考前赢分第27天核心知识it的用法it有许多不同的用法，主要有下面几种情况，最常用的是：一、指前面提到的东西：1. he bought a book and gave it to me.（代表前面的中性名词，这类情况最多）2. he has a baby, he loves it（or him or her）.（it可以代表baby）he has got a pig，he has kept it five months.（it可代表动物）3. he tried to get up, but found it impossible.（指句子前面某部分表示的意思）he learns music, and it will take him many years.i must say something, but it is impossible.4. he arrived yesterday, but nobody knows it.（代表前面整个句子，但在这种情况下用that更好一些。）john hates children, and it is strange. that she knows him and they have been schoolmates, it is a fact.二、指句子后部的东西，此时的it通常是形式主语或形式宾语。用作形式主语：其中，不定式和从句作真正主语的这类句式很常见，动名词作真正主语的少一些，主要是以no good, no use, useless, senseless, worthwhile, dangerous, nuisance, waste等词作表语的句子中。 its no use talking to him. he wont listen. （代表动名词）it is wonderful, swimming in summer.（代表动名词）（较少见）2. 用作形式宾语（置于含宾语补足语的动词后面），能用这种结构作宾语的动词常见的有：think, find, consider, judge, feel, make, take等： i suppose it wrong to tell lies.（代表后面的不定式短语）he thinks it foolish to learn music.（代表后面的不定式短语）i think it impossible that he should ill-treat her.（代表后面的名词从句）i suppose it mysterious how he got rich.（代表后面的名词从句）3一些表示喜恶等动词的后面不能直接带从句，虽然此时没有宾语补足语，但习惯上仍然要用it充当填补词。如：like, dislike, hate, appreciate, see to等。he would be much appreciated if you could do him that favor. 如果你能帮他这个忙，他将十分感激。三it也可用来四、it用于强调句型it is/wasthat结构：用来对句子的某部分加以强调。当被强调部分表示人时，还可以用who做连词，即：it is/was who。 it is he that/who has brought me up with a true love.it is me that he has brought up with a true love.（对主语进行强调用主格，对宾语进行强调用宾格）it is with a true love that he has brought me up.经典例题1.there is still a copy of the book in the library. will you go and borrow _?no, id rather buy _in the bookstore. a. it; oneb. one; onec. one; it d. it; it2. _ worries me the way he keeps changing his mind.
