Unit 5　A delicate world 语法专项指导 it作形式宾语 语法原句再现 ①No visitor would think it surprising that the island is a UNESCO World Heritage Site. ②Experts felt it necessary to come up with a plan to remove all the rabbits from the island. ③This incident made it clear that the rat,mouse and rabbit problem needed solving once and for all. 通过观察上面3个句子可知,句中的it充当了形式宾语。还有哪些情况下it也作形式宾语呢? 语法知识点拨 核心知识点拓展：it作形式宾语的3大结构深度解析 结构1：动词 + it + 宾补 + 真宾语 核心公式：V. + it + adj./n. + to do/doing/that从句 高频动词：think, find, feel, make, consider, believe 宾补形式：adj. (important) / n. (a pity) 例句：We take it our responsibility to protect the environment. 易错点：不可省略it直接加真正宾语。 结构2：喜恶动词 + it + 状语从句 核心公式：V. + it + when/if 从句 高频动词：like, dislike, hate, enjoy, appreciate, prefer 例句：I appreciate it if you can join in the activity. 关键点：此类动词后接状语从句时，必须用it作形式宾语。 结构3：动词短语 + it + that从句 核心公式：V. + prep. + it + that 从句 高频短语：rely on, depend on, insist on, see to, count on 例句：We can count on it that he will help us. 关键点：“动词+介词”短语后接that从句时，it不可省。 1.7.2013 同学们，我们来深入学习it作形式宾语的三大核心结构。首先是最基础的“动词+it+宾补+真正宾语”结构，这里的真正宾语可以是不定式、动名词或从句。记住，it是必不可少的，不能省略。第二种结构是“喜恶动词+it+when/if从句”，当like, hate这类词后面接从句时，必须用it作形式宾语。第三种是“动词短语+it+that从句”，特别是由动词和介词组成的短语，后面接that从句时，一定要加上it。掌握这三种结构，就能应对大部分相关题目了。 ‹#› 易混点辨析：it作形式宾语 vs it作形式主语 it 作形式宾语 (Object) 核心结构：主语 + 谓语 + it + 宾补 + 真正宾语 位置特征：it 位于谓语动词之后 核心目的：避免宾语过长，保持句子平衡 We find it important to protect animals. it 作形式主语 (Subject) 核心结构：It + 谓语 + 真正主语 (to do/that) 位置特征：it 位于句子开头 核心目的：避免主语过长，突出核心内容 It is important to protect wild animals. 辨析小技巧： 看 it 的位置 + 是否有宾补（形容词/名词）。有宾补则为形式宾语，无则大概率为形式主语。 1.7.2013 在学习it的用法时，很多同学会混淆形式宾语和形式主语。这张表格清晰地展示了它们的区别。首先看位置，形式宾语it在谓语动词后面，而形式主语it在句子开头。其次看结构，形式宾语后面通常会有一个宾语补足语，也就是形容词或名词，而形式主语后面直接跟真正的主语。记住这个小技巧，就能轻松区分它们了。 ‹#› 特殊情况补充：it作形式宾语的3个高频特例 想当然认为 结构：take it for granted that + 从句 例句： Some people take it for granted that nature will always provide us with everything. 说明：it为形式宾语，that从句为真正宾语。 归功于某人 结构：owe it to sb that + 从句 例句： We owe it to the scientists that many rare animals are saved from dying out. 说明：it为形式宾语，that从句为真正宾语。 动名词作真正宾语 结构：it + 宾补 + doing (少数动词) 适用动词：find, think, consider, feel 例句： I think it useless complaining about the environment without taking action. 1.7.2013 除了基本结构，还有几个特殊的固定搭配需要我们牢记。第一个是“take it for granted that”，意思是“想当然地认为”。第二个是“owe it to sb that”，表示“把某事归功于某人”。第三个是关于动名词作真正宾语的情况，要注意只有少数动词后面可以这样用，比如find, think等。这些固定搭配在考试中经常出现，大家一定要记牢。 ‹#› 记忆口诀 核心记忆口诀 动词后接宾补现，it代宾语放前面； 喜恶动词接状从，it架桥在中间； 动介短语接that句，it不可丢一边； 固定搭配记心间，take/owe it是关键。 1.7.2013 为了帮助大家更好地记忆，这里有一个口诀，大家可以记一下。同时，我们还补充了几道近几年的高考真题，大家可以看看高考是如何考查这个知识点的。通过这些真题，我们可以发现，it作形式宾语是一个高频考点，大家一定要熟练掌握。 ‹#› 1.当复合宾语中的宾语是不定式、动名词或宾语从句时,往往用it作形式宾语,把真正的宾语放在它的补足语后面。常用于此结构的动词有feel、consider、find、believe、make、take、imagine、prove、think、suppose、regard、notice等。 I find it not easy to improve one’s oral English. 我觉得提高英语口语不容易。 He made it clear that he would stick to the end. 他明确表示他会坚持到底。 语境运用 句子语法填空 ①We all regard 　　　　 our duty to help those in need.  ②I think it very interesting 　　 　　 (learn) English.  it to learn 2.当主句的谓语是表示喜恶的动词,如like、dislike、hate、enjoy、appreciate、prefer等,且后面有when/if引导的从句时,一般把it放在主句的谓语动词后面,再接从句。 I’d prefer it if I didn’t have to do so much work. 要是我不必做那么多工作,那就太好了。 翻译句子 ①如果您能考虑我的申请,我将不胜感激。        I would appreciate it if you could take my application into consideration.　 语境运用 ②我讨厌人们在公共场所吸烟。     I hate it when people smoke in public places. 3.rely on、insist on、stick to、see to、depend on等由动词和介词构成的短语动词后接that宾语从句时,先加it作形式宾语,再接that从句。 Please be so kind as to see to it that all the alterations are made at once!
