❸ 發明水上自行車作文
水上自行車，這項運動適合兩個人玩。而且兩個人腳勁要足，兩個的配合也要默契，我和哥哥就玩了一次。
開始了，我們兩人使勁踏著板，但因節奏不一樣，很難前進，而且還得另外一隻手轉著方向盤。後來，我想了一個辦法，就口令。「一二一，一二一 ```` 」我們踏得快了起來，越踏越有精神，不久就劃到了對岸。劃回來時，我向哥哥提了個高難度的建議：就是不叫口令，按著剛才的感覺來踏。返回了，我能感覺到我們個自在為自己加油，都在心裡叫口令。似乎回來的時間比較快，不一會兒就回到了起點。我們剛想岸上，但阿姨告訴我們是算時間的，共六十分鍾，你們只玩了二十分鍾，再玩一會兒吧！不只怎麼的，有一段勁從我們身上射出來了，接下來的四十分鍾，我們竟然來來回回踏了三次，我真沒有想到自己和哥哥能這么快學會一樣新本領。
我相信每次鍛煉不管成功或失敗，都是一次進步。

❺ 發明神奇的自行車我的夢想作文
二十年後的今天，隨著科學技術的進步，我們的生活發生了翻天覆地的變化。走在平坦寬闊的橡膠板大街上，你會驚奇的發現，我們身邊會出現很多新奇的東西，你看那是多功能汽車，這是百變廚窗，可是，就是自行車的變化不大，我決定發明一種神奇的自行車。你看，這就是我新發明的神奇自行車。這種自行車會給人們，尤其是給學生帶來極大的方便。如果想用自行車，可以把自行車平鋪在地上，一按按鈕，它就會自動膨脹起來，如果不用，可以把氣放掉，疊起來，放入皮兜里。自行車上面有三把充氣椅子，每把椅子外都有扶手。並且，三把椅子周圍還有圍欄。在每把椅子旁邊，都有一個固定的大盒子，用來放東西。如果遇到下雨天，自行車後面會自動冒出一把大傘，為你擋雨。自行車上有自動音樂盒，當你坐在自行車上休息的時候，把你想聽歌曲的名字輸入音樂盒中，就可以聽到悅耳的音樂了。奇怪的是，這種自行車沒有車輪，在車的底部，只有一塊充氣墊板。你可能會感到奇怪，沒有車輪怎麼行駛呀？原來，這種自行車是用按所需來操作的。在自行車行駛的時候，充氣墊底板離地約30厘米左右，如果在路上遇到大石頭等障礙物，只要把手放在音樂盒上一敲，就能增加離地的高度，非常容易地越過障礙物，繼續飛快地前行了。同學們，這種新型自行車不錯吧？它一定會給你們的生活帶來方便的。不過，我現在仍然需要努力學習，爭取使這個夢想早日實現。

❼ 自行車這個發明真棒450字 作文
真正具有現代形式的自行車是在1874年誕生的。英國人羅松在這一年裡，別出心裁地在自行車上裝上了鏈條和鏈輪，用後輪的轉動來推動車子前進。但仍然是前輪大，後輪小，看起來不夠協調，不穩定。
1886年，英國的斯塔利，是一位機械工程師，從機械學，運動學的角度設計出了新的自行車樣式，為自行車裝上了前叉和車閘，前後輪的大小相同，以保持平
衡，並用鋼管製成了菱形車架，還首次使用了橡膠的車輪。斯塔利不僅改進了自行車的結構，還改制了許多生產自行車部件用的機床，為自行車的大量生產利推廣應
用開辟了寬闊的前景，因此他被後人稱為「自行車之父」。斯塔利所設計的自行車車型與今天自行車的樣子基本一致了。
1888年，愛爾蘭的獸醫鄧
洛普，從醫治牛胃氣膨脹中得到啟示，他把家中花園里用來澆水的橡膠管粘成圓形，打足了氣，裝在自行車輪子上，前往參加騎自行車比賽，居然名列前茅，引起了
人們極大的興趣。充氣輪胎是自行車發展史上一個劃時代的創舉，它增加了自行車的彈性，不會因路面不平而震動；同時大大地提高了行車速度，減少了車輪與路面
的摩擦力。這樣，就根本上改變了自行車的騎行性能，完善了自行車的使用功能。由此可知，從18世紀末葉起，一直到20世紀初期，自行車的發明和改進，經歷
了大約200年的時光，有許多人為之奮斗不息，才演變成現在這種騎行自如的樣式。
❽ 我的多功能自行車作文三百字
未來會有多功能自行車嗎？假如有又會是怎麼樣的呢？我覺得應該是...... 未來，只要有了多功能自行車，大家都不會開會放臭屁的汽車了。多功能自行車有許多按鈕∶紅色——接聽電話 綠色——傾聽美妙歌曲 黃色——講故事 紫色——聽收音機 白色——喝飲料〔蘋果味，可樂，雪碧，橙汁。自選〕 黑色——負責早，中，晚的飯菜 大家有可能想不到，假如你想聽歌，那別人也在聽，那不是有噪音風暴了嗎？沒關系，天藍色按鈕只要一按，那歌只有你自己能聽到的。那你假如想吃東西，那車咋開呢？也沒關系，可愛桃紅色按鈕幫你解決問題，只要按了它，自行車就全自動幫你開，吃完了只要再按一下，你就可以自己開了。但是你假如沒有事情也要自行車幫你開的話，它就會半個小時也都沒有功能效果，這樣你就不會缺乏運動啦！ 你是不是覺得這種自行車很好呢？雖然現在還沒有，但我相信很快就會發明出來的！
