Unit 3 Section Ⅳ Writing——实验报告-【正禾一本通】2024-2025学年高中英语必修第三册同步课堂高效讲义教师用书（外研版2019）

Section Ⅳ　Writing——实验报告 实验报告是把实验目的、过程、结果等记录下来，经过整理写成的书面汇总材料。实验报告要明确体现实验目的、步骤和结果，对具体实验现象的描述要客观准确，分析要全面具体，语言要简洁质朴、通俗易懂。 【写作指导】 Ⅰ.谨记写作范式 Ⅱ.积累话题素材 [常用词汇] ①do/carry out/conduct an experiment 做实验 ②experimental materials 实验材料 ③do research on...就……进行研究 ④with the purpose of...带着……的目的 ⑤the aim of the experiment is...实验目的是…… ⑥firstly..., secondly..., thirdly...首先……，然后……，接着…… ⑦find out 找出；查明 ⑧learn from the experiment 从实验中得知 ⑨draw/reach/arrive at/come to the conclusion 得出结论 ⑩in conclusion 总之 [出彩佳句] (1)描述实验目的、材料： ①The aim of the experiment is to find out the temperature and what happens when water is boiling. 实验的目的是观察水沸腾的温度和现象。 ②To do/carry out/conduct the experiment, you need the following materials：a beaker, a thermometer, alcohol lamp and a box of matches. 为了做实验，你需要下列材料：烧杯、温度计、酒精灯和一盒火柴。 (2)描述实验步骤： ①First，fill the beaker with about 100ml water. 第一，在烧杯里盛100ml左右的水。 ②Then, put a thermometer in the water. 然后，在水中放入温度计。 ③Next，heat the water in the beaker and watch the reading of thermometer. 接下来，加热杯中的水，并观察温度计的读数。 ④Finally, write down the temperature when bubbles begin to appear. 最后，气泡开始出现时记下温度。 (3)描述实验结果、结论： ①Some time later, bubbles begin to appear when the temperature reaches 100 Centigrade. 一段时间之后，温度达到100℃时开始出现气泡。 ②We can draw a conclusion that water boils when the temperature reaches 100℃. 我们可以得出结论：水在温度达到100℃时沸腾。 【实战演练】 假如你是李华，请根据下列表格中的内容写一篇实验报告，写作词数应为80左右。 实验目的 探究铝(aluminium)在空气中加热后重量是否会发生变化 实验器材 铝片，本生灯(Bunsen burner)，天平，坩埚(crucible)，坩埚钳(tongs) 实验步骤 1.把铝片放在坩埚里，然后放在天平上称重； 2．点燃本生灯，将盛有铝片的坩埚移到本生灯上，加热三分钟； 3．再称坩埚和铝片的重量 实验结果 比加热前略重些 实验结论 铝在空气中加热后，重量会发生变化 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Step 1　审题谋篇·定框架 定人称 以第三人称为主 定时态 以一般现在时为主 定框架 第一段：实验目的和器材； 第二段：实验步骤； 第三段：实验结果和结论 Step 2　要点翻译·用佳句 1．我们今天做了一个实验。实验的目的是要探究铝加热时重量是否有变化。 Today we carried out an experiment．Its aim was to find out if there was a change in weight when aluminium was heated. [升级]　用定语从句改写句1 The aim of the experiment we made today was to find out if there was a change in weight when aluminium was heated. 2．为了进行实验，我准备了以下设备：铝片、本生灯、天平、坩埚和钳子。 To carry out the experiment, I prepared the following equipment: pieces of aluminium, a Bunsen burner, a balance, a crucible and a pair of tongs. 3．我们把铝片放进坩埚里。 We put the pieces of aluminium into the crucible. 4．然后我们把坩埚放在天平上称了称。 Then we put the crucible on the balance and weighed it. 5．我们点燃了本生灯。 We lighted the Bunsen burner. 6．我们把盛着铝的坩埚放在本生灯火焰上。 We held the crucible with aluminium in it over the Bunsen burner flame. 7．我们把装有铝的坩埚放在天平上，再称一次。 We put the crucible with the aluminium in it on the balance and weighed it again. 8．我们发现它比以前重了一点。 We found it weighed a little more than before. 9．我们得出的结论是铝加热时重量有变化。 In conclusion, there was a change in weight when aluminium was heated. [升级]　用同位语从句改写句9 We drew a conclusion that there was a change in weight when aluminium was heated. Step 3　连句成篇·达美文 The aim of the experiment we made today was to find out if there was a change in weight when aluminium was heated.To carry out the experiment, I prepared the following equipment：pieces of aluminium, a Bunsen burner, a balance, a crucible and a pair of tongs. The steps were as followed.First, we put the pieces of aluminium into the crucible.Then we put the crucible on the balance and weighed it.Next, we lighted the Bunsen burner.After that，we held the crucible with aluminium in it over the Bunsen burner flame.Finally, we put the crucible with the aluminium in it on the balance and weighed it again.We found it weighed a little more than before. We drew a conclusion that there was a change in weight when aluminium was heated. 人物 描写 ①capable 　　 adj.有能力的 ②brilliant adj.聪颖的，才华横溢的 ③biologist n．生物学家 ④never say never 　　 别轻易说决不 ⑤be lost 迷路 ⑥beyond description 无法用语言描述 动作 描写 ①shoot v.拍摄 ②injure v．使受伤，弄伤 ③flash n.闪光 ④attach v．系，绑；贴 环境 描写 ①species n.物种 ②battery n．电池 ③compass n.指南针，罗盘 ④stuff n．东西，物品 [语段情景用]　生物学家蒂姆对森林中的稀有物种感到兴奋和惊讶，他沉浸在拍摄它们的照片中。当他的手机电池没电时，他才意识到自己在森林中迷路了…… Excited and surprised at the rare species in the forest，Tim，1.a biologist (一名生物学家)，was absorbed in 2.shooting their pictures (拍摄它们的照片).It was when his cellphone battery ran out that he realized that he was lost in the forest.Without a compass or a map，he thought he 3.wasn't capable of walking out (无法走出去).What's worse，he tripped and 4.his leg was injured (腿受伤了).After numerous attempts and failures，he saw the flash on the main road.At that moment，he 5.was excited beyond description (激动得无法用语言形容). 学科网（北京）股份有限公司 $$
