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.

建构主义学习理论把创设情境看做是“意义建构”的必要前提。在小学英语教学中，教师可利用多媒体和其他直观教学手段，创设有利于学习者建构意义的情景，加强对句型的感知与理解。例如，为了教学生“行为动词一般现在时态的一般疑问句式及其肯定和否定回答方式”，一位教师在教室前的黑板上方悬挂了一个气球，邀请一个男生和一个女生进行触摸气球的竞赛，并发出“Jump high and touch the balloon”的指令。男生跳得高，碰到了气球;女生则没有触摸到气球。这时，教师很自然地指着男生问其他学生：Does he iump high?学生回答：Yes，he does，再指着女生问：Does she jump high?教师得到的回答自然是No，she doesn’t，这样。学生就在这个真实的情景中自然地理解了该句型的意义。
