语法填空-无提示词（代词”it”）课件-2025届高三下学期英语一轮复习专项

代词 “it” 1. 【形式主语】 当不定式、动名词、从句等复杂成分用作句子主语时，为保持句子平衡，通常把真正的主语放在句末，而在句首使用形式主语it。 ①　 it 作形式主语替代不定式构成“It + be + adj. for (of) sb to do sth”某人做某事……                                                 . 他很难下定决心。                                                 . 你能帮助我你人真是太好了。 【说明】介词 of 与 for 的区别是： of 用于指某人的性格、属性、特征等；for表示对象，意为“对……来说” It's hard for him to make up his mind. It's very kind of you to help me. 　It is V-ed + that ...据...... 1) It is said (reported, learned) + that…                                                 . 据说习主席来过英德。 2) It is suggested ( ordered, demanded, insisted, commanded) + that …    从句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气(should + V原形).should可以省略。译为“据建议；有命令…”                                                . 据建议会议应该延期。 It is said that President Xi came to Yingde. It is suggested that the meeting should be put off. ③　It is a pity (a shame) that… 表示出乎意料，that后的从句一般用虚拟语气(should+V原形), should 可以省略。 译为“竟然”。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing (should) happen in your class. 真遗憾，这样的事情竟然发生在你们班。 It is a pity that you miss the opportunity. 很遗憾你错过了这个机会。 ④　 It is necessary(important, essential,natural,strange) that… that 后的从句一般用虚拟语气 (should+V原形), should 可以省略.
