动物跟人一样,都需要休息,而且大部分的动物和人睡觉时都会闭上眼睛。可是,你见过金鱼闭上眼睛吗?我想你肯定没见过。
那是不是金鱼不睡觉呢?当然不是,金鱼和我们一样,它也会睡觉,只是我们不容易察觉而已。
其实,金鱼在水中不动时,就是在睡觉,只是因为鱼没有眼睑,所以不会闭眼,看上去就像不睡觉一样。
鱼也有各种各样的睡觉方法。仔细观察我们饲养的金鱼,你就会发现,它们到了夜晚,就会躲到鱼缸内的小假山、水草间等暗处一动不动,这就是金鱼睡觉时的状态。鱼不像人那样有眼睑,在睡觉时能够闭上眼睛。因此,要想看到金鱼睡觉还真不是件容易的事。
除了金鱼,人们还了解到了其他一些鱼类睡觉的状态。如花海猪鱼、细拟隆头鱼、锦鱼等,它们都在海洋底部生活,当夜色来临时,它们就会钻进沙子里,一动不动地睡大觉,这样既安静又能有效地防止天敌的伤害。还有一些鱼如裂嘴鱼、南洋鹦嘴等,它们的身分泌一种特殊的'胶状物质,要睡觉时它们就像小孩子一样吹个大泡泡,胶质的泡泡遇水后会硬化,它们就钻进那个泡泡里,只在嘴边留个小孔,就像在睡袋里一样。
在淡水里生活的鱼大多跟金鱼一样,躲在岩石后、水草间等暗处睡觉。像鲤鱼、鲫鱼会钻进水草里睡觉,而鲻鱼、鲷鱼则在岩石后面睡觉。
有趣的是,还有些鱼类睡觉的时候不需要停下来,像有洄游习性的鱼就能够一边游泳一边睡觉。如金枪鱼、鲭鱼和嘉鱼,不管白天晚上都在不停地游动,使得我们很难弄清楚它们什么时候是在睡觉,什么时候是清醒的。
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
In 2080, cars are going to be different. The car of new type is made from China. The motor is quicker than other cars. The car can be droved 500 kilometers per hour.
Computers are going to be inside every car. It is going to control the car. You don’t need to be worried about the red light.
The car is going to go on special tracks above the city. It would be not so crowded and noisy.
There is a special air conditioner in the car. In winter you can be warm there. In summer you can be pleasantly cool.
If you have this car, you will be very fashionable.
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.
原来啊,妈妈发现了我用计算器验算的坏习惯,就想让我碰碰钉子,改掉这个习惯。她正苦苦冥思时,听见了“滴答滴”的手表的秒针移动的声音,忽然心生一计……
“儿子,来,帮妈妈想想这个问题。”妈妈假装做出百思不得其解的'样子,递给我一张纸,上面写着:294分钟=()小时()分。
看见如此简单的题,我笑着对妈妈说:“老妈,这么简单的问题3年级小学生都会解哟!你老咯!”
妈妈若无其事地说:“别嘲笑我,看看你自己能不能做得出再说!”
“这么简单的题,我都懒得费脑子了,我用计算器帮你算吧!”
我正中妈妈下怀,我用计算器熟练地输入“294÷60”,计算器显示“4。9”,于是我告诉了妈妈是“4小时9分”。
妈妈一下子收起了笑容,严肃起来,说:“你确定是这个答案吗?”
我丈二和尚摸不着头脑,怯生生地回答:“是呀,怎么了?计算器都是这样显示的,计算器怎么可能出错呢?”
“那好,你把4小时9分再换成多少分钟试试!”妈妈说。我照做了,却得出了249分。
“咦?怎么少了45分钟啊?”我惊奇的地叫着。
过了一会儿,我才明白了其中的道理。我恨不得扒开一条地缝钻进去,因为我忘记了计算器是十进制,而钟表是六十进制!
进过这件事,再回想自己因为懒惰使用计算器而导致的自己计算能力下降,都是计算器惹的祸!准确地说,是我的“懒惰”惹的祸!
祸兮福所倚,福兮祸所伏。
正是因为计算器惹的这个“祸”,我改掉了一个坏习惯,没有被不劳而获所吞噬了大脑,这使我一生都受益!
