Bonjour pouvez vous m aider svp ex 2 et 3

... is the most amazing film i've ever seen 
... is the biggest city in the world 
It is the most hostile environment 
It's the smallest car that exist
It's the best food i've tried 
This is the most impressive landscape 
It's the tallest building 

The redback spider the friendliest spider i've heard of 
Alan is the nicest person i've met
Ayers Rock is the most impressive mountain i've ever climbed
The box jellyfish is the deadliest creature i've read about 
The koala is the cutest animal i've seen 

Pour le 1er exercice je te laisse customiser ta phrase
