Period 4　Writing 写作一　应用文写作(实验报告) 请根据下面表格中的内容写一篇实验报告。 实验目的 测量镁在空气中加热后重量是否有变化 实验用品 镁(magnesium)、本生灯(Bunsen burner)、秤(balance)、坩埚(crucible) 实验步骤 1.把镁放进坩埚内； 2.把坩埚放在秤上称重； 3.点燃本生灯，加热坩埚中的镁； 4.把坩埚放在秤上称重； 5.比较两次称重的结果 实验现象 第二次称重数据大于第一次称重数据 实验结论 镁在空气中加热后重量有变化 注意：写作词数应为80个左右。 　审题谋篇 　遣词造句 1．find_out　　　　　 弄清 2．experiment n. (科学)实验 3.conduct v. 实施，进行 [第一段]　实验目的 1．这个实验的目的是弄清楚镁在空气中加热后重量是否会发生变化。 The aim of the experiment is to_find_out_if_there_is_a_change_in_weight after magnesium is heated in air. [第二段]　实验用品、实验步骤 2．你需要以下这些东西来进行实验。这些东西是镁、本生灯、秤和坩埚。 You need the following things to_conduct_the_experiment． Things are magnesium, a Bunsen burner, a balance and a crucible. 3．所有这些准备好，你就可以开始实验了。(with复合结构) With_all_these_ready,_you can begin the experiment. 4．把镁放入坩埚中。将坩埚放在天平上并称重。 Put the magnesium in the crucible. Then put_the_crucible_on_the_balance_and_weigh_them． 5．点燃本生灯，把坩埚放在灯上加热镁。 Light the Bunsen burner and place_the_crucible_over_it_to_heat the magnesium. 6．再次称重，并比较两次的重量。 Weigh them again, and compare_the_two_weights． [第三段]　实验现象和实验结论 7．你会发现镁比之前稍微重了一些。 You can see the magnesium weighs a_little_more_than_before． 8．所以，你会得出结论——镁在空气中加热后重量发生了变化。(that引导同位语从句) So you can draw a conclusion that_there_is_a_change_in_weight after magnesium is heated in air. 9．用主语从句改写句2 What_you_need_to_conduct_the_experiment_is_the_following_things:_magnesium,_a_Bunsen_burner,_a_balance_and_a_crucible. 　衔接成篇 ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ One possible version： The aim of the experiment is to find out if there is a change in weight after magnesium is heated in air. What you need to conduct the experiment is the following things: magnesium, a Bunsen burner, a balance and a crucible. With all these ready, you can begin the experiment. First, put the magnesium in the crucible. Then put the crucible on the balance and weigh them. Next, light the Bunsen burner and place the crucible over it to heat the magnesium. Finally, weigh them again, and compare the two weights. You can see the magnesium weighs a little more than before. So you can draw a conclusion that there is a change in weight after magnesium is heated in air. 假定今天你们在物理老师的帮助下做了一个有趣的实验。请根据以下实验步骤，用英语写一篇80词左右的实验报告。 1．准备一支蜡烛、一个盆、一些水，还有一个比蜡烛稍高些的玻璃杯； 2．将蜡烛置于盆底，并向盆中倒入一些水； 3．点燃蜡烛，将玻璃杯罩在蜡烛上； 4．当蜡烛熄灭后，看到玻璃杯中水面高于盆中水面。 参考词汇：盆(basin) ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ One possible version： Today, with our physics teacher's help, we carried out an interesting experiment in class.
