Answer 1

1.trap是陷阱,美洲狮不会攻击人类除非它感到它被设计了.（落入陷阱了）
A虽然有处于困境含义,corner我们可以想象,它是一个三维空间一角,狮子所处的环境没有边界,换句话没有空间限制,从语意上选,感觉B更贴切.
2.to one's surprise 是固定短语搭配.这句话可以这么解读：
To their surprise,They found that the goddess turned out to be.
3.这里的impurity最好去查一下,是否是可数名词,有待商榷.
4.你意思是with in red吗?这里sb.in red就可表示穿红衣服的某人.
5.redder(a.) 红的,红热的.除了比较级,它也有形容词的意思.
6.词组stand at：犹豫不决,踌躇.stand by：v.支持,遵守,袖手旁观,准备行动.eg:她在上船的悬梯下犹豫不决.
