Hi dear friends ,
 
I have  doubth .
 
I have to rephrase this sentence  and I have to use the verb remember again 
 
 " I don �t remember if locked the gate this morning"
 
Which is the right answer:
 
I  don �t remember locking the gate this morning.
I don �t remember having locked the gate thismorning
 
 
 
 
And .......... is this preposition OK?
 
The health of our planet is OUT OF risk
 
 
 
Thanks in advance
