I t is said 句式人做主语的时候用to do 形式就比如sb is said to be doing,可是如果比如用see这个动词来做的话,却只是在see sb do转变为倍动态的时候用to do ,sb is seen doing就不要的,这个有什么规律么

I t is said 句式人做主语的时候用to do 形式就比如sb is said to be doing,可是如果比如用see这个动词来做的话,却只是在see sb do转变为倍动态的时候用to do ,sb is seen doing就不要的,这个有什么规律么 What I said is right 是主语从句吗?不是要一个句子做主语,才叫主语从句吗?What I said ,貌似不是个完整的句子呀.What I said ,翻译成中文就是 我说的话，这明显不是句子啊。 what he said is true what 又做said宾语?what he said is true what he said 是主语从句,这里what 引导从句,said 的宾语是不是what? 分析一下句子中的it：I can't help it if …I can't help it if he is always late.it做的是形式主语还是形式宾语，后面的是主语还是宾语？ he said it doesn't matter if I made mistakes是什么从句有谁知道的,书上写是主语从句, ___ he said is right.这个要空要填what..为什么呢?拿HE SAID 做主语不可以吗?WHAT HE SAID做主语有什么原因吗? 改写为用形式主语的句式 The boy doesn t shout to the old man.He is polite 开头是 It is 一般现在时的基本句式变化如题,举例:现在进行时的基本句式变化：肯定句式：主语+be( am,is,are)+现在分词+其它.否定句式：主语+be(am,is,are) +not +现在分词+其它.一般疑问句：Be(am,is,are) +主语+ Albert Einstein once said :that only love is the best teacher .that是不是引起主语从句?能不能去掉that,去掉应该怎么改 或者说 去掉that这句又是怎么样的句式?（2）I think that as well . Somethings,I don't say,I don't ask,don't mean I don't care. 语法有毛病吧don't mean I don't care.没主语啊。somethings 也不能做这个的主语 this is the book which i got yesterday分析句子成分.判断句式.this is the book which i got yesterday主语：this 系词：is 表语：the bookwhich i got yesterday 做the book的定语.这个句子是定语从句,我分析的对吗? what 引导的主语从句作主语时,谓语的数由后面的表语或宾语确定.例如：What she said is correct.谓语单复数不应该由What she said 主语确定吗?为什么是后面? 动词ing+反身代词做主语的句式请问,Absorbing himself in reading,he didn't notice the teacher coming 是什么语法现象, 这句话怎么理解?Don't you dare tell her what I said!这是什么句式,祈使句么?请从语法的角度解释一下, I don't think it was Tom who said it ,______?A didn't he B wasn't it C don't I D doesn't it强调句做从句时的反义疑问句怎样解答 特殊疑问词who当它后面的部分可以做主语时,最好用哪个做主语?比如说,Who is the winner?最好说I am.还是The winner is me? whoever says that is a liar 与 who said that is wrong 为什么要这么用?“who said that is wrong” 中 that是主语吗?who又是做什么成分?whoever与who 的具体区别! 主语从句和强调句式 不知道主语从句里面的it is+形容词 和强调句式里的 it is +形容词有什么区别.
