中考临近，Tom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 Mr. Green,
I’m sorry to trouble you. You know there will be a/an    1  exam this term. But it seems that everything goes wrong with me. I can’t fall    2   at night and I can’t listen to the teachers carefully. I am always    3   about my grades. I know it is not good to do so, but I can’t control myself.        __________________      4    _____________________________         ? (此空格不限字数)
Write to me soon. Best wishes to you !
Yours,
Tom
