A.GeographyB.BiologyC.ChemistryD.Physics

【2】Which of the following is most probably the result of this experiment?

A.The ice cube on the plate melted most slowly.

B.The unwrapped ice cube in warm water melted fastest.

C.The ice cube in your hand melted more slowly than the one on the plate.

D.The ice cube wrapped in foil melted faster than the unwrapped one in warm water.

【3】The purpose of the passage is to ________.

A.encourage the readers to do the experiment

B.advise the readers to do things on their own

C.teach the readers to melt ice cubes in different ways

D.ask the readers to guess the result of the experiment

Answer 1

【答案】

【1】D

【2】B

【3】A

【解析】

本篇是科普知识，介绍冰在何种常态下溶解更快，由实验可知热量传递到冰块的速度越快，冰块融化的速度就越快。

【1】推理判断题。根据题图内容可知本篇是冰在何种常态下溶解更快的实验步骤，是物理实验；故选D。

【2】推理判断题。根据题图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.热量传递到冰块的速度越快，冰块融化的速度就越快；从温水到冰的热量传递比从温暖的空气和房间里的物体到冰的热量传递要快，铝箔使热量更难到达冰。可知未包裹的冰块在温水中接受的热量最快，融化得最快，故选B。

【3】推理判断题。根据题图“Try This …Write down your best guess and then try this experiment”可知文章的目的是为了鼓励读者做实验；故选A。

本篇都考查推理判断能力。解答前要先快速阅读全文，理解大意；再阅读题干，正确理解题干的要求；然后回归原文，寻找有用信息作答；题1根据常识，判断冰在何种常态下溶解更快的实验是属于物理实验；题2要根据题图的内容——热量传递到冰块的速度越快，冰块融化的速度就越快，据此来排除表述错误的选项，题3根据题图的叙述推断本文写作意图。
