Pointer 1. Attitude refers to the writer’s opinion/stand about something and tone refers to the way the writer's opinion/stand is revealed in the text.**
Father went on affably, "I know the mosquitoes are biting, but are the fish?"
Here, we can say that the narrator's tone is humorous when he spoke to Mr. Duvitch.
On the Late Show, the host sampled chicken that was dredged in cricket flour and deep-fried to a crisp; he said, with obvious relief, that it tasted “just like fried chicken”. Who would have thought?
Here, we say the writer's tone is sarcastic when he states "Who would have thought?". From this, we can infer that the writer is cynical or that the writer has a cynical attitude towards the way others expect insects to taste bad.
