Good! Here's what I think is unusual with your translation: Every day I pass by the alley, I will find lots of rubbish at the alleyway. --> Every day I pass by the alley, I find lots of rubbish. One day there appeared a few words on the wall -->One day a few words appeared on the wall payed -->paid but even this did not function -->but even this did not work Thereof since the sixth day there hadn't been -->Since the sixth day there hasn't been Here's my translation: Every day I walk through that alley. People always throw trash at the front of the alley, so one day a sign appeared on the wall: “Please don’t litter.” Trash still piled up, so on the second day, that words changed: “It is prohibited to litter here.” Trash still piled up, so on the third day the words changed to: “Penalty of 5 Yuan for littering.” Trash still piled up, so on the fourth day the words changed to: “Penalty of 100 Yuan for littering.” Trash still piled up, so on the fifth day the words changed to: “Litter here and your whole family dies.” The sixth day. No litter at all, even after some time. These are our neighbors: they don’t recognize morals, they don’t recognize authority, they don’t recognize legality, but they finally respect superstition.

In your example, "as if" means the speaker does not believe something will happen. "B" does not believe Bob will get a pay raise. Here's another example. A: I think Cindy will ask John out on a date tonight. B: As if! Cindy likes Bob!
