master the tw cre sentence patterns: It is + adj. + (fr/f) sb. + t d sth. and It is + adj. + that..., and use them crrectly.​finish sentence transfrmatin and clze exercises skillfully t apply the grammar flexibly.​use the target patterns t describe inspiring peple and their deeds, cnnecting grammar learning with the theme "the pwer f rle mdels".
一、句型：It is/was + adj. (+ fr/f sb) + t d sth.1. “It is/was + adj. + t d sth.” 意为“做某事是……的”，是固定句式，其中 it 为形式主语，真正的主语是后面的动词不定式（短语）。因为真正的主语较长，而谓语部分相对较短，所以用 it 作形式主语，以避免“头重脚轻”。I think it’s imprtant t sleep eight hurs a day. 我认为每天睡8个小时很重要。
2. 在句型 “It is/was + adj. + fr/f sb + t d sth.” 中，sb 为动词不定式 t d sth 的逻辑主语。二者的具体用法为：It is/was + adj. + fr sb + tdsth.
意为“对某人来说，做某事是……的”；该句型中的形容词表示事物所具备的特征或客观情况。常见的形容词有 cheap, cnvenient, dangerus, difficult, easy, exciting, expensive, imprtant, interesting, necessary, pssible, useful, wnderful 等，fr 后的 sb 与后面的动词不定式（短语）之间存在逻辑上的主谓关系，即 sb 是 t d sth 的逻辑主语。
t is/was + adj.+f sb + t d sth.意为“某人做某事是……的”；该句型中的形容词描述的是人的特征、品质等。常见的形容词有 brave, careless, clever, flish, gd, helpful, hnest, kind, nice, plite, silly, stupid, wrng 等，f 后的 sb 与后面的动词不定式（短语）之间存在逻辑上的主谓关系，一般都可以转换成一个 f 后的宾语充当主语的句子
It’s necessary fr the students t d eye exercises twice a day. 对学生们来说一天做两次眼保健操是有必要的。It is kind f yu t share sme gd ideas with me. = Yu are kind t share sme gd ideas with me.你真好，和我分享一些好主意。
二 It 从句.“It 从句.”意为“……是……的”，是固定句式，其中 it 为形式主语，that 从句为真正的主语。当 that 后的从句较长时，为避免句子结构出现“头重脚轻”的情况，通常会使用 it 作形式主语，而将真正的主语（即 that 从句）后置。常见的结构主要有以下几种：
1. It is/was + 形容词 + that 从句.用于表达“……是……的”，常见的形容词有 imprtant, necessary, pssible, clear, strange 等，that 从句说明导致该形容词状态的原因或相关情况。
It is imprtant that we keep healthy.我们保持健康是很重要的。It is necessary that yu arrive n time.你准时到达是有必要的。
 注意当形容词表示“重要，必要，奇怪”等含义时，that 从句中的谓语动词常用“(shuld+)动词原形”，shuld 可省略。It is strange that she (shuld) knw me.很奇怪她竟然认识我。2. It is/was + 名词(短语)+ that 从句.
用于表达“……是一件……的事”。常见名词短语有 a pity, a fact, a shame, gd news, n wnder 等。that 从句作为真正的主语对前面的名词(短语)进行解释说明。It is a pity that yu missed the cncert.很遗憾你错过了那场音乐会。It is n wnder that he is s tired—he wrked all night.难怪他这么累，他工作了一整晚。
3. It is/was + 过去分词 + that 从句. 用于表达“据说/据报道/据认为……”，这类结构常用来转述信息。常见的过去分词有 said, reprted, believed, knwn, suggested 等。It is said that he has wn first prize.据说他获得了一等奖。It was reprted that the accident happened at midnight.据报道，事故发生在午夜。
