    我的電信之旅作文450字

    發布時間:2018-06-07 09:00:26    作者:胡子慕

      “太好了,太好了!學校又要組織小記者活動啦!”終于盼來了星期四下午,我們學校三年級小記者的電信局之旅正式開始!

      下了公交車,來到電信局門口,我就看見有叔叔阿姨在等待著我們,他們可真熱情啊!觀摩了營業廳之后,我們興匆匆地跟隨一位叔叔去機房參觀。機房大樓有四層,一樓是一個擺放著無數卡件的大廳,用來盛放電線。二樓是電線的中心集結處。三樓是中心控制廳,最為重要。四樓是一個大型會議室。每到一層,叔叔都耐心地給我們作介紹。而我們每個小記者呢,都認真地聽著,及時地記著。我還提了好幾個問題,了解到了更多知識呢!

      令我印象最深刻的就要數電信發展的過程了。叔叔說,從一開始的液體發射機,到后來的傳呼機,再到“大哥大”,最后到今天的智能手機,電信的傳播方法先進了許多,傳播速度更是快上了幾十倍。看來,電信的發展多么迅猛啊!

      半天的電信之旅很快就結束了,但我的收獲卻不少。我不僅了解了電信的發展過程,還學到了很多書本上沒有的知識。原來,我們的生活變得這樣方便、快捷,是無數人努力的結果。現在,我可以美美地享受生活,更要用心學習,將來也去開創更加美好的生活。
