The histry f the Internet The Wrld Wide Web The Internet and the Web The future f the Internet
The Internet has been arund fr many years, but it was the inventin f the Wrld Wide Web that made it really useful t peple. Tgether, the Internet and the Wrld Wide Web have changed the wrld.
It was that...强调句型
The Internet was invented by the US gvernment in the 1960s, fr the army t use. In the 1970s, scientists and businesspeple als wanted t use the Internet t send and receive messages. Fr sme years, peple culd nly send very simple texts. They culd nt send phts r dcuments by the Internet.
That changed in 1991, when a British scientist named Tim Berners-Lee invented the Wrld Wide Web. The Wrld Wide Web allws peple t send varius types f files, such as texts, phts and vides by the Internet, s mre and mre peple started t use it in the 1990s.
Tday, the Web has hundreds f millins f users. It has changed the way peple live, wrk and play. Thrugh the Internet, email allws us t cmmunicate nearly instantly with peple thusands f miles away. Peple and businesses use e-cmmerce and nline shpping t buy and sell things acrss the wrld.
数百；成百上千；许许多多……
The Web als makes peple's lives easier because nw many things can be dne frm hme, twenty-fur hurs a day. The Web can help yu d research fr yur hmewrk, s that yu d nt need t g t the library. Yu can use Internet banking, instead f ging t the bank. And, f curse, peple just “surf the Web” when they want t relax.
Technlgy changes quickly, and it is hard t imagine what the future f the Internet and the Web will be. But it seems impssible t imagine life withut them.
Nw cmplete the chart.

Arund the w rld
E-bks Just as email has changed the way we write t each ther, e-bks are changing the way we read. We can easily dwnlad new e-bks frm the Internet. It is much easier and quicker t search fr passages nw, and we can als write ntes in an e-bk. What is mre, they save a lt f paper.
But e-bk readers are still mre expensive than paper bks, s nt all peple can affrd them. Hwever, with the rapid develpment f electrnic technlgy, reading e-bks will becme cheaper and cheaper. A lt f peple think there will be mre e-bks than paper bks in the near future.
