Ｉｔ　ｂｅ句型大放送

張宏杰

縱觀近三年的高考試題，我發(fā)現(xiàn)對“It be”句型的考查頗多，但考生們答得都不是很理想，所以特地把“It be ”句型總結(jié)如下：

一、It is/was +被強(qiáng)調(diào)部分+that/who+其它，該句型是強(qiáng)調(diào)句型。

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

It was not until she took offher dark glasses that I realized she was a famous film star.

二、It +be +adj./n./-ed+真主語

該句型中It作形式主語，主要包括：

1.It is +adj.+for/of sb.+to do sth(It 代替不定式作形式主語)

例如：It is very important for me to study English well.

It is very kind of you to help me.

2.It is +n./adj.+doing sth.(it 代替動(dòng)名詞作形式主語)

例如：It is no use helping him.

It is no good taking this medicine.

It is dangerous playing with fire.

3.It is +adj./n./-ed+that從句（It代替從句作形式主語）

(1) It is dear/obvious/possible/certain/true+that從句

例如：It is very clear that he is round and tall like a tree.

It is obvious that his words areright.

(2) It is important/necessary/vital/essential/desirable/imperative+that從句（該從句中可用虛擬語氣should+do,也可不用should而只用動(dòng)詞原形）

例如：It is important that we (should) learn English well.

It is necessary that he (should) remember these words.

大家要注意的是，并非所有形容用于這一句型，that從句都要用虛擬語氣，上面所列舉的形容詞以及其他具有類似含義的形容詞用于這一句型時(shí)，that 從句才用虛擬語氣。若是別的意義的形容詞用于這一句型， that從句用陳述語氣。

例如： It is strange that they finished the task quickly.

(3) It is a pity /a fact / a shame +that 從句

例如：It is a fact that English is being accepted as an international language.

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

(4) It is said/reported/learned/thought/believed+that 從句

例如：It is said that the book has been translated into foreign languages.

It is reported that another earth satelllite has been put into orbit.

(5) It is suggested/ordered+that從句（從句中用虛擬語氣should+do）例如：It is suggested that the meeting (should) be put off.

It is ordered that we (should) arrive there in two hours time.

三、It be +時(shí)間+從句（該句型中it指時(shí)間）

1. It is /was+時(shí)間點(diǎn)+when從句

例如：It was 5 oclock when he got home.

2. It be +時(shí)間段+before從句

例如：It will be many years before we meet again.

It was 3 days before he went to America.

3.It be +時(shí)間段+since從句

例如：It is/has been 3 years since we met last time.

It was 3 years since he had left that school.

四、It is (high) time that 從句 （從句用虛擬語氣should do 或過去時(shí)態(tài)）

例如：It is time that childern should go to bed.

It is time that children went to bed.

五、It be the first /second……time that 從句（從句用完成時(shí)態(tài)） 例如：

It is the first time that Ive been here.

It was the first time that I had been here.

六、It be the +形容詞最高級+that (從句用完成時(shí)態(tài)) 例如：

It is the best flim that Ive ever seen.

It was the worst film that I had ever seen.

七、It is(not)(just) like sb to do sth.某人恰恰(不)是……這個(gè)樣子例如：
