3只鸟飞进2个鸟巢,则总有一个鸟巢至少有2只鸟,为什么?

楼主自己选择下,这个是关于鸟巢的英文介绍哦:
Beijing National Stadium (Bird's Nest/Olympic Stadium)
The Beijing National Stadium,also known as the bird's nest will be the main track and field stadium for the 2008 Summer Olympics and will be host to the Opening and Closing ceremonies.In 2002 Government officials engaged architects worldwide in a design competition.Pritzker Prize-winning architects Herzog & de Meuron collaborated with ArupSport and China Architecture Design & Research Group to win the competition.The stadium will seat as many as 100,000 spectators during the Olympics,but this will be reduced to 80,000 after the games.It has replaced the original intended venue of the Guangdong Olympic Stadium.The stadium is 330 metres long by 220 metres wide,and is 69.2 metres tall.The 250,000 square metre (gross floor area) stadium is to be built with 36 km of unwrapped steel,with a combined weight of 45,000 tonnes.The stadium will cost up to 3.5 billion yuan (422,873,850 USD/ 325,395,593 EUR).The ground was broken in December 2003,and construction started in March 2004,but was halted by the high construction cost in August 2004.
In the new design,the roof of the stadium had been omitted from the design.Experts say that this will make the stadium safer,whilst reducing construction costs.The construction of the Olympic buildings will continue once again in the beginning of 2005.
In depth
The stadium's appearance is one of synergy,with no distinction made between the facade and the superstructure.The structural elements mutually support each other and converge into a grid-like formation - almost like a bird's nest with its interwoven twigs.The spatial effect of the stadium is novel and radical,yet simple and of an almost archaic immediacy,thus creating a unique historical landmark for the Olympics of 2008.
The stadium was conceived as a large collective vessel,which makes a distinctive and unmistakable impression both from a distance and when seen from up close.It meets all the functional and technical requirements of an Olympic National Stadium,but without communicating the insistent sameness of technocratic architecture dominated by large spans and digital screens.
Visitors walk through this formation and enter the spacious ambulatory that runs full circle around the stands.From there,one can survey the circulation of the entire area including the stairs that access the three tiers of the stands.Functioning like an arcade or a concourse,the lobby is a covered urban space with restaurants and stores that invite visitors to stroll around.Just as birds stuff the spaces between the woven twigs of their nests with a soft filler,the spaces in the structure of the stadium will be filled with inflated ETFE cushions.Originally,on the roof,the cushions were to be mounted on the outside of the structure to make the roof completely weatherproof,but the roof has been omitted from the design in 2004.
While the rain was to be collected for rainwater recuperation,the sunlight was to filter through the translucent roof,providing the lawn with essential ultraviolet radiation.On the facade,the inflated cushions will be mounted on the inside of the structure where necessary,e.g.to provide wind protection.Since all of the facilities -- restaurants,suites,shops and restrooms -- are all self-contained units,it is possible to do largely without a solid,enclosed facade.This allows for natural ventilation of the stadium,which is the most important aspect of the stadium's sustainable design.
The sliding roof was an integral part of the stadium structure.When it was to be closed,it would have converted the stadium into a covered arena; however,the sliding roof was eliminated in an effort to cut costs and increase overall safety of the radical new structure.

With the year of 2007 approaching,good news came from the construction sites of the Olympic projects -- the membrane structure of the outside layer of the National Aquatics Center was completed on the morning of December 26.
Construction of the landmark project,also called the "Water Cube," officially started on December 24,2003.The work on concrete and steel structures was finished in July 2006.On August 1 this year,installation of cushions of membrane structure was officially launched.
With the closure of the outside membrane layer project,the installation of inside cushions will be under way,in a synchronized manner with the indoor fit-up and decoration.Installation of electromechanical equipment and pipes is currently going on and indoor fit-up and decoration will start by the end of the year.The whole project will be completed at the end of 2007.
In accordance with the plan,the venue test event will be launched at the National Aquatics Center in February 2008.
The material of membrane structure is called ETFE,or ethylene-tetra-fluoro-ethylene,used for the first time in China.It is also the largest and most complicated membrane system in a single building project internationally.The construction staff of the National Aquatics Center completed all works and fulfilled the goal as planned after overcoming many difficulties,successfully carrying out membrane structure research and independent innovative construction practice.

解题思路：通过在160秒时间内，照片上模糊部分的宽度是△L即为发生的位移，从而由位移与时间的比值来确定冲刺速度．

从照片可得，胸前号码布上模糊部分的宽度是△L
照片后测得照片中人高度为h，博尔特的高度为H，所以冲刺时[1/60]秒内的位移是
H
h△L．
再由位移与时间的比值可得冲刺速度为
60H
h△L
故答案为：
H
h△L，
60H
h△L．

盐城从西汉武帝元狩4年（公元前119年）建立盐渎县,当时这里遍地皆为煮盐亭场,到处是盐河,“渎”就是运盐之河的意思.东晋安帝义熙7年（公元411年）时更名为盐城县,以 “环城皆盐场”而得名.盐城历经了两千多年的历史沉淀,处处散发着浓郁的海盐文化.

鸟巢：Beijing National Stadium (Bird's Nest/Olympic Stadium)

这两个词本身就是专有名词,如果说鸟巢的什么什么应该用它的所有格形式：bird`s nest`s ,the water cube`s 或者用the & of BEIJING NATIONAL STADIUM
the & of the water cube 好的话采纳哦.

A、用力踢足球时，由于人对足球施加的力，使物体的运动状态发生了改变；故A正确；
B、重力在任何情况下都存在，故B错误；
C、羽毛球在空中飞行时，是由于本身的惯性保持了原来的速度，不是因为具有向前的冲力；故C错误；
D、力的作用是相互的，故桨对水有力时，水对桨也会产生力的作用，从而推动皮划艇前进；故D正确；

Tomorrow I will lead my parents to visit the nest

金山词霸上可以查到两个答案：bird nest 和bird's nest.但是,本人认为bird nest比较妥当,正如你所举的例子“苹果树”.我儿子的课本上也写作“bird's nest”,我当时看到也觉得不妥.

鸟巢里的坐席数由原来的10万个减少百分之9,这样使鸟巢的用钢量减少百分之22,只用了4.2万吨钢
（1）鸟巢内实际修建了多少万个座位?
10*(1-9%)
=10*91%
=9.1万个
（2）按原方案修建鸟巢,大约要用几万吨钢?（结果保留一位小数）
4.2/(1-22%)
=4.2/78%
=5.4万吨

叹为观止用错了
语义有问题.叹为观止是形容看到美好的景物等惊讶到说不出话的样子

解题思路：科学记数法的表示形式为a×10ⁿ的形式，其中1≤|a|＜10，n为整数．
确定n的值时，要看把原数变成a时，小数点移动了多少位，n的绝对值与小数点移动的位数相同．
当原数绝对值大于10时，n是正数；当原数的绝对值小于1时，n是负数．

把4.58亿帕转化成科学记数法的表示形式为4.58×10⁸帕．故本题选C．

点评：
本题考点： 科学记数法—表示较大的数．

考点点评： 本题考查用科学记数法表示较大的数．科学记数法在实际生活中有着广泛的应用，给我们记数带来方便，考查科学记数法就是考查我们应用数学的能力．

解题思路：通过在160秒时间内，照片上模糊部分的宽度是△L即为发生的位移，从而由位移与时间的比值来确定冲刺速度．

解题思路：就是求5个20公顷是多少公顷，用乘法计算．

20×5=100公顷，
1平方千米=100公顷，
所以5个鸟巢的占地面积约为约为1平方千米；
故答案为：√．

点评：
本题考点： 整数的乘法及应用

考点点评： 解决此题关键是先求出5个鸟巢的占地面积是多少，再把公顷数换算成平方千米，进而判断．

解题思路：这是一个六位数，最高位十万位上是2，万位上是5，千位上是8，写这个数时，从高位到低位，一级一级地写，哪一个数位上一个单位也没有，就在那个数位上写0；写成用“万”作单位的近似数就是省略“万”后面的尾数求它的近似数，要把万位的下一位千位上的数进行四舍五入，再在数的后面带上“万”字．

二十五万八千写作：258000；
258000≈26万；
故答案为：258000，26．

点评：
本题考点： 整数的读法和写法；整数的改写和近似数．

考点点评： 本题主要考查整数的写法、改写和求近似数，注意改写和求近似数时要带计数单位．
