It seems amazing that at my age I am still fit enough to cycle 20 kilometres in an afternoon. 本句是復(fù)合句，it為形式主語，真正的主語是后面的that從句。此外，也可以是不定式短語、動名詞短語或主語從句。It is +adj. +that從句，真正的主語是that從句，常見的it作主語的復(fù)合結(jié)構(gòu)還有： （1） it is a fact (a shame/ a pity/ no wonder) that… （2） It is said (reported/ decided/ suggested…) that… （3） It seems (happened/ doesn’t matter/ has turned out…) that… It 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……的時候了” It is (high) time for sb to do sth=It is (high/about) time that sb. did/should do sth. 到某人做某事的時候了 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. 該句是一個主從復(fù)合句，從句為every time引起的一個時間狀語從句，詞句中every time起到了連詞的作用。英語中起連詞作用的名詞詞組還有：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、 重點語法總結(jié) Grammar: the use of “it”（I） （一）it用作人稱代詞和非人稱代詞 1. 作人稱代詞 人稱代詞it一詞是有實際意義的，是單數(shù)第三人稱代詞。主格與賓格相同。 （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談話雙方都知道的那件事。 Qingdao is a beautiful city, isn’t it? It doesn’t matter. （2）替代前文中的this，that This is your plan? Will you hand it in? （3）指代嬰兒，小孩或性別不明的人 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. 作非人稱代詞 it用作無人稱的主語，不指物，而表示時間、天氣、環(huán)境、氣候、季節(jié)、距離、金錢等自然現(xiàn)象，或指事物的狀態(tài)。 It was very noisy at that time.(指代環(huán)境) It is half past three now.(指代時間) It is six miles to the nearest hospital from here.(指代距離) It was very cold.(指代天氣) It is 5 dollars.(指代金錢) 3. it, one, that, those和which的區(qū)別： 1) it 指上文提到過的同一樣事物，one則泛指上文提到過的同一類事物中的一個； There are many dictionaries in that bookstore. So I bought one.(one泛指其中之一) 2) that 作代詞替代前面提到的事物(多用于比較)，可數(shù)名詞，不可數(shù)名詞皆可，代替可數(shù)名詞可用the one代替，that的復(fù)數(shù)形式為those,只可替代可數(shù)名詞的復(fù)數(shù)，在句中相當(dāng)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都可用來指代某一事件，關(guān)鍵要看兩個句子之間是否有并列連詞，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指代前面整個主句，在定語從句中作主語) （二）it作形式主語 It is difficult to translate the article.(真正的主語是動詞不定式短語，it為形式主語) It is no use going there so early.(真正的主語是現(xiàn)在分詞短語，it為形式主語) It is obvious that he is a cheater.(真正的主語是that從句，it為形式主語) it可充當(dāng)形式主語，本身無意義，后面真正的主語通常是不定式結(jié)構(gòu)，-ing分詞結(jié)構(gòu)，或名詞性從句。 （三）it用作形式賓語 I found it possible to do this regularly.(it 為形式賓語，真正的賓語是to do this regularly) She thought it no use worrying about him.(it為形式賓語，worrying about him是真正的賓語) He made it clear that his family is poor.(it為形式賓語，真正的賓語是that從句) it作形式賓語常見的結(jié)構(gòu)有： 主+謂語+it+adj/n+動詞不定式/動詞-ing形式/從句 （四）it用于強調(diào)句型中 It was him who/that you should ask.(被強調(diào)部分是人時，既可用who,也可用that) It was on the street that I found the bag.(被強調(diào)部分是地點，只能用that) it用于強調(diào)句型當(dāng)中，強調(diào)句型的基本結(jié)構(gòu)為：it is/was+被強調(diào)部分+that/who+句子其他成分。 （五）it的其他固定搭配 1. It is brave of her to go home alone at night. It is/was+adj (of/for sb) to do sth; 2. It is no use talking to him about it. It is/was no use/good+doing; it is well worth doing sth; 3. It was no wonder that she was so angry. It is/was no wonder（a pity/a shame）that…; 4. It is natural that he (should) say so. It is/was+adj+從句； 5. It is reported that the road was closed. It is/was+過去分詞+that從句（say,think,believe,hope,expect） 6. It (so) happens that the ticket were sold out. It (so) happened that…碰巧…… 7. It seems(seemed)/appears(appeared) that …似乎 8.
