D解析试题分析：句意:茶道尽管在日本很流行，据说它是起源于古代的中国。这里是sth be said to do,这里is said用的是现在时，originate发生在is said之前，所以用不定式的完成时，并且tea ceremony与originate之间是主动关系，故选D。考点：考查非谓语动词的用法。
点评：本题难度适中。非谓语动词是高中阶段的难点，需要考生能够理解该题的语言环境，进而作出正确的判断。会判断非谓语动词与它的逻辑主语之间是什么关系及其谓语动词及非谓语动词的动作发生的先后关系，需要考生掌握非谓语动词的不同形式的用法区别等。即学即练: There’s a man at the reception desk who seems very angry and I think he means __________ trouble.A. making B. to makeC. to have made D. having made解析：B。mean＋to do意为“打算/想要做……”;mean doing意为“意思是……；意味着……”。由句意可知应选B。
