科学家发明有用东西英语作文

『壹』 假设你的理想是成为一个发明家 谈谈你将发明什么东西 英语作文

童年的我是多么天真，多么幼稚。而我从来没有想过我的理想是什么。我一天天成长，一天天成熟，开始顾及到我的理想。我很想做一个天文科学家。可是那些大科学家，大多数都住在出名的大城市，而我住在这个不太出名的城镇里，纵有雄心壮志，也很难实现。理想对于我来说，是那么遥远、神秘……
科学家，是一个不平凡的职业。像爱因斯坦、伽利略、牛顿那样的科学家，对科学界有很大的影响。我十分佩服他们，因此，我想做一个天文科学家，在火星上发现生物，观察遥远的星球，到真空的宇宙探索……
我一天天地长大，学的知识一天天多起来。我了解了“唐太宗、刘备、康熙……”这些伟大的人物，这使我学会了许多做人的道理。成功，是努力、坚持、天赋组成的，所以我又创出这样一条公式：实现理想=努力+坚持+天赋。一个人如果有了理想，有从小培训的天赋，努力不懈地去实现，失败了，继续坚持，那么理想才会实现。
我从书本上知道，有生命的星球必须有以下条件：1、有坚硬的外壳； 2、有生物生存的适当的温度 ；3、有适当的大气（大部分是氧气）； 4、有足够的水； 5、这也必须是一颗行星，围绕着的中心天体必须是一颗稳定的中年恒星。生命存在的条件是非常苛刻的。我曾经痴迷地想象：“火星上会不会有生物呢？有生物的星球是怎样的呢？会不会是……”我很想揭开这个迷，因此，我很想做一个天文科学家，去发现人类的另外一个家园，去解答宇宙的不解之迷。
我当然知道做一个天文科学家并不容易，要有很高的学历，有很强的求知欲、想象性，还要有一种不怕困难、失败的精神。 “一个小孩想当天文科学家，未免太天真了吧！”不错，听起来的确很天真，但我深信，“只要有恒心，铁柱磨成针”。
为了实现这个理想，我花了不少努力。我购买了《神奇的地球》、《宇宙的奥秘》、《宇宙之迷》……每一本书我都把它读熟透，吸取里面所有的知识。有一次，我从中午开始读书，觉得读了不久，爸爸就叫我下去吃饭了。我十分奇怪，望望屋外面，原来已经是黄昏了。我每天就是这样吸收各个方面的知识，使我的理想与现实不断缩短距离。
我不断在生活中吸取经验、知识。在学习上，我认真听课，积极发言；在表演时，我积极当一个小主持；在辩论时，发表自己的意见、理论……等到长大的时候，我将运用这些知识，争取做一个科学家。
“泉水挑不干，知识学不完”，但只要你肯学，再多的知识你也能学到手。“海阔凭鱼跃，天高任鸟飞”我就像一条鱼，在广阔的前途海洋里自由自在地游，选择哪一条前途，是由我自己选择的。但在这个前途海洋，不能全无风波，但我充满信心，我有信心冲破各个难关，去追求我的理想，实现我的理想，为祖国争光！
