Unit3 ALEXANDER GRAHAM BELL 亚历山大·格雷厄姆·贝尔 Alexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA. 亚历山大·格雷厄姆·贝尔 1847 年出生于苏格兰。
但在他还小的时候,他家就搬到了美国 的波士顿。 His mother was almost entirely deaf, so Alexander became interested in helping deaf people communicate and in deaf education. 他的母亲几乎全聋了,因此他有志于帮助聋人交流,并从事聋人教育事业。
This interest led him to invent the microphone. 这一爱好促使他发明了麦克风。 He found that by pressing his lips against his mother's forehead, he could make his mother understand what he was saying. 他发现他把嘴唇放在母亲的额头上, 并以一定的方式来移动额骨, 就可以使她听懂他所说的 话。
He believed that one should always be curious and his most famous saying was: 他认为一个人应该总是有好奇心理。他最有名的一句话是: "Leave the beaten track occasionally and dive into the woods. 偶尔离开平路去寻求困境。
Every time you do you will be certain to find something that you have never seen before. 每次当你这样做的时候,你一定会发现你从未见过的东西。 Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. 跟踪下去,不断探索,不知不觉中,你就会发现某种值得思考的东西盘踞着你的头脑。
All really big discoveries are the result of thought." 所有真正伟大的发现都是思考的结果。 It was this exploring around problems and his dynamic spirit that led to his most famous invention - the telephone in 1876. 正是这种对问题的探索和富有活力的精神造就了他那最著名的发明——1876 年的电话。
Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. 贝尔并非一开始就想要发明电话的,他本来想设计的东西是多路电报。 This original telegraph sent a message over distances using Morse code (a series of dots tapped out along a wire in a particular order). 这种原始的电报是在一段距离中用莫尔斯电码传递信息 (莫尔斯电码是通过电线发出的以特 定的次序敲击出的一连串点划) , But only one message could go at a time. 但是这样只能一次发一个信息。
Bell wanted to improve it so that it could send several messages at the same time. 贝尔想改进电报通讯方式,以便同时能发出好几个信息。 He designed a machine that would separate different sound waves and allow different conversations to be held at the same time. 他设计了一种机器,以使声波分成不同的音调,从而有可能在同一时间里进行不同的通话。
But he found the problem difficult to solve.但是他发现这个问题很难解决。 One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass, 有一天做实验, 他把一根干草的一端和一个聋子的耳鼓膜连接起来, 另一端连接一块被烟熏 过的玻璃。
ALEXANDER GRAHAM BELL He believed that one should always be curious and his most famous saying was: "Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never seen before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought." It was this exploring around problems and his dynamic spirit that led to his most famous invention - the telephone in 1876. Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. This original telegraph sent a message over distances using Morse code (a series of dots tapped out along a wire in a particular order). But only one message could go at a time. Bell wanted to improve it so that it could send several messages at the same time. He designed a machine that would separate different sound waves and allow different conversations to be held at the same time. But he found the problem difficult to solve. One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass, Bell noticed that when he spoke into the ear, the straw drew sound waves on the glass. Suddenly he had a flash of inspiration. If sound waves could be reproduced in a moving electrical current, they could be sent along a wire. In searching to improve the telegraph, Bell had invented the first telephone! Bell was fully aware of the importance of his invention and wrote to his father: "The day is coming when telegraph wires will be laid on to houses just like water or gas – and friends will talk to each other without leaving home." The patent was given in 1876, but it was not until five days later that Bell sent his first telephone message to his assistant Watson. The words have now become famous: "Mr Watson - come here - I want to see you." Alexander Graham Bell was not a man to rest and he interested himself in many other areas of invention. He experimented with helicopter designs and flying machines. While searching for a kite strong enough to carry a man into the air, Bell experimented putting triangles together and discovered the tetrahedron shape. Being very stable, it has proved invaluable in the design of bridges. Bell was an inventor all his life. He made his first invention at eleven and his last at seventy- five. Although he is most often associated with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybody's life.他相信一个人应该永远保持好奇,他最著名的话是:“越雷池一步偶尔和潜水到树林里去了。
你每一次你将某些找到一些你从未见过的。遵循它,探索周围,在你知道之前,你会有一些值得思考来占据你的思想。
所有真正重大的发现都是由于思想”。正是这种探索解决问题和他的动态精神导致了他最著名的发明——在1876年的电话。
贝尔从来没有打算发明电话和他试图设计是一种多个电报。这一最初的电报发送一个消息传输距离使用莫尔斯代码(一系列的点了沿着一条线在一个特定的顺序)。
但只有一个消息可以在一个时间。贝尔希望改善它,这样就可以发送一些消息在同一时间。
他设计了一种机器,能够区分不同声波,允许不同的谈话内容是在同一时间举行。但他发现这个问题很难解决。
一天,他开始尝试使用一根稻草的一端与一个失聪的人的耳膜,另一块烟色玻璃,Bell注意到,当他说到耳朵、稻草德鲁声波在玻璃上。突然他有一个flash的灵感。
如果声波能复制在一个移动的电流,他们可以发送沿着一条线。在寻找改善电报,贝尔发明了第一个电话!贝尔完全意识到他的发明的重要性和写信给他父亲说:"的日子即将来临的电报线路将被放置在到房子就像水或气体——和朋友会彼此交谈不离开家。”
是1876年授予的专利,但直到5天后,贝尔电话消息发送了第一向他的助手沃森。这个词现在已经成为著名的:“华生先生——来这里——我想要见你。”
亚历山大·格雷厄姆·贝尔是一人休息和他自己感兴趣的许多其它领域的发明。他尝试用直升机设计和飞行机器。
在寻找一个风筝强大到足以让人到空中,贝尔尝试把三角形在一起,发现了四面体的形状。非常稳定,它已被证明在设计桥梁的无价。
贝尔是一位发明家他所有的生活。他让他的第一个发明十一点和他去年在七十五岁。
虽然他常伴随着电话的发明,他确实是一个实用的解决方案后,继续搜索改善每个人的生活质量 翻译完毕 如果有帮到您,请采纳,点击【采纳为满意答案】按钮即可,如果还有问题 请发帖重新提问哦 谢谢拉#^_^#祝您学习愉快。

答案是: 第三单元主要讲述的是 形容词的比较级的用法 比较级构成是: 1.一般情况下在后面直接加上er shorter 2.以不发音的e结尾的单词加上 r 如:nice--nicer 3.以辅音字母结尾的加上y结尾的单词,变 y 为 i 再加上 er lazy--lazier 4.以重读闭音节结尾的单词双写辅音字母加上er 如:big--bigger 5.部分双音节和多音节单词在前面加上 more,如:interesting--more interesting 用法: 同级比较:1.“as+adj/adv+as或not so(as)+adj/adv+as.”句型。
该句型常用来描述两个比较对象的程度上的相似或不同(即平时说的“等级比较和不等级比较”)。 如:he is as tall as I 他和我一样高 比较: 1.用于两者比较的选择疑问句 who is taller ,Tom or Jim ? 2.用于下列句型: 主语(be动词)+形容词比较级 +than +比较对象 he is more outgoing than I 主语+行为动词+副词比较级 +than +比较对象 he runs faster than I 3.比较级+and+比较级 表示:越来越。
it's geting colder and colder 4.用于两者中的一个:较。 用:the +比较级 Lucy is the taller of the twins 露西是双胞胎中较高的那个 暂时先告诉你这么多,以后还有更多的再给你讲述 ☞ ♧手工翻译☀尊重劳动☀欢迎提问☀感谢采纳♧ ☜。
