Răspuns:
1. I am at school now
2. We were at the theatre yesterday
3.The children go often in the park
4. They did their homework last evening
.
Explicație:
la 1 este Present simple pt ca avem adverbul de timp ''now'', adica ''acum.
La doi este Past Simple pt ca avem indiciul temporal ''yesterday'' adica ieri, la fel ca la patru unde avem ''last evening'' adica ''seara trecuta''.
Totusi, la patru am pus ''did'' care e forma de Past simple a verbului ''do'', nu ''made''- forma de trecut a verbului ''to make'' pentru ca in mod corect, se spune ''I did my homework'' nu ''i made my homework''.
