Test analysis: This test examines students' sentence sorting ability. Sentence sorting is determined according to the logical relationship between the sentence meanings before and after the sorting part and within the sorting sentence. The object of this topic is poetry, and the sentence before the sorting sentence is the topic, followed by the conclusion. When choosing an answer, you should determine the opening sentence according to four options. First of all, it should explain the long history of poetry; secondly, it should explain the history; fifthly, the "long years" should inherit the history. ⑤ After that, you can follow ① or ④. But according to the serial number of the last sentence provided by the option, only ③ can be used as the subject of "spiritual wealth" after B, so B is chosen.
