在课文第147页，有一句，
The man broke the bones and his sucked and chewed on them like an animal.
他敲开了骨头，像一只野兽似的吮吸着、咀嚼着。
那个人在一块骨头上咀嚼，那神情肯定是，仔细，认真，于是，英语的chew on就有引申义：仔细考虑，深思熟虑，好好想想，也就是 “在做出决定之前仔细考虑某事”，例如：
I've been chewing on the job offer for days, but I still haven't made a final decision.
一连几天我都在考虑这个工作机会，但依然没做最后的决定。
We'll chew on your suggestion.
我们会仔细考虑你的建议。
