she had just resumed a normal pace and had just skirted the foot of a little hill, when she saw two or three villagers hurrying towards her…

skirt v. 绕着…的边缘

问题一

just…when…可以算于一个句型吗？还是说这里just只是一个修饰词

问题二

上文的是这个意思吗 just adv.刚刚，勉强，差一点就不   表示刚绕过一座山(有完成的意思)？

问题三

如果是she was just skirting the…hill, when she saw…   just就是“眼下，现在”的意思了吧
