轴的交点．【答案】见试题解答内容【分析】（1）转化为求方程组，然后通过消元化为一元二次方程，通过判断一元二次方程的根的判别式，即可判断抛物线与直线的交点情况；（2）分两种情况讨论：①当函数为一次函数时，与x轴有一个交点；②当函数为二次函数时，利用判别式△＝0，转化为方程即可解决问题．【解答】解：（1）a＝1时，y＝x2﹣2x﹣3，∴{y=x―1y=x2―2x―3，∴x2﹣3x﹣2＝0，∵△＝9﹣4×1×（﹣2）＝17＞0，∴方程有两个不相等的实数根，∴函数图象与直线有两个不同的公共点．（2）①当a＝0时，函数y＝﹣2x﹣3的图象与x轴只有一个交点（―32，0）；②当a≠0时，若函数y＝ax2﹣2x﹣3的图象与x轴只有一个交点，则方程ax2﹣2x﹣3＝0有两个相等的实数根，所以△＝（﹣2）2﹣4a•（﹣3）＝0，解得a=―1 3．综上，若函数y＝ax2﹣2x﹣3的图象与x轴只有一个交点，则a的值为0或―1

MN=32，设O′P＝OH＝O′M＝x，MH＝OH﹣OM＝x﹣1，求出x=52，由勾股定理得出O′H=O′M2―MH2=2，即可得出点P的坐标为（0，2）；②当点P在y轴的负半轴上时，同理可得O′H＝OP＝2，即可得出点P的坐标为（0，﹣2）．【解答】解：（1）∠A＞∠BDC，理由如下：设CD交⊙O于E，连接BE，如图1所示：∠BEC＝∠BDC+∠DBE，∴∠BEC＞∠BDC，∵∠A＝∠BEC，∴∠A＞∠BDC；（2）∠A＜∠BDC，理由如下：延长CD交⊙O于点F，连接BF，如图2所示：∵∠BDC＝∠BFC+∠FBD，∴∠BDC＞∠BFC，又∵∠A＝∠BFC，∴∠A＜∠BDC；（3）由（1）、（2）可得：当点P是经过M、N两点的圆和y轴相切的切点时，∠MPN 度数最大，①当点P在y轴的正半轴上时，如图3所示：设⊙O′为点P是经过M、N两点的圆和y轴相切的切点的圆，连接O′P、O′M、O′N，作O′H⊥MN于H，则四边形OPO′H是矩形，MH＝HN，∴OP＝O′H，O′P＝OH＝O′M，∵M（1，0），N（4，0），∴OM＝1，MN＝3，∴MH＝HN=12MN=32，设O′P＝OH＝O′M＝x，MH＝OH﹣OM＝x﹣1，∴x﹣1=3 2，∴x=5 2，∴O′H=O′M2―MH2=(52)2―(32)2=2，∴OP＝2，∴点P的坐标为（0，2）；②当点P在y轴的负半轴上时，如图4所示：同理可得O′H＝OP＝2，∴点P的坐标为（0，﹣2）；综上所述，当∠MPN度数最大时点P的坐标为（0，2）或（0，﹣2）．27．（10分）如图示，AB是⊙O的直径，点F是半圆上的一动点（F不与A，B重合），弦AD平分∠BAF，过点D作DE⊥AF交射线AF于点AF．（1）求证：DE与⊙O相切：（2）若AE＝8，AB＝10，求DE长；（3）若AB＝10，AF长记为x，EF长记为y，求y与x之间的函数关系式，并求出AF•EF

Famous actress Qin Yi passed away at age 100 in Shanghai on May 9, 2022. It is a huge loss to the Chinese film industry. Born on Feb 4, 1922, Qin Yi, named Qin Dehe at birth,was one of eight daughters in the family. Qin, a film lover, turned her passion for the silverscreen into a lifelong career.In 1939 Qin Yi first appeared in the film A Good Husband. In 1947, she had her first lead role in Far Away Love, which made her a famous film star. In 1949, she was named with three other actresses as the “Top Four Actresses of China”.After 1949, Qin Yi entered the Shanghai Film Studio, where she created some of the most memorable characters of Chinese women on the movie and TV screens, including Railway Guerrillas, Woman Basketball Player No. 5, Lin Zexu, Song of the Youth and Loyal Overseas Chinese.With the rise of television in China in the 1980s, Qin Yi also appeared in major roles in a variety of TV dramas, winning more popularity. She was presented with the Golden Eagle Award in 1983 for Best Actress for Under the Roofs of Shanghai. From 2008 to 2009 she received three lifetime achievement awards. Qin Yi is the only actor in Chinese history to be given the titles of “People’s Artist” (2019) and “Most Beautiful Fighter” (2019).Qin Yi was a strong person, though her personal life is challenging. Qin took care of her sick husband Jin Yan, who spent the rest of his life fighting against a disease for more than 20 years. Her son, Jin Jie, had a serious mental problem and could not live on his own. Qin looked after him for over 40 years before he died in 2007. She had saved 200,000 yuan for the care of her son, then she donated the mony to the victims of 2008 Wenchuan earthquake.
