问题描述：
Do you know where Mary is?I couldn't find her anywhere.She____have gone far,for her coat's
接上面 for her coat's still here
A shouldn't B mustn't C wouldn't D can't
我一看到这些否定词就有点蒙,不知道要选哪个,
答
D 选择 D，can‘t have done 对过去事情的猜测
其他的都不存在 这种意思 建议参看语法书
答
A shouldn't 表示不应该做某事
B mustn't 表示禁止做某事
C wouldn't 表示主观不愿意
D can't 表示推测,所以这里用D
