it作形式宾语I find it hard to get along with herI find it is hard to get along with her第二种对吗可以吗?为什么会省去is?

请问find feel等词后有宾补时,用it作形式宾语, it作形式主语和作形式宾语的区别如：I find it necessary to take exercise every day.I find it's necessary to take exercise every day.I find that is necessary to take exercise every day.这三句语法对吗?it作形式主语和作形式 i find it difficult to achieve this goal中的it是作什么成分.形式宾语吗?i find it is difficult to achieve.这句话是对的吗. 作宾语．不定式短语作宾语时,如果还带有宾语补足语.往往把不定式宾语放在宾语补足语之后,而用 it作形式宾语．例如：He wanted to go． 这个不定式做了宾语,哪里是谓语I find it interesting to stud it作形式宾语I find it hard to get along with herI find it is hard to get along with her第二种对吗可以吗?为什么会省去is? it作形式宾语的例句 Did you find ____ hard to learn English?A、it B、it was C、it is D、Both A and b尽管有it作形式宾语的用法,但it引导形式主语作宾语又未尝不可, I think it +adj+to do it作形式宾语 I think it's +adj+to do it作形式主语我知道两种形式都可以,但是我总是搞不清楚,什么情况下使用哪一个,请列举,I find it adj+to do sth也有啊, 形容词作宾补1.比如像这样分析：I做主语,find作谓语,it作……（形式宾语?宾语?）important作（宾补?）to learn English作（宾补?还是说important to learn English全都是宾补?我对I find it这个句型一直没太 it作形式宾语的宾语从句常见动词有 I think it is wrong to tell lies.is wrong作什么句子成份?it 作形式宾语 is wrong 作宾语补语吗? I find it hard to get along with her.形式宾语能不能改成I find it‘s hard to get along with her.为什么 It作形式宾语It做形式宾语的格式是什么?是不是it+be+adj.+to do?为什么教科书有一个句子是“I find it difficult to remember everything.”这里为啥没有Be动词?可有可无麽?不是形容词前都要加Be动词的麽 改为宾语从句 用it作形式宾语I took that for granted.They woule promise what they had promised. 在i can it( )it.中find用什么形式 it作形式宾语的句子有哪些? it 可作形式宾语吗?如果可以,请举例说明. appreciate的为什么要带it作形式宾语
