Answer 1

It's a different word depending on the context:

'As we walked through the hall, all eyes turned upon us.' = "MIENTRAS caminábamos por el corredor, todos los ojos nos seguían".

'He looked at me as if I had just reproached him!' = Me miró COMO si yo lo hubiera acusado"

'His eyes are as blue as ocean water.' = Sus ojos son TAN azules COMO el agua del océano.

'Her expression looked as angry as my mother's usually is!' = Su expresión pareció TAN enojada COMO suele ser la de mi madre".
.

"como si"= as if
