the gaoler looked on eagerly,anxious to see if his fellow actor had at last learnt his lines..这句话的主干是什么?
主干是the gaoler looked on eagerly
anxious to see if his fellow actor had at last learnt his lines..
是形容词短语作状语.
most cars remains suspicious of humans all their lifes.这里的 suspicious of （adj+prep)做什么成分,整个句子是主系表,还是主谓宾?
是主系表结构,因为remain在这里是系动词.

第一句话的主干是：The gaoler looked on ,后面的anxious 引导的句子是一个补充说明，实则为独立主格结构，绝对不是宾语。
remain 后面的成分是表语，表语一般由形容词充当。

the gaoler looked anxious
