2.填字组词

不知所措

再接再厉

翻来覆去

无精打采

持之以恒

小心翼翼

焕然一新 3.解释词义

尴尬：处境困难，不好处理。须臾：一会儿，片刻。

4.示例：人们都爱莲花，爱她的亭亭玉立，爱她的香远益清。

人们都爱春天，爱她的勃勃生机，爱她的欣欣向荣； 人们都爱梅花，爱她的凌凌傲骨，爱她的冰清玉洁。人们都爱夏天，爱她的热情似火，爱她的枝繁叶茂。人们都爱冬天，爱她的千里冰封，爱她的银装素裹。仿写句式、用词（四字短语）恰当即可.5.①A.陆鹤（秃鹤）B.买鸽子。②杜小康 曾经那么优越的杜小康，在经历了坎坷的命运后，走出了孤独和困境，小小年纪就勇敢地挑起了生活的重担。他的经历令人心酸，又令人欣慰。我们也相信，假以时日，这个聪明而坚定的少年必成大器。所以桑校长如此看好杜小康。（人物形象把握正确，能结合选段内容分析。）6．律诗（五律）颔联

7.苍翠的树木在村边环绕，似把村庄环抱相拥；青翠的远山在村外横斜，与村庄依依相伴。句意理解正确；在此基础上加入合理的想象，能生动展现画面。8.这首诗表现了作者对田园生活的热爱之情和回归自然的情趣。9.丘 仲尼 春秋 儒 10．“说”通“悦”愉快，高兴.迷惑，这里指感到迷茫而无所适从

11.学习方法。只是学习而不思考就会迷惘；只是思考而不学习，那就有危险。这是孔子所提倡的学习方法。一味的读书，而不思考，只能被书本牵着鼻子走，就会被书本所拖累，就会被书本表象的迷惑而不得其解；而只是一味的埋头苦思，不进行一定的书本知识的学习积累，进而对知识进行研究推敲，也只能是流于空想，问题仍然不会得到解决，也就会产生更多的疑惑而更加危险。只有把学习和思考结合起来，才能学到有用的真知。比如说，你在背数学定义或公式时，只是死记硬背，并不加以理解、思考，也许你一天两天记得，时间久了就会因不明白其含义而容易忘记了。能结合自己实际谈出学思必须结合即可。

12.哪有整天拿着烤肉而不知道它味道的？...13.善有善报。意思对即可。

课内篇

（一）1.①“看花”是全文围绕的中心事件。②“看花”是母爱的集中体现。③“看花”是“我”新生活的象征，是母亲愿望的达成。

2.①母亲十分体谅儿子的苦衷。②母亲周到细心，尽可能不去惊扰儿子。③母亲的心里更难受。

3.①母亲是一个非常热爱生活的人。②母亲为儿子放弃了对生活的享受。4.①“央求”反映出母亲既盼望儿子早日摆脱阴影，又怕自己支撑不到那一天的复杂心理，若换成“期待”则不能突出母亲忍着巨大病痛仍一心为儿子着想这一特点。②从词义看，“央求”含有最低要求的意思，“期待”则指较高要求。

5.不能去掉。①“秋天”是背景和“引子，文中写景、叙事、记人，都与”秋天“有关。②”秋天“是”我“不幸遭遇、暗淡心情的写照，具有象征性。③”秋天“也是”我“走出低谷、乐观生活的象征。课内篇

4．含义：内心纯净、淳朴、天真的学生。作用：老师的赞扬是对 “我”的支持和安慰，表现老师的慈爱和教育的艺术性。5.C 抒情 课外篇

1.“我”怕父亲给我丢脸，而让父亲在拐角处等我；张小凡懂得关心父亲，维护父亲的尊严让父亲在拐角处等她。

2.动作 神态描写 坚强冷静，成熟倔强 3.为自己的自私而难过；为误解张小凡而难过；为不关心父亲不懂得维护父亲的尊严而难过；为自己没有张小凡懂事而难过。

4.父爱如山，深沉而厚重。所有的父亲似乎都不善于说“爱”，不懂得如何去直接表达“爱”。但都会在背后默默的奉献着一切，以致于我们对父爱不理解，甚至忽略了父爱。父爱总是通过一种具体的方式表露出来，如父亲会在炎热的夏天为我买5元的冷饮，而自己却只喝白开水。

高积云是成群的扁球状的云块，排列很匀称，云块间露出碧蓝的天幕，远远望去，就像草原上雪白的羊群。6.“常”、“一般”在句子里都有限制作用，表明经常、一般这样，排除了特殊情况，体现了说明文语言的严谨和准确。

《皇帝的新装》

1.”弄“字用得好。一个”弄“字，与上文的”装“字、下文的”好像“、”系"相互照应，生动形象地描绘了骗子装模作样的形象，从而对表现皇帝的昏庸愚蠢起到有力的衬托作用。(三个要点，能说出第二个要点就可以肯定)2．皇上在镜子面前转身扭腰，是装出欣赏自己的新衣服的样子，以便掩饰自己看不到新装的事实。这反映了他虚伪、愚蠢而又荒唐的特点。3．人们齐声称赞皇帝那并不存在的新装，是因为谁也也不愿意让人知道自己什么也看不见，谁也不愿显出自己不称职，或是太愚蠢。

4．小孩子天真单纯，无私无欲，所以讲真话。这告诉我们，只有保持天真单纯的童心，才能做到无私无畏，敢于讲真话。

（三）弱种子也要发芽

1．⑴挑种种地 ⑵种下瘪种

2．⑴冷落（“漠视”或“抛弃”）。⑵让城里人的儿子看到他对瘪种子有着很高期望，也是农民被触动后的行为表现。

3．农民是一个宽厚友善、知错就改、有责任心的父亲。

4．示例一：我觉得是农民，因为是农民花去了所有的积蓄为他安最好的假肢，让他发芽、开花、结果，给了他成长的力量。示例二：我觉得是城里人父子，因为是他们促使农民改变了想法，才让他有了发芽、开花、结果的希望。

5．用“弱种子”喻指存在某种缺陷的生命，小说以“弱种子也要发芽”为题告诉读者即使有缺陷的生命也有成长的权利，不能被剥夺；也喻劝人们要呵护“弱种子”，使其发芽、开花、结果。

Internet is educational.Many people think children should be allowed to surf the Internet as they wish.In this way, they can look through different subjects on different kinds of websites according to their own internets.But in my opinion, children should always be watched while surfing the internet.Many websites have information and pictures that children should not see.There are many things that children don’t understand.All of these may have some bad influence on children’s development.Also, it is dangerous to let children use chat rooms by themselves.Many parents tell their children not to talk to strangers on the street, so they should be careful of whom their children talk to on the Internet, too.What’ more, sitting in the front of a computer for a long time isn’t good for children’s eyes, so parents should monitor the time that children spend on the Internet.In a word, children should be kept away anything that could be bad for them.I strongly believe that it is necessary for parents to watch their children when they use Internet.1.Is the Internet educational all the time? 2.What do the parents tell children to do when they meet strangers on the street? 3.Why shouldn’t children sit in front of a computer for a long time? 4.Who can help children stay away from the bad influence on the Internet? 5.What does the writer want to tell us in the passage? 五． 短文填空（首字母给出）
