Today almost everyone knows computers and the Internet.If I ask you what the most important in your
life is，maybe you will say“computers and the Internet”．
The first computer was made in 1946.It was very big but it worked very slowly.Today computers are
getting smaller and smaller.But they work faster and faster.What can computers do ？A writer has
said，“People can't live without computers today.”
The Internet came a little later than computers.It is about twenty－five years later than computers.But
now it can be found almost everywhere.We can use it to read books，write letters，go shopping，play
games or make friends.
Many students like the Internet very much.They often go into the Internet as soon as they are
free.They make friends on the Internet and maybe they have never seen these friends.They don't know their
real names，ages，and even sex.They are so interested in making“unreal friends”that they can't put their
heart into study.Many of them can't catch up with others on many subjects because of that.
We can use computers and the Internet to learn
more about the world.But at the same time，we should remember that not all the things can be done
by computers and the Internet.
5．The Internet cannot be used for ________．
A．studying B．shopping
C．thinking D．playing
6．The Internet was born in about ________．
