it is said that 什么时态

it is said that 什么时态 it is said that后加什么时态 it is said that kind of animal_____(disappear) millions of years ago用什么时态,Y 有没有it was/had been + said that +从句这种结构若有的话那从句的时态用什么还是只有it is said that这种 it was(is) ...that+什么时态 It is said that. it is said eport...that与sb is said eport..to的区别两个句型转化之间有什么异同,主要是时态区别. it is said that后的从句用什么时态是固定的吗还是?例如It is said that the food at the restaurant ___（taste） quite berrible是tastes 为什么 关于it is said that我看到有这两个句型：it is said that...it has been said that...我想问1.这两个句型有什么区别吗?也就是说 会因时态不同 而使用范围也不同吗?2.从句的时态有规定吗?我看到的例句从 it is said that when her boss is away he__the manager of the corporation.(act as)act as应用什么时态?为什么? It is reported that后要用什么时态过去完成时还是一般过去时 it is hign time that 后用什么时态 It is said that…时态问题,It is said that…据说…… It is reported that…据报导…… 如果是过去说或过去报道,还是It is ...会不会变成It was. it is said that后加什么词 为什么是It is said that 而不是It said that it is to say that 和it is said that 有什么区别? It is said that that that that that man said is not that thatthat that woman said.翻译 it is said that用法在过去·现在·将来时态的一般形式顺便将sb.is said to 一般形式讲下（从句）
