Answer 1

【答案】

【1】D

【2】B

【3】A

【解析】

本篇是科普知識(shí)，介紹冰在何種常態(tài)下溶解更快，由實(shí)驗(yàn)可知熱量傳遞到冰塊的速度越快，冰塊融化的速度就越快。

【1】推理判斷題。根據(jù)題圖內(nèi)容可知本篇是冰在何種常態(tài)下溶解更快的實(shí)驗(yàn)步驟，是物理實(shí)驗(yàn)；故選D。

【2】推理判斷題。根據(jù)題圖The faster the heat transfers to the ice cube，the faster the ice melts …Heat transfers faster from warm water to the ice than it does from warm air and objects in the room to the ice… The foil makes it harder for heat to reach the ice.熱量傳遞到冰塊的速度越快，冰塊融化的速度就越快；從溫水到冰的熱量傳遞比從溫暖的空氣和房間里的物體到冰的熱量傳遞要快，鋁箔使熱量更難到達(dá)冰。可知未包裹的冰塊在溫水中接受的熱量最快，融化得最快，故選B。

【3】推理判斷題。根據(jù)題圖“Try This …Write down your best guess and then try this experiment”可知文章的目的是為了鼓勵(lì)讀者做實(shí)驗(yàn)；故選A。

本篇都考查推理判斷能力。解答前要先快速閱讀全文，理解大意；再閱讀題干，正確理解題干的要求；然后回歸原文，尋找有用信息作答；題1根據(jù)常識(shí)，判斷冰在何種常態(tài)下溶解更快的實(shí)驗(yàn)是屬于物理實(shí)驗(yàn)；題2要根據(jù)題圖的內(nèi)容——熱量傳遞到冰塊的速度越快，冰塊融化的速度就越快，據(jù)此來(lái)排除表述錯(cuò)誤的選項(xiàng)，題3根據(jù)題圖的敘述推斷本文寫(xiě)作意圖。
