A sign is another kind of language. Here are some of them that you see on the

sign when we are getting near a town.          
　　Number Two is a sign that we’re near a crossing. We must drive carefully.
Number Three is a sign that there is a bend (拐弯) in the road. Again, we must

　　We are all busy talking about and using the Internet,but how many of us
know the history of the Internet?Many people are surprised when they find that
the Internet was set up in the 1960s.At that time,computer networks didn't work
well.If one computer in the network broke down, then the whole network stopped.
So a new network system had to be set up.It should be good enough to be used by
many different computers.If part of the network was not working,information
could be sent through another part.In this way computer network system would
keep on working all the time,I'm daydaytest Placeholder
　　At first the Internet was only used by the government, but in the early 1970s,
universities, hospitals and banks were allowed to use it, too. However, computers
were still very expensive and the Internet was difficult to use.By the start of the
1990s,computers became cheaper and easier to use.Scientist had also developed
software (软件) that made "surfing" the Internet more convenient (方便的).
　　Today it is easy to get on-line and millions of people use the Internet every
day. Sending e-mail is more and more popular among people.
　　The Internet has now become one of the most important parts of people's
life.
