Question

英语语法
lined up against the wall,there were long thin wires attached to metal sphere .这里lined up against the wall的逻辑主语是什么,能不能还原为一个从句?

Answer 1

lined up against the wall的逻辑主语是long thin wires
还原成从句可以写成,There were long thin wires that were lined up against the wall attached to metal sphere.
这样没有语法错误,但会感觉赘述一些.
如果不一定要There be 句式的话,可以写成：
Long thing wires,which were lined up against the wall,were attached to metal sphere.
