Am i understanding the lesson correctly by following the below example for the following translation?

English: How can I not go?  Here, i'm intending to mean the sense that I don't want to go, am searching for a reason to not go, but i need to go or am required to go, etc.

Would that be: comment puis-je ne pas aller ?

Merci!

For Indiana Jones lived through extraordinary adventures 

I used "a vécu par" for "lived through".  Is this incorrect?

I don't understand why this is plural?

Je me lave après que tu te lèves.I wash after you get up.

Could someone explain the subtleties of these three? 

I used 'environ' which was marked incorrect.

Each example of aux alentours de was paired with a 24-hour clock and vers with the 12-hour clock. Are they interchangeable?

I am wondering how to form a statement using would (le conditionnel?) from a past perspective.  As in "I spent a lot of time deciding what I would eat for lunch today".  Could someone tell me if the below is correct?  Apologies for the spelling/accent errors as I am typing on a computer where i don't know how to type those, but i've tried to approximate the critical ones below.

j'ai passe' beaucoup de temps `a decider quoi je mangerais pour dejeuner aujourd'hui.

Or

maybe i should say "quoi j'allais manger pour..."?

Merci d'avance.

"un cadeau surprise." Why not "un cadeau surpris?"
