9.例: “留着、留着” “一只一只”,强调不停的留、不停的叠这些动作,表现诗人的执拗劲,由此寄托了诗人对母亲的思念之情。
10. “不灰心”不仅表现了作者对母亲思念的浓烈,而且表达了思念必将通过纸船传递给母亲的执著信念; “每天”既让人感受到叠纸船次数之多,又表现作者对母亲思念之持久和浓烈。(意思对即可)
11.①阅读,是一种多功能的活动,也是一种潜移默化的浸润活动。②阅读所能带来的脑力冲击,大得超乎想象。③阅读带来的大快乐,是任何其他的活动都难以相比的。
12.母亲对读书的痴迷影响了“我”,“我”对读书的痴迷影响了女儿;读书不但充盈了“我”一家三代人的心灵,而且还给予“我们”内心极大的快乐;读书让“我”一家三代人的生命得以浸润。
13.词语运用生动形象、准确到位,如“时时”表达出对读书的渴望是一种常态;“饥饿”形象地描绘出对书的强烈渴求。“如蚁附膻”“蚕吞桑叶”“蜂儿采蜜”运用比喻手法,把“我”读书时如饥似渴的情态刻画得生动形象、淋漓尽致。
14.回忆了“我”青少年时代一次买书的经历,表达了“我”对书的钟爱之情,喜欢的书买不到,有一种失落感,就像失去一个至爱的朋友一样,所以心中才有一种说不出的疼痛。
15. “我”觉得能通过自己的影响,让读书成为女儿生命中的组成部分,成为生存之需求,继而快乐其生命,润泽其生命,这便是“我”最大的成就。
16.答案略。(可举例说明阅读带给自己的影响,或谈某一部文学作品给自己带来的启发等。)

2 (1) n-1,n,n+1 (2) 2n-4,2n-2,2n
3 -2b 4 5 27 6 89
三
1、(1) 3(1-2ab2)-2(a2b-4ab2) (2) x-(3x-2)+(2x-3);
解:原式=3-6ab2-2a2b+8ab2 解:原式= x-3x+2+2x-3
=3-6ab2+8ab2-2a2b = x-3x+2x+2-3
=3+(-6ab2+8ab2)-2a2b = (x-3x+2x)+(2-3)
=3+2ab2-2a2b = -1
(3) 3a2-2(2a2+a)+2(a2-3a),其中a=-2;
解:原式=3a2-4a2-2a+2a2-6a
=3a2-4a2+2a2-2a-6a
=(3a2-4a2+2a2)+(-2a-6a)
= a2-8a
将a=-2代入得,原式=(-2)2-8×(-2)
= 4+16
= 20
