资源简介 / 让教学更有效 高效备考 | 英语学科Unit 2 Inspiring People单元语法精讲精练“It is/was ... (for/of sb.) to do ...” 和“It is/was+形容词+ that从句”用法句型一、It is/was ... (for/of sb.) to do ...的用法1. 句型结构分析:该句型中it是形式主语,无实际语义,指代后面的不定式短语,这样使用是为了避免主语过长导致句子头重脚轻。句子中真正主语是动词不定式“to do ...”。该句型中可以用for/of 来引出人物。该句型中be动词通常用单数形式。2. 句型的意义:如果不用for/of 引出sb.,句型的意义为“做某事......(省略的部分用形容词,对不定式动作进行评价)”。用for引出 sb.,这时句子侧重点是强调“事情”,重点不在人,这时形容词多是对“事情”进行评价的一些词,如:important, necessary, difficult, easy, hard, possible, impossible, dangerous等。例:It is important for us to keep healthy.对我们来说,保持健康很重要。(重点在“保持健康这件事。)It is difficult for him to finish the work today.对他而言,今天完成这项工作很难。It is dangerous for children to swim alone.孩子独自游泳很危险。果用for sb.(重点在于评价“孩子独自游泳”这件事)用of 引出sb.,这时句子侧重点是强调“人本身的品质/性格”,重点在评价人,这时形容词多是对“人”进行评价的一些词,如:kind, nice, good, polite, wise, clever, silly, stupid, careless, rude, wrong等。例:It is kind of you to help me.你真好,帮我忙。(重点在评价人的品质)It is stupid of him to believe such a lie.他真蠢,竟然相信这种谎话。(重点在评价人的品质)It was careless of her to leave the door unlocked.她太粗心了,居然没锁门。(重点在评价人的性格)3. 变否定句子变否定时,直接把not放 to 前。例:It is unnecessary for you to go there.你没必要去那儿。句型二、It is/was+形容词+ that从句的用法1. 句型结构分析:该句型中it是形式主语,无实际语义,指代后面的that从句,这样使用是为了避免主语过长导致句子头重脚轻。句子中真正主语是后面的that从句。该句型中be动词通常用单数形式。that是从属连词,只起“把从句绑进来”的作用,无实际意义。2. 句型的意义:该句型是对that从句表达的内容进行评价或说明,以为“...是...”例:It is clear that he is lying.很明显,他在撒谎。It is surprising that she got full marks.她拿了满分,真让人吃惊。It is important that we follow the rules. 我们遵守规则很重要。3. 变否定变否定直接在is/was后加not。例:It is not true that he stole the money.说他偷钱,这不是真的。It wasn’t surprising that they lost.他们输了,并不让人意外。4. 该句型中也可用for来引出句子描述的情况针对或适用的对象。例:It is important for us that the plan works.计划能成功,这对我们很重要。It is hard for him that he must leave. 他必须离开,这对他很艰难。【拓展句型】和以上两句型比较相似的句型有:1.

It + be + 名词 + that从句例: It is a pity that you can’t come to the party.你不能来参加聚会,真可惜。一、单项选择。1.It’s necessary ________ us ________ wash our hands before meals.A.of; to B.for; to C.of; for D.for; for【答案】B【详解】句意:饭前洗手对我们来说是必要的。根据固定句型 It’s+形容词+for sb. to do sth.“对某人来说做某事是……的”,此处形容词necessary“必要的/必需的”用来描述事情的性质,第一空用for;其后接动词需用不定式,第二空填to。2.It is important for teenagers ________ how to take care of themselves.A.learn B.learning C.to learn D.learned【答案】C【详解】句意:对于青少年来说,学习如何照顾自己是很重要的。固定句型“It is +adj.+for sb.+to do sth.”,意为“做某事对某人来说是……的”。it作形式主语,真正的主语是动词不定式短语,后面应接动词不定式 to do。3.________ is dangerous ________ people to get close to hungry wild beasts.A.That; for B.It; for C.This; of D.It; of【答案】B【详解】句意:人们靠近饥饿的野兽是危险的。It is +形容词+ for sb. to do sth.:适用于描述事物特征的形容词。It is +形容词+ of sb. to do sth.:适用于描述人物品质的形容词。此处的dangerous是形容词,描述事物特征,因此用介词for,主语用it。4.The doctors tell us that it is important ________ a healthy diet.A.of us to have B.of us having C.for us to have D.for us having【答案】C【详解】句意:医生告诉我们,对我们来说拥有健康的饮食是很重要的。of us to have对我们来说;of us having形式错误;for us to have对我们来说(多用于评价客观情况);for us having形式错误。固定句型“It is + adj. + for/of sb. to do sth.”。句中的形容词“important”(重要的)是描述后面所做事情的属性,而不是描述人的性格特征,故应用介词for引导行为的主体;再结合动词不定式符号to构成形式主语的真正主语部分,因此for us to have符合题意。5.It is important ________ us ________ learn to respect people with different abilities.A.for; to B.of; to C.for; / D.of; /【答案】A【详解】句意:对于我们来说,学会尊重不同能力的人是很重要的。句子是固定句型“It is+adj.+for/of sb.+to do sth.”,意为“对于某人来说做某事是……的”,当形容词是描述事物性质的词,如:important或difficult等,介词用for;当形容词是描述人物性格或品质的词,如:kind或helpful等,介词用of,因此第一空用for,排除选项B和D。it是形式主语,不定式是真正主语,第二空需填动词不定式符号to,排除选项C。6.—Was it wise ________ Li Ming ________ that decision —I don’t think so.A.of; making B.for; making C.of; to make【答案】C【详解】句意:——李明做那个决定是明智的吗?——我不这么认为。根据“It is+adj.+of+sb.+to do sth.”,形容词wise用来评价人的品质特征,介词应用of;该句型中真正的主语为动词不定式,第二空应填to make符合题意。7.It’s not far away from school. ________ only takes me ten minutes to walk there.A.This B.That C.I D.It【答案】D【详解】句意:离学校不远。我走到那儿只花费十分钟。根据固定句型“It takes sb. some time to do sth.”表示“做某事花费某人多少时间”,其中it作形式主语,真正的主语是后面的动词不定式to walk there。故选D。8._________ careless of you to make lots of mistakes.A.That’s B.It’s C.It D.Is【答案】B【详解】句意:你犯了很多错误真是太粗心了。固定结构“It’s+adj.+of sb.+to do sth.”表示“某人做某事是……的”,其中it作形式主语,真正的主语是动词不定式。9.— Was it necessary ________ Mike ________ some pictures before helping the old — I think so.
