A divided by B ...表示被动概念吗?
Five multiplied by three is / eauals fifteen
Six divided by two is / equals three
这两个是很常见的说法,请问两个句子中的.
multiplied by ,divided by 是可以看做是 过去分词 这里表示被动吗?
有说是,过去分词,作定语的.我觉得 不算是定语吧.
倒是觉得 能看作是 省略的 被动语态吧?
Five ( is ) multiplied by three is / eaquals fifteen
Six (is) divided by two is / equals three
请大家说说,这里属于什么语法概念.
