Section Ⅳ Writing an experiment report
Step 1|品教材范文
The experiment is designed to prove whether air pressure really exists.
At the beginning of the experiment, I prepared the materials, including a boiled egg, a glass bottle whose neck is a bit smaller than the egg and some hot water.With all the things prepared, the experiment began.
First, I removed the shell of the egg.Then, I carefully poured some hot water into the bottle, and shook the bottle gently.After a few minutes, I poured out the hot water.Just at the same time, I quickly placed the egg on top of the bottle.To my amazement, the egg squeezed into the bottle at once.
After the experiment, I can draw the conclusion that air pressure indeed exists, and it is very powerful.It is the force of the air that pushed the egg into the bottle.
Step 2|析写作手法
学语言
首段中使用动词短语be designed to,表明了实验目的。
第二段中使用介词including,列举了实验所准备的材料。使用with复合结构,对做实验前的准备工作做了总结。
第三段中使用first, then, after a few minutes, just at the same time,使实验步骤一目了然。
尾段中使用强调句,突出实验所得出的结论。
学结构
本文使用了“总—分—总”结构,开头部分介绍实验的目的;主体部分描述实验中使用的材料并解释实验步骤;结尾部分为结论,报告实验结果以及你所学到的东西。
