单选题
【B1】
【正确答案】
C
【答案解析】解析：考查动词辨析。文中提到的电话银行、传真等是对commercial offerings的举例说明，这些例子显然与电子商务概念中提到的all commercial…over the Internet相符，由此可知，二者在概念上没区别，故答案为C．differ“有区别”。distract“转移”；descend“下来，下降”；derive“起源”，均不符合题意。
【答案解析】解析：考查动词辨析。allow sb．to do sth．为固定搭配，意为“允许某人做某事”，代入文中，意为“最后．电子商务是允许通过电子的方式来发送付款信息的，而不是通过邮寄支票这类纸质的支付证明”，符合文意。故答案为D．allows。本文后面提到的allowed one to order products对本题有提示作用。其他三项均不符合题意。
