1. how can we make use of the material 你假设的是make use of 是个动词短语固定用法,"利用"
2. what use can we make of the material 里的of 改成for, use 值得是用处,这里值得是见朗文释义"find a use for sth." 虽然很想用from,但是for才是标准.
3, the material can be made use of by us可以,指的是利用,加上个good方便你理解
the material can be made good use of by us, of可以放在句首
4. a use或者uses for the material can be made by us, 同样,for可以放在句首,use 是用途
5. how can the material be made use of? 没错还是短语 make use of 利用 的使用.
6. what use can be made of the material 中of 改成for use 表示用途
7. what use of the material can be made of of 改成for跟第六句意思一样,都是把use当做用用途来看
