㈠ 阿基米德的小故事英文的加翻譯，急急急！！！

(287-212 B.C.).Archimedes of whole life diligence good learn, with concentration 1 dedicate a body at science, be loyal to a motherland and be subjected to respect of people with speak favorably.Archimedes once detection lever laws with is assign name to with his name of Archimedes' laws.Combine make use of these laws a design variety machine, behavior people, contribute efforts to the motherland.Concerning he usually of detailed circumstance, have already can't research.But concerning his invention creation with protect the story of motherland, spread up to now.

The establishment of lever laws

People since remote antiquity meeting usage lever, and know skillfully usage lever.At Egypt build pyramid of time, the slaves make use of lever to pry heavy piece of stone upwards. The shipbuilding worker use lever to on a ship install a mast.People use to draw water a boom to take water from the inside of the well, etc..But, why can the lever make this?Archimedes detection lever laws previous, is no one can explanation of.At that time, the philosopher have insist to say at the time of speaking of this problem, this BE"evil".Archimedes but deny is what"evil".He know, various phenomenon in the nature, total have nature of reason to explanation.The leverage also has its reason of the nature, his decision it explanation come out.Archimedes process again and again observation, experiment and calculation, finally establishment lever of balance laws.Be, "dint arm and dint(weight) become reverse ratio."In other words, be:The small weight is a big weight of how much cent it a heavy, long the dint arm should be short dint arm of how much times long.The establishment of Archimedes after the lever laws, predict to say, as long as can obtain appropriate lever length, any weight can raise with the pimping strength.It is said that that he once said so of the Hao speech strong language:

"Give me a fulcrum, I to raise the Earth for the ability!"

The Xu after pulling the king in thou hear say to Archimedes:"By dint of the Zeus(the Zeus be the king of many absolute being in Greece myth, supervisor's day, thunder, electricity and rain) take an oath, you say of the matter is really strange, Archimedes!"Archimedes to king explanation the characteristic of lever after, the king say:"Arrive where find a fulcrum, raise the Earth?"

"So of the fulcrum have no."The answer of Archimedes say.

"So call the person believe the divine power of mechanics impossible?" The king say.

"Not, not, you misunderstood, his majesty, I can give you enumerate don't of example."Archimedes say.

The king say:"You bragged too much!You and substitute my push similar and heavy thing, see the words that you speak how."The king is have the problem of a difficulty at that time, be him for Wang2 Zao4 in Egypt 1 very big of ship.The ship after build goodly mobilized Xu to pull the person of the whole city in thou, can not also push it to enter water.Archimedes say:"All right, I substitute you to push this ship."

Archimedes after leave the king make use of the son of lever and pulley reason, design, manufacturing a set of skillful of machine.After readying to everything all, Archimedes invite a king to watch argosy enter water.He hand over to the king a bitter end of heavy rope, let the king lightly pull once.Immediately, that argosy slowly move to move, successfully slippery descended Shui-li, king and big ministers to see so of miracle, good the elephant see play magic similar, astonishment not already!Hence, king letter Archimedes, and to whole country send out an announcement:"From now on and regardless Archimedes speak what, all want to believe him ……"

Measure the hard nut to crack of royal crown

In ordinary people's eyes, Archimedes be a "eccentric".The words which use historian Pu Lu tower gram in the Rome say:"His elephant is an inside the person of evil doctrine, for all of the body of meal and oneself nonchalance."Sometimes, the rice put to call him have a meal on the table, he good the elephant heard, still in the ash of the brazier painting his several sketch.His wife always watch him.Like he use the time that the oil wipe a body, then foolish sit useful oil to draw a case, but forget at the oneself body is make what matter of.His wife is more afraid to send him to arrive to take a shower in bathhouse, this joke is because of king of a new coronation but cause of.

King fore soon call a craftsman create a gold royal crown for him.The king gave craftsman he the gold of the amount for need.The handicraft of craftsman is very brilliant, make of royal crown choiceness interesting and novel, and weight heel at the beginning the gold give by king be similar and heavy.But, someone say toward the king:"Craftsman manufacturing royal crown, privately destroyed one part gold, same heavy silver Chan go in."King after listen to, also the doubt get up, seek Archimedes, his viewpoint measurement, Chan in the gold royal crown have no Chan silver, whether craftsman pocketted gold or not.This time, can Archimedes difficult live.He returned to a home bitterness to think a bitterness to think for a long time, also didn't figure out a way, everyday rice full, feel sleep not good, also don't take a shower, elephant write evil and similar.

One day, king parties person to urge him to make collective report into the temple.His wife see him too soiled, force him take a shower.He at the bathhouse take a shower of time, the brain inside still want to measure the hard nut to crack of royal crown.Suddenly, his attention arrive, be the his body sink in the bathtub of time, have a part water is from the bathtub side overflow.In the meantime, he feel to be deep more into water, his consider more light.Hence, he immediately jump a bathtub, forgot to wear clothes, run to in the street go of the crowd.Part run, part call:"I figured out to come, I figure out come, the way which solve royal crown find out!"

He enter after the imperial palace and say to the king:"Please allow me to do first an experiment, then can pair of result report give you."The approval of the king.Archimedes will with the royal crown similar and heavy gold, a cake of silver and royal crown, put one by one in water basin respectively, see water quantity that the gold bullion eject ratio silver piece the amount of water for eject be little, but the royal crown eject of water the quantity eject than the gold bullion of water quantity many.

Archimedes say to the king:"Royal crown Chan silver!"The king saw experiment and have no a lane understand, let Archimedes give explanation once.Archimedes say:"The wood of one kilogram with the iron of one kilogram comparison, the physical volume of wood be big.If put them into water respectively, the physical volume big wood eject of water quantity, eject than the physical volume small iron of water quantity many.I use this truth on the gold, silver and the royal crown.Because the density of gold be big, but the density of silver be small, so same heavy gold and silver, inevitable is the physical volume of silver big at the physical volume of gold.With same heavy gold bullion and silver piece put into water, so the gold bullion eject of water quantity ratio silver piece of the amount of water be little.The experiment that is just enunciation, the royal crown eject of water quantity ratio gold bullion many, elucidation royal crown of density ratio gold bullion of the density be small, this certificate the royal crown don't use pure gold manufacturing."Archimedes orderly relate and make king letter.Experiment result certificate, that craftsman pocketted gold.

Archimedes' this experiment is the embryo of "hydrostatics".But he don't stay around this up, continue the thorough research float the problem of body.Result detection natural science in of an importance principle-Archimedes' laws.Namely:Immerse object in a kind of liquid China Times, row open of liquid physical volume, equal an object a physical volume for dip into;The maintenance float the buoyancy of body, heel float a body row to open of the weight of the liquid equal.

A spectacular sight that is on the war history

213 B.C., the troops of Rome be lead by the Ma Er Kai road to pull a thou into the nation Xu of make Archimedes.At this time, year already 75-year-old Archimedes, also immediately spare no effort oneself of havings then can, help motherland, stroke enemy.

The Rome commander-in-chief Ma Er Kai road, continue to capture Xu to pull a thou of two city after, more extremely conceited arrogance.He think that as long as use prepare of five dayses time, can offend to sink the city that the national capital Xu pull a thou.But he exactly thoughted of, be because have an old man Archimedes of hair white of passion motherland, break his whole plan.

The be apart from now 2,190 year agos of fight, is be called by the historians:A spectacular sight that is on the war history!

The Ma Er Kai road lead tall ship, from aquatic take the offensive Xu to pull a thou.The soldier of one of his battleship material bow and arrow, sling and light Biao gun, pull Xu thou of the guarder rushed through city go to, then pass on the battleship of offend city machine, make the soldier blunt to pull into the Xu thou.But, Archimedes did full of preparation.When the enemy's fleet be close of time, Archimedes start those huge long ranges of his manufacturing to project machine.The long range project a machine ability pair of more than 200 kilograms of piece of stone, project more than 1,000 rices far.(equal to 18 centuries the artillery range of the big gun)These huge piece of stone, elephant hail ground the dozen is on the battleship, dozen the Ma Er Kai road fluster, the ship sink a soldier dead, one panic.The Ma Er Kai road have to in a great hurry withdraw the battleship for leave to walk.

The Ma Er Kai road again nighttime of decision take the offensive.He think Archimedes in nighttime see not far, etc. fleet arrive city bottom he those huge long ranges project machine to use not top.But, be the Ma Er Kai road take the offensive for nighttime of time, again poured big mildewed.The machine of the short artillery range of Archimedes started, these machines constantly threw a short Biao gun, piece of stone, make the another troops in Rome encounter heavy stroke, even the Ma Er Kai road also almost die.

The Ma Er Kai road is unwilling to give up to capture the scheme that the Xu pull a thou.He still keep pressing troops and forcing his engineers and continue to contest with Archimedes.The result is all bite on granite.Sometimes, Rome take to have blunt battleship of offend the city machine to go to Xu to pull thou of city bottom, defend city open a kind of the machine which hang "long mouth" to move, a cake of piece the rock drop down from the Qing in"long mouth", not but offend city machine dozen smash, and also hit one of battleships pulpy, make the soldier of Rome sink into place of doom.Sometimes return to let go of a kind of cleek from the city, this kind of cleek manipulate with the machine very vivid, the cleek ability hook the ship's bow of Rome naval vessel, then pull a naval vessel and make naval vessel to part turn over to pour, button up into Shui-li.

The Ma Er Kai road made to the utmost various take the offensive means, is all broken by Archimedes' invention.The Rome troops become timid as a mouse, on seeing stretch out a cordage from the over the wall, flee ignominiously to try very hard to escape, and yell:"Archimedes used a kind of machine again to teased us!"

The Ma Er Kai road end had no way, have to pull the city of the thou the Xu round and round to surround and wildly the diagram trap a town people dead.His this kind of way, make Archimedes also incapable is a dint.The Rome troops had been besieging for eight months, the end multiplied by Xu to pull the ancients to spend joyfully festival, but the Shu go in from a deserted city gate sneak attack at the opportunity for guard against and just pull Xu thou offend to sink.

When the Rome troops be blunt to go into the city of time, the Ma Er Kai road once issued order and don't kill this great of physicist.But that time, Archimedes just at his laboratory inside painting his sketch.After soldier is blunt to enter, the feet stepped a voice to trouble him.This kind of trouble, make him surprised to wake up and indignantly shout a way:"Feed!You broke my picture and hurry up to leave!"Result, his excited and bitter provocation soldier in the Rome, Archimedes then die in knife bottom.

Although great physicist Archimedes died in an accident, , he does to the mankind on science of contribute, can't estimate!
二千一百九十年前，在古希臘西西里島的敘拉古國，出現一位偉大的物理學家。他叫阿基米德（公元前287——212年）。阿基米德的一生勤奮好學，專心一志地獻身於科學，忠於祖國，受到人們的尊敬與贊揚。阿基米德曾發現杠桿定律和以他的名字命名的阿基米德定律。並利用這些定律設計了多種機械，為人民、為祖國服務。關於他生平的詳細情況，已無法考證。但關於他發明創造和保衛祖國的故事，卻流傳至今。

杠桿定律的確立

人們從遠古時代起就會使用杠桿，並且懂得巧妙地運用杠桿。在埃及造金字塔的時候，奴隸們就利用杠桿把沉重的石塊往上撬。 造船工人用杠桿在船上架設桅桿。人們用汲水吊桿從井裡取水，等等。但是，杠桿為什麼能做到這一點呢？在阿基米德發現杠桿定律之前，是沒有人能夠解釋的。當時，有的哲學家在談到這個問題的時候，一口咬定說，這是「魔性」。阿基米德卻不承認是什麼「魔性」。他懂得，自然界里的種種現象，總有自然的原因來解釋。杠桿作用也有它自然的原因，他決心把它解釋出來。阿基米德經過反復地觀察、實驗和計算，終於確立了杠桿的平衡定律。就是，「力臂和力（重量）成反比例。」換句話說，就是：小重量是大重量的多少分之一重，長力臂就應當是短力臂的多少倍長。阿基米德確立了杠桿定律後，就推斷說，只要能夠取得適當的杠桿長度，任何重量都可以用很小的力量舉起來。據說他曾經說過這樣的豪言壯語：

「給我一個支點、我就能舉起地球！」

敘拉古國王聽說後，對阿基米德說：「憑著宙斯（宙斯是希臘神話中的眾神之王，主管天、雷、電和雨）起誓，你說的事真是稀奇古怪，阿基米德！」阿基米德向國王解釋了杠桿的特性以後，國王說：「到哪裡去找一個支點，把地球舉起來呢？」

「這樣的支點是沒有的。」阿基米德回答說。

「那麼，要叫人相信力學的神力就不可能了？」 國王說。

「不，不，你誤會了，陛下，我能夠給你舉出別的例子。」阿基米德說。

國王說：「你太吹牛了！你且替我推動一樣重的東西，看你講的話怎樣。」當時國王正有一個困難的問題，就是他替埃及王造了一艘很大的船。船造好後，動員了敘拉古全城的人，也沒法把它推下水。阿基米德說：「好吧，我替你來推這一隻船吧。」

阿基米德離開國王後，就利用杠桿和滑輪的子理，設計、製造了一套巧妙的機械。把一切都准備好後，阿基米德請國王來觀看大船下水。他把一根粗繩的末端交給國王，讓國王輕輕拉一下。頓時，那艘大船慢慢移動起來，順利地滑下了水裡，國王和大臣們看到 這樣的奇跡，好象看耍魔術一樣，驚奇不已！於是，國王信服了阿基米德，並向全國發出布告：「從此以後，無論阿基米德講什麼，都要相信他……」

稱量皇冠的難題

在一般人看來，阿基米德是個「怪人」。用羅馬歷史學家普魯塔克的話說：「他象是一個中了邪術的人，對於飯食和自己的身體全不關心。」有時候，飯擺在桌子上叫他吃飯，他好象沒聽見，仍舊在火盆的灰里畫他的幾何圖形。他的妻子，要時時看守他。譬如他用油擦身的時候，便呆坐著用油在自己身上畫圖案，而忘記原來是作什麼事的了。他的妻子更怕送他到浴堂里去洗澡，這個笑話是因為國王的一個新冠冕而引起的。

國王在前不久，叫一個工匠替他打造一頂金皇冠。國王給了工匠他所需要的數量的黃金。工匠的手藝非常高明，製做的皇冠精巧別致，而且重量跟當初國王所給的黃金一樣重。可是，有人向國王報告說：「工匠製造皇冠時，私下吞沒了一部分黃金，把同樣重的銀子摻了進去。」國王聽後，也懷疑起來，就把阿基米德找來，要他想法測定，金皇冠里摻沒摻銀子，工匠是否私吞黃金了。這次，可把阿基米德難住了。他回到家裡苦思苦想了好久，也沒有想出辦法，每天飯吃不下，覺睡不好，也不洗澡，象著了魔一樣。

有一天，國王派人來催他進宮匯報。他妻子看他太臟了，就逼他去洗澡。他在澡堂洗澡的時候，腦子里還想著稱量皇冠的難題。突然，他注意到，當他的身體在浴盆里沉下去的時候，就有一部分水從浴盆邊溢出來。同時，他覺得入水愈深，則他的體量愈輕。於是，他立刻跳出浴盆，忘了穿衣服，就跑到人群的街上去了。一邊跑，一邊叫：「我想出來了，我想出來了，解決皇冠的辦法找到啦！」

他進皇宮後，對國王說：「請允許我先做一個實驗，才能把結果報告給你。」國王同意了。阿基米德將與皇冠一樣重的金子、一塊銀子和皇冠，分別一一放在水盆里，看金塊排出的水量比銀塊排出的水量少，而皇冠排出的水量比金塊排出的水量多。

阿基米德對國王說：「皇冠摻了銀子！」國王看了實驗，沒有弄明白，讓阿基米德給解釋一下。阿基米德說：「一公斤的木頭和一公斤的鐵比較，木頭的體積大。如果分別把它們放入水中，體積大的木頭排出的水量，比體積小的鐵排出的水量多。我把這個道理用在金子、銀子和皇冠上。因為金子的密度大，而銀子的密度小，因此同樣重的金子和銀子，必然是銀子的體積大於金子的體積。所 以同樣重的金塊和銀塊放入水中，那麼金塊排出的水量就比銀塊的水量少。剛才的實驗表明，皇冠排出的水量比金塊多，說明皇冠的密度比金塊的密度小，這就證明皇冠不是用純金製造的。」阿基米德有條理的講述，使國王信服了。實驗結果證明，那個工匠私吞了黃金。

阿基米德的這個實驗，就是「靜水力學」的胚胎。但他並不停留在這一點上，繼續深入研究浮體的問題。結果發現了自然科學中的一個重要原理——阿基米德定律。即：把物體浸在一種液體中時，所排開的液體體積，等於物體所浸入的體積；維持浮體的浮力， 跟浮體所排開的液體的重量相等。

戰爭史上的一個奇觀

公元前213年，羅馬的軍隊由瑪爾凱路率領進犯阿基米德的國家敘拉古。這時，年已七十五歲的阿基米德，也立刻竭盡自己的所有才能，幫助祖國，打擊敵人。

羅馬統帥瑪爾凱路，接連攻下敘拉古的兩座城後，更加狂妄自大。他認為，只要用五天的准備時間，就可以攻陷國都敘拉古城。但他恰恰沒有想到，就是因為有一位熱愛祖國的白發蒼蒼的老人阿基米德，就把他的一切計劃打破了。

這場距今二千一百九十年前的戰斗，被歷史學家們稱為：戰爭史上的一個奇觀！

瑪爾凱路率領著船隊，從水上進攻敘拉古。他的每隻戰艦上的士兵都裝備著弓箭、投石器和輕鏢槍，要把敘拉古的守衛者趕下城去，然後通過架在戰艦上的攻城機，讓士兵沖進敘拉古。可是，阿基米德做了充分的准備。當敵人的艦隊接近的時候，阿基米德就開動他製造的那些巨大的遠程投射機器。遠程投射機器能把二百多公斤的石塊，投射一千多米遠（相當於18世紀大炮的射程）。這些巨大的石塊，象冰雹似地打在戰艦上，打得瑪爾凱路手忙腳亂，船沉兵死，一片驚慌。瑪爾凱路只得急急忙忙把剩下的戰艦撤走。

瑪爾凱路又決定夜間進攻。他以為夜間阿基米德看不遠，等艦隊到了城下他那些巨大的遠程投射機器就用不上了。可是，當瑪爾凱路夜間進攻的時候，又倒了大霉。阿基米德短射程的機器開動了，這些機器不斷地投擲出短鏢槍、石塊，使羅馬軍隊又一次遭到沉重打擊，連瑪爾凱路也差一點喪命。

瑪爾凱路不甘心放棄佔領敘拉古的企圖。他還是催促軍隊和強迫他的工程師們，繼續同阿基米德較量。結果，都是徒勞。有時，羅馬把帶有攻城機的戰艦沖到敘拉古的城下，守城者就把一種掛著「長嘴」的機器開動起來，一塊塊石頭從「長嘴」里傾落下來，不 但把攻城機打得粉碎，而且也把戰艦砸個稀爛，使羅馬的士兵陷入絕境。有時，還從城上放下一種鐵鉤，這種鐵鉤用機器操縱著十分靈活，鐵鉤能鉤住羅馬兵船的船頭，然後把兵船拉起來，使兵船向一邊翻倒，扣進水裡。

瑪爾凱路使盡了各種進攻手段，都被阿基米德的發明打破了。羅馬軍隊變得膽小如鼠，一看見從牆頭上伸出條繩子，就抱頭鼠竄拚命逃跑，並叫喊著：「阿基米德又使出一種機器來作弄我們了！」

瑪爾凱路最後沒有辦法了，只得把敘拉古城團團圍住，妄圖把城裡的人困死。他的這種辦法，使得阿基米德也無能為力了。羅馬 軍隊一直圍困了八個月，最後乘敘拉古人歡度節日，而疏於防範的機會，從一個冷僻的城門偷襲進去，才把敘拉古攻陷。

當羅馬軍隊沖進城的時候，瑪爾凱路曾下令不要殺害這位偉大的物理學家。可是那時，阿基米德正在他的實驗室里畫他的圖形。士兵沖進後，腳踏聲驚擾了他。這種驚擾，使他驚醒過來，憤怒地喊道：「喂！你弄壞了我的圖畫，趕快跑開些！」結果，他的憤慨激怒了羅馬士兵，阿基米德便死於刀下。

偉大的物理學家阿基米德雖然遇難了，但是，他在科學上給人類做出的貢獻，是無法估量的！

在許多形成因素當中，我將挑選出這些：這個國家優秀的小學教育：歡 迎新技術的勞動者們：獎勵發明者的做法；而且最重要的是美國人在對 那些技術性事物的非言語的、"空間性的"思考方面的天賦。

26. As Eugene Ferguson has pointed out, "A technologist thinks about objects that can not be reced to unambiguous verbal descriptions: they are dealt with in his mind by a visual, nonverbal process...The designer and the inventor.., are able to assemble and manipulate in their minds devices that as yet do not exist".

[參考譯文]

㈢ inside第三關怎麼過 第三關完美通關詳解攻略

INSIDE第三關戰場與水鬼通關攻略：

第三關：戰場與水鬼

1. 越過沙灘，小男孩會經過一片荒涼的城市，走到盡頭可以看到一個下拉的開關，拉動開關可以看到右邊牆上的霓虹燈亮了，霓虹燈顯示的是數字19。這個數字非常 的重要，小男孩可以看到霓虹燈下面有一個板，加上小男孩每在板上站一個人，霓虹燈就會相應的減少數字，只有霓虹燈的數字為零，下一關卡的大門才會打開。小 男孩現在要做的就是收集足夠的木偶，打開大門。
   

2. 向左跑將升降梯啟動，小男孩降至下面一層。一直向右跑，通過樓梯下來，千萬不要直接跳下來，跳下來的話很容易摔死。
   

3. 繼續向右走，會看到一片水域，小男孩潛入到水域當中繼續尋找出路。中間需要上水面呼吸，這點一定要把握好。反正這款游戲有時候小男孩可以在水底遨遊，有時候呼吸超過四次就嗝屁了。這點挺不科學的，玩家無視就好。

4. 出水面以後。上坡尋找支撐點跳上繩索，通過左右搖晃，直接盪到右邊的平台上面。一直向左跳躍進行，有些平台之間的間隔非常的大，玩家最好是一氣呵成的完 成。平台右邊有一個木偶控制器，小男孩通過控制木偶完成爬上原來梯子的動作，帶領著木偶繼續往左進發。看到一個旋轉遙控器，旋轉遙控器，將木偶接上平台。 領著木偶繼續向左走。一直到看到一個有軌的大推車，將推車往回拉動。小男孩通過木偶攀上繩索，到達頂端，從平台上落到推車上面，控制木偶將推車還原。

5. 到達左邊的平台。可以看到一個木頭籬笆，爬上籬笆到達淺水區，一直往左邊走，走到上升控制台出停下。通過控制台解放被鎖在上面的木偶。這里要兩次操作，要 將木板墊到上升控制台地下才行。領著被解放的木偶返回原來的木頭籬笆出，一起拉松動的木板，進入到隱藏空間，順著樓梯下降，一直向左跑就可以看到，中間要 記得點燃火把，因為這個隱藏空間中有三四條狗，有火把狗就不敢上前咬人。(詳見inside隱藏地點，全物品收集)

6. 帶著解放出來的三個工人與之前的工人一起坐上升降梯，回到之前的霓虹燈下會發現還需要帶領7個木偶才能打開大門，往左邊走，打開監獄的大門能夠解放其中3個木偶。坐升降梯繼續上升，到達霓虹燈上的平台，能得到一個已經倒地不起的木偶，將平台左邊的大鐵籠推下平台。

7. 砸碎鐵籠又能獲得三個木偶。加起來正好可以使霓虹燈變成0，打開大門進入戰場。

8. 戰場炮火轟鳴，小男孩需要躲避各種炮彈與被砸碎的鐵皮。一直向右進發，這段難度不高，但是屏幕一直在晃動會讓人很不適應。跳上上升的平台，用鐵門保護自己繼續向右進發。中間會不斷的有落石與炮彈，小男孩需要時刻小心。

9. 控制升降台下降，進入到地底世界，中間升降梯會發生事故，升降梯落入水中，不用擔心，這時候的升降梯門是可以打開的，小男孩可以通過打開的大門逃脫出去。

10. 上岸之後，通過上升裝置，繩索跳到左邊平台，打開右邊的大門，這個速度要求非常快，因為大門會立刻關閉。一不小心就需要重新來過。在進入的密室可以透過玻 璃看到左邊水域中的水鬼，雖然現在水鬼並沒有移動，但是，當小男孩進入水中，水鬼的遊行速度是小男孩的兩倍。小男孩必須盡快游出水面才能避開水鬼的攻擊。 水面上有繩子，平台等輔助工具，小男孩可以通過跳上繩子，爬上平台，來拉開距離，避開水鬼的攻擊。最後通過觸動機關將水鬼關閉在大門的另一邊。

11. 這段闖關需要的不僅僅是腦力，還需要玩家的手速，因為充斥著水域，水域中也一直有水鬼跟著，玩家一個不小心就會收到攻擊。可以說非常驚心動魄。每次水鬼越 靠近小男孩，背景音樂就越大，簡直是把小編的心臟都給嚇出來了。最後小男孩還是被水鬼攻擊到了。但是這一處並不是結束，畫面不會立刻轉暗重新開始。而是被 水鬼拖進了無盡的深淵，在沉到湖泊低端的時候，小孩竟然奇跡般的復活的，難道水鬼還有好壞之分?

12. 湖底左邊有隱藏地點，右邊是下一關的入口，這點小編就不詳細解釋了。感興趣的小夥伴可以關注Inside隱藏地點，全物品攻略。

13. 上岸之後。小男孩向右跑，一定要注意探照燈的照射。被找到就死了。遙控中間的旋轉控制器，可以控制上面的遮擋物，從而躲開探照燈。向左下潛，進入一個開啟 的水下間，向右游就可以看到隱藏物品。這時候你可以看到頂上一層的探照燈也能照射下來。所以需要先去環形控制台控制遮擋物的位置，否則就算是在水底，被探 照燈照到依然是失敗的結局。這里玩家也可以直接通過忽略隱藏物品，但是同樣需要注意探照燈。

14. 通過樓梯爬到天台處，小男孩要注意地面上的陷阱，還有空中的探照燈。千萬不要急沖沖的往前跑，否則一個不小心就是死。到達平台的盡頭，小男孩需要跳下落入 非常小的井口中，平台與著落點落差很大，只要小男孩沒有落入水中就必定摔死。這里真的是一遍又一遍考驗耐心，小編一直瞄準，預備跳，摔死。來來回回好幾 次。所剩無幾的頭發都快被扒光了。

利用杠桿原理解決生活中的問題
公元前245左右,物理學家阿基米德發現了杠桿原理，他曾說過：「給我一個支點，我可以撬動整個地球。」而21世紀的現代社會中，阿基米德所發明的杠桿原理為人們的生活帶來了不小的幫助.
啤酒不少人都喝過，但是有時啤酒瓶蓋打不開怎麼辦？你當然會想到去開瓶器 ，其實開瓶器就利用了杠桿原理，是一種省力杠桿哦，當我們打不開啤酒蓋時，它就能祝我們一臂之力哦，釣魚時，你會發現釣魚竿長長的，我們會疑問，拉魚上鉤時為什麼又這么費力呢？其實這也利用到了杠桿原理，它其實就是一種費力杠桿。工人師傅拔釘子時，往往徒手拔不出，這時，羊角錘就是他們的一大利器，用它輕輕一拔就出來了，其實這也運用了杠桿原理，它是一種省力杠桿....
杠桿原理無處不在，它無時無刻的解決了我們生活 大大小小的問題，只要你細心尋找，你就會發現，生活離不開杠桿原理！

㈦ 在籃球中inside out什麼意思

Inside-Out戰術是籃球基本戰術之一，有時候也被稱之為In-Out，翻譯被稱為內-外戰術。

這種戰術的根本構成是一名內線具有攻擊力的大個子球員，配合若干外圍射籃能力的小個子進行展開。其精髓部分是中鋒底線的牽制，並且無球球員通過移動製造射籃機會。

在籃球運動中，運球過人是一種打開防守者大門的一個重要方式，在運球過人中又有變向過人之分。inside out是變向過人中的一種，克里斯保羅經常用這種過人方式。

(7)inside杠桿工人出不來擴展閱讀：

在防守日益增強的現代籃球中，傳遞相對簡單的Inside-Out沒有單獨生存的空間，而是作為更復雜戰術的一個必然組成部分參與到進攻中。Inside-Out通過更為復雜的外圍3人進行2次以上的無球擋拆完成射籃空位的製造。Inside-Out的戰術基礎變化也至少有不下10種。

盡管單純的Inside-Out戰術實戰中實行成功的可能性並不大，可是，需要理解更深層次的戰術組合，Inside-Out是一個基礎課程，掌握不了Inside-Out的球員不可能在戰術理解水平上達到高一層的境界。
