【正确答案】 A

【答案解析】考查动词，此处的主语是e-commerce，宾语是payment information，再结合这一段中连续的三个相同的句式，前两个均使用了arranges for这个表达，于是此处也应该找类似的用词，于是选择allows为最佳，其它的选项：appeal(吸引)，advocate(拥护，鼓吹)，admit(允许)。

【正确答案】 B

【答案解析】考查介词，用来表示时间关系，这个段首句的问题，以本句来看是没有线索的，必须依靠对本段的整体理解。在读完这段的内容后，可以发现，这段提到了1993年时的网络状况，以及在1997年之后，网络才快速发展的，那本题也就可以做出选择了，也就是说在1993年之后的十年，电子商务才成为主流的。

【正确答案】 A

【答案解析】考查形容词，形容词在这里修饰名词novelty(新奇事物)，这里的几个选项分别为：insignificant(不重要的)，optional(可选的)，invalid(无效的)，occasional(偶然的)，由此可知，能够修饰新奇事物的只有insignificant。

【正确答案】 B

【答案解析】考查名词，名词是被形容词来修饰的，结合之前的few，说的是几乎没有，后面又讲到允许订购，说明这里应该是指企业，或者说公司，于是可知最佳选项为corporations(企业)。其他选项的意思分别为：communities(集体，社区)，compounds(混合物，合成品)，corps(军，军团)。
