分析 文章大意:這篇短文主要介紹了現(xiàn)在比過(guò)去有更多的火災(zāi),主要原因是干燥,炎熱及大風(fēng).同時(shí)人們還發(fā)現(xiàn)嚴(yán)格的滅火使森林植被更厚,更容易起火.現(xiàn)在科學(xué)家認(rèn)識(shí)到只要大火對(duì)人類構(gòu)不成嚴(yán)重的威脅,不是所有的火都要被熄滅.
解答 79-81:DCA
79.D 細(xì)節(jié)與邏輯推理.根據(jù)原文第二段"In 2010,Russia had the hottest and driest summer in a century."(2010年,俄羅斯經(jīng)歷了一個(gè)世紀(jì)最炎熱干燥的夏天),同時(shí)根據(jù)文段總起句子"The first reason is climate(氣候)change",可知是與氣候有關(guān).選項(xiàng)D的內(nèi)容與氣候相關(guān),因此推測(cè)出本題答案為D.
80.C 主旨?xì)w納.根據(jù)第四段的中心句"Scientists now understand that a fire can be a natural part of a healthy forest"(科學(xué)家們知道火可以是森林健康的自然的一部分)這句話,知道整段都是講的適當(dāng)?shù)幕馂?zāi)對(duì)森林有益的一面,再結(jié)合選項(xiàng),排除掉其他無(wú)關(guān)的選項(xiàng),就可推斷出答案選C.
81.A 判斷題.選項(xiàng)A說(shuō)并不是所有的火都必須被撲滅,我們從第四段可知這一說(shuō)法是正確的;B說(shuō)人們的疏忽導(dǎo)致了危險(xiǎn)的火災(zāi),這個(gè)文章沒(méi)有涉及,故不選;C說(shuō)澳大拉亞允許所有的火自然燃燒,顯然過(guò)于絕對(duì),錯(cuò)在"all"一詞;D說(shuō)俄羅斯比美國(guó)有更多火災(zāi),文章沒(méi)有進(jìn)行比較,沒(méi)有涉及這一內(nèi)容.綜合以上分析,選擇A是正確的答案
點(diǎn)評(píng) 本文是一篇日常生活類閱讀,題目涉及多道細(xì)節(jié)理解題,做題時(shí)結(jié)合原文和題目有針對(duì) 性找出相關(guān)語(yǔ)句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案.
