The correct answers are I want to be a doctor in the future., I usually listen to music on my way to work., and I am very interested in learning new languages.

This question tackles several classic translation traps!

• Articles: English requires the indefinite article "a/an" before professions (a doctor). We also say "in the future." Furthermore, "work" (as a general destination) doesn't take an article (go to work, not go to the work).

• Prepositions: You must listen to music (the verb listen requires to when there is an object). Also, you are interested in something, not with or by it.
