问题描述:
if there had not been a layer of rock beneath the soil they would have completed the job.
为什么开头 there后面没有was 省略了吗
答
was就是后面那个been
这个句子是过去完成时,所以be动词也相应变化为had been
答
由be,只是人家用了完成时 had been
答
这个是 there be 句型的过去完成时,there had been
答
been 是be的过去分词 加个不就两个be了
加了不对了
答
这里的was并没有省略
这里是过去完成时态,had + 过去分词,这里的been 就是was 变过来的.
所以并不是was省略了,而是时态变了~
答
没有,,been就是
there be句型的 完成时
