Question

That is the only way we can imagine to reduce the

That is the only way we can imagine to reduce the overuse of water in students' bathrooms请帮忙分析一下句子结构，谢了。

Answer 1

此句为复合句。

主句是 主系表结构，即：That is the only way.

追答

we can imagine to reduce the overuse of water in students' bathrooms
是定语从句，做后置定语修饰主句表语the only way

关系代词 that (被省略) 代替先行词 the only way，在该定语从句中充当 imagine 的宾语。

完整的定语从句如下：
we can imagine (the only way) to reduce the overuse of water in students' bathrooms.

该定语从句中，we 是主语，can imagine 是 谓语，the only way 是宾语

而 to reduce the overuse of water in students' bathrooms 是 不定式短语做后置定语，修饰 宾语 the only way
固定搭配 the way to do sth 做某事的方法

句子翻译如下：
那就是我们所能设想出来的减少学生浴室/厕所中水资源过度使用的唯一一个办法。

Answer 2
