the noise had been so faint that no one thought that the ship had been damaged

题目

the noise had been so faint that no one thought that the ship had been damaged
The noise had been so faint请问这句的句子成分和结构。the noise是主语，那谓语呢，had been是过去完成时结构吗？为什么后面不是跟动词过去分词，而是跟了一个形容词，这算是什么结构啊，

答案

the noise had been so faint如果改成一般现在时可能有助于你的理
the noise is so faint （这个声音是如此微弱）
is是系动词,后面跟了一个形容词.这个句子是“主语+系动词+表语”结构.
the noise had been so faint是过去完成时.过去完成时的结构是had+过去分词,be的过去分词就是been.
你问为什么had been后面不是跟动词过去分词,答案是：
“had been+动词过去分词”是被动语态的过去完成时.而主动语态的过去完成时是不要been的,主动语态的过去完成时的结构是“had +动词过去分词”.
