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.
星期六的早晨,红彤彤的.太陽从东方缓缓升起,照耀着整个大地。一片生机勃勃的景象,空气清新,让人倍感舒心,我和姐姐走在去图书馆的路上。
清晨的街上已经人来人往,车水马龙热闹非凡,我们边走边谈,开心极了,不一会儿就来到了四叉路口,我四面瞧了瞧问姐姐,接下来该怎么走啊!姐姐左思右想,这边瞧瞧,那边看看,也拿不定主意该怎么走,真是寸步难行啊!
姐姐急得像热锅上的蚂蚁,在树底下来来回回的绕着圈,忽然眼前一亮,不由地对我说:“你看,这街上来来往往的人,我们可以去问问他们啊!”正说着,迎面走来一位阿姨,我三步并着两步跑上前,仰起红扑扑的脸问:“阿姨,请问去图书馆的路怎么走啊?你能告诉我吗?”阿姨看了看我耐心地说:“小朋友,你看,向前直走过了红绿灯左转就会看到图书馆了。”我顺着她手所指的方向,点了点头连声说:“谢谢阿姨。”
我们顺着阿姨指引的方向,很快到达了图书馆。
下面谈谈学习毅力的.问题。如果你有坚强的毅力,那么世界上就没有什么难事。学英语关键是能够持之以恒。
在学习过程中,你应该制订一个计划,一天记住几个单词,一天记住一两个句型。你不要小看“持之以恒”的力量。举个例子:
如果你一天背5个单词一年就是1825个单词,相当于初中三年再加高中一年零两个月的词汇量。如果你坚持两年你就能住3650个单词,相当于中学六年包括本科两年的词汇量。
在制订计划时要遵循以下几项原则:
1、计划要切实可行,不要好高务远。上面的例子已经说明,只要你能坚持天天学习,英语一定能学好。
2、要有坚强的毅力,每天都学习,不因为某些事而耽误了学习。如果哪天的工作没有完成,第二天一定要补上。连续不学习的时间不要超过两天。
3、要有一个帐本,哪天学会了哪几个单词,哪几个句型一定记录在案。
4、为了把单词、句型真正学到手,第二天一定要复习第一天的,第三天一定要复习第二天和第一天的内容。
5、所选择的课本可以是一套或两套,千万别太多。实际学英语的书没有什么好坏之分,只要你能按照一套或两
一天中午,小猪在森林找吃的,却迷了路。它心想:这可怎么办?怎么才能回家呢?
这时,从远处来了一头小熊。小猪傲慢地问小熊:狗熊,你知道怎样才能走出这片森林吗?小熊怒目圆瞪,看了他一眼,然后就走开了。小猪自言自语地说:它为什么不理我?它好像很生气的样子。小猪脑子里冒出许多问号。这时,有一只乌龟慢慢从草丛里爬了出来,小猪又问乌龟:老乌龟,怎么才能走出这片森林?乌龟叹了口气,心里想:这真是一个没礼貌的孩子。随后也默默地走开了。小猪很惊讶,心想:为什么大家都不理我呢?它自己一个人在森林里走来走去,还是找不到出去的路。小猪又累又饿又渴,哭了起来。他很害怕,这时猪妈妈找到了小猪,看见小猪在那儿大声哭着,就问:怎么了?小猪把事情的`经过都告诉了妈妈,问:他们怎么都不理我呢?猪妈妈说:那是因为你对他们都不礼貌。小猪听懂了。
和他人说话要礼貌,不能没礼貌。
