网考网解析：
[解析] 副词辨义。上句提到，连接到NSF网络上的大多数大学都拥有校园内部的计算机网络。本句承接上句的意思，NSF网络就成为连接成千上万个其他网络的网络。所以使用表示承接关系的副词then符合句意，D项为本题正确答案。moreover意为“而且，此外”，表示递进关系；however意为“然而，可是”，表示转折关系；likewise意为“同样地”，表示类比关系。这三个副词均不能表示承接关系，所以均可以排除。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
