求解一道有关时态和固定用法的SAT语法题
Prior to invention of the printing press in 1400s,the only way (to produce) duplicates (of) books (has been) to have copies (handwritten) by professional scribes.
因为出现1400年,要讲后面的has been改为过去式had been
我想问一下1 had been to have copies 是什么用法
2 handwritten是形容词 修饰have的话应该是变为副词啊 如果是修饰copies的话 形容词可以放在名词后面么

因为有短语介词Prior to
表示在过去某个时间之前
所以谓语用过去完成时 表示过去的过去
1 had been to have copies 是动词不定式短语作表语 表示抽象概念 相当于名词作表语
用法 没有问题 had been是系动词be的过去完成时
2 handwritten是过去分词具有形容词或副词特征 这里应该是作宾补
这是have sth done 句型

根据句意义,前面一句的叙述是过去时,had been发生在过去的过去,copies与handwritten是一种被动关系,即have something done的结构,故用过分。

OK 我来给你解释一下
问题一:to have copies是动词不定式作表语,举个简单的同类句子就是My job is to teach you。我的工作就是教你。
问题二:handwritten这里面不是形容词,而是handwrite 的过去分词,我想这回你就懂了吧
如果满意请你采纳!!谢谢has不能当系动词 to have怎么能当表语呢可是has 后有been 啊,b...
