It is said that 的意思是據(jù)說(shuō),后面絕大多數(shù)情況是加一句俗語(yǔ)或諺語(yǔ),或常識(shí)性的東西.表達(dá)這種意思的時(shí)候,It's said that是很自然而然一起脫口而出的.sb is said to 意思是某人被說(shuō)在干什么.兩者是不存在時(shí)態(tài)上的區(qū)別...兩者時(shí)態(tài)如何轉(zhuǎn)換呢？就是將It's said that與sb is said to相互轉(zhuǎn)換，時(shí)態(tài)怎么變。最好多給幾個(gè)例句。兩句子轉(zhuǎn)換的時(shí)候，時(shí)態(tài)是保持不變的。一般現(xiàn)在時(shí)態(tài)轉(zhuǎn)換：it is said that he is a good student.=He is said to be a good student.=People say that he is a good student.一般過(guò)去時(shí)態(tài)轉(zhuǎn)換：It is said that he slept late last ninght.=He is said to sleep late last night.現(xiàn)在進(jìn)行時(shí)態(tài)：It is said that she is reading books =she is said to be reading the books現(xiàn)在完成時(shí)態(tài)：It is said that she have finished her homework ,=she is said to have finished her homework 當(dāng)it is said that 句型中有isam are 的時(shí)候后面的就為 sb is said to be 當(dāng)it is said that 句型中是動(dòng)詞時(shí)不管是不是過(guò)去式后面的sb is said to 只能接動(dòng)詞原形
