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.

　　I went to summer camp with my classmates last summer. I never forget the
days.
　　Early in the morning, about 200 children from Grade. Seven came together
at the bus station from different schools. After saying goodbye to our parents, we
got on the buses. It took us more than two hours to arrive at the campground in
Qingdao.
　　We were laughing, shouting, jumping and running like birds when we got off
the buses. For us, It was our first time to be away from our parents .    
　　Swimming was my favorite class. It was about one o'clock in the afternoon.
It is the warmest time of a day and the best time to stay in cool water. With the
help of my swimming teacher, l could swim very well.
　　During the holiday, I learned many new things and made many new friends.
How happy I was!
