My name is Yang Jiani. I am a middle school student in Guangzhou now. I like watching cartoons(动画片)all the time. I really enjoy myself when I'm watching cartoons. But now I don't watch them too often. Why? Because as a middle school student, I have to study(学习)many subjects. So I have to spend more time on my lessons and I study well. Now I only watch cartoons on Saturday or Sunday. And I don't watch them for a long time because it is bad for my eyes. I don't want to wear a pair of glasses at an early age. So I don't watch many cartoons now.【1】Where does Yang Jiani study now?A.In（3分）如图，四边形ABCD是⊙O的内接四边形，∠B=70°，则∠D的度数是（ ）A．110° B．90° C．70° D．50°
