1.B 这个must不是表示推断,If you must know算是一种常用的说法,意思是:如果你一定要知道的话.
2.C 用must提问,回答一定不能用mustn't ,也不用D这种说法回答,要用needn't 或don't have to.

D would有表示推测的意思
Cmust提问的句子,回答不能用mustn't ,可用needn't 或don't have to

第一题:C 如果你要认识,他是卡拉尔,我妹妹的一个朋友
第二题:C 因为must的否定词是needn't,而needn't=don't have to 所以选C,must一般语气生硬。

1, D.would
2, B.don`t

d
b
