here's how i get to this: 1- i have to go to work - mujhe kam par jana hai mujhe kam karne jana hai means - I have to go to do work Karna - To Do Like hacer in Spanish 2- i am ready to go to work - Main Kaam pe jaaney ko tayaar hoon. Kaam pe = On work Lit. meaning I am ready to go ON WORK. 3- "i have to get ready for work" my best try: mujhe kam par jaaney ke lie taiyar hona hai No need for forms of Karna Use Karna when the English sentence has forms of Do in it. Great Attempt :):) (Applause) If You have skype you can ask me there too. :) Hope It helps :)

i have to go to work= ham ko kam pe jana hae. im ready to go to work= main taiyar ho chuka hun kam par jane ke liye. i have to get ready for work=majhe taiyar hona hae kam pe jane ke liye.
