阅读下面一首诗歌,回答(1)~(4)题。

登高

杜甫

风急天高猿啸哀,渚清沙白乌飞回。

无边落木萧萧下,不尽长江滚滚来。

万里悲秋常作客,百年多病独登台。

艰难苦恨繁霜鬓,潦倒新停浊酒杯。

(1)对下列诗句解说不恰当的一项是(     )

A.诗中写登高所见的秋江景色,抒发了长年漂泊、老病孤愁的感情。

B.本诗第一、二句写俯仰所见所闻,一连出现了六个特写镜头,渲染了秋江景物的特点。

C.有人认为本诗第三、四句“无边”“不尽”两词多余,其实正是有了这两个词,诗的意境才显得更广阔深远,气象万千。

D.诗的最后两句,写外界环境带给作者的艰难苦恨和自身随年龄增长而白了的头发,使得自己连喝酒的兴致都没有了。

(2)对这首诗的赏析不恰当的一项是(     )

A.本诗情景交融,气象宏伟,悲凉的景物融合了诗人心上的悲凉。

B.诗中“萧萧下”绘落叶之声,“滚滚来”状江浪之势,正衬托诗人宽阔的胸怀。

D.本诗是一首七律,中间有两联对偶,韵律和谐,每句都是四个节拍,如“风急/天高/猿/啸哀”。

A.首句的“风”“天”“猿啸”分别与下句的“渚”“沙”“鸟飞”对仗,读来富有节奏。

B.颔联的对仗十分精工,“无边”“不尽”使“萧萧”“滚滚”更加形象化,沉郁悲凉的对句出神入化。

C.颈联的“万里”“百年”和上联的“无边”“不尽”还有相互呼应的作用。

D.颈联表现感情,“万里”“百年”分别从纵(时间)、横(空间)两方面着笔。
