It is dangerous ______ children to swim in the river alone. It is polite ______ you to say “thank you” to others. It is necessary ______ doctors to work day and night. for for for of of 【拓展句型一】 “It is/was+形容词+that ...”意为“……是……的”。主要用于表达说话人对that从句所描述内容的“观点、态度、判断或感受”，也是这类句式与其他形式主语用法的核心区别。在该句型中，it是形式主语，句中的形容词是核心修饰成分，that从句是句子真正的主语。当主句用is时，从句根据实际情况用一般现在时、一般将来时等；当主句用was时，从句常用表示过去的某种时态。 ◆ It’s wonderful that our hometown has changed a lot. 我们的家乡变化很大，真是太好了。 ◆ It was strange that he didn’t come to school today. 他今天没有来上学，真奇怪。 It is/was+形容词+that ...的用法 【拓展句型二】 It + is / was + n. (短语) + that 从句 2. 该结构用于表达“......是一件......的事”。that从句作为真正的主语对前面的名词(短语)进行解释说明。 常见名词短语有 a pity, a fact, a shame, good news,no wonder等。 It is a pity that you missed the concert.很遗憾你错过了那场音乐会。 It is no wonder that he is so tired-heworked all night. 难怪他这么累，他工作了一整晚。 该结构用于表达“据说/据报道/据认为......”，be动词后接过去分词，整体多用于被动语态.这类结构常用来转述信息，无需明确动作的执行者（即“谁据说、谁报道”），使表达更客观、更简洁。常见的过去分词有said, reported, believed, known, suggested 。 It is said that he has won first prize.据说他获得了一等奖。 It was reported that the accident happened atmidnight. 据报道，事故发生在午夜。 【拓展句型三】 It + is / was + done + that 从句 It 句型用 法小结 It 句型 It + is/was + adj. + to do sth. 做某事是怎么样的 It + is/was + adj. + for sb. + to do sth. It + is/was + adj. + of sb. + to do sth. It + is/was + ... + that 从句 ......是......的 对某人来说，做某事是怎么样的 It + is / was + n.
