27、语句,归纳其特点,尝试从表达目的、听众的感受角度品评其表达效果。阅读时,还要注意思考,理解这篇文章的针对性和现实意义。2.只有懂得舍与得，才不会被利禄牵扯而过度奔波劳累；一个人只要能够自得其乐，即使有所失也不会为此不快乐；一个人只要拥有高深的道德修养，即使没有官位也能内心平静轻松。3.文本中不断提到“大自然”，在充满了诗情画意的大自然面前，在可爱温顺的小动物面前，素芭没有任何交流的障碍，她甚至能比常人更为轻易地表达自己。4.作者用了几乎两章的篇幅，把素芭放置到比社会环境温暖得多的自然环境中，在这里，素芭不仅是美好的，还有着无言的快乐。侧面的烘托让素芭的形象更为动人。5.反面的衬托同样是塑造素芭

28、形象的一个手段。素芭身边的人们可以用话语交流，他们是一群极为普通的劳作者，包括帕勒达帕，可是他们对素芭的表现却显得极为冷漠和麻木。6.素芭在他们身上看不到关心，找不到温暖。在小说的第五章，父母打算用欺骗的手段把素芭嫁到加尔各答，而且“没有作任何安慰”。7.整个事件的过程中，素芭只有独自流泪伤心，得不到任何关心，唯一的所谓的好友帕勒达帕只是专心致志地钓鱼，丝毫没有离愁别绪，反倒是漫不经心地证实了这个噩耗，给了素芭更大的打击。8.诗人运用浪漫主义的表现手法，热情地赞颂了云雀在诗人的笔下，云雀是欢乐、光明、美丽的象征。作者运用比喻、对比等修辞手法，对云雀加以描绘。9.在中国特色社会主义新时代，只有坚持和加强党的全面领导，才能真正落实以人民为中心的发展思想，建设现代化经济体系，健全人民当家作主的制度体系，推动社会主义文化繁荣兴盛，保障和改善民生，加强和创新社会治理，加快生态文明体制改革，正确认识和应对复杂的国际局势
