. 请根据下列内容，写一篇短文，说明整个实验的内容。 实验目的：不打烂鸡蛋取走蛋壳 实验器材：一个玻璃杯，一个小锅，水，一个鸡蛋，醋(vinegar)约250毫升 实验步骤：1.把鸡蛋放在锅中煮十五分钟左右； 2.把煮熟的鸡蛋放到玻璃杯中； 3.往玻璃杯中倒醋，醋要漫过鸡蛋； 4.让鸡蛋仔醋中浸泡24小时。 实验结果：24小时后，鸡蛋壳完全消失。 实验结论：醋中的酸性物质(acid)与蛋壳中的碳酸钙(calcium carbonate)反应生成二氧化碳(carbon dioxide)，蛋壳(shell)消失。 注意：词数：100—120。 写作指导：文章体裁是_______,因此时态可以是_______,全文可以这样分段： 内容及要点信息常用句型及词汇： 实验目的：the aim of the experiment is to…;in order to find out…;we carry out an experiment to…;with the purpose of…;in the hope of 实验器材：you need…;the following things are needed\will be used 实验步骤或方法：cook\boil,fill…in,weigh,wait,place,react反应,form；first,first of all,next,second,after that,finally, in the end,at last, for 15minutes,24hours later… 实验结论：from this we can conclude…we can learn from the experiment…we can find out that…the result is…you can see\discover… 连词成句，再用上恰当的过渡词连句成篇： 1. 这个实验的目的是取走蛋壳而不打烂鸡蛋。 The aim of the the experiment is to___ the shell from an egg___ ___the egg. 2.蛋壳消失是因为蛋壳中含有碳酸钙，而醋是酸性的，二者反应生成二氧化碳气体。 The egg shell disappears because it __________(由…组成) calcium carbonate ____(然而) the vinegar is an acid.The two substances ___ to ___the gas,___ ____. 参考范文： An Experiment The aim of the the experiment is to move the shell from an egg without breaking the egg. To carry out the experiment,you need the following things: a glass,a small pot\boiler,some water,an egg and about 250 ml vinegar.When all these things are ready,you can begin the experiment. First, boil the egg for about 15 minutes in a pot filled with water. Next, place the egg in the glass and cover it with vinegar.After that,leave the egg in vinegar for 24 hours. 24 hours later,you can see the shell disappear completely. The egg shell disappears because it is made up of calcium carbonate while the vinegar is an acid.The two substances react to form the gas, carbon dioxide. .. 本文来源：https://www.wddqw.com/doc/260da3e3c2c708a1284ac850ad02de80d4d806f1.html
