对话精讲
1、地道表达
【地道短语】
twist and turn
【解词释义】
twist和turn都有“转身，改变方向”的意思。该习语的动作破像人失眠时在床上好做的动作，所以用它指“辗转反侧，难以成眠”。
【支持范例】
Unable to sleep,the patient twisted and turned in his bed.
病人在床上辗转反侧，不能入睡。
He twisted and turned in bed with a high fever.
他因为高烧在床上辗转反侧。
All that night I kept thinking of it, twisting and turning.
我当晚辗转反侧，一直不停地想着那件事情。
