學霸說明文寫的好，原來都在偷偷學這些技巧！
★說明文是對事情的發生、發展、結果、特徵、性質、狀態、功能等進行解釋、介紹、闡述的一種文體。說明文的種類很多，主要有事物說明文和事理說明文。說明文有三個特點：知識的科學性；行文的條理性；語言的準確性。
高考中說明文的命題形式一般為圖表、圖畫或文字提示。
英語說明文一般採用三段式：第一段主要引出說明的對象及說明的目的；第二段說明事物的主要特徵或做事情的方法或步驟；第三段進行總結概括。
寫作時要注意：
(1)仔細審題，明確說明對象，抓住要說明的事物或事理的主要特徵。
(2)選擇合理的說明順序。思路要清晰，層次要分明。要根據不同的說明對象，採用不同的說明順序，如時間順序、空間順序或邏輯順序等。
(3)根據不同的說明對象，選擇恰當的說明方法，比如定義法、舉例法、比較法和細節描述法等，不要遺漏主要內容。
(4)語言要準確。說明文寫作時態通常用一般現在時。寫作時要使用準確、明晰的語言來說明事物的特徵，避免對讀者造成誤導。
(5)根據說明順序及內容選用恰當的過渡詞和句型結構。表達應客觀、簡潔、明了，一般不加個人觀點。
