It seems amazing that at my age I am still fit enough to cycle 20 kilometres in an afternoon.本句是复合句，it为形式主语，真正的主语是后面的that从句。此外，也可以是不定式短语、动名词短语或主语从句。It is +adj. +that从句，真正的主语是that从句，常见的it作主语的复合结构还有：（1） it is a fact (a shame/ a pity/ no wonder) that（2） It is said (reported/ decided/ suggested) that（3） It seems (happened/ doesnt matter/ has turned out) thatIt is hard to finish the work in two days.2. When I was taken off the school football team because I was unfit, I knew it was time to quit smoking. It was time to do sth. 表示“到的时候了”It is (high) time for sb to do sth=It is (high/about) time that sb. did/should do sth. 到某人做某事的时候了It is high time for us to say good-bye.=It is high time that we should say goodbye.3. Every time you feel like smoking a cigarette, remind yourself that you are a non-smoker.该句是一个主从复合句，从句为every time引起的一个时间状语从句，词句中every time起到了连词的作用。英语中起连词作用的名词词组还有：each time(每次)；next time(下一次)；the first/ last time(第一次/ 最后一次)；the moment/ instant/ minute(一就)等。Each time I was in trouble, he could e to help me out. 3、 重点语法总结Grammar: the use of “it”（I）（一）it用作人称代词和非人称代词 1. 作人称代词人称代词it一词是有实际意义的，是单数第三人称代词。主格与宾格相同。（1） 指代人以外的一切生物或事物，如前文提到的事物或未指明但谈话双方都知道的那件事。Qingdao is a beautiful city, isnt it?It doesnt matter. （2）替代前文中的this，thatThis is your plan? Will you hand it in? （3）指代婴儿，小孩或性别不明的人The baby is crying. It might be hungry.-Someone is ringing. Who might it be?-It must be my friend Tom. He (不可用it) wants to see you.2. 作非人称代词it用作无人称的主语，不指物，而表示时间、天气、环境、气候、季节、距离、金钱等自然现象，或指事物的状态。It was very noisy at that time.(指代环境)It is half past three now.(指代时间)It is six miles to the nearest hospital from here.(指代距离)It was very cold.(指代天气)It is 5 dollars.(指代金钱)3. it, one, that, those和which的区别：1) it 指上文提到过的同一样事物，one则泛指上文提到过的同一类事物中的一个；There are many dictionaries in that bookstore. So I bought one.(one泛指其中之一)2) that 作代词替代前面提到的事物(多用于比较)，可数名词，不可数名词皆可，代替可数名词可用the one代替，that的复数形式为those,只可替代可数名词的复数，在句中相当于the ones.The head teacher in your class is younger and more active than that in theirs.The students who do best in the exam are not always those with the best brains.3) it和which都可用来指代某一事件，关键要看两个句子之间是否有并列连词，如果有就用it，反之用which。He was badly ill, and it made his mother worried.He was badly ill, which made his mother worried.(which指代前面整个主句，在定语从句中作主语)（二）it作形式主语It is difficult to translate the article.(真正的主语是动词不定式短语，it为形式主语)It is no use going there so early.(真正的主语是现在分词短语，it为形式主语)It is obvious that he is a cheater.(真正的主语是that从句，it为形式主语)it可充当形式主语，本身无意义，后面真正的主语通常是不定式结构，-ing分词结构，或名词性从句。（三）it用作形式宾语I found it possible to do this regularly.(it 为形式宾语，真正的宾语是to do this regularly)She thought it no use worrying about him.(it为形式宾语，worrying about him是真正的宾语)He made it clear that his family is poor.(it为形式宾语，真正的宾语是that从句)it作形式宾语常见的结构有：主+谓语+it+adj/n+动词不定式/动词-ing形式/从句（四）it用于强调句型中It was him who/that you should ask.(被强调部分是人时，既可用who,也可用that)It was on the street that I found the bag.(被强调部分是地点，只能用that)it用于强调句型当中，强调句型的基本结构为：it is/was+被强调部分+that/who+句子其他成分。（五）it的其他固定搭配1.
