It is said that he often works-------the clock ,without any sleep at all .请问横线处填入什么介词?

It is said____ ____ was all ___ he said.It is said that that was all that he said. It is said that that was all that he said.这三个that分别是什么从句? it is said that that was all that he said= it is said that that was what he said这两个句子相等吗? It is said that. 为什么 It is said that he came.=He is said to have come. it is said that后面用过去式么,It is said that he always play soccer.这句话对么? It Is said that he is ill.改成He is said ___ ___ ___.怎么写?我急死了 英语句子,用的什么语法?It is that that was that he said. 一道选择题：________ been abroad before________ been abroad before. A it is said that he has B they said that he has C he is said that he hasD he is said to have怎么做? Let it not be said that he is bad student.关键是Let it not be said that 为什么是It is said that 而不是It said that 这句话的意思：It is said that he is a hero,but that’s all there is to it. It is said that he was caught.One____so,but in fact he wasn't. 语法：It is said that ____ was all ___ he said.两个空全部填that为什么呢 用词的正确形式填空 it is said that he is had the machine （ ）【check】 It is said believed/known/supposed that he is from Africa.翻译 用 He is said 和 It is said that 造句~要正确的语法~说明中文意思 it is said that的问题it is said that he has recovered...为什么不是it is said that he had recovered...主句式过去时,从句不也要是过去时吗
