【单选题】《征人怨》柳中庸 岁岁金河复玉关,朝朝马策与刀环。 三春白雪归青冢,万里黄河绕黑山。 下列对诗歌理解有错的一项是( )
A.
这是一首是边塞诗，全诗四句，一句一景，表面上似乎不相连属，实际上却统一于“征人”的形象，都围绕着题目中的“怨”字铺开。
B.
“岁岁金河复玉关，朝朝马策与刀环”，这两句“岁岁”和“朝朝”相对，强调了战争的频繁和生活的枯燥。又加以“复”和“与”字，使人感觉这种单调的生活无尽无穷，其中自然透出了怨情。
C.
“三春白雪归青冢，万里黄河绕黑山”，这两句写三句写边塞之景，暮春塞外无春色，唯有白雪向青冢；滔滔黄河，绕过沉沉黑山，复又奔腾向前。这两句写景与诗题没有任何关联。
D.
此诗四句不着一个“怨”字，只是客观地记录征人岁岁朝朝征战的生活情况，描绘边地荒凉寒苦的景象，而征人深深的怨情已寓于其中，表现了诗人对统治者穷兵黩武的谴责之意。
