The headmaster said that they would have another library built.的时态和语态
问题描述：
The headmaster said that they would have another library built.的时态和语态
答
从句本应为一般将来时：
they (will) have another library built.
因为主句是一般过去时：
the headmaster (said)
所以从句时态变为 过去将来时：
The headmaster said that they （would） have another library built.
built 是动词build的过去式，在此表被动。图书馆被建造。
答
一般过去时，从句为被动语态
答
主句是一般过去式
从句是一般将来时
因为这是宾语从句
所以从句的时态受主句影响
变成过去将来时
