我问的是句子分析,it is 是形式主语吗?想知道句子结构it is widely believed there are several positive aspects as follows 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？ it 做形式主语时、句子是主语从句么? it is astrategy that more and more companies are employing我想请教一下这个句子的it 是做形式主语吗?that引导的是主语从句吗?我感觉好像是强调句啊 It is Pat who will do all the work. 句中it是主语吗?那如果出1道题目问我这句句子的主语是哪个，我应该怎么回答？ ？ 请分析主语,谓语,宾语It is the duty of everybody to obey the law.to obey the law是宾补吗it 是形式主语。真正的主语是duty of everybody是duty 这个句子是形式主语句型吗?It is interesting to play with dogs 强调句的主语问题句子如下:it is not simply to raise everyone's job prospects that all children attend school into their teens.这是考研难句分析里的一句,是猛飞江涛写的,我不苟同书,书上说本句典型是it 是形式 l found it important for us to listen carefully in class这里的it我知道是形式主语,而还有个句型是it is adj for sb to do sth,请问有什么区别?第一个句子的形式主语怎么用?在哪用?这个句子的格式是什么? 如何区分it 作形式主语 还是主语像 it is hard to say 这里的it是形式主语吗 还是做句子的主语 是翻译成这个很难说 还是说很困难可是 我认为 这句话的主语应该是人 应该是 I am hard to say it 因为 分析句子成分 It's good for your health to do more sports.这句话中for your health做什么成分?to do more sports 做主语； is 是系动词；it是形式主语； good是表语那么for your health是做什么成分的?句子还原后： it is only because they konw what they are for that thay are working with such admirable zeal.句子意思没有问题,语法上分析不出来it是形式主语,实际的主语是哪部分only because they konw what they are for that 是表语从句 分析这个句子：it isn't easy being the new kid at schoolit isn't easy 是形式主语,being the new kid at school是真正主语.动名词形式和to do形式,都可以用it引导的形式主语吗,二者有没有什么区别? 怎样很快判定it是形式主语(好的追加分)是不是只要前有it后又有不定式的句子都是it做形式主语 If it is convenient I can see you tomorrow.如果明天方便的话,我可以明天见你.考点：用It 做主语.求分析下这个句子的真正主语,以及这个句子的结构.到底是‘I can see you tomorrow’做真正主语还是‘tomorr It is a pity that he could not come .这句话是主语从句吗?请分析一下句子成分,It is unusual for him to be late .这里的it是形式主语，to be late是真正的主语，麻烦分析一下句子成分， it is adj to do句子成分分析to do为真正主语.it为形式主语.也就是说一个句子两个主语么?.那for sb呢? 英语句型分析,高手帮我看看It is determined that cigarette somking is dangerous to your health.It is crucial that we get this information.这两个句子是不是都是以it做形式主语,that 从句为真正的主语结构的句型.It is
