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.
One day, Paula and Richard decided to make a kite.
First they went out and found two straight sticks of the same length. They brought them back home and tied them with a piece of string into the shape of a cross. Then they took some string and used it to tie the four ends of the sticks together. Then, they spread some brightly coloured paper over the frame and glued it around the string.They stuck a tail made of paper to one of the corners, and tied a long string to the centre of the kite.
On the next windy day, they took the kite to a hill near their house and flew it.
一天,保罗和理查德决定做一个风筝。
首先,他们出门找了两根一样长的直木棍。他们把木棍带回家,用一根绳子把它们绑成十字形。然后他们又拿了些绳子,把木棍的四个顶端连在一起。然后,他们把一些颜色鲜艳的纸涂上胶水,粘在风筝的框架上。他们将纸做的尾巴粘在一角,在风筝中间系上一根长绳。
在接下来的一个有风的日子里,他们就在家附近的小山上放风筝了。
办好卡了,我匆匆地看了看注意事项和使用说明,便准备租车。我身旁的.一根根柱子,就是租车系统。租车系统是自动的,使用操作上说,只要将IC卡放在感应区上停留3秒,便可拔出自行车。
我迫不及待地拿过卡就往感应区上放。只听“嘀”的一声,自行车被成功地借了出来。可我刚骑上路,就发现这辆车十分的沉重,我回头一看,顿时傻了眼——后胎没气。
看来借车的时候也要检查一下车辆的状况再借呀!
我将车还好,准备再借一辆。我选中了一辆编号为910324的自行车。由于我已经成功的借出过一辆,自认为有点熟练了,就随随便便一刷。可能是我刷得太快吧,警报响了起来。我只好向管理员叔叔求救。看来借车时不能太心急,否则就会办“砸”。
我又认真地尝试了一遍,成功了!就这样我骑着公共自行车上路了。
我听了这事,心想:哈哈,终于可以换个妈妈了!不过,怎么对妈妈说呢?我蹑手蹑脚地来到妈妈身边,低着头,小声地说了这件事,生怕她不愿意,没想到妈妈竟然爽快地答应了。
我来到“妈妈出租所”,哇,里面顾客真多,全是像我这么大的孩子。我刚进店,就有一大群妈妈把我团团围住,七嘴八舌地说:“选我,选我……”我想:平时妈妈可爱唠叨了,要不就换一个不唠叨的妈妈吧!
我带着不唠叨妈妈回家了。刚回到家,我就躺在沙发上,吃着零食,喝着牛奶,看着电视,甭提有多开心了。不唠叨妈妈也不管我。到了晚上11点,我才猛地想起家庭作业一个字都没写,急忙拿出作业本,这时,妈妈走了过来,摆摆手说﹕“这么晚了,作业就别写了吧!快点休息。”妈妈都让我别写作业了我就不写了吧。第二天,来到学校,我理所当然地被批评了一顿。唉,这个妈妈可要不得啊!
我又换了一个严厉妈妈。这不,刚到家,妈妈就说:“作业做完了吗,10分钟后我来检查,做不完当心点……”刚回家就写作业,妈妈,你这是要累死我啊!我不情愿地拿出作业本,马不停蹄地写了起来。一写完作业,妈妈就捧来一大堆试卷,说:“抓紧时间,做课外试卷10套,做不完或正确率低都没饭吃!”我都快崩溃了,连忙把这个妈妈退了回去。
换来换去,还是自己的妈妈好啊!我得把妈妈接回来!
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
