Section Ⅴ　Writing——写一篇实验报告 ◎ 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. ◎ 学语言 1．使用动词短语be designed to，表明了实验目的。 2．使用介词including，列举了实验所准备的材料。 3．使用with复合结构，对做实验前的准备工作做了总结。 4．使用first, then, after a few minutes, just at the same time，使实验步骤一目了然。 5．使用强调句型，突出实验所得出的结论。 知结构 介绍实验的目的 描述实验中使用的材料并解释实验步骤 报告结果以及学习成果 [情境任务写作] 假定你是李华，请根据下列表格中的内容写一篇80词左右的实验报告。 实验目的 查明铝(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．点燃酒精灯，将盛有铝片的坩埚移到酒精灯上，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 [仿写程序步骤] 1．一仿结构布局合理 第一段：实验的目的和器材； 第二段：实验步骤； 第三段：实验结果和结论。 2．二仿语言规范美观 ①我们今天做了一个实验。实验的目的是要找出铝加热后重量是否有变化。(carry out) Today we carried out an experiment.

The stages were as follows.First，we put the pieces of aluminium in 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 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 is a change in weight after aluminium is heated. [精彩素材积累] 1．描写实验目的： (1)... carry out an experiment to find out... (2)The aim of the experiment is to find out...

[学以致用] 假定你是李华， 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 ℃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 the 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 to 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 beaker to 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. 40分写作限时练(三) (时间：45分钟　满分：40分) (本栏目内容，在学生用书中以独立形式分册装订！) Ⅰ.应用文写作(满分15分) (2024·汕头期末) 假设你是李华，你将参加学校一年一度的英语演讲比赛，就高中学生对网络游戏上瘾的问题发表演讲，请你根据以下内容写一篇演讲稿。内容包括： 1．描述现象； 2．沉迷网游的危害； 3．发出呼吁。 注意：1.写作词数应为80左右； 2．请按如下格式作答。 Dear fellow students， ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ That’s all.

The next day, Dana brought cupcakes to class.When she handed a cupcake to Tim, she asked if Tim had brought Nezumi to school as Nezumi liked to ride in backpacks.Tim was at a loss because Nezumi was at home on his bed.Then Dana asked what gift he would give her.Tim replied it was a surprise.In silence they sat for a while before he heard Dana say her parents would give her a new bike for her birthday instead of a live rat because they thought rats would bite things. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 At home that afternoon, Tim stared at the plastic ball. _____________________________ ________________________________________________________________________ ________________________________________________________________________ All of a sudden, he had an idea._______________________________________________ ________________________________________________________________________ ________________________________________________________________________ [参考范文] At home that afternoon, Tim stared at the plastic ball.
