎr qù?
Kē Léi'ēn dào nǎr qù a?

I'm going to the cafeteria. How about you?


Wǒ qù shítáng. Nǐ ne?

Wang Jingsheng is going back to the dorm.


Wáng Jīngshēng huí sùshè.

Ke Leien is going to take care of some things.


Kē Léi'ēn qù bàn yìdiǎnr shìr.

You're going to the library; I also am going to the library.


Nǐ qù túshūguǎn. Wǒ yě qù.
