白杨礼赞的礼赞是什么意思

《白杨礼赞》中“礼赞”的意思就是崇敬而赞美,以“赞美白杨树的不平凡”作为抒情线索,把白杨树生长环境的不平凡,外部形态的不平凡和内在气质的不平凡构成一体。
《白杨礼赞》是茅盾1941年在重庆写的。茅盾耳闻目睹在党领导下抗日根据地人民的沸腾生活,体验到抗日军民质朴、刚强、团结一致、艰苦奋斗的精神,受到极大的鼓舞,对民族解放的光明前途充满信心,满怀激情。这篇文章采用象征手法,通过对白杨树不平凡的形象的赞美,歌颂了中国共产党领导下的抗日军民和整个中华民族的紧密团结、力求上进、坚强不屈的革命精神和斗争意志。

天门中断楚江开的开字妙在何处

“天门中断楚江开”中“开”字妙在以下三个方面:
1、体现出楚江的霸气和恢弘。
2、体现出楚江的雄浑和刚强。
3、形象地描绘了天门山被楚江隔开的景象。
出自《望天门山》:“天门中断楚江开,碧水东流至此回。两岸青山相对出,孤帆一片日边来。”
译文:
天门山从中间断裂是楚江把它冲开,碧水向东浩然奔流到这里折回。
两岸高耸的青山隔着长江相峙而立,江面上一叶孤舟像从日边驶来。
《望天门山》是唐代大诗人李白于开元十三年(725年)赴江东途中行至天门山时所创作的一首七绝。此诗描写了诗人舟行江中顺流而下远望天门山的情景:前两句用铺叙的方法,描写天门山的雄奇壮观和江水浩荡奔流的气势;后两句描绘出从两岸青山夹缝中望过去的远景,显示了一种动态美。全诗通过对天门山景象的描述,赞美了大自然的神奇壮丽,表达了作者初出巴蜀时乐观豪迈的感情,展示了作者自由洒脱、无拘无束的精神风貌。作品意境开阔,气象雄伟,动静虚实,相映成趣,并能化静为动,化动为静,表现出一种新鲜的意趣。

什么叫沟通

沟通,汉语词语,拼音为gōu tōng,意思是使双方互相通连,也指人与人之间、人与群体之间思想与感情的传递和反馈的过程,以求思想达成一致和感情的通畅。
没有出处。
近义词:交流、商议、商量。
反义词:堵塞、封闭。
用法:作动词;作谓语;中性词;可用于人,也可用于事物。
例句:有效的沟通并不只是说话就行的,应该是言简意赅,也就是用最少的话把意思表达清楚。
造句:
1、虽然同是中国人,各地区的方言却千差万别,很难互相沟通。必须普及普通话,达到用语言交流的目的。
2、沟通是春天的暖流,充满渴望;沟通是夏天的骄阳,炽热无比;沟通是秋天的大雁,盼望南飞;沟通是冬天的火炉,温暖人间。
3、如果沟通是漆黑的深夜,那么语言便引着你走向皓月当空,繁星满天;如果沟通是通向一望无际的沙漠,那么语言是引领你走向鸟语花香的绿洲;如果沟通是浩瀚无边的大海,那么语言便引领你走向乘风破浪的境界。

风雪夜归人是什么意思

“风雪夜归人”意思是风雪夜回宿的家人回来了。出自唐代诗人刘长卿的《逢雪宿芙蓉山主人》,这首诗首句写日暮山远,次句写投宿的人家,后两句写风雪交加、犬吠人归的情景。全诗语言朴实浅显,写景如画,叙事虽然简朴,含意十分深刻。
原文:
日暮苍山远,天寒白屋贫。
柴门闻犬吠,风雪夜归人。
译文:
暮色降山苍茫愈觉路途远,天寒白屋显得更贫困。
柴门外忽传来犬吠声声,风雪夜回宿的家人回来了。
这首诗用极其凝炼的诗笔,描画出一幅以旅客暮夜投宿、山家风雪人归为素材的寒山夜宿图。诗是按时间顺序写下来的。首句写旅客薄暮在山路上行进时所感,次句写到达投宿人家时所见,后两句写入夜后在投宿人家所闻。每句诗都构成一个独立的画面,而又彼此连属。诗中有画,画外见情。
