語言的功能在于表達，而表達的方式是多種多樣的。當一個詞影響到？?以溝通。英語當中多功能解釋性語句，就可以起到這一作用。請看下面的句子：

　　He is a dumb. = He is a person who can not speak。

　　He refused. = He said “no”。

　　I’ve never seen such a stubborn person. = I’ve never seen such a person who never listens to other’s advice。

　　解釋性語句能幫助我們巧妙地避開一些大詞，難詞，又能使意思表達流暢，不失為一聰明之舉。比較下面兩篇文章：

　　(1) Examination is a common headache to students all over the world. They all detest is, but all being domineered by it. It represents a trial; the grade its verdict。

　　Nowadays, examination has become a popular form of testing. It almost can dominate one’s future. I am not exaggerating; for you all know it is true. If we want to obtain a diploma, we must first pass the exams. If we do not have a diploma, we may not find a job easily. That is the reason why all students are nervous and pale when they are sitting for an important examination which may concern their future。

　　But as long as examination is on its peak of power, we must be philosophical of it. Do not always think of the harm that it brings, but think of the good it may do to us. If we do not have exams, we may indulge ourselves in other things instead of books. Exams have to always drive us on. What is wrong for learning more and thoroughly?

　　(2) Examination is a common headache to students all over the world. They all dislike it (hate it)， but all being ruled by it. It is a trial; the grade its decision。

　　Nowadays, examination has become a popular form of testing. It almost can control one’s future. I am telling the truth, for you all know it is true. If we want to get a graduation paper, we may not find a job easily. That is the reason why all students are nervous and pale when they are sitting for an important examination which may have something to do with their future。

　　But as long as examination is on its highest point of power, we must have a calm attitude to it. Do not always think of the harm that it brings, but think of the good it may do to us. If we do not have exams, we may spend our time on other things instead of books. Exams have to always drive us on. What is wrong for learning more and deeply?

　　比較兩篇文章，第一篇短小精干，用詞準確，不失為一篇優秀作文。而第二篇全篇采用最普通的詞匯，意思同樣清楚，也不失得體，流暢。

　　四、六級作文的評分標準一般側重于能清楚地表達意義，段落，層次有系統性，語法正確，而并不過分強調用詞的精確度。因此作文應試的要領應該是快捷、清楚、流暢。

　　所以，就考試而言，碰到難詞或遺忘詞時，過分地把時間花在“鉆牛角尖”上是不明智的，而應該采取靈活的思維方法、迂回的戰術，運用簡單、易記的詞匯及表達方式，從而能夠運用有限的詞匯寫出美妙的文章，輕松自如地駕馭語言，把握時機，以聰明克服缺陷，以機智靈巧克服學究式的笨拙，以少勝多，最大限度地發揮自己的潛能。

　　最后預祝大家都能取得好成績！
