it常见句型汇总 it作形式主语和形式宾语是英语中非常核心的语法手段，既能避免头重脚轻，又能让表达更地道、更灵活。 一、It 作形式主语 当主语是动词不定式、动名词或从句时，为避免头重脚轻，常用it作形式主语，将真正的主语后置。 1. It + be + 形容词 + (for sb.) to do 说明做某事的性质、难易、重要性等。常用形容词有important, necessary, hard, easy, safe, common等。 It is necessary for teenagers to get enough sleep. 青少年保证充足的睡眠是很有必要的。 It’s hard for me to express my feelings in a foreign language. 用一门外语表达自己的感受对我来说很困难。 2. It + be + 形容词 + (of sb.) to do 当形容词描述的是人的品质或特征时，用of sb.。此类词有kind, brave, wise, foolish, polite, generous, silly等。 It was generous of you to share your notes with me. 你把笔记与我分享，真是太慷慨了。（= You were generous to share your notes with me.） It would be silly of us to give up now. 我们现在放弃的话就太傻了。 3. It + be + 名词/形容词 + doing 用于表示“好处、用处、乐趣、浪费”等意义，真正主语是动名词。 It is no use crying over what cannot be changed. 为无法改变的事哭泣是没有用的。 It’s a waste of time arguing with people who never listen. 和从来不听别人说话的人争论，简直是浪费时间。 It is worthwhile spending some time outdoors every day. 每天花点时间在户外活动是值得的。 4.

It + be + 形容词 + that ... (should) do 当形容词表示重要性、必要性或带有意外语气时（如important, necessary, strange, natural, a pity 等），that从句常用“should + 动词原形”，should有时可省略。 It is essential that every student (should) follow the lab rules. 每位学生都必须遵守实验室规定，这很关键。 It is strange that he should react so coldly to the good news. 真奇怪，他居然对好消息反应如此冷淡。 6. It + be + 名词 + that 从句 名词有a wonder, a shame, a pity等。若含“竟然”之意，从句也可用should。 It is a pity that she should miss such a valuable opportunity. 真遗憾，她竟然错过了这么宝贵的机会。 It’s a wonder that the old house survived the earthquake. 那座老房子在地震中完好无损，真是个奇迹。 It’s a shame that you can’t stay longer. 你不能多待一会儿，真是可惜。 7. It + be + 过去分词 + that 从句 常用said, reported, believed, announced, hoped, expected等。 It is believed that music can help reduce stress. 人们相信音乐有助于减轻压力。 It was announced that the flight would be delayed by two hours. 据宣布，航班将延误两小时。 若过去分词表示建议、命令、要求（如suggested, ordered, required, recommended），that从句用“should + 动词原形”，should可省略。 It is recommended that all passengers (should) arrive two hours early. 建议所有乘客提前两小时到达。 It was demanded that the report be finished before Friday. 要求这份报告在星期五之前完成。 8. It + 不及物动词 + that 从句 常见动词有seem, appear, happen, occur, strike, dawn on, matter等。 It seems that we’ve taken the wrong bus. 看来我们坐错公交车了。 It suddenly struck me that I hadn’t locked the front door. 我突然想起自己没锁前门。 It never occurred to her that the message might have been misunderstood. 她从没想到那条信息可能被误解了。 It goes without saying that health comes first. 不言而喻，健康是第一位的。 It dawned on me that I had made a terrible mistake. 我恍然大悟，自己犯了一个可怕的错误。 9. 常见固定句式 （1）It is (high/about) time that... （该是……的时候了） 从句多用一般过去时，或用should do（should不省略）。 → It is about time you started taking your studies seriously. 你该认真对待学业了。 （2）It is/was the first/second ... time that ... （这是第几次做某事） 主句为is时，从句用现在完成时；主句为was时，从句用过去完成时。 → It was the second time she had visited that museum. 那是她第二次参观那座博物馆。 （3）It is/has been + 时间段 + since ... （自从……以来已有多久） since从句用一般过去时。 → It has been three years since I last saw him. 我上次见到他已经是三年前了。 （4）It will be + 时间段 + before... （要过……才……） → It will probably be another week before we receive a reply. 大概还要过一周我们才能收到回复。 → It wasn’t long before the fire was brought under control. 不久火势就得到了控制。 （5）It takes (sb.) + 时间 + to do （做某事花费某人多长时间） → It took them two months to renovate the house. 翻新那栋房子花了他们两个月的时间。 （6）It is up to sb. to do （由某人决定做某事） → It’s up to the manager to make the final call. 由经理来做最终决定。 （7）(It is) no wonder (that) ... （难怪……） → No wonder the baby is crying; he must be hungry again. 难怪宝宝在哭，他肯定是又饿了。 二、It 作形式宾语 当宾语是动词不定式、动名词或从句，且后接宾语补足语或用于某些固定搭配时，常用it作形式宾语，将真正宾语后置。 1. 动词 + it + 宾语补足语 + 不定式/动名词/that从句 常用动词有find, think, consider, believe, feel, make等。 I find it challenging to stay focused when there’s so much noise. 周围这么吵，我发现很难保持专注。 We consider it impolite to keep others waiting. 我们认为让别人一直等着是不礼貌的。 She made it a habit to review what she had learned each day. 她养成了每天复习所学内容的习惯。 I think it important that everyone (should) be informed in advance. 我认为提前通知每个人很重要。 2. 动词 + it + 介词结构/从句 某些带介词的动词短语，以及表示喜好、感谢、依赖等结构，也常借助形式宾语it。 （1）appreciate / like / hate / enjoy / love + it + if/when 从句 → I really appreciate it if you could offer me some advice. 如果你能给我一些建议，我会非常感激。 → She loves it when the whole family gets together for dinner. 她特别喜欢全家人聚在一起吃晚饭的时刻/情景。 → I hate it when people cry. 我厌烦别人哭。 → I like it when you do that. 我喜欢你那样做。 （2）take it for granted that ...（把……视为理所当然） → He takes it for granted that his assistant will handle all the arrangements. 他理所当然地认为助手会处理好所有安排。 → We took it for granted that we’d be invited to the party. 我们想当然地认为会被邀请参加晚会。 （3）see to it that ... （确保……） → Please see to it that the windows are closed before the storm. 请务必在暴风雨来临前把窗户关好。 → Can you see to it that the email goes out this afternoon? 你能确保今天下午把电邮发出去吗？ （4）depend/rely on it that ... （相信/指望……） → You can rely on it that the work will be finished on time. 你放心，这项工作一定会按时完成。 三、强调句型：It is/was ... that ... 这是it的另一种重要用法，用来强调句子中除谓语之外的成分（主语、宾语、状语等）。结构为：It is/was + 被强调部分 + that/who + 剩余部分。 It was in that very bookstore that I came across this rare edition. 正是在那家书店，我偶然发现了这个珍贵的版本。 It was not until midnight that he finally finished the report. 直到半夜，他才终于完成了报告。 It is teamwork that makes the project successful. 正是团队合作让这个项目取得了成功。 1 学科网（北京）股份有限公司 $
