Question

1. It is five stops from here.

(What does 'it' refer to? Is 'for' missing before 'five stops'?)

2. That makes two of us.
(What is the meaning of this expression?)
A: I don't like this movie at all.
B: That makes two of us.

Answer 1

1. "It" must refer to the bus stop (or train stop) where the speaker wants to get off ... his/her destination. The word "for" is not needed.

2. "That makes two of us" is an idiomatic expression that basically says, "I agree with you." (you + I = two)

A and B are correct.

Answer 2

"It" in this case refers to whatever the topic was that y ou were talking about. It could be a word, situation , etc.

Again "that" is a general term like "it."
