为什么面包放久了会发硬作文100字【一】
老师让我们每人拿出两张纸，接着，老师也拿出两张纸教我们做。老师先把其中一张纸对折两次，然后，把另一张纸也对折两次。再把那两张纸的\'其中一角向左或向右折出去，但是如果第一个角从左到右折，其他三个角也要从左到右折。下一个角要压住前一个角，最后一个角要塞到第一个角里，这样就完成了。
老师教会我们怎么折之后，让同学们自由叠面包，我叠了好几个。老师让我们出去玩对战。如果你把别人的面包打翻了，你就可以把他的面包赢走。我选的对手是刘子峰。我与刘子峰进行“石头、剪子、布”，我赢了。我先打了一下他的面包，没翻。他接着打了我的面包，也没翻。经过多轮交战后，刘子峰犯规用手把我的面包弄翻了。我立即把我的面包拿回来，对他说：“你犯规。”就在这时，老师说：“第一轮游戏结束。”我们全班都同时停了下来，老师让赢家上来，让赢家再找一个人与自己对战。有一个人选我，可他看到我在将两个面包合成一个，感到还要等很长时间，就找别人对战了。我追悔莫及，早知道这样，我就不把俩面包合成一个了。他们找好了人，就开始战斗，最后剩下4个赢家，老师让那4个互相对战，决出了最后的赢家。
这就是今天老师教我们玩的游戏，真是太好玩了！
为什么面包放久了会发硬作文100字【二】
the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
