1、1Part Writing实验报告2所谓实验报告，就是把有关实验的目的、过程、结论等经过整理而形成的书面汇报材料。实验的内容主要包括：1.实验的目的和所用的仪器和辅助材料。2.实验步骤和方法。3.实验者的结论(如评价、体会、建议等)。因为实验报告是在科学实验的基础上得出的，因此，除从科学角度核对事实、检验数据外，还要力求语言准确、简明、扼要，任何臆想和猜测都是不能写入其中的。3【增分表达】1.描写实验目的(1)We carry out an experiment to find out.(2)the aim of the experiment is to.(3)with the purpose

3、arn from the experiment.(5)We can find out that.(6)Yon can see/discover.6假如你是李华，请根据下列内容提示，写一篇实验报告。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。7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6090 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

4、；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。8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9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 temperaturecarry out the experime

6、 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 observeTo carry out the experiment113.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10

7、0时会沸腾，另外大量的气泡会在沸腾时出现。when the temperature reaches 100 degrees centigradewith plenty of bubbles appearing during boiling12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3Now _ 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4After the experiment，I can draw a conclusion _ at 100 d

8、egrees centigrade _ during the boiling.it can be seen thatwith the temperature reaching 100 degrees centigradethat water starts boilingwhile plenty of bubbles appear13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

9、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.14本节内容结束
