并驱如故。

刀。狼不敢前,眈眈相向。

毙之。方欲行,转视积薪后,一狼洞其中,意将隧入以攻其后也。身已半入,止露尻尾。屠

自后断其股,亦毙之。乃悟前狼假寐,盖以诱敌。

④狼亦黠矣,而顷刻两毙,禽兽之变诈几何哉?止增笑耳。

鸟并不永久的给人喜悦,有时也给人悲苦。诗人哈代在一首诗里他在圣诞的前夕,炉里

燃着熊熊的火,满室生春,桌上摆着丰盛的筵席,准备着过一个普天同庆的夜晚,蓦然看见

在窗外一片美丽的雪景当中,有一只小鸟蹐局缩缩的在寒枝的梢头踞立,正在啄食一颗残余

的僵冻的果儿,禁不住那料峭的寒风,栽倒地上死了,滚成一个雪团!诗人感喟曰:“鸟!你

连这一个快乐的夜晚都不给我!”我也有过一次类似经验,在东北的一间双重玻璃窗的屋里,

忽然看见枝头有一只麻雀,战栗的跳动抖擞着,在啄食一块干枯的叶子。但是我发见那麻雀

的羽毛特别的长,而且是蓬松戟张着的;像是披着一件蓑衣,立刻使人联想到那垃圾堆上的大群褴褛而臃肿的人,那形容是一模一样的。那孤苦伶仃的麻雀,也就不暇令人哀了。

1. 阅读选段分析文中“鸟并不永久的给人喜悦,有时也给人悲苦。”这句话的作用是什么?

2. 请赏析文中划线句子。

3. 在此段中写道,鸟“有时也给人悲苦”。这与作者看到笼中鸟时的感情有何不同?

(一)赵括纸上谈兵

谓善。括母问奢其故,奢曰:“兵,死地也③,而括易言之④。使⑤赵(赵国)不将括即已,{七年级上册数学寒假作业答案2017}.

若必将之,破赵军者必括也„„”

赵括既代廉颇(赵国大将),悉更约束(规定),易置⑥军吏,秦将白起闻之,纵奇兵

⑦,佯败走,而绝⑧其粮道,分断其军为二,士卒离心,四十余日,军饿,赵括出(带领)

锐率捕战,秦杀赵括,括军败,数十万之众遂降秦,秦悉坑⑨之。

【注释】①奢:赵奢。②难:驳倒。③兵,死地也:用兵打仗,本是危险的场合。④易言之:

把它说得很轻易。⑤使:假使。⑥易置:撤换。⑦纵奇兵:调遣派出变化莫测的军队。⑧绝:

截断。⑨坑:活埋。

(3)赵括既代廉颇 (4)佯败走 ..

2.翻译下列句子。

3.赵奢认为儿子赵括能做大将军带兵打仗吗?他为什么这样认为呢?请选用原文回答。

(二)

那些托后裙的内臣都把手在地上东摸西摸,好像他们正在拾取衣裙似的。他们开步走,

手中托着空气——他们不敢让人瞧出他们实在什么东西也没有看见。

这样,皇帝就在那个富丽的华盖下游行起来了。站在街上和窗子里的人都说:“乖乖!皇上的新装真是漂亮!他上衣下面的后裙是多么美丽!这件衣服真合他的身材!”谁也不愿

意让人知道自己什么也看不见,因为这样就会显示自己不称职,或是太愚蠢。皇帝所有的衣

服从来没有获得过这样的称赞。 .....

“可是他什么衣服也没有穿呀!”一个小孩子最后叫了出来。

“上帝哟,你听这个天真的声音!”爸爸说。于是大家把这孩子讲的话私自低声地传播

开来。

“他并没有穿什么衣服!有一个小孩子说他并没有穿什么衣服呀!”

“他实在是没有穿什么衣服呀!”最后所有的老百姓都说。皇帝有点儿发抖,因为他似

乎觉得老百姓所讲的话是真的。不过他自己心里却这样想:“我必须把这游行大典举行完毕。”

因此他摆出一副更骄傲的神气,他的内臣们跟在他后面走,手中托着一条并不存在的后裙。

1.选文第2自然段中加点的“这样的称赞”指的是什么?

2.皇帝、内臣和老百姓明明都没有看到新装,他们为什么要说假话,装出看见了新装一样?

3.真话从一个孩子的口中说出看,反映了作者的什么态度?

4.皇帝已经知道了真相,可他仍然坚持要把这游行大典举行完毕,而且摆出一副更骄傲的神

气来。这反映了皇帝的什么心理?你对皇帝这时的行为怎么评价?

11.已知a,b,c是均不等于0

的有理数,化简{七年级上册数学寒假作业答案2017}.

12.(1)写出下列各式的结果:

(﹣3)=,(﹣2.5)=(﹣2)=(﹣1.5)=(﹣1)=,(﹣0.5)22222222=,0=,0.5=,1=,1.5=,2=,2.5=,3=.

(2)观察(1)中的计算结果,你能发现什么一般的结论?

13.拉面中的数学问题

截止到2002年3月,由我国拉面高手创造的吉尼斯纪录是用1kg面粉拉扣了21次.

(1)请用计算器计算当时共拉出了多少根细面条?

(2)经测量,当时每扣长为1.29m,那些细面条的总长度能超过珠穆朗玛峰的高度吗?

14.计算:

15.计算:

222222. . 16.已知|x|=4,y=9,求x+y的值是多少?

17.有一张厚度为0.1mm的纸,假设这张纸可以连续对折,如果将它对折20次,会有多厚?假如一层楼有3m高,对折后的纸有多少层楼高?

18.(﹣1)+(﹣1)+(﹣1)+…+(﹣1).

319.(﹣3.2)中底数是 ,幂的符号为 .

7520.我们已经学习了有理数的乘方,根据幂的意义知道10就是7个10连乘.3被是5个3

7253连乘,那么我们怎样计算10×10,3×3呢?

72我们知道10=10×10×10×10×10×10×1010═10×10

72所以10×10=(10×10×10×10×10×10×10)×(10×10)

=10×10×10×10×10×10×10×10×10;

=10

53同理3×3=(3×3×3×3×3)×(3×3×3)

8=3×3×3×3×3×3×3×3=3

325再如a•a=(aaa)•(aa)=a•a•a•a•a=a

729538325也就是10×10=10,3×3=3,a•a=a

观察上面三式等号左端两个幂的指数和右端的底数与指数.你会发现每个等式左端两个幂的底数 .右端幂的底数与左端两个幂的底数 .左端两个幂的指数的与右端幂的指数相

mn等.由此你认为a•a= .

21.

45492320. 22.2×4×(﹣0.125).

23.有一张厚度是0.1毫米的纸,将它对折1次后,厚度为2×0.1毫米.

(1)对折2次后,厚度为多少毫米?3次?4次?5次?10次?

(2)对折20次后,厚度为多少毫米?大概有多少层楼高?(设每层楼高为3米)

24.计算下列各题:

﹣(﹣3)×(﹣2);

44﹣[(﹣3)]÷(﹣3).

25.求1+2+2+2+…+2的值,

232012可令S=1+2+2+2+…+2,

2342013则2S=2+2+2+2+…+2,

2013因此2S﹣S=2﹣1.

232012仿照以上推理,求1+5+5+5+…+5的值.

26.有一张厚度为0.1毫米的纸,将它对折一次后,厚度为2×0.1毫米,求:

(1)对折2次后,厚度为多少毫米?

(2)对折20次后,厚度为多少毫米?

222227.(1)计算0.02,0.2,2,20;

(2)从计算的结果中,你认为底数的小数点向右或向左移动一位,平方数的小数点怎样移动?

(3)底数的小数点向右或向左移动一位,立方数的小数点又怎样移动?

28.生物学家指出:在生态系统中,每输入一个营养级的能量,大约只有10%的能量能够流动到下一个营养级,在H1→H2→H3→H4→H5→H6这条生物链中(H表示第n个营养级,n=1,2,…,6),要使H6获得10kJ的能量,需要H1提供的能量约为多少千焦?

29.如图,把一根绳子折成3折,用剪刀从中剪断,得到几根绳子?若将一根子按上图的方法折成5折,用剪刀从中剪断,得到几根绳子?你试一试,看看答案有什么变化?
