2020-2021历年中考语文易错题汇编-诗歌鉴赏练习题附答案解析
一、中考语文诗歌鉴赏 1．下列对《十五从军征》一诗的赏析，不恰当 ．．．的一项是（） 十五从军征 十五从军征，八十始得归，道逢乡里人：“家中有阿谁？” “遥看是君家，松柏冢累累。”兔从狗窦入，雉从梁上飞。 中庭生旅谷，井上生旅葵。春谷持作饭，采葵持作羹。 羹饭一时熟，不知饴阿谁！出门东向看，泪落沾我衣。 A.“八十始得归”中“始”字，巧妙地传达出主人公从军多年思念家乡，盼望与亲人团聚的迫切心情，给全诗笼罩了一层凄凉悲伤的感情色彩。 B.“兔从狗窦入，雉从梁上飞。中庭生旅谷，井上生旅葵。”这四句以乐景写哀情，写老兵出征归来，看见故居充满生机和活力的情形。 C.“出门东向看，泪落沾我衣”这两句细节描写，将老兵举目无亲、孤身一人、寂寞难耐的形象刻画得栩栩如生，读后令人心酸。 D.本诗是一首叙事诗，采用第一人称，借一个老兵从军多年回家后的所见所闻，揭露了封建社会不合理的兵役制度对普通百姓带来的苦难。 【答案】B 【解析】 【详解】 试题分析：诗句“兔从狗窦入，雉从梁上飞。中庭生旅谷，井上生旅葵”由遥看到近见，满眼更加荒凉凄楚的景象。作者没说室空无人，而是抓住野兔见人钻进家畜窝中自以为得所，野鸡惊飞落到屋内梁上自以为安的情景，写出了人去屋空，人亡园荒的萧条衰败的景象。所以B项对这四句话“以乐景写哀情，写老兵出征归来，看见故居充满生机和活力的情形”的理解是错误的。故答案为B。 2．阅读诗歌，回答问题。 夏意 （宋）苏舜钦 别院深深夏席清，石榴开遍透帘明。 树荫满地日当午，梦觉流莺时一声。 （1）本诗一反盛夏炎炎的立意，表现了怎样的“夏意”？ （2）请对“梦觉流莺时一声”一句进行赏析。 【答案】（1）表现了凉爽、清幽、宁谧的“夏意”。 （2）“流莺时一声”衬托前三句所营造的宁谧幽静之境，以有声衬无声；也以动衬静，以莺之流飞，让整个画面陡然灵动丰满起来。 【解析】 【详解】 （1）考查对诗歌内容的理解。诗中虽写炎热盛夏，却句句显清凉静谧、清幽朦胧的气氛。第一句写午睡的场所，“深深”说明别院深幽寂静，因为寂静，而感到了“清”，体现出

(2)得病死去了,(弟弟)把他的灵柩送回了应山。 4．写了连处士照顾父亲而不仕、资助乡亲度灾年、原谅窃牛者等事情。从中看出连处士是一个孝以侍亲、乐善好施、宽以待人。 【解析】 1．理解词语的含义时要注意文言词语的特殊用法，如通假字、词类活用、一词多义和古今异义，能结合具体语境来准确辨析即可。涉及的词语都是常见的文言实词。解答时要联系 一、旋转真题与模拟题分类汇编（难题易错题） 1．(1)发现：如图1，点A为线段BC外一动点，且BC＝a，AB＝b．填空： 当点A位于时，线段AC的长取得最大值，且最大值为(用含a，b的式子表示) (2)应用：点A为线段BC外一动点，且BC＝4，AB＝1，如图2所示，分别以AB，AC为边，作等边三角形ABD和等边三角形ACE，连接CD，BE． ①请找出图中与BE相等的线段，并说明理由；②直接写出线段BE长的最大值． (3)拓展：如图3，在平面直角坐标系中，点A的坐标为(2，0)，点B的坐标为(6，0)，点P 为线段AB外一动点，且PA＝2，PM＝PB，∠BPM＝90°，请直接写出线段AM长的最大值及此时点P的坐标． 【答案】(1)CB的延长线上， a+b；(2)①CD＝BE，理由见解析；②BE长的最大值为5；(3)满足条件的点P坐标(222)或(222)，AM的最大值为2+4． 【解析】 【分析】 （1）根据点A位于CB的延长线上时，线段AC的长取得最大值，即可得到结论；（2） ①根据已知条件易证△CAD≌△EAB，根据全等三角形的性质即可得CD＝BE；②由于线段BE长的最大值＝线段CD的最大值，根据（1）中的结论即可得到结果；（3）连接BM，将△APM绕着点P顺时针旋转90°得到△PBN，连接AN，得到△APN是等腰直角三角形，根据全等三角形的性质得到PN＝PA＝2，BN＝AM，根据当N在线段BA的延长线时，线段BN取得最大值，即可得到最大值为2+4；如图2，过P作PE⊥x轴于E，根据等腰直角三角形的性质即可求得点P的坐标．如图3中，根据对称性可知当点P在第四象限时也满足条件，由此求得符合条件的点P另一个的坐标． 【详解】 (1)∵点A为线段BC外一动点，且BC＝a，AB＝b， ∴当点A位于CB的延长线上时，线段AC的长取得最大值，且最大值为BC+AB＝a+b， 故答案为CB的延长线上，a+b； (2)①CD＝BE， 理由：∵△ABD与△ACE是等边三角形， ∴AD＝AB，AC＝AE，∠BAD＝∠CAE＝60°， ∴∠BAD+∠BAC＝∠CAE+∠BAC， 即∠CAD＝∠EAB， 中考英语单项选择易错题精选 1.What do you think ______solve the problem ?
