第一篇：关于计算机的英语作文

As the economy develop,that every desk in the office has a

computer has not been a fresh thing.Nowdays,more and more

officers use the computers.It seems that the computers play an

important part of it.Firstly,people use computer programmes

such as word,excel to type the documents and store the

datas.Secondly,it helps us a lot to communicate with others.With

the help of the net you can get many useful imformations,you

can make friends with different people who are known or

unkown,you can ask the help or question the answer.Because of

it,we can get in touch with people in a matter of second even

they are thousands distances away from us!What's more,we can

have a meeting togeter by using the computer.But what I have to

mention is that we can't rely the computers too much.It

sometimes also do harm to us.For example,many workers may be

addicted to the computers during their work,which as result that

they are not work hard enough.In addition,the computers also

have radiation that is not good to our health In my opinion,i am

supposed that everyone should use computer proper, Only doing

so can we benefit from the computers.
