学语文真快乐拼音天天练班级学号姓名亲爱的家长朋友:我们的拼音学习已经开始了。

汉语拼音是学习汉字和学习普通话的工具。

汉语拼音学得好,普通话就能说得更准确,孩子的语文成绩就更好。

汉语拼音的重点是拼读,孩子学会了拼读才可能借助拼音识字和阅读。

为了使孩子更好的掌握拼音,请家长朋友根据老师布置的任务,每天帮助孩子认真练习拼读,并针对孩子当天的练习情况,在《作业登记本》上做出简单评价(熟练、一般、不熟)。

今天不熟明天练,明天练了后天继续练,一定要达到熟练才算过关。

多练习拼读,孩子每天都会有新的进步!马老师2018年10月拼音天天练(一)ɑ o e一、准确认读(要求:熟读3遍以上)ā e ǒàè o áěóǎòēōɑé二、比一比,读一读(要求:熟读3遍以上)ā—ōá—òé—èǎ—ǒā—ěó—ée—ɑǎ—éà—óɑ—ǒǒ—ěō—éè—àà—éò—éá—èǎ—éǒ—è三、熟读儿歌。

第5模块 第1节[知能演练]一、选择题1.已知数列{a n }的通项公式是a n =2n3n +1,那么这个数列是( )A .递增数列B .递减数列C .摆动数列D .常数列 解法一:∵a n +1-a n =2(n +1)3(n +1)+1-2n3n +1=2[3(n +1)+1](3n +1)>0, ∴a n +1>a n ,数列{a n }为递增数列.解法二:研究函数f (x )=2x3x +1(x >0)的单调性,f (x )=2x +23-233x +1=23(3x +1)-233x +1=23-23(3x +1),∴f (x )=2x3x +1在(0,+∞)上单调递增,∴f (n +1)>f (n ),故a n +1>a n ,数列{a n }为递增数列. 答案:A2.数列{a n }中,a 1=1,对于所有的n ≥2,n ∈N *,都有a 1·a 2·a 3·…·a n =n 2,则a 3+a 5等于( )A.6116B.259C.2516D.3115 解法一:由已知得a 1·a 2=22,∴a 2=4.a 1·a 2·a 3=32,∴a 3=94,a 1·a 2·a 3·a 4=42,∴a 4=169,a 1·a 2·a 3·a 4·a 5=52,∴a 5=2516.∴a 3+a 5=94+2516=6116.解法二:由a 1·a 2·a 3·…·a n =n 2,得a 1·a 2·a 3·…·a n -1=(n -1)2,∴a n =(n n -1)2(n ≥2),∴a 3+a 5=(32)2+(54)2=6116.答案:A3.若数列{a n }的通项公式a n =1(n +1)2,记f (n )=2(1-a 1)·(1-a 2)…(1-a n ),试通过计算f (1),f (2),f (3)的值,推测出f (n )为( )A.n +1nB.n +3n +1C.n +2n +1D.n +3n +2解析:f (1)=2(1-a 1)=32=1+21+1,f (2)=2(1-14)(1-19)=43=2+22+1,f (3)=2(1-a 1)(1-a 2)(1-a 3)=2(1-14)(1-19)(1-116)=54=3+23+1,可猜测f (n )=n +2n +1.答案:C4.已知数列{a n }的前n 项和S n =n 2-9n ,第k 项满足5<a k <8,则k 等于( )A .9B .8C .7D .6解析:∵S n =n 2-9n ,∴当n ≥2时,a n =S n -S n -1=2n -10. 又当n =1时,a 1=S 1=-8也适合上式,∴a n =2n -10,又5<2k -10<8,152<k <9,∴k =8.答案:B 二、填空题5.数列{a n }满足a n +1=⎩⎨⎧2a n , 0≤a n <12,2a n -1, 12≤a n <1,a 1=35,则数列的第2008项为________.解析:∵a 1=35,∴a 2=2a 1-1=15,∴a 3=2a 2=25,∴a 4=2a 3=45,a 5=2a 4-1=35,a 6=2a 5-1=15…,∴该数列的周期为T =4.∴a 2008=a 4=45.答案:456.已知数列{a n }中,a 1=1,(n +1)a n =na n +1,则数列{a n }的一个通项公式a n =________. 解法一:由a 1=1,(n +1)a n =na n +1, 可得a 2=2,a 3=3,a 4=4, ∴数列的通项公式a n =n .验证:当a n =n 时,(n +1)a n =na n +1成立.解法二:由(n +1)a n =na n +1可得a n +1a n =n +1n .∴当n ≥2时,a n a n -1=n n -1,a n -1a n -2=n -1n -2,…,a 3a 2=32,a 2a 1=2.将以上各式累乘求得a na 1=n ,∴a n =n ,而n =1时也适合.∴数列的通项公式为a n =n . 答案:n三、解答题7.已知数列{a n }的前n 项和为S n ,满足log 2(1+S n )=n +1,求数列的通项公式.解:S n 满足log 2(1+S n )=n +1,∴1+S n =2n +1,∴S n =2n +1-1.∴a 1=3,a n =S n -S n -1=(2n +1-1)-(2n -1)=2n (n ≥2),∴{a n }的通项公式为a n =⎩⎪⎨⎪⎧3 (n =1),2n (n ≥2).8.在数列{a n }中,a 1=12,a n =1-1a n -1(n ≥2,n ∈N *),数列{a n }的前n 项和为S n .(1)求证:a n +3=a n ; (2)求a 2008.(1)证明:a n +3=1-1a n +2=1-11-1a n +1=1-11-11-1a n =1-11-1a n -1a n=1-11-a n a n -1=1-1a n -1-a na n -1=1-1-1a n -1=1-(1-a n )=a n .∴a n +3=a n .(2)解:由(1)知数列{a n }的周期T =3,a 1=12,a 2=-1,a 3=2.又∵a 2008=a 3×669+1=a 1=12.∴a 2008=12.[高考·模拟·预测]1.记数列{a n }的前n 项和为S n ,且S n =2(a n -1),则a 2=( )A .4B .2C .1D .-2解析:取n =1得a 1=2(a 1-1),所以a 1=2,再由n =2得2+a 2=2(a 2-1),所以a 2=4.答案:A2.在数列{a n }中,若a 1=1,3a n a n -1+a n -a n -1=0(n ≥2,n ∈N *),则通项a n 是( )A.2n +13B.n +23C.12n -1D.13n -2解析:将3a n a n -1+a n -a n -1=0的两边同时除以a n a n -1(a n a n -1≠0)得:3+1a n -1-1a n=0,1a n -1a n -1=3,故数列{1a n }是首项为1,公差为3的等差数列,1a n =1a 1+(n -1)×3=3n -2,故通项a n =13n -2.答案:D3.已知数列{a n }的前n 项和S n =n (20-n ),则当a n a n +1<0时,n =________.解析:由S n =n (20-n )得,当n ≥2时,a n =S n -S n -1=n (20-n )-(n -1)[20-(n -1)]=-2n +21; 当n =1时,a 1=S 1=1×(20-1)=19=-2×1+21. 故数列{a n }的通项公式为a n =-2n +21.由a n ·a n +1=(-2n +21)[-2(n +1)+21]=(-2n +21)(-2n +19)<0⇔192<n <212,因为n ∈N ,所以n =10.答案:104.设a 1=2,a n +1=2a n +1,b n =|a n +2a n -1|,n ∈N *,则数列{b n }的通项b n =________.解析:∵b n +1=⎪⎪⎪⎪⎪⎪a n +1+2a n +1-1=⎪⎪⎪⎪⎪⎪2a n +1+22a n +1-1= ⎪⎪⎪⎪⎪⎪2(a n +2)a n +1-(a n -1)a n +1=⎪⎪⎪⎪⎪⎪-2(a n +2)a n -1=2b n ,∴b n +1=2b n.又b 1=4,∴b n =4·2n -1=2n +1.答案:2n +15.设数列{a n }的前n 项和为S n ,已知a 1=1,S n +1=4a n +2. (1)设b n =a n +1-2a n ,证明数列{b n }是等比数列; (2)求数列{a n }的通项公式.解:(1)由已知有a 1+a 2=4a 1+2,解得a 2=3a 1+2=5,故b 1=a 2-2a 1=3.又a n +2=S n +2-S n +1=4a n +1+2-(4a n +2)=4a n +1-4a n , 于是a n +2-2a n +1=2(a n +1-2a n ),即b n +1=2b n . 因此数列{b n }是首项为3,公比为2的等比数列.(2)由(1)知等比数列{b n }中b 1=3,公比q =2,所以a n +1-2a n =3×2n -1,于是a n +12n +1-a n 2n =34,因此数列{a n 2n }是首项为12,公差为34的等差数列,a n 2n =12+(n -1)×34=34n -14,所以a n =(3n -1)·2n -2.[备选精题]6.在数列{a n }中,a 1=1,a n +1=(1+1n )a n +n +12n .(1)设b n =a nn,求数列{b n }的通项公式;(2)求数列{a n }的前n 项和S n .解:(1)由已知得b 1=a 1=1,且a n +1n +1=a n n +12n ,即b n +1=b n +12n ,从而b 2=b 1+12,b 3=b 2+122,……b n =b n -1+12n -1(n ≥2),于是b n =b 1+12+122+…+12n -1=2-12n 1(n ≥2).又b 1=1,故所求的通项公式b n =2-12n 1.(2)由(1)知,a n =n (2-12n -1)=2n -n2n -1.令T n =∑k =1nk2k -1,则2T n =∑k =1nk2k -2.于是T n =2T n -T n =∑k =0n -112k -1-n2n -1=4-n +22n -1. 又∑k =1n (2k )=n (n +1),所以S n =n (n +1)+n +22n -1-4.。

This is certainly having an influence on the live sports events themselves, and there are both benefits and shortcomings to this.[2]Why has there been such growth in televised sport? For one thing, with digital broadcasting, there are now many more TV channels than there were even ten years ago. Moreover, sport has become an important form of entertainment, appealing to both men and women.[3]When are the benefits of this state of affairs? One obvious advantage to the profession is the addition of money provided by television companies. Large football clubs benefit financially from TV income and the top players can command very large salaries. Less popular sports also receive money that can be used in training and awareness-raising. What’s more, there is a health benefit to some of the population, because through televised sport, more people have become interested in actually playing sport.[4]However,____________________ if so much sport is on television. Considering football again, many small clubs have suffered financial losses recently, as they cannot compete with the large ones. There has been a general falling in ticket sales, especially among smaller clubs. Fewer people attend live matches nowadays, preferring to watch from the comfort of their living room. And ticket prices have risen greatly. [5]To sum up, while televised sport has created many opportunities and benefited certain people and clubs very much, it has also been responsible for changing the nature of live sports events for ever.76.

【答案】
【三年级】
【答案】3500
【解析】500张白纸的厚度是7厘米,现在白纸的厚度是49厘米,是原来的7倍,那么白纸的张数也要是原来的7倍,所以白纸的张数是500x7=3500
【四年级】

【五年级】
【答案】186
【解析】因为三个连续的自然数的和一定是3的倍数,且这个和还是31的倍数,所以最小的和应为31x3=93
又这个是三位数,所以,这三个数的和的最小值是93x2=186.

考前冲刺天天练(1--5)考前冲刺天天练(1--5)冲刺小卷一一、语言文字运用1.在下面一段话的空缺处依次填入词语,最恰当的一项是(3分)朱光潜地告诉我们:一个人只爱好故事而不喜欢诗,文学趣味就会低下,在培养的文学趣味方面,有趣的故事怎么能和有趣味的诗?A.不胜其烦纯净一视同仁B.不厌其烦纯正相提并论C.不厌其烦纯净相提并论D.不胜其烦纯正一视同仁2.下面是一首题为“秦淮晓渡”的绝句,填入横线处的句子意境和谐、对仗工整的一项是(3分)潮长波平岸,。

一声孤棹响,残梦落清淮。

A.乌啼月满街B.月辉洒长街C.莺啼花满枝D.草青风低树3.下列交际用语使用得体的一项是(3分)A.今天的讲座,能够聆听诸位先贤的高论,茅塞顿开,获益匪浅。

B.兹介绍我校傅岷同学前往贵公司参加社会实践,请予接洽为荷。

C.迟暮之年,年华已逝,祝您福如东海长流水,寿比南山不老松!D.三年同窗,朝夕相处,今毕业在即,特赠小照一张,敬请笑纳!4.在下面一段文字的横线处填入语句,衔接最恰当的一项是(3分)由于只有一个人生,颓废者因此把它看作零,堕入悲观的深渊。

事实上,在一个热爱人生而又洞察人生真相的人心中,悲观、执著、超脱三种因素始终都存在着,没有一种会完全消失,智慧就存在于它们此消彼长的动态平衡之中。

两者均未得智慧的真髓。

人生既是零,又是全,是零和全的统一。

不过,这只是一种简化的描述。

执迷者又因此把它看作全,激起占有的热望。

智慧是在两者之间,确切地说,是包容了两者又超乎两者之上。

用全否定零,以反抗虚无,又用零否定全,以约束贪欲,智慧仿佛走着这螺旋形的路。

A.B.C.D.5.阅读右边这幅漫画,对其寓意理解最贴切的一项是(3分)A.要根据实际情况,及时采取有效措施。

B.胸怀大志,不应计较鸡毛蒜皮的小事。

(《礼记学记》)(8)夫仁者,,己欲达而达人。

(《论语雍也》)三、文言文阅读阅读下面的文言文,完成6~9题。

大义感人洪迈理义感人心,其究至于浃肌肤而沦骨髓,不过语言造次之间,初非有怪奇卓诡之事也。

楚昭王遭吴阖庐之祸,国灭出亡,父老送之,王曰:“父老返矣,何患无君!”父老曰:“有君如是其贤也!”相与从之,或奔走赴秦,号哭请救,竟以复国。

汉高祖入关,召诸县豪杰曰:“父老苦秦苛法久矣,吾当王关中,与父老约法三章耳。

凡吾所以来,为父兄除害,非有所侵暴,毋恐!”乃使人与秦吏行至县乡邑,告谕之,秦民大喜。

已而项羽所过残灭,民大失望。

刘氏四百年基业定于是矣。

唐明皇避禄山乱,至扶风,士卒颇怀去就,流言不逊,召入谕之曰:“朕托任失人,致逆胡乱常,须远避其锋。

卿等仓卒从朕,不得别父母妻子,朕甚愧之。

今听各还家,朕独与子弟入蜀,今日与卿等诀。

归见父母及长安父老,为朕致意。

”众皆哭曰:“死生从陛下。

”自是流言遂息。

贼围张巡于雍丘,大将劝巡降,巡设天子画像,帅将士朝之,人人皆泣。

巡引六将于前,责以大义而斩之,士心益劝。

河北四凶称王,李抱真使贾林说王武俊,托为天子之语,曰:“朕前事诚误,朋友失意,尚可谢,况朕为四海之主乎?”武俊即首唱从化。

及奉天诏下,武俊遣使谓田悦曰:“天子方在隐忧,以德绥我,何得不悔过而归之?”王庭凑盗据成德,韩愈宣慰,庭凑拔刃弦弓以逆。

及馆,罗甲士于廷。

愈为言安、史以来逆顺祸福之理,庭凑恐众心动,麾之使出,讫为藩臣。

凡此数端,皆异代而同符也。

国家靖康、建炎之难极矣,不闻有此,何邪?(选自《容斋随笔》,有删节)7. 对下列加点词的解释,不正确的一项是(3 分)A. 其究至于浃肌肤而沦骨髓浃:浸透B. 帅将士朝之帅:带领C. 朋友失意,尚可谢谢:道歉D. 庭凑拔刃弦弓以逆逆:反叛8.下列句子中加点词的用法与意义相同的一组是(3 分)A. 竟以复国微以自文于君亲B. 为父兄除害吾社之行为士先者C. 贼围张巡于雍丘若亡郑有益于君D. 召入谕之曰虽董之以严刑9. 把文中画线的句子翻译成现代汉语。

(4 分)四、作文11. 根据以下材料,选取角度,自拟题目,写一篇不少于800 字的文章;文体不限,诗歌除外。

你说的都是真的,但还有更多真的没说。

(米兰昆德拉)【用心积累】成语纠错:1.号声一响,连长一声“立正”,如潮似浪,热火朝天的操场,顿时万籁俱寂。

万籁俱寂:万籁,自然界万物发出的各种声响。

形容周围环境十分宁静。

人声、号声消失不叫万籁俱寂。

2.你纵使有运斤成风的臂力,也举不起这重若千斤的巨石。

运斤成风:斤,斧头。

原义指挥动斧头,风声呼呼,比喻手法熟练,技术神妙。

不是有力气的意思。

3.筹建办公室组织专门人员反复论证,从长计议,确定了长江二桥通航标准。

从长计议:指放宽时间慢慢商量考虑,不急于作决定,也指慢慢设法解决。

句中可用“从长远考虑”。

4.只见他奋笔疾书,一气呵成,不消片刻,一篇佳作便展现在大家面前。

只是文不加点,难以断句,不能不说是白璧微瑕。

文不加点:点,涂改。

意指文章一气写成,无需修改。

句中误为不加标点。

冲刺小卷二一、语言文字运用阅读下面的文字,完成1—3题。

以前,春联是用毛笔书写的,稍为讲究的用上好墨汁,书写出来的春联字体光洁明亮,还散发出墨香。

那时,在一个村的大门或者祠堂所张贴的春联,无论是内容还是书写都颇为讲究,多数由该村具有文化且毛笔字写得好的族人来,因为张贴在村门口或祠堂的春联是代表该村或家族是否有文化的象征。

村与村之间书写的春联内容地形成一种竞争,串门走亲访友看到那些春联,书写内容和字体都是不拘一格,如同看当今的书法展一样,是一种美的享受。

如今,__________________________________________________。

(4分)四、现代文阅读玉殇霍达小院里清凉如水。

前边琢玉坊的窗纸透着灯光,在“沙沙”的磨玉声中,梁亦清手捧着郑和下西洋的宝船,正在加紧精雕细刻。

合同期限迫在眉睫,蒲老板在等着他,沙蒙·亨特先生在等着他,患难老妻和两个女儿在等着他,他自己也在等着这艘宝船竣工的时刻。

他喘息一下,用粗糙的手掌抚摸着巍峨的宝船,脸上露出了欣慰的笑意。

不容易呀,“马哈吉”【注】郑和,梁亦清陪着您一块儿闯过来了!他注视着器宇轩昂的郑和,注视着甲板上劈风斩浪的一个个人物,仿佛他也加入了那雄壮的行列。

水凳儿又蹬起来,坨子又起来,梁亦清屏弃一切杂念,重又投入专心致志的创作,在三保太监郑和那饱经风霜的眉宇之间做画龙点睛的镂刻。

郑和,这位杰出的中国穆斯林,在他手执罗盘、眼望麦加,指挥着宝船与风浪搏斗的时刻,一定是镇静沉着、胸怀坦荡的。

梁亦清怀着崇高的敬意,紧紧盯着郑和那穿透万里云天冲破万顷碧波的眼睛,惟恐自己睫毛的一闪、心脏的一跳都会影响雕刻的精确,有损于那双眼睛的神采……韩子奇一直守在旁边,目不睛地领受师傅那精湛达到极致的技艺,这是他至高的艺术享受和外人无缘分享的殊荣。

突然之间,他感到师傅的神色有些不大对头。

宝船上,郑和的那双眼睛变得模糊了,仿佛郑和由于远途跋涉的劳累和风浪的颠簸而晕眩了,他要做片刻的歇息了?不,是梁亦清自己的眼睛……眼睛怎么了?像一片薄云遮在面前,缭绕,飘动,他努力把眼睛睁大,再睁大,也无法清晰地看清近在眼前的郑和!梁亦清双脚停止了踏动踏板,微微闭了闭疲倦的眼睛,笑笑说:“这活儿,越到画龙点睛的时候越费眼啦!”韩子奇默默地看看师傅的眼睛。

那双眼睛,深深地陷在眼眶之中,上下眼睑重叠着刀刻一般的三四层纹路,眉毛和睫毛上被玉粉沾染,像冰雪中的树挂,像年代久远的古迹上的霉斑,几十年的琢玉生涯,师傅把自己琢成了一个苍老瘦硬的玉人!“师傅,您歇着吧,这活儿,明儿再接着做……”“要记住,”梁亦清歇息了片刻,似乎觉得眼睛从疲倦中得到了恢复,心境也更加平和、安定,“一个艺人,要把活儿当做自个儿的命,自个儿的心,把命和心都放在活儿上,这活儿做出来才是活的。

历朝历代的能工巧匠,没有一个能活到今天,可他们琢出的玉器呢,不都一个个还活着吗?”坨子又动起来,梁亦清此时完全忘却了自我,把他的命、他的心都和宝船、和郑和融为一体了。
