And then I fancy that the daily intimacy with the sick man moved herstrangely. She raised his head to give him food, and it was heavy against herhand; when she had fed him she wiped his sensual mouth and his red beard. Shewashed his limbs; they were covered with thick hair; and when she dried his hands,even in his weakness they were strong and sinewy. His fingers were long; theywere the capable, fashioning fingers of the artist; and I know not what troubling thoughts they excited in her. He sleptvery quietly, without a movement, so that he might have been dead, and he waslike some wild creature of the woods, resting after a long chase; and shewondered what fancies passed through his dreams. Did he dream of the nymphflying through the woods of Greece with the satyr in hot pursuit? She fled, swiftof foot and desperate, but he gained on her step by step, till she felt his hotbreath on her neck; and still she fled silently, and silently he pursued, andwhen at last he seized her was it terror that thrilled her heart or was itecstasy?
请教老师：上面节选中，这一句 and I know not what troubling thoughts they excitedin her.没了解， I know notsth 和 I don't know sth一样的意思吗？麻烦老师剖析一下，谢谢！
早期英语中，动词的否定是直接在实意动词后+not, 而无须借用助动词do。作者在这里用了一种古体。
