为什么用weighed不用to be weighed?请分析一下句型或语法.
答
have +物名词+过去分词， 是英语中的一种使动用法，表示“让人做某事”
--I'd like to have this package weighed。意思是：我想找人称一下这个包裹的重量。
答
have sth done是一个固定搭配，是说把sth给done了，习惯用法，所以不用to be weighed
答
have sth done是一个固定搭配:请某人做某事,是某事被做,主语是我,而不是package,所以不用to be weighed

The desk needed to be repaired.
答
have sth done 的句型 表示完成某事
