[对应学生用书第56页] Writing——如何写实验报告 实验报告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。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。 实验报告通常包括以下内容： 1.实验目的：表明为什么要做这个实验。 2.实验用品：交代做实验要用的物品。 3.实验方法和过程：清楚、具体地写明实验步骤。在组织文字时，要正确运用表示顺序的词。 4.实验结果：如实且正确地记录实验现象或数据。 5.结论：通过实验得出相关的结论。 [基本框架] 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)。 [常用词语] 1.aim　　　　　　　　　 目的；目标 2.material 材料 3.stage 阶段 4.do/carry out/conduct an experiment 做实验 5.do research on 就……进行研究 6.with the purpose of 带着……的目的 7.the aim of the experiment 实验的目的 8.find out 找出；查明 9.learn from the experiment 从实验中得知 10.draw/reach/arrive at/come to a conclusion 得出结论 [常用语句] 1.Below is a description of a simple scientific experiment. 下面是一个简单的科学实验的描述。 2.Leave the test tube alone for one week. 让试管静置一周。 3.Boil the water for three minutes. 把水煮三分钟。 4.Now, you can see that if I make a flame, there's gas coming out and blowing the flame. 现在，你能看到：如果我给它点火，就会有气体喷出，同时吹动火焰。 5.After the experiment, I can draw a conclusion：water starts boiling at 100 degrees centigrade with plenty of bubbles appearing during boiling. 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。 请根据下列表格中的内容，写一篇80词左右的英语短文，说明整个实验的内容。 实验目的 镁在空气中燃烧时是否有变化 实验用品 镁(magnesium)、本生灯(a Bunsen burner)、天平(a balance)、坩埚(a crucible) 实验步骤 1.首先把镁放进坩埚内； 2.然后把坩埚放在天平上称一下； 3.下一步点燃本生灯，把坩埚放在上面，给镁加热； 4.最后称镁的重量。 实验结果 镁比原来重了一点 实验结论 镁在空气中燃烧，重量上有变化 __________________________________________________________________________ __________________________________________________________________________ __________________________________________________________________________ __________________________________________________________________________ __________________________________________________________________________ [审题谋篇] 明确体裁话题：实验报告，镁在空气中燃烧 确定人称时态：以第三人称及一般现在时为主 布局文章架构：首段：呈现实验目的 中段：具体步骤 尾段：实验结论 列出核心要点： 1.实验要达到的目的； 2.操作步骤； 3.实验结论。 [词汇推敲] 1.________ 发现 2._______________ 在空气中燃烧 3._____________________________________________ 做实验 4.__________________ 重量发生变化 [遣词造句] ①The aim of the experiment is to find out _____________________ when magnesium burns in the air. 实验的目的是弄清楚镁在空气中燃烧时是否有变化。 ②All these things are ready, and ____________________________. 一切准备就绪后，你就可以开始做实验了。 ③You can find that it weighs _________________________. 你会发现它比以前重了一点。 ④_________________ in weight when magnesium burns in the air. 镁在空气中燃烧时，重量会发生变化。 [句式升级] 1.用“with复合结构”升级句② ______________________________________________________________________ 2.用“find复合结构”升级句③ ______________________________________________________________________ 3.用“that's because…”升级句④ ______________________________________________________________________ [妙笔成篇] ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ [参考范文] The aim of the experiment is to find out if there's a change when magnesium burns in the air. To carry out the experiment, you need the following things：magnesium, a Bunsen burner, a balance and a crucible.With all these things ready, you can begin the experiment. First, put the magnesium in the crucible.Then put the crucible on the balance and weigh it.Next, heat the magnesium.Light the Bunsen burner and hold the crucible over it.Finally, weigh the magnesium again. You can find it weighing a little more than before.That's because there is a change in weight when magnesium burns in the air. 假如你是李华，请根据以下提示写一篇实验报告。 实验目的：观察水的沸腾。 实验步骤： 1.在烧杯中放入适量的水； 2.把温度计放到水中； 3.点燃酒精灯，仔细观察温度计和水的变化。 实验结果： 1.水温在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.水温达到100℃时，气泡上升最快，水面气泡最多，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.写作词数应为80左右； 2.可适当增加细节，以使行文连贯。 ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ [参考范文] 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：water, a thermometer, a beaker and an alcohol burner. Procedure： First, half-fill the beaker with water.Then put the thermometer in it.Finally, light the alcohol burner and heat the water, and observe the readings of the thermometer.Now it can be seen that plenty of bubbles rise from the bottom of the water surface with the temperature reaching 100 degrees centigrade. After the experiment, I can draw a conclusion that water starts boiling at 100 degrees centigrade while plenty of bubbles rise to the surface during the boiling. $$
