Telephone
The telephone (from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice"), often colloquially referred to as a phone, is a telecommunications device that transmits and receives sound, most commonly the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. It is one of the most common appliances in the developed world, and has long been considered indispensable to businesses, households and governments. The word "telephone" has been adapted to many languages and is widely recognized around the world.
All telephones have a microphone to speak into, an earphone which reproces the voice of the other person, a ringer which makes a sound to alert the owner when a call is coming in, and a keypad (or in older phones a telephone dial or no manual device) to enter the telephone number of the telephone being called. The microphone and earphone are usually built into a handset which is held up to the face to talk. The keypad may be part of the handset or of a base unit to which the handset would be connected. A landline telephone is connected by a pair of wires to the telephone network, while a mobile phone or cell phone is portable and communicates with the telephone network by radio. A cordless telephone has a portable handset which communicates by radio with a base station connected by wire to the telephone network, and can only be used within a limited range of the base station.
The microphone converts the sound waves to electrical signals, which are sent through the telephone network to the other phone, where they are converted back to sound waves by the earphone in the other phone's handset. Telephones are a plex communications medium, meaning they allow the people on both ends to talk simultaneously. The telephone network, consisting of a worldwide net of telephone lines, fiberoptic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows any telephone in the world to communicate with any other. Each telephone line has an identifying number called its telephone number. To initiate a telephone call, a conversation with another telephone, the user enters the other telephone's number into a numeric keypad on his/her phone. Graphic symbols used to designate telephone service or phone-related information in print, signage, and other media include ℡ (U+2121), ☎ (U+260E), ☏ (U+260F), and ✆ (U+2706).
Although originally designed for voice communication, the system has been adapted for data communication such as Telex, Fax and dial-up Internet communication.

Harvard University is a private Ivy League university located in Cambridge, Massachusetts, United States, established in 1636 by the Massachusetts legislature. Harvard is the oldest institution of higher learning in the United States[6] and the first corporation (officially The President and Fellows of Harvard College) chartered in the country. Harvard's history, influence, and wealth have made it one of the most prestigious universities in the world.[7][8]
Harvard was named after its first benefactor, John Harvard. Although it was never formally affiliated with a church, the college primarily trained Congregationalist and Unitarian clergy. Harvard's curriculum and students became increasingly secular throughout the 18th century and by the 19th century had emerged as the central cultural establishment among Boston elites.[9][10] Following the American Civil War, President Charles W. Eliot's forty year tenure (1869–1909) transformed the college and affiliated professional schools into a centralized research university, and Harvard became a founding member of the Association of American Universities in 1900.[11] James Bryant Conant led the university through the Great Depression and World War II and began to reform the curriculum and liberalize admissions after the war. The undergraate college became coecational after its 1977 merger with Radcliffe College. Drew Gilpin Faust was elected the 28th president in 2007 and is the first woman to lead the university. Harvard has the largest financial endowment of any academic institution in the world, standing at $27.4 billion as of September 2010.[3]
The university comprises eleven separate academic units — ten faculties and the Radcliffe Institute for Advanced Study — with campuses throughout the Boston metropolitan area.[12] Harvard's 210-acre (85 ha) main campus is centered on Harvard Yard in Cambridge, approximately 3.4 miles (5.5 km) northwest of downtown Boston. The business school and athletics facilities, including Harvard Stadium, are located across the Charles River in Allston and the medical, dental, and public health schools are located in the Longwood Medical Area.[5]
As of 2010, Harvard employs about 2,100 faculty to teach and advise approximately 6,700 undergraates (Harvard College) and 14,500 graate and professional students.[13] Eight U.S. presidents have graated from Harvard and 75 Nobel Laureates have been affiliated with the university as students, faculty, or staff. Harvard is also the alma mater of sixty-two living billionaires, the most in the country.[14] The Harvard University Library is the largest academic library in the United States, and the third largest library in the country.[15]
The Harvard Crimson competes in 41 intercollegiate sports in the NCAA Division I Ivy League. Harvard has an intense athletic rivalry with Yale University traditionally culminating in The Game, although the Harvard–Yale Regatta predates the football game.
C. 电话的发明作文100字
例文
如今，电话走进了千家万户，你知道电话是谁发明的吗？
贝尔，就是发明电话的人。他年生于英国，年轻时跟父亲从事聋哑人的教学工作，曾想制造一种让聋哑人用眼睛看到声音的机器。
1873年，成为美国波士顿大学教授的贝尔，开始研究在同一线路上传送许多电报的装置——多工电报，并萌发了利用电流把人的说话声传向远方的念头，使远隔千山万水的人能如同面对面的交谈。于是，贝尔开始了电话的研究。
那是1875年6月2日，贝尔和他的助手华生分别在两个房间里试验多工电报机，一个偶然发生的事故启发了贝尔。华生房间里的电报机上有一个弹簧粘到磁铁上了，华生拉开弹簧时，弹簧发生了振动。与此同时，贝尔惊奇地发现自己房间里电报机上的弹簧颤动起来，还发出了声音，是电流把振动从一个房间传到另一个房间。贝尔的思路顿时大开，他由此想到：如果人对着一块铁片说话，声音将引起铁片振动；若在铁片后面放上一块电磁铁的话，铁片的振动势必在电磁铁线圈中产生时大时小的电流。这个波动电流沿电线传向远处，远处的类似装置上不就会发生同样的振动，发出同样的声音吗？这样声音就沿电线传到远方去了。这不就是梦寐以求的电话吗！
贝尔和华生按新的设想制成了电话机。在一次实验中，一滴硫酸溅到贝尔的腿上，疼得他直叫喊：“华生先生，我需要你，请到我这里来！”这句话由电话机经电线传到华生的耳朵里，电话成功了！1876年3月7日，贝尔成为电话发明的专利人。
贝尔一生获得过18种专利，与他人合作获得12种专利。他设想将电话线埋入地下，或悬架在空中，用它连接到住宅、乡村、工厂……这样，任何地方都能直接通电话。今天，贝尔的设想早已成为现实。

Today, the phone into the tens of thousands of households, do you know who invented the telephone?
Baer, who is the inventor of the telephone. He was born in the UK in 1847, when young, with his father in deaf ecation, had wanted to make a kind of let the deaf use the eyes to see the sound machine.

It was in June 2, 1875, Baer and his assistant Watson respectively in the two room test multiple telegraph, an accidental incidents inspired Baer. Watson room Telegraph has a spring stick to the magnet, Watson opened the spring, spring has vibration. At the same time, Baer was surprised to find his room telegraph machine on the spring vibration, also makes a sound, is the current vibration from one room to another room. Baer's idea was wide open, he thus think: if people on the piece of iron to iron, sound will cause vibration; if the iron is placed behind a piece of magnet, iron sheet vibration inevitably in the electromagnet coil to generate big small current. The fluctuation of current along the wire to the distant, distant similar device does not happen the same vibration, do the same thing? That sound along the wire spread far away. This is not the dream of phone!
Baer and Watson by new ideas made the telephone. In one experiment, a drop of sulfuric acid splashed onto Baer's lap, hurts him shouting:" Mr. Watson, I need you, please come here!" This sentence by telephone through a wire to Watson 's ears, call success! In March 7, 1876, Baer became the invention of the telephone patent.
The life of Baer received 18 patents, and cooperation with others obtained 12 patents. He conceived of telephone lines are buried underground, or suspension in the air, it is connected to the housing, villages, factories ... ... In this way, any place can directly call.
