在学校,有些同学差不多没有朋友,为甚麽呢?可能他的态度恶劣,或是时常不说话,而最易交上朋友的同学,会是热爱群体,愿意帮助别人的同学了。因为他愿意帮助你,你自然对他产生好感,想跟他交朋友。当然,你自己的态度固然要好,因为如果你性情暴躁,别人也不想跟你交朋友的.。
反之,就算你的态度好,而别人的情绪不好,你就应替他分担部分的忧虑才对。而且,要多接受别人的意见,当然,如果有意见的话,你可和他讨论一下,总胜过顶撞呀。
但是,如果没有朋友,大家想想,会怎样呢?那你一定很寂寞的了。因为,你开心的时候,没有人为你分享,而忧愁的时候,没有人为你分担。所以朋友是不可缺少的,如果你有这份友谊,要十分珍惜啊!
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.
