Now we can see a man and his wife at the breakfast table. They are not speaking to each other.
They haven’t spoken to each other at the breakfast table for years. The husband is reading his newspaper. We can’t see his face. The wife looks very worried as she gets a cup of tea ready for him. Today she is using a new kind of tea for the first time. The husband picks up his cup. He isn’t interested. He tastes his tea. Suddenly he puts down his newspaper. Something is different! Can it be the tea? He takes another taste. It’s wonderful. He smiles. He looks at his wife and says in surprise, “Doris, when did you cut your hair?” Doris is pleased. She answers, “Two months ago.” Doris asks, “Herbie, when did your hair begin to become white?” He answers, “A long time ago.” Doris says, “We have been together for many years, but we never cared about each other.” Now they aren’t worried any longer. Breakfast is different. Has a new kind of tea changed their lives?

（2）設(shè)面EBC∩SD＝F，取AD中點N，連SN，設(shè)SN∩EF＝Q．
∵AD∥BC，∴AD∥面BEFC．而面SAD∩面BEFC＝EF，∴AD∥EF．
又AD⊥SN，AD⊥NM，AD⊥面SMN．
從而EF⊥面SMN，∴EF⊥QS，且EF⊥QM．
∴∠SQM為所求二面角的平面角，記為α．……… 7分

（3）存在一點P，使得OP⊥平面EBC．取SD的中點F，連FC，可得梯形EFCB，
取AD的中點G，連SG，GM，得等腰三角形SGM，O為GM的中點，
設(shè)SG∩EF＝H，則H是EF的中點．
連HM，則HM為平面EFCB與平面SGM的交線．
又∵BC⊥SO，BC⊥GM，∴平面EFCB⊥平面SGM． …………… 12分
在平面SGM中，過O作OQ⊥HM，由兩平面垂直的性質(zhì)，可知OQ⊥平面EFCB．
而OQ
平面SOM，在平面SOM中，延長OQ必與SM相交于一點，
