Pouvez-vous m’aider à corriger les fautes

I gave him his book yesterday.

I went to the cinema last night.

I lived in London for years now.

I must do my homework(s ?).

If it's windy, we will/can go surfing. (Dépend, will pour "nous allons aller surfer" et can pour "nous pouvons aller surfer")

I don't want to become an engineer.
