中考临近，Torn经常很烦闷，晚上睡不着，上课注意力不集中，经常想着万一考不上怎么办？于是他给某报社的心理医生Mr. Green写了一份e-mail进行咨询，希望他能给自己一些建议，以便在冲刺阶段能全力以赴。
Dear M. Green,
I’m sorry to trouble you. You know there will be a big exam this term. But it seems that everything goes wrong with me. I can’t fall asleep at night and I can’t listen to the teachers carefully. I am always worried about my grades. I know it is not good to do so, but I can’t control myself. What should I do?
Write to me soon. Best wishes to you!
Yours,
Tom
