初二3班 技术课 用电烙铁焊接制作收音机
初二3班的技术课上,同学们正在进行收音机制作。没有空调的技术教室,在暑气渐消、寒意未至的这个时节,正是最舒适的时候。
同学们手握电烙铁,把电子元件一个一个地焊接到电路板上。他们一边对照说明书确认元件的位置,一边轻轻地将烙铁头贴上去,专注的神情从手上的动作中就能感受到。电烙铁温度很高,大家都借助烙铁架,小心谨慎地进行操作。
如今的收音机还带有蓝牙功能,让人不禁感叹时代的变化。在我上中学的大约40年前,收音机就真的只是"收音机"而已。一点一点地转动调频旋钮,在"沙沙"的杂音另一端终于传来人声的那一刻,那份喜悦我至今仍记忆犹新。
当自己亲手组装的作品里传出声音的那一刻,一定格外令人激动。如果能做出满意的作品,那该多开心啊!期待大家的完成之作。

Year 8, Class 3 Technology Lesson: Building Radios with Soldering Irons
In their technology lessons, pupils in Year 8, Class 3 are working on building radios. With no air conditioning in the technology room, this time of year is the best of all: the summer heat has faded, and the cold has yet to set in.
Using soldering irons, pupils attached electronic components to their circuit boards one at a time. Checking the instructions to line each part up in the right place, they touched the tip of the iron down gently, and their concentration showed in every movement of their hands. As the irons get very hot, they made use of the soldering stands and worked with care.
Today’s radios even come with Bluetooth, which really shows how times have changed. When I was at junior high school around forty years ago, a radio was simply a radio and nothing more. I can still remember turning the dial little by little, and the thrill of hearing a voice come through from somewhere beyond the crackle and hiss.
The moment sound first comes out of something you have put together with your own hands must be truly special. It will be wonderful if everyone ends up with something they are proud of. We are looking forward to seeing the finished radios.
