今天上午,小区6号楼102室的张大爷的白色小狮子狗雪球在小卖部门口走丢了,张大爷急坏了。你们刚学过写“寻物启事”,请你试着帮张大爷写一则寻狗启事,贴在小区公告栏里。张大爷提供小狗照片一张,联系电话:53319111。

同类型试题
y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
