說明文是SAT文章閱讀考試中最重要的一種類型，經常在真題中看見有文章和題目出現。說明文是相對比較簡單的文章類型，也是大家能夠取得高分的重要保證，下面大家就和小編一起來看看這類的SAT閱讀文章蓋如何分析吧。

　　說明文是“介紹或是報道一個客觀的事物”。對比說明文是現實生活中常見到的一種閱讀。我們可以用讀新聞報道的方式去閱讀和分析說明文。

　　passage

　　the intelligence of dolphins is well documented by science. studies show that dolphins are able to understand sign language, solve puzzles, and use objects in their environment as tools. scientists also believe that dolphins possess a sophisticated language: numerous instances have been recorded in which dolphins transmitted information from one individual to another. a recent experiment proved that dolphins can even recognize themselves in a mirror something achieved by very few animals. this behavior demonstrates that dolphins are aware of their own individuality, indicating a level of intelligence that may be very near our own.

　　解析：

　　我們說，說明文是介紹一個事物。也可能是一個新事物，就像這篇關于海豚智商的報道。它說：“海豚的智商用科學的方法很好地記錄下來了。”這是一個topic sentence,如同是一個文章的議論文的主題或是記敘文背景，規范了文章或是短論的內容和邏輯范疇。

　　在這里，通過第一句我們知道這里所要涉及的是海豚的智商，而且，也明確地告知，所講述的內容是科學方法記錄海豚智商。這里的重點是科學方法。什么是科學方法是讀者關心的問題。

　　首先，什么是“科學”?在廣義上說科學是一個過程或是一種方法，如：“科學”=“critical 思維”+“實驗”+“觀察”。當然，組成科學的這三部分的先后順序倒是無所謂。正如下面這個文章結構：

　　topic sentence:

　　the intelligence of dolphins is well documented by science.

　　first 觀察揭示：

　　studies show that dolphins are able to understand sign language, solve puzzles, and use objects in their environment as tools.

　　second 科學家相信：

　　scientists also believe that dolphins possess a sophisticated language: numerous instances have been recorded in which dolphins transmitted information from one individual to another.

　　third 實驗證明：

　　a recent experiment proved that dolphins can even recognize themselves in a mirror something achieved by very few animals. this behavior demonstrates that dolphins are aware of their own individuality.

　　結果是海豚的智商和我們人類差不多：

　　those facts indicated a level of intelligence of dolphins that may be very near our own.

　　首先，我們發現，如果你對“科學”一詞理解正確，那么，studies show, scientist believe, and experiment prove 這三句的出現就是理所當然 anticipated answers。

　　進一步，如同在上面所做加工，再完善一下，我們完全可以把一個段落改寫成一個文章。而且結構幾乎是完全對稱。這便是英文寫作強調的一種幾何美。

　　通過上面的分析我們就可以看到SAT文章閱讀考試中說明文的閱讀是可以按照一定的規律進行的，所以天道專家建議考生在備考SAT閱讀考試的時候，根據文章類型的不同練習不同的閱讀方法，這樣就更加有針對性，也能更加容易取得好成績了。
