高中英语语法 高考二轮复习it考点讲义【精讲版】it作形式宾语和主语典型考题与知识点总结典型形式宾语考题分析 I dont think _ possible to master a foreign language without much memory work.A. this                        B. that                        C. its                        D. it分析此题的选项A，B都容易误选。其实此题应选D，主要考查形式宾语 it 的使用。一般说来，形式宾语it主要用于以下句型：动词it宾语补足语真正的宾语。其中的动词通常是 think，find，feel，believe，take，consider，make 等；其中的宾语补足语通常是形容词，有时是名词；而其中真正的宾语通常是比较复杂的成分(如不定式、动名词、从句等)：We found it difficult to persuade her. 我们发现很难说服她。He makes it a rule to get up before dawn. 他习惯于天亮前起床。We found it an easy thing to get along with him. 我们发现与他相处很容易。I think it very strange that he goes out walkingalmost every night. 我认为他几乎每晚都出去散步是很奇怪的。有时可在用作宾语的不定式前加上介词 for / of短语：People felt it impossible for man to fly into the outer space some years ago. 几年前，人们觉得人不可能飞入太空。I dont think it wise for of him to choose such a difficult subject. 我认为他选择这样难的学科是不明智的。典型形式主语考题分析 Is _ necessary to complete the design before National Day?A. this                        B. that                        C. it                        D. he分析此题应选C，其余各项均有一定的干扰性。这里主要考查形式主语it的用法。一般说来，当主语是比较复杂的成分(如不定式、动名词、从句等)时，通常在句首使用形式主语 it，而把真正的主语放在后面：Is it necessary to tell his father everything?有必要把这一切都告诉他父亲吗?It is wrong to say anything like that on that occasion. 在那种场合说那样的话是错误的。Its no good sitting up too late. 熬夜没有好处。Itll be wonderful lying on the beach all day. 整天躺在海滩上该是多么妙啊!It is quite clear that he has read the book. 很显然，他读过这本书。Its a problem where we could get so much money. 我们到哪里去弄这么多钱，这是一个难题。有时可在用作主语的不定式前加上介词 for / of短语：It is very kind of you to say that. 你这样说，真是太好了。It is important for us to keep the balance of nature. 我们要保持生态平衡，这点很重要。先行词it的几类句型 先行词it在主语或宾语的位置，真正的主语或宾语是后面的不定式、动名词或名词性从句。一、作形式主语主要用于It is+ adj. /n. + doing/to do/从句句型。Is it necessary for me to do so? 我有必要这样做吗？It is silly of him to do so. 他这样做真是可笑。Its no good waiting here. 在这里等没有用。Is it certain that they will win? 他们一定会赢吗?Its my duty to help you improve English. 帮助你们提高英语水平是我的职责。注意：与it作形式主语的句型易混的句型。It is known to all that the earth goes around the sun. 众所周知，地球围绕太阳旋转。As is known to all, the earth goes around the earth.It is difficult to persuade him to stay. 劝服他留下来很难。What is difficult is to persuade him to stay. 困难的是要劝服他留下来。二、作形式宾语1. vt.
