It及其它代词的常用句型

It及其它代词的常用句型在高中阶段的英语学习中，物主代词It虽然看似简单易学，但是如果忽视对它的学习，不注意归纳总结，势必会影响整体能力的提高。现将It的常用句型归纳如下：1.It 表时间、距离、天气等(情景用法)：It 表示时间、距离、天气等时，可以与start 和get (变得)连用，来表示天气的变化。Start 后面多用形容原级，而get 后面多用形容词的比较级。如：It will get cooler.(天气会变冷。)It will start humid and cold.(天气开始变得潮湿寒冷.)It 作为代词，有时可以指代自然环境，有时可以指代一个彼此都知其所指的东西。Where does it hurt? （哪儿疼啊？)How far is it from here?(那个地方离这儿有多远？)It is about 3 hours ride.(开车大约需要三小时。)It will be ok/all right/fine.（没问题。）2. Who is it? （谁啊？）（情景用法）：在英语中，it在如下集中情况中可以指代人：当听到有人敲门时，就要问Who is it?(谁啊？)另外it 还可用来指代婴儿，以及走在黑暗出的身影等，如：The baby opened its eyes.接听电话时，会问对方：Who s that?回答则是:This is John Smith speaking.这里要注意区分that, his以及it在不同场合下的不同使用。基本句型：Eg. Who is it?(After hearing the knock at the door.)(谁啊？)Its me, John Smith.(是我，约翰 史密斯)Eg. Look at the baby! It is so cute.(快看这个婴儿，真可爱啊!)进阶句型：Eg. I hate it when people talk with their mouth full.Eg. We all take it for granted that heavy objects fall faster than light ones.3.It is +形容词+动名词/不定式在这个It is +形容词+动名词/不定式句型中，it 是形式主语，真正的主语是后面的动名词或不定式，这要看习惯用法，多数情况下用不定式还是用动名词在意思上没有太大的区别，如果在形容词后直接跟不定式，就表示“对于（人）来说”如：It is easy for me to understand it.(对我来讲理解这个很容易。)Eg.It isnt easy being a teenager.Eg.It is difficult being parent.Eg.Its a very popular play and it would be wiser to book seats in advance.(in advance 的意思是“提前，事先”;book/reserve 表示“预定座位、机票等。)4.It is +形容词比较级+不定式情景用法：这个句型表示“做什么更什么些“，这里的it 是形式主语。如果要表示更为强烈的对比，还可以在比较级前加上表示程度的词，如much 等。但要注意，如果形容词的原形是个多音节词，如beautiful, difficult, interesting, 等，此句型就会写成It is much more beautiful /difficult/interesting to 此外，此外，如果此句式做了I think 的宾语，is还可以省略。其结构为I think it more difficult to find a good job now.(我认为现在要找到一份好的工作难多了。)Eg. Maybe it would be better to stay here and relax for a while.Eg. It is easier to do shopping now.Eg. It is more difficult to make real friends now.5.It is +名词+不定式情景用法：这里的名词多为抽象名词，常见的此类名词有：fun,pity,pleasure,honor等。如表示对对方的宴请，或邀请某人到某地发言，就可以说It is my great honor to talk to all of you.(能够和你们交谈我真是太荣幸了。)基本句型：Eg.It is fun to talk with him.(和他交谈很快乐。)Eg.It is my great honor to know all of you here.(和这里的各位结识真是我莫大的荣幸。)Eg.It is a pleasure to have been working with you for all these days.(这些天和各位在一起工作真的使我很开心。)进阶句型：Eg.My father thought it a pity to leave home so early every day.(Eg.I find it a must to learn English well.(此处是名词的用法)（我认为学好英语势在必行。）6.It is ones turn to do sth.(轮到某人做某事。)Take turns to do sth.Take turns at doing sth.（轮流做某事。）有时还可使用in turns 或by turns 来做副词。基本句型：Eg.Whose turn it to speak?(该轮到谁讲话了？)Eg.It is my turn to tell a story today.Eg.I think it should be his turn to do the cleaning.进阶句型：Eg.
