大仙念动咒语,噀(xùn,含在口中)一口水,喷在脸上,随即解了睡魔。二人方醒,忽睁睛,抹抹脸,抬头观看,认得是仙师与世同君和仙兄等众,慌得那清风顿首,明月叩头道:“师父啊!你的故人,原是‘东来的和尚,——一伙强盗’,十分凶狠!”
明月为何称师傅的故人是“一伙强盗”?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
