题目

Loved you will never have to be alone主语是?
唯美句子看到的…句子成分看不懂求解释…顺便解释为什么可以这么用

答案

Loved you will never have to be alone.
You will never have to be loved alone.
此处为表语提前,例如：
Cruel and selfish might be,but diligent and intelligent,he is still our monitor.此处cruel and selfish即为表语提前.
Child as he is,he can swim better than many adults.child为表语提前.
