2026年一遍过八年级英语上册外研版第90页答案
[2025 上海金山区二模]In the early part of human history, communication over long distances was slow and unreliable(不可靠的). This article can help you find out how advancements in communications have transformed the way people communicate and how businesses are run.
Smoke signals and carrier pigeons
From historical dramas, you might have seen methods of communication such as messages relayed through smoke signals or the pigeon post.
Postal letters
With the rise of maritime(海上的) shipping, postal letters were carried between two main areas of land in the world. However, these letters often took months to arrive and might be lost due to disasters at sea.
Telegraphs and telephones
The telegraph was developed in the 1830s to transmit (传送) electrical signals over a wire installed between telegraph stations. Later, scientists invented receivers that were able to turn electricity into sound. This led to the development of telephones in the 1870s which allowed the human voice to be transmitted over wires.

Smartphones
Since the 2000s, telephones and mobile phones have developed rapidly, enabling people to keep their attention on a range of functions beyond making calls. With key developments in wireless networks, mobile processors and camera technology, people are now able to communicate with others across different time zones and over various distances via instant video calls using their smartphones.
