初中英語中考：閱讀理解之說明文

考點(diǎn)四十七閱讀理解之說明文

k5考點(diǎn)詳解/

"英語說明文”，顧名思義，就是一種以“說明、解釋“為主要表總方式的英語文體。它是對客觀事

物的性狀、特點(diǎn)、功能和用途等作科學(xué)解說的。它既不像故事那樣重在情節(jié)的敘述和描寫，也不像議論文

那樣，重在闡明主張和論點(diǎn)論據(jù)；更不像科幻作品那樣富于想象和虛構(gòu)夸張。說明文是通過解說事物、闡

明事理，使人們增長知識(shí)和技能。說明文是高考英語閱讀理解題中的重點(diǎn)內(nèi)容之一。說明文具有與自己特

點(diǎn)相適應(yīng)的說明方法，因此說明文結(jié)構(gòu)復(fù)雜，專業(yè)術(shù)語多，易于拉開考生分?jǐn)?shù)檔次，便于高校分層次選拔

人才。然而對于考生來說說明文抽象度高，解題難度大。高考對說明文的考查多為科普知識(shí)，動(dòng)植物特性、

自然現(xiàn)象和新產(chǎn)品、新工藝介紹以及人文地理、風(fēng)土人情等方面的說明文，文中解釋性、定義性、說明性

的句子居多。因此考生要掌握說明文的命題特點(diǎn)，敘述方式，以冷靜的心態(tài)閱讀原文，重點(diǎn)突破長句結(jié)構(gòu)

特點(diǎn)和邏輯關(guān)系，以便對其做出準(zhǔn)確的語意理解。

說明文閱讀理解的特征

一般說來，英語說明文與其他文體一樣，文章所涉及的內(nèi)容不外乎以下幾個(gè)方面，即who-what-

when—>where—>how—>why。

1.who：問的是這篇文章的主體是誰？（即所要說明和描述的人或事物）

2.what：問的是主體做了什么事情？（即主體表現(xiàn)出的特性、功能和用途）

3.when和where：是在何時(shí)何地發(fā)生的？（即何時(shí)何地所表現(xiàn)出的特性、功能和用途）

4.how：通過什么方式表現(xiàn)出來的？

5.why：這種特性功能用途的原因是什么？

做說明文閱讀理解題的時(shí)候，一定要記住上面的wh-word。邊閱讀，邊搜記，牢記要點(diǎn)，把握全文。
