"She looked at him, because he is handsome."
Translation:Ŝi rigardis lin, ĉar li estas bela.
Basically this sentence is implying that he is still handsome to this day. It's a property that isn't really expected to change.
What do you mean with future tense? There is no future tense in either the Esperanto or the English sentence.
i think he refers to the tips and notes-section that said sth like that - for example in esperanto you say Kion vi faros, kiam vi estos (!) gepatroj? - whereas in english you would say What will you do when you are (!) parents? ~~ he is wondering why it is different here ~~ the answer btw: i think it is because the sentence "because he is handsome" is not sth that "happened" in the past - it just describes a fact, that was true in the past, but that is still true now
If it was something only relevant then, it would of course be past:
Ŝi rigardis lin, ĉar li legis interesan libron.
look is active, like listen; see is more passive, like hear.
When you look at something or listen to something, you're directing your gaze or your ears towards the source on purpose - then you receive those visual or auditive impressions and see or hear them. But you can also see something out of the corner of your eye or hear something in the middle of the night even if you weren't looking or listening on purpose.
I see you're studying Spanish as well. Spanish makes pretty much the same passive/active distinction with ver vs. mirar, and oir vs. escuchar.
Nothing. Just one of several possible word orders that haven't been added to the list of accepted translations for this sentence.
thanks. I think there is actually a bug in app... it doesn't accept the x thingy anymore (the replacement to the accented letters)
I think using 'x' in lieu of circumflex or breve marks is discouraged. If you're on the website, there should be buttons for inputting the special characters. If you're on a phone, you should be able to access special characters or keyboards on your own.
Tricky, since keyboard support on stock iOS is not there - Esperanto is simply not one of the supported languages (yet). Not sure what the situation is like on Android.
I don't know if it works well with Duolingo, but there's an iOS app called Klavaro which installs an Esperanto keyboard complete with predictive suggestions.
