Until now, the mobile phone become a very important tool in people life, and like a Swiss army knife is versatile.贝尔发明电话英语作文篇6Telephones are so popular in the world that nearly every family has a telephone. They play an important part in our daily life.We can use it to deal with our affairs easily. And mobile phones are the most popular. But some students in our school also have mobile phone. I think it is not good for students to have a mobile phone. On one hand, it will use money. On the other hand, it will bad for the students to have lessons. They can’t concentrate on their lessons.What do think about it?贝尔发明电话英语作文篇7I was tired with preparing for the Joint College Entrance Examination the other evening. And having been alone forseveral hours, I was eager to have someone to chat with me about anything but examinations. So I telephoned my best friend Mary, who was also busy preparing for the joint entrance examination.On the telephone, I told her that I missed her very much.

For another, it can make the students fashionable and proud.On the other hand, mobile telephone has a negative effect on the students. First , it will cost them more money than before. Second, it will distract them from their study. Third, it will sometimes become a nuisance especially when it rings in class or in the library.In my opinion , it is not good for the students on campus to use mobile telephone . Since the student s’ main purpose on campus is to study , they should pay much attention to their study. If they want to use mobile telephone , they can use it after graduation.贝尔发明电话英语作文篇9The day before Mother’s Day, everybody around me was talking about what gift would they buy to their beloved mothers. Buying flowers is what most students will do, others buy chocolates. While for me, I want to do something different, as I live in school and can’t go back home on Mother’s Day, I decide to make a call to her, sending her my warmest wishes. I am so nervous now and have no idea what to say. I search the Internet for some suggestions, it is very useful for me, many wonderful words are presented in front of my eyes. I read them one by one. As I decide to copy these words, suddenly I feel there is no meaning for saying someone else’s words. So I give up, I will tell my mother that I love her and thank you for the things she has done for me.贝尔发明电话英语作文篇10Communication is very important both in the past and at present, and it tends to be more essential in modern society. Telephone and letter are two main means of communication, and they both have their advantages and disadvantages.Communication with other people by telephone is very convenient, especially when you have something urgent. For example, if one of your family members is seriously ill at night, and you don't know how to deal with it and where to find a doctor or a taxi. A telephone is the answer. Dial 120 and you will get services from the doctor very soon. In addition, with the quick rhythm of life, people usually don't have as much time to write letters as before, again telephone solves the problems. Friends can chat through the wire. It seems that telephone shortens the distance between people. Men can keep in touch with each other more easily.However, still some people prefer writing letters to communicate with friends. First, sending a letter is much cheaper than having a telephone call. Second, people can not only greet each other but also exchange their thoughts in letters. Because when a person writes, he must organize his mind and express his ideas and feelings more logically, while telephone often makes people lazy. Finally, people easily keep secret in the letter and say whatever you want to say, while they sometimes can't do that in a telephone.In my opinion, you can combine these two ways together: some unimportant things can be expressed by a telephone, while some important or unspoken things can be done by a letter.贝尔发明电话英语作文篇11The telephone is one of the most welcome and useful inventions. No wonder more and more families have got to use their own telephones today.The telephone makes things easy in many ways.Especially, after the mobile telephone appears, communication becomes easier and rapider.To students and people going out for business far away from their homes, the telephone can shorten the distance between them and their families.

Quite a few use them at school to keep in touch with their families and friends instead of writing letters, which, of course brings convenience to them. But I don't think it's good to do so.In spite of the advantage mentioned above, student users often waste a lot of time chatting over the phone in their spare time, some even use them to cheat in exams. In addition, mobile phone bill is also a heavy burden on students' families.。

谁发明了电话英语作文

谁发明了电话英语作文

谁发明了电话英语作文Alexander Graham Bell: The Inventor of the Telephone.The telephone has revolutionized the way we communicate and connect with the world. Before its invention, long-distance communication was limited to letters, telegraphs, and face-to-face interactions. Today, the telephone has become an indispensable part of our lives, allowing us to stay in touch with family, friends, and colleagues regardless of their location.The invention of the telephone is attributed to Alexander Graham Bell, a Scottish-born inventor and scientist. Bell's fascination with sound and communication began at an early age. His father, Alexander Melville Bell, was a renowned elocutionist who developed a system called Visible Speech, which represented speech sounds using symbols. Bell's mother, Eliza Grace Symonds, was deaf, which further fueled his interest in finding ways to improve communication for the hearing impaired.In 1870, Bell moved to Boston, Massachusetts, to pursue his education at Boston University. While there, he became acquainted with Thomas A. Watson, an electrician who would later become his assistant and collaborator. Together, they experimented with various methods of transmitting sound over wires.One of Bell's early breakthroughs came in 1874 when he developed a device called the "harmonic telegraph." This device allowed multiple telegraph messages to be transmitted simultaneously over a single wire. However,Bell soon realized that the harmonic telegraph could also be used to transmit sound.On March 10, 1876, Bell uttered the first intelligible words over a telephone: "Mr. Watson, come here; I want to see you." Watson, who was in the next room, heard Bell's voice clearly through the receiver. This historic event marked the birth of the telephone.Bell's invention quickly gained widespread recognitionand acclaim. In 1877, he founded the Bell Telephone Company, which would later become AT&T. Over the next few decades, Bell's telephone underwent significant improvements, including the development of the carbon microphone, the rotary dial, and the automatic telephone exchange.Bell's invention had a profound impact on society. It facilitated long-distance communication, enabled businesses to operate more efficiently, and fostered the growth of new industries and technologies. The telephone also played a critical role in both world wars, allowing military commanders to communicate and coordinate their forces.In addition to his work on the telephone, Bell also made significant contributions to other fields, including aeronautics, medicine, and education. He founded the Volta Laboratory, a research facility where he and his associates conducted pioneering experiments in electricity, sound, and aviation.Bell's legacy extends far beyond his invention of the telephone. He was a brilliant inventor, scientist, andhumanitarian who dedicated his life to improving communication and advancing human knowledge. His contributions have had a lasting impact on the world, and his name remains synonymous with innovation and discovery.Here are some additional facts about Alexander Graham Bell and the invention of the telephone:Bell was not the only person working on the telephone at the time. Several other inventors, including Elisha Gray and Thomas Edison, were also experimenting with similar devices. However, Bell is generally credited with being the first to develop a practical and commercially viable telephone.The first telephone conversation between two cities took place in 1878 between Boston and Salem, Massachusetts.The first international telephone call was made in 1881 between New York City and London.The first transatlantic telephone cable was laid in1956, connecting North America and Europe.Today, there are over 1 billion telephone lines in use worldwide, and the telephone remains one of the most important and widely used communication technologies.。

The telephone was invented by Alexander Graham Bell in 1876. Bell was a Scottish-born inventor and scientist who was living in Canada at the time. He was working on a device that could transmit sound over a wire, and he succeeded in creating the first working telephone.The telephone works by converting sound waves into electrical signals that can be transmitted over a wire. When you speak into a telephone, your voice causes a diaphragm to vibrate, which in turn creates an electrical signal. This signal is then transmitted over a wire to the receiver on the other end, where it is converted back into sound waves and heard as your voice.The telephone has had a profound impact on society. It has made communication faster and more efficient, and has allowed people to stay in touch with each other even when they are far apart. It has also created new industries, such as the telecommunications industry, and has led to the development of new technologies, such as the internet and mobile phones.Overall, the invention of the telephone has had a transformative effect on human society, and has paved the way for countless other technological advances.中文:电话的发明是人类历史上最重要的里程碑之一。

The Telephone
The telephone may seem like a complicated machine, but it really is one of the simplest devices that you may find in your home, or anywhere else you can imagine.
