2021年3月27日雅思阅读真题+题目+答案：The History of building Telegraph lines

A

The idea of electrical communication seems to have begun as long ago as 1746 when about 200 monks at a monastery in Paris arranged themselves in a line over a mile long, each holding ends of 25 ft iron wires. The abbot, also a scientist, discharged a primitive electrical battery into the wire, giving all the monks a simultaneous electrical shock. “This all sounds very silly, but is in fact extremely important because, firstly, they all said ‘ow’ which showed that you were sending a signal right along the line; and, secondly, they all said ‘ow’ at the same time, and that meant that you were sending the signal very quickly, “explains Tom Standage, author of the Victorian Internet and technology editor at the Economist. Given a more humane detection system, this could be a way of signaling over long distances.

B

With wars in Europe and colonies beyond, such a signaling system was urgently needed. All sorts of electrical possibilities were proposed, some of them quite ridiculous. Two Englishmen, William Cooke and Charles Wheatstone came up with a system in which dials were made to point at different letters, but that involved five wires and would have been expensive to construct.

C

Much simpler was that of an American, Samuel Morse, whose system only required a single wire to send a code of dots and dashes. At first, it was imagined that only a few highly skilled encoders would be able to use it but it soon became clear that many people could become proficient in Morse code. A system of lines strung on telegraph poles began to spread in Europe and America.

D

The next problem was to cross the sea. Britain, as an island with an empire, led the way. Any such cable to be insulated and the first breakthrough came with the discovery that a rubber-like latex from a tropical tree on the Malay peninsula could do the trick. It was called gutta-percha. The first attempt at a cross channel cable came in 1850. With thin wire and thick installation, it floated and had to be weighed down with a lead pipe.
