七、it的用法

　　2.作句子的形式主語，代替不定式、動(dòng)名詞或從句。

　　It took me five minutes to finish reading the exercise.

　　It cost me five yuan to buy the pen.

　　The color TV set costs me more than 2，000 yuan.

　　I spent ten hours in finishing the work.

　　I spent twenty yuan on the shirt.

　　It is no use crying now. You'd better study hard now.（it is no use doing sth. ）

　　To his surprise， it turned out that Tom failed the entrance examination.（to one's surprise 使某人感到驚奇）

　　It's a pity that you didn't watch the match.

　　It is necessary for us to have some exercise every day.

　　3.作句子的形式賓語，代替不定式、動(dòng)名詞或從句。

　　They all regard it their duty to help the poor people.

　　I don't think it worthwhile taking so much trouble.（It's worthwhile doing. 做……事是值得的）

　　We find it difficult to learn English without practicing.

　　I don't think it very important that we should take part in the discussion.（take part in 參加）

　　4.構(gòu)成強(qiáng)調(diào)句型。當(dāng)強(qiáng)調(diào)的部分是主語，并且主語是人時(shí)，句型中的that 也可以換作who.

　　強(qiáng)調(diào)句基本構(gòu)成 it is that…

　　It is in the room that we met each other for the first time.

　　It was not until 1936 that basketball became a part of the Olympic Games.（not until 直到……才）

　　It was they who attended the meeting last week.

　　It is because the book is so useful for my work that I bought it.

　　考試重點(diǎn)

　　that和those有時(shí)分別用來代表前面提到的不可數(shù)名詞和名詞復(fù)數(shù)，以避免重復(fù)。而可數(shù)名詞單數(shù)往往用the one 或that one 來代替。that 可以指上面提到的事情，this指下面要談的事情。

　　不定代詞中，both 放在實(shí)意動(dòng)詞前，系動(dòng)詞be 的后面。every只能跟名詞，each可以跟名詞也可以不跟名詞。every在代詞部分要出現(xiàn)當(dāng)每隔……講。

　　few， a few， many 修飾或指代可數(shù)名詞，little， a little， much修飾或指代不可數(shù)名詞。few， little表示否定。

　　one the other，some others，the others

　　it用法重點(diǎn)就是強(qiáng)調(diào)句。it作為形式賓語時(shí)不接is.

　　代詞部分的難點(diǎn)之一是名詞型物主代詞與形容詞型物主代詞的區(qū)別。顧名思義，形容詞型物主代詞起的是形容詞的作用，在句子中只能作定語，名詞型物主代詞起的是名詞的作用，代替上文出現(xiàn)的名詞，在句子中一般作主語、賓語、表語等。

　　Let's clean their room first and ______ later.

　　A. our      B. us        C. we          D. ours

　　（答案為D，ours 相當(dāng)于our room.）

　　代詞部分的主要考核點(diǎn)是不定代詞。如some， any， few， a few， little， a little， many， much， one， none， all， both， either， neither， each， every， other， another， 以及some， any， no， every 與body， one， thing 構(gòu)成的合成代詞。

　　（1）泛指與特指。如：another， other， others 是泛指，the other， the others是特指。

　　（2）肯定與否定。如：a few， a little， either， some 及其合成代詞表示肯定，few， little， none， neither， any 及其合成代詞表示否定。

　　（3）可數(shù)與不可數(shù)。如：few， a few， many， one 修飾或指代可數(shù)名詞，little， a little， much修飾或指代不可數(shù)名詞。

　　代詞部分的另一個(gè)考核點(diǎn)是it.

　　it 可以代替上文出現(xiàn)的單數(shù)事物。

　　The picture was changed while drawn from memory as it passed through the class. （it 指代the picture.）

　　it takes sb. some time to do sth. 花費(fèi)某人多長時(shí)間做某事

　　It takes half an hour or so to walk to the bus stop.

　　He made it plain that he was annoyed with me.

　　it 還可以構(gòu)成強(qiáng)調(diào)句型，即“It is / was +被強(qiáng)調(diào)的部分+ that …”。當(dāng)強(qiáng)調(diào)的部分是人，并且是主語時(shí)，that可以換成who.強(qiáng)調(diào)句去掉it is / was 與that即成為普通的句子。

　　It was last night that I saw you in the restaurant.

　　It was she who / that suggested that he go to New York in order to get a direct flight.
