Re: Cuando (When) is followed by a verb in the subjunctive mood to express a future event still to happen.

In all the examples, the 2nd clause uses simple future or imperative. I get that these can be used, but does that mean that the present can't be used? Can we say: "Cuando vayas al mercado, compras fruta y verdura.

When you go to the market, buy fruit and vegetables.

This is really a question about one of the quiz questions:

I correctly chose the response “por más que lo intento” ________, no consigo recordar todo el vocabulario.

But would it have been grammatically incorrect to say “por más que intento, no consigo...” ?

In the question "En el viaje ________ un niño atrás", the answer was 'se nos quedó'. Could you give a literal translation of this sentence because otherwise it seems like the verb agrees with the object of the sentence rather than the subject. I guess I'm asking for a way of translating quedar in my head so that even if it makes the English awkward, I can also keep straight subject and object (much like I can substitute "is pleasing" for gustar). 

Thanks! 

Could I say La ultima vez que la vi fue hace...
