2018年英語四級寫作指導(dǎo)之強調(diào)句

　　一、強調(diào)句精彩套句展示

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

　　是一個在四級作文里面用來闡述觀點的經(jīng)典句型，用詞也很出色。

　　It is universally acknowledged that trees are indispensable to us. 全世界都知道樹木對我們是不可或缺的。

　　It is…that + 句子…構(gòu)成強調(diào)句型(The Emphatic Pattern)

　　英語常用的強調(diào)結(jié)構(gòu)是“It is/was+被強調(diào)部分(主語、賓語或狀語)+ who(that)…”。一般說來，被強調(diào)部分指人時，用who;指事物時，用that;在美國英語中指事物時常用which來代替that。

　　與之類似的常用句型還有：

　　It is conceivable that + 句子(可想而知的)

　　It is obvious that + 句子(明顯的)

　　It is apparent that + 句子(顯然的)

　　It is conceivable that knowledge plays an important role in our life. 可想而知，知識在我們的一生中扮演一個重要的角色。

　　二、語法精講

　　1. 簡介

　　(1) 一般情況用It is (was)…that (who)…，指人時，用who;指物時，用that。

　　我們分別可以強調(diào)主語、賓語、表語、時間狀語和地點狀語等。如：

　　He read three books in the library yesterday.(正常句子)

　　It was he who read three books in the library yesterday.(強調(diào)主語)

　　It was three books that he read in the library yesterday.(強調(diào)賓語)

　　It was in the library that he read three books yesterday.(強調(diào)地點狀語)

　　(2) 強調(diào)狀語或定語時，只用that，不用when、where，如：

　　It is at 5 o’clock that the train will arrive.

　　(3) 被強調(diào)的部分是主語時，注意句子的謂語動詞和被強調(diào)的主語保持一致。如：

　　It is he who is late.

　　It is they who were late.

　　(4) 一般疑問句的強調(diào)句為“Is (was) it + that…?”;特殊疑問句為：“特殊疑問詞+ is (was) +it +that…?”結(jié)構(gòu)。如：

　　Was it ten years ago that his father died?(他的父親是十年前去世的嗎?)

　　When is it that you will set off?(你到底什么時候出發(fā)?)

　　(5)“not…until…”句型的強調(diào)結(jié)構(gòu)為“It is not until…that…”應(yīng)注意把否定詞not轉(zhuǎn)移到until前面。如：

　　I didn’t go home until the rain stopped.(直到雨停了我才回家)。

　　強調(diào)句為：It was not until the rain stopped that I went home.

　　I didn’t know the news until yesterday.(直到昨天我才知道那個消息)

　　強調(diào)句為：It was not until yesterday that I knew the news.

　　2. 四級必考套句學(xué)習(xí)

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

　　【分析】注意，從形式上看該句子很像強調(diào)句型，而實際上并非如此，因為句中it是形式主語，動詞不定式作實際主語。

　　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 have\has given rise to .

　　【分析】該強調(diào)句型強調(diào)句子主語，I suppose作為插入語。這是一個很好掌握的四級長句，在作文中需要分析原因時，可以用它闡述自己的看法。

　　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】強調(diào)句型強調(diào)when引導(dǎo)時間從句。

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