병렬 구조에서 look의 형태가 궁금해요

문장에서 look이 try와 병렬을 이루는 건가요?
아니면 try to forget에 이어지는 구조라 to가 생략된 건가요?
“if we try to forget all we have heard about green grass and blue skies, and look at the world as if we had just arrived from another planet on a voyage of discovery and were seeing it for the first time, we may find that things are apt to have the most surprising colors.”
and가 있어서 to부정사로 보기는 어려운 것 같기도 한데 설명 부탁드려요.
