四、作形式主语，替代主语从句，动词不定式，或动名词短语：

⑵It is important ( necessary， right， strange， natural) that 从句 常译为┅是重要的(必要的,对的,奇怪的,自然的┅)that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去，建议记住该句型中的形容词。

⑺It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/ ) that从句

that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。

2作形式主语替代不定式　

⑴ It is kind ( of sb ) to do sth 不定式的逻辑主语是由 of引起，主句中的形容词必须是能表示逻辑主语特征的褒义或贬义形容词。 常见的词有：

bad ， brave ， careless， clever ， cruel ， foolish ， good （好心的）， honest ， horrible ， kind ， lazy ， modest ， naughty ， nice（有教养的）， polite， rude ， silly ， stupid ， wise ， wrong（错误的）等。 这个句型可以改写为：sb is kind to do sth 。　 如:It is kind of you to say so = You are kind to say so

⑵It is necessary ( for sb ) to do sth 不定式的逻辑主语是由for引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的中性形容词。 常见的形容词有：

important， necessary， natural easy ， safe ， common ， normal ， hard ， difficult ， dangerous ， unusual， rare ， impossible ， pleasant

CF: keep sth, in mind / keep in mind that

六、it的重要句型

1强调句型: It is/was + 被强调部分 + that 从句 (被强调的主语如果是人，that可以由who换用)

①It was about 600 years ago that the first clock with a face and an hour hand was made

②It was they that (who ) cleaned the classroom yesterday

特例:It is not until + 被强调部分 + that 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是 not until 的强调形式。

It was not until she took off her dark glasses that I realized she was a famous film star

B

试题分析：考查it的特殊用法。本题的it北称为模糊it，在句中没有意思，但是不能省略。如I

hate

it

when

it

is

hot。我讨厌天气太热。本句的it和例句的it是同一个用法。句意：如果你能给我一些建议，我将非常感激。故B正确。

点评：在英语中it可以指时间，地点，度量衡等，也可以做形式主语，形式宾语，或者引导强调句型。也可以指代前面提及的同一个人或者事情。要特别模糊it的用法。

以下是我为大家整理的it 的用法 总结 ，希望能帮助大家更好地认识it这个单词，提高英语水平。

1 It is + 被强调部分 + that

该句型是强调句型。将被强调的部分放在前面， 其它 部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，that可以由who换用。如果把这种句型结构划掉后，应该是一个完整无缺的 句子 。这也是判断强调句型与其它从句的 方法 。

It was about 600 years ago that the first clock with a face and an hour hand was made

It was they that (who ) cleaned the classroom yesterday

It was in the street that I met her father

2 It is clear ( obvious, true, possible, certain) that

该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为"清楚(显然，真的，肯定)"　是主语从句最常见的一种结构。

It is very clear that he’s round and tall like a tree

= That he’s round and tall like a tree is very clear

3 It is important ( necessary, right, strange, natural) that

该句型和上一个同属一个句型。由于主句中的形容词不同，that 后的从句中要用虚拟语气(should + 动词原形)，should 可以省去。建议记住该句型中的形容词。

It is important that we (should) learn English well

It is necessary that he (should) remember these words

4 It is not until + 被强调部分 + that

该句型也是强调句型。主要用于强凋时间状语，译成汉语"直到才"，可以说是 not until 的强调形式。

It was not until she took off her dark glasses that I realized she was a famous film star

= Not until she took off her dark glasses did I realize she was a famous film star

= I didn’t realize she was a famous film star until she took off her dark glasses

5 It is said (reported, learned) that

该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为"据说(据报道，据悉)"。

It is said that he has come to Beijing

It is reported that another earth satellite has been put into orbit

6 It is suggested ( ordered ) that

该句型和上一个同属一个句型。主句中的过去分词是表示请求，建议，命令等词时，that　后的从句要用虚拟语气(should + 动词原形)，should 可以省。常译为"据建议;有命令)

It is suggested that the meeting ( should ) be put off

It was ordered that we ( should ) arrive there in two hours

7 It is a pity ( a shame ) that

该句型中，that后的从句一般用虚拟语气(should + 动词原形)，should可省去表示出乎意料，常译为"竟然"。没有这种意义时，则不用虚拟语气。

It is a pity that such a thing ( should ) happen in your class

这种事竟然发生在你们班上，真是遗憾!

It is a pity that he is ill 他生病了，真遗憾!

8 It is time ( about time ,high time ) that

该句型中that 后的从句应该用虚拟语气，值得注意的是① 常用过去时态表示虚拟② 有时也用should + 动词原形，should 不能省。常译为"是(正是)的时侯"。

It is time that children should go to bed

= It is time that children went to bed

9 It is the first ( second ) time that

该句型要和上一个句型区别开来。该句型中的 that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态;如果是一般过去时，后面从句则用过去完成时态。该结构中 that 可以省去;it有时用 this 替换常译为"是第一(二)次"。

It is the first time I have been here

= This is the first time I have been here

10 It is since

该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。

It is ( has been ) 5 years since his father died

11 It is when

该句型中的 when 引导的是一个时间状语从句，主句中的 it 指时间，表语由具体的时间充当。常译为"当的时候，是"。

It was 5 o’clock when he came here

12 It be before

该句型主句中的 it 指时间, 主句中的时态常是将来一般时或过去时两种时态主句中的表语多是long, not long , 3 days , 2 weeks 等表示时间段的词或 短语 。常译为"之后"。

It was 3 days before he went to Beijing

It will be not long before he finishes his job

13 It happens (seems, looks, appears ) that

该句型中it是形式主语，that 引导的是主语从句，主句中的happen , seem等词是不及物动词

It happened ( so happened ) that he met his teacher in the street 碰巧

It seems that he will be back in a few days 看来

14 It takes sb to do sth

该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。常译为"做要花费某人"。

It took thousands of people many years to build the Great Wall

15 It is no good (use ) doing sth

该句型中的真正主语是动名词短语，主句中的表语可以是no good , ( not any good ) , no use , ( not any use )。

It is no good learning English without speaking English

16 It doesn’t matter whether ( if )

该句型中whether(if) 引导的从句是真正主语，该句型常译为　"不论(是否)没关系。

It doesn’t matter if they are old

17 It is kind ( of sb ) to do sth

该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由 of引起，主句中的形容词必须是能表示逻辑主语特征的形容词。常见的有： bad , brave , careless, clever , cruel , foolish , good (好心的), honest , horrible , kind , lazy , modest , naughty , nice(有教养的), polite, rude , silly , stupid , wise , wrong(错误的)等。 这个句型可以改写为：sb is kind to do sth

It is kind of you to say so

= You are kind to say so

18 It is necessary ( for sb ) to do sth

该句型与上一个同属一个句型。如果不定式的逻辑主语是由for引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有：① important, necessary, natural ② easy , safe , common , normal , hard , difficult , dangerous , unusual, rare , impossible , pleasant等。

在①中的形容词作表语可以用从句改写， 如：

It is important for her to come to the party

= It is important that she (should ) come to the party

19 It looks ( seems ) as if

该句型中it无意义。 as if 引导一个状语从句。常译为，"看起来好象"如果与事实不相符合，则用虚拟语气

It looks as if he is ill(真的病了)

It looks as if he were ill (没有生病)

It seemed as if he were dying

20 We think it important to learn a foreign language

该句型中的it 作形式宾语。为了记忆方便我们可称该句型为"6123结构"。

6指主句中常用的动词：think, believe, make, find, consider, feel;

1指的是形式宾语it;

2指的是宾补的两种形式：形容词或名词;

3指的是真正宾语的三种形式：不定式短语，动名词短语或that引导的宾语从句。

We think it our duty to clean our classroom every day

He felt it important learning English well

They found it difficult that they would finish their work in two days
