也就是将读过的书的中心思想、段落大意、内容要点及写作方法等等,以提纲挈领的方式写出来。
也就是阅读后,将自己的心得、、感想等写出来。也叫。
即模仿摘录的精彩句子、段落进行仿写,达到学会运用、学以致用。
即边读边把自己的看法、疑问等或在书上划出表示重点、次重点、疑问等等的符号,或在书的天头、地脑作些评语和注释。这种读书笔记简单易行,但首先得书是自己的,别人的书,不能乱画;即使是自己的书,下批注时也应先多想想:自己的看法对不对?怎么表述才简明,然后才写。因书上的空白处不多,想到就写,写了又感到不合适,那就会把书划得乱七八糟了。
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.
