一、英語四級說明文的選項特徵
1. 選項簡潔概括、不完整句子居多，最多有一至二題細節體
2. 選項往往比較抽象，一般以 it / they / man / woman /等抽象名詞做主語
3. 選項往往表達因果、目的、手段的小詞 如：because / by / to
4. 選項具備科學性、客觀性的特點，但選項之間缺乏邏輯關系
二、英語四級說明文的文章特點
1. 文章緊緊圍繞一個事物或事件進行描述，深入淺出，要求知其所以然
2. 文章緊扣一個中心事物，著重描寫一個熟悉事物的與眾不同處
3. 語言平實、簡潔、明白，有時會用以下修辭方法：分類法、舉例子、做比較、列數字
4. 層次結構清楚，多為總分結構
5. 開篇引題，重點不分明。但以設問開頭的說明文除外。
三、英語四級標志詞常出現的位置
1. 在每個層次的啟承處
判斷個層次的啟承主要有兩種方法一種是聽序數項標志詞如：on the other hand / another / second等等;第二種是聽“氣”即語速，語音，
語調有所變化的地方。
2. 段落開頭、結尾處，前三後二
應該重視的原則
聽即原則、主題原則、層次原則、原因原則、轉折原則、求異原則：注意事物的與眾不同處、替換原則：數字，年代等一般需要重新定位。
科技類說明文：重點注意三個“age”即advantage 優勢、disadvantage 劣勢、usage 用途。
環境類說明文：重點在於產生環境問題的原因及解決方法。
實驗類說明文：重點在於實驗目的、實驗手段、實驗結果。
演講類說明文：重點在於演講主題、說話人的觀點、文章走向。

B. 大學英語四級閱讀理解是什麼類型的文章說明文
1．社會來問題方面。如包括家庭、婚自姻、倫理、犯罪、青少年問題、婦女問題、種族問題、交通、住房、環境、能源等等。
2．人文科學方面。涉及到政治、經濟、法律、歷史、地理、文化、習俗、教育、娛樂、人物等等。
要積累各個方面的單詞，推薦使用滬江開心詞場，裡面類別詞書比較豐富。
C. 2001年以來英語四級閱讀理解中，記敘文考了多少次，說明文考了幾回。謝謝
閱讀理解部分比例調整35%，大學英語四級考試的閱讀文章體裁有記敘文、說版明文、議論文，其中說明文和議權論文為主要測試文體；在閱讀題材方面，科技類大約佔25%，人文類大約佔45%，經濟類大約佔15%，綜合類大約佔5%，環境類比例小，近幾年有上升趨勢。
D. 英語四級中的議論文和說明文怎麼區分
很簡單，議論文，就是叫你討論一個問題嘛！有論點和論據。說明文就是讓你敘述一件事物！
E. 求好的英語四級作文模版，議論文和說明文個一篇，四級每次都差一點過，求求各位大神，小弟感激不盡
