参考答案
一、(1)11 (2)12 (3)13 (4)14 (5)14 (6)15 (7)12 (8)15 (9)16 (10)16 语文课本中的文章都是精选的比较优秀的文章，还有不少名家名篇。
如果有选择循序渐进地让学生背诵一些优秀篇目、精彩段落，对提高学生的水平会大有裨益。
现在，不少语文教师在分析课文时，把文章解体的支离破碎，总在文章的技巧方面下功夫。
结果教师费劲，学生头疼。
分析完之后，学生收效甚微，没过几天便忘的一干二净。
造成这种事倍功半的尴尬局面的关键就是对文章读的不熟。
常言道“书读百遍，其义自见”，如果有目的、有计划地引导学生反复阅读课文，或细读、默读、跳读，或听读、范读、轮读、分角色朗读，学生便可以在读中自然领悟文章的思想内容和写作技巧，可以在读中自然加强语感，增强语言的感受力。
久而久之，这种思想内容、写作技巧和语感就会自然渗透到学生的语言意识之中，就会在写作中自觉不自觉地加以运用、创造和发展。
二、(1)6 (2)7 (3)8 (4)8 (5)4 (6)5 (7)3 (8)9 (9)10 (10)8

教师范读的是阅读教学中不可缺少的部分，我常采用范读，让幼儿学习、模仿。
如领读，我读一句，让幼儿读一句，边读边记；第二通读，我大声读，我大声读，幼儿小声读，边学边仿；第三赏读，我借用录好配朗读磁带，一边放录音，一边幼儿反复倾听，在反复倾听中体验、品味。
