C.
翻译：我不知道你是否听说了,我9月份要去美国学习
高中英语语法题,高三经常见到.主要考察happen to和不定式的主动表被动.习惯选A（误认为you和hear的关系是被听）.在不定式中,有一些词是用主动形式表示被动,比如感官动词（一感、二听、三让、四看）等.所以这个听的hear 属于二听里面的一个（另一个是listen to).
例子：He gave me a good video to see（me 和 see 的关系也是被动,但用to see主动形式）
PS：你可以搜一下不定式的主动表被动,有介绍的.

happen to do sth , 碰巧做某事。所以很多同学容易直接选C。但在本题中根据题意“我准备九月份去美国”这件事发生在前。从语法上讲，用完成时态，表示更好，因为不是我说的同时你碰巧正在做某事，而是早已经听说。 所以选D

C

非谓语动词作状语，并且表被动 选D
