“it +be +过去分词+从句” 结构
“it +be +过去分词+从句” 结构
“it +be +过去分词+从句” 结构
你说的“it +be +过去分词+从句”是主语从句.
原先,是由宾语从句变来的:
They say that he enjoys classic music(宾语从句)-----------（主语从句）：It is said that he enjoys classic music.
分析：It （形式主语）is said（谓语） that （主语从句引导词）he enjoys classic music.(真正主语)
以下是常用的相同句型：
It is said / reported / supposed / thought / believed / estimated / known / found / considered / announced + that + 句子.
千万注意：told 不属于这个句型--------It is told (told必须改换成said) that he will come tomorrow.
1. It is said (reported, learned…) that …
该句型中的it 仍是形式主语，真正主语是 that 引导的主语从句。该结构常译为“ 据说（据报道，据悉……）”。
It is said that he has come to Beijing.
It is reported that another man-made satellit...

1. It is said (reported, learned…) that …
该句型中的it 仍是形式主语，真正主语是 that 引导的主语从句。该结构常译为“ 据说（据报道，据悉……）”。
It is said that he has come to Beijing.
It is reported that another man-made satellite has been put into orbit.
2. It is suggested ( ordered, required ... ) that ...
句型和上一个同属一个句型。主句中的过去分词是表示请求，建该议，命令等词时，that 后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为“ 据建议；有命令……）”。
It is suggested that the meeting ( should ) be put off.
It was ordered that we ( should ) arrive there in two hours.
