I'm preparing for my writing French exam, and my teacher informed me some of my sentences are incorrect; I have a feeling I know which ones! Could you take a gander at them (because she can't be bothered to mark my notes)? Much appreciated!

1. Touristes peuvent acheter des souvenirs fascinant ou ils peuvent détendre sous les cerisiers beaucoup par exemple, qui est génial car je crois que j'ai besoin de déstresser.

Tourists can buy fascinating souvenirs or they can unwind under the many cherry trees for example, which is great because I believe that I need to de-stress.

3. Quand j'etais petit, moi et ma sœur n'aimions pas manger les aliments indigènes comme nous considéré que c'était trop degoûtant! J'adorais nager dans la mer j'aimais danser à la discothéque, mais maintenant, Je suis moins peur de manger les aliments indigènes et j'ai préfère bronzer plus que la danse puisque j'estime que la dance est trop fatigant!

When I was little, me and my sister did not like to eat the native foods as we considered that it was too disgusting! I used to love to swim in the sea and I used to love to dance at the disco, but now, I am less afraid to eat the native foods and I prefer to tan more than dance since I reckon that dance is too tiring!

5. S'il y a une éclaircie, nous allons aller in parc d'attractions comme je pense que ce sera immensément passionnant!
