Have fun! :)

Note 1:   It's better to say "I'm very busy these days". You can say the same thing "I've got many things on the go at the moment" or use an idiom such as "I've got a lot on my plate at the moment."

Note 2:  "Here they are!" is a better way of introducing a list of options.

My favourite dictionaries are http://www.chinesetools.eu/chinese-dictionary/ and http://www.mandarintools.com/
