According to the passage, which of the following statement is true? ( )

参考解析：

是非题。C选项，由文中“European Union negotiators have refused to talk about post-Brexit ties until they judge that there is “sufficient progress” on the issues they consider a priority: the status of European Union citizens in Britain after it leaves, the border between Ireland and Northern Ireland(which is a part of the United Kingdom) and Britain’s financial commitments to the bloc.”可知此次演讲尚未涉及到一些的重要话题，欧盟国家对此表示不满，拒绝进一步谈判英国脱欧的相关事宜。C选项符合文意。A选项，文中“Brussels is insisting that Britain agree to the terms of the divorce before discussing future trade ties, while the British would like to do both simultaneously.”说明英国方面希望脱欧谈判与未来贸易关系问题讨论可以同时进行，A选项描述错误；B选项，特蕾莎·梅对于英国与欧盟关系尚未有一个详细的规划，譬如资金投入方面也仅有一个大致的承诺； D选项“Although Britain is scheduled to exit the European Union in 2019, there has been little progress in talks since March,”说明目前脱欧事宜进展不佳，D选项不符合文意。故本题正确答案选C。
