（1）we mustn't buy things we （don't need）和No,I （needn't ）这两个可以互换吗?为什么.
（2）she didn't have to find them .They found her 这里的didn't have to 和needn't have 互换吧.那这句话的言外之意是什么.是她已经去找过了但其实不必要的?
（3）（不必要可以用needn't和don't have to 表示.它的完成时和过去式分别是needn't fave,didn't have to和didn'tneed to） 这句话就是说前面的那个完成时表示的是已经做了,但没有必要.那后面的过去式又表示什么意思呢

（1）we mustn't buy things we （don't need）和No,I （needn't ）这两个可以互换吗?为什么.（2）she didn't have to find them .They found her 这里的didn't have to 和needn't have 互换吧.那这句话的言外之意是什么.是她
1）不可以.前面一句don't need 其实是don't need to buy的省略.没有必要之意.后面一句是有语境的,可以表示 不需要也可以表示没必要的意思.不可随便替换.
2）是她已经被他们找到了,所以不用去找他们了.
3）就是单纯表示没有必要的意思.
最后加一句,感觉你对情态动词的用法不太清楚.其实英语不要太抠某一个词啊什么的意思了,那样会限制自己对其的理解.好好学习,收获更多吧
