I'm very happy to introduce our school's lab to you.,Before doing any experiments， there are a few laboratory safety rules that we must remember. Firstly， the most important thing is that we should conduct ourselves in a responsible manner at all times in the laboratory. As you see， the students should follow teachers' instructions carefully. If we do not understand a direction or part of a procedure， we need to ask our teacher before proceeding with the activity. Also， students should not touch any equipment， instruments， or other materials in the laboratory area until we are instructed to do so. When leaving the laboratory students should put back all the instruments and keep the laboratory clean and tidy. Lastly， close all the windows and lock the doors of the lab.‎ ‎ 高频单词 ‎1．expand (v.) 膨胀；扩大；增加 ‎2．contract (vi.) 收缩 ‎3．stage (n.) 阶段；时期 ‎4．boil (v.) 煮；煮沸 ‎5．ordinary (adj.) 普通的；平常的 ‎6．float (vi.) 漂浮 ‎7．form (v.) 形成 ‎8．balance (n.) 天平→balanced (adj.) 平衡的 ‎9．mixture (n.) 混合物→mix (vt.) 混合 ‎10．conclusion (n.) 结论→conclude (v.) 下结论 ‎11．aim (n.&v.) 目标；目的；以……为目标→aimless (adj.) 漫无目的的 ‎12．electrical (adj.) 与电有关的；用电的→electricity (n.) 电→electric (adj.) 电的 ‎13．equipment (n.) 设备；装备→equip (vt.) 装备；配备 ‎14．react (vi.)
