套句展示：

It is universally acknowledged that + 句子(全世界都知道…)

这是一个在四级作文里面用来阐述观点的经典句型，用词也很出色。

It is universally acknowledged that trees are indispensable to us. 全世界都知道树木对我们是不可或缺的。

It is…that + 句子…构成强调句型(The Emphatic Pattern)

英语常用的强调结构是“It is/was+被强调部分(主语、宾语或状语)+ who(that)…”。一般说来，被强调部分指人时，用who;指事物时，用that;在美国英语中指事物时常用which来代替that。

与之类似的常用句型还有：

It is conceivable that + 句子(可想而知的)

It is obvious that + 句子(明显的)

It is apparent that + 句子(显然的)

It is conceivable that knowledge plays an important role in our life. 可想而知，知识在我们的一生中扮演一个重要的角色。

必考套句：

(1) It is the responsibility of to do sth.

【分析】注意，从形式上看该句子很像强调句型，而实际上并非如此，因为句中it是形式主语，动词不定式作实际主语。

It is the responsibility of every citizen in our society to do his utmost to protect the environment.

(2) It is the , I suppose, that havehas given rise to .

【分析】该强调句型强调句子主语，I suppose作为插入语。这是一个很好掌握的四级长句，在作文中需要分析原因时，可以用它阐述自己的看法。

It is the tighter job market, I suppose, that has given rise to the increase in the number of unemployed college students in China.

(3) It is only when that .

【分析】强调句型强调when引导时间从句。

It is only when you nearly lose someone that you become fully conscious of how much you value him.

伟人伟招：

1. 百折不挠式

We must accept finite disappointment, but we must never lose infinite hope. (Martin Luther King, Jr.)

我们必须接受失望，因为它是有限的，但千万不可失去希望，因为它是无穷的。(马丁·路德·金)

【点评】该句为马丁·路德·金生命的体验，我们在作文中谈到某种麻烦的解决方法时，借用过来妙不可言。另外We must do…, but we must never…用于观点的转折或者递进效果很好。

2. 深入生活式

Genius is formed in quiet, character in the stream of life. (Goethe )

天才形成于平静中，性格来自于生活的激流。(歌德)

【点评】歌德之才，恐非我辈能及，但大师的语言却给我们无穷的灵感。表示“形成”记着用“is formed in”，简单之处见真章。
