【简答题】在容积为1 L的密闭容器中,进行如下反应: A(g)+2B(g) C(g)+D(g),在不同温度下,D的物质的量n(D)和时间t的关系如图。 请回答下列问题: (1)700℃时,0~5min内,以B表示的平均反应速率为_______。 (2)能判断反应达到化学平衡状态的依据是__________。 A.容器中压强不变      B.混合气体中c(A)不变 C.v 正 (B)=2v 逆 (D)   ...
【单选题】对《我愿意是急流》赏析不正确的一项是( )
A.
诗篇标题是“我愿意是急流” ,然而它却未凝聚全诗的主题;全诗的主题应该是歌颂奉献精神。
B.
诗篇的表现方法主要是比喻。诗人选择了急流、小河、小鱼、荒林、小鸟、废墟、常春藤、草屋、炉子、火焰、云朵、夕阳„„一系列比喻,多角度刻画了“我”的高大形象。
C.
诗中的第一人称“我”,可以说是诗人自己的化身。文学作品中用第一人称来写,易给人一种真实感,例如《一件小事》《记念刘和珍君》中的我,都是鲁迅先生本人
D.
诗篇形式优美。全诗 5 段,每段 8 句,整齐划一;句式简短,节奏感强;译文注重韵脚,使得旋律悠扬,铿锵悦耳。
