形式主语形式宾语专项练习
形式主语形式宾语专项练习形式主语和形式宾语是英语语法中的两个重要概念。
在句子中，形式主语和形式宾语可以代替真正的主语和宾语，使得句子结构更加清晰。
需要注意的是，在使用形式宾语it时，不能使用that、this等词语来代替。
通常情况下，宾语补足语会位于形式宾语之前，而真正的宾语则会放在句子末尾。
例如，I find it difficult to do the job well.（我发现做好这件事不简易。
）和I think it best that you should stay here.（我认为你最佳住这儿。
）等。
形式宾语通常后面跟着宾语补足语和真正的宾语，但也有一些例外情况，例如当不定式、动名词或从句在复合宾语结构中作为某些动词的宾语时，或者某些表示“喜、怒、哀、乐“的动词后面不能直接接宾语从句时。
需要注意的是，that引导的宾语从句不能直接作为介词的宾语。
Would you make sure that she arrives home early?He maintained his innocence.___。
if the object clause serves as the object of the verb。
"it" should be used.For example: I leave it to your own judgement whether you should do it.We have you to thank for ___.It's easier to say than to do.It takes me 30 minutes to bike to school every day.It's not easy for us to learn a foreign language.Children find it ___.Do you think it's important to play computer games well?Is it ___ the design before nal Day?I don't think it's possible to master a foreign language withouta lot of memory work.8.Does it matter if he can't finish the job on time?9.___'___ him to work harder。

八年级英语形式主语练习题20题含答案解析
八年级英语形式主语练习题20题含答案解析1.It is important for us to learn English well.A.for usB.to usC.of usD.with us答案解析：A。
“It is+形容词+for sb to do sth”表示“对某人来说做某事是……的”，用介词for，表示对于某人来说某事的性质。
of 一般用于表示人的品质、性格等的形容词后。
to 和with 在此结构中不恰当。
2.It is necessary that we arrive at school on time.A.arrive atB.get toC.reach toe to答案解析：B。
arrive at 和get to 都表示“到达”，reach 是及物动词，后面直接跟地点，不用加to。
come to 也有“来到”的意思，但在此处表达“到达学校”不如get to 准确。
3.It is fun to play basketball after school.A.playB.playingC.to play答案解析：C。
“It is+名词+to do sth”，这里用动词不定式to play 做真正的主语，it 是形式主语。
play 和plays 不能做主语，playing 一般在特定的句型中才做主语。
4.It is easy for me to solve this math problem.A.for meB.to meC.of meD.by me答案解析：A。
“It is+形容词+for sb to do sth”，用for 表示对于某人来说某事的难易程度等。
of 一般用于表示人的品质的形容词后，to 和by 在此处不恰当。

2014-2015初中英语形式主语和形式宾语专项练习（有答案）形式主语或形式宾语指的是：当不定式(短语)、动名词(短语)或从句在某个句子中作主语或宾语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语或形式宾语置于句首或句中动词之后，而将真正的主语放在句尾。
此时it只起先行引导作用，本身无词义。
主要有:一、it作形式主语It 作形式主语的常见句型：①It + be + 形容词+ to do sth. / doing / that ….e.g. It is very important to learn a foreign language. (学一门外语非常重要。
)It is useless crying over the spilt milk. (覆水难收。
)It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。
)②It + be +名词词组+ doing / that ….e.g. It is no good telling lies. (撒谎没好处。
)It is a pity that you didn’t go to see the film yesterday.(你昨天没看成那部电影真遗憾。
)It is a truth that there would be no new China without the CommunistParty.(没有共产党就没有新中国，这是毋庸质疑的。
)③It + be + 过去分词+ that ….该句型常见动词有：say, hope, think, suppose, expect, report, know, believe,decide, etc.e.g. It is said that they have invented a new type of computer.(据说他们发明了一种新型电脑。
)It is believed that China will become one of the strongest countriesin the world.(大家都相信中国将会步入世界强国之列。
)It was reported that more than 170 thousand people died in the 2004tsunami.(据报道，至少有十七万人在20XX年那场海啸中丧生。
)④It + seems / appears / happens等不及物动词+ that ….e.g. It seems that he enjoys pop songs very much. (似乎他非常喜欢流行歌曲。
)It appears that Tom might change his mind. (看来汤姆可能会改变主意。
)⑤若句子是疑问形式，就只能用it作形式主语。
e.g. Does it matter much that they won’t come tomorrow?(他们明天不来很重要吗？)Is it true that he will go abroad next week? (他下周出国是真的吗？)⑥It + takes + (sb.) + some time + to do sth.这是一个表示“(某人)花多少时间干某事”的句型，其中it是形式主语，代替后面的不定式(to do sth.)，句型中的sb.也可以省略。
e.g. It took me some time to read the reading materials(我花了一些时间才读完那段阅读材料。
)It took him fourteen hours to go to NewZealand from Shanghai byplane.(从上海乘飞机去新西兰花了他14小时。
)How long does it take you to go to Beijing from Qingdao by train?(从青岛坐火车到北京一般要花多久时间？)I am not sure, but I think it takes at least nine hours to get there.(我不能肯定，但估计至少要九个钟头才能到那儿。
)二. it作形式宾语在句中,通常会在宾语补足语前使用形式宾语it，而将真正的宾语移至句末，其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”：I find it difficult to do the job well. 我发现做好这件事不容易。
I think it best that you should stay here. 我认为你最好住这儿。
We think it no use complaining. 我们认为抱怨是没有用的。
通常意义的形式宾语其真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形，即用于“动词+it+宾语补足语+真正的宾语”这样的结构，但以下几类形式宾语却比较特殊，其后没有宾语补足语。
①当不定式(短语)、动名词(短语)或从句在复合宾语结构中作某些动词的宾语时(如think, make, find, consider,feel, suppose等)；e.g. They found it pleasant that they worked with us Chinese.(他们发现与我们中国人一起工作很愉快。
)I don’t feel it difficult to understand the Special English.(我觉得理解英语特别节目并不难。
)He makes it a rule never to borrow money. (他立志决不向别人借钱。
)I think it no need talking about it with them.(我认为没必要跟他们谈。
)②某些表示“喜、怒、哀、乐”的动词，如like, enjoy, love, hate等，往往不能直接接宾语从句；e.g. I don’t like it that he’s so lazy. (我不喜欢他那么懒惰。
)I hate it when my mother asks me to eat eggs. (我讨厌母亲要我吃鸡蛋。
)③that引导的宾语从句不能直接作介词的宾语；e.g. You may depend on it that we shall always help you.(尽管放心，我们会随时帮你的。
)Would you see to it that she gets home early? (你负责保证她早到家，好吗？)He insisted on it that he was innocent. (他坚持说自己是无辜的。
)④由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。
e.g. I leave it to your own judgment whether you should do it.(我让你自己判断这事是否该做。
)We owe it to you that there wasn’t a serious accident.(多亏了你才没有发生严重事故。
