"While I am reading, he is writing."
Translation:Pendant que je lis, il écrit.
I hope this is not redundant, but several times I have heard "lis" pronounced with the S sounded on Duolingo. Isn't that wrong? Even if a vowel followed it, which it usually does not, and one carried the S, wouldn't it be a Z sound not that grating hissing S sound? Can Duolingo please correct this? "Quand je lis, tu lis" in my opinion, the S should not be pronounced. I am right, am I not?
