Could anyone help me to answer these questions? Thank you very much!!!! :-)
1. Extract: "Computers are now essential in many areas of life- modern banking, retail, and information exchange among others."
Are there any word which is more appropriate than "areas of life" or "areas of life" sounds natural and there is no need to replace it with another phrase?
2. Extract: "some subject may be better taught using computers"
Why they use "using computers"? What is the subject of "using computers"? Could you help me to write the full sentence with the subject of "using computers"?
