关于do you perfer to pay by credit or cash?why?的话 一小段就行了,口语考试急

I prefer to pay by credit card. First, it's more convenient to pay by credit card than in cash. You don't want to carry 10,000 yuan, do you? Second, it very safe to use credit cards, because only you can use them, but cash can cause a lot of problems, say danger. Third, as you know, cash may be dirty. That may cause illnesses. So I'd like to use credit cards.
