大师
①他是个普通的石匠，那天，接到一桩大买卖。邻村的财主要用汉白玉为去世的母亲 雕座真人像，放在园子里，天天看着。
②第一次听到消息时，他不敢相信这样的好运会落在自己身上。一个石匠能雕刻玉石，应该说身价上了一个台阶。他知道这是一次机会，如果真的完成了这座人像，那么他就可以
教学课件 在石像上刻上自己的名字。那时，他就是石匠行当里数一数二的人物了，再也不会雕那些石碑石人石马，摆在自家门前，等人来收购，然后送到墓地，过着清贫的日子。因为那时，他应该是位大师了。
③他认真地做着准备工作。先将所有的工具磨了一遍，然后将自己关了三天三夜，只看财主母亲的一幅画像，那画像似乎是女人年轻时候的，看上去很漂亮。石匠将那女人的相貌记在了心里。
④当他做好一切准备工作，来到财主家，第一眼看见那块汉白玉的时候，就已经按人体的比例位置，将那块漂亮的汉白玉给划分了，包括他的名字刻在哪里。他给自己的名字找了三个地方，一是在人像裙子的下摆处，二是在人像的袖口处，还有就是在人像的背后。⑤石匠构思好了便开始干活。一个月过去，人像完成了。财主来看的时候叫了起来：“你这刻的不是我母亲！”石匠找出财主母亲的画像，对比着看了起来。看着看着也觉出不像，但他没说，只是拿着画像给财主看。可财主却不看画像，冲着石匠说：“你现在雕的只是像我母亲，而不是我母亲。如果你只能做成跟这幅画一样，那我要你来雕什么？我有这幅画就行了。”说着，财主指着人像的袖口处说：“这是什么？你的名字？这画上有吗？我跟你说，你要雕得不好，这汉白玉的钱你出！”说完扬长而去。
⑥石匠傻了眼，他没想到会是这样的结局。没赚到钱还要赔钱，要是传出去，在这个行当里就没法混了。石匠坐在人像前，目光呆呆地看着他亲手雕出来的人像，不知道怎么办才好。时间一点点过去了，月光洒落在人像上，映衬出汉白玉的洁白。石匠透过月光看见汉白玉发散出一片金光，在那金光里他看见了离世多年的母亲，正满含愁苦却不失慈祥地看着他。石匠，多年没看见母亲了，他想起母亲带给他的温暖，以及在他年少时母亲给他的关爱。这个时候，他突然想扑进母亲的怀里，再一次感受母亲给他的爱。他扑了上去，摸到的却是冰冷的石头，石匠的眼泪一下子流了出来。
⑦石匠又在雕刻那座人像了，一个月过去了，没有完工。两个月过去了，还是没有完工。财主派人来看了几次，回去报告说还没有完工。整整十个月，石匠每天对着汉白玉慢慢地雕刻着，汉白玉是越来越鲜活，而石匠却是日渐消瘦。
⑧十个月后，财主再次看见人像的时候，一下子跪倒在人像前，失声痛哭起来。跟来的家丁们也一下子肃然起敬，眼前的人像就是他们当年的老夫人。
⑨一个管家模样的人绕着人像转了几圈后，轻轻地走到石匠面前说：“你还没刻上你的名字。”
⑩石匠看了看天空，淡淡地说：“这么洁白的人像上为什么 要刻我的名字？”说完，他停了一会儿，似乎在思考什么，然后对那个人说：“我好像忘了我的名字，你能告诉我吗？”
教学课件 11那人一下子弯下了腰，轻声地说：“你的名字叫大师。”（选自《天池小小说》，有删改）
23．阅读文章，根据提示填写表格。（3分）
故事情节：接了桩大买卖 → → 想起母亲，感受母爱→ 成为大师 ↓ ↓ ↓ ↓
心理状态： → 沮丧 → 感动 → 24．联系上下文，说说第④段画线句子的作用。（4分）
25．下面表述有误的一项是（）（3分）
A．第②段中“他知道这是一次机会”，石匠认为这是一次提高自己雕刻技艺的机会。B．第⑤段中“你现在雕的只是像我母亲，而不是我母亲”一句，说明石匠雕出的人像只是形似，而缺少神韵。
C．第⑧段写财主“一下子跪倒在人像前，失声痛苦起来”，“一下子”表现出财主看到人像立刻被打动了，从侧面表现了石匠的技艺达到了出神入化的境地。
D． 文章最后一段，借别人之口说出“你的名字就叫大师”，既起到点题的作用，同时又收束全文。
26．如何才能成为大师？联系全文，谈谈你的感悟。（4分）

散步 龙应台
①回屏东看母亲之前，家萱过边境来访。细致的她照例带了礼物。一个盒子上写着“极品 燕窝”，我打开看一下，黑溜溜的一片，看不懂。只认得盛在瓷碗里头加了冰糖的白糊糊又香又甜的燕窝。不过，家萱当然是送给母亲吃的，我不需操心。
②她又拿出一个圆筒，像是藏画的。一卷纸拿出来，然后一张一张摊开，她说：“我印得多了，想想也许你妈可以用。”
③海报大小的白纸，印着体积很大、油墨很浓的毛笔字，每一张都是两三行，内容大同小异：
最亲爱的妈妈：
我们都是您含辛茹苦培养大的。
教学课件 我们感念您。
我们承诺：您所有的需要，都由我们承担。请您放心。相信我们对您的深爱。您的孩子：家萱 家齐 家仁
④我看着家萱，忍不住笑。上一回，我们在交换“妈妈笔记”时，她说到八十岁的母亲在安养院里如何如何地焦虑自己没钱，怀疑自己被儿女遗弃，而且一转身就忘记儿女刚刚来探视过而老是抱怨孩子们不记得她。我拿出自己“制造”的各种银行证明、抚养保证书，每一个证明都有拳头大的字，红糊糊、官气赫赫的印章，每一张都有一时的“安心”作用。没想到家萱进步神速，已经有了独家的海报！
⑤“是啊，”她笑着说，“我用海报把她房间的墙壁贴得满满的。她在房间里走来走去，可以一张一张读，每一张我们姐弟都给签了名。”“有效吗？”我问。她点头，“还真有效，她读了就安心。”“你拿回屏东，贴在你妈房里吧。”
⑥她的笑容，怎么看都是苦的。我也发现，她的白发不知何时也多了。
⑦我把这些海报一张一张拾起，一张一张叠好，卷起，然后小心地塞回圆筒。摇摇头，“妈妈又过了那个阶段了。她已 经忘了字了。我写的银行证明，现在她也看不懂了。” ⑧回到屏东，春节的爆竹在冷过头的冬天，有一下没一下的，凉凉的，仿佛浸在水缸里的酸菜。陪母亲卧床，她却终夜不眠。窗帘拉上，灭了大灯，她的 两眼晶亮，瞪着空蒙 蒙的黑夜，好像瞪着一个黑色的可以触摸的实体。她伸出手，在空中捏取我看不见的东西。她呼唤我的小名，要我快起床去赶校车，不要迟到了，便当已经准备好。她说隔壁的张某某不是个东西，欠了钱怎么也不还。她问，怎么你爸爸还没回家，不是说理了发就马上回来吗？
⑨我到厨房拿热牛奶给她喝。她不喝。我抚摸她的手，拍她的肩膀，像哄一个婴儿，但是她安静了一会儿又开始躁动。我不断地把她冰冷的手臂放回被窝里，她又固执地将我推开。我把大灯打开，她的幻觉消失，灯一灭，她又回到四十年前既近又远、且真且假的彷徨迷乱世界。
⑩大年初三，二○○八年的深夜，若是从外宇宙看过来，这间房里的灯亮了又暗，暗了又亮，一整夜。清晨四时，我下了床，光脚踩在冰冷的地板上，说：“妈，既然这样，我们干脆出去散步吧。”帮她穿上最暖的衣服，围上围巾，然后牵着她的手，出了门。⑾冬夜的街，很黑，犬吠声自远处幽幽传来，听起来像低声呜咽，在解释一个说不清的痛处。
⑿路底有一家灯火通明的永和豆浆店，我对她说：“走吧，我带你去吃你家乡浙江淳安的豆
教学课件 浆。”她从梦魇中醒来，乖顺地点头，任我牵着她的手，慢慢走。空荡荡的街，只有我，和那生了我的女人。
(选自龙应台《目送》，有删改)【注】龙应台：合湾著名女作家。文中家萱是她的好友。27．“我”和家萱对因年迈而失智的母亲的照顾，有什么相似的做法?阅读②～⑦节，概括回答。(3分)
28．比较下列两个句子，联系上下文，说说甲句在表达上的好处。(3分)甲 我把这些海报一张一张拾起，一张一张叠好，卷起，然后小心地塞回圆筒。乙 我把这些海报一张张拾起，一张张叠好，卷起，然后塞回圆筒。
29．第⑾节作者描写“冬夜的街”和“犬吠声”有什么用意?(3分)
30．文章接近结束才写到散步的内容，却以“散步”为题，你是怎么理解的?(3分)
31．参考下面材料，探究本文所蕴含的思想感情。(4分)材料一 抒情的文章人们有个误解，以为把感觉抒发出来就是了，而忽视了对深刻的要求。深刻，可以是思想，可以是感情。(龙应台)材料二 有人问我：你那个《散步》，是写尊老呢，还是爱幼？或者既尊老又爱幼？我认真回答：看起来当然是既尊老又爱幼，其实我骨子里是想写生命。(莫怀戚)

Get to work on time . Give yourself an extra 15 minutes to make sure you arrive on time.

Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If you are not told your duties, ask for a list. Set daily and weekly goals for yourself.

“USA? Britain? Which country is better to study in?” We often hear such discussion. As China opens its door, studying abroad has become a dream for many Chinese students. They want to learn about the world. It’s true that studying abroad can help students develop themselves. Language skills will improve and it may be easier to fi nd a job.
But there are problems that should be considered. Language is the fi rst. Students must spend a lot of time learning another language and getting used to a different culture.
Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad sinking in an ocean of diffi culties and giving up easily. When they have to take care of themselves, it is hard for the students to study well.
Finally, studying abroad brings a heavy burden to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?
We know that there are many famous people who succeed in great things through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at Athens
Olympics. So when you wonder which country is better to study in, consider whether studying abroad is the right choice.

Jean is a bright young woman who comes from a rich and famous family. She goes to a good university and has everything that money can buy. Well, almost everything. (71) The problem is that the people in Jean’s family are so busy that they can hardly fi nd time to be with her. In fact, Jean is quite lonely.
So Jean spends a lot of time on her QQ. She likes being anonymous (匿名) , talking to people who do not know about her famous family and her rich life. She uses the name Linda on QQ and has made a lot of friends who she keeps in touch with quite often.
Last year Jean made a very special friend on QQ. His name was David and lived in San FranciscoDavid was full of stories and jokes. He and Jean had a common interest in rock music and modern dance. (72So it always took them hours to talk happily on QQ and sometimes they even forgot their time. Of coursethey wanted to know more about each other. David sent a picture of himself. He was a tall, good-lookingyoung man with a big, happy smile. As time went by, they became good friends and often sent cards andsmall things to each other.

7.设有一张8行、8列的方格纸，随便把其中32个方格涂上黑色，剩下的32个方格涂上白色.下面对涂了色的方格纸施行“操作”，每次操作是把任意横行或者竖列上的各个方格同时改变颜色.问能否最终得到恰有一个黑色方格的方格纸?
8.如果正整数p和p+2都是大于3的素数，求证：6|(p+1).
9.房间里凳子和椅子若干个，每个凳子有3条腿，每把椅子有4条腿，当它们全被人坐上后，共有43条腿(包括每个人的两条腿)，问房间里有几个人?
答案：
1.因为|a|=-a，所以a≤0，又因为|ab|=ab，所以b≤0，因为|c|=c，所以c≥0.所以a+b≤0，c-b≥0，a-c≤0.所以
原式=-b+(a+b)-(c-b)-(a-c)=b.
2.因为m<0，n>0，所以|m|=-m，|n|=n.所以|m|<|n|可变为m+n>0.当x+m≥0时，|x+m|=x+m;当x-n≤0时，|x-n|=n-x.故当-m≤x≤n时，
|x+m|+|x-n|=x+m-x+n=m+n.
3.分别令x=1，x=-1，代入已知等式中，得
a0+a2+a4+a6=-8128.
4.略
5.略
6.商式为x2-3x+3，余式为2x-4
7.答案是否定的.设横行或竖列上包含k个黑色方格及8-k个白色方格，其中0≤k≤8.当改变方格的颜色时，得到8-k个黑色方格及k个白色方格.因此，操作一次后，黑色方格的数目“增加了”(8-k)-k=8-2k个，即增加了一个偶数.于是无论如何操作，方格纸上黑色方格数目的奇偶性不变.所以，从原有的32个黑色方格(偶数个)，经过操作，最后总是偶数个黑色方格，不会得到恰有一个黑色方格的方格纸.
8.大于3的质数p只能具有6k+1，6k+5的形式.若p=6k+1(k≥1)，则p+2=3(2k+1)不是质数，所以，p=6k+5(k≥0).于是，p+1=6k+6，所以，6|(p+1).
9.设凳子有x只，椅子有y只，由题意得3x+4y+2(x+y)=43，
即5x+6y=43.
所以x=5，y=3是的非负整数解.从而房间里有8个人.
排列组合问题：
1.有五对夫妇围成一圈，使每一对夫妇的夫妻二人动相邻的排法有
A768种B32种C24种D2的10次方中
解：
根据乘法原理，分两步：
第一步是把5对夫妻看作5个整体，进行排列有5×4×3×2×1=120种不同的排法，但是因为是围成一个首尾相接的圈，就会产生5个5个重复，因此实际排法只有120÷5=24种。
第二步每一对夫妻之间又可以相互换位置，也就是说每一对夫妻均有2种排法，总共又2×2×2×2×2=32种
综合两步，就有24×32=768种。
2若把英语单词hello的字母写错了,则可能出现的错误共有()
