英文读后感 On Science 读后感作文
王乙锟 北京一零一中学高一阅读书目：国家地理科学探索丛书 物理科学系列：《力与运动》《走进电的世界》生命科学系列：《你和你的基因》《观察细胞》《保护地球母亲》
I have got a lot of interesting scientific knowledge from the books of National Geographic Reading Expeditions, some of which are about life, physics. I really can’t help losing myself in the colorful pictures and clear words in the books. After reading the books, I have been considering a question: What if we lived without science?
Great changes have taken place in the world with the help of science. In the past, life was nasty, brutish and short. It is hard to imagine how our forefathers could do without so many conveniences that modern science brings about. Back then, only a small group of people enjoyed the very few comforts. But the majority of people didn’t even have sufficient food, let along their privilege to be educated. Anyway, it is science that changes the world and makes people’s life better and better, although it also leads to some bad aspects at the same time.
From the discovery of the gravity to the first step on the moon, we human beings have experienced a long process of developing science. And now, this process is still continuing much faster. New organisms are already being engineered, and new genetically modified crops promise benefits from higher yields and less use of harmful chemicals and so on. A lot of examples are showing this point. In the future, changes are likely to be even much greater as science reaches out to shape life itself. Maybe one day, the possibility that life existed on Mars billions of years ago will be potentially one of the greatest discoveries of our time. It is the force of the competition, we human beings’ inquiring mind and initiative that bring about the non-stopped development of science. Therefore, it is difficult and impossible to prevent science from changing the world and our life as well.
At present, we are in two minds about science. On the one hand, we are enjoying the sweet life as a result of the evelopment of science, and expect it to continue. And we are showing our interests into some scientific expeditions, such as the astronomy, the alien civilization, etc. On the other hand, we are distrustful of it, due to the lack of understanding of science. Some people thus far are still very superstitious, and they would even believe in superstitions rather than believe in science.
Stephen Hawking, one of the most remarkable scientists in the world, once said, “In a democratic society, the public needs to have a basic understanding of the science, so that it can make informed decisions and not leave them in the hands of experts.” This has reminded me of Professor Alan G. MacDiarmid from America, the person who got the Nobel Prize for chemistry in the year of 2000. In his lecture at Peking University this year, he put forward that science is people. He also expounded the importance of the basic science for the public. Evidently, every one of us does need science, or we can’t live without it.
Now that everyone needs science, why not take advantage of some means to give the public the right basic scientific knowledge? So when they face the problems such as acid rain, the greenhouse effect, nuclear weapons, environment destruction and some other problems, they can also make informed decisions on these subjects, just as what Hawking said. One aspect relies on what is taught in schools. But science is often taught in an uninteresting way and most students just learn it by rote to pass examinations. However, the final goal of learning science is not to pass examinations or to get a higher score; instead, we should try to make full use of it to change our world and life. While learning, we should try to ask more questions and we should have the courage of suspecting the knowledge in the books, as some of the scientific conclusions are likely to be corrected in the future. Who knows. So not only must we change our attitude towards science, but also the way of teaching and learning science.
In addition, science is always changing at a fast rate, and who we learn at school isn’t that sufficient to last a lifetime. So the mass media including TV, radio, newspaper, magazine and publishing company will play an important role in reporting the latest science in time. Moreover, the mass media can also popularize basic science to the public, because only in this way will more people realize what on earth science is.
“Scientists and engineers tend to express their ideas in the form of equations because they need to know the precise values of quantities. But for the rest of us, a qualitative grasp of scientific concepts is sufficient, and this can be conveyed by words and diagrams, without the use of equations”, said Stephen Hawking.
I agree with him very much, and, I’m fond of the wonderful words above, from Stephen Hawking.
For the development of science, are you ready?
《简·爱》读后感
读《简·爱》有感在我的心目中，《简·爱》是一部完美而伟大的著作，因为它使我懂得了什么是善恶美丑，学会了怎样做人，而书中的主人公简·爱就是我学习的榜样，她的聪明、善良、坚强、有主见，是最令人敬佩的。简·爱的一生悲欢离合。她遭遇了许多挫折和坎坷，可以说是不幸的，但是她却从不向命运低头，任何困难在她面前都会感到恐惧。简·爱从小被她的舅妈收养，受尽了她的虐待。而且她舅舅的儿子约翰里德还是一个又胖又大、蛮横无理、猪狗不如的禽兽。他经常无缘无故地打骂简·爱，但她的舅妈不但不去制止，反而支持她野蛮的儿子。然而，简·爱是一个顽强的、决不向恶势力低头的人。她再也忍受不了了，她对约翰的恨压倒了对他的畏惧，不顾一切地跟他对打起来。当然，结果可想而知，简·爱受到了她舅妈的惩罚。但她的这次举动足以令约翰胆颤心惊。
简·爱说过这样的一段话，给我的印象很深，也很能体现她的性格。她说：“如果大家老是对残酷，不公道的人百依百顺，那么那些坏家伙就更要任性胡来了，他们会什么也不惧怕，这样也就永远也不会改好，反而越来越坏，当我们无缘无故挨了打，我们一定要狠狠地回击。”我很赞成简的这种说法，因为自尊、自重是做人的最起码的要求。
但是海伦·彭斯，她的观点与简是截然不同的。海伦主张凡事能忍就忍，这样自己快乐，别人也会对你好一些。我觉得海伦的这些话在我们看来是很让人不可理解的。但是她的宽容、忍让以及她那博大的胸怀，是令人钦佩的。我们无需去评价她的话，至少我们应从中悟出些什么。我很喜欢海伦的一句话：“我觉得生命太短促了，不值得把它花费在怀恨和记仇上。”只要我们每人都能记住它，多多去理解别人，体谅别人，关心别人，多看到一些美好的事物，乐观地对待生活，我们的生活中一定会充满阳光。
我认为罗切斯特先生，正是她生活中的阳光。他们两人的交往是愉快的；他们两人的对话又是耐人寻味的。因为他们各自的性格特点都在那简短的对话中表现得淋漓尽致。
罗切斯特先生是一个正直、善恶分明而又带有幽默感的人。他们两人真心相爱了。然而在他们的婚礼上，梅森先生揭露了罗切斯特先生是个有妻之夫的秘密后，简彻底失望了，她怀着万分悲痛的心情离开了他。然而他们最终又走到了一起。
时间会消除报复的渴望，平息愤恨和憎恶的冲动。简·爱曾经是带着满腔怨恨离开她舅妈的，但当她听说里德太太生命垂危，又很想见她一面的时候，简忘却了她的一切不好，毫不犹豫地回到了她曾经厌恶的地方。当她见到里德太太时，简所剩的都是对她的怜悯之情。但是里德太太告诉了她一件很重要的事：在三年前，简的叔叔给她写了一封信，想让她继承他的遗产，因为他无儿无女，所以想收简为养女，但是因为里德太太当时对她厌恶至极，也不想让她走远，过上富日子。所以她给简的叔叔回了一封信，说简在洛伍德生伤寒病死了。就这样，简·爱失去了一个转变自己命运的好机会。里德太太的这种行为是很令人气愤的，然而简却没有计较这件事，还不住地安慰里德太太，让她把这些事都统统忘掉，而且简很希望能与她和解，但直到死她也没能改变她对简的态度，这使简无奈而又痛苦。
然而通过这件事，简·爱在我心目中的形象更加高大起来了。简·爱的身上到处都有闪光点。她善良而又宽容，那种视金钱如粪土的精神，更是当今社会的人所应该学习的。
《简·爱》这本书能够照出我们身上的不足，让我们找到正确的人生方向，把曾经失去的东西找回来。让我们有信心、有勇气去面对困难，并且战胜困难，为我们的人生添上绚丽的一笔。
