为什么,请详细回答

1.A:The food must be good.B:No,it______be good.
A must not B needn't C wouldn't D cannot
c cannot 是单纯表示主观上认为不可能，而 wouldn't则有从客观角度，有原因的（如时间太长）的不可能

2.I am afraid I_____go with you. I am very busy these days.
A mayn't B can't Cam not able to D mustn't
B 选can't最主要是是最常用的，日常生活用于都是这么用的

3.The soldiers looked everywhere for the spy,but they _____find him.
A can't B couldn't C is not able to D was not able to
B 过去式，只能用couldn't啊， were not able to才符合语法。
