　　文章客觀的語氣與它所采用的對比寫作方法都證明了它是說明文。文章客觀地對比了兩種學習方式的利弊，但是沒有主觀地把其中一個觀點強加給讀者，因為作者本人沒有表達觀點。兩個觀點的論據(jù)已經(jīng)畫線，由于內容比較散亂，我們要濃縮一下。我們首先分析一下學生的樣本，看看存在什么問題，如何改進。 學生樣本1 This article talks about whether to study alone or study in groups.Both studying alone and studying in groups are having advantages and disadvantages of their own. 學生樣本2 This paper discusses two ideas about how to study.On one hand，some students like studying alone，because they can use their time better.On the other hand，students like studying in groups because they can communicate with each other. 我們寫說明文概括的時候，主題句最好瞄準說明的對象來突出寫作目的，支撐句則說明對象有的特征補充被說明的對象。 兩個樣本的主題句都扣題，但不夠深入，文章是主要比較了兩種方法的好處。樣本1與樣本2的主題句差不多，但是它的支撐句太虛弱，沒有說明各自的優(yōu)點。因為“ … advantages and disadvantages of their own”過于簡單，沒有具體的內容。相反，樣本2各自列舉了“use their time better”和“ … communicate with each other”，雖然不夠準確，但是給了我們具體的內容，這是它的優(yōu)點。因此，樣本1可以評2分，樣本2可以評4分(5滿分)。 【答案】 主題句——瞄準說明的對象 The article compares the benefits of studying alone with those of studying in groups. 支撐句——說明對象的特征 Studying alone allows students to remain focuses and avoid interruption，while group study creates a more enjoyable learning environment.
