英 语 精 练 册 1 第四部分 语篇题组综合练 题组四 2 Ⅰ. 阅读理解C A Strange Siphon（虹吸管） A siphon is a simple tool for moving water from one place to another, and it's usually made with a tube or hose（软管） of some kind. 3 Here's one that's made of nothing but paper: 1.Tear off five squares of toilet paper and gently roll them into a long cylinder（圆柱形）. 4 2.Fill one of the glasses with water, stand it next to the empty glass and lay the paper into the glasses as shown in the picture. 3.Leave the glasses in this arrangement, and check them a day later. 5 What happened? Some of the water—as much as half of the water if your siphon works well—will have moved from the full glass to the empty glass. 6 Water is made up of tiny particles（颗粒）， and a piece of paper contains tiny spaces between the paper fibers（纤维） that hold onto water particles. Those tiny spaces pull water along with a force called “capillary action（毛细作用）”. In your siphon, they pulled the water particles over into the empty glass. 7 【主旨大意】本文是一篇应用文。主要介绍了虹吸管的制作及工作原理。 8 1.细节排序题 Which is the right order of the experiment? a. Fill one of the glasses with water, and stand it next to the empty glass. b. Check the glasses a day later. c. Roll five square of toilet paper into a long cylinder. d. Lay the paper into the glasses. e. Leave the glasses with water and a siphon still.( ) C A. a-b-c-d-e B. b-a-c-e-d C. c-a-d-e-b D. d-a-c-b-e 9 【解析】 细节排序题。根据实验内容可知正确的顺序是：把几张纸卷成一个长圆筒→把其中一个杯子装满水，放在空杯子旁边→把纸放进玻璃杯里→把杯子里的水和虹吸管留在那里→一天后再检查杯子。 10 2.What happened to the water in the full glass at last （if the siphon works well）?( ) B A. All of the water moved to the empty glass. B. As much as half of the water moved. C. A little water moved. D. Nothing changed. 11 【解析】 细节理解题。根据“Some of the water—as much as half of the water if your siphon works well—will have moved from the full glass to the empty glass.”可知如果虹吸管工作正常的话，多达一半的水会从满杯里转移到空杯里。 12 3.Why does the siphon work in this experiment?( ) B A
