We must be careful ,a lion escape from the zoo.这个句式结构应该不对吧?逗号前后都是完整的句子
escape改成escaped

错了, 应改成:
We must be careful , for a lion escaped from the zoo.(for补充说明原因)
/We must be careful as/since a lion escaped from the zoo.(as/since表示已知的原因)
再问：这个题其实使用escape填空，答案给的是escaped ，是不是应该用escaping
再答：可以呀, a lion escaping from the zoo是独立主格结构, 作原因状语.
