Qomolangma—the Most Dangerous Mountain in the World?

One of the most dangerous sports is mountain climbing, and one of the most popular places for this is the Himalayas. The Himalayas run along the southwestern part of China. Of all the mountains, Qomolangma rises the highest and is the most famous.It is 8,844.43 meters high and so is very dangerous to climb. Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather conditions and heavy storms. It is also very hard to take in air as you get near the top.

The first people to reach the top were Tenzing Norgay and Edmund Hillary on May 29, 1953.The first Chinese team did so in 1960, while the first woman to succeed was Junk Tabei from Japan in 1975.

Why do so many climbers risk their lives? One of the main reasons is that people want to challenge themselves in the face of difficulties.The spirit of these chmbers shows us that 我们应当永不放弃尝试实现我们的梦想。It also shows that humans can sometimes be stronger than the forces of nature.

作文:(略)

初二上册数学压轴题

解:(1)在ΔABC和ΔAEP中,

∵∠ABC=∠AEP,∠BAC=∠EAP,

∴∠ACB=∠APE,

在ΔABC中,AB=BC,

∴∠ACB=∠BAC,

∴∠EPA=∠EAP;

(2) 答:□APCD是矩形,

∵四边形APCD是平行四边形,

∴AC=2EA,PD=2EP,

∵由(1)知 ∠EPA=∠EAP,

∴EA=EP,则AC=PD,

∴□APCD是矩形;

(3)答:EM=EN,

∵EA=EP,

∴∠EPA=90°-α,

∴∠EAM=180°-∠EPA=180°-(90°-α)=90°+α,

由(2)知∠CPB=90°,F是BC的中点,

∴FP=FB,

∴∠FPB=∠ABC=α,

∴∠EPN=∠EPA+∠APN=∠EPA+∠FPB=90°-α+α=90°+α,

∴∠EAM=∠EPN,

∵∠AEP绕点E顺时针旋转适当的角度,得到∠MEN,

∴∠AEP=∠MEN,

∴∠AEP-∠AEN=∠MEN-∠AEN,

即∠MEA=∠NEP,

∴ΔEAM≌ΔEPN,

∴EM=EN。

参考答案

一、选择题

1、C 2、B 3、A 4、B 5、B 6、D

7、A 8、A 9、D 10、D 11、C 12、C

二、填空题

13、 ,3 14、< 15、 16、 或 17、A=2,B=-2 18、88分

三、解答题

19、解: =

= =

∵a2+2a-8=0,∴a2+2a=8

∴原式= =

20、解:

经检验: 不是方程的解

∴原方程无解

21、1°可以作BC边的垂直平分线,交AB于点D,则线段CD将△ABC分成两个等腰三角形

2°可以先找到AB边的中点D,则线段CD将△ABC分成两个等腰三角形

3°可以以B为圆心,BC长为半径,交BA于点BA与点D,则△BCD就是等腰三角形。

22、(1)证明:∵四边形ABCD为平行四边形

∴AB∥CD,AD∥BC,AD=BC

∴∠AGD=∠CDG,∠DCF=∠BFC

∵DG、CF分别平分∠ADC和∠BCD

∴∠CDG=∠ADG,∠DCF=∠BCF

∴∠ADG=∠AGD,∠BFC=∠BCF

∴AD=AG,BF=BC

∴AF=BG

(2)∵AD∥BC ∴∠ADC+∠BCD=180°

∵DG、CF分别平分∠ADC和∠BCD

∴∠EDC+∠ECD=90° ∴∠DFC=90°∴∠FEG=90°

因此我们只要保证添加的条件使得EF=EG就可以了。

我们可以添加∠GFE=∠FGD,四边形ABCD为矩形,DG=CF等等。

23、1)78,80(2)13(3)选择张成,因为他的成绩较稳定,中位数和众数都较高

24、(1) (2)20分钟

25、解:设甲、乙两队独做分别需要x天和y天完成任务,根据题意得:

解得: , 经检验: , 是方程组的解。

答:甲、乙两队独做分别需要24天和28天完成任务。

26、证明:连接CE∵四边形ABCD为正方形

∴AB=BC,∠ABD=∠CBD=45°,∠C=90°

∵EF⊥BC,EG⊥CD

∴四边形GEFC为矩形∴GF=EC

在△ABE和△CBE中

∴△ABE≌△CBE

∴AE=CE∴AE=CF

阅读下面短文,按要求完成后面各题。

Qomolangma—the Most Dangerous Mountain in the World?

One of the most dangerous sports is mountain climbing, and one of the most popular places for this is the Himalayas. The Himalayas run along the southwestern part of China. Of all the mountains, Qomolangma rises the highest and is the most famous.It is 8,844.43 meters high and so is very dangerous to climb. Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather conditions and heavy storms. It is also very hard to take in air as you get near the top.

The first people to reach the top were Tenzing Norgay and Edmund Hillary on May 29, 1953.The first Chinese team did so in 1960, while the first woman to succeed was Junk Tabei from Japan in 1975.

Why do so many climbers risk their lives? One of the main reasons is that people want to challenge themselves in the face of difficulties.The spirit of these chmbers shows us that 我们应当永不放弃尝试实现我们的梦想。It also shows that humans can sometimes be stronger than the forces of nature.

初二上册数学压轴题

解:(1)在ΔABC和ΔAEP中,

∵∠ABC=∠AEP,∠BAC=∠EAP,

∴∠ACB=∠APE,

在ΔABC中,AB=BC,

∴∠ACB=∠BAC,

∴∠EPA=∠EAP;

(2) 答:□APCD是矩形,

∵四边形APCD是平行四边形,

∴AC=2EA,PD=2EP,

∵由(1)知 ∠EPA=∠EAP,

∴EA=EP,则AC=PD,

∴□APCD是矩形;

(3)答:EM=EN,

∵EA=EP,

∴∠EPA=90°-α,

∴∠EAM=180°-∠EPA=180°-(90°-α)=90°+α,

由(2)知∠CPB=90°,F是BC的中点,

∴FP=FB,

∴∠FPB=∠ABC=α,

∴∠EPN=∠EPA+∠APN=∠EPA+∠FPB=90°-α+α=90°+α,

∴∠EAM=∠EPN,

∵∠AEP绕点E顺时针旋转适当的角度,得到∠MEN,

∴∠AEP=∠MEN,

∴∠AEP-∠AEN=∠MEN-∠AEN,

即∠MEA=∠NEP,

∴ΔEAM≌ΔEPN,

∴EM=EN。

三、解答题

19、解: =

= =

∵a2+2a-8=0,∴a2+2a=8

∴原式= =

20、解:

经检验: 不是方程的解

∴原方程无解

21、1°可以作BC边的垂直平分线,交AB于点D,则线段CD将△ABC分成两个等腰三角形

2°可以先找到AB边的中点D,则线段CD将△ABC分成两个等腰三角形

3°可以以B为圆心,BC长为半径,交BA于点BA与点D,则△BCD就是等腰三角形。

22、(1)证明:∵四边形ABCD为平行四边形

∴AB∥CD,AD∥BC,AD=BC

∴∠AGD=∠CDG,∠DCF=∠BFC

∵DG、CF分别平分∠ADC和∠BCD

∴∠CDG=∠ADG,∠DCF=∠BCF

∴∠ADG=∠AGD,∠BFC=∠BCF

∴AD=AG,BF=BC

∴AF=BG

(2)∵AD∥BC ∴∠ADC+∠BCD=180°

∵DG、CF分别平分∠ADC和∠BCD

∴∠EDC+∠ECD=90° ∴∠DFC=90°∴∠FEG=90°

因此我们只要保证添加的条件使得EF=EG就可以了。

我们可以添加∠GFE=∠FGD,四边形ABCD为矩形,DG=CF等等。

23、1)78,80(2)13(3)选择张成,因为他的成绩较稳定,中位数和众数都较高

24、(1) (2)20分钟

25、解:设甲、乙两队独做分别需要x天和y天完成任务,根据题意得:

解得: , 经检验: , 是方程组的解。

答:甲、乙两队独做分别需要24天和28天完成任务。

26、证明:连接CE∵四边形ABCD为正方形

∴AB=BC,∠ABD=∠CBD=45°,∠C=90°

∵EF⊥BC,EG⊥CD

∴四边形GEFC为矩形∴GF=EC

在△ABE和△CBE中

∴△ABE≌△CBE

∴AE=CE∴AE=CF
