实验目的：观察水的沸腾实验方法：,1.,在烧杯中放入适量的水；,2.,把温度计放入水中；,3.,点燃酒精灯，仔细观察温度计和水的变化实验结果：,1.,在水温,60,以下时，随着水温不断升高，杯底气泡,(bubble),越来越多，有少量气泡上升；,2.,水温在,60,90,之间时，杯底气泡逐渐减少，气泡上升逐渐加快；,3.,达到,100,时，气泡上升越来越快温度不再变化实验结论：水在,100,时开始沸腾参考词汇：烧杯,beaker,；温度计,thermometer,；酒精灯,(alcohol burner),注意：,1.,词数,100,词左右；,2.,可适当增加细节，以使行文连贯第一步：布局谋篇很关键,审题,1.,确定体裁：本文为一篇,_,；,2.,确定中心人称：本文主要人称为,_,；,3.,确定主体时态：以,_,为主构思,第一部分：介绍实验的,_,和所需,_,；,第二部分：叙述实验的,_,；,第三部分：得出实验的结论实验报告,第一人称,一般现在时,目的,实验器材,方法及结果,第二步：核心词汇想周全,1._,观察温度,2._,做实验,3._,给水加热,4._,观察温度计度数,5._,得出结论,6._,开始沸腾,observe the temperature,carry out the experiment,heat the water,observe the number of the thermometer,draw a conclusion,start boiling,第三步：由词扩句雏形现,1.This experiment _ the temperature when water boils and what happens in water during boiling.,该实验的目的是观察水沸腾时的温度及发生的变化。
2._,，,I prepared the following equipment,：,a test tube,，,water,，,thermometer,，,beaker and alcohol burner.,为了做实验，我准备了以下器材：试管、水、温度计、烧杯和酒精灯is designed to observe,To carry out the experiment,3.Now you can see that _,，,plenty of bubbles form on the water surface.,现在你能够看到，当温度达到,100,时，大量的气泡会在水面形成4.After the experiment,，,I can draw a conclusion,：,water starts boiling at 100 degrees centigrade _.,实验后，我得出结论：水在,100,时会沸腾，另外大量的气泡会在沸腾时出现when the temperature reaches 100 degrees centigrade,with plenty of bubbles appearing during boiling,第四步：句式升级造亮点,1.,用,that,引导的主语从句、,with,复合结构改写句,3,Now _ plenty of bubbles form on the water surface _.,2.,用,that,引导的同位语从句、,while,引导的时间状语从句改写句,4,After the experiment,，,I can draw a conclusion _ at 100 degrees centigrade _ during the boiling.,it can be seen that,with the temperature reaching 100 degrees centigrade,that water starts boiling,while plenty of bubbles appear,第五步：过渡衔接连成篇,This experiment is designed to observe the temperature when water boils and what happens in water during boiling.To carry out the experiment,，,I prepared the following equipment,：,a test tube,，,water,，,thermometer,，,beaker and alcohol burner.,Procedure,：,First,，,half-fill the test tube with water.Then put the thermometer in it.Finally,，,heat the water,，,and observe the number of thermometer.Now you can see that when the temperature reaches 100 degrees centigrade,，,plenty of bubbles form on the water surface.,After the experiment,，,I can draw a conclusion,：,water starts boiling at 100 degrees centigrade with plenty of bubbles appearing during boiling.,。
