Răspuns:
1. noticed, took, tried
2.was looking, found
3.were wondering, became
4.were making, started
Explicație:
Sunt cateva reguli pentru past continuous:
1. Daca in propozitie ai "While Subject Verb, Subject2 Verb2." atunci Verb si Verb 2 sunt la past continuous.
2.Daca ai When, unul e la past continuous si celalalt la past simple.
3.Mereu actiunea cea mai lunga e la past continuous (ex. "was making", nu "entered")
Sper ca te-am ajutat :)
