补足语是什么?

句子（1）分析的正确
句子（2）中的was不是系动词,而是助动词.was seen 是被动语态,是谓语.
playing basketball 是主语补足语.
be动词可以是系动词,也可以做助动词.在be doing进行时中,be done被动语态中,和be going to do将来时态中都是助动词.

2一般都是说was seen是一种被动语态，很少听见有人把was和seen分开说的

两个都对

补足语有主语补足语和宾语补足语：
1.主语补足语即被动语态中的宾语补足语。
eg.They caught boy stealing.

stealing 即为主语补足语
被动语态后的主语补足语
对于主语补足语，语法家们各有不同的看法。...

补足语有主语补足语和宾语补足语：
1.主语补足语即被动语态中的宾语补足语。
eg.They caught boy stealing.
被动语态 The boy was caught stealing.
stealing 即为主语补足语
被动语态后的主语补足语
对于主语补足语，语法家们各有不同的看法。有的把连系动词后面的部分称作主语补足语；有的又把被动语态后的补足语称作表语，与被动语态一起称作复合谓语。笔者通过教学体会到，还是把被动语态后面的补足语称作主语补足语好些。这是因为学生很容易接受“宾语补足语”，而如果把带有宾语补足语的句子变成被动句，原来补充说明宾语的部分就变成补充说明主语了。
宾语补足语：位于宾语之后对宾语作出说明的成分。宾语与其补足语有逻辑上的主谓关系，它们一起构成复合宾语。
