D解析试题分析：第一空sing与songs之间是被动关系，这是一个过去分词短语作定语，故排除BC；inform sb of 告知某人某事，这里parents与inform之间是被动关系，故选D。考点：考查非谓语动词的用法。
点评：本题难度适中。不容置疑，高考将继续加强对非谓语动词的考查，试题的特征将继续呈现出“情景化”和“设问角度的多样化”的趋势，但试题的难度将会有所控制。即学即练：I wasn't______of the decision until it was too late.A. exchanged B. broadcasted C. approve D. informed 解析：D。句意：等到我得知这项决定时,已经太迟了。
