这句话我不是很理解,帮我分析一下句型
for though the pictures were supposed to be the work of famous artists里面的 to be the work of famous artists不是很理解

for though尽管这样
the pictures名词 be supposed(be动词+形容词) to be the work of famous artists(这里则是不定式为了描述被猜想成什么了)
suppose 正常是用suppose sb to do sth 例子I suppose him to be about fifty.
然后被动的话就是He is supposed to be about fifty了
同理还有He is capable(形容词) to work out this problem(不定式修饰 capable什么东西).the pictures were supposed这段话不是被动语态吗?其实被动语态的 动作的过去分词 都可以当做形容词来看被动语态就是be+adj的一种比如supposed 去查字典,字典的意思就是adj. 假定的;被信以为真的;想象上的killed adj. 被杀死的;镇静的;隔开的pickedadj. 采摘的;精选的
